Rheumatoid Arthritis

CHICAGO – After 52 weeks of blinded adalimumab, a switch to 48 weeks of unblinded baricitinib without an adalimumab washout period resulted in an uptick in rheumatoid arthritis control with no flares and no increase in serious adverse events in the phase 3 RA-BEYOND baricitinib long-term extension study, Michael E. Weinblatt, MD, reported at the annual meeting of the American College of Rheumatology. 

That’s information of practical clinical utility now that baricitinib, an oral inhibitor of Janus kinase subtypes 1 and 2, is approved as Olumiant for the treatment of moderate to severely active rheumatoid arthritis (RA). Perhaps even more interesting, however, is the way RA-BEYOND shined a spotlight on the high placebo response rate endemic to RA clinical trials, according to Dr. Weinblatt, professor of medicine at Harvard Medical School and codirector of clinical rheumatology at Brigham and Women’s Hospital, Boston.

He presented an analysis of two patient groups: 381 RA patients with moderately to severely active RA at baseline who were randomized to 52 weeks of double-blind baricitinib at 4 mg once daily in the previously reported phase 3 RA-BEAM trial (N Engl J Med. 2017 Feb 16;376[7]:652-62), after which they immediately enrolled in RA-BEYOND and were switched to 48 weeks of open-label, unblinded baricitinib; and 238 RA patients who were randomized to double-blind subcutaneous adalimumab (Humira) at 40 mg every 2 weeks in RA-BEAM before being switched to unblinded baricitinib in RA-BEYOND. All participants were on background oral methotrexate throughout.

Here’s the finding that captured Dr. Weinblatt’s attention: At the time of the switch, 28.2% of patients who’d been on blinded baricitinib for 52 weeks were nonresponders to the drug, meaning that after a full year of treatment they had a Clinical Disease Activity Index (CDAI) score greater than 10. Yet after a mere additional 4 weeks on the same drug in RA-BEYOND – this time unblinded as to their treatment – 23.4% of this group were transformed into responders, with low disease activity as defined by a CDAI of 10 or less. This finding speaks eloquently as to the power of the placebo effect. It’s a real issue for clinical trialists, the rheumatologist observed.

In the adalimumab-to-baricitinib group, 31.1% of patients were nonresponders to 52 weeks of blinded adalimumab. Four weeks after switching to open-label baricitinib, 29.7% of this group had a CDAI of 10 or less.

At week 48 of open-label baricitinib in RA-BEYOND, 54.2% of nonresponders to the 52 weeks of blinded baricitinib had become responders, as did 50% of nonresponders to a year of blinded adalimumab.

Taking a step back to describe the primary outcomes in RA-BEYOND, Dr. Weinblatt noted that at enrollment in RA-BEYOND, after 52 weeks on double-blind baricitinib, 71.8% of patients had a CDAI of 10 or less and 27% were in remission as defined by a CDAI of 2.8 or less. Subsequently, after 48 weeks on unblinded baricitinib, these rates climbed to 78.2% and 31.6%, respectively.

Similarly, in the adalimumab-to-baricitinib study arm, the low disease activity and remission rates at enrollment in RA-BEYOND were 68.9% and 24.4%, improving to 73.5% and 28.2% after 48 weeks on open-label baricitinib.

Scores on the SDAI (Simplified Disease Activity Index) and DAS28-ESR (Disease Activity Score based on 28 joints with erythrocyte sedimentation rate) followed suit in both groups.

During the 48 weeks of open-label baricitinib in RA-BEYOND, the incidence of herpes zoster was roughly 2.2% in both study arms, and the rate of adverse events leading to permanent drug discontinuation was 2.7%. During RA-BEYOND, serious infections occurred in 3.8% of the baricitinib-to-baricitinib group and 2.2% of the adalimumab-to-baricitinib group.

Dr. Weinblatt drew attention to the fact that the dose of baricitinib employed in RA-BEAM and RA-BEYOND was 4 mg/day, whereas the dose approved by the Food and Drug Administration is 2 mg/day.

The RA-BEAM and RA-BEYOND trials were sponsored by Eli Lilly. Dr. Weinblatt reported serving as a paid consultant to that pharmaceutical company and more than a dozen others.

Patients with tumor necrosis factor inhibitor–induced psoriasis could potentially be switched to a different drug class if they have moderate to severe skin eruption or mild skin eruption with an uncontrolled underlying disease such as inflammatory bowel disease, psoriasis, psoriatic arthritis, or rheumatoid arthritis, according to a new treatment algorithm proposed by researchers from Brigham and Women’s Hospital and Harvard Medical School in Boston.

The researchers outlined the prevalence of tumor necrosis factor–alpha inhibitor (TNFi)-induced psoriasis in a literature review of inflammatory bowel disease (IBD), psoriasis, psoriatic arthritis (PsA), and rheumatoid arthritis (RA) and identified an estimated rate of between 2.3% and 5% in patients with RA and between 1.6% and 2.7% in patients with IBD. Although there have been reports of TNFi-induced psoriasis in patients with psoriasis and PsA, the prevalence is unclear, they wrote in the Journal of Psoriasis and Psoriatic Arthritis.

The authors then created an algorithm to manage and treat TNFi-induced psoriasiform skin eruptions with decisions to continue therapy and “treat through” symptoms, switch to a different anti-TNF therapy, or switch to a different drug class based on severity of symptoms, whether the underlying disease is well controlled, and how patients with those underlying diseases have fared with those specific therapies or agents.

