The Food and Drug Administration has approved rituximab-pvvr (Ruxience) for adults with non-Hodgkin lymphoma, chronic lymphocytic leukemia (CLL), and granulomatosis with polyangiitis and microscopic polyangiitis. It is the first biosimilar approved to treat these two rare autoimmune conditions.

Specifically, the biosimilar product is approved as single-agent therapy for relapsed or refractory, low grade or follicular, CD20-positive B-cell non-Hodgkin lymphoma; in combination with chemotherapy for other types of previously untreated CD20-positive B-cell non-Hodgkin lymphoma; and as a single agent for nonprogressing, low-grade, CD20-positive B-cell non-Hodgkin lymphoma after first-line chemotherapy treatment. It is also approved for both previously untreated and previously treated CD20-positive CLL in combination with chemotherapy. And it is approved for granulomatosis with polyangiitis and microscopic polyangiitis in combination with glucocorticoids.

The approval is based on demonstration that rituximab-pvvr had no clinically meaningful differences in safety or efficacy when compared with the reference drug, rituximab (Rituxan), according to a release from the biosimilar’s developer. As with rituximab, rituximab-pvvr’s label comes with an FDA boxed warning. In the biosimilar’s case, it warns against fatal infusion-related reactions, severe mucocutaneous reactions, hepatitis B virus reactivation, and progressive multifocal leukoencephalopathy. Other adverse reactions include fever, headache, neutropenia, and lymphopenia.

The Food and Drug Administration has expanded the indication for apremilast (Otezla) to include the treatment of oral ulcers associated with Behçet’s disease in adults, according to an announcement from the manufacturer, Celgene.

FDA approval was based on results of the randomized, placebo-controlled, double-blind, phase 3 RELIEF trial, in which 207 patients with Behçet’s disease with active ulcers underwent treatment for 12 weeks with 30 mg apremilast or placebo. When measured on a visual analog scale, the reduction in pain from oral ulcers after 12 weeks in patients receiving apremilast was 42.7 points, compared with 18.7 points in the placebo group. Just over 50% of apremilast patients achieved complete response by week 12, compared with 22.3% in the placebo group.

The most common adverse events associated with apremilast during RELIEF were diarrhea, nausea, headache, and upper respiratory infection. This was consistent with apremilast’s known safety profile.


Apremilast is also indicated for treatment of patients with moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapy, and for patients with active psoriatic arthritis.

“Oral ulcers are a recurring and debilitating manifestation that affects nearly everyone living with Behçet’s disease and have an important negative impact on the quality of life for these patients. In the clinical trial, Otezla demonstrated improvements in measures of oral ulcers at week 12. Otezla has the potential to be a needed treatment option for U.S. patients and their physicians, who previously had limited options available,” Yusuf Yazici, MD, clinical associate professor in the department of medicine at New York University, said in the announcement.

MADRID – Low-dose aspirin is recommended for the primary prevention of antiphospholipid syndrome (APS) in patients at high risk for developing the condition, according to new recommendations developed by the European League Against Rheumatism (EULAR).

Sara Freeman/MDEdge News

Indeed, the NSAID should be given at a dose of between 75 mg and 100 mg per day, in patients with a “high risk” antiphospholipid (aPL) antibody profile, including asymptomatic aPL antibody carriers, patients with systemic lupus erythematosus (SLE) without APS, and in women who are not pregnant but who have a history of obstetric APS.

The recommendations, which are the first evidence-based guidelines for adult APS to be produced by EULAR, also cover the secondary prevention of APS and how to manage individuals with recurrent episodes.

The recommendations aim to help guide practice and ultimately to improve the quality of care for patients and their outcomes following treatment, Maria G. Tektonidou, MD, PhD, said at the European Congress of Rheumatology.

The guidance is necessary as “clinical practice in APS remains highly variable,” said Dr. Tektonidou of the National and Kapodistrian University of Athens. This is perhaps because APS is a “rare disease and also because it’s a newly recognized disease – it’s only 35 years old – and knowledge about the clinical spectrum, classification, and management is continuously advancing.”

Dr. Tektonidou, who was the convener of the EULAR Task Force that wrote the recommendations, noted that they were now published in Annals of the Rheumatic Diseases and considered three main groups of patients: those with thrombotic APS, those with obstetric APS, and those with catastrophic APS (CAPS). There are three overarching principles, 12 recommendations, and 29 graded statements, she said.

The three overarching principles concerned risk stratification, general measures for managing patients who test positive for aPL antibodies, and patient education and counseling on various topics, such as treatment adherence, therapeutic drug monitoring, contraceptive use, and lifestyle interventions.

