Patient selection key to lowering placebo response rates in lupus clinical trials
SEOUL, SOUTH KOREA – A major challenge for clinical trials in systemic lupus erythematosus (SLE) is how to get the placebo response rate down low enough that the effectiveness of a drug can actually be seen. Better patient selection may be the key.
Speaking at an international congress on SLE, Joan Merrill, MD, professor of medicine at the University of Oklahoma Health Sciences Center, Oklahoma City, presented on how the heterogeneity of lupus is contributing to the ongoing failure of so many potential therapies in clinical trials.
“It’s a miracle that any drug has been successful in clinical trials,” she told the conference, comparing the few drugs approved for the treatment of lupus with the much larger numbers of approved, targeted biologics that are available for rheumatoid arthritis.
The problem is that placebo response rates in clinical trials for lupus are high – well over 40% – Dr. Merrill said, and trials aren’t showing a big difference in response rates between the treatment and placebo arms. “If the placebo response is 40%, wouldn’t an effective drug help 80%?” she said. “If it also affects only 40%, does that mean it’s a failed drug?”
Dr. Merrill suggested that better patient selection could be key to achieving lower placebo response rates, which could in turn reveal if and in whom a drug might be effective. “If we could get the placebo response rate down, at least we’d be able to see a little bit better whether the drug is effective, even if it only could work in 50% of the patients,” she said.
Data from research done by the Oklahoma Medical Research Foundation suggested that patients with SLE could be loosely categorized into seven different clusters based on patterns of gene expression in areas such as interferon expression and inflammation pathways.
For example, two of those clusters represented patients with high levels of expression for both interferons and inflammation. “Maybe those are the patients who’d want to be put in a trial for interferon inhibition,” Dr. Merrill said.
This was demonstrated in a trial of type 1 interferon inhibitor anifrolumab (Saphnelo), where patients were sorted into groups according to their level of interferon expression – either high or low – based on expression of certain interferon genes. This revealed that patients in the interferon-high group had a much higher treatment effect than patients in the interferon-low group. But the difference lay in the placebo response.
“The efficacy rate was not that different between the interferon-high and the interferon-low patients,” Dr. Merrill said. “The difference was in the placebo response rate – what they had managed to find was a great marker for sicker patients.”
This phenomenon is not limited to interferon-targeted therapies. Dr. Merrill cited another literature review which looked at subset studies within clinical trials that had delivered disappointing results. This showed consistently that patients who were considered more unwell, by virtue of higher SLE Disease Activity Index (SLEDAI) scores, for example, were more likely to show an effect of treatment.
“You begin to see bigger differences between treatment and placebo because the treatment rate might go up, but mostly because the placebo rate goes down,” she said.
Another issue that could be affecting both placebo and treatment response rates is background medication. “Subset analysis of people on less background drugs was showing lower placebo response rates and better differences between treatments and placebo,” Dr. Merrill said. For example, a recent phase 2 study of anifrolumab took the strategy of actively pursuing tapering of glucocorticoids in patients where that could be done safely. That achieved a lowering of the placebo response rate to the point where a greater difference could be seen between the placebo response and the treatment response rates.
The challenge for clinical trials is therefore to identify which patients to include. “If we could figure out which patients would be the most appropriate [to enroll to fit a particular drug’s mechanism of action], then we could really get ahead of the game,” she said.
The unique problem for lupus clinic trials is the heterogeneity of lupus as a disease, Dr. Merrill said in an interview. “We’re going to have to find combinations of treatments that fit right for each patient, and they won’t necessarily be one size fits all,” she said.
Dr. Merrill said that subset analyses at the phase 2 stage could help identify the patients who responded better to the treatment and could therefore be targeted in phase 3 trials. “Once you take that hypothesis, and if you can establish and validate it in phase 3, now you’ve got yourself a biomarker,” she said.
Richard A. Furie, MD, chief of the division of rheumatology at Northwell Health in New York, agreed that the high placebo response rate was a particular nemesis for researchers involved in lupus clinical trials.
Dr. Furie said it could be that selecting sicker patients is a solution to this, as had been suggested in the subset analysis of the anifrolumab studies – which he was involved in – that identified differences in the response rates between interferon-high and interferon-low patients.
But if that was the case, the challenge would be recruiting enough of any particular subset of patients. For example, relatively few patients in the anifrolumab trial were classified as interferon low.
If the interferon expression levels are a marker for patients who are sicker, that could serve as a way to better select patients for clinical trials, he said. But it would also make it harder to achieve recruitment targets.
“I think the major problem in SLE trials is that patients have inflated activity scores, so you can gain SLEDAI scores with a little alopecia and an oral ulcer,” he said. “You can start eliminating those parameters from counting towards entry, but then as soon as you do that, you’re going to have trouble recruiting.”
Dr. Merrill reported consulting for and receiving research support from a range of pharmaceutical companies including Genentech/Roche, GlaxoSmithKline, Pfizer, Janssen, Bristol-Myers Squibb, AbbVie, and anifrolumab manufacturer AstraZeneca. Dr. Furie reported financial relationships with Genentech/Roche, GlaxoSmithKline, Kezar Life Sciences, Kyverna Therapeutics, and Takeda.