“We’ve shifted gears over the past decade, and we’ve gone from having very few agents and trying to keep patients desperately on one or two agents because we didn’t want to have to give up on them for their other comorbid disease, whether it was Crohn’s, colitis, RA, or whatever it may be,” senior author Joseph Merola, MD, director of the Center for Skin and Related Musculoskeletal Diseases at Brigham and Women’s Hospital, Boston, said in an interview. “We’re now in an area where we can have an algorithm like this, and we have so many more mechanistic options to move to.”

Dr. Merola, who is board certified in dermatology and rheumatology, said the algorithm is meant to “open a dialogue” with other specialists in different areas and raise awareness of treatments in related but separate fields. For diseases not often seen by more than one specialty, with the exception of psoriasis and PsA, he said that “the idea is to start a dialogue and increase communication between specialists.”

Dr. Merola noted that while the algorithm in many respects is meant to guide a physician in a specialty in appropriate medication decisions, at the same time he hopes that “it opens a dialogue and communication with the other specialty who tends to oversee this particular disease state or class of medicine to really work together to try to find the right drug for the right person.”

For patients with a mild skin eruption and a controlled underlying disease, the algorithm recommends a “treat through” approach by continuing anti-TNF therapy and treating psoriasis symptoms with topical steroids, ultraviolet therapy, methotrexate, cyclosporine, or acitretin, and to consider dapsone in cases of pustular psoriasis. However, the researchers noted that “treat through” studies have reported complete symptom resolution in 26%-41% of patients.

For patients with recalcitrant or worsening TNFi-induced psoriasis or patients with mild skin eruptions with an uncontrolled underlying disease, the researchers proposed considering switching to a different anti-TNF therapy, although studies have shown complete resolution of symptoms in only 5%-37% of patients.

If patients worsen from there, or if they have moderate to-severe skin eruption with uncontrolled underlying disease, they could be considered for switching to a different drug class and treated based on their underlying disease, along with treatment for psoriasis symptoms. This approach has been shown to completely resolve lesions in up to 64% of cases, they said. IBD patients could benefit from ustekinumab, vedolizumab, 6-mercaptopurine, or azathioprine as an alternative to anti-TNF therapy. Those patients with psoriasis should be considered for guselkumab, while ustekinumab, ixekizumab, secukinumab, and apremilast are effective treatments for patients with psoriasis and PsA. Patients with RA could receive treatment with tocilizumab, rituximab, abatacept, and tofacitinib, the authors wrote.

Methotrexate is effective for the control of pain produced by arthritis associated with Chikungunya virus infection, according to a retrospective review of outcomes in a series of 50 patients.

CDC/Cynthia Goldsmith

Joint pain and joint inflammation are commonly seen in the approximately 60% of patients who progress to the chronic phase of Chikungunya virus (CHIKV) infection, but there is no current consensus about how best to manage this complication, according to first author J. Kennedy Amaral, MD, of the department of infectious diseases and tropical medicine at the University of Minas Gerais (Brazil) and his colleagues, who published their experience in 50 patients in the Journal of Clinical Rheumatology.

In this study, the primary measure of efficacy was pain control because not all CHIKV infection patients with rheumatic symptoms demonstrate synovitis on radiological examination. The 50 patients included in this series all had joint symptoms persisting more than 12 weeks after onset of CHIKV infection.

All but four of the patients in this series were women. The mean age was 61.9 years. At baseline, 28 had a musculoskeletal disorder defined by presence of arthralgia, 11 had rheumatoid arthritis, seven had fibromyalgia, and four had undifferentiated polyarthritis.

On a 0-10 visual analog scale (VAS), the mean pain score at baseline was 7.7. All patients were initiated on a 4-week course of 7.5 mg of methotrexate administered with folic acid.

Four patients not examined after 4 weeks of treatment were excluded from analysis. Of those evaluated, 80% had achieved at least a 2-point reduction in VAS score, which is considered clinically meaningful. The mean reduction in VAS pain score at 4 weeks was 4.3 points (P less than .0001 vs. baseline). In 12 patients, symptoms were resolved, and they were not further evaluated.

Those with inadequate pain control at 4 weeks were permitted to begin a higher dose of methotrexate and to receive additional therapies. At 8 weeks, the reduction in VAS pain score was only modestly increased, reaching a mean 4.5-point reduction from baseline on a mean methotrexate dose of 9.2 mg/week. A substantial proportion of patients had added other medications, such as prednisone and hydroxychloroquine.

Only 20 patients had joint swelling and frank arthritis at baseline. In these, the mean swollen joint count decreased from 7.15 to 2.89 (P less than .0001). There was no further reduction at 8 weeks.

Over the course of the study, there was no evidence that methotrexate exacerbated CHIKV infection.

The data were collected retrospectively, and there was no control group, but the findings inform practitioners of the “possible benefit of low-dose methotrexate to treat both arthralgia and arthritis” in chronic CHIK-associated arthritis, according to Dr. Amaral and his coinvestigators.

The authors declared no potential conflicts of interest.

Methotrexate is effective for the control of pain produced by arthritis associated with Chikungunya virus infection, according to a retrospective review of outcomes in a series of 50 patients.

