In head-to-head trial, two biologics differ markedly for control of psoriasis
with other biologics, according to data from two simultaneously published trials, one of which was a head-to-head comparison with ustekinumab.
In the head-to-head trial called BE VIVID, which included a placebo arm, there was a large advantage of bimekizumab over ustekinumab, a biologic that targets IL-12 and IL-23 and is approved for treating psoriasis, for both coprimary endpoints, according to a multinational group of investigators led by Kristian Reich, MD, PhD, professor of dermatology at the University Medical Center, Hamburg-Eppendorf, Germany.
The proportion of patients with skin clearance was not only greater but faster, “with responses observed after one dose,” Dr. Reich and coinvestigators reported.
The data from the BE VIVID trial was published simultaneously with the BE READY trial, which was placebo-controlled but did not include an active comparator.
Evaluated at week 16, the coprimary endpoints in both studies were skin clearance as measured by a Psoriasis Area Severity Index greater than 90% (PASI 90) and Investigators Global Assessment (IGA) score of 0 (clear) or 1 (almost clear).
In BE VIVID, 567 patients were randomized in 11 countries, including the United States. The dose of bimekizumab was 320 mg administered subcutaneously every 4 weeks. In a randomization scheme of 4:2:1, half as many patients (163) were randomized to ustekinumab (Stelara), which was administered in weight-based dosing of 45 mg or 90 mg at enrollment, at 4 weeks, and then every 12 weeks. The placebo arm had 83 patients. All were switched to bimekizumab at 16 weeks.
At week 16, PASI 90 was achieved in 85% of patients randomized to bimekizumab, compared with 50% of patients randomized to ustekinumab (P < .0001). The rate in the placebo group was 5%.
The bimekizumab advantage for an IGA response of 0 or 1 was of similar magnitude, relative to ustekinumab (84% vs. 53%; P < .0001) and placebo (5%). All secondary efficacy endpoints, such as PASI 90 at week 12 (85% vs. 44%) and PASI 100 at week 16 (59% vs. 21%), favored bimekizumab over ustekinumab.
In the BE READY trial, which evaluated the same dose and schedule of bimekizumab, the rates of PASI 90 at week 16 were 91% and 1% (P < .0001) for the experimental arm and placebo, respectively. The proportion of patients with an IGA score of 0 or 1 were 93% and 1% (P < .0001), respectively.
In BE READY, patients who achieved PASI 90 at week 16 were reallocated to receive bimekizumab every 4 weeks, bimekizumab every 8 weeks (also 320 mg), or placebo. Both schedules of bimekizumab maintained responses through week 56, according to the authors, led by Kenneth B. Gordon, MD, professor and chair of dermatology, Medical College of Wisconsin, Milwaukee.
In both trials, safety was evaluated over the first 16 weeks as well as over a subsequent maintenance period, which extended to 52 weeks in BE VIVID and 56 weeks in BE READY. For bimekizumab, oral candidiasis was the most common treatment-related adverse event. In BE VIVID, this adverse event was reported in 9% of bimekizumab patients, compared with 0% of either the ustekinumab or placebo groups, up to week 16. Out to week 52, the rates were 15% in the bimekizumab group and 1% in the ustekinumab group.
In the BE READY trial, the rates of oral candidiasis were 6% and 0% for bimekizumab and placebo, respectively, through week 16. Over the maintenance periods, the rates were 9% and 11% for the every-8-week and every-4-week doses, respectively.
Discontinuation for adverse events was not higher on bimekizumab than placebo in either trial, nor was the proportion of serious treatment-emergent adverse events.
Nevertheless, the potential for adverse events was a key part of the discussion regarding the future role of bimekizumab, if approved, in an editorial that accompanied the publication of these studies.
“Bimekizumab might be our most effective biologic for psoriasis yet,” coauthors, William W. Huang, MD, PhD, associate professor of dermatology, and Steven R. Feldman, MD, PhD, professor of dermatology, both at Wake Forest University, Winston-Salem, NC, wrote in the editorial. “If the goal of psoriasis treatment is complete clearance, bimekizumab seems like a good option from an efficacy perspective.”
However, they noted that other IL-17 blockers, like secukinumab (Cosentyx) and brodalumab (Siliq), have been associated with risks, including the development of inflammatory bowel disease. In addition to the oral candidiasis seen in the BE VIVID and BE READY trials, they cautioned that other issues might arise with longer follow-up and greater numbers of patients exposed to this therapy.
In an interview, Dr. Feldman said adequately informed patients might be willing to accept these risks for the potential of greater efficacy, but he emphasized the need for appropriate warnings and education.
“We have a lot of very good treatments that offer patients an excellent chance of an excellent outcome – treatments that have been around and in use in large numbers of people for years,” Dr. Feldman said. “Unless the doctor and patient felt strongly about the need to use this new, perhaps more potent option, I would be personally inclined to use treatment with well-established safety profiles first.”
The senior author of the BE VIVID trial, Mark Lebwohl, MD, dean for clinical therapeutics and professor of dermatology, at the Icahn School of Medicine at Mount Sinai, New York, disagreed. He acknowledged that other agents targeting IL-17 have been associated with IBD, but risk of IBD is already elevated in patients with psoriasis and the risk appears to be lower with bimekizumab relative to prior agents in this class.
“Bimekizumab has now been studied in thousands of patients over several years. We can say with support from a sizable amount of data that IBD is very uncommon,” he said. While oral candidiasis is associated with bimekizumab, it is “easy to treat.”
Asked specifically if he will consider using bimekizumab as a first-line agent in psoriasis patients who are candidates for a biologic, Dr. Lebwohl said he would. Based on the evidence that this agent is more effective than other options and has manageable side effects, he believes it will be an important new treatment option.

Patients with early arthritis may need tailored treatments
Patients with early, undifferentiated arthritis may benefit from milder or stronger treatments, depending on the number of their risk factors for developing rheumatoid arthritis, researchers say.
If the finding is borne out by further research, clinicians could consider treating some of these patients with hydroxychloroquine, steroids, or nonsteroidal anti-inflammatory drugs (NSAIDs) rather than methotrexate, said Pascal de Jong, MD, PhD, a rheumatologist at Erasmus Medical Center in Rotterdam, the Netherlands.
“Maybe those patients with fewer risk factors should get less intensive treatment,” he said in an interview. The study by de Jong and colleagues was published online Jan. 23 in Rheumatology.
The European Alliance of Associations for Rheumatology recommends starting treatment with methotrexate for patients who are at risk for persistent arthritis, which it says is “factually synonymous” with rheumatoid arthritis.
But these recommendations are based on studies involving patients with established rheumatoid arthritis, Dr. de Jong said.
In an earlier study, he and his colleagues found that hydroxychloroquine can be just as effective as methotrexate for patients newly diagnosed with rheumatoid arthritis who don’t have autoantibodies. This led them to wonder whether their findings might apply to some subgroups of patients with early arthritis.
As an initial test of this idea, they identified 130 patients from the Rotterdam Early Arthritis Cohort (tREACH) trial who had at least one swollen joint but who did meet the diagnostic criteria for rheumatoid arthritis.
They sorted the patients into groups on the basis of the number of risk factors for persistent arthritis. The risk factors were autoantibody positivity (rheumatoid factor and/or anticitrullinated protein antibody), polyarthritis (more than four swollen joints), erosive disease, and elevations in levels of acute-phase reactants.
Thirty-one patients had none of these risk factors, 66 patients had one risk factor, and the remaining 33 patients had at least two risk factors.
After 2 years of follow-up, 74% of the patients who had had no risk factors had recovered from their arthritis and had not taken disease-modifying antirheumatic drugs (DMARDs) for at least 6 months (DMARD-free remission). Among the patients who had had one risk factor, 48% achieved DMARD-free remission. Among those who had had two risk factors, 45% achieved DMARD-free remission. The differences between the group that had had no risk factors and the other two groups were statistically significant (P < .05).
The researchers found that those patients who had been experiencing their symptoms for fewer than 6 months were more likely to achieve disease-free remission.
They also sorted patients into different groups on the basis of the treatments they received. One group of 30 comprised all patients who had been initially treated with methotrexate and included patients who had also received other drugs. One group of 40 received hydroxychloroquine initially, and one group of 60 comprised patients who had received no DMARDs initially and included those who had received NSAIDs or glucocorticoids.
There was no statistically significant difference in DMARD-free remission rates among the treatment groups. However, among those patients who were not treated initially with DMARDs, the chance of sustaining DMARD-free remission for more than a year was lower in comparison with the patients who received methotrexate initially (odds ratio, 4.28; 95% confidence interval, 1.34-13.72; P < .05).
Those patients who had fewer baseline risk factors were more likely to have their medication dosages tapered, and they were at lower risk for flares. Patients with more risk factors were more likely to require an intensificiation of treatment, such as with the use of biologicals.
Methotrexate is more likely to cause side effects such as nausea, fatigue, and hair loss than hydroxychloroquine, Dr. de Jong said. “If the medication is better tolerated, it also influences the compliance of the patient,” he said.
The study could help rheumatologists determine which patients need the most aggressive treatment, agreed Kevin Deane, MD, PhD, associate professor of medicine, division of rheumatology, the University of Colorado, Aurora.
“That’s a common clinical problem,” he said. “Somebody comes in with sort of mild arthritis, and you don’t quite know what it is yet.”
But he added that more research is needed to understand what treatment works best for those patients whose arthritis has not yet been differentiated. Primary care physicians who suspect inflammatory arthritis should refer their patients to rheumatologists and should test for rheumatoid factors and anticyclic citrullinated peptide, Dr. Deane said.
The authors and Dr. Deane have disclosed no relevant financial relationships.