EULAR systemic sclerosis recommendations now include immunosuppressants
MILAN – Targeted synthetic and biologic therapies are recommended as disease-modifying agents for key fibrotic manifestations of systemic sclerosis for the first time in the 2023 update of European Alliance of Associations for Rheumatology recommendations for the treatment of systemic sclerosis.
Reflecting important advances over the past 8 years, mostly relating to the use of new treatments being made available to patients, the recommendations provide an update on the 2017 recommendations, which relied on evidence published through 2014. Of note, these include the use of immunosuppressive agents, for example, the monoclonal antibody rituximab (Rituxan) for skin and lung fibrosis.
“For the first time, synthetic and targeted treatments are recommended for the treatment of systemic sclerosis–interstitial lung disease, including mycophenolate mofetil [Cellcept], nintedanib [Ofev], rituximab, and tocilizumab [Actemra]. None of these were present in 2017. Mycophenolate mofetil is also recommended for the treatment of skin fibrosis, and this was not present in 2017,” Francesco Del Galdo, MD, rheumatology consultant at Leeds Teaching Hospital NHS Trust, Leeds, England, and member of the 2023 recommendations task force, said in an interview. He gave an overview of the preliminary recommendations at the annual European Congress of Rheumatology.
“Phosphodiesterase-5 [PDE-5] inhibitors and endothelin receptor antagonist [ERA] monotherapy are also recommended for up-front combination use for digital ulcers and pulmonary hypertension, and this is new for 2023 and was not present in the 2017 recommendations,” Dr. Del Galdo added.
The new recommendations also note that iloprost is categorized as having grade A evidence for use in Raynaud’s phenomenon and digital ulcers, while it has grade B evidence for pulmonary hypertension.
“We are not allowed to share the final table [of recommendations] today because the wording has only very recently been agreed” upon, Dr. Del Galdo said, but he provided a summary representation and reflected on some changes, noting that the task force is aiming to publish the 2023 recommendations by the end of the year.
Consideration and discussion of both established and new evidence highlighted a need for more evidence on the use of immunosuppressive agents in vascular manifestations of systemic sclerosis, as well as for gastrointestinal and musculoskeletal ones.
In this update to the 2017 recommendations, high-grade evidence was identified for use of immunosuppressants in skin and lung fibrosis. Grade A evidence has been accepted for the use of rituximab in skin fibrosis; for interstitial lung disease, rituximab, cyclophosphamide, and nintedanib also have grade A evidence, which is a change from the 2017 recommendations.
A total of 20 updated recommendations were agreed on, an increase from 16 in 2017. These were grouped into eight disease domains: Raynaud’s phenomenon, digital ulcers, pulmonary arterial hypertension, skin fibrosis, interstitial lung disease, musculoskeletal and gastrointestinal manifestations, and renal crisis. Interventions were then graded A-D based on the evidence reviewed.
“This approach allowed us to see clearly that there were patterns of similar recommendations in different organ manifestations, reflecting an understanding of common pathogenic pathways,” said Dr. Del Galdo.
He also noted that the development of the recommendations highlighted certain gaps in research that limit treatment options. “By grouping the recommendations in blocks – for example, skin fibrosis or vascular [manifestations] – we show that immunosuppressive treatments have only been studied in skin and lung, while vascular manifestations have very little evidence for immunosuppression. They might be effective but there’s no evidence yet [hence no recommendation in vascular manifestations].”
“Also, there’s no grade A evidence at all for musculoskeletal and gastrointestinal manifestations, and this should help to define the research agenda going forward,” Dr. Del Galdo said.
The 2023 recommendations task force comprised 28 members from 14 countries, including 18 rheumatologists, 1 EULAR methodologist, 1 health professional representative, 5 rheumatology fellows, 1 librarian, and 2 patient representatives. They used a consensual approach incorporating the views of 101 European Scleroderma Trials and Research group (EUSTAR) centers, sourced via a survey in which questions were advanced to an extensive systematic review if there was 70% or greater agreement.
Eventually, 31 questions on interventions were chosen, and the task force reviewed 12,500 abstracts (up to December 2022) related to interventions and outcomes that were either included in the 2017 recommendations or were totally new.
Dr. Del Galdo said that the three vascular manifestations of scleroderma – Raynaud’s, pulmonary arterial hypertension, and digital ulcers – were treated with the same drugs, all with a similar grade of evidence. “This suggests two things – firstly there’s a vascular disease continuum in the disease, and secondly, we’ve borrowed these drugs from vascular community, but we have not yet tested synthetic and biologic targeted treatments in these manifestations, and we should.
“Treating one manifestation may benefit the other, and this is important time wise because pulmonary hypertension usually comes around 10 years after the first phenomena so by treating digital ulcers and Raynaud’s phenomena, we may prevent pulmonary hypertension, but a study is needed,” added Dr. Del Galdo, who is also president of EUSTAR.
Finally, he pointed out that research remains particularly open for nonpharmacologic treatments for digital ulcers and severe gastrointestinal involvement. “Patients can now ask for studies into this because of the current lack of evidence.”
Moderator Ariane Herrick, PhD, professor of rheumatology at the University of Manchester (England), shared her thoughts on the guidelines. “These recommendations have been long awaited by the scleroderma community because there has been some exciting progress in recent years, and the new recommendations reflect these new developments.”
Commenting on the paucity of evidence in some areas, she added that “there do remain some huge areas of unmet need that are difficult to address, and these are musculoskeletal, gastrointestinal, and calcinosis, for which there have been no trials at all.”