CDC/Cynthia Goldsmith

Joint pain and joint inflammation are commonly seen in the approximately 60% of patients who progress to the chronic phase of Chikungunya virus (CHIKV) infection, but there is no current consensus about how best to manage this complication, according to first author J. Kennedy Amaral, MD, of the department of infectious diseases and tropical medicine at the University of Minas Gerais (Brazil) and his colleagues, who published their experience in 50 patients in the Journal of Clinical Rheumatology.

In this study, the primary measure of efficacy was pain control because not all CHIKV infection patients with rheumatic symptoms demonstrate synovitis on radiological examination. The 50 patients included in this series all had joint symptoms persisting more than 12 weeks after onset of CHIKV infection.

All but four of the patients in this series were women. The mean age was 61.9 years. At baseline, 28 had a musculoskeletal disorder defined by presence of arthralgia, 11 had rheumatoid arthritis, seven had fibromyalgia, and four had undifferentiated polyarthritis.

On a 0-10 visual analog scale (VAS), the mean pain score at baseline was 7.7. All patients were initiated on a 4-week course of 7.5 mg of methotrexate administered with folic acid.

Four patients not examined after 4 weeks of treatment were excluded from analysis. Of those evaluated, 80% had achieved at least a 2-point reduction in VAS score, which is considered clinically meaningful. The mean reduction in VAS pain score at 4 weeks was 4.3 points (P less than .0001 vs. baseline). In 12 patients, symptoms were resolved, and they were not further evaluated.

Those with inadequate pain control at 4 weeks were permitted to begin a higher dose of methotrexate and to receive additional therapies. At 8 weeks, the reduction in VAS pain score was only modestly increased, reaching a mean 4.5-point reduction from baseline on a mean methotrexate dose of 9.2 mg/week. A substantial proportion of patients had added other medications, such as prednisone and hydroxychloroquine.

Only 20 patients had joint swelling and frank arthritis at baseline. In these, the mean swollen joint count decreased from 7.15 to 2.89 (P less than .0001). There was no further reduction at 8 weeks.

Over the course of the study, there was no evidence that methotrexate exacerbated CHIKV infection.

The data were collected retrospectively, and there was no control group, but the findings inform practitioners of the “possible benefit of low-dose methotrexate to treat both arthralgia and arthritis” in chronic CHIK-associated arthritis, according to Dr. Amaral and his coinvestigators.

The authors declared no potential conflicts of interest.

In RA, patients with predominantly tender joint counts were found to have lower levels of inflammation defined by ultrasound than those with predominantly swollen joints, according to an observational study that has implications for management decisions.

Suze777/Thinkstock

When patients do not achieve a remission defined by a composite disease activity score (CDAS) that includes tender joint counts, it suggests that inflammation persists, but this may be a “misinterpretation,” according to a report in Arthritis Care & Research by Hilde B. Hammer, MD, PhD, of the department of rheumatology at Diakonhjemmet Hospital, Oslo, and her associates.

In this observational study, 209 RA patients were evaluated at baseline and again at months 1, 2, 3, 6, and 12. The researchers compared 84 patients with predominantly tender joints, defined as tender-swollen joint count difference (TSJD) score of greater than zero, against 125 patients with predominantly swollen joints, defined as TSJD of zero or less.

Scores on specific CDAS measures, such as the Disease Activity Score based on 28 joints, the Clinical Disease Activity Index, and the Simplified Disease Activity Index, were significantly higher (P less than .001) at all visits in patients with predominantly tender joints, compared with those with predominantly swollen joints. Although laboratory markers, such as C-reactive protein and rheumatoid factor, were similar between groups, synovitis as scored with ultrasound assessment was significantly lower (P less than .001) among patients with predominantly tender joints than in those with predominantly swollen joints.


This disparity is important, according to the authors, who suggested that failure to reach a CDAS-defined remission solely on the basis of tender joints might complicate clinical assessment.

“Taking the high impact of CDAS levels in the treat-to-target management of RA into account, our results suggest a careful interpretation of CDAS levels in patients who have predominantly tender joints,” the authors reported.

Based on the evidence from this study, which found tender joints to be a positive predictor of CDAS and patient-reported outcomes but a negative predictor of ultrasound scoring of inflammation, “these results indicate that tender joints do not reflect the same pathology as found with ultrasound,” they wrote.

The research was supported by AbbVie, Pfizer, and Roche in the form of study grants awarded to the department of rheumatology at Diakonhjemmet Hospital via Dr. Hammer and two other authors. Dr. Hammer and the two other authors also reported financial relationships with those companies and others.

CHICAGO – Both methotrexate and canakinumab are anti-inflammatory drugs, but only canakinumab cut the incidence of cardiovascular disease events in a major clinical trial, CANTOS. A second big trial designed to parallel CANTOS tested methotrexate in roughly the same way and found it produced no cardiovascular disease benefit among high-risk patients.

Mitchel L. Zoler/MDedge News

The CANTOS (Canakinumab Anti-inflammatory Thrombosis Outcome Study) results with canakinumab and the new results with methotrexate “demonstrate that inflammation inhibition [with canakinumab] can significantly reduce cardiovascular event rates independent of lipid lowering and blood pressure reduction,” Paul M. Ridker, MD, said at the American Heart Association scientific sessions. But, “inhibition of the IL [interleukin]–1 beta to IL-6 to CRP [C-reactive protein] pathway of innate immunity appears to be important for atheroprotection,” and was something methotrexate couldn’t deliver, concluded Dr. Ridker, a professor of medicine at Harvard Medical School and director of the Center for Cardiovascular Disease Prevention at Brigham and Women’s Hospital in Boston.