Tofacitinib for RA misses the mark in safety study
Daily treatment with tofacitinib (Xeljanz) led to more malignancies and adverse cardiovascular events in older rheumatoid arthritis patients compared with treatment with a tumor necrosis factor (TNF) inhibitor, according to the partial results of a safety study announced last week by Pfizer.
The postmarketing study known as ORAL Surveillance began in 2014 to evaluate the safety of the Janus kinase (JAK) inhibitor tofacitinib compared to a TNF inhibitor in RA patients 50 years of age or older with at least one additional cardiovascular risk factor. Its 4,362 participants were randomized to either daily doses of 5 mg (n = 1,455) or 10 mg (n = 1,456) of tofacitinib or the TNFi (n = 1,451), which was adalimumab for patients in the United States, Canada, and Puerto Rico, and etanercept elsewhere. During analysis, adverse events were pooled for all patients on tofacitinib.
Overall, 135 patients developed major adverse cardiovascular events (MACE) and 164 developed malignancies – excluding nonmelanoma skin cancer. The incidence of adjudicated malignancies was significantly higher in the tofacitinib group, compared with the TNFi group (1.13 vs. 0.77 per 100 person-years; hazard ratio, 1.48; 95% confidence interval, 1.04-2.09). The rate of MACE was also higher in the combined tofacitinib group (0.98 vs. 0.73 per 100 person-years; HR, 1.33; 95% CI, 0.91-1.94). Both rates for tofacitinib did not meet the trial’s noninferiority criteria.
Among the patients on tofacitinib, the most reported MACE was myocardial infarction and the most reported malignancy was lung cancer. Study participants with noted risk factors – including older age and smoking – were more likely to experience adverse events.
In February 2019, patients in the 10-mg tofacitinib group were switched to the 5-mg because of a safety signal indicating increased risk of pulmonary embolism and death.
Tofacitinib was approved for RA in November 2012, though concerns about serious side effects had been noted during clinical trials and a boxed warning was ultimately added to the drug’s label. Tofacitinib is also approved for adults with active psoriatic arthritis, adults with moderately to severely active ulcerative colitis, and patients aged 2 years or older with active polyarticular course juvenile idiopathic arthritis. Other JAK inhibitors such as baricitinib and upadacitinib have been approved for RA in the interim as well, though the higher dose of baricitinib was rejected in committee because of safety concerns and both their boxes also warn against infections, thrombosis, and cancer.
A postmarketing safety study on baricitinib is expected to be completed in 2025.
The full results of the ORAL Surveillance study – which should address safety regarding pulmonary embolism and mortality, as well as efficacy data – have not yet been released. “Pfizer is working with the [FDA] and other regulatory agencies to review the full results and analyses as they become available,” the press release said.

Guselkumab maintains psoriasis efficacy long after discontinuation
Fully half of patients with moderate to severe psoriasis who achieve complete clearance after their first four doses of guselkumab (Tremfya) continue to maintain a PASI 90 response nearly 6 months after withdrawal of the biologic, according to a post hoc analysis of the pivotal phase 3 VOYAGE 2 trial.
“That’s impressive maintenance of efficacy,” said Curdin Conrad, MD, who presented the data at the virtual annual congress of the European Academy of Dermatology and Venereology.
“These findings are reassuring when you have to interrupt guselkumab therapy: For example, due to acute infection, pregnancy, or surgery. But it might also help when considering in the future a flexible dosing interval, particularly for patients who had complete clearance,” added Dr. Conrad, professor of dermatology and head of the polyclinic and the Center of Excellence for Psoriasis at Lausanne (Switzerland) University Hospital.
The intriguing implication from VOYAGE 2 that guselkumab might lend itself to flexible dosing featuring lengthy drug-free intervals is being prospectively examined in the ongoing phase 3b GUIDE trial. This is a double-blind, placebo-controlled trial including 888 French and German patients with moderate to severe psoriasis and a study hypothesis that those who have a Psoriasis Area and Severity Index score of 0 at weeks 20 and 28 in response to on-label dosing – the so-called ‘super responders’ – will maintain disease control until week 68 if their dosing is reduced to 100 mg of guselkumab every 16 weeks instead of the standard 8-week intervals.
Dr. Conrad reported that in VOYAGE 2, 106 patients on standard-dose guselkumab who had a PASI score of 0 at weeks 20 and 28 were randomized to discontinue the interleukin-23 inhibitor after receiving their fourth dose at week 20. It took 25 weeks for 50% of them to lose their PASI 90 response as defined by regression to a PASI score of 1 or greater. Using a less stringent definition of maintenance of efficacy, the super responders’ median time off guselkumab until reaching a PASI score of 3 or more was 30.7 weeks, with a median of 35.4 weeks to a PASI score of 5 or more.
In addition, 34 other VOYAGE 2 participants who were almost clear on guselkumab at weeks 20 and 28, with a PASI score of more than 0 but less than 1, were randomized to guselkumab withdrawal after their week-20 dose. Median time to loss of their PASI 90 response was shorter than that of the super responders – not surprising since their mean PASI score when the biologic was halted was 0.5, rather than 0 as for the super responders. But Dr. Conrad said the maintenance of response was still impressive: A median of 16.2 weeks to reach a PASI score of 1 or more, 27.2 weeks for a PASI 3, and 33.7 weeks for a PASI score of 5.
He reported receiving research funding from and serving as a scientific adviser to Janssen, the study sponsor, as well as to more than a dozen other pharmaceutical companies.