Dr. Del Galdo declared disclosures relating to AstraZeneca, Janssen, Boehringer Ingelheim, Capella, Chemomab, GlaxoSmithKline, and Mitsubishi-Tanabe. Dr. Herrick disclosed serving as a consultant for Boehringer Ingelheim and Janssen.

Commenting on the paucity of evidence in some areas, she added that “there do remain some huge areas of unmet need that are difficult to address, and these are musculoskeletal, gastrointestinal, and calcinosis, for which there have been no trials at all.”

Encouraging telitacicept results reported in phase 3 for lupus, phase 2 for Sjögren’s
MILAN – Results of a phase 3 trial with the investigational drug telitacicept show that patients with systemic lupus erythematosus have a significantly greater rate of response to SLE response criteria, compared with placebo, while results from a phase 2 trial of the drug in patients with primary Sjögren’s syndrome (pSS) also show significant improvements versus placebo.
“With only a limited number of treatments available for patients with lupus, this additional option is certainly an advance and the trial shows a strong efficacy result,” said Ronald van Vollenhoven, MD, PhD, who was not an investigator for either trial but presented the results for both at the annual European Congress of Rheumatology. He is professor of clinical immunology and rheumatology at Amsterdam University Medical Center and VU University Medical Center, also in Amsterdam.
Telitacicept is a recombinant fusion protein that targets B-lymphocyte stimulator and a proliferating-inducing ligand. It is currently undergoing testing in another phase 3 trial (REMESLE-1) at sites in the United States, Europe, and Asia. The current SLE results relate to the phase 3 study conducted in China, Dr. van Vollenhoven clarified.
SLE trial
The double-blind, placebo-controlled trial included 335 patients with SLE who had an average age of 35 years, a body mass index of 22-23 kg/m2, and a mean SELENA-SLEDAI (Safety of Estrogens in Systemic Lupus Erythematosus National Assessment–Systemic Lupus Erythematosus Disease Activity Index) score of at least 11.5, indicating high disease activity. Most patients were on glucocorticoids and immunosuppressants.
Patients were randomized 1:1 to weekly subcutaneous injections of telitacicept (160 mg; n = 167) or placebo (n = 168) in combination with standard therapy for 52 weeks. The primary endpoint was the SLE Responder Index-4 (SRI4) response rate at week 52, while key secondary endpoints included SELENA-SLEDAI, physician global assessment, and levels of immunologic biomarkers including C3, C4, IgM, IgG, IgA, and CD19+ B cells. Safety was also assessed.
At week 52, Dr. van Vollenhoven reported that significantly more patients taking telitacicept achieved a SRI4 response, compared with placebo, at 67.1% versus 32.7%, respectively (P < .001). “The difference was seen at 4-8 weeks and stabilized at around 20 weeks,” he said.
Time to first SLE flare was also reduced in patients on the trial drug at a median of 198 days (95% confidence interval, 169-254 days), compared with placebo at 115 days (95% CI, 92-140 days).
“The secondary outcomes also supported efficacy in these patients,” Dr. van Vollenhoven added, noting that there was a rapid and sustained increase of C3 and C4, the latter being significantly greater than placebo, and reduction of IgM, IgG, IgA, and CD19+ B cells observed following telitacicept treatment.
A significantly higher proportion of patients in the telitacicept group showed improvement in SELENA-SLEDAI at week 52, defined as a 4-point or greater reduction, compared with placebo (70.1% vs. 40.5%).
Telitacicept did not increase the risk of infections. Treatment-emergent adverse events occurred in 84.5% with telitacicept versus 91.6% with placebo, with infections (mostly upper respiratory) seen in 65.3% and 60.1%, respectively.
Sjögren’s trial
The second trial was a phase 2, randomized, placebo-controlled, 24-week study in 42 patients with pSS. Patients (18-65 years) received telitacicept at 160 mg or 240 mg subcutaneously once a week, or placebo, for a total of 24 doses. Patients had a EULAR Sjögren’s Syndrome Disease Activity Index (ESSDAI) score of 5 points or more, and were anti-SSA antibody positive.
“Compared with placebo, telitacicept treatment resulted in significant improvement in ESSDAI and MFI-20 [20-item Multidimensional Fatigue Inventory],” Dr. van Vollenhoven reported, adding that, “there was a trend for improvement in salivary gland function and lacrimal gland function relative to placebo, as well as a favorable safety profile.”
ESSDAI change from baseline was 0.5, –3.8, and –2.3 in placebo, 160-mg, and 240-mg telitacicept doses, respectively. MFI-20 change from baseline was 7.0, –4.0, and –5.1, respectively. Dr. Van Vollenhoven said the difference between the doses was not statistically significant.
“If these results are confirmed, it could be the first time a biologic is proven efficacious in this disease,” Dr. Van Vollenhoven said in an interview. “It’s encouraging to know that a new treatment is showing promise in this phase 2 trial. A phase 3 trial is warranted.”
Studies yield promising but confusing results
In an interview, Roy Fleischmann, MD, who was not involved with either study, wondered whether the results of the SLE study could be race specific given the magnitude of response to the drug and that the trial was conducted only in China, and whether the positive results of the small Sjögren’s study will pan out in a larger trial.