Dr. Tektonidou highlighted how risk stratification was important and that a high-risk aPL profile was defined as the presence of lupus anticoagulant (LA) on at least two occasions, measured 12 weeks apart according to International Society on Thrombosis and Haemostasis guidelines, or the presence of two or even three aPL antibodies, or persistently high aPL antibody titers. By contrast, a low-risk aPL profile was defined as the isolated presence of anticardiolipin (aCL) or anti–beta-2 glycoprotein I antibodies at low-medium titers, particularly if transiently positive.

“Risk stratification should include the determination of the high-risk aPL profile; a prior history of thrombotic or obstetric [APS]; the coexistence of other systemic autoimmune diseases, and the presence of traditional cardiovascular risk factors,” Dr. Tektonidou said.

Four of the recommendations focus on the secondary prevention of APS, giving guidance on anticoagulant treatment with definite APS, first provoked or unprovoked venous thrombosis, and how to manage recurrent venous thrombosis. There also is a recommendation for the management of patients with definite APS and a first arterial thrombosis, outlining the type and intensity of anticoagulant therapy that should be given. Another four of the recommendations focus on the management of obstetric APS, with a focus on how to manage the various types of complications seen in pregnant women. Then the final recommendation concerns CAPS, it’s prevention and first-line treatment, and how to manage refractory patients.

Sara Freeman/MDEdge News

With regards to CAPS, Ricard Cervera, MD, PhD, of the Hospital Clinic of Barcelona, this is “terrible” but “thankfully rare” form of APS that was first described in the early 1990s.

Although fewer than 1% of the APS adult population have CAPS (Arthritis Rheum. 2002;46[4]:1019-27), it’s a condition in which several thrombotic events occur simultaneously, affecting multiple systems or organs and which can be life threatening if not treated quickly.
 

New treatment guidelines for catastrophic APS

During a separate clinical science session at the conference, Dr. Cervera discussed the development of treatment guidelines for CAPS, noting that this had been one of the focus points of the McMaster RARE-Bestpractices project group in 2016. The group selected CAPS for a pilot exercise in guideline development for a rare disease and published their recommendations in 2018 (J Thromb Haemost. 2018;16:1656-64). Ten recommendations were developed, most of which were conditional, Dr. Cervera said, due to the lack of, or very low certainty, of the evidence.

The new EULAR 2019 adult APS recommendations now include CAPS and recommendation number 12 is split into two parts. The first, part A, states that prompt treatment of infections is needed in all patients positive for aPL antibodies and that anticoagulation should have minimal interruption or be used at level to help prevent the development of CAPS.

The second, part B, states that the first-line treatment of CAPS should be a triple combination therapy of glucocorticoids, heparin, and plasma exchange, or intravenous immunoglobulins, rather than single-agent treatment. Plus, it says that any triggering factor should be treated accordingly.

“Finally,” Dr. Cervera said, “in patients with refractory CAPS, B-cell depletion with rituximab or complement inhibitors, for example eculizumab, may be considered.”

The adult APS recommendations project was funded by EULAR. Dr. Tektonidou and Dr. Cervera reported having no relevant conflicts of interest.

Pregnancy management and outcomes have improved markedly for women with SLE over the past 2 decades, but there’s still progress to be made, research shows.

A retrospective cohort study led by rheumatologist Bella Mehta, MBBS, of the Hospital for Special Surgery in New York, and colleagues looked at data from the National Inpatient Sample database involving 93,820 pregnant women with SLE and 78,045,054 without SLE who were hospitalized in the United States between 1998 and 2015.

The results showed that over the 18-year study period, in-hospital maternal deaths per 100,000 admissions declined among patients with as well as those without SLE (442 vs. 13 for 1998-2000 and less than 50 vs. 10 for 2013-2015), although the decrease was greater in women with SLE (difference in trends, P less than .002).

Fetal mortality declined both for patients with SLE (268 deaths per 10,000 deliveries in 1998-2000 vs. 153 in 2013-2015) and those without SLE (72 deaths per 10,000 deliveries in 1998-2000 vs. 66 in 2013-2015).

“Although the decrease in fetal mortality seems somewhat greater in patients with SLE than those without it, the difference in trends is not statistically significant (P = .064),” the study authors noted in their paper, published in Annals of Internal Medicine.

Although patients with SLE in their study showed greater progress in rates of preeclampsia or eclampsia and length of stay, they still had worse outcomes in all measures when compared against women without SLE, the authors noted.

“Our study provides nationwide evidence that SLE pregnancy outcomes have become markedly better in the past 2 decades and continue to improve. However, SLE pregnancy risks remain high, and more work is needed to ensure good pregnancy outcomes among women with SLE,” they concluded.

Writing in an accompanying editorial, Megan E.B. Clowse, MD, of Duke University, Durham, N.C., noted that although the study findings of a progressive reduction in maternal mortality seemed very likely, the absolute decrease seen – from 140 maternal deaths per 100,000 births to fewer than 50 in 2013-2015 – warranted some reflection (Ann Intern Med. 2019;171:212-3. doi: 10.7326/M19-1667).

