Lower SARS-CoV-2 vaccine responses seen in patients with immune-mediated inflammatory diseases
Ten percent of patients with immune-mediated inflammatory diseases (IMIDs) fail to respond properly to COVID-19 vaccinations regardless of medication, researchers report, and small new studies suggest those on methotrexate and rituximab may be especially vulnerable to vaccine failure.
Even so, it’s still crucially vital for patients with IMIDs to get vaccinated and for clinicians to follow recommendations to temporarily withhold certain medications around the time of vaccination, rheumatologist Anne R. Bass, MD, of Weill Cornell Medicine and the Hospital for Special Surgery, New York, said in an interview. “We’re not making any significant adjustments,” added Dr. Bass, a coauthor of the American College of Rheumatology’s COVID-19 vaccination guidelines for patients with rheumatic and musculoskeletal diseases.
The findings appear in a trio of studies in Annals of the Rheumatic Diseases. The most recent study, which appeared May 25, 2021, found that more than one-third of patients with IMIDs who took methotrexate didn’t produce adequate antibody levels after vaccination versus 10% of those in other groups. (P < .001) A May 11 study found that 20 of 30 patients with rheumatic diseases on rituximab failed to respond to vaccination. And a May 6 study reported that immune responses against SARS-CoV-2 are “somewhat delayed and reduced” in patients with IMID, with 99.5% of a control group developing neutralizing antibody activity after vaccination versus 90% of those with IMID (P = .0008).
Development of neutralizing antibodies somewhat delayed and reduced
Team members were surprised by the high number of vaccine nonresponders in the May 6 IMID study, coauthor Georg Schett, MD, of Germany’s Friedrich-Alexander University Erlangen-Nuremberg and University Hospital Erlangen, said in an interview.
The researchers compared two groups of patients who had no history of COVID-19 and received COVID-19 vaccinations, mostly two shots of the Pfizer-BioNTech vaccine (96%): 84 with IMID (mean age, 53.1 years; 65.5% females) and 182 healthy controls (mean age, 40.8 years; 57.1% females).
The patients with IMID most commonly had spondyloarthritis (32.1%), RA (29.8%), inflammatory bowel disease (9.5%), and psoriasis (9.5%). Nearly 43% of the patients were treated with biologic and targeted synthetic disease-modifying antirheumatic drugs and 23.9% with conventional synthetic DMARDSs. Another 29% were not treated.
All of the controls developed anti–SARS-CoV-2 IgG, but 6% of the patients with IMID did not (P = .003). The gap in development of neutralizing antibodies was even higher: 99.5% of the controls developed neutralizing antibody activity versus 90% of the IMID group. “Neutralizing antibodies are more relevant because the test shows how much the antibodies interfere with the binding of SARS-CoV-2 proteins to the receptor,” Dr. Schett said.
The study authors concluded that “our study provides evidence that, while vaccination against SARS-CoV-2 is well tolerated and even associated with lower incidence of side effects in patients with IMID, its efficacy is somewhat delayed and reduced. Nonetheless, the data also show that, in principle, patients with IMID respond to SARS-CoV-2 vaccination, supporting an aggressive vaccination strategy.”
Lowered antibody response to vaccination for some methotrexate users
In the newer study, led by Rebecca H. Haberman, MD, of New York University Langone Health, researchers examined COVID-19 vaccine response in cohorts in New York City and Erlangen, Germany.
The New York cohort included 25 patients with IMID who were taking methotrexate by itself or with other immunomodulatory medications (mean age, 63.2 years), 26 with IMID who were on anticytokine therapy and/or other oral immunomodulators (mean age, 49.1 years) and 26 healthy controls (mean age, 49.2 years). Most patients with IMID had psoriasis/psoriatic arthritis or RA.
The German validation cohort included 182 healthy subjects (mean age, 45.0 years), 11 subjects with IMID who received TNF inhibitor monotherapy (mean age, 40.8 years), and 20 subjects with IMID on methotrexate monotherapy (mean age, 54.5 years).
In the New York cohort, 96.1% of healthy controls showed “adequate humoral immune response,” along with 92.3% of patients with IMID who weren’t taking methotrexate. However, those on methotrexate had a lower rate of adequate response (72.0%), and the gap persisted even after researchers removed those who showed signs of previous COVID-19 infection (P = .045).
In the German cohort, 98.3% of healthy cohorts and 90.9% of patients with IMID who didn’t receive methotrexate reached an “adequate” humoral response versus just half (50.0%) of those who were taking methotrexate.
When both cohorts are combined, over 90% of the healthy subjects and the patients with IMID on biologic treatments (mainly TNF blockers, n = 37) showed “robust” antibody response. However, only 62% of patients with IMID who took methotrexate (n = 45) reached an “adequate” level of response. The methotrexate gap remained after researchers accounted for differences in age among the cohorts.
What’s going on? “We think that the underlying chronic immune stimulation in autoimmune patients may cause T-cell exhaustion and thus blunts the immune response,” said Dr. Schett, who’s also a coauthor of this study. “In addition, specific drugs such as methotrexate could additionally impair the immune response.”
Still, the findings “reiterate that vaccinations are safe and effective, which is what the recommendations state,” he said, adding that more testing of vaccination immune response is wise.
Insights into vaccine response while on rituximab
Two more reports, also published in Annals of the Rheumatic Diseases, offer insight into vaccine response in patients with IMID who take rituximab.
In one report, published May 11, U.S. researchers retrospectively tracked 89 rheumatic disease patients (76% female; mean age, 61) at a single clinic who’d received at least one dose of a COVID-19 vaccine. Of those, 21 patients showed no sign of vaccine antibody response, and 20 of them were in the group taking rituximab. (The other patient was taking belimumab.) Another 10 patients taking rituximab did show a response.
“Longer duration from most recent rituximab exposure was associated with a greater likelihood of response,” the report’s authors wrote. “The results suggest that time from last rituximab exposure is an important consideration in maximizing the likelihood of a serological response, but this likely is related to the substantial variation in the period of B-cell depletion following rituximab.”
Finally, an Austrian report published May 6 examined COVID-19 vaccine immune response in five patients who were taking rituximab (four with other drugs such as methotrexate and prednisone). Researchers compared them with eight healthy controls, half who’d been vaccinated.
The researchers found evidence that rituximab “may not have to preclude SARS-CoV-2 vaccination, since a cellular immune response will be mounted even in the absence of circulating B cells. Alternatively, in patients with stable disease, delaying [rituximab] treatment until after the second vaccination may be warranted and, therefore, vaccines with a short interval between first and second vaccination or those showing full protection after a single vaccination may be preferable. Importantly, in the presence of circulating B cells also a humoral immune response may be expected despite prior [rituximab] therapy.”
Dr. Bass said the findings reflect growing awareness that “patients with autoimmune disease, especially when they’re on immunosuppressant medications, don’t quite have as optimal responses to the vaccinations.” However, she said, the vaccines are so potent that they’re likely to still have significant efficacy in these patients even if there’s a reduction in response.
What’s next? Dr. Schett said “testing immune response to vaccination is important for patients with autoimmune disease. Some of them may need a third vaccination.”
The American College of Rheumatology’s COVID-19 vaccination guidelines do not recommend third vaccinations or postvaccination immune testing at this time. However, Dr. Bass, one of the coauthors of the recommendations, said it’s likely that postvaccination immune testing and booster shots will become routine.
Dr. Bass reported no relevant disclosures. Dr. Schett reported receiving consulting fees from AbbVie. The May 6 German vaccine study was funded by Deutsche Forschungsgemeinschaft, Bundesministerium für Bildung und Forschung, the ERC Synergy grant 4D Nanoscope, the IMI funded project RTCure, the Emerging Fields Initiative MIRACLE of the Friedrich-Alexander-Universität Erlangen-Nürnberg, the Schreiber Stiftung, and the Else Kröner-Memorial Scholarship. The study authors reported no disclosures. The May 25 study of German and American cohorts was funded by the National Institute of Arthritis and Musculoskletal and Skin Diseases, National Institute of Allergy and Infectious Diseases, Rheumatology Research Foundation, Bloomberg Philanthropies COVID-19 Initiative, Pfizer COVID-19 Competitive Grant Program, Beatrice Snyder Foundation, Riley Family Foundation, National Psoriasis Foundation, and Deutsche Forschungsgemeinschaft. The authors reported a range of financial relationships with pharmaceutical companies. No specific funding was reported for the other two studies mentioned.