FROM THE EADV CONGRESS
Deucravacitinib offers biologic-like psoriasis efficacy in oral form
and a range of other chronic inflammatory diseases, Bruce E. Strober, MD, PhD, said at MedscapeLive’s annual Las Vegas Dermatology Seminar, held virtually this year.
Deucravacitinib solely blocks tyrosine kinase 2 (TYK2) signaling without touching Janus kinase (JAK) 1, 2, or 3. In so doing, it inhibits several cytokines important for inflammation: interleukin-12, IL-13, and interferon-alpha and -beta. Yet it doesn’t affect the numerous pathways mediated by JAKs 1-3, many of which relate to growth and development of cell lineages, including production of erythropoietin, thrombopoietin, granulocyte-macrophage colony-stimulating factor, prolactin, growth hormone, and leptin. These deucravacitinib characteristics should translate into fewer off-target side effects than with oral JAK inhibitors.
“The promise of TYK2 inhibition that’s brought to you by deucravacitinib is there will be no laboratory monitoring and the effects will be narrow in blocking inflammation,” said Dr. Strober, a dermatologist at Yale University, New Haven, Conn., and in private practice in Cromwell, Conn.
He highlighted the positive results of a randomized, phase 2, dose-ranging study conducted in 267 patients with moderate or severe plaque psoriasis. Participants had an average baseline Psoriasis Area and Severity Index (PASI) score of 19, with a Dermatology Life Quality Index score of about 12. At the top dose of 12 mg once daily, 75% of patients achieved a PASI 75 response at week 12, and 44% reached a PASI 90, as did 69% and 44%, respectively, who were on deucravacitinib at 3 mg twice daily. Those are collective efficacy numbers similar to adalimumab (Humira) or ustekinumab (Stelara).
Deucravacitinib may provide efficacy “like one of our second-tier biological therapies, yet it will be oral,” Dr. Strober commented.
Importantly, no laboratory abnormalities were detected in this trial. Only mild side effects were documented, most prominently acne, which occurred in dose-dependent fashion in 2% of patients on 3 mg of deucravacitinib twice daily and 4% at 12 mg once daily.
“The treatment of the acne that is elicited by this drug is yet to be fully described, but I’m sure we’ll learn the best approaches, given that acne is in our wheel house,” the dermatologist added.
Bristol-Myers Squibb has announced positive results from the pivotal phase 3 POETYK PSO-1 trial. Deucravacitinib at 6 mg once daily met both of its coprimary efficacy endpoints in the study, which included 666 patients with moderate to severe psoriasis. The TYK 2 inhibitor demonstrated superiority to both placebo and oral apremilast (Otezla) at week 16. The company said the safety profile was consistent with the phase 2 results, and that the full details of the phase 3 trial will be presented next year at a major medical meeting.
In addition, positive phase 2 results were reported for deucravacitinib in the treatment of psoriatic arthritis in a randomized trial presented at the fall 2020 meeting of the American College of Rheumatology. Deucravacitinib is also under study for lupus and inflammatory bowel disease.

Osteoporosis prevalence in PsA similar to general population
The rates of osteopenia and osteoporosis among individuals with psoriatic arthritis are comparable to those seen in the general population, research suggests.
The cohort study, published in Arthritis Care & Research, also found that clinicians are likely to refer patients for bone mineral density (BMD) testing based on osteoporosis risk factors or psoriatic arthritis disease severity markers.
Timothy S.H. Kwok, MD, of the University of Toronto, and coauthors wrote that previous research suggested a possible link between psoriatic arthritis and osteoporosis or osteopenia. However, no cohort studies appear to have examined this association.
The study involved 201 individuals with psoriatic arthritis attending a single specialist clinic, who were enrolled in a longitudinal study of psoriatic arthritis (PsA) and who were also referred for BMD testing with dual-energy x-ray absorptiometry.
Of these participants, 13% had a BMD in the osteoporotic range, 45% were in the osteopenic range, and 42% were in the normal range for BMD. The prevalence of osteoporosis observed in the general population aged 50 or above, observed in an earlier large prospective study, ranged from 7% to 16%, and osteopenia ranged from 27% to 46%.
“Our study suggests that patients with PsA have similar BMDs compared to the general population,” the authors wrote.
Researchers did note the suggestion that patients with polyarthritis had lower BMDs over time. Because of the small number of events, this did not achieve statistical significance, but “this relationship warrants further research, given that multiple cohort studies have independently demonstrated polyarticular onset of disease predicting clinical deformities and erosive disease in PsA,” they wrote.
They also saw that patients with increased body mass index had a significant 21% lower odds of having a BMD in the osteoporotic range, while those using biologics had a significant 83% lower odds.
Among participants with BMD scores in the osteopenic or osteoporotic range, these scores were seen in the lumbar spine in 63% of measurements, the femoral neck in 88%, and the total hip in 39%. Mean T-scores for the lumbar spine were –0.30±0.32, and for the femoral neck were –1.10±1.04 and the total hip, –0.45±0.42.
The study also examined what factors were associated with referral for BMD testing. They found that increasing age, menopause, elevated acute phase reactants, or use of biologics, methotrexate, and systemic glucocorticoids were associated with a higher likelihood of undergoing BMD testing.
Noting that the latest Canadian clinical practice guidelines on BMD testing advise that age, menopause, and use of systemic glucocorticoids use are risk factors that should prompt testing, the authors suggested clinicians were using a combination of traditional osteoporosis risk factors and markers of psoriatic disease severity to underpin their decision to refer.
However, they commented that none of the factors associated with a higher likelihood of having a BMD test were actually associated with lower BMD scores.
“This suggests that clinicians may be over-screening patients with PsA for osteopenia/osteoporosis, as they do not appear to be at baseline higher risk for lower BMD scores than the general population,” they wrote. “This is of importance, as there are currently no formal recommendations with regards to the optimal interval or time to commence BMD testing within the recent major PsA guidelines.”
The study was supported by a grant from the Krembil Foundation. No conflicts of interest were declared.

Because of the small number of events, this did not achieve statistical significance, but “this relationship warrants further research, given that multiple cohort studies have independently demonstrated polyarticular onset of disease predicting clinical deformities and erosive disease in PsA,” they wrote.
They also saw that patients with increased body mass index had a significant 21% lower odds of having a BMD in the osteoporotic range, while those using biologics had a significant 83% lower odds.
Among participants with BMD scores in the osteopenic or osteoporotic range, these scores were seen in the lumbar spine in 63% of measurements, the femoral neck in 88%, and the total hip in 39%. Mean T-scores for the lumbar spine were –0.30±0.32, and for the femoral neck were –1.10±1.04 and the total hip, –0.45±0.42.
The study also examined what factors were associated with referral for BMD testing. They found that increasing age, menopause, elevated acute phase reactants, or use of biologics, methotrexate, and systemic glucocorticoids were associated with a higher likelihood of undergoing BMD testing.
Noting that the latest Canadian clinical practice guidelines on BMD testing advise that age, menopause, and use of systemic glucocorticoids use are risk factors that should prompt testing, the authors suggested clinicians were using a combination of traditional osteoporosis risk factors and markers of psoriatic disease severity to underpin their decision to refer.
However, they commented that none of the factors associated with a higher likelihood of having a BMD test were actually associated with lower BMD scores.
“This suggests that clinicians may be over-screening patients with PsA for osteopenia/osteoporosis, as they do not appear to be at baseline higher risk for lower BMD scores than the general population,” they wrote. “This is of importance, as there are currently no formal recommendations with regards to the optimal interval or time to commence BMD testing within the recent major PsA guidelines.”

The rates of osteopenia and osteoporosis among individuals with psoriatic arthritis are comparable to those seen in the general population, research suggests.
The cohort study, published in Arthritis Care & Research, also found that clinicians are likely to refer patients for bone mineral density (BMD) testing based on osteoporosis risk factors or psoriatic arthritis disease severity markers.
Timothy S.H. Kwok, MD, of the University of Toronto, and coauthors wrote that previous research suggested a possible link between psoriatic arthritis and osteoporosis or osteopenia. However, no cohort studies appear to have examined this association.
The study involved 201 individuals with psoriatic arthritis attending a single specialist clinic, who were enrolled in a longitudinal study of psoriatic arthritis (PsA) and who were also referred for BMD testing with dual-energy x-ray absorptiometry.
Of these participants, 13% had a BMD in the osteoporotic range, 45% were in the osteopenic range, and 42% were in the normal range for BMD. The prevalence of osteoporosis observed in the general population aged 50 or above, observed in an earlier large prospective study, ranged from 7% to 16%, and osteopenia ranged from 27% to 46%.