The new results he reported showed that weekly treatment with a single, oral, 15- to 20-mg dose of methotrexate not only had no effect on cardiovascular events but also had no discernible impact on serum levels of IL-1beta (IL-1B), IL-6, or high sensitivity (hs) CRP, in contrast to canakinumab, which Dr. Ridker took as evidence that this inflammatory pathway links to the pathophysiology of atherosclerotic cardiovascular disease.

CIRT (Cardiovascular Inflammation Reduction Trial) randomized 4,786 patients at 417 centers in the United States or Canada. Enrolled patients had to have a history of an MI or documented multivessel coronary disease, and also had to have type 2 diabetes, metabolic syndrome, or both. All patients were maintained on optimized dosages of a statin, aspirin, a beta-blocker, and an angiotensin-converting enzyme inhibitor or angiotensin-receptor blocker. All patients also received 1 mg folate daily. Randomization assigned patients to either receive 15-20 mg methotrexate orally once a week or placebo.


CIRT stopped prematurely because of futility after a median follow-up of 2.3 years. At that time, the incidence of one of two primary endpoints, the combination of cardiovascular death, nonfatal MI, and nonfatal stroke was 3.46/100 person-years with methotrexate treatment and 3.43/100 person-years with placebo, a difference that was not statistically significant. The incidence of the second primary endpoint, which combined the first three types of events plus hospitalization for unstable angina that led to urgent coronary revascularization, occurred in 4.13/100 person-years with methotrexate and 4.31/100 person years with placebo, also a difference that was not statistically significant. Concurrently with this report, the results were published online (N Engl J Med. 2018 Nov 10. doi: 10.1056/NEJMoa1809798).

Analysis of inflammatory markers in the blood after 8 months on treatment showed that methotrexate had no effect on levels of IL-1B, IL-6, and hsCRP. Methotrexate’s lack of an effect on these markers as well as the absence of an effect on cardiovascular disease events contrasted sharply with results that Dr. Ridker and his associates reported a little more than a year earlier in CANTOS. The study’s investigators randomized 10,061 patients with a history of an MI and an elevated serum level of hsCRP, at least 2.0 mg/L. After a median follow-up of 3.7 years, treatment with 150 mg of canakinumab injected subcutaneously once every 3 months produced a 15% relative risk reduction in the combined rate of cardiovascular death, nonfatal MI, and nonfatal stroke, compared with patients treated with placebo, a statistically significant between-group difference (N Engl J Med. 2017 Sep 21;377[12]:1119-31). Canakinumab had no impact on LDL cholesterol levels, but lowered hsCRP levels by more than a third. Dr. Ridker and his associates designed the CIRT and CANTOS trials “in parallel,” he said, and the CIRT results using methotrexate provided a “neutral control” to complement the positive results from canakinumab in CANTOS,

Given its high cost, canakinumab (Ilaris) is not an obviously practical option for treating patients similar to those enrolled in CANTOS, so other candidate agents that inhibit the IL-1B, IL-6, CRP inflammatory pathway are now under study, Dr. Ridker said in an interview. The mechanism of methotrexate’s inhibition of inflammation is unknown, but clearly does not involve this pathway; it may be mediated by adenosine, Dr. Ridker suggested. Canakinumab has Food and Drug Administration approval for treating systemic juvenile idiopathic arthritis and a handful of additional, low-prevalence diseases. Novartis, the company that markets canakinumab, made a submission to the Food and Drug Administration seeking an indication for prevention of cardiovascular disease based on the CANTOS results, and the company said in October 2018 that the FDA denied this request.

The CIRT results also showed a previously unseen signal of a possible safety issue with the tested methotrexate regimen. The incidence of non–basal cell skin cancer was 0.65/100 person-years with methotrexate, compared with 0.24/100 person-years with placebo, a statistically significant difference. Until now, no one had reported a link like this and it requires further analysis, Dr. Ridker said.

CIRT received no commercial funding. Dr. Ridker has been a consultant to Corvidia, Inflazome, and Novartis; he has received research funding from Kowa and Novartis; and his work led to a patent held by Brigham and Women’s Hospital for inflammatory biomarkers licensed to Siemens and AstraZeneca.

CHICAGO – The selective Janus kinase 1 inhibitor filgotinib showed efficacy and safety for patients with rheumatoid arthritis in a phase 3 trial, and efficacy and safety for treating patients with psoriatic arthritis in results from a phase 2 study in two separate reports at the annual meeting of the American College of Rheumatology.

Mitchel L. Zoler/MDedge News

In the phase 3 study, treatment with filgotinib at an oral dosage of 200 mg once daily led to a 66% incidence of American College of Rheumatology 20 (ACR20) responses after 16 weeks of treatment in 147 patients with moderately to severely active rheumatoid arthritis (RA), compared with a 31% rate among 148 patients randomized to receive placebo, a statistically significant improvement for the study’s primary efficacy endpoint, Mark C. Genovese, MD, reported in a poster at the meeting. The rate of ACR20 responses among the 153 RA patients who received 100 mg/day filgotinib was 58%, reported Dr. Genovese, professor of medicine and director of the rheumatology clinic at Stanford (Calif.) University.