FROM ANNALS OF THE RHEUMATIC DISEASES
Rituximab’s serious infection risk in ANCA-vasculitis allayed by antibiotic use
The serious infection risk associated with rituximab treatment for antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is high but can be offset by co-prescribing co-trimoxazole, data from a single-center, retrospective study reaffirm.
Over the course of a 3-year study period, 14 (28%) of 50 patients with AAV treated with rituximab experienced at latest one severe infection defined as a grade 3 or higher event. The incidence of severe infections was 15.4 per 100 person-years.
However, a lower rate of infections was seen in patients who had been co-prescribed co-trimoxazole (trimethoprim and sulfamethoxazole), Francesco Dernie, a fifth-year medical student at the University of Oxford (England), reported at the British Society for Rheumatology annual conference.
“In the case of rituximab, the depletion of B cells and associated immune suppression is a double-edged sword, allowing effective disease control, but also leaving the body vulnerable to opportunistic and severe infections,” Mr. Dernie said at the meeting.
Of the patients who developed a severe infection on rituximab, just 7% had been treated with co-trimoxazole. In comparison, 44% of those who did not get a severe infection had received co-trimoxazole. Multivariate analysis confirmed that co-trimoxazole use was an influencing factor, with an odds ratio (OR) of 0.096 (95% confidence interval, 0.009–0.996; P = .05).
Another finding was that patients with low immunoglobulin G levels (less than 6 g/L) were more likely to develop a severe infection than were those with higher IgG levels. Indeed, the OR for hypogammaglobulinemia and the risk for infection was 8.782 (95% CI, 1.19–64.6; P = .033).
“Our results support the monitoring of IgG levels to identify patients who may be more susceptible to infection, as well as the prescription of prophylactic co-trimoxazole to reduce overall severe infection risk,” Mr. Dernie and associates concluded in their abstract.
It’s a “really important message around co-trimoxazole,” observed Neil Basu, MBChB, a clinical senior lecturer and honorary consultant at the Institute of Infection, Immunity & Inflammation, University of Glasgow (Scotland).
“It still frustrates me when I see that patients haven’t received that while receiving rituximab. Of course, co-trimoxazole can have its problems,” said Dr. Basu, who was not involved in the study. “It’s not uncommon for patients to develop reactions or be intolerant to the drug.”
Raashid Luqmani, DM, a senior coauthor of the work and professor of rheumatology at the Nuffield Department of Orthopaedics, Rheumatology and Musculoskeletal Science, University of Oxford, said: “The tolerance of co-trimoxazole has been remarkably good in this cohort.” If there was a problem with using co-trimoxazole, then “our standard would be to go with trimethoprim alone as the next in line and follow that with inhaled pentamidine. So, it’s kind of following what we would all generally do,” Dr. Luqmani said.
These data add further support for coprescribing antibiotic treatment with rituximab, he suggested.
“Worry about infection, worry about it a lot; not just worry about it, do something about it,” Dr. Luqmani said, and co-trimoxazole “is probably an effective means to do something about it.”
Study details
To look at the characteristics of and risk factors for serious infections associated with rituximab use in AAV, Mr. Dernie and associates retrospectively examined the electronic records of patients who had been treated between August 2016 and August 2019. Follow-up was until August 2020.
Of the 50 patients identified, nearly half (48%) were men. The average age was 60 years, ranging from 25 to 90 years. Most (n = 36; 72%) patients had a diagnosis of granulomatosis with polyangiitis, while another 2 (4%) had microscopic polyangiitis, 1 (2%) had eosinophilic granulomatosis with polyangiitis, and 11 (22%) had an overlapping type of vasculitis or undefined AAV.
Of the 18 severe infection events recorded, most (56%) involved the respiratory tract. Less than one-third (28%) were sepsis or neutropenic sepsis events, and there was one case each (6%) of cellulitis, complicated urinary tract infection, and recurrent wound infection.
There were “small numbers of individual comorbidities that were not sufficient to enter into our regression analysis,” Mr. Dernie noted. “It’s likely that comorbid conditions such as COPD [chronic obstructive pulmonary disease] also contribute to an individual’s risk of developing severe infections, and thus should factor into their individualized management.”
Mr. Dernie acknowledged in discussion: “One of the limitations of the study was we just looked at patients in a time when they were receiving rituximab, so they may have historically been exposed to other treatment options.” However, he added, “they weren’t having any other major DMARDs or immunosuppressive treatments at the time.”
Dr. Luqmani observed: “If you look at Francesco’s data on the hypogammaglobulinemia at the start of rituximab, that probably gives you a good idea of just how immunosuppressed these patients were already before we got to this point.”
Dr. Luqmani added: “I suspect that’s in keeping with a lot of other centers that have started using rituximab an awful lot for patients who previously had episodes of vasculitis treated with other disease-modifying therapies, particularly cyclophosphamide.”
But for how long should co-trimoxazole be given after the last rituximab dose? asked the chair of the session, Richard Watts, DM, of Norwich (England) Medical School. These data are purely observational, so it’s not possible to say, Mr. Dernie noted: “The patients that we included as having co-trimoxazole seem to be on it more or less consistently, permanently,” he said.
What about the best dose? “It’s a tricky one,” Dr. Luqmani said, as “we not only use co-trimoxazole for prophylaxis, but we often also want to use it for treatment of the vasculitis itself.”
It’s very likely that there was a mix of patients in the analysis that had received co-trimoxazole as either a treatment or prophylaxis, which means different doses, he said.
“It might be interesting to know whether there was a difference” between doses used and the prevention of infection, added Dr. Luqmani, “but I suspect the numbers are too small to tell.”
Mr. Dernie, Dr. Luqmani, and the other coauthors had no disclosures.
The serious infection risk associated with rituximab treatment for antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is high but can be offset by co-prescribing co-trimoxazole, data from a single-center, retrospective study reaffirm.
Over the course of a 3-year study period, 14 (28%) of 50 patients with AAV treated with rituximab experienced at latest one severe infection defined as a grade 3 or higher event. The incidence of severe infections was 15.4 per 100 person-years.
However, a lower rate of infections was seen in patients who had been co-prescribed co-trimoxazole (trimethoprim and sulfamethoxazole), Francesco Dernie, a fifth-year medical student at the University of Oxford (England), reported at the British Society for Rheumatology annual conference.
“In the case of rituximab, the depletion of B cells and associated immune suppression is a double-edged sword, allowing effective disease control, but also leaving the body vulnerable to opportunistic and severe infections,” Mr. Dernie said at the meeting.
Of the patients who developed a severe infection on rituximab, just 7% had been treated with co-trimoxazole. In comparison, 44% of those who did not get a severe infection had received co-trimoxazole. Multivariate analysis confirmed that co-trimoxazole use was an influencing factor, with an odds ratio (OR) of 0.096 (95% confidence interval, 0.009–0.996; P = .05).
Another finding was that patients with low immunoglobulin G levels (less than 6 g/L) were more likely to develop a severe infection than were those with higher IgG levels. Indeed, the OR for hypogammaglobulinemia and the risk for infection was 8.782 (95% CI, 1.19–64.6; P = .033).
“Our results support the monitoring of IgG levels to identify patients who may be more susceptible to infection, as well as the prescription of prophylactic co-trimoxazole to reduce overall severe infection risk,” Mr. Dernie and associates concluded in their abstract.
It’s a “really important message around co-trimoxazole,” observed Neil Basu, MBChB, a clinical senior lecturer and honorary consultant at the Institute of Infection, Immunity & Inflammation, University of Glasgow (Scotland).
“It still frustrates me when I see that patients haven’t received that while receiving rituximab. Of course, co-trimoxazole can have its problems,” said Dr. Basu, who was not involved in the study. “It’s not uncommon for patients to develop reactions or be intolerant to the drug.”
Raashid Luqmani, DM, a senior coauthor of the work and professor of rheumatology at the Nuffield Department of Orthopaedics, Rheumatology and Musculoskeletal Science, University of Oxford, said: “The tolerance of co-trimoxazole has been remarkably good in this cohort.” If there was a problem with using co-trimoxazole, then “our standard would be to go with trimethoprim alone as the next in line and follow that with inhaled pentamidine. So, it’s kind of following what we would all generally do,” Dr. Luqmani said.
These data add further support for coprescribing antibiotic treatment with rituximab, he suggested.
“Worry about infection, worry about it a lot; not just worry about it, do something about it,” Dr. Luqmani said, and co-trimoxazole “is probably an effective means to do something about it.”
Study details
To look at the characteristics of and risk factors for serious infections associated with rituximab use in AAV, Mr. Dernie and associates retrospectively examined the electronic records of patients who had been treated between August 2016 and August 2019. Follow-up was until August 2020.
Of the 50 patients identified, nearly half (48%) were men. The average age was 60 years, ranging from 25 to 90 years. Most (n = 36; 72%) patients had a diagnosis of granulomatosis with polyangiitis, while another 2 (4%) had microscopic polyangiitis, 1 (2%) had eosinophilic granulomatosis with polyangiitis, and 11 (22%) had an overlapping type of vasculitis or undefined AAV.
Of the 18 severe infection events recorded, most (56%) involved the respiratory tract. Less than one-third (28%) were sepsis or neutropenic sepsis events, and there was one case each (6%) of cellulitis, complicated urinary tract infection, and recurrent wound infection.
There were “small numbers of individual comorbidities that were not sufficient to enter into our regression analysis,” Mr. Dernie noted. “It’s likely that comorbid conditions such as COPD [chronic obstructive pulmonary disease] also contribute to an individual’s risk of developing severe infections, and thus should factor into their individualized management.”
Mr. Dernie acknowledged in discussion: “One of the limitations of the study was we just looked at patients in a time when they were receiving rituximab, so they may have historically been exposed to other treatment options.” However, he added, “they weren’t having any other major DMARDs or immunosuppressive treatments at the time.”
Dr. Luqmani observed: “If you look at Francesco’s data on the hypogammaglobulinemia at the start of rituximab, that probably gives you a good idea of just how immunosuppressed these patients were already before we got to this point.”
Dr. Luqmani added: “I suspect that’s in keeping with a lot of other centers that have started using rituximab an awful lot for patients who previously had episodes of vasculitis treated with other disease-modifying therapies, particularly cyclophosphamide.”
But for how long should co-trimoxazole be given after the last rituximab dose? asked the chair of the session, Richard Watts, DM, of Norwich (England) Medical School. These data are purely observational, so it’s not possible to say, Mr. Dernie noted: “The patients that we included as having co-trimoxazole seem to be on it more or less consistently, permanently,” he said.
What about the best dose? “It’s a tricky one,” Dr. Luqmani said, as “we not only use co-trimoxazole for prophylaxis, but we often also want to use it for treatment of the vasculitis itself.”
It’s very likely that there was a mix of patients in the analysis that had received co-trimoxazole as either a treatment or prophylaxis, which means different doses, he said.