EULAR recommendations define strategies to improve adherence in RMDs
Clinicians who care for patients with rheumatic and musculoskeletal diseases (RMDs) can now refer to a new set of strategies and points to consider from a European League Against Rheumatism (EULAR) task force in building a patient-centered approach to improve adherence to treatments.
Nonadherence to treatments is concerning given that 30%-80% of patients who have RMDs are thought to not follow a recommended treatment plan according to their physicians’ instructions, according to first author Valentin Ritschl of the Medical University of Vienna and colleagues.
“The problem of poor adherence is addressed in some EULAR recommendations/points to consider on the management of specific health conditions or on the role of professionals,” Mr. Ritschl said in an interview. “However, all these recommendations focus on limited aspects of nonadherence and do not cover the multifaceted nature of this phenomenon.”
Mr. Ritschl and colleagues conducted an extensive systematic literature review, the results of which they presented to a task force consisting of a panel of international experts hailing from 12 different countries. The task force included rheumatologists and other health professionals in rheumatology, as well as patient representatives.
The collaboration resulted in investigators crafting a definition of adherence in addition to drafting four overarching principles and nine points to consider, which were published Dec. 18 in Annals of the Rheumatic Diseases.
They defined adherence as “the extent to which a person’s behavior corresponds with the agreed prescription, of pharmacological or nonpharmacological treatments, by a health care provider.”
The four overarching principles emphasize the following concepts: that adherence affects outcomes in people who have RMDs; the importance of shared decision-making, with the understanding that the adherence describes the patient’s behavior “following an agreed prescription”; that numerous factors can affect adherence; and the notion of adherence being a dynamic process that, consequently, requires continuous evaluation.
Among the nine points to consider, Mr. Ritschl and coauthors encouraged all health care providers involved in caring for RMD patients to assume responsibility for promoting adherence. Practitioners should also strive to create an ongoing, open dialogue to discuss adherence, especially in cases in which the patient’s RMD is not well controlled. The patient-centered recommendations include taking into account the patient’s goals and preferences because these greatly contribute to the patient’s ability to adhere to any medication regimen. Another arm of that exploration also requires the medical professional to evaluate any circumstances that could bear a negative effect on the patient’s adherence – whether it be medication access issues related to cost or availability, or functional challenges such as memory, motivation, or complexity of the medication regimen.
Mr. Ritschl believed the task force’s recommendations will add value and help improve overall outcomes in RMD population management.
“Until today, there are no recommendations or points to consider developed in order to support our patients to be adherent to the agreed treatment plan,” he said. “In our project/initiative, we therefore developed for the first time points to consider to detect, assess, and manage nonadherence in people with RMDs.”
Additionally, the recommendations offer some strategic insights to help improve clinical trials because the deleterious effects of nonadherence also affect study results.
Looking ahead, Mr. Ritschl said randomized, controlled trials are necessary to test strategies that might improve adherence. He strongly emphasized the importance of designing future research studies that are heavily patient centered and effective for shared decision-making.
The project was funded by EULAR. Mr. Ritschl reported having no disclosures, but many of his coauthors reported financial relationships with pharmaceutical companies.