“The SLE study was very interesting, but the problem is that it’s a Chinese drug in Chinese patients with Chinese doctors, so they are very dramatic results,” he said, questioning whether “these results are race specific,” and that “we will find out when they do the multinational study, but we haven’t seen this type of separation before [in response]. It’s interesting.
“The Sjögren’s was a positive study, but it was confusing because the low dose seemed to be better than the higher dose, and there were very few patients,” said Dr. Fleischmann, clinical professor of medicine at the University of Texas Southwestern Medical Center and codirector of the Metroplex Clinical Research Center, both in Dallas. The left and right eyes gave different results, which was strange, and the salivary gland test was the same [mixed results], so what can we conclude? All in all, it was a small study with a suggestion of efficacy, but we have to do the phase 3 and see what it shows.”
Both trials were sponsored by RemeGen. Dr. van Vollenhoven reported serving as a paid adviser to AbbVie, AstraZeneca, Biogen, Bristol-Myers Squibb, Galapagos, GlaxoSmithKline, Janssen, Pfizer, RemeGen, and UCB. He has received research funding from Bristol-Myers Squibb and UCB and educational support from AstraZeneca, Galapagos, Merck Sharp & Dohme, Novartis, Pfizer, Roche, Sanofi, and UCB. Dr. Fleischmann said he had has no relevant financial relationships.

Scientists discover variants, therapy for disabling pansclerotic morphea
A team of especially in patients who have not responded to other interventions.
DPM was first reported in 1923, and while a genetic cause has been suspected, it had not been identified until now. The disease is the most severe form of deep morphea, which affects individuals with juvenile localized scleroderma. Patients, generally children under age 14, experience rapid sclerosis of all layers of the skin, fascia, muscle, and bone. DPM is also deadly: Most patients do not live more than 10 years after diagnosis, as they contract squamous cell carcinoma, restrictive pulmonary disease, sepsis, and gangrene.
In the study, published in the New England Journal of Medicine, the researchers discovered that people with DPM have an overactive version of the protein STAT4, which regulates inflammation and wound healing. The scientists studied four patients from three unrelated families with an autosomal dominant pattern of inheritance of DPM.
“Researchers previously thought that this disorder was caused by the immune system attacking the skin,” Sarah Blackstone, a predoctoral fellow in the inflammatory disease section at the National Human Genome Research Institute and co–first author of the study, said in a statement from the National Institutes of Health describing the results. “However, we found that this is an oversimplification, and that both skin and the immune system play an active role in disabling pansclerotic morphea,” added Ms. Blackstone, also a medical student at the University of South Dakota, Sioux Falls.
The overactive STAT4 protein creates a positive feedback loop of inflammation and impaired wound-healing. By targeting JAK, the researchers were able to stop the feedback and patients’ wounds dramatically improved. After 18 months of treatment with oral ruxolitinib, one patient had discontinued all other medications, and had complete resolution of a chest rash, substantial clearing on the arms and legs, and global clinical improvement.
The authors said that oral systemic JAK inhibitor therapy is preferred over topical therapy. Their research also suggested that anti–interleukin-6 monoclonal antibodies – such as tocilizumab, approved for indications that include rheumatoid arthritis and systemic sclerosis–associated interstitial lung disease, “may be an alternative therapy or may be useful in combination with JAK inhibitors in patients with DPM,” the authors wrote.
Most current DPM therapies – including methotrexate, mycophenolate mofetil, and ultraviolet A light therapy – have been ineffective, and some have severe side effects.
“The findings of this study open doors for JAK inhibitors to be a potential treatment for other inflammatory skin disorders or disorders related to tissue scarring, whether it is scarring of the lungs, liver or bone marrow,” Dan Kastner, MD, PhD, an NIH distinguished investigator, head of the NHGRI’s inflammatory disease section, and a senior author of the paper, said in the NIH statement.
“We hope to continue studying other molecules in this pathway and how they are altered in patients with disabling pansclerotic morphea and related conditions to find clues to understanding a broader array of more common diseases,” Lori Broderick, MD, PhD, a senior author of the paper and an associate professor at University of California, San Diego, said in the statement.
The study was led by researchers at NHGRI in collaboration with researchers from UCSD and the University of Pittsburgh. Researchers from the National Institute of Arthritis and Musculoskeletal and Skin Diseases and the National Institute of Allergy and Infectious Diseases also participated.
The study was supported by grants from the American Academy of Allergy, Asthma, and Immunology Foundation; the Ludwig Institute for Cancer Research; the University of California, San Diego, department of pediatrics; and the Novo Nordisk Foundation. Additional support and grants were given by the Deutsche Forschungsgemeinschaft, various institutes at the NIH, the California Institute for Regenerative Medicine, the Hydrocephalus Association, the Scleroderma Research Foundation, the Biowulf High-Performance Computing Cluster of the Center for Information Technology, the Undiagnosed Diseases Program of the Common Fund of the Office of the Director of the NIH, and the NIH Clinical Center.

Investigational lupus drug cenerimod moves to phase 3 studies after equivocal phase 2 results
SEOUL, SOUTH KOREA – A once-daily, oral dose of the investigational drug cenerimod, developed for the treatment of systemic lupus erythematosus, has shown a greater response rate among individuals with more severe disease, according to data presented at an international congress on SLE.