FDA panel narrowly backs avacopan approval
A panel of federal advisers on May 6 lent support to the ChemoCentryx bid for approval of avacopan for a rare and serious autoimmune condition. But they also flagged concerns about both the evidence supporting claims of a benefit for this experimental drug and its safety.
At a meeting of the Food and Drug Administration’s Arthritis Advisory Committee, panelists voted 10-8 on a question of whether the risk-benefit profile of avacopan is adequate to support approval.
ChemoCentryx is seeking approval of avacopan for antineutrophil cytoplasmic autoantibody (ANCA)–associated vasculitis in the subtypes of granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA).
Regardless of their vote on this approval question, the panelists shared an interest in avacopan’s potential to reduce glucocorticoid use among some patients with ANCA-associated vasculitis, also called AAV. Mara L. Becker, MD, MSCE, the chair of the FDA’s panel, was among the panelists who said they reluctantly voted no.
“It pains me because I really want more steroid-sparing” medicines, said Dr. Becker of Duke University, Durham, N.C., who cited a need to gather more data on avacopan.
Margrit Wiesendanger, MD, PhD, of the Icahn School of Medicine at Mount Sinai, New York, who was among the panelists voting yes, spoke of a need for caution if the FDA approves avacopan.
“Judicious use of this new medication will be warranted and perhaps additional guidance could be given to rheumatologists to help them decide for whom this medication is best,” she said.
Panelists had spoken earlier of avacopan as a possible alternative medicine for people with AAV who have conditions that make glucocorticoids riskier for them, such as those who have diabetes.
Close votes on safety profile, efficacy
The panel also voted 10-8 on a question about whether the safety profile of avacopan is adequate to support approval of avacopan for the treatment of adult patients with AAV.
In addition, the panel voted 9-9 on a question about whether efficacy data support approval of avacopan for the treatment of adult patients with AAV.
The FDA considers the recommendations of its advisory panels, but is not bound by them.
The FDA staff clearly expressed the view that ChemoCentryx fell short with the evidence presented for avacopan approval. Shares of San Carlos, Calif.–based ChemoCentryx dropped sharply from a May 3 closing price of $48.82 to a May 4 closing price of $26.63 after the FDA released the staff’s review of avacopan.
In a briefing prepared for the meeting, FDA staff detailed concerns about the evidence ChemoCentryx is using to seek approval. While acknowledging a need for new treatments for AAV as a rare condition, FDA staff honed in on what they described flaws in the testing of this experimental medicine, which is a small-molecule antagonist of the receptor of C5a, an end product of the complement cascade that acts as a potent neutrophil chemoattractant and agonist.
The FDA usually requires two phase 3 studies for approval of a new medicine but will do so with a single trial in cases of exceptional need, the agency staff said. But in these cases, the bar rises for the evidence provided from that single trial.
Difficulties in interpretation of complex study design
In the case of avacopan, though, the data from the key avacopan trial, Study CL010_168, known as ADVOCATE, there were substantial uncertainties around the phase 3 study design and results, raising questions about the adequacy of this single trial to inform the benefit-risk assessment.
In the briefing document, the FDA staff noted that it had “communicated many of the concerns” about ChemoCentryx’s research earlier to the company.
“Complexities of the study design, as detailed in the briefing document, raise questions about the interpretability of the data to define a clinically meaningful benefit of avacopan and its role in the management of AAV,” the FDA staff wrote.
“We acknowledge that AAV is a rare and serious disease associated with high morbidity and increased mortality. It is also a disease with high unmet need for new therapies. However, FDA wants to ensure that new products have a defined context of use, i.e., how a product would be used, and a favorable benefit-risk assessment for patients,” the staff added.
In addition, there were differences in the assessments performed by investigators and the adjudication committee, most frequently related to the attribution of persistent vasculitis, the FDA staff noted.
Statistical analyses of the primary endpoint using investigators’ estimates “resulted in more conservative estimates of treatment effect, e.g., statistical significance for superiority would no longer be demonstrated,” the FDA staff noted. “While the prespecified analysis used the Adjudicator assessments, the assessment based on the Investigators, experienced in management of vasculitis, may better reflect real-world use.”
Imbalances in use of glucocorticoids and maintenance therapy
Also among the complications in assessing the ADVOCATE trial data were the glucocorticoids taken by patients in the study, the FDA staff said.
In the avacopan arm of the trial, 86% of patients received non–study-supplied glucocorticoids. In addition, more avacopan‐treated patients experienced adverse events and serious adverse events within the hepatobiliary system leading to discontinuation.
Subgroups given different treatments represented another challenge in interpreting ADVOCATE results for the FDA staff.
At week 26, the proportion of patients in disease remission in the avacopan group (72.3%) was noninferior to the prednisone group (70.1%), the FDA staff said in the briefing document.
But at week 52, a disparity was observed between subgroups that had received rituximab and cyclophosphamide (intravenous and oral) induction treatment. The estimated risk difference for disease remission at week 52 was 15.0% (95% CI, 2.2%-27.7%) in the subgroup receiving induction with rituximab and 3.3% (95% CI, –14.8% to 21.4%) in the cyclophosphamide plus maintenance azathioprine subgroup, the agency’s staff said.
“Based on the data, there is no evidence of clinically meaningful treatment effect in the cyclophosphamide induction subgroup,” the FDA staff wrote. “Further, the treatment comparison in the complementary rituximab induction subgroup may not be considered meaningful because these patients did not receive maintenance therapy, i.e., due to undertreating of patients, the effect observed in the rituximab subgroup may not represent a clinically meaningful treatment effect, compared to standard of care.”
Rachel L. Glaser, MD, clinical team leader in FDA’s division of rheumatology and transplant medicine, reiterated these concerns to the advisory committee at the May 6 meeting.
“Throughout the development program, FDA advised the applicant that a noninferiority comparison would not be sufficient to show that avacopan can replaced glucocorticoids as it would be difficult to establish whether avacopan is effective or whether an effect was due to the rituximab or cyclophosphamide administered to both treatment arms,” she said.
In its briefing for the meeting, ChemoCentryx noted the limits of treatments now available for AAV. It also emphasized the toll of the condition, ranging from skin manifestations to glomerulonephritis to life-threatening pulmonary hemorrhage. If untreated, 80% of patients with GPA or MPA die within 2 years of disease onset, ChemoCentryx said in its briefing materials for the meeting.
The side effects of glucocorticoids were well known to the FDA panelists and the ChemoCentryx presenters. Witnesses at an open public hearing told their own stories of depression, anxiety, and irritability caused by these medicines.
During the ChemoCentryx presentation, a presenter for the company, Peter Merkel, MD, MPH, of the University of Pennsylvania, Philadelphia, said avacopan would provide patients with AAV with an alternative allowing them “to go on a much lower glucocorticoids regimen.”
A similar view was presented in a February 2021 editorial in the New England Journal of Medicine, titled “Avacopan – Time to Replace Glucocorticoids?” Written by Kenneth J. Warrington, MD, of the Mayo Clinic, Rochester, Minn., the opinion article called the ADVOCATE trial “a milestone in the treatment of ANCA-associated vasculitis; complement inhibition with avacopan has glucocorticoid-sparing effects and results in superior disease control.”
Dr. Warrington reported no conflicts in connection with his editorial nor payments from ChemoCentryx. He did report grants from other firms such as Eli Lilly.
Julia Lewis, MD, of Vanderbilt University, Nashville, Tenn., was among the more skeptical members of the FDA panel. She was among the “nays” in all three voting questions put to the panel. Still, she said there were signs of “clinically meaningful benefit” in the data presented, but noted that the nonstudy use of glucocorticoids made it difficult to interpret the ADVOCATE results.
Dr. Lewis noted that the FDA usually requires two studies for a drug approval, particularly with a compound not yet cleared for any use. While ANCA-associated vasculitis is rare, it would be possible to recruit patients for another trial of avacopan, adding to the results reported already for avacopan from ADVOCATE, she said.
“Were there to be another study, this would certainly be a supportive study and maybe qualify as two studies,” she said.

While acknowledging a need for new treatments for AAV as a rare condition, FDA staff honed in on what they described flaws in the testing of this experimental medicine, which is a small-molecule antagonist of the receptor of C5a, an end product of the complement cascade that acts as a potent neutrophil chemoattractant and agonist.
The FDA usually requires two phase 3 studies for approval of a new medicine but will do so with a single trial in cases of exceptional need, the agency staff said. But in these cases, the bar rises for the evidence provided from that single trial.
Difficulties in interpretation of complex study design
In the case of avacopan, though, the data from the key avacopan trial, Study CL010_168, known as ADVOCATE, there were substantial uncertainties around the phase 3 study design and results, raising questions about the adequacy of this single trial to inform the benefit-risk assessment.
In the briefing document, the FDA staff noted that it had “communicated many of the concerns” about ChemoCentryx’s research earlier to the company.
“Complexities of the study design, as detailed in the briefing document, raise questions about the interpretability of the data to define a clinically meaningful benefit of avacopan and its role in the management of AAV,” the FDA staff wrote.
“We acknowledge that AAV is a rare and serious disease associated with high morbidity and increased mortality. It is also a disease with high unmet need for new therapies. However, FDA wants to ensure that new products have a defined context of use, i.e., how a product would be used, and a favorable benefit-risk assessment for patients,” the staff added.
In addition, there were differences in the assessments performed by investigators and the adjudication committee, most frequently related to the attribution of persistent vasculitis, the FDA staff noted.
Statistical analyses of the primary endpoint using investigators’ estimates “resulted in more conservative estimates of treatment effect, e.g., statistical significance for superiority would no longer be demonstrated,” the FDA staff noted. “While the prespecified analysis used the Adjudicator assessments, the assessment based on the Investigators, experienced in management of vasculitis, may better reflect real-world use.”
Imbalances in use of glucocorticoids and maintenance therapy
Also among the complications in assessing the ADVOCATE trial data were the glucocorticoids taken by patients in the study, the FDA staff said.
In the avacopan arm of the trial, 86% of patients received non–study-supplied glucocorticoids. In addition, more avacopan‐treated patients experienced adverse events and serious adverse events within the hepatobiliary system leading to discontinuation.
Subgroups given different treatments represented another challenge in interpreting ADVOCATE results for the FDA staff.
At week 26, the proportion of patients in disease remission in the avacopan group (72.3%) was noninferior to the prednisone group (70.1%), the FDA staff said in the briefing document.
But at week 52, a disparity was observed between subgroups that had received rituximab and cyclophosphamide (intravenous and oral) induction treatment. The estimated risk difference for disease remission at week 52 was 15.0% (95% CI, 2.2%-27.7%) in the subgroup receiving induction with rituximab and 3.3% (95% CI, –14.8% to 21.4%) in the cyclophosphamide plus maintenance azathioprine subgroup, the agency’s staff said.
“Based on the data, there is no evidence of clinically meaningful treatment effect in the cyclophosphamide induction subgroup,” the FDA staff wrote. “Further, the treatment comparison in the complementary rituximab induction subgroup may not be considered meaningful because these patients did not receive maintenance therapy, i.e., due to undertreating of patients, the effect observed in the rituximab subgroup may not represent a clinically meaningful treatment effect, compared to standard of care.”
Rachel L. Glaser, MD, clinical team leader in FDA’s division of rheumatology and transplant medicine, reiterated these concerns to the advisory committee at the May 6 meeting.
“Throughout the development program, FDA advised the applicant that a noninferiority comparison would not be sufficient to show that avacopan can replaced glucocorticoids as it would be difficult to establish whether avacopan is effective or whether an effect was due to the rituximab or cyclophosphamide administered to both treatment arms,” she said.
In its briefing for the meeting, ChemoCentryx noted the limits of treatments now available for AAV. It also emphasized the toll of the condition, ranging from skin manifestations to glomerulonephritis to life-threatening pulmonary hemorrhage. If untreated, 80% of patients with GPA or MPA die within 2 years of disease onset, ChemoCentryx said in its briefing materials for the meeting.
The side effects of glucocorticoids were well known to the FDA panelists and the ChemoCentryx presenters. Witnesses at an open public hearing told their own stories of depression, anxiety, and irritability caused by these medicines.
During the ChemoCentryx presentation, a presenter for the company, Peter Merkel, MD, MPH, of the University of Pennsylvania, Philadelphia, said avacopan would provide patients with AAV with an alternative allowing them “to go on a much lower glucocorticoids regimen.”
A similar view was presented in a February 2021 editorial in the New England Journal of Medicine, titled “Avacopan – Time to Replace Glucocorticoids?” Written by Kenneth J. Warrington, MD, of the Mayo Clinic, Rochester, Minn., the opinion article called the ADVOCATE trial “a milestone in the treatment of ANCA-associated vasculitis; complement inhibition with avacopan has glucocorticoid-sparing effects and results in superior disease control.”
Dr. Warrington reported no conflicts in connection with his editorial nor payments from ChemoCentryx. He did report grants from other firms such as Eli Lilly.
Julia Lewis, MD, of Vanderbilt University, Nashville, Tenn., was among the more skeptical members of the FDA panel. She was among the “nays” in all three voting questions put to the panel. Still, she said there were signs of “clinically meaningful benefit” in the data presented, but noted that the nonstudy use of glucocorticoids made it difficult to interpret the ADVOCATE results.
Dr. Lewis noted that the FDA usually requires two studies for a drug approval, particularly with a compound not yet cleared for any use. While ANCA-associated vasculitis is rare, it would be possible to recruit patients for another trial of avacopan, adding to the results reported already for avacopan from ADVOCATE, she said.
“Were there to be another study, this would certainly be a supportive study and maybe qualify as two studies,” she said.
Multiple studies highlight pandemic’s impact on patients with rheumatic disease
Reduced access to medical care, increased mental health issues, poor lifestyle habits, and concern over future care are just some of the patient-reported problems associated with the early phases of the COVID-19 pandemic, according to the results of multiple studies.
Data from the Europe-based REUMAVID study, which surveyed more 1,800 patients between April and July last year, have revealed that 58% of patients with rheumatic and musculoskeletal diseases (RMDs) had their appointments with their rheumatologists canceled, 42% could not get in touch with their primary care physicians, and 52% experienced interrupted visits to mental health specialists.
Not surprisingly, this took a toll on patients’ self-perceived health, with nearly two-thirds stating that they had fair to very poor health, and 47% reporting that their health had worsened. Furthermore, 57% of respondents reported high levels of anxiety, almost 46% were at risk for depression, and 49% reported having poor well-being overall.
“The COVID-19 pandemic has had tremendous impact,” Marco Garrido-Cumbrera, PhD, of the University of Seville, Spain, said at the British Society for Rheumatology annual conference.
Dr. Garrido-Cumbrera, who is key player in the REUMAVID initiative, explained that the project was conceived to respond to concerns raised by the president of the Spanish Federation of Spondyloarthritis Associations (CEADE) about providing the right information to their members.
“First in Italy and then in Spain, it was really difficult to deal with the pandemic and there was a lot of uncertainty from a patient perspective,” Dr. Garrido-Cumbrera said.
Victoria Navarro-Compán, MD, PhD, of La Paz University Hospital, Madrid, who was not involved in the study, observed: “I think this reflects how important collaboration between patient organizations is in order to gather relevant data, and to do it in record time.”
The REUMAVID project was the result of initial collaboration between the Health and Territory Research Group at the University of Seville and CEADE but also involved patient organizations from six other European countries: the National Axial Spondyloarthritis Society, National Rheumatoid Arthritis Society, and Arthritis Action in the United Kingdom; the French Association for the Fight against Rheumatism (AFLAR; L’Association Française de Lutte Anti-Rhumatismale); the National Association of People with Rheumatological and Rare Diseases (APMARR; Associazione Nazionale Persone con Malattie Reumatologiche e Rare) in Italy; Portuguese League Against Rheumatic Diseases (LPCDR; Liga Portuguesa contra as Doenças Reumáticas) in Portugal; the Hellenic League Against Rheumatism (ELEANA) in Greece; and the Cyprus League Against Rheumatism.
Pandemic presented ‘perfect storm’
“We’ve never been so well-communicated as we are now,” said Helena Marzo-Ortega, MD, PhD, a consultant rheumatologist at Leeds Teaching Hospitals NHS Trust in England who participated the REUMAVID project. The beginning of the pandemic was “the perfect storm” in that everybody jumped in to try to do something. This resulted in a myriad of research publications, surveys, and attempts to try to understand and make sense of what was happening.
“Research is being conducted in a more structured manner, and it’s given us a lot of very insightful information,” Dr. Marzo-Ortega added. Obviously, patients are important stakeholders to consult when conducting research into how the pandemic has affected them, she added, as they are the ones who had their lives turned upside down.
“A pandemic knows no boundaries, has no limits, everybody can be affected equally. But patients with rheumatic conditions were at particular risk because of the treatments,” she said. “You can remember how worried we all were initially, and thinking about the potential impact of immunosuppressants and many other aspects of these conditions.”
One of the many positives to come out of the pandemic is the “possibility of doing collaborative research at a worldwide level, not just European,” Dr. Marzo-Ortega said, referring to how the EULAR COVID-19 registries are part of the COVID-19 Global Rheumatology Alliance.
Furthermore, Dr. Marzo-Ortega believes the rheumatology community is now better prepared for any upsurges in COVID-19 or any new potentially pandemic-causing viruses.
“What we know now is that we have to be alert, and we know how to respond. We also know how to communicate effectively in order to be able to improve outcomes, not only for the health of the whole population, but also to protect patients such as ours,” she said.
Rheumatology practice changed practically overnight
The REUMAVID study is not alone in looking at the impact that the COVID-19 pandemic has had on RMD patients’ health and well-being, particularly during periods of lockdown or where patients were advised to “shield.”
There were “near overnight changes to rheumatology practice,” said Chris Wincup, MBBS, a clinical research fellow at University College London (UCL), who presented the findings of another large-scale survey that looked at the early effects of the pandemic nationally in the United Kingdom.
“The recovery of those services has taken time and, speaking with patients, this varies between different locations,” Dr. Wincup noted. “Unfortunately, access to care does remain a major area of unmet need [and] is something that we’re going to need to think about when planning services in the future,” he added.
Between September and October last year, Dr. Wincup and fellow UCL researchers conducted an online survey among 2,054 patients attending U.K. rheumatology clinics. As in the REUMAVID study, accessing care was difficult or very difficult for a substantial proportion of patients. However, getting medication and monitoring “were generally well maintained” despite lockdown measures.
Many patients (57%) had “extremely high levels of worry about their future care being negatively impacted as a result of the pandemic,” Dr. Wincup said, with 44% saying that their current care was worse than before the pandemic and 41% being dissatisfied with the services they were able to access.
While 48% of patients welcomed a more hybrid approach to their care, 69% thought face-to-face appointments with their rheumatologists were important and 49% wanted only face-to-face appointments. “A possible more hybrid approach, compared with pure face-to-face, is going to be something that may be required,” he said.
Different approach taken in CONTAIN Study
A different approach to assessing the impact of the COVID pandemic was taken by researchers at the University of Aberdeen in Scotland, observed Gary Macfarlane, MBChB, PhD.
In the COVID-19 and Musculoskeletal Heath During Lockdown (CONTAIN) study, three well-defined populations of patients from existing cohort studies were looked at prospectively. This included patients with ankylosing spondylitis (AS) and psoriatic arthritis (PsA) participating in two separate British Society for Rheumatology registries, and patients at high risk for developing chronic widespread pain who had been part of the MAmMOTH (Maintaining Musculoskeletal Health) study.
“Our aim was to quantify the changes from the previous prepandemic assessment, focusing on quality of life, changes in lifestyle, and recording what has happened to their musculoskeletal health, including symptoms and disease-specific measures,” Dr. Macfarlane said.
Patients had been invited to participate in June 2020 and were reminded in October 2020 and could respond online or via a postal questionnaire. Some patients were invited to participate in in-depth interviews.
Although the participation rate was low, at 29%, this was typical of studies being conducted at this time due to “survey fatigue,” Dr. Macfarlane said. The CONTAIN study population still included a good number of patients, however, with 596 having AS, 162 PsA, and 296 at risk for chronic widespread pain.
According to Dr. Macfarlane, the CONTAIN study results were “generally reassuring.” Although there was a significant decrease in quality of life as measured by the five-level EQ-5D instrument overall, and in every subgroup population studied, “the magnitude of the decrease was small.” There was no change in disease-specific quality of life in patients with AS, for example.
Levels of pain, anxiety, or depression did increase somewhat, he reported, but the factors that influenced quality of life remained the same before and during the pandemic, such as high levels of deprivation, living in an urban location, low levels of physical activity, and sleep problems.
“Rather surprisingly, sleep problems significantly decreased overall,” Dr. Macfarlane reported. Again, it was only a small change, but “the benefit in terms of the improvement in sleep strengthened with later periods in the follow-up.”
There was also some evidence of increased low-level and high-level physical activity in patients with psoriatic arthritis.
“Mental health is a key issue not just in maintaining musculoskeletal health but also, in terms of the likelihood responding to therapy,” Dr. Macfarlane acknowledged. “Focusing on addressing anxiety is important,” he added.
“Providing enhanced support for self-management, including in relation to pain, is likely to be a priority in the absence of normal health care being available,” he suggested. Importantly, regardless of circumstances, “all patients can be affected.”
The REUMAVID study is conducted by the Health & Territory Research of the University of Seville, with the support of Novartis Pharma AG. The CONTAIN study is supported by the British Society for Rheumatology and Versus Arthritis.