After 24 weeks of daily treatment, the longest duration studied in the trial, ACR20 rates were 69%, 55%, and 35% in the 200-mg, 100-mg, and placebo patients, respectively. Dr. Genovese also reported that after 24 weeks on treatment, the rates of patients achieving low disease activity measured by their disease activity score based on 28 joints and C-reactive protein level (DAS28-CRP) were 48%, 38%, and 21%, respectively, and the percentages of patients achieving complete remission at 24 weeks based on their DAS28-CRP scores were 31%, 26%, and 12%, respectively.

“We were incredibly fortunate to see such positive results. The drug worked very well in very-challenging-to-treat patients,” Dr. Genovese said in an interview. All of the RA patients enrolled in the study had not previously responded to or were intolerant of prior treatment with at least one biologic disease-modifying antirheumatic drug (DMARD), and almost a quarter of enrolled patients had failed prior treatment with at least three different biologic DMARDs. The number of biologic DMARDs a patient had previously received showed no relationship to how well patients responded to filgotinib, he noted.

Dr. Genovese also highlighted the relatively high percentage of patients who achieved low disease activity and remission. The 48% and 31% rates, respectively, of low disease activity and remission among patients treated with the higher filgotinib dosage for 24 weeks “is fairly impressive in patients who did not previously respond to a biologic DMARD,” the researcher said. These findings are similar to data previously reported for upadacitinib, another Janus kinase (JAK) inhibitor that, like filgotinib, is selective for the JAK1 receptor, noted Dr. Genovese, who also was the lead investigator for a phase 3 study of upadacitinib in RA patients (Lancet. 2018 June 23;391[10139]:2513-24).

The filgotinib data he presented came from the FINCH 2 (Filgotinib Versus Placebo in Adults With Active Rheumatoid Arthritis Who Have an Inadequate Response to Biologic Disease-Modifying Anti-Rheumatic Drug[s] Treatment) trial, which was run at 104 sites in 15 countries, including the United States. The results also showed a “favorable safety profile and stable laboratory parameters,” Dr. Genovese reported. Results from two additional phase 3 trials in RA patients are expected in 2019, he said.

Filgotinib studied in psoriatic arthritis

The separate, phase 2 study of filgotinib in patients with psoriatic arthritis (PsA) reported during the meeting showed safety “in line with previous reports without new safety signals” in a multicenter trial with 131 patients randomized to receive oral filgotinib 200 mg daily for 16 weeks or placebo, Philip J. Mease, MD, reported in a talk at the meeting. For the primary endpoint of achievement of ACR20 response after 16 weeks, the rate was 80% of the filgotinib-treated patients and 33% of patients in the placebo group, a statistically significant difference, said Dr. Mease, a rheumatologist at Swedish Medical Center in Seattle.

Mitchel L. Zoler/MDedge News

EQUATOR (A Study to Assess Efficacy and Safety of Filgotinib in Active Psoriatic Arthritis) enrolled patients at sites in seven European countries who had “very active” PsA and either a history of or current plaque psoriasis. All patients had to have a history of either insufficient response to or intolerance of at least one conventional synthetic DMARD. The enrollment criteria had no specifications for prior use of an anti–tumor necrosis factor drug, and about 15% of patients had used least one of these drugs. At entry, about three-quarters of patients were on treatment with a conventional synthetic DMARD and about a quarter received treatment with a glucocorticoid.

The results showed statistically significant benefits from filgotinib, compared with placebo, for several other measures of arthritis activity, as well as measures of psoriasis, enthesitis, and pain, Dr. Mease reported. He also highlighted a “lack of meaningful changes in hemoglobin” or other laboratory measures that, along with the efficacy findings, make filgotinib “a promising first step” for patients with PsA. Dr. Mease also noted that roughly concurrently with his report, a separate group of researchers published results from a phase 2 study of filgotinib in patients with ankylosing spondylitis that also found evidence for efficacy and safety during 12 weeks of treating 116 randomized patients (Lancet. 2018 Oct 22. doi: 10.1016/S0140-6736[18]32463-2).

FINCH 2 was sponsored by Galapagos and Gilead, the two companies developing filgotinib. Dr. Genovese has had financial relationships with Galapagos and Gilead and also with AbbVie, Lilly, and Pfizer. Dr. Mease has had financial relationships with Galapagos and Gilead and a dozen other companies.

CHICAGO – The selective Janus kinase 1 inhibitor filgotinib showed efficacy and safety for patients with rheumatoid arthritis in a phase 3 trial, and efficacy and safety for treating patients with psoriatic arthritis in results from a phase 2 study in two separate reports at the annual meeting of the American College of Rheumatology.

In the phase 3 study, treatment with filgotinib at an oral dosage of 200 mg once daily led to a 66% incidence of American College of Rheumatology 20 (ACR20) responses after 16 weeks of treatment in 147 patients with moderately to severely active rheumatoid arthritis (RA), compared with a 31% rate among 148 patients randomized to receive placebo, a statistically significant improvement for the study’s primary efficacy endpoint, Mark C. Genovese, MD, reported in a poster at the meeting. The rate of ACR20 responses among the 153 RA patients who received 100 mg/day filgotinib was 58%, reported Dr. Genovese, professor of medicine and director of the rheumatology clinic at Stanford (Calif.) University.

After 24 weeks of daily treatment, the longest duration studied in the trial, ACR20 rates were 69%, 55%, and 35% in the 200-mg, 100-mg, and placebo patients, respectively. Dr. Genovese also reported that after 24 weeks on treatment, the rates of patients achieving low disease activity measured by their disease activity score based on 28 joints and C-reactive protein level (DAS28-CRP) were 48%, 38%, and 21%, respectively, and the percentages of patients achieving complete remission at 24 weeks based on their DAS28-CRP scores were 31%, 26%, and 12%, respectively.