Cenerimod is a potent, highly-selective sphingosine 1–phosphate receptor 1 (S1P1) modulator with attenuated calcium signaling, which targets an important signaling molecule in immunity and cell migration, said rheumatologist Sandra Navarra, MD, of the University of Santo Tomas Hospital and St. Luke’s Medical Center in Manila, Philippines.
“It reduces the migration of T cells and B cells from the lymph nodes to the circulation into the tissues,” Dr. Navarra told the conference. S1P1 receptor modulators are already approved for treatment of multiple sclerosis, but cenerimod is the first to be explored for the treatment of lupus.
Dr. Navarra presented data from the international CARE study, a randomized, placebo-controlled, phase 2 study involving 427 patients with moderate to severe SLE.
Patients had to have been diagnosed at least 6 months before screening, be on stable lupus medications, and have abnormal antinuclear or anti–double stranded DNA antibodies. They were randomized to either 0.5 mg, 1 mg, 2 mg, or 4 mg of cenerimod daily or placebo for 12 months. At 6 months, the patients who had initially been randomized to 4 mg daily were rerandomized either to 2 mg daily or placebo.
While the study found that 4 mg of cenerimod was associated with a reduction in disease activity from baseline to month 6 on the modified Systemic Lupus Erythematosus Disease Activity Index–2000 score (excluding leukopenia), compared with placebo (P = .029). However, the final result was not statistically significant after adjustment for the multiplicity of tests for the four doses against placebo.
But the researchers saw a greater response among individuals with higher levels of interferon type 1 gene expression at baseline, as well as those with higher anti-dsDNA and lower C4 levels, which “makes sense,” Dr. Navarra said in an interview, because those were the sicker patients with “more inflammatory, more active disease.”
The study did exclude patients with active lupus nephritis, severe active central nervous system lupus, or severe cardiovascular disorders.
Dr. Navarra said the findings are now factored into patient selection for two phase 3 trials, called OPUS-1 and OPUS-2, which are now underway. The OPUS trials have revised eligibility criteria, as well as a screening period of up to 60 days to ensure that only patients with true moderate to severe SLE are enrolled.
The drug was well tolerated, with the rate of adverse events similar across all study groups. The adverse events of particular interest – hypertension, infections and infestations, and eye disorders – were all mild and transient. There were a greater number of reports of hypertension among those taking 1-mg and 4-mg doses of cenerimod, but Dr. Navarra said monthly measurements of systolic or diastolic blood pressure didn’t show any change.
The study was funded by cenerimod manufacturer Idorsia Pharmaceuticals. Dr. Navarra has financial relationships with Biogen, Astellas, Janssen, Novartis, Pfizer, Boehringer-Ingelheim, and GlaxoSmithKline.
SEOUL, SOUTH KOREA – A once-daily, oral dose of the investigational drug cenerimod, developed for the treatment of systemic lupus erythematosus, has shown a greater response rate among individuals with more severe disease, according to data presented at an international congress on SLE.
Cenerimod is a potent, highly-selective sphingosine 1–phosphate receptor 1 (S1P1) modulator with attenuated calcium signaling, which targets an important signaling molecule in immunity and cell migration, said rheumatologist Sandra Navarra, MD, of the University of Santo Tomas Hospital and St. Luke’s Medical Center in Manila, Philippines.
“It reduces the migration of T cells and B cells from the lymph nodes to the circulation into the tissues,” Dr. Navarra told the conference. S1P1 receptor modulators are already approved for treatment of multiple sclerosis, but cenerimod is the first to be explored for the treatment of lupus.
Dr. Navarra presented data from the international CARE study, a randomized, placebo-controlled, phase 2 study involving 427 patients with moderate to severe SLE.
Patients had to have been diagnosed at least 6 months before screening, be on stable lupus medications, and have abnormal antinuclear or anti–double stranded DNA antibodies. They were randomized to either 0.5 mg, 1 mg, 2 mg, or 4 mg of cenerimod daily or placebo for 12 months. At 6 months, the patients who had initially been randomized to 4 mg daily were rerandomized either to 2 mg daily or placebo.
While the study found that 4 mg of cenerimod was associated with a reduction in disease activity from baseline to month 6 on the modified Systemic Lupus Erythematosus Disease Activity Index–2000 score (excluding leukopenia), compared with placebo (P = .029). However, the final result was not statistically significant after adjustment for the multiplicity of tests for the four doses against placebo.

Severe hydroxychloroquine nonadherence linked to worse SLE outcomes
SEOUL, SOUTH KOREA – Regular testing of hydroxychloroquine levels in patients with systemic lupus erythematosus – especially those who are experiencing a disease flare – could help to identify patients who are not taking their treatment and are at risk of worse outcomes.
Data presented at an international congress on systemic lupus erythematosus showed that 7.3% of patients with SLE are severely nonadherent to their medication and have a higher risk of flare, early damage, and mortality.
Rheumatologist Nathalie Costedoat-Chalumeau, MD, PhD, professor of internal medicine at Cochin Hospital, Paris, presented data from 660 patients enrolled in the international longitudinal SLICC Inception Cohort, who had all been on hydroxychloroquine therapy for at least 3 months at baseline.
Patients’ serum hydroxychloroquine levels were measured at baseline and follow-up, and severe nonadherence was defined as below 106 ng/mL for those on 400 mg/day or 53 ng/mL for those on 200 mg/day.