Rituximab benefits seen in neuropsychiatric lupus
Patients with neuropsychiatric manifestations of systemic lupus erythematosus (NPSLE) seem to benefit from rituximab (Rituxan) therapy, according to data from the British Isles Lupus Assessment Group Biologics Register (BILAG-BR).
Indeed, the percentage of patients with active disease, as scored by the BILAG-2004 index or SLEDAI-2K (SLE Disease Activity Index 2000), fell significantly (P < .0001) when comparing pre- and postrituximab treatment scores. There was also a reduction in the dose of oral steroids used.
Interestingly, the use of concomitant cyclophosphamide might enhance the level of improvement seen in some patients, Trixy David, MBBS, reported during an abstract session at the British Society for Rheumatology annual conference.
“Larger-scale studies are warranted to establish the effectiveness of rituximab alone, or in combination with cyclophosphamide, in the treatment neuropsychiatric lupus,” said Dr. David, a clinical research fellow at the University of Manchester (England) and specialist registrar in rheumatology at the Manchester University National Health Service Foundation Trust.
Neil Basu, MBChB, PhD, who chaired the virtual session, called the findings “enlightening” and “descriptive.”
The study “provides some interesting data, which should be tested in a robust, randomized clinical trial,” he agreed, and not that clinicians should now start using rituximab for their NPSLE cases.
Dr. Basu, who is a clinical senior lecturer in rheumatology and honorary consultant rheumatologist at the Institute of Infection, Immunity and Inflammation at the University of Glasgow, added: “It is really important that we do these studies to help support a rationale for such a trial, which are obviously very expensive and require strong evidence before we go down that track. I think these data have really been quite enlightening in that respect.”
Rationale for rituximab in neuropsychiatric lupus
Managing patients with NPSLE remains an area of substantial unmet need. According to a recent review in Rheumatology, “there is a dearth of controlled clinical trials to guide management” and “therapeutic options include symptomatic, antithrombotic, and immunosuppressive agents that are supported by observational cohort studies.”
Despite being seen in at least half of all patients with SLE, neuropsychiatric disease “is not very well studied in patients with lupus, as a lot of large-scale trials tend to exclude patients with active neurological disease,” Dr. David said.
Although it is unclear why neuropsychiatric disease occurs in SLE, it could be “as a result of vascular injury or disruption of the blood brain barrier, thereby allowing the passive diffusion of autoantibodies and cytokines across through the cerebral spinal fluid, thereby generating a proinflammatory response,” Dr. David suggested.
“We know B cells are involved in the pathogenesis of lupus, and rituximab is a chimeric monoclonal antibody that selectively targets CD20-positive B cells and mediates transient B-cell depletion,” she said. Notably, there have been some small studies suggesting that rituximab may be effective in neuropsychiatric lupus, and it is currently widely used to treat refractory lupus in the United Kingdom.
About the BILAG-BR and results
“Our aim was to describe the baseline characteristics and short-term effectiveness of rituximab in patients treated for neuropsychiatric lupus within the BILAG-BR,” Dr. David explained.
Started in 2009, the BILAG-BR now contains information on more than 1,400 individuals with SLE who have been recruited at 62 centers in the United Kingdom. Its purpose is to evaluate the long-term safety and effectiveness of biologic drugs versus standard immunosuppressive therapy such as azathioprine, mycophenolate mofetil, cyclophosphamide, and cyclosporine. To date, 1,229 patients have been treated with biologics, of whom 1,056 have received rituximab.
A total of 74 rituximab-treated patients were identified as having active neuropsychiatric disease, making this “the largest prospective observational cohort to date, to our knowledge,” Dr. David said.
The median age of patients was 45.5 years, the majority was female (82%) and White (74%). The median disease duration was 11.5 years.
A total of 96% had multiple organ involvement and not just neuropsychiatric disease, and 91% were positive for antineutrophil antibodies.
The top six neuropsychiatric manifestations were cognitive dysfunction and lupus headache (both affecting 27.5% of patients); acute confessional state or mononeuropathy (each seen in 10% of patients); and seizure disorder and polyneuropathy, seen in a respective 8.6% and 8.7% of patients. These findings are in line with a 2011 meta-analysis, Dr. David pointed out.
BILAG-2004 scores before and after rituximab treatment were available for 50 patients. The number of patients with a BILAG A score dropped from 24 (48%) at baseline to 7 (14%) after treatment with rituximab, and the number with a BILAG B score declined from 26 (52%) at baseline to 4 (8%) after rituximab (both P < .0001).
There was also a reduction following rituximab treatment in the percentage of patients categorized as having mainly central nervous system disease (70% vs. 11%), peripheral nervous system disease (19% vs. 6%), or both (11% vs. 8%).
Total SLEDAI-2K scores were also reduced following rituximab treatment, from a median of 12 at baseline to 2 (P < .0001).
Pre- and postrituximab oral prednisolone doses were a median of 15 mg and 10 mg (P = .009).
Limitations
“Our data are from a real-world setting of patients who had active neuropsychiatric disease and were treated with rituximab,” Dr. David said. There are of course many limitations that go hand in hand with observational studies.
“There was the issue of missing data,” Dr. David said. It was difficult or not possible to determine what doses of steroids patients were taking after rituximab therapy, particularly in terms of intravenous steroids, and what doses of any other concomitant disease-modifying therapy might have been around the time that patients initiated or stopped rituximab treatment.
“These could have acted as potential confounders,” she acknowledged.
Dr. Basu noted: “My major haziness from it is the uncertainty of knowing why these patients improved. Yes, they had rituximab, but I’m sure also that they probably received high doses of steroids if they had quite severe CNS lupus which was categorized as a BILAG-A or a B.”
Patients may also be given methylprednisolone when clinicians are really concerned, he continued, and “as was quite clearly pointed out,” there was quite a lot of missing data from a steroid perspective.
Dr. David and coinvestigators reported having no conflicts of interest. The BILAG-BR is supported by funding from Lupus UK, GlaxoSmithKline, and Roche. Dr. Basu did not state having any disclosures.
Patients with neuropsychiatric manifestations of systemic lupus erythematosus (NPSLE) seem to benefit from rituximab (Rituxan) therapy, according to data from the British Isles Lupus Assessment Group Biologics Register (BILAG-BR).