“SLE pregnancy management has not advanced within the past 5 years to an extent great enough to explain such a large drop in mortality,” she wrote.

There were also question marks around whether the NIS data should be used to analyze very rare events, such as maternal deaths in women with SLE. The SLE diagnosis in the database may also have included pregnancies in women who did not have SLE but instead had an elevated level of antinuclear antibody or lupus anticoagulant, which “may have diluted the frequency of poor outcomes,” Dr. Clowse wrote.

“For these reasons, I am concerned that the observed decline in maternal mortality may be an artifact, underestimating the ongoing risk of pregnancy for women with SLE,” Dr. Clowse wrote.

She added that recent analyses demonstrated that the use of hydroxychloroquine and aspirin in SLE pregnancy was not widespread.

“The inaugural reproductive health guidelines soon to be published by the American College of Rheumatology will have the potential to help expand state-of-the-art approaches to the management of pregnant women with SLE seen in everyday practice,” she concluded.

The study had no primary funding source and no conflicts of interest were declared. Dr. Mehta is supported by the C. Ronald MacKenzie Young Scientist Endowment Award. Dr. Clowse reported grants from GlaxoSmithKline and personal fees from UCB, both outside the submitted work.

The study had no primary funding source and no conflicts of interest were declared. Dr. Mehta is supported by the C. Ronald MacKenzie Young Scientist Endowment Award. Dr. Clowse reported grants from GlaxoSmithKline and personal fees from UCB, both outside the submitted work.

Pregnancy management and outcomes have improved markedly for women with SLE over the past 2 decades, but there’s still progress to be made, research shows.

A retrospective cohort study led by rheumatologist Bella Mehta, MBBS, of the Hospital for Special Surgery in New York, and colleagues looked at data from the National Inpatient Sample database involving 93,820 pregnant women with SLE and 78,045,054 without SLE who were hospitalized in the United States between 1998 and 2015.

The results showed that over the 18-year study period, in-hospital maternal deaths per 100,000 admissions declined among patients with as well as those without SLE (442 vs. 13 for 1998-2000 and less than 50 vs. 10 for 2013-2015), although the decrease was greater in women with SLE (difference in trends, P less than .002).

Fetal mortality declined both for patients with SLE (268 deaths per 10,000 deliveries in 1998-2000 vs. 153 in 2013-2015) and those without SLE (72 deaths per 10,000 deliveries in 1998-2000 vs. 66 in 2013-2015).

“Although the decrease in fetal mortality seems somewhat greater in patients with SLE than those without it, the difference in trends is not statistically significant (P = .064),” the study authors noted in their paper, published in Annals of Internal Medicine.

Although patients with SLE in their study showed greater progress in rates of preeclampsia or eclampsia and length of stay, they still had worse outcomes in all measures when compared against women without SLE, the authors noted.

“Our study provides nationwide evidence that SLE pregnancy outcomes have become markedly better in the past 2 decades and continue to improve. However, SLE pregnancy risks remain high, and more work is needed to ensure good pregnancy outcomes among women with SLE,” they concluded.

Writing in an accompanying editorial, Megan E.B. Clowse, MD, of Duke University, Durham, N.C., noted that although the study findings of a progressive reduction in maternal mortality seemed very likely, the absolute decrease seen – from 140 maternal deaths per 100,000 births to fewer than 50 in 2013-2015 – warranted some reflection (Ann Intern Med. 2019;171:212-3. doi: 10.7326/M19-1667).

“SLE pregnancy management has not advanced within the past 5 years to an extent great enough to explain such a large drop in mortality,” she wrote.

There were also question marks around whether the NIS data should be used to analyze very rare events, such as maternal deaths in women with SLE. The SLE diagnosis in the database may also have included pregnancies in women who did not have SLE but instead had an elevated level of antinuclear antibody or lupus anticoagulant, which “may have diluted the frequency of poor outcomes,” Dr. Clowse wrote.

“For these reasons, I am concerned that the observed decline in maternal mortality may be an artifact, underestimating the ongoing risk of pregnancy for women with SLE,” Dr. Clowse wrote.

She added that recent analyses demonstrated that the use of hydroxychloroquine and aspirin in SLE pregnancy was not widespread.

“The inaugural reproductive health guidelines soon to be published by the American College of Rheumatology will have the potential to help expand state-of-the-art approaches to the management of pregnant women with SLE seen in everyday practice,” she concluded.

MADRID – Repeated antinuclear antibody testing after a negative result has limited use for the diagnosis of ANA-associated rheumatologic conditions, according to data from a multicenter, retrospective analysis that considered a 7-year period.

Sara Freeman/MDEdge News

Considering more than 7,875 repeated ANA tests in 4,887 patients, “the vast majority of results didn’t change,” Ai Li Yeo, MBBS, a PhD candidate, rheumatologist, and infectious disease fellow at Monash University, Melbourne, reported at the European Congress of Rheumatology.