“We were incredibly fortunate to see such positive results. The drug worked very well in very-challenging-to-treat patients,” Dr. Genovese said in an interview. All of the RA patients enrolled in the study had not previously responded to or were intolerant of prior treatment with at least one biologic disease-modifying antirheumatic drug (DMARD), and almost a quarter of enrolled patients had failed prior treatment with at least three different biologic DMARDs. The number of biologic DMARDs a patient had previously received showed no relationship to how well patients responded to filgotinib, he noted.

Dr. Genovese also highlighted the relatively high percentage of patients who achieved low disease activity and remission. The 48% and 31% rates, respectively, of low disease activity and remission among patients treated with the higher filgotinib dosage for 24 weeks “is fairly impressive in patients who did not previously respond to a biologic DMARD,” the researcher said. These findings are similar to data previously reported for upadacitinib, another Janus kinase (JAK) inhibitor that, like filgotinib, is selective for the JAK1 receptor, noted Dr. Genovese, who also was the lead investigator for a phase 3 study of upadacitinib in RA patients (Lancet. 2018 June 23;391[10139]:2513-24).

The filgotinib data he presented came from the FINCH 2 (Filgotinib Versus Placebo in Adults With Active Rheumatoid Arthritis Who Have an Inadequate Response to Biologic Disease-Modifying Anti-Rheumatic Drug[s] Treatment) trial, which was run at 104 sites in 15 countries, including the United States. The results also showed a “favorable safety profile and stable laboratory parameters,” Dr. Genovese reported. Results from two additional phase 3 trials in RA patients are expected in 2019, he said.

Filgotinib studied in psoriatic arthritis

The separate, phase 2 study of filgotinib in patients with psoriatic arthritis (PsA) reported during the meeting showed safety “in line with previous reports without new safety signals” in a multicenter trial with 131 patients randomized to receive oral filgotinib 200 mg daily for 16 weeks or placebo, Philip J. Mease, MD, reported in a talk at the meeting. For the primary endpoint of achievement of ACR20 response after 16 weeks, the rate was 80% of the filgotinib-treated patients and 33% of patients in the placebo group, a statistically significant difference, said Dr. Mease, a rheumatologist at Swedish Medical Center in Seattle.

EQUATOR (A Study to Assess Efficacy and Safety of Filgotinib in Active Psoriatic Arthritis) enrolled patients at sites in seven European countries who had “very active” PsA and either a history of or current plaque psoriasis. All patients had to have a history of either insufficient response to or intolerance of at least one conventional synthetic DMARD. The enrollment criteria had no specifications for prior use of an anti–tumor necrosis factor drug, and about 15% of patients had used least one of these drugs. At entry, about three-quarters of patients were on treatment with a conventional synthetic DMARD and about a quarter received treatment with a glucocorticoid.

The results showed statistically significant benefits from filgotinib, compared with placebo, for several other measures of arthritis activity, as well as measures of psoriasis, enthesitis, and pain, Dr. Mease reported. He also highlighted a “lack of meaningful changes in hemoglobin” or other laboratory measures that, along with the efficacy findings, make filgotinib “a promising first step” for patients with PsA.

CHICAGO – Patients with newly diagnosed RA have subclinical abnormalities in vascular function that are favorably altered after they start to take disease-modifying anti-rheumatic drugs, Maya H. Buch, PhD, said at the annual meeting of the American College of Rheumatology.

Bruce Jancin/MDedge News

She presented a study of 71 treatment-naive patients with recently diagnosed RA and no history of cardiovascular disease. Patients were randomized to either etanercept plus methotrexate or methotrexate with treat-to-target escalation to triple nonbiologic disease-modifying antirheumatic drug therapy by week 12. Patients in the latter group were switched to etanercept plus methotrexate at week 24 if at that point they had a Disease Activity Score 28 of 2.6 or more.

All participants underwent cardiovascular MRI at baseline and again after 1 and 2 years in order to measure change in aortic stiffness, the primary study endpoint chosen because it is clinically meaningful and can reliably and reproducibly be measured by MRI.

The study was designed to shed light on possible mechanisms for the epidemiologic observation that effective treatment with methotrexate and/or tumor necrosis factor (TNF) inhibitors curbs the excess risk of cardiovascular events that accompanies RA. The thinking is that abnormal aortic distensibility represents an early harbinger of the increased cardiovascular risk associated with this form of inflammatory arthritis, explained Dr. Buch, professor of rheumatology at the University of Leeds (England) and section head of clinical and translational rheumatology at the Leeds Institute of Rheumatic and Musculoskeletal Medicine.

The mean aortic distensibility at baseline, when the study population was treatment naive, was 2.99 x 10^–3 mm Hg^–1. This value is abnormally low when compared with values seen in healthy age- and sex-matched controls. After 1 year of treatment, however, mean aortic distensibility improved significantly to 3.59 x 10^–3 mm Hg^–1. This improvement was maintained at year 2, when the mean value was 3.55.

Interestingly, neither treatment response status or disease activity was associated with the improvement in aortic stiffness. However, in a prespecified exploratory comparison between the 20 responders to etanercept plus methotrexate and the 10 responders to first-line methotrexate who never received etanercept, the group on biologic therapy had a 16% greater improvement in aortic distensibility at 1 year.