FROM BSR 2021
Patient benefits justify price of new lupus nephritis drugs
The prices of two new drugs that have been approved by the Food and Drug Administration for the treatment of lupus nephritis are in “reasonable alignment” with the drugs’ estimated benefits for patients with the disease, the Institute for Clinical and Economic Review has determined.
“Both belimumab [Benlysta] and voclosporin [Lupkynis] are important new treatment options,” Steven Pearson, MD, president of ICER, observed in a summary of the report’s findings.
“Despite remaining uncertainty about both treatments’ longer-term outcomes, their estimated net prices appear to be aligned with their anticipated clinical benefits. ... For patients and clinicians to have responsibly priced options specifically indicated for lupus nephritis is a win for patients and the entire health system,” Dr. Pearson added.
The estimated annual price of belimumab is approximately $43,000 per patient; the estimated annual price for voclosporin is approximately $92,000 per patient.
The incremental cost-effectiveness ratio for belimumab is approximately $90,0000 per quality-adjusted life-year; the corresponding value for voclosporin is higher, at approximately $149,000 per QALY, the ICER authors noted.
The report was published by ICER in April 2021.
Large unmet need for treatment of lupus nephritis
In their report, the ICER reviewed belimumab, a parenteral B-lymphocyte inhibitor, as well as voclosporin, an oral calcineurin inhibitor, as initial treatment of patients with lupus nephritis. Lupus nephritis is a serious complication of systemic lupus erythematosus (SLE).
Belimumab was first approved for the treatment of lupus in adults in the United States in March 2011. In April 2019, it was approved for use for the same indication for children aged 5 years and older. The FDA expanded the indication in December 2020 to include adults with active lupus nephritis who are receiving standard therapy.
Voclosporin was approved for the treatment of lupus nephritis in January 2021.
In the pivotal trials for the two agents, each drug was added to standard induction therapy for lupus nephritis, which consisted of high-dose corticosteroids combined with either mycophenolate mofetil (MMF) or cyclophosphamide.
Compared with standard therapy alone, belimumab increased the complete renal response and the primary efficacy renal response at 2 years. With voclosporin, complete response was nearly doubled, and there was marked increased in partial response at 1 year, compared with standard therapy alone.
Neither drug appeared to increase the adverse-event rate or the rate of discontinuations, compared with standard therapy, although the FDA did add a black box warning regarding the possible risk for serious infections and malignancies with voclosporin use.
“There is a very large unmet need for the treatment of lupus nephritis,” Chris Phillips, MD, of Paducah (Ky.) Rheumatology said in an interview.
“A very large percentage of patients who do not achieve complete remission on traditional treatments have side effects or contraindications to these treatments, so we’ve needed new ones for sure,” he stressed.
The ICER authors made it clear that there is considerable uncertainty as to how short-term assessment of each of the two drugs’ performance might translate into meaningful long-term outcomes for patients, especially given that SLE is a lifelong illness.
On the other hand, “there are a lot of attributes for both of these new drugs that suggest there is potential for kidney benefit over time,” Brad Rovin, MD, professor of medicine and pathology at the Ohio State University Wexner Medical Center, Columbus, said in an interview.
For example, data from the BLISS-LN study, reported by Dr. Rovin during a meeting last year, suggest that belimumab reduces the flare rate and appears to stabilize kidney function over time, compared with standard therapy alone.
“BLISS-LN was 2 years long, so it gave us an opportunity to look at kidney function over a longer period of time than most of our prior trials in lupus nephritis,” he explained.
“The stabilization of kidney function is important, because it suggests that belimumab has a kidney protective effect, while a decrease in lupus nephritis flares is also important, because each time the disease flares, you can accumulate chronic tissue damage, which can eventually cause end-stage renal disease [ESRD],” he said.
Dr. Rovin also pointed out that the BLISS-LN trial results indicate that patients who achieve a urine protein level less than 700 mg/d after the first year of treatment do very well on long-term follow-up – another hint that belimumab may have long-term benefits for kidney function.
Voclosporin is a calcineurin inhibitor, which are protective of podocytes. “When you start to lose too many podocytes, the kidney can again progress onto ESRD, so this is again an extra benefit of the calcineurin inhibitors in the context of kidney disease that affects the glomeruli,” he noted.
“So both of these drugs have these interesting attributes that go beyond, or at least are maybe tied to, their immunosuppressive actions, but they do offer some kidney protective effects,” he reaffirmed.
Black patients underrepresented in trials
The ICER authors voiced concern over the fact that individuals most at risk for SLE – mostly Black patients, but also patients of other racial groups – were underrepresented in clinical trials that evaluated both agents.
“We cannot stress enough that the results are highly uncertain due to the small numbers of Black patients in the available clinical trials and the lack of data on differences among subgroups in long-term outcomes,” they stated.
This is not an academic issue, Dr. Phillips pointed out. Responses to both MMF and cyclophosphamide differ among persons of different races, “so it’s not unreasonable to consider that there could be racial differences in treatment responses to both drugs, and these definitely need to be investigated.”
This is not an academic issue, Dr. Phillips said, because there are racial disparities in how patients respond to both MMF and cyclophosphamide – “so it’s not unreasonable to consider that there could be racial differences in treatment responses to both drugs, and these definitely need to be investigated.”
The ICER authors appear to agree. They urged the manufacturers of the two new agents to expand their research to include adequate representation of lupus nephritis patients from Black and other non-White communities.
However, it is somewhat reassuring that the pivotal voclosporin trial enrolled about 30% of Hispanic patients and that about 17% of participants in the BLISS-LN trial were also Hispanic, Dr. Rovin pointed out.
This is important because Hispanic patients can have very aggressive disease, as can Black patients, he noted. There is some evidence to suggest both drugs are effective in aggressive disease.
The ICER also pointed out that the length of time that both drugs can be used prior to tapering of treatment, after which patients receive standard maintenance therapy alone, has yet to be established.
This is important, Dr. Rovin and Dr. Phillips agreed, because calcineurin inhibitors are known to be nephrotoxic, and both drugs are immunosuppressive. At least with respect to voclosporin, there is some cause of concern regarding prolonged use of the drug for patients with kidney disease.
“We don’t want patients to be on an immunosuppressive drug forever if they don’t need to be,” Dr. Rovin emphasized.
“But we are seeing really long-term remission in the setting of other inflammatory diseases, like vasculitis with rituximab. So there is hope that we can achieve the same thing in lupus. If we use drugs that target T cells in the immune system, like voclosporin, or B cells, like belimumab, maybe we can ‘reset’ the immune system and get rid of potentially autoreactive cells that could allow long-lasting disease remission, which is an unanswered question but an intriguing possibility,” he concluded.
Dr. Rovin has served as a consultant for GlaxoSmithKline. Dr. Phillips disclosed no relevant financial relationships.

This is important, Dr. Rovin and Dr. Phillips agreed, because calcineurin inhibitors are known to be nephrotoxic, and both drugs are immunosuppressive. At least with respect to voclosporin, there is some cause of concern regarding prolonged use of the drug for patients with kidney disease.
“We don’t want patients to be on an immunosuppressive drug forever if they don’t need to be,” Dr. Rovin emphasized.
“But we are seeing really long-term remission in the setting of other inflammatory diseases, like vasculitis with rituximab. So there is hope that we can achieve the same thing in lupus. If we use drugs that target T cells in the immune system, like voclosporin, or B cells, like belimumab, maybe we can ‘reset’ the immune system and get rid of potentially autoreactive cells that could allow long-lasting disease remission, which is an unanswered question but an intriguing possibility,” he concluded.