ANA tests were repeated between 2 and as many as 45 times in individual patients, she reported, but the results of 79% of these tests remained unchanged – 45% of tests were persistently negative and 34% persistently positive using a cutoff titer of 1:160.

“Our study showed that there was a very low yield in repeating an ANA test for the diagnosis of ANA-associated rheumatological conditions unless there was evidence of evolving multisystem clinical features,” Dr. Yeo said.

Indeed, the positive predictive value was just 0.01. “So for a hundred patients staring off with a negative ANA results that on repeat testing became positive, the probability is that one patient will have a new ANA-associated rheumatological condition diagnosis,” Dr. Yeo said.

“ANA testing is frequently performed and is part of the classification criteria for autoimmune conditions such as lupus and scleroderma,” she observed. However, the test provides no information on the severity or activity of the disease, and the value of serial monitoring for such conditions is unclear.

“Minimizing unnecessary tests is a global health economic priority,” Dr. Yeo said. She noted that there are multiple initiatives in place to try to open a dialog about using health care resources most effectively, such as ‘Choosing Wisely’ set up by the American Board of Internal Medicine (ABIM) Foundation.

The aim of the present analysis was to calculate the cost of repeated ANA testing and to see if any change in the ANA result was associated with new diagnoses of ANA-associated rheumatological conditions.

The analysis considered more than 36,700 tests that were performed on samples from more than 28,800 patients within the Monash Health tertiary health network between 2011 and 2018. Of these, 22,657 (62%) had given a negative result and 14,058 (38%) had given a positive result.

“Not surprisingly, the age of those who tested positive was significantly higher than those who tested negative,” Dr. Yeo said (52.6 vs. 48.9 years; P less than .001). There was also a higher number of women than men tested, and women more often tested positive.

Around one-fifth of tests performed were repeat tests, of which 511 (6.5%) changed from being negative to positive over a median of 1.71 years.

“A small percentage of people alternated between results,” Dr. Yeo acknowledged, with 9.4% of people going from a positive to a negative result; 10.5% moving from a negative to a positive result, and 1.9% going from positive to negative to positive.

With repeated tests, just five new diagnoses of ANA-associated rheumatologic conditions were made: two cases of systemic lupus erythematosus (SLE), one case of scleroderma, and two cases of undifferentiated connective tissue disease. There was a range of ANA titers and patterns and evolving clinical features of a multisystem disease.

Based on the direct costs of ANA testing in her health care system, not performing repeated tests could yield significant savings, Dr. Yeo said, a 21.4% reduction, in fact, based on this analysis. The cost of an ANA test in Australia ranges from 15 to 46 euros, making the cost of all tests in this analysis 564,745 euros. Taking away the cost of all the single ANA tests performed (443,209 euros) gives a potential cost saving of more than 121,000 euros, she said.

“We now have an opportunity to prevent unnecessary ANA testing, Dr. Yeo said. “Ultimately, our aim is to change behavior at the start of the ordering cycle by educating medical students and doctors about inappropriate test ordering.”

The majority of repeated tests had been ordered by nonrheumatologists (82% of cases), and Dr. Yeo said that rheumatologists ordered repeat tests in 11% of cases. However, there was little information available in this retrospective analysis as to why the tests had been repeated.

The research was picked as one of the six best clinical abstracts at the meeting, out of a total of almost 5,000 submitted abstracts.

Dr. Yeo reported having no conflicts of interest.

MADRID – RSLV-132, a novel drug that eliminates circulating nucleic acids, improved the symptoms of mental fatigue in patients with primary Sjögren’s syndrome (pSS) in a phase 2, double-blind, randomized, placebo-controlled “proof-of-concept” study.

The mental component of fatigue on the Profile of Fatigue (PRO-F) scale improved by 1.53 points among the patients given RSLV-132, while there was a worsening of 0.06 points in the placebo group (P = .046). Scores range from 0 to 7 on the PRO-F.

There were also improvements in some patient-reported outcomes, namely the EULAR pSS Patient Reported Index (ESSPRI) and the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue (FACIT-F), and improvement of neuropsychological measures of cognitive function, but none were statistically significant. All of these outcomes, including fatigue, were secondary outcomes of the study.

“Fatigue is a major issue for patients with Sjögren’s syndrome,” Wan-Fai Ng, MBChB, PhD, said in an interview at the European Congress of Rheumatology. Indeed, fatigue can be disabling in the majority of individuals, he added.

Currently, the best way to manage fatigue is to first ask about it, said Dr. Ng, who is professor of rheumatology at the Institute of Cellular Medicine at Newcastle University, Newcastle-upon-Tyne, England. He then checks for any underlying problem that could be better managed – sleep problems or anemia, for example – and optimizes treatment for any underlying disease. “I think many people would at least feel satisfied that people take the symptoms seriously.”