FROM ANNALS OF THE RHEUMATIC DISEASES
COVID-19 vaccines: Safe for immunocompromised patients?
Coronavirus vaccines have become a reality, as they are now being approved and authorized for use in a growing number of countries including the United States. The U.S. Food and Drug Administration has just issued emergency authorization for the use of the COVID-19 vaccine produced by Pfizer and BioNTech. Close behind is the vaccine developed by Moderna, which has also applied to the FDA for emergency authorization.
The efficacy of a two-dose administration of the vaccine has been pegged at 95.0%, and the FDA has said that the 95% credible interval for the vaccine efficacy was 90.3%-97.6%. But as with many initial clinical trials, whether for drugs or vaccines, not all populations were represented in the trial cohort, including individuals who are immunocompromised. At the current time, it is largely unknown how safe or effective the vaccine may be in this large population, many of whom are at high risk for serious COVID-19 complications.
At a special session held during the recent annual meeting of the American Society of Hematology, Anthony Fauci, MD, the nation’s leading infectious disease expert, said that individuals with compromised immune systems, whether because of chemotherapy or a bone marrow transplant, should plan to be vaccinated when the opportunity arises.
In response to a question from ASH President Stephanie J. Lee, MD, of the Fred Hutchinson Cancer Center, Seattle, Dr. Fauci emphasized that, despite being excluded from clinical trials, this population should get vaccinated. “I think we should recommend that they get vaccinated,” he said. “I mean, it is clear that, if you are on immunosuppressive agents, history tells us that you’re not going to have as robust a response as if you had an intact immune system that was not being compromised. But some degree of immunity is better than no degree of immunity.”
That does seem to be the consensus among experts who spoke in interviews: that as long as these are not live attenuated vaccines, they hold no specific risk to an immunocompromised patient, other than any factors specific to the individual that could be a contraindication.
“Patients, family members, friends, and work contacts should be encouraged to receive the vaccine,” said William Stohl, MD, PhD, chief of the division of rheumatology at the University of Southern California, Los Angeles. “Clinicians should advise patients to obtain the vaccine sooner rather than later.”
Kevin C. Wang, MD, PhD, of the department of dermatology at Stanford (Calif.) University, agreed. “I am 100% with Dr. Fauci. Everyone should get the vaccine, even if it may not be as effective,” he said. “I would treat it exactly like the flu vaccines that we recommend folks get every year.”
Dr. Wang noted that he couldn’t think of any contraindications unless the immunosuppressed patients have a history of severe allergic reactions to prior vaccinations. “But I would even say patients with history of cancer, upon recommendation of their oncologists, are likely to be suitable candidates for the vaccine,” he added. “I would say clinicians should approach counseling the same way they counsel patients for the flu vaccine, and as far as I know, there are no concerns for systemic drugs commonly used in dermatology patients.”
However, guidance has not yet been issued from either the FDA or the Centers for Disease Control and Prevention regarding the use of the vaccine in immunocompromised individuals. Given the lack of data, the FDA has said that “it will be something that providers will need to consider on an individual basis,” and that individuals should consult with physicians to weigh the potential benefits and potential risks.
The CDC’s Advisory Committee on Immunization Practices has said that clinicians need more guidance on whether to use the vaccine in pregnant or breastfeeding women, the immunocompromised, or those who have a history of allergies. The CDC itself has not yet released its formal guidance on vaccine use.
COVID-19 vaccines
Vaccines typically require years of research and testing before reaching the clinic, but this year researchers embarked on a global effort to develop safe and effective coronavirus vaccines in record time. Both the Pfizer/BioNTech and Moderna vaccines have only a few months of phase 3 clinical trial data, so much remains unknown about them, including their duration of effect and any long-term safety signals. In addition to excluding immunocompromised individuals, the clinical trials did not include children or pregnant women, so data are lacking for several population subgroups.
But these will not be the only vaccines available, as the pipeline is already becoming crowded. U.S. clinical trial data from a vaccine jointly being developed by Oxford-AstraZeneca, could potentially be ready, along with a request for FDA emergency use authorization, by late January 2021.
In addition, China and Russia have released vaccines, and there are currently 61 vaccines being investigated in clinical trials and at least 85 preclinical products under active investigation.
The vaccine candidates are using both conventional and novel mechanisms of action to elicit an immune response in patients. Conventional methods include attenuated inactivated (killed) virus and recombinant viral protein vaccines to develop immunity. Novel approaches include replication-deficient, adenovirus vector-based vaccines that contain the viral protein, and mRNA-based vaccines, such as the Pfizer and Moderna vaccines, that encode for a SARS-CoV-2 spike protein.
“The special vaccine concern for immunocompromised individuals is introduction of a live virus,” Dr. Stohl said. “Neither the Moderna nor Pfizer vaccines are live viruses, so there should be no special contraindication for such individuals.”
Live vaccine should be avoided in immunocompromised patients, and currently, live SARS-CoV-2 vaccines are only being developed in India and Turkey.
It is not unusual for vaccine trials to begin with cohorts that exclude participants with various health conditions, including those who are immunocompromised. These groups are generally then evaluated in phase 4 trials, or postmarketing surveillance. While the precise number of immunosuppressed adults in the United States is not known, the numbers are believed to be rising because of increased life expectancy among immunosuppressed adults as a result of advances in treatment and new and wider indications for therapies that can affect the immune system.
According to data from the 2013 National Health Interview Survey, an estimated 2.7% of U.S. adults are immunosuppressed. This population covers a broad array of health conditions and medical specialties; people living with inflammatory or autoimmune conditions, such as inflammatory rheumatic diseases (rheumatoid arthritis, axial spondyloarthritis, lupus); inflammatory bowel disease (Crohn’s disease and ulcerative colitis); psoriasis; multiple sclerosis; organ transplant recipients; patients undergoing chemotherapy; and life-long immunosuppression attributable to HIV infection.
As the vaccines begin to roll out and become available, how should clinicians advise their patients, in the absence of any clinical trial data?
Risk vs. benefit
Gilaad Kaplan, MD, MPH, a gastroenterologist and professor of medicine at the University of Calgary (Alta.), noted that the inflammatory bowel disease (IBD) community has dealt with tremendous anxiety during the pandemic because many are immunocompromised because of the medications they use to treat their disease.
“For example, many patients with IBD are on biologics like anti-TNF [tumor necrosis factor] therapies, which are also used in other immune-mediated inflammatory diseases such as rheumatoid arthritis,” he said. “Understandably, individuals with IBD on immunosuppressive medications are concerned about the risk of severe complications due to COVID-19.”
The entire IBD community, along with the world, celebrated the announcement that multiple vaccines are protective against SARS-CoV-2, he noted. “Vaccines offer the potential to reduce the spread of COVID-19, allowing society to revert back to normalcy,” Dr. Kaplan said. “Moreover, for vulnerable populations, including those who are immunocompromised, vaccines offer the potential to directly protect them from the morbidity and mortality associated with COVID-19.”
That said, even though the news of vaccines are extremely promising, some cautions must be raised regarding their use in immunocompromised populations, such as persons with IBD. “The current trials, to my knowledge, did not include immunocompromised individuals and thus, we can only extrapolate from what we know from other trials of different vaccines,” he explained. “We know from prior vaccines studies that the immune response following vaccination is less robust in those who are immunocompromised as compared to a healthy control population.”
Dr. Kaplan also pointed to recent reports of allergic reactions that have been reported in healthy individuals. “We don’t know whether side effects, like allergic reactions, may be different in unstudied populations,” he said. “Thus, the medical and scientific community should prioritize clinical studies of safety and effectiveness of COVID-19 vaccines in immunocompromised populations.”
So, what does this mean for an individual with an immune-mediated inflammatory disease like Crohn’s disease or ulcerative colitis who is immunocompromised? Dr. Kaplan explained that it is a balance between the potential harm of being infected with COVID-19 and the uncertainty of receiving a vaccine in an understudied population. For those who are highly susceptible to dying from COVID-19, such as an older adult with IBD, or someone who faces high exposure, such as a health care worker, the potential protection of the vaccine greatly outweighs the uncertainty.
“However, for individuals who are at otherwise lower risk – for example, young and able to work from home – then waiting a few extra months for postmarketing surveillance studies in immunocompromised populations may be a reasonable approach, as long as these individuals are taking great care to avoid infection,” he said.
No waiting needed
Joel M. Gelfand, MD, MSCE, professor of dermatology and epidemiology at the University of Pennsylvania, Philadelphia, feels that the newly approved vaccine should be safe for most of his patients.
“Patients with psoriatic disease should get the mRNA-based COVID-19 vaccine as soon as possible based on eligibility as determined by the CDC and local public health officials,” he said. “It is not a live vaccine, and therefore patients on biologics or other immune-modulating or immune-suppressing treatment can receive it.”
However, the impact of psoriasis treatment on immune response to the mRNA-based vaccines is not known. Dr. Gelfand noted that, extrapolating from the vaccine literature, there is some evidence that methotrexate reduces response to the influenza vaccine. “However, the clinical significance of this finding is not clear,” he said. “Since the mRNA vaccine needs to be taken twice, a few weeks apart, I do not recommend interrupting or delaying treatment for psoriatic disease while undergoing vaccination for COVID-19.”
Given the reports of allergic reactions, he added that it is advisable for patients with a history of life-threatening allergic reactions such as anaphylaxis or who have been advised to carry an epinephrine autoinjector, to talk with their health care provider to determine if COVID-19 vaccination is medically appropriate.
The National Psoriasis Foundation has issued guidance on COVID-19, explained Steven R. Feldman, MD, PhD, professor of dermatology, pathology, and social sciences & health policy at Wake Forest University, Winston-Salem, N.C., who is also a member of the committee that is working on those guidelines and keeping them up to date. “We are in the process of updating the guidelines with information on COVID vaccines,” he said.
He agreed that there are no contraindications for psoriasis patients to receive the vaccine, regardless of whether they are on immunosuppressive treatment, even though definitive data are lacking. “Fortunately, there’s a lot of good data coming out of Italy that patients with psoriasis on biologics do not appear to be at increased risk of getting COVID or of having worse outcomes from COVID,” he said.
Patients are going to ask about the vaccines, and when counseling them, clinicians should discuss the available data, the residual uncertainty, and patients’ concerns should be considered, Dr. Feldman explained. “There may be some concern that steroids and cyclosporine would reduce the effectiveness of vaccines, but there is no concern that any of the drugs would cause increased risk from nonlive vaccines.”
He added that there is evidence that “patients on biologics who receive nonlive vaccines do develop antibody responses and are immunized.”
Boosting efficacy
Even prior to making their announcement, the American College of Rheumatology had said that they would endorse the vaccine for all patients, explained rheumatologist Brett Smith, DO, from Blount Memorial Physicians Group and East Tennessee Children’s Hospital, Alcoa. “The vaccine is safe for all patients, but the problem may be that it’s not as effective,” he said. “But we don’t know that because it hasn’t been tested.”
With other vaccines, biologic medicines are held for 2 weeks before and afterwards, to get the best response. “But some patients don’t want to stop the medication,” Dr. Smith said. “They are afraid that their symptoms will return.”
As for counseling patients as to whether they should receive this vaccine, he explained that he typically doesn’t try to sway patients one way or another until they are really high risk. “When I counsel, it really depends on the individual situation. And for this vaccine, we have to be open to the fact that many people have already made up their mind.”
There are a lot of questions regarding the vaccine. One is the short time frame of development. “Vaccines typically take 6-10 years to come on the market, and this one is now available after a 3-month study,” Dr. Smith said. “Some have already decided that it’s too new for them.”
The process is also new, and patients need to understand that it doesn’t contain an active virus and “you can’t catch coronavirus from it.”
Dr. Smith also explained that, because the vaccine may be less effective in a person using biologic therapies, there is currently no information available on repeat vaccination. “These are all unanswered questions,” he said. “If the antibodies wane in a short time, can we be revaccinated and in what time frame? We just don’t know that yet.”
Marcelo Bonomi, MD, a medical oncologist from The Ohio State University Comprehensive Cancer Center, Columbus, explained that one way to ensure a more optimal response to the vaccine would be to wait until the patient has finished chemotherapy.* “The vaccine can be offered at that time, and in the meantime, they can take other steps to avoid infection,” he said. “If they are very immunosuppressed, it isn’t worth trying to give the vaccine.”
Cancer patients should be encouraged to stay as healthy as possible, and to wear masks and social distance. “It’s a comprehensive approach. Eat healthy, avoid alcohol and tobacco, and exercise. [These things] will help boost the immune system,” Dr. Bonomi said. “Family members should be encouraged to get vaccinated, which will help them avoid infection and exposing the patient.”
Jim Boonyaratanakornkit, MD, PhD, an infectious disease specialist who cares for cancer patients at the Fred Hutchinson Cancer Research Center, agreed. “Giving a vaccine right after a transplant is a futile endeavor,” he said. “We need to wait 6 months to have an immune response.”
He pointed out there may be a continuing higher number of cases, with high levels peaking in Washington in February and March. “Close friends and family should be vaccinated if possible,” he said, “which will help interrupt transmission.”
The vaccines are using new platforms that are totally different, and there is no clear data as to how long the antibodies will persist. “We know that they last for at least 4 months,” said Dr. Boonyaratanakornkit. “We don’t know what level of antibody will protect them from COVID-19 infection. Current studies are being conducted, but we don’t have that information for anyone yet.”