The prices of two new drugs that have been approved by the Food and Drug Administration for the treatment of lupus nephritis are in “reasonable alignment” with the drugs’ estimated benefits for patients with the disease, the Institute for Clinical and Economic Review has determined.
“Both belimumab [Benlysta] and voclosporin [Lupkynis] are important new treatment options,” Steven Pearson, MD, president of ICER, observed in a summary of the report’s findings.
“Despite remaining uncertainty about both treatments’ longer-term outcomes, their estimated net prices appear to be aligned with their anticipated clinical benefits. ... For patients and clinicians to have responsibly priced options specifically indicated for lupus nephritis is a win for patients and the entire health system,” Dr. Pearson added.
The estimated annual price of belimumab is approximately $43,000 per patient; the estimated annual price for voclosporin is approximately $92,000 per patient.
The incremental cost-effectiveness ratio for belimumab is approximately $90,0000 per quality-adjusted life-year; the corresponding value for voclosporin is higher, at approximately $149,000 per QALY, the ICER authors noted.
The report was published by ICER in April 2021.
Large unmet need for treatment of lupus nephritis
In their report, the ICER reviewed belimumab, a parenteral B-lymphocyte inhibitor, as well as voclosporin, an oral calcineurin inhibitor, as initial treatment of patients with lupus nephritis. Lupus nephritis is a serious complication of systemic lupus erythematosus (SLE).
Belimumab was first approved for the treatment of lupus in adults in the United States in March 2011. In April 2019, it was approved for use for the same indication for children aged 5 years and older. The FDA expanded the indication in December 2020 to include adults with active lupus nephritis who are receiving standard therapy.
Voclosporin was approved for the treatment of lupus nephritis in January 2021.
In the pivotal trials for the two agents, each drug was added to standard induction therapy for lupus nephritis, which consisted of high-dose corticosteroids combined with either mycophenolate mofetil (MMF) or cyclophosphamide.
Compared with standard therapy alone, belimumab increased the complete renal response and the primary efficacy renal response at 2 years. With voclosporin, complete response was nearly doubled, and there was marked increased in partial response at 1 year, compared with standard therapy alone.
Neither drug appeared to increase the adverse-event rate or the rate of discontinuations, compared with standard therapy, although the FDA did add a black box warning regarding the possible risk for serious infections and malignancies with voclosporin use.
“There is a very large unmet need for the treatment of lupus nephritis,” Chris Phillips, MD, of Paducah (Ky.) Rheumatology said in an interview.
“A very large percentage of patients who do not achieve complete remission on traditional treatments have side effects or contraindications to these treatments, so we’ve needed new ones for sure,” he stressed.
The ICER authors made it clear that there is considerable uncertainty as to how short-term assessment of each of the two drugs’ performance might translate into meaningful long-term outcomes for patients, especially given that SLE is a lifelong illness.
On the other hand, “there are a lot of attributes for both of these new drugs that suggest there is potential for kidney benefit over time,” Brad Rovin, MD, professor of medicine and pathology at the Ohio State University Wexner Medical Center, Columbus, said in an interview.
For example, data from the BLISS-LN study, reported by Dr. Rovin during a meeting last year, suggest that belimumab reduces the flare rate and appears to stabilize kidney function over time, compared with standard therapy alone.
“BLISS-LN was 2 years long, so it gave us an opportunity to look at kidney function over a longer period of time than most of our prior trials in lupus nephritis,” he explained.
“The stabilization of kidney function is important, because it suggests that belimumab has a kidney protective effect, while a decrease in lupus nephritis flares is also important, because each time the disease flares, you can accumulate chronic tissue damage, which can eventually cause end-stage renal disease [ESRD],” he said.
Dr. Rovin also pointed out that the BLISS-LN trial results indicate that patients who achieve a urine protein level less than 700 mg/d after the first year of treatment do very well on long-term follow-up – another hint that belimumab may have long-term benefits for kidney function.
Voclosporin is a calcineurin inhibitor, which are protective of podocytes. “When you start to lose too many podocytes, the kidney can again progress onto ESRD, so this is again an extra benefit of the calcineurin inhibitors in the context of kidney disease that affects the glomeruli,” he noted.
“So both of these drugs have these interesting attributes that go beyond, or at least are maybe tied to, their immunosuppressive actions, but they do offer some kidney protective effects,” he reaffirmed.
Black patients underrepresented in trials
The ICER authors voiced concern over the fact that individuals most at risk for SLE – mostly Black patients, but also patients of other racial groups – were underrepresented in clinical trials that evaluated both agents.
“We cannot stress enough that the results are highly uncertain due to the small numbers of Black patients in the available clinical trials and the lack of data on differences among subgroups in long-term outcomes,” they stated.
This is not an academic issue, Dr. Phillips pointed out. Responses to both MMF and cyclophosphamide differ among persons of different races, “so it’s not unreasonable to consider that there could be racial differences in treatment responses to both drugs, and these definitely need to be investigated.”

The ICER authors appear to agree. They urged the manufacturers of the two new agents to expand their research to include adequate representation of lupus nephritis patients from Black and other non-White communities.
However, it is somewhat reassuring that the pivotal voclosporin trial enrolled about 30% of Hispanic patients and that about 17% of participants in the BLISS-LN trial were also Hispanic, Dr. Rovin pointed out.
This is important because Hispanic patients can have very aggressive disease, as can Black patients, he noted. There is some evidence to suggest both drugs are effective in aggressive disease.

Boosting the presence of darker skin in rheumatology education
Studies are flagging racial and ethnic disparities in rheumatology training materials, pointing to a need to boost representation of darker skin tones and better educate physicians in evaluating this cohort.
Not enough is known about these disparities in rheumatology education, despite the fact that minorities make up 40% of the population in the United States.
The problem starts with books and references used in medical schools, Lynn McKinley-Grant, MD, immediate past president of the Skin of Color Society and associate professor of dermatology at Howard University, Washington, said in an interview. “In the medical literature there has been a dearth of images in skin of color in all specialties,” she said. With an increased diversity in the U.S. population, there is a need for health care providers to be able to recognize disease patterns in all skin types.” If a physician is training at an institution where there are not many patients of color in the community, the rheumatologists are even more limited in terms of their clinical experience.
This lack of training in diagnosis of disease has serious clinical repercussions, as seen in COVID cases, Dr. McKinley-Grant noted. “You end up not being able to recognize early erythema, jaundice, anemia, or hypoxemia because those conditions are a different color or pattern in the darker skin types. This can lead to errors in treatment, diagnosis, and medical care, resulting in increased morbidity and mortality.”
Studies point to education gaps
A team of researchers from Washington University in St. Louis called attention to this issue at the American College of Rhematology’s Convergence 2020 conference.
“Patients of color with lupus are especially vulnerable as they often carry a greater disease burden, yet studies show that individuals with darker skin tones are underrepresented in medical educational materials,” Vijay Kannuthurai, MD, and colleagues wrote in their study abstract. The team surveyed 132 providers in St. Louis, Mo., on their confidence in evaluating any rash, and rashes in patients with lupus and varied skin tones.
Participating clinicians, mostly rheumatologists, dermatologists, or internists, had a higher confidence level in diagnosing any rash versus lupus rashes, but were considerably less confident in diagnosing lupus rash on darker skin, compared with those on fair skin. This represents “a disparity between provider confidence and the patient population lupus traditionally affects,” the investigators concluded.
Another recent study found evidence of disparities in clinical education resources. “The lack of dark skin representation among rheumatology educational materials contributes to the implicit bias and structural racism present in medical education by promoting White-only models of disease,” lead author Adrienne Strait, a medical student at the University of California, San Francisco, said in an interview. “Given that rheumatic diseases disproportionately impact racial and ethnic minorities, we felt it was important to examine the representation of these groups within rheumatology training resources.”
She and her colleagues gathered images of rheumatic diseases from four major databases: the American College of Rheumatology’s Image Library, UpToDate, the New England Journal of Medicine Images in Clinical Medicine and Clinical Cases filtered by “Rheumatology,” and the 9th edition of Kelley’s Textbook of Rheumatology. They used Fitzpatrick’s skin phototypes to independently code images depicting skin as “light” (skin types I-IV), “dark” (skin types V-VI), or “indeterminate,” focusing on systemic lupus erythematosus (SLE) and rheumatoid arthritis, two conditions with a known connection to racial and ethnic health disparities.
Taking into account the high incidence of sarcoidosis and SLE in Black patients when compared with White patients, the investigators did a secondary analysis that excluded these cases.
Among 1,043 patient images studied, just 13.4% represented dark skin, compared with 84% that represented light skin. More than 2% represented an indeterminate skin color. Comparing dark-skin representation in the clinical images and SLE images with the representation of Asian, Native American, and Black individuals in the United States and within lupus cases nationally, the investigators found significant underrepresentation of dark skin.
Only 4.2% of RA images had dark-skin representation, making RA one of the diseases with the lowest representation in the study, along with juvenile idiopathic arthritis, the spondyloarthropathies, and Kawasaki disease. “Representation of dark skin in SLE was also lower than the proportion of Black individuals in SLE studies,” the investigators noted. Overall, representation of dark skin in SLE images was just 22.6%. Sarcoidosis comparatively had the largest representation of dark-skin images (69.6%, n = 32).
“Excluding sarcoidosis and SLE images, the overall representation of dark skin was 9.4% (n = 84), which was significantly lower than the proportion of Asian, Native American, and Black individuals within the U.S. Census population,” according to Ms. Strait and her associates. UpToDate contained the largest proportion of images of dark skin respective to other databases, whereas Kelley’s Textbook had the smallest.
Actionable steps
Many physicians are willing to improve upon their skills in identifying conditions on darker skin, as the study by Dr. Kannuthurai and associates suggests. Overall, 93% of the survey’s participants wanted to learn more about rashes in patients of color. “Future educational interventions may help practitioners improve their confidence when diagnosing rashes in lupus patients” with darker skin, they suggested.
Ms. Strait and her colleagues recommended a series of actionable steps to improve diversity and equity of dark skin tone representation in rheumatology curricula.
Editors of educational resources, for example, should make image diversity a priority for those diseases that are most commonly associated with cutaneous manifestations, such as SLE, vasculitis, inflammatory myopathies, systemic sclerosis, sarcoidosis, and psoriasis. They also called for educators in academic rheumatology programs to collaborate to improve diversity in resources used at the undergraduate and graduate medical education level.
Efforts should take place at the local, regional, and national level to publicly discuss and educate clinicians about rheumatic diseases in individuals of color. Speakers at rheumatology conferences should strive to educate learners about presentations of rheumatic diseases in individuals of color. The ACR in the meantime could establish a task force to enhance racial and ethnic diversity in their image library and other published resources.
“These steps may improve provider recognition and diagnosis of rheumatic disease manifestations in skin of color, which may in turn reduce health disparities among racial and ethnic minority groups,” Ms. Strait said.
Beth L. Jonas, MD, chair of the ACR’s Committee on Rheumatology Training and Workforce Issues, called the findings of this study “timely and important.” The researchers highlighted a deficiency in rheumatology training materials that needs addressing, she said in an interview. “I definitely agree that ACR needs to be mindful of this. There’s no doubt that we need to take these recommendations and move along these lines.”
The ACR took a first step in 2020 with the creation of a diversity, equity, and inclusion committee. “We are undergoing a college-wide look at what we do, with an eye toward inclusion. There is a strong interest in addressing health disparities and being an equitable and inclusive community of rheumatology health care professionals,” said Dr. Jonas, chief of the University of North Carolina at Chapel Hill’s division of rheumatology, allergy, and immunology.
The American Academy of Dermatology is also working to improve the image library with images of disease in skin of color. “Everyone’s jumping on this now,” Dr. McKinley-Grant observed. The medical profession can’t afford not to. It’s a life-threatening issue when rheumatoid arthritis and other diseases in people of color aren’t diagnosed early and correctly, she added.
Technologies seek to reduce bias
While many organizations are taking steps to improve representation of darker skin images, VisualDx has taken the lead on this, she said. “They’ve been doing this for years now. There are over 14,000 images of disease in skin of color, including all the rheumatologic diseases. There’s a mobile app and desktop decision support system, and it is very popular. A majority of medical schools have this as a library resource, and hospital systems license it for EHR integration.” Doctors can also get it individually. This enables them to share images and handouts of a diagnosis and select images of patients of color, said Dr. McKinley-Grant, who uses the VisualDx smartphone app DermExpert, which is an app for nondermatologists that features an image library of skin lesions, including darker-skin images.
ProjectIMPACT, powered by VisualDx, is another effort to support reducing health care bias in darker skin. The project is a collaboration between the New England Journal of Medicine Group and the Skin Of Color Society. According to Dr. McKinley-Grant, the organizers are building awareness of the importance of reducing the educational and clinical gaps in diagnosing patients of color and trying to get students and educators to pledge to take meaningful steps and to have real-world impact.
This isn’t just exclusive to dermatology and rheumatology – it involves all medical specialties, she stressed.
ProjectIMPACT isn’t just a resource for physicians, she continued. Librarians can also use it to develop more resources on skin of color.
The Skin Of Color Society and VisualDx have also partnered with the NEJM Group to develop a comprehensive virtual series on the impact of skin color and ethnicity on clinical research. The four-part series addresses structural racism and racial bias in medicine, hair disorders in people of color, pigmentary disorders, keloids, COVID-19 comorbidities, and cutaneous manifestations of systemic diseases in children and adults.
Nuances of recognizing disease
As a medical student, Dr. McKinley-Grant said she was fortunate to attend the Albert Schweitzer Hospital in Lambarene, Gabon, on a fellowship. For 3 months, she gained a wealth of experience examining only African patients with brown skin.
In her other training in medicine, “I’ve been at institutions with diverse populations, in Boston, New York, and Washington,” learning more about all different skin pigments.
This type of training should be more widely available, especially now, with COVID-19 producing new manifestations of skin lesions, she emphasized. Such efforts involve a diversification of images physicians are being trained on so that they can recognize the same disease in a person of color.
“Doctors have to be able to recognize different colors, different shades of brown and shades of white. Not all white skin is the same color,” she noted. In looking at a rash or lesion, “you have to learn how to discern differences in the background color of the skin, which is determined by melanin in the skin (Fitzpatrick skin types I-VI) and by what’s going on in the blood, such as how much oxygen and hemoglobin the patient has in their blood.” Inflammation and infection (erythema) will appear more violaceous in IV-VI skin types, for example.
At the University of North Carolina at Chapel Hill, a group of students and faculty have created a dermatology image library to address the deficiency in the availability of images for teaching purposes. “Our medical students recognized the gap and started this,” Dr. Jonas said. Julie Mervak, MD, assistant professor of dermatology, is spearheading this effort, with students Linnea Westerkam and Anuj Pranav Sanghvi.
“I understand that others around the country are working on similar initiatives,” Dr. Jonas said.