“It’s not a statistically significant difference. The study wasn’t powered for that,” she said in an interview. “But these data suggest that an anti-TNF treatment strategy may confer additional benefit. Of course, that will need to be confirmed in a larger trial. And if it is confirmed, it would suggest a role for etanercept plus methotrexate in personalizing tailored therapy in early RA patients at particularly high cardiovascular risk.”

Dr. Buch reported receiving funding from Pfizer, Roche, UCB, AbbVie, Sanofi, Eli Lilly, and Sandoz, but reported having no financial conflicts of interest regarding this study, which was sponsored by the U.K. National Institute for Healthcare Research.

Patients with rheumatoid arthritis and a high multibiomarker disease activity (MBDA) score were more likely than were patients with low scores to add or switch to biologics or JAK inhibitors, according to a study on the uptake and influence of MBDA testing among rheumatologists and patients.

“While we cannot provide certainty that the main reason that clinicians switched therapies was the MBDA test result, we note that the median time to add or switch to a new RA treatment was 1-2 months after testing, lending plausibility to the MBDA test being influential in this decision,” wrote Jeffrey R. Curtis, MD, of the division of clinical immunology and rheumatology at the University of Alabama at Birmingham, and his coauthors. Their report is in The Journal of Rheumatology.

The researchers analyzed Medicare data from 60,596 RA patients who had taken at least one MBDA (Vectra DA) test. Patients with high MBDA scores who were not taking biologics or a JAK inhibitor were most likely to begin one of the two treatments, at 19.7%, compared with 11.8% for a moderate MBDA score and 9.0% for a low score. For patients already receiving those treatments, the proportion adding or switching was 13.5% for high, 8.3% for moderate, and 5.2% for low MBDA scores. In addition, patients with high MBDA scores who added a new medication and saw no improvement in score were prone to see treatment fail; the likelihood of failure in that scenario was 61% higher (OR = 1.61; 95% confidence index, 1.27-2.03) than in patients whose score improved to low or moderate.

The authors acknowledged that their study did not randomize clinicians nor gather data as to why the tests were ordered, which made it “difficult to assess the incremental value of the information provided by testing above and beyond clinical measurement, or to know whether the treatment changes were appropriate.” However, they also noted the MBDA score’s value as a complement to clinical assessment and an indicator of disease activity, suggesting “ongoing clinical trials and forthcoming data (e.g., MBDA to refine the patient-specific predicted risk of future radiographic damage) will be useful to further define the optimal role for the MBDA test in clinical practice to optimize longer-term outcomes.”

The study was partly supported by Myriad Genetics, which owns Crescendo Bioscience, the company that markets the MBDA test known as Vectra DA. Dr. Curtis receives support from the National Institutes of Health and the Patient-Centered Outcomes Research Institute, along with research grants and/or consulting fees from Amgen, Bristol-Myers Squibb, Corrona, Janssen, Myriad Genetics, Pfizer, and UCB.

CHICAGO – Nearly two-thirds of rheumatoid arthritis patients who achieved remission or low disease activity on tocilizumab plus low-dose prednisone were able to taper off prednisone treatment while remaining in at least low disease activity in a multicenter, randomized trial with 259 patients.

Mitchel L. Zoler/MDedge.com

The results also showed that rheumatoid arthritis (RA) patients randomized to maintain prednisone treatment at 5 mg/day along with tocilizumab fared even better. After 24 weeks of the glucocorticoid-tapering regimen, by which time patients in the tapered arm had their prednisone dosage down to 0 mg, the average change from baseline in their disease activity score 28 with erythrocyte sedimentation rate (DAS28-ESR) was an increase of 0.538, compared with an average drop of 0.075 among untapered patients, a statistically significant difference for the study’s primary endpoint, Gerd R. Burmester, MD, said at the annual meeting of the American College of Rheumatology.

But while the results definitively showed that RA patients treated with the anti-interleukin 6 agent tocilizumab (Actemra) as their primary drug benefited from continued, additional treatment with low-dose prednisone, the results also showed that many patients could come off prednisone without immediate downside. Among the 131 randomized to a forced taper and eventual prednisone discontinuation, 85 (65%) went through this process without flaring and maintained at least low disease activity and sometimes remission, said Dr. Burmester, a professor and director of rheumatology and clinical immunology at Charité Hospital in Berlin. In contrast, 99 of 128 patients (77%) maintained on tocilizumab plus 5 mg/day of prednisone were free from any flares and had at least low disease activity after 24 weeks, a statistically significant between-group difference.

These findings “have potential to inform clinical practice and aid in conversations with patients. RA patients who achieve at least low disease activity while receiving tocilizumab and long-term glucocorticoid treatment at 5 mg/day should be considered for tapering of their glucocorticoid dosage, ideally targeting discontinuation,” Dr. Burmester said.

Addressing a comment from the audience that it’s common knowledge that patients who are well controlled on a potent immunomodulating drug like tocilizumab can often successfully wean off a glucocorticoid, Dr. Burmester insisted that it was important to show this in a randomized, blinded trial.

“When they discontinue [a glucocorticoid] patients can develop myalgias or other symptoms and we haven’t known whether that was real or psychological. In this study patients did not know whether they were being discontinued, so the psychological element was gone,” he said. The new findings confirm in a rigorous way that “we could discontinue a substantial number of patients who probably no longer need a glucocorticoid. It’s an important discussion” for clinicians to have with patients.