Both the Pfizer/BioNTech and Moderna vaccines have only a few months of phase 3 clinical trial data, so much remains unknown about them, including their duration of effect and any long-term safety signals. In addition to excluding immunocompromised individuals, the clinical trials did not include children or pregnant women, so data are lacking for several population subgroups.
But these will not be the only vaccines available, as the pipeline is already becoming crowded. U.S. clinical trial data from a vaccine jointly being developed by Oxford-AstraZeneca, could potentially be ready, along with a request for FDA emergency use authorization, by late January 2021.
In addition, China and Russia have released vaccines, and there are currently 61 vaccines being investigated in clinical trials and at least 85 preclinical products under active investigation.
The vaccine candidates are using both conventional and novel mechanisms of action to elicit an immune response in patients. Conventional methods include attenuated inactivated (killed) virus and recombinant viral protein vaccines to develop immunity. Novel approaches include replication-deficient, adenovirus vector-based vaccines that contain the viral protein, and mRNA-based vaccines, such as the Pfizer and Moderna vaccines, that encode for a SARS-CoV-2 spike protein.
“The special vaccine concern for immunocompromised individuals is introduction of a live virus,” Dr. Stohl said. “Neither the Moderna nor Pfizer vaccines are live viruses, so there should be no special contraindication for such individuals.”
Live vaccine should be avoided in immunocompromised patients, and currently, live SARS-CoV-2 vaccines are only being developed in India and Turkey.
It is not unusual for vaccine trials to begin with cohorts that exclude participants with various health conditions, including those who are immunocompromised. These groups are generally then evaluated in phase 4 trials, or postmarketing surveillance. While the precise number of immunosuppressed adults in the United States is not known, the numbers are believed to be rising because of increased life expectancy among immunosuppressed adults as a result of advances in treatment and new and wider indications for therapies that can affect the immune system.
According to data from the 2013 National Health Interview Survey, an estimated 2.7% of U.S. adults are immunosuppressed. This population covers a broad array of health conditions and medical specialties; people living with inflammatory or autoimmune conditions, such as inflammatory rheumatic diseases (rheumatoid arthritis, axial spondyloarthritis, lupus); inflammatory bowel disease (Crohn’s disease and ulcerative colitis); psoriasis; multiple sclerosis; organ transplant recipients; patients undergoing chemotherapy; and life-long immunosuppression attributable to HIV infection.
As the vaccines begin to roll out and become available, how should clinicians advise their patients, in the absence of any clinical trial data?
Risk vs. benefit
Gilaad Kaplan, MD, MPH, a gastroenterologist and professor of medicine at the University of Calgary (Alta.), noted that the inflammatory bowel disease (IBD) community has dealt with tremendous anxiety during the pandemic because many are immunocompromised because of the medications they use to treat their disease.
“For example, many patients with IBD are on biologics like anti-TNF [tumor necrosis factor] therapies, which are also used in other immune-mediated inflammatory diseases such as rheumatoid arthritis,” he said. “Understandably, individuals with IBD on immunosuppressive medications are concerned about the risk of severe complications due to COVID-19.”
The entire IBD community, along with the world, celebrated the announcement that multiple vaccines are protective against SARS-CoV-2, he noted. “Vaccines offer the potential to reduce the spread of COVID-19, allowing society to revert back to normalcy,” Dr. Kaplan said. “Moreover, for vulnerable populations, including those who are immunocompromised, vaccines offer the potential to directly protect them from the morbidity and mortality associated with COVID-19.”
That said, even though the news of vaccines are extremely promising, some cautions must be raised regarding their use in immunocompromised populations, such as persons with IBD. “The current trials, to my knowledge, did not include immunocompromised individuals and thus, we can only extrapolate from what we know from other trials of different vaccines,” he explained. “We know from prior vaccines studies that the immune response following vaccination is less robust in those who are immunocompromised as compared to a healthy control population.”
Dr. Kaplan also pointed to recent reports of allergic reactions that have been reported in healthy individuals. “We don’t know whether side effects, like allergic reactions, may be different in unstudied populations,” he said. “Thus, the medical and scientific community should prioritize clinical studies of safety and effectiveness of COVID-19 vaccines in immunocompromised populations.”
So, what does this mean for an individual with an immune-mediated inflammatory disease like Crohn’s disease or ulcerative colitis who is immunocompromised? Dr. Kaplan explained that it is a balance between the potential harm of being infected with COVID-19 and the uncertainty of receiving a vaccine in an understudied population. For those who are highly susceptible to dying from COVID-19, such as an older adult with IBD, or someone who faces high exposure, such as a health care worker, the potential protection of the vaccine greatly outweighs the uncertainty.
“However, for individuals who are at otherwise lower risk – for example, young and able to work from home – then waiting a few extra months for postmarketing surveillance studies in immunocompromised populations may be a reasonable approach, as long as these individuals are taking great care to avoid infection,” he said.
No waiting needed
Joel M. Gelfand, MD, MSCE, professor of dermatology and epidemiology at the University of Pennsylvania, Philadelphia, feels that the newly approved vaccine should be safe for most of his patients.
“Patients with psoriatic disease should get the mRNA-based COVID-19 vaccine as soon as possible based on eligibility as determined by the CDC and local public health officials,” he said. “It is not a live vaccine, and therefore patients on biologics or other immune-modulating or immune-suppressing treatment can receive it.”
However, the impact of psoriasis treatment on immune response to the mRNA-based vaccines is not known. Dr. Gelfand noted that, extrapolating from the vaccine literature, there is some evidence that methotrexate reduces response to the influenza vaccine. “However, the clinical significance of this finding is not clear,” he said. “Since the mRNA vaccine needs to be taken twice, a few weeks apart, I do not recommend interrupting or delaying treatment for psoriatic disease while undergoing vaccination for COVID-19.”
Given the reports of allergic reactions, he added that it is advisable for patients with a history of life-threatening allergic reactions such as anaphylaxis or who have been advised to carry an epinephrine autoinjector, to talk with their health care provider to determine if COVID-19 vaccination is medically appropriate.
The National Psoriasis Foundation has issued guidance on COVID-19, explained Steven R. Feldman, MD, PhD, professor of dermatology, pathology, and social sciences & health policy at Wake Forest University, Winston-Salem, N.C., who is also a member of the committee that is working on those guidelines and keeping them up to date. “We are in the process of updating the guidelines with information on COVID vaccines,” he said.
He agreed that there are no contraindications for psoriasis patients to receive the vaccine, regardless of whether they are on immunosuppressive treatment, even though definitive data are lacking. “Fortunately, there’s a lot of good data coming out of Italy that patients with psoriasis on biologics do not appear to be at increased risk of getting COVID or of having worse outcomes from COVID,” he said.
Patients are going to ask about the vaccines, and when counseling them, clinicians should discuss the available data, the residual uncertainty, and patients’ concerns should be considered, Dr. Feldman explained. “There may be some concern that steroids and cyclosporine would reduce the effectiveness of vaccines, but there is no concern that any of the drugs would cause increased risk from nonlive vaccines.”
He added that there is evidence that “patients on biologics who receive nonlive vaccines do develop antibody responses and are immunized.”
Boosting efficacy
Even prior to making their announcement, the American College of Rheumatology had said that they would endorse the vaccine for all patients, explained rheumatologist Brett Smith, DO, from Blount Memorial Physicians Group and East Tennessee Children’s Hospital, Alcoa. “The vaccine is safe for all patients, but the problem may be that it’s not as effective,” he said. “But we don’t know that because it hasn’t been tested.”
With other vaccines, biologic medicines are held for 2 weeks before and afterwards, to get the best response. “But some patients don’t want to stop the medication,” Dr. Smith said. “They are afraid that their symptoms will return.”
As for counseling patients as to whether they should receive this vaccine, he explained that he typically doesn’t try to sway patients one way or another until they are really high risk. “When I counsel, it really depends on the individual situation. And for this vaccine, we have to be open to the fact that many people have already made up their mind.”
There are a lot of questions regarding the vaccine. One is the short time frame of development. “Vaccines typically take 6-10 years to come on the market, and this one is now available after a 3-month study,” Dr. Smith said. “Some have already decided that it’s too new for them.”
The process is also new, and patients need to understand that it doesn’t contain an active virus and “you can’t catch coronavirus from it.”
Dr. Smith also explained that, because the vaccine may be less effective in a person using biologic therapies, there is currently no information available on repeat vaccination. “These are all unanswered questions,” he said. “If the antibodies wane in a short time, can we be revaccinated and in what time frame? We just don’t know that yet.”
Marcelo Bonomi, MD, a medical oncologist from The Ohio State University Comprehensive Cancer Center, Columbus, explained that one way to ensure a more optimal response to the vaccine would be to wait until the patient has finished chemotherapy.* “The vaccine can be offered at that time, and in the meantime, they can take other steps to avoid infection,” he said. “If they are very immunosuppressed, it isn’t worth trying to give the vaccine.”
Cancer patients should be encouraged to stay as healthy as possible, and to wear masks and social distance. “It’s a comprehensive approach. Eat healthy, avoid alcohol and tobacco, and exercise. [These things] will help boost the immune system,” Dr. Bonomi said. “Family members should be encouraged to get vaccinated, which will help them avoid infection and exposing the patient.”
Jim Boonyaratanakornkit, MD, PhD, an infectious disease specialist who cares for cancer patients at the Fred Hutchinson Cancer Research Center, agreed. “Giving a vaccine right after a transplant is a futile endeavor,” he said. “We need to wait 6 months to have an immune response.”
He pointed out there may be a continuing higher number of cases, with high levels peaking in Washington in February and March. “Close friends and family should be vaccinated if possible,” he said, “which will help interrupt transmission.”
The vaccines are using new platforms that are totally different, and there is no clear data as to how long the antibodies will persist. “We know that they last for at least 4 months,” said Dr. Boonyaratanakornkit. “We don’t know what level of antibody will protect them from COVID-19 infection. Current studies are being conducted, but we don’t have that information for anyone yet.”