Many physicians are willing to improve upon their skills in identifying conditions on darker skin, as the study by Dr. Kannuthurai and associates suggests. Overall, 93% of the survey’s participants wanted to learn more about rashes in patients of color. “Future educational interventions may help practitioners improve their confidence when diagnosing rashes in lupus patients” with darker skin, they suggested.
Ms. Strait and her colleagues recommended a series of actionable steps to improve diversity and equity of dark skin tone representation in rheumatology curricula.
Editors of educational resources, for example, should make image diversity a priority for those diseases that are most commonly associated with cutaneous manifestations, such as SLE, vasculitis, inflammatory myopathies, systemic sclerosis, sarcoidosis, and psoriasis. They also called for educators in academic rheumatology programs to collaborate to improve diversity in resources used at the undergraduate and graduate medical education level.
Efforts should take place at the local, regional, and national level to publicly discuss and educate clinicians about rheumatic diseases in individuals of color. Speakers at rheumatology conferences should strive to educate learners about presentations of rheumatic diseases in individuals of color. The ACR in the meantime could establish a task force to enhance racial and ethnic diversity in their image library and other published resources.
“These steps may improve provider recognition and diagnosis of rheumatic disease manifestations in skin of color, which may in turn reduce health disparities among racial and ethnic minority groups,” Ms. Strait said.
Beth L. Jonas, MD, chair of the ACR’s Committee on Rheumatology Training and Workforce Issues, called the findings of this study “timely and important.” The researchers highlighted a deficiency in rheumatology training materials that needs addressing, she said in an interview. “I definitely agree that ACR needs to be mindful of this. There’s no doubt that we need to take these recommendations and move along these lines.”
The ACR took a first step in 2020 with the creation of a diversity, equity, and inclusion committee. “We are undergoing a college-wide look at what we do, with an eye toward inclusion. There is a strong interest in addressing health disparities and being an equitable and inclusive community of rheumatology health care professionals,” said Dr. Jonas, chief of the University of North Carolina at Chapel Hill’s division of rheumatology, allergy, and immunology.
The American Academy of Dermatology is also working to improve the image library with images of disease in skin of color. “Everyone’s jumping on this now,” Dr. McKinley-Grant observed. The medical profession can’t afford not to. It’s a life-threatening issue when rheumatoid arthritis and other diseases in people of color aren’t diagnosed early and correctly, she added.
Technologies seek to reduce bias
While many organizations are taking steps to improve representation of darker skin images, VisualDx has taken the lead on this, she said. “They’ve been doing this for years now. There are over 14,000 images of disease in skin of color, including all the rheumatologic diseases. There’s a mobile app and desktop decision support system, and it is very popular. A majority of medical schools have this as a library resource, and hospital systems license it for EHR integration.” Doctors can also get it individually. This enables them to share images and handouts of a diagnosis and select images of patients of color, said Dr. McKinley-Grant, who uses the VisualDx smartphone app DermExpert, which is an app for nondermatologists that features an image library of skin lesions, including darker-skin images.
ProjectIMPACT, powered by VisualDx, is another effort to support reducing health care bias in darker skin. The project is a collaboration between the New England Journal of Medicine Group and the Skin Of Color Society. According to Dr. McKinley-Grant, the organizers are building awareness of the importance of reducing the educational and clinical gaps in diagnosing patients of color and trying to get students and educators to pledge to take meaningful steps and to have real-world impact.
This isn’t just exclusive to dermatology and rheumatology – it involves all medical specialties, she stressed.
ProjectIMPACT isn’t just a resource for physicians, she continued. Librarians can also use it to develop more resources on skin of color.
The Skin Of Color Society and VisualDx have also partnered with the NEJM Group to develop a comprehensive virtual series on the impact of skin color and ethnicity on clinical research. The four-part series addresses structural racism and racial bias in medicine, hair disorders in people of color, pigmentary disorders, keloids, COVID-19 comorbidities, and cutaneous manifestations of systemic diseases in children and adults.
Nuances of recognizing disease
As a medical student, Dr. McKinley-Grant said she was fortunate to attend the Albert Schweitzer Hospital in Lambarene, Gabon, on a fellowship. For 3 months, she gained a wealth of experience examining only African patients with brown skin.
In her other training in medicine, “I’ve been at institutions with diverse populations, in Boston, New York, and Washington,” learning more about all different skin pigments.
This type of training should be more widely available, especially now, with COVID-19 producing new manifestations of skin lesions, she emphasized. Such efforts involve a diversification of images physicians are being trained on so that they can recognize the same disease in a person of color.
“Doctors have to be able to recognize different colors, different shades of brown and shades of white. Not all white skin is the same color,” she noted. In looking at a rash or lesion, “you have to learn how to discern differences in the background color of the skin, which is determined by melanin in the skin (Fitzpatrick skin types I-VI) and by what’s going on in the blood, such as how much oxygen and hemoglobin the patient has in their blood.” Inflammation and infection (erythema) will appear more violaceous in IV-VI skin types, for example.
At the University of North Carolina at Chapel Hill, a group of students and faculty have created a dermatology image library to address the deficiency in the availability of images for teaching purposes. “Our medical students recognized the gap and started this,” Dr. Jonas said. Julie Mervak, MD, assistant professor of dermatology, is spearheading this effort, with students Linnea Westerkam and Anuj Pranav Sanghvi.
“I understand that others around the country are working on similar initiatives,” Dr. Jonas said.

Most patients with chronic inflammatory diseases have sufficient response to COVID-19 vaccination
Glucocorticoids and B-cell–depleting therapies are trouble spots
Although most patients with chronic inflammatory diseases mounted immune responses after two doses of mRNA-based COVID-19 vaccines, glucocorticoids and B-cell–depleting therapies markedly reduced the response, according to a recently published preprint of a new study.
The study, published on MedRxiv and not yet peer reviewed, involved a prospective look at 133 patients with chronic inflammatory disease (CID) and 53 patients with healthy immune systems at Washington University, St. Louis, and the University of California, San Francisco. It is regarded as the largest and most detailed study yet in how vaccines perform in people with immune-mediated inflammatory disease. The patients were enrolled between December 2020 and March 2021, and the most common diseases were inflammatory bowel disease (32%), rheumatoid arthritis (29%), spondyloarthritis (15%), and systemic lupus erythematosus (11%).
A ‘modest’ reduction in antibody response
Senior author Alfred Kim, MD, PhD, of the department of medicine at Washington University, said the overall results so far are encouraging.
“Most patients with an autoimmune disease that are on immunosuppression can mount antibody responses,” he said. “We’re seeing the majority of our subjects respond.”
The immune-healthy controls and most of the patients with CID had a robust immune response against the spike protein, although the CID group had a mean reduction in antibody titers that was three times lower than the controls (P = .0092). The CID group similarly had a 2.7-fold reduction in preventing neutralization, or halting the virus’ ability to infect (P < .0001), researchers reported.
This reduction in response is “modest,” he said.
“Is the level of reduction going to be detrimental for protection? Time will tell,” he said, adding that researchers anticipate that it won’t have a critical effect on protection because responses tended to be within the range of the immunocompetent controls, who themselves had wildly varied antibody titers across a 20-fold range. “ ‘Optimal’ isn’t necessarily the same as ‘sufficient.’ ”
Type of medication has big impact on antibody titers
But there was a wide variety of effects on the immune response depending on the medication. Glucorticoids resulted in a response that was 10 times lower than the immune-healthy controls, as well as fewer circulating plasmablasts after vaccination. Researchers found that 98% of controls were seropositive for antibody, compared with 92% of those with CID who were not taking prednisone, and 65% of CID patients on prednisone (P = .0006 and .0115, respectively). Prevention of neutralization of the virus was similarly reduced in those groups, compared with the controls. Dr. Kim noted this was a small sample size, with about 15 patients. These effects were seen regardless of the dose.
“We would’ve anticipated this would have been dose dependent, so this was a little bit surprising,” Dr. Kim said.
B-cell–depleting therapies, such as rituximab (Rituxan) and ocrelizumab (Ocrevus), reduced antibody titers by 36 times, compared with controls (P < .0001), with a similar reduction in preventing infection (P = .0066), the researchers found. The reduction in antibody titers was the most pronounced among those who had received B-cell–depleting therapies within the previous 6 months. Dr. Kim noted this was a small sample size, with about 10 patients.
CID study subjects taking an antimetabolite, including methotrexate, had an average of a two- to threefold reduction in antibody titers and in neutralization (P = .0006). This reduction was greatest with methotrexate, researchers found (P = .0027).
JAK inhibitors also significantly reduced antibody titers (P = .0066), but the reduction in neutralization of the virus was not significant. In addition, researchers found a reduction in antibody titers, the prevention of viral infection, and circulating plasmablasts among those on tumor necrosis factor (TNF) inhibitors, compared with controls, but these were insignificant statistically except for virus neutralization.
Dr. Kim said he hopes the glucocorticoid data spur physicians to try harder to wean patients off the drugs, when possible, in keeping with recommendations already in place.
“The general culture in rheumatology has been very lax about the need to reduce glucocorticoids,” he said. “This reinvigorates that call.” Questions about possible drug holidays from glucocorticoids remain, regarding how long a holiday would be needed, he said. He noted that many patients on glucocorticoids nonetheless mounted responses.
Those on B-cell–depleting therapies present a “much more difficult” question, he said. Some patients possibly could wait a bit longer than their normal, every-6-month schedule, but it’s an individual decision, he said. Since a booster of influenza vaccine has been found to enhance the response even within the 6-month window among ocrelizumab patients, a booster of COVID-19 vaccine might also help, although this remains to be studied.
The study group has already increased its sample size and is looking at adverse reactions and long-term immune responses, Dr. Kim said.
Encouraging, rather than discouraging, results
Leonard Calabrese, DO, professor of medicine at the Cleveland Clinic in Ohio, said the findings shouldn’t discourage clinicians from encouraging vaccination.
“There’s still a preponderance of people who will develop a robust antibody vaccine response,” he said.
He cautioned that the findings look only at antibodies to the spike protein and at plasmablasts. The reduction in these titers is “of concern,” he said, but “we don’t really know with certainty what are the effects of these drugs, and these data are on the overall biologic protective effect of the vaccine. There’s much more to a vaccine response than anti–spike protein and plasmablasts,” including cell-mediated immune response.
For an individual patient, the findings “mean a lot,” he said.
“I think that people who are on significant prednisone and B-cell–depleting agents, I think you have to share with them that there’s a reasonable chance that you’re not going to be making a response similar to healthy people,” he said. “Thus, even with your vaccine, we’re not going to cut you loose to do things that are violating social distancing and group settings. … Should you be hugging your grandchildren if you’re a rituximab vaccine recipient? I think I would wait until we have a little bit more data.”
Kevin Winthrop, MD, MPH, professor of ophthalmology at Oregon Health & Science University, Portland, where he studies vaccinations in the immunocompromised, said that glucocorticoids tend to have little effect on vaccinations generally at low doses.
When effects are seen they can be difficult to interpret, he said.
“It’s hard to extricate that from the effect of the underlying disease,” he said. The drug can be a proxy for worse disease control.
Although it’s a small study, it’s reassuring that overall the responses were similar to healthy controls.
For B-cell–depleting therapies, his usual guidance is to not give vaccine until a patient is at least 3 months out from their last dose, and not to restart until at least 2 weeks after vaccination.
“It’s not surprising that some of these DMARDs [disease-modifying antirheumatic drugs] do negatively affect vaccine response, particularly B-cell–depletion therapy. We need to do some studies to find a way to overcome that, or optimize delivery of the vaccine.”
Dr. Kim reported participating in consulting, advisory board, or speaker’s bureau for Alexion, Aurinia, Annexon Biosciences, Exagen Diagnostics, and GlaxoSmithKline, and receiving funding under a sponsored research agreement unrelated to the data in the paper from GlaxoSmithKline. Dr. Winthrop reported receiving consulting fees from Pfizer, AbbVie, UCB, Eli Lilly, Galapagos, GlaxoSmithKline, Roche, Gilead, Bristol-Myers Squibb, Regeneron, Sanofi, AstraZeneca, Novartis, and research grants from Bristol-Myers Squibb and Pfizer.