Dr. Costedoat-Chalumeau said that those thresholds were chosen based on earlier work that analyzed the blood concentration of hydroxychloroquine in a group of patients and identified a group with very low concentrations corresponding to severe nonadherence.
“Since then, it has been reproduced by others with the same threshold,” she said. “When you have very low levels of hydroxychloroquine in their blood, you know that your patients don’t take their treatment.”
In the present study, the 7.3% of patients who met the criteria for severe nonadherence had a significant 3.3-fold higher risk of disease flare within a year of enrollment than did those who were adherent. They also had significantly higher mortality at 5 years after enrollment.
While the study didn’t show a significant difference in the level of damage at 5 years – defined as a worsening of their SLICC damage index – Dr. Costedoat-Chalumeau said they saw significantly greater damage occurring at 1, 2, and 3 years after enrollment among those who were severely nonadherent.
The challenge with recognizing these nonadherent patients is that they have no obvious differences at baseline from those who are adherent, Dr. Costedoat-Chalumeau said. The rates of nonadherence were similar regardless of what dose the patient was on, their ethnicity, gender, education level, or other demographic variables.
“I believe strongly that there is a benefit of testing hydroxychloroquine levels in the blood or serum to detect severe nonadherence,” she said.
At Dr. Costedoat-Chalumeau’s clinic, patients’ hydroxychloroquine levels are tested at every clinic visit, she said in an interview, and especially if they are experiencing a disease flare. “We want to know if the flare is because the patient is not taking the treatment or if it’s because the treatment is not effective, which is very different in terms of management,” she said. She recommended waiting at least 1 month after patients start treatment before measuring their hydroxychloroquine levels.
As to why some patients choose to stop taking their medication, Dr. Costedoat-Chalumeau said sometimes it was because patients were worried about side effects, but others were also unclear about why they needed to keep taking hydroxychloroquine.
“They think steroids are effective because when they take it they are better, but they don’t see the effect of hydroxychloroquine,” she said. “You have to explain that it doesn’t work the same.”
Commenting on the findings, session chair Joan Merrill, MD, professor of medicine at the University of Oklahoma Health Sciences Center, Oklahoma City, said the data show that severe nonadherence does have prognostic significance. “Many patients with SLE have low-grade disease or inflammation in the blood vessels that may not be clinically apparent and which hydroxychloroquine can help, so it might be wise to routinely get blood levels,” she said.
Dr. Costedoat-Chalumeau reported no relevant financial relationships apart from unrestricted institutional research grants from UCB and Roche.

Lupus landmark study aims for personalized medicine goals
A new prospective, observational study from the Lupus Research Alliance (LRA) aims to enroll 3,500 patients in an effort to accelerate the development of personalized treatments for individuals living with systemic lupus erythematosus (SLE).
The LRA on May 23 announced the launch of the Lupus Landmark Study (LLS). The study will be conducted in partnership with Lupus Therapeutics, the clinical research affiliate of the LRA.
The study will be a key feature of the Lupus Nexus, a unique combination of lupus patient registry, biorepository, and portal for data sharing and analysis.
“The aim of the Lupus Nexus is to transform lupus research and drug development through unprecedented information exchange capabilities,” according to the LRA press release.
“SLE is a debilitating autoimmune disease that disproportionately impacts women and people from minority groups, but the cause of lupus is unknown, and no single laboratory test can definitively identify lupus,” lead investigator S. Sam Lim, MD, of Emory University, Atlanta, told this news organization.
“Nevertheless, early detection and treatment can often lessen the progression and severity of the disease. Although there are numerous contributing factors to the lag in research discoveries and new treatments for patients with lupus, limited access to standardized, high-quality biological samples and natural history data provides a significant roadblock to advancing lupus research,” Dr. Lim said.
“Existing registry and biorepository resources in the lupus field are largely siloed, mostly limited to relatively small or discrete patient populations, and frequently not designed for broad sharing across all stakeholders of the research community,” Dr. Lim said. The LRA and its affiliate Lupus Therapeutics are committed to developing Lupus Nexus, a first-of-its-kind registry and biorepository, to serve as a collaborative research platform for lupus and a leading source of prospective, longitudinal patient data and biological samples for the research community, Dr. Lim added.
“The Lupus Landmark Study will form the foundation of this registry and biorepository and will provide a critical resource to enable the understanding of lupus heterogeneity at the molecular level,” Dr. Lim said. The molecular data can be linked to clinical phenotypes, he explained, “while providing an opportunity to better understand the holistic experience of patients with lupus, thus helping patients address the daily life challenges they face.”
The Lupus Accelerating Breakthroughs Consortium (Lupus ABC) was announced earlier this spring by the LRA. It represents a collaboration between the U.S. Food and Drug Administration and the lupus community to improve and accelerate the development of safer and more effective treatments for people with lupus, Dr. Lim said. “Data and other results from the LLS will inform this collaboration,” he said.
“The LLS will provide greater insight into the pathogenesis and evolution of the condition, providing much needed information and guidance to clinicians so that the disease can be detected and treated earlier and with better precision,” Dr. Lim said. “The partnership with patients will ensure that advances will not only be meaningful to clinicians but their patients and caregivers as well,” he added.
Individuals living with lupus were essential to the development of the Lupus Nexus, and patients will continue to be engaged through participation in the LLS, which will not only generate data to promote patient-centered treatments but will also give participants more insight into their health data, according to the LRA press release.