Coronavirus vaccines have become a reality, as they are now being approved and authorized for use in a growing number of countries including the United States. The U.S. Food and Drug Administration has just issued emergency authorization for the use of the COVID-19 vaccine produced by Pfizer and BioNTech. Close behind is the vaccine developed by Moderna, which has also applied to the FDA for emergency authorization.
The efficacy of a two-dose administration of the vaccine has been pegged at 95.0%, and the FDA has said that the 95% credible interval for the vaccine efficacy was 90.3%-97.6%. But as with many initial clinical trials, whether for drugs or vaccines, not all populations were represented in the trial cohort, including individuals who are immunocompromised. At the current time, it is largely unknown how safe or effective the vaccine may be in this large population, many of whom are at high risk for serious COVID-19 complications.
At a special session held during the recent annual meeting of the American Society of Hematology, Anthony Fauci, MD, the nation’s leading infectious disease expert, said that individuals with compromised immune systems, whether because of chemotherapy or a bone marrow transplant, should plan to be vaccinated when the opportunity arises.
In response to a question from ASH President Stephanie J. Lee, MD, of the Fred Hutchinson Cancer Center, Seattle, Dr. Fauci emphasized that, despite being excluded from clinical trials, this population should get vaccinated. “I think we should recommend that they get vaccinated,” he said. “I mean, it is clear that, if you are on immunosuppressive agents, history tells us that you’re not going to have as robust a response as if you had an intact immune system that was not being compromised. But some degree of immunity is better than no degree of immunity.”
That does seem to be the consensus among experts who spoke in interviews: that as long as these are not live attenuated vaccines, they hold no specific risk to an immunocompromised patient, other than any factors specific to the individual that could be a contraindication.
“Patients, family members, friends, and work contacts should be encouraged to receive the vaccine,” said William Stohl, MD, PhD, chief of the division of rheumatology at the University of Southern California, Los Angeles. “Clinicians should advise patients to obtain the vaccine sooner rather than later.”
Kevin C. Wang, MD, PhD, of the department of dermatology at Stanford (Calif.) University, agreed. “I am 100% with Dr. Fauci. Everyone should get the vaccine, even if it may not be as effective,” he said. “I would treat it exactly like the flu vaccines that we recommend folks get every year.”
Dr. Wang noted that he couldn’t think of any contraindications unless the immunosuppressed patients have a history of severe allergic reactions to prior vaccinations. “But I would even say patients with history of cancer, upon recommendation of their oncologists, are likely to be suitable candidates for the vaccine,” he added. “I would say clinicians should approach counseling the same way they counsel patients for the flu vaccine, and as far as I know, there are no concerns for systemic drugs commonly used in dermatology patients.”
However, guidance has not yet been issued from either the FDA or the Centers for Disease Control and Prevention regarding the use of the vaccine in immunocompromised individuals. Given the lack of data, the FDA has said that “it will be something that providers will need to consider on an individual basis,” and that individuals should consult with physicians to weigh the potential benefits and potential risks.
The CDC’s Advisory Committee on Immunization Practices has said that clinicians need more guidance on whether to use the vaccine in pregnant or breastfeeding women, the immunocompromised, or those who have a history of allergies. The CDC itself has not yet released its formal guidance on vaccine use.

Synovial, skin gene expression differences may explain PsA treatment responses
Differences in gene expression between the skin and synovial tissues of individuals with psoriatic arthritis could explain why treatments targeting proinflammatory mechanisms don’t improve joint symptoms in some patients.
A paper published in Annals of the Rheumatic Diseases presents the results of an observational, open-label study involving 27 patients with active psoriatic arthritis, 18 of whom were treated with anti–tumor necrosis factor (anti-TNF) therapies and 9 with the monoclonal antibody ustekinumab (Stelara). This drug targets the axis of proinflammatory cytokine interleukin-23 and effector cytokine IL-12, which are believed to play an important role both in skin and nail psoriasis, and psoriatic arthritis.
However, while anti–IL-23 antibodies seem to work well to address skin manifestations of psoriasis, they tend to improve joint symptoms only in selected patients.
“The lack of a clear mechanism to explain such divergent responses prompted this study,” said Dr. Alessandra Nerviani, lead author of the study, from the Barts and The London School of Medicine & Dentistry.
Participants also had biopsies taken from the synovium – in particular, from joints that were clinically and ultrasonographically active – and from lesional and nonlesional skin for gene expression analysis.
In terms of treatment response, the ustekinumab-treated group showed significantly higher scores for erythrocyte sedimentation rate, joint pain, and disease activity, compared with the anti–TNF-treated group. Psoriasis Area and Severity Index scores were similar in both treatment arms, but significantly more patients in the anti-TNF group met the EULAR Disease Activity Score for response (70.6% vs. 22.2%).
The gene expression analysis, which assessed the activity of 80 genes related to inflammation in 14 patient samples from synovial tissue, lesional skin, and nonlesional skin, found that patterns of expression in the synovium clustered away from those from skin.
This was particularly the case when it came to genes related to drug targets. The targets for anti-TNF showed similar levels of expression in both skin and synovial tissue. However, the targets for ustekinumab – namely interleukin (IL)–23A, IL-23R and, IL-12B – showed higher levels of expression in lesional skin than in nonlesional skin and synovial tissue.
“Interestingly, we observed that, while some patients did express IL-23 cytokines/receptor in both skin and joint, others had discordant expression, that is, active IL-23 pathway in the lesional skin but not in the synovium,” the authors wrote.
When researchers then stratified patients according to how much synovial inflammation they had, they found that patients who had higher scores also showed higher expression of genes for IL-12B and IL-23R, but not IL-23A, despite showing no other major clinical differences.
The authors also looked at the protein expression levels for IL-23p40, IL-23p19 and IL-23R, and found that while the percentage of cells positive for these proteins was significantly higher in lesional, compared with nonlesional skin, it was also higher in the synovium among patients with more inflammation.
“Except for the LIKERT patient score, we did not detect other significant correlations between IL-23 axis expression and clinical parameters at baseline, suggesting that patients with comparable disease severity may have, in fact, heterogeneous histopathological features and expression of drug targets within the diseased synovium,” they wrote.
More selective expression of IL-23 in synovium
Commenting on the findings, the authors highlighted that the expression of targets for anti-TNF was much more homogeneous across skin and synovial tissue, but the IL-23A/IL-12B/IL-23R genes generally showed higher levels of expression in lesional skin. compared with either nonlesional skin or synovium. However, even within the synovium, expression of these genes varied enormously, from levels similar to those seen in paired lesional skin to levels well below those.
“It is plausible to speculate that an overall higher presence of IL-23 in the psoriatic skin supports the concept of a generally better response in terms of skin manifestations, including almost complete clearance of psoriatic lesions,” Dr. Nerviani said in an interview. “While, on the other hand, the more selective expression of IL-23 in the synovium, namely in histologically more inflamed synovium characterized by immune cells infiltration, may explain the overall more modest success to meet stringent response criteria in the joints.“
Of particular significance was the observation that IL-12B and IL-23R transcription levels were higher in patients with higher levels of synovial tissue inflammation.
“We confirmed that IL-23 axis expression relates to the synovial histopathology not only in PsA at different stages of the disease, including early treatment-naive patients, but also in the early phase of RA, investigated as disease control,” they wrote.
Dr. Nerviani said the results could inform a more tailored “precision medicine” approach to treating patients with psoriatic arthritis.
“While randomized synovial biopsy–driven clinical trials are now a reality in rheumatoid arthritis, in psoriatic arthritis, these kinds of studies have not been performed yet but may become actual in the future,” she said. “An in-depth characterization of the synovial tissue represents the first essential step towards addressing current unmet clinical needs and, potentially, changing our practice.”
However, she stressed that the study was not powered to test the correlation between the expression level of these pathways in disease tissue and clinical response to treatment.
“Further dedicated clinical trials should be designed to look at the relationship between synovial pathology and molecular characteristics, and response to targeted treatment to address this question,” Dr. Nerviani said.
The study was supported by the Queen Mary University of London and the Fondazione Ceschina, and in part by grants from Versus Arthritis. No conflicts of interest were declared.