Dr. Ng and his coauthors investigated the effects of RSLV-132, a first-in-class human RNase fused to the human Fc domain of human immunoglobulin (Ig) G1, in the RESOLVE 132-04 study. This novel drug been designed to increase serum RNase activity to digest RNA-associated immune complexes, Dr. Ng and associates observed in their abstract. As a consequence of this, they say, activation of toll-like receptors and the production of interferon (IFN) is affected, as is B-cell proliferation and the production of autoantibodies – all mechanisms that are “key to pSS pathogenesis.”

The IFN pathway has been implicated in fatigue, Dr. Ng observed when he presented the RESOLVE 132-04 study’s findings, which involved 30 patients with pSS who had been treated for 3 months. Inclusion criteria were pSS as defined by the American-European Consensus Group 2002 criteria, anti-Ro antibody positivity, and increased expression of three IFN-regulated genes: HERC5, EPSTI1, and CMPK2. Exclusion criteria were the use of hydroxychloroquine, prednisolone at daily doses above 10 mg, and the use of biologic disease-modifying antirheumatic drugs.

Patients were randomized in a 3:1 ratio to receive either 10 mg/kg of RSLV-132 (n = 20) or placebo (n = 8) at weeks 0, 1, 2, and then every fortnight until week 12. Dr. Ng noted that although 30 patients were randomized, two patients had dropped out in the placebo group before they could be “treated.”

The primary endpoint was the change in the blood cell gene expression or serum protein levels indicative of reduced inflammation. The results indicated reductions in noncoding RNA molecules in patients who received RSLV-132 versus placebo, “consistent with the mode of action of the molecule.” In addition, “the majority of inflammatory markers were reduced,” Dr. Ng said.

Another finding showed a nonsignificant trend for improvement of 0.8 units in the physical component in the RSLV-132 group, compared against 0.06 units with placebo (P = .142).

Patients who received RSLV-132 reduced the time needed to complete the Digital Symbol Substitution Test by 16.4 s, compared with an increase of 2.8 s for placebo (P = .024).

Similar trends were observed for ESSPRI and FACIT-F scores.

These are very early data and clearly a bigger study would be needed before any conclusions could be drawn, Dr. Ng said in an interview. What these data suggest is that “maybe there is some way that we could manage fatigue, and we just need to go and explore that.”

RSLV-132 has also been studied in patients with systemic lupus erythematosus (Lupus. 2017;26:825-34).

The trial was sponsored by Resolve Therapeutics. Dr. Ng was an investigator in the trial and disclosed other research collaborations with electroCore, GlaxoSmithKline, and AbbVie. He also disclosed acting as a consultant for Novartis, GlaxoSmithKline, AbbVie, MedImmune, Pfizer, and Bristol-Myers Squibb.

It is well known that not everyone with SLE will respond well to rituximab, but that some will, first author Md Yuzaiful Md Yusof, MBChB, PhD, explained in an interview at the European Congress of Rheumatology.

Although data from clinical trials with rituximab in this patient setting have been essentially negative, the methodology of those trials has since been disputed, he observed. Indeed, subsequent data (Ann Rheum Dis. 2017;76:1829-36) have suggested that as many as 80% of patients could achieve a response with rituximab, particularly if there is complete B-cell depletion.

Previous researchers (Ann Rheum Dis. 2012;71:875-7) have shown that a polymorphism (158V) in the Fc gamma receptor IIIA (FCGR3A) gene is associated with the response to rituximab-based therapy in patients with rheumatoid arthritis (RA). This gene is important for antibody-dependent cellular-mediated cytotoxicity (ADCC).

The objective of the current study – an observational, prospective, longitudinal cohort study conducted in Leeds (England) – was therefore to see if the FCGR3A-158V polymorphism might influence response in patients with SLE.

“We were trying to find pretreatment biomarkers that could predict response to rituximab in SLE,” Dr. Md Yusof explained.

For the study, 85 patients who were treated with rituximab were assessed. The cohort was predominantly female (96%), with a mean age of 40 years. All of the patients had antinuclear antibodies, with just over half having anti–double-stranded DNA antibodies, and two-thirds having extractable nuclear antigens. One-third had low complement (C3/C4) levels.

Complete B-cell depletion occurred in 63% of patients with the FCGR3A-158V allele, a significantly higher rate than the 40% observed among those with 158 FF genotype (odds ratio, 2.73; P = .041). A significantly higher percentage of patients with the FCGR3A-158V allele also achieved a major BILAG (British Isles Lupus Assessment Group) response when compared against patients with the 158 FF variant (48% vs. 23%), with an odds ratio of 3.06 (P = .033).

Rituximab’s effect on NK cell-mediated B-cell killing may have played a key role in treatment response. Carrying the FCGR3A-158V allele was associated with greater degranulation activity versus the 158 FF variant.