The SEMIRA (Steroid Elimination in RA) trial enrolled 68 patients who had already begun tocilizumab treatment and 191 patients new to the drug who had a 24-week run-in on tocilizumab, all of whom also received 5 mg prednisone daily. The trial included 46 sites in five European countries plus Russia and Tunisia. During the main 24-week phase of the study, 128 patients remained on their entry regimen of tocilizumab and prednisone, with 112 completers; 131 others went through a forced taper that culminated in no prednisone administered during the final 8 weeks, with 114 completers. Patients averaged about 54 years old, and just over three-quarters were women. Almost two-thirds of patients also received a nonbiologic disease-modifying antirheumatic drug.

A time-trend analysis of changes in DAS28-ERS showed that, while the difference in change from baseline in disease activity between the two treatment arms separated early in the taper process, the biggest uptick in DAS28-ESR in the patients coming off prednisone occurred once the final 1 mg/day dose was stopped.

The results also showed that tapering led to a statistically significant rise in the clinical disease activity index for RA, compared with that seen with not tapering, and tapering also was linked significantly with an increase in serum markers of bone turnover. The safety analysis showed no striking between-group differences in adverse events and in serious adverse events, and no patients developed confirmed adrenal insufficiency that required replacement therapy.

CHICAGO – Nearly two-thirds of rheumatoid arthritis patients who achieved remission or low disease activity on tocilizumab plus low-dose prednisone were able to taper off prednisone treatment while remaining in at least low disease activity in a multicenter, randomized trial with 259 patients.

The results also showed that rheumatoid arthritis (RA) patients randomized to maintain prednisone treatment at 5 mg/day along with tocilizumab fared even better. After 24 weeks of the glucocorticoid-tapering regimen, by which time patients in the tapered arm had their prednisone dosage down to 0 mg, the average change from baseline in their disease activity score 28 with erythrocyte sedimentation rate (DAS28-ESR) was an increase of 0.538, compared with an average drop of 0.075 among untapered patients, a statistically significant difference for the study’s primary endpoint, Gerd R. Burmester, MD, said at the annual meeting of the American College of Rheumatology.

But while the results definitively showed that RA patients treated with the anti-interleukin 6 agent tocilizumab (Actemra) as their primary drug benefited from continued, additional treatment with low-dose prednisone, the results also showed that many patients could come off prednisone without immediate downside. Among the 131 randomized to a forced taper and eventual prednisone discontinuation, 85 (65%) went through this process without flaring and maintained at least low disease activity and sometimes remission, said Dr. Burmester, a professor and director of rheumatology and clinical immunology at Charité Hospital in Berlin. In contrast, 99 of 128 patients (77%) maintained on tocilizumab plus 5 mg/day of prednisone were free from any flares and had at least low disease activity after 24 weeks, a statistically significant between-group difference.

These findings “have potential to inform clinical practice and aid in conversations with patients. RA patients who achieve at least low disease activity while receiving tocilizumab and long-term glucocorticoid treatment at 5 mg/day should be considered for tapering of their glucocorticoid dosage, ideally targeting discontinuation,” Dr. Burmester said.

Interstitial lung disease (ILD) is becoming more prevalent in patients with RA while shortening survival and leading to substantial health care costs, according to a retrospective study of RA-ILD prevalence, incidence, costs, and mortality.

“To our knowledge, this is the first study to describe the incidence and prevalence of RA-ILD among the general population and to estimate costs among U.S. patients with RA-ILD,” wrote lead author Karina Raimundo, principal health economist at Genentech, and her coauthors in the Journal of Rheumatology.

The study reviewed data from the Truven Health MarketScan Commercial and Medicare Supplemental health insurance databases, along with linking a subset of patients to the Social Security Administration Death Index to determine mortality. From 2004 to 2013, with the number of patients ranging from 892 to 3,232 per year, yearly prevalence estimates ranged from 3.2 (95% confidence interval, 3.0-3.4) to 6.0 (95% CI, 5.7-6.2) RA-ILD cases per 100,000 people. Yearly incidence ranged from 2.7 (95% CI, 2.5-2.9) to 3.8 (95% CI, 3.5-4.0) cases per 100,000 people.

While incidence was relatively stable, prevalence increased over the 10-year period. The authors noted that increased prevalence suggests improved survival of RA-ILD patients but were unable to definitively state why, with explanations ranging from more effective therapies to earlier diagnosis of the disease. “Our data do not allow more in-depth evaluation of this issue, and it merits further analysis.”

In addition, they found that average yearly costs across all study years ranged from $40,941 (standard deviation, $55,682) to $51,849 (SD, $77,125), with the main cost drivers being inpatient admissions, outpatient services, and outpatient pharmacy. By the 5-year mark of first diagnosis, 35.9% of RA-ILD patients who could be linked to the SSDI had died; those patients – with a mean age of 65 years – also had a median survival of 7.8 years (95% CI, 7.1-8.3). Generally, a 65-year-old person in the United States would be expected to live for 19 more years.

The authors acknowledged the study’s limitations, including reliance on administrative claims data, subsequent misclassification of RA-ILD status, a lack of information on cause of death, and an underestimation of mortality caused by the inability to link all patients to the Social Security Administration Death Index.

The study was funded by Genentech and F. Hoffmann–La Roche. No other conflicts of interest were reported.