The clinical coordinating center and biorepository elements of the Lupus Nexus will be managed by Embleema and Azenta Life Sciences, respectively, according the LRA.
Biomarker analysis will be conducted by DxTerity Diagnostics via the company’s proprietary DxCollection MicroCollection Device and Modular Immune Profile platform.
The LLS is scheduled to begin enrolling patients through select academic medical centers in the Lupus Therapeutics Lupus Clinical Investigators Network later in 2023, with an expanded roll-out in 2024, according to the press release.

Cutaneous vasculitis curtails quality of life
, and its measurement with an organ-specific instrument may catch important disease outcomes better than a generic health-related quality of life index, according to survey responses from participants in the Vasculitis Patient-Powered Research Network (VPPRN).
Although cutaneous vasculitis often causes itching, pain, and ulceration, the impact of the disease on specific health-related quality of life (HRQOL) outcomes has not been systematically assessed, wrote Sarah Mann, MD, of the University of Pittsburgh, and colleagues.
In a study published in JAMA Dermatology, the researchers used the VPPRN to conduct an online survey of adults aged 18 years and older with cutaneous manifestations of vasculitis. The survey was conducted between January 2020 and August 2021.
The primary outcomes of HRQOL were determined using two validated measures. One measured skin-related HRQOL (the Effects of Skin Disease on Quality-of-Life Survey [Skindex-29]), and the other measured general health and well-being (36-Item Short Form Health Survey [SF-36]).
The final analysis included 190 survey responses. The mean age of the respondents was 50.5 years, 84.1% were female, and approximately two-thirds reported a duration of vasculitis of at least 5 years. Respondents’ vasculitides included cutaneous small-vessel vasculitis (14%), IgA vasculitis (6.5%), urticarial vasculitis (8.4%), granulomatosis with polyangiitis (17.6%), microscopic polyangiitis (10.3%), eosinophilic vasculitis (15%), polyarteritis nodosa (3.7%), and other vasculitis types (24.2%).
On the Skindex-29 domains, severely or very severely diminished HRQOL was reported by 77.6% of respondents for emotions, 78.5% for symptoms, 60.7% for functioning, and 75.7% for overall HRQOL.
On the SF-36, the HRQOL was below average on six of eight domains, and approximately half of the patients had summative physical component scores (56%) and mental component scores (52%) below 50.
The HRQOL outcomes of cutaneous vasculitis were worse on the Skindex-29 than the SF-36, the researchers noted. “This discordance may reflect the value of disease or organ-specific measures, which may be able to capture important outcomes of disease even when generic measures do not,” they said.
The study findings were limited by several factors, including the potential lack of generalizability to broader populations of vasculitis patients, the researchers noted. Other limitations included the underrepresentation of male patients and the lack of a disease-specific patient-reported outcome measure, they said.
In addition, “Because half of patients reported having disease which was in remission or mildly active, the study findings may underestimate the true role of active cutaneous vasculitis on HRQOL,” the researchers said.
More studies are needed to assess how HRQOL measures respond to disease treatment and control, the researchers wrote in their discussion. However, the results suggest that cutaneous vasculitis has a significant effect on patients’ perception of their health, as well as on their well-being and symptoms, they said.
The study was supported by the Patient-Centered Outcomes Research Institute and GlaxoSmithKline. Dr. Mann had no financial conflicts to disclose. Several coauthors disclosed relationships with multiple companies, including GlaxoSmithKline.

Respondents’ vasculitides included cutaneous small-vessel vasculitis (14%), IgA vasculitis (6.5%), urticarial vasculitis (8.4%), granulomatosis with polyangiitis (17.6%), microscopic polyangiitis (10.3%), eosinophilic vasculitis (15%), polyarteritis nodosa (3.7%), and other vasculitis types (24.2%).
On the Skindex-29 domains, severely or very severely diminished HRQOL was reported by 77.6% of respondents for emotions, 78.5% for symptoms, 60.7% for functioning, and 75.7% for overall HRQOL.
On the SF-36, the HRQOL was below average on six of eight domains, and approximately half of the patients had summative physical component scores (56%) and mental component scores (52%) below 50.
The HRQOL outcomes of cutaneous vasculitis were worse on the Skindex-29 than the SF-36, the researchers noted. “This discordance may reflect the value of disease or organ-specific measures, which may be able to capture important outcomes of disease even when generic measures do not,” they said.
The study findings were limited by several factors, including the potential lack of generalizability to broader populations of vasculitis patients, the researchers noted. Other limitations included the underrepresentation of male patients and the lack of a disease-specific patient-reported outcome measure, they said.
In addition, “Because half of patients reported having disease which was in remission or mildly active, the study findings may underestimate the true role of active cutaneous vasculitis on HRQOL,” the researchers said.
More studies are needed to assess how HRQOL measures respond to disease treatment and control, the researchers wrote in their discussion. However, the results suggest that cutaneous vasculitis has a significant effect on patients’ perception of their health, as well as on their well-being and symptoms, they said.
The study was supported by the Patient-Centered Outcomes Research Institute and GlaxoSmithKline. Dr. Mann had no financial conflicts to disclose. Several coauthors disclosed relationships with multiple companies, including GlaxoSmithKline.
, and its measurement with an organ-specific instrument may catch important disease outcomes better than a generic health-related quality of life index, according to survey responses from participants in the Vasculitis Patient-Powered Research Network (VPPRN).