Lastly, patients were more likely to remain on treatment with rituximab over a 10-year period if they had the FCGR3A-158V allele, compared with the 158 FF variant.

“These data suggest one mechanism by which patients with SLE might become resistant to the effects of rituximab, and could be used to guide therapy in the future,” Dr. Md Yusof suggested.

“Once this finding is validated, the clinical implication is that this genetic testing could be done prior to rituximab to identify those who will respond to therapy,” he postulated. “People with SLE who have this genetic variant with high affinity for rituximab are the ones that are better suited for rituximab therapy,” he added, otherwise a different CD20-directed antibody or alternative B-cell blockade therapies should be used.

The U.K. National Institute for Health Research funded the study. Dr. Md Yusof had no conflicts of interest to disclose; some coauthors disclosed ties to Roche, GlaxoSmithKline, and AstraZeneca, among other companies.

MADRID – The addition of leflunomide to standard glucocorticoids (GCs) in the treatment of IgG4-related disease increases the median duration of response, reduces the proportion of patients with relapse within 12 months, and permits GCs to be tapered, according to results of a randomized trial presented at the European Congress of Rheumatology.

“The rate of adverse events with the addition of leflunomide was numerically higher, but there were no significant differences in risks of any specific adverse event,” reported Feng Huang, MD, of the department of rheumatology at Chinese People’s Liberation Army General Hospital in Beijing.

GCs are highly effective in IgG4-related disease, which is an autoimmune process driven by elevated concentrations of the antibody IgG4 in the tissue of affected organs and in the serum. It has been described in a broad array of sites, including the heart, lung, kidneys, and meninges. It has been widely recognized only in the last 10 years, according to Dr. Huang. Although most patients respond to GCs, he said the problem is that about 50% of patients relapse within 12 months and more than 90% within 3 years.

This randomized, controlled study was conducted after positive results were observed with leflunomide in a small, uncontrolled pilot study published several years ago (Intern Med J. 2017 Jun;47[6]:680-9. doi: 10.1111/imj.13430). In this randomized trial, the objectives were to confirm that leflunomide extends the relapse-free period and has acceptable safety relative to GC alone.

Patients with confirmed IgG4-related disease were enrolled. Patients randomized to GC were started on 0.5 to 0.8 mg/kg per day. A predefined taper regimen was employed in those with symptom control. Those randomized to the experimental arm received GC in the same dose and schedule plus 20 mg/day of leflunomide.

The 33 patients in each group were well matched at baseline for age, comorbidities, and disease severity.

At the end of 12 months, 50% of those treated with GC alone versus 21.2% of those treated with GC plus leflunomide had relapse. That translated into a significantly higher hazard ratio (HR) for relapse in the GC monotherapy group (HR, 1.75; P = .034).

The mean duration of remission was 7 months on the combination versus 3 months on GC alone. Dr. Huang also reported a significantly higher proportion of complete responses in the group receiving the combination.

In addition, “more patients on the combination therapy were able to adhere to the steroid-tapering schedule without relapse,” Dr. Huang reported. The rate of 54.5% of patients on combination therapy who were able to reach a daily GC dose of 5 mg/day or less proved significantly higher than the 18.2% rate seen with GC alone (P = .002).


Adverse events were reported by 54% of those on the combination versus 42% of those on monotherapy, but this difference did not reach statistical significance. The biggest differences in adverse events were the proportions of patients with infections (18.2% vs. 12.1%) and elevated liver enzymes (12.1% vs. 3.0%), both of which were more common in the combination therapy group. Neither of these differences was statistically significant.

Of patients with relapses, the most common organs involved were the salivary gland, the pancreas, and the bile ducts, each accounting for relapse in five patients. Other organs in which relapse occurred included the lacrimal gland and the skin. There were three cases of relapse characterized by retroperitoneal fibrosis.

Over the course of follow-up, new-onset diabetes mellitus occurred in 21.2% and 27.3% of the combination and GC-only groups, respectively. This difference also did not reach statistical significance.

Although this study was small with an open-label design, Dr. Huang said the data strongly suggest that a combination of leflunomide and GC is superior to GC alone. Based on these results, he said a starting dose of 20 mg/day of leflunomide is a reasonable standard in this setting.

Dr. Huang and colleagues reported no potential conflicts of interest.

MADRID – Tocilizumab (Actemra) preserved lung function in patients with early systemic sclerosis (SSc), according to a secondary endpoint analysis of the phase 3, double-blind, randomized, controlled focuSSced trial.

After 48 weeks, a significantly lower proportion of patients treated with tocilizumab than placebo experienced any decline in lung function from baseline (50.5% versus 70.3% (P = .015), as defined by the percentage increase in predicted forced vital capacity (%pFVC). When only patients with interstitial lung disease (ILD) were considered, the respective percentages were 51.7% and 75.5% (P = .003).