“Except for the LIKERT patient score, we did not detect other significant correlations between IL-23 axis expression and clinical parameters at baseline, suggesting that patients with comparable disease severity may have, in fact, heterogeneous histopathological features and expression of drug targets within the diseased synovium,” they wrote.
More selective expression of IL-23 in synovium
Commenting on the findings, the authors highlighted that the expression of targets for anti-TNF was much more homogeneous across skin and synovial tissue, but the IL-23A/IL-12B/IL-23R genes generally showed higher levels of expression in lesional skin. compared with either nonlesional skin or synovium. However, even within the synovium, expression of these genes varied enormously, from levels similar to those seen in paired lesional skin to levels well below those.
“It is plausible to speculate that an overall higher presence of IL-23 in the psoriatic skin supports the concept of a generally better response in terms of skin manifestations, including almost complete clearance of psoriatic lesions,” Dr. Nerviani said in an interview. “While, on the other hand, the more selective expression of IL-23 in the synovium, namely in histologically more inflamed synovium characterized by immune cells infiltration, may explain the overall more modest success to meet stringent response criteria in the joints.“
Of particular significance was the observation that IL-12B and IL-23R transcription levels were higher in patients with higher levels of synovial tissue inflammation.
“We confirmed that IL-23 axis expression relates to the synovial histopathology not only in PsA at different stages of the disease, including early treatment-naive patients, but also in the early phase of RA, investigated as disease control,” they wrote.
Dr. Nerviani said the results could inform a more tailored “precision medicine” approach to treating patients with psoriatic arthritis.
“While randomized synovial biopsy–driven clinical trials are now a reality in rheumatoid arthritis, in psoriatic arthritis, these kinds of studies have not been performed yet but may become actual in the future,” she said. “An in-depth characterization of the synovial tissue represents the first essential step towards addressing current unmet clinical needs and, potentially, changing our practice.”
However, she stressed that the study was not powered to test the correlation between the expression level of these pathways in disease tissue and clinical response to treatment.
“Further dedicated clinical trials should be designed to look at the relationship between synovial pathology and molecular characteristics, and response to targeted treatment to address this question,” Dr. Nerviani said.
The study was supported by the Queen Mary University of London and the Fondazione Ceschina, and in part by grants from Versus Arthritis. No conflicts of interest were declared.

Differences in gene expression between the skin and synovial tissues of individuals with psoriatic arthritis could explain why treatments targeting proinflammatory mechanisms don’t improve joint symptoms in some patients.
A paper published in Annals of the Rheumatic Diseases presents the results of an observational, open-label study involving 27 patients with active psoriatic arthritis, 18 of whom were treated with anti–tumor necrosis factor (anti-TNF) therapies and 9 with the monoclonal antibody ustekinumab (Stelara). This drug targets the axis of proinflammatory cytokine interleukin-23 and effector cytokine IL-12, which are believed to play an important role both in skin and nail psoriasis, and psoriatic arthritis.
However, while anti–IL-23 antibodies seem to work well to address skin manifestations of psoriasis, they tend to improve joint symptoms only in selected patients.
“The lack of a clear mechanism to explain such divergent responses prompted this study,” said Dr. Alessandra Nerviani, lead author of the study, from the Barts and The London School of Medicine & Dentistry.
Participants also had biopsies taken from the synovium – in particular, from joints that were clinically and ultrasonographically active – and from lesional and nonlesional skin for gene expression analysis.
In terms of treatment response, the ustekinumab-treated group showed significantly higher scores for erythrocyte sedimentation rate, joint pain, and disease activity, compared with the anti–TNF-treated group. Psoriasis Area and Severity Index scores were similar in both treatment arms, but significantly more patients in the anti-TNF group met the EULAR Disease Activity Score for response (70.6% vs. 22.2%).
The gene expression analysis, which assessed the activity of 80 genes related to inflammation in 14 patient samples from synovial tissue, lesional skin, and nonlesional skin, found that patterns of expression in the synovium clustered away from those from skin.
This was particularly the case when it came to genes related to drug targets. The targets for anti-TNF showed similar levels of expression in both skin and synovial tissue. However, the targets for ustekinumab – namely interleukin (IL)–23A, IL-23R and, IL-12B – showed higher levels of expression in lesional skin than in nonlesional skin and synovial tissue.
“Interestingly, we observed that, while some patients did express IL-23 cytokines/receptor in both skin and joint, others had discordant expression, that is, active IL-23 pathway in the lesional skin but not in the synovium,” the authors wrote.
When researchers then stratified patients according to how much synovial inflammation they had, they found that patients who had higher scores also showed higher expression of genes for IL-12B and IL-23R, but not IL-23A, despite showing no other major clinical differences.

International expert group agrees on redefining psoriasis severity
It’s high time to say farewell to the traditional categorization of psoriasis severity into mild, moderate, or severe disease, according to the International Psoriasis Council.
The mild/moderate/severe categorization is vague and defined differently by different organizations and in different countries. It often underestimates disease severity because it ignores psoriasis involvement in particularly tough-to-treat special areas, including the scalp, palms, soles, face, nails, and genitalia, Bruce E. Strober, MD, PhD, asserted at MedscapeLive’s annual Las Vegas Dermatology Seminar, held virtually this year. He chaired an IPC project in which prominent psoriasis experts in 32 countries employed a Delphi consensus approach aimed at achieving agreement on a more practical recategorization of psoriasis severity for use in both daily clinical practice and enrolling appropriate participants in clinical trials. What emerged was a simplified dichotomous categorization system.
“What we came up with is a very sensible approach to defining whether patients should get either topical or systemic therapy. In fact, there are only two groups of patients in psoriasis: those who should get topicals alone, and those who should get systemic therapy. It’s topicals or systemics,” explained Dr. Strober, a dermatologist at Yale University, New Haven, Conn., who also works in private practice in Cromwell, Conn.
Under the IPC classification, psoriasis patients are candidates for systemic therapy if they meet at least one of three criteria: body surface area of involvement greater than 10%, disease involving the previously mentioned special areas, or failure of topical therapy.
“This approach is about practically treating patients who are in need,” Dr. Strober said. “If patients meet just one of these three criteria they can move on to our current toolbox of systemic therapies, be they older systemic treatments, apremilast, phototherapy, or 1 of the 11 biologics currently approved for the treatment of psoriasis. The key point is that for patients with moderate to severe psoriasis – or should I say, systemic therapy–appropriate psoriasis – treatment should be based on individual patient characteristics. We don’t work on a stepwise approach. If a patient walks in with more than 10% body surface area involved, don’t make them fail topicals; you can go right to systemics.”
European dermatologists often use the Psoriasis Area and Severity Index (PASI) score to characterize disease severity and monitor response to therapy. In contrast, American dermatologists generally find PASI too complex and time-consuming for use in clinical practice, relying instead on the amount of body surface area involved with psoriasis. Neither of these measures incorporates disease involvement in special areas, which when present ought to automatically place a patient in the systemic therapy–appropriate category, according to Dr. Strober.
“I find this [IPC recategorization] a very practical approach. I hope you write this down and use this in your own practice,” Dr. Strober said.
The full IPC report was published in the Journal of the American Academy of Dermatology.
The IPC psoriasis severity reclassification project was unfunded. Dr. Strober reported receiving institutional research funding from and serving as a paid consultant to more than two dozen pharmaceutical companies.