Although cutaneous vasculitis often causes itching, pain, and ulceration, the impact of the disease on specific health-related quality of life (HRQOL) outcomes has not been systematically assessed, wrote Sarah Mann, MD, of the University of Pittsburgh, and colleagues.
In a study published in JAMA Dermatology, the researchers used the VPPRN to conduct an online survey of adults aged 18 years and older with cutaneous manifestations of vasculitis. The survey was conducted between January 2020 and August 2021.
The primary outcomes of HRQOL were determined using two validated measures. One measured skin-related HRQOL (the Effects of Skin Disease on Quality-of-Life Survey [Skindex-29]), and the other measured general health and well-being (36-Item Short Form Health Survey [SF-36]).
The final analysis included 190 survey responses. The mean age of the respondents was 50.5 years, 84.1% were female, and approximately two-thirds reported a duration of vasculitis of at least 5 years.

IVIG shows no impact on VTE risk in dermatomyositis patients
Use of intravenous immunoglobulin (IVIG) had no apparent effect on the risk of venous thromboembolism (VTE) in adults with dermatomyositis (DM), based on data from more than 400 individuals.
DM has been associated with an increased risk of VTE in previous studies, wrote Elizabeth T. Rotrosen, of Boston University and Brigham and Women’s Hospital, Boston, and colleagues. Although IVIG is often effective for DM patients with recalcitrant disease, it carries a boxed warning for increased thrombosis risk; however, the association between IVIG use and VTE risk in DM has not been well examined, the researchers said.
In a study published in JAMA Dermatology, the researchers identified 458 adults with DM based on the European Alliance of Associations for Reumatology/American College of Rheumatology criteria. The mean age of the participants was 51.8 years, 76% were female, and 82% were White. Of these, 178 were treated with IVIG and 280 were not. The mean duration of IVIG treatment was 32.9 months. The researchers used the chi square test to test for independence between binary variables, the Pearson chi square test to test for independence between categorical variables, and the unpaired t test to compare continuous variables in their statistical analysis.
A total of 23 patients experienced DM-associated VTEs; 6 in the IVIG group and 17 in the non-IVIG group (3.4% vs. 5.7%, P = .20), a nonsignificant difference. The patients in the IVIG group who experienced a DM-associated VTE all underwent IVIG treatment within 4 weeks before the event.
The most common risk factors for VTE in both the IVIG and non-IVIG groups were malignant neoplasm (66.7% and 58.8%, respectively), followed by immobilization (16.7% and 35.3%, respectively) and tobacco use (16.7% and 23.5%, respectively).
“Notably, 5 of the IVIG-treated patients with DM who experienced a VTE also had at least 1 additional underlying risk factor for VTE, including 4 with malignant neoplasm,” the researchers wrote.
A total of 76 patients had cancer-associated DM, including 12 treated with IVIG and 64 not treated with IVIG. Of these, 14 experienced a VTE (4 IVIG patients and 10 non-IVIG patients).
The study findings were limited by several factors, including the retrospective design and small number of VTEs. Prospective studies are needed for better assessment of the VTE risk in patients with DM treated with IVIG, the researchers noted. However, the study is the largest known to explore the association between IVIG use and VTE risk in patients with DM, they said, and the results suggest that clinicians may continue IVIG use in these patients with considerations of risks and benefits on an individual basis.
The study received no outside funding. Ms. Rotrosen had no financial conflicts to disclose. Two coauthors reported financial relationships with Pfizer unrelated to this study.

FDA fast tracks potential CAR T-cell therapy for lupus
The U.S. Food and Drug Administration has granted Fast Track designation for Cabaletta Bio’s cell therapy CABA-201 for the treatment of systemic lupus erythematosus (SLE) and lupus nephritis (LN), the company announced May 1.
The FDA cleared Cabaletta to begin a phase 1/2 clinical trial of CABA-201, the statement says, which will be the first trial accessing Cabaletta’s Chimeric Antigen Receptor T cells for Autoimmunity (CARTA) approach. CABA-201, a 4-1BB–containing fully human CD19-CAR T-cell investigational therapy, is designed to target and deplete CD19-positive B cells, “enabling an ‘immune system reset’ with durable remission in patients with SLE,” according to the press release. This news organization previously reported on a small study in Germany, published in Nature Medicine, that also used anti-CD19 CAR T cells to treat five patients with SLE.
This upcoming open-label study will enroll two cohorts containing six patients each. One cohort will be patients with SLE and active LN, and the other will be patients with SLE without renal involvement. The therapy is designed as a one-time infusion and will be administered at a dose of 1.0 x 106 cells/kg.
“We believe the FDA’s decision to grant Fast Track Designation for CABA-201 underscores the unmet need for a treatment that has the potential to provide deep and durable responses for people living with lupus and potentially other autoimmune diseases where B cells contribute to disease,” David J. Chang, MD, chief medical officer of Cabaletta, said in the press release.
FDA Fast Track is a process designed to expedite the development and review of drugs and other therapeutics that treat serious conditions and address unmet medical needs. Companies that receive Fast Track designation for a drug have the opportunity for more frequent meetings and written communication with the FDA about the drug’s development plan and design of clinical trials. The fast-tracked drug can also be eligible for accelerated approval and priority review if relevant criteria are met.