In SSc-ILD patients, a clinically meaningful decline of 10% or more of the %pFVC in lung function was seen in 24.5% given placebo but in just 8.6% of those treated with tocilizumab.

“ILD is a major complication of scleroderma; it has high morbidity and mortality ... and it’s largely irreversible,” Dinesh Khanna, MD, said at the European Congress of Rheumatology.

“In this day and age, when we treat ILD, we wait for a patient to develop clinical ILD,” added Dr. Khanna, director of the scleroderma program at the University of Michigan, Ann Arbor. Clinical ILD can be defined by symptoms, abnormal pulmonary function tests, and marked abnormalities on high resolution computed tomography (HRCT) scans. He indicated that if improving ILD was not possible, then the next best thing would be to stabilize the disease and ensure there was no worsening in lung function.

As yet, there are no disease-modifying treatments available to treat SSc but there are “ample data that interleukin-6 plays a very important role in the pathogenesis of scleroderma,” Dr. Khanna observed. Tocilizumab is a humanized monoclonal antibody against the interleukin-6 receptor.

Data from the phase 2 faSScinate trial showed initial promise for the drug in SSc where a numerical, but not statistically significant, improvement in skin thickening was seen, and the results had hinted at a possible benefit on lung function (Lancet. 2016 Jun 25;387:2630-40).

However, in the phase 3 focuSSced trial, there was no statistically significant difference in the change from baseline to week 48 modified Rodnan skin score (mRSS) between tocilizumab and placebo, which was the primary endpoint. The least square mean change in mRSS was –6.14 for tocilizumab and –4.41 for placebo (P = .0983).

A total of 205 patients with SSc were studied and randomized, 1:1 in a double-blind fashion, to receive either a once-weekly, subcutaneous dose of 162 mg tocilizumab or a weekly subcutaneous placebo injection for 48 weeks.

For inclusion in the study, patients had to have SSc that met American College of Rheumatology and European League Against Rheumatism (EULAR) criteria and be diagnosed less than 60 months previously. Patients had to have an mRSS of 10-35 units and active disease with one or more of the following: C-reactive protein of 6 mg/L or higher; erythrocyte sedimentation rate of 28 mm/h or higher; and platelet count of330 x 10⁹ L.


“What was astonishing in the trial was that every patient had HRCT at baseline and at the end of the study,” Dr. Khanna reported. These scans showed that 64% of patients had evidence of ILD at baseline and that those treated with tocilizumab had less evidence of fibrosis at week 48 versus placebo, indicating a stabilization rather than worsening of disease.

A time to treatment failure analysis also favored tocilizumab over placebo, but there were no significant changes in patient-reported outcomes.

Dr. Khanna’s slides stated that “given that the primary endpoint for mRSS was not met, all other P values are presented for information purposes only and cannot be considered statistically significant despite the strength of the evidence.” During the Q&A after his presentation, he noted that it was unlikely that the study’s sponsors (Roche/Genentech) will now pursue a license for tocilizumab in SSc.

Nevertheless, Dr. Khanna concluded, “we have the opportunity, based on these data, to treat these patients early on, where you can preserve the lung function, which is a paradigm shift versus waiting for the lung function to decline, become clinically meaningful, significant, and then treat this patient population.”

Roche/Genentech sponsored the study. Dr. Khanna acts as a consultant to Roche/Genentech and eight other pharmaceutical companies. He owns stock in Eicos Sciences.

Dr. Khanna’s slides stated that “given that the primary endpoint for mRSS was not met, all other P values are presented for information purposes only and cannot be considered statistically significant despite the strength of the evidence.” During the Q&A after his presentation, he noted that it was unlikely that the study’s sponsors (Roche/Genentech) will now pursue a license for tocilizumab in SSc.

Nevertheless, Dr. Khanna concluded, “we have the opportunity, based on these data, to treat these patients early on, where you can preserve the lung function, which is a paradigm shift versus waiting for the lung function to decline, become clinically meaningful, significant, and then treat this patient population.”

MADRID – Tocilizumab (Actemra) preserved lung function in patients with early systemic sclerosis (SSc), according to a secondary endpoint analysis of the phase 3, double-blind, randomized, controlled focuSSced trial.

After 48 weeks, a significantly lower proportion of patients treated with tocilizumab than placebo experienced any decline in lung function from baseline (50.5% versus 70.3% (P = .015), as defined by the percentage increase in predicted forced vital capacity (%pFVC). When only patients with interstitial lung disease (ILD) were considered, the respective percentages were 51.7% and 75.5% (P = .003).

In SSc-ILD patients, a clinically meaningful decline of 10% or more of the %pFVC in lung function was seen in 24.5% given placebo but in just 8.6% of those treated with tocilizumab.

“ILD is a major complication of scleroderma; it has high morbidity and mortality ... and it’s largely irreversible,” Dinesh Khanna, MD, said at the European Congress of Rheumatology.