FROM MEDRXIV
Black patients with cutaneous sarcoidosis may have more systemic and CV disease
according to a retrospective chart review of patients seen at Massachusetts General Hospital and Brigham and Women’s Hospital, both in Boston.
Black patients were also significantly more likely to have two or more organs involved and have higher rates of cardiac involvement, the latter of which is associated with worse prognosis. “Our data suggest there may be substantial variations in organ involvement between racial groups of patients presenting with cutaneous sarcoidosis,” said medical student Kylee Kus, a medical student at Oakland University, Auburn Hills, Mich., who presented the findings with Bina Kassamali, a medical student at Harvard University, Boston, at the annual Skin of Color Society scientific symposium.
Sotonye Imadojemu, MD, MBE; Avery LeChance, MD, MPH; and Ruth Anne Vleugels, MD, MPH, MBA; of Brigham and Women’s Hospital, are cosenior authors of the abstract.
The researchers identified 111 patients who were diagnosed with cutaneous sarcoidosis over a 20-year period (January 2000–December 2019), 50 of whom presented without established extracutaneous disease. They examined the charts of these 50 patients for whether subsequent work-up revealed systemic disease.
Of the 50 patients, 9 were Black. Seven of these nine patients (77.8%), were found to have systemic involvement, compared with 14 of 41 (46.3%) non-Black patients – a 31.5% higher probability (P < .05). One-third of the nine Black patients were found to have disease in one organ, and 44.4% in two or more organs. In non-Black patients, these rates were 12.2% and 34.1%, respectively.
Cardiovascular involvement was not found in any of the non-Black patients who had extracutaneous disease, but was found in 29% of the Black patients with extracutaneous disease, a statistically significant difference.
Black patients are known to be at higher risk for sarcoidosis than non-Black patients, and because “there is an association between cardiac sarcoid involvement and poor prognosis largely due to manifestations such as heart block, arrhythmias, and heart failure ... the study helps demonstrate how this organ involvement can disproportionately affect the Black population,” Ms. Kassamali said in an interview after the meeting.
A separate, recently published analysis of data from the same patient population examined the work-ups that patients received after a dermatologist’s diagnosis of sarcoidosis and found that patients with no previous systemic work-up were subsequently assessed for cardiac involvement in only 58.3% of cases. Assessment for pulmonary and ocular disease was completed more than 90% of the time.
“Crucial testing for cardiac involvement fell short,” Dr. Imadojemu, of the department of dermatology, Brigham and Women’s Hospital, and coinvestigators wrote in the research letter.
“Because the cutaneous manifestations of sarcoidosis often present at disease onset, dermatologists may be the first physicians to diagnose a patient with sarcoidosis,” they wrote. “As such, dermatologists are often responsible for initiating the appropriate evaluation of patients with sarcoidosis.”
Pulmonary involvement occurs in nearly all cases of sarcoidosis, while ocular and cardiac disease develop in approximately 25% and 10% of patients, respectively. Cardiac sarcoidosis is usually asymptomatic and accounts for 13%-25% of sarcoidosis-related deaths in the United States, they wrote.
An electrocardiogram is the appropriate initial screening tool and “is warranted in all patients with sarcoidosis,” they advised.

One-third of the nine Black patients were found to have disease in one organ, and 44.4% in two or more organs. In non-Black patients, these rates were 12.2% and 34.1%, respectively.
Cardiovascular involvement was not found in any of the non-Black patients who had extracutaneous disease, but was found in 29% of the Black patients with extracutaneous disease, a statistically significant difference.
Black patients are known to be at higher risk for sarcoidosis than non-Black patients, and because “there is an association between cardiac sarcoid involvement and poor prognosis largely due to manifestations such as heart block, arrhythmias, and heart failure ... the study helps demonstrate how this organ involvement can disproportionately affect the Black population,” Ms. Kassamali said in an interview after the meeting.
A separate, recently published analysis of data from the same patient population examined the work-ups that patients received after a dermatologist’s diagnosis of sarcoidosis and found that patients with no previous systemic work-up were subsequently assessed for cardiac involvement in only 58.3% of cases. Assessment for pulmonary and ocular disease was completed more than 90% of the time.
“Crucial testing for cardiac involvement fell short,” Dr. Imadojemu, of the department of dermatology, Brigham and Women’s Hospital, and coinvestigators wrote in the research letter.
“Because the cutaneous manifestations of sarcoidosis often present at disease onset, dermatologists may be the first physicians to diagnose a patient with sarcoidosis,” they wrote. “As such, dermatologists are often responsible for initiating the appropriate evaluation of patients with sarcoidosis.”
Pulmonary involvement occurs in nearly all cases of sarcoidosis, while ocular and cardiac disease develop in approximately 25% and 10% of patients, respectively. Cardiac sarcoidosis is usually asymptomatic and accounts for 13%-25% of sarcoidosis-related deaths in the United States, they wrote.
An electrocardiogram is the appropriate initial screening tool and “is warranted in all patients with sarcoidosis,” they advised.
according to a retrospective chart review of patients seen at Massachusetts General Hospital and Brigham and Women’s Hospital, both in Boston.
Black patients were also significantly more likely to have two or more organs involved and have higher rates of cardiac involvement, the latter of which is associated with worse prognosis. “Our data suggest there may be substantial variations in organ involvement between racial groups of patients presenting with cutaneous sarcoidosis,” said medical student Kylee Kus, a medical student at Oakland University, Auburn Hills, Mich., who presented the findings with Bina Kassamali, a medical student at Harvard University, Boston, at the annual Skin of Color Society scientific symposium.

The researchers identified 111 patients who were diagnosed with cutaneous sarcoidosis over a 20-year period (January 2000–December 2019), 50 of whom presented without established extracutaneous disease. They examined the charts of these 50 patients for whether subsequent work-up revealed systemic disease.
Of the 50 patients, 9 were Black. Seven of these nine patients (77.8%), were found to have systemic involvement, compared with 14 of 41 (46.3%) non-Black patients – a 31.5% higher probability (P < .05).

Renal, cardiovascular damage may develop in mild SLE despite treatment
Patients with mild to moderate systemic lupus erythematosus (SLE) disease activity without any past history of organ damage may still progress to develop damage, particularly renal and cardiovascular disease, or death, in a relatively short amount of follow-up time, new research suggests.
The study, published in Lupus Science & Medicine, also showed that use of hydroxychloroquine lowered the risk of death and renal damage, whereas use of NSAIDs or any antihypertensives increased risk for cardiovascular damage.
“The impact of irreversible organ system damage in the prognosis of SLE remains a major concern because patients who develop damage are more likely to accrue additional damage and die,” wrote Deanna Hill, PhD, of GlaxoSmithKline, Collegeville, Pa., and coauthors, including Michelle Petri, MD, of Johns Hopkins University, Baltimore.
The researchers followed 1,168 adult patients with SLE from the Johns Hopkins Lupus Cohort, most of whom were women, 55% of whom were White and 39% of whom were Black. They divided the follow-up period into three parts: first year after enrollment into the cohort as background, second year as observation period, and the remainder of follow-up time until damage occurred, death, or end of available data.
At baseline, 55% of patients had mild to moderate disease, defined as an adjusted mean SELENA-SLEDAI (Safety of Estrogens in Lupus Erythematosus National Assessment SLE Disease Activity Index) score of less than 3. Patients had a median adjusted mean SELENA-SLEDAI score of 3 in the first year, which dropped to 2 in the observation period and remained there during the rest of follow-up.
Eight percent of patients died during the follow-up period. Each one-unit mean increase in SELENA-SLEDAI score during the 1-year observation period was associated with a significant 22% increase in the subsequent risk of death during the subsequent follow-up period (95% confidence interval, 1.13-1.32; P < .001).
Three-quarters of patients (n = 888) had no history of damage at the start of the follow-up period, but 39% of these patients had developed damage by the end of follow-up. Among patients without prior damage, a single-unit increase in disease activity score was also associated with a 9% increase in the risk of accruing organ damage (95% CI, 1.04-1.15; P < .001) after adjustment for confounding factors.
While only 3% of patients – most of whom were women – developed renal damage during the follow-up period, a one-unit increase in disease activity score was associated with a 24% increase in the risk of renal damage (95% CI, 1.08-1.42, P = .003).
The researchers found that 7% of patients developed cardiovascular damage during the follow-up period, and each one-unit increase in disease activity score was associated with a 17% increase in the risk of cardiovascular damage (95% CI, 1.07-1.29; P < .001).
“The findings in this analysis corroborate the influence of disease activity for renal and cardiovascular damage accrual and death and also extend the findings to patients with SLE and mild to moderate disease activity,” the authors wrote.
Impact of treatment
Researchers also examined the effect of treatments, and found that patients treated with hydroxychloroquine during the 1-year observation period had a 54% lower risk of subsequent death (95% CI, 0.29-0.72; P < .05) and a 70% lower risk of renal damage (95% CI, 0.13-0.68, P < .05). However, patients prescribed NSAIDs had a 66% higher risk of cardiovascular damage, while those who used any antihypertensive had an 81% higher risk of cardiovascular damage.
“This may suggest that the known cardiovascular risk of NSAIDs in the general population is also applicable to patients with SLE and highlights the importance of assessing cardiovascular risk in this patient population,” the authors wrote.
Smoking affected the risk of death: Smokers were 74% more likely to die during the follow-up period than were nonsmokers.
There were no significant differences between different ethnicities in the study. While White patients generally had lower disease activity overall, there was no significant differences in the risk of death or organ damage with ethnicity.