“In this day and age, when we treat ILD, we wait for a patient to develop clinical ILD,” added Dr. Khanna, director of the scleroderma program at the University of Michigan, Ann Arbor. Clinical ILD can be defined by symptoms, abnormal pulmonary function tests, and marked abnormalities on high resolution computed tomography (HRCT) scans. He indicated that if improving ILD was not possible, then the next best thing would be to stabilize the disease and ensure there was no worsening in lung function.

As yet, there are no disease-modifying treatments available to treat SSc but there are “ample data that interleukin-6 plays a very important role in the pathogenesis of scleroderma,” Dr. Khanna observed. Tocilizumab is a humanized monoclonal antibody against the interleukin-6 receptor.

Data from the phase 2 faSScinate trial showed initial promise for the drug in SSc where a numerical, but not statistically significant, improvement in skin thickening was seen, and the results had hinted at a possible benefit on lung function (Lancet. 2016 Jun 25;387:2630-40).

However, in the phase 3 focuSSced trial, there was no statistically significant difference in the change from baseline to week 48 modified Rodnan skin score (mRSS) between tocilizumab and placebo, which was the primary endpoint. The least square mean change in mRSS was –6.14 for tocilizumab and –4.41 for placebo (P = .0983).

A total of 205 patients with SSc were studied and randomized, 1:1 in a double-blind fashion, to receive either a once-weekly, subcutaneous dose of 162 mg tocilizumab or a weekly subcutaneous placebo injection for 48 weeks.

For inclusion in the study, patients had to have SSc that met American College of Rheumatology and European League Against Rheumatism (EULAR) criteria and be diagnosed less than 60 months previously. Patients had to have an mRSS of 10-35 units and active disease with one or more of the following: C-reactive protein of 6 mg/L or higher; erythrocyte sedimentation rate of 28 mm/h or higher; and platelet count of330 x 10⁹ L.


“What was astonishing in the trial was that every patient had HRCT at baseline and at the end of the study,” Dr. Khanna reported. These scans showed that 64% of patients had evidence of ILD at baseline and that those treated with tocilizumab had less evidence of fibrosis at week 48 versus placebo, indicating a stabilization rather than worsening of disease.

A time to treatment failure analysis also favored tocilizumab over placebo, but there were no significant changes in patient-reported outcomes.

An increased monocyte count at the time of diagnosis predicts poor outcomes among patients with idiopathic pulmonary fibrosis and other fibrotic diseases, including hypertrophic cardiomyopathy, systemic sclerosis, and myelofibrosis, according to research published in The Lancet Respiratory Medicine.

The data indicate that “a single threshold value of absolute monocyte counts of 0.95 K/mcL could be used to identify high-risk patients with a fibrotic disease,” said Madeleine K. D. Scott, a researcher at Stanford (Calif.) University, and coauthors. The results “suggest that monocyte count should be incorporated into the clinical assessment” and may “enable more conscientious allocation of scarce resources, including lung transplantations,” they said.

While other published biomarkers – including gene panels and multicytokine signatures – may be expensive and not readily available, “absolute monocyte count is routinely measured as part of a complete blood count, an inexpensive test used in clinical practice worldwide,” the authors said.

Further study of monocytes’ mechanistic role in fibrosis ultimately could point to new treatment approaches.

A retrospective multicenter cohort study

To assess whether immune cells may identify patients with idiopathic pulmonary fibrosis at greater risk of poor outcomes, Ms. Scott and her collaborators conducted a retrospective multicenter cohort study.

They first analyzed transcriptome data from 120 peripheral blood mononuclear cell samples of patients with idiopathic pulmonary fibrosis, which they obtained from the Gene Expression Omnibus at the National Center for Biotechnology Information. They used statistical deconvolution to estimate percentages of 13 immune cell types and examined their associations with transplant-free survival. Their discovery analysis found that estimated CD14+ classical monocyte percentages above the mean correlated with shorter transplant-free survival times (hazard ratio, 1.82), but percentages of T cells and B cells did not.

The researchers then validated these results using samples from patients with idiopathic pulmonary fibrosis in two independent cohorts. In the COMET validation cohort, which included 45 patients with idiopathic pulmonary fibrosis whose monocyte counts were measured using flow cytometry, higher monocyte counts were significantly associated with greater risk of disease progression. In the Yale cohort, which included 15 patients with idiopathic pulmonary fibrosis, the 6 patients who were classified as high risk on the basis of a 52-gene signature had more CD14+ monocytes than the 9 low-risk patients did.

In addition, Ms. Scott and her collaborators looked at complete blood count values in the electronic health records of 45,068 patients with idiopathic pulmonary fibrosis, systemic sclerosis, hypertrophic cardiomyopathy, or myelofibrosis in Stanford, Northwestern, Vanderbilt, and Optum Clinformatics Data Mart cohorts.
