Low-dose methotrexate trial pins down adverse event rates
A new study has found an elevated risk of some adverse events in patients treated with low-dose methotrexate, compared with patients treated with placebo.
“The data presented here provide an important source of new evidence to improve the monitoring guidelines and safe prescribing of LD-MTX [low-dose methotrexate],” wrote Daniel H. Solomon, MD, of Brigham and Women’s Hospital and Harvard Medical School in Boston, and coauthors. The study was published in Annals of Internal Medicine.
To determine the rates of adverse events (AEs) among LD-MTX users, along with assessing the risks of certain predefined AEs, the researchers enrolled 6,158 patients in the Cardiovascular Inflammation Reduction Trial (CIRT) and randomized 4,786 of those patients to two groups: those receiving LD-MTX (n = 2,391) and those receiving placebo (n = 2,395). The median dose was 15 mg per week, and median follow-up was 23 months. All participants in CIRT had a history of cardiovascular disease, along with diabetes or metabolic syndrome. Just over 81% of the participants were male, and nearly 85% were white. Their median age was nearly 66 years.
Of the participants in the LD-MTX group, 2,156 (90.2%) had an AE and 2,080 (87.0%) had an AE of interest, which included infectious, hematologic, pulmonary, hepatic, cancerous, and gastrointestinal AEs. Of the participants in the placebo group, 2,076 (86.7%) had an AE and 1,951 (81.5%) had an AE of interest. As such, the relative rate of an AE of interest was 17% higher in the LD-MTX group (hazard ratio, 1.17; 95% confidence interval, 1.10-1.25).
In regard to specific types of AEs, the rates of gastrointestinal (HR, 1.23; 95% CI, 1.03-1.47), pulmonary (HR, 1.42; 95% CI, 1.14-1.77), infectious (HR, 1.15; 95% CI, 1.01-1.30) and hematologic (HR, 1.22; 95% CI, 1.11-1.34) were higher for participants in the LD-MTX group. Five cases of cirrhosis were found in the LD-MTX group, compared with none in the placebo group; none of the patients with cirrhosis had severe liver test abnormalities before their diagnosis. While the risk of cancer overall was not elevated in the LD-MTX group, 53 participants in that group developed skin cancer, compared with 26 in the placebo group (HR, 2.04; 95% CI, 1.28-3.26). Renal AEs were among the few that decreased in LD-MTX users (HR, 0.85; 95% CI, 0.78-0.93).
“Methotrexate has become the standard of care for RA patients,” Dr. Solomon said in an interview, “and because it worked so well, we accepted it without large placebo-controlled trials and without a precise understanding of the risk factors for AEs. Until this study, our evidence basis for the side-effect profile was relatively weak.
“We had a limited data set but decades of experience,” he added. “Now we have better evidence, for example, that methotrexate is associated with elevations in liver function tests. We even found five cases of cirrhosis. And the people who developed cirrhosis didn’t have severe test abnormalities; just minor ones over many months. So now we have a better understanding of the potential impact of minor, yet chronic abnormalities.”
Dr. Solomon and coauthors acknowledged their study’s limitations, including CIRT not including patients with systemic rheumatic disease and the possibility that participants did not report AEs that occurred in between routine study visits. In addition, although the median follow-up of nearly 2 years was longer than in other LD-MTX trials, they noted that “it may still be too short to observe some AEs that require long-term exposure.”
Dr. Solomon and colleagues should be commended for undertaking a long-awaited randomized, placebo-controlled trial that adds much-needed insight into how and when to monitor patients being treated with MTX, Vivian P. Bykerk, MD, of the Hospital for Special Surgery and Weill Cornell Medical College in New York, wrote in an editorial (Ann Intern Med. 2020 Feb 17. doi: 10.7326/M20-0435).
Dr. Bykerk noted that although the results may not be applicable to patients with RA and other inflammatory arthritides who are treated with MTX – RA patients in particular are younger, more often female, have lower rates of diabetes, and usually receive higher doses than those used in CIRT — the risk estimates from the CIRT study are “largely congruent with those expected in MTX-treated patients with rheumatic diseases.”
Regardless, she emphasized that this is a step in a much-needed direction, reminding physicians that “MTX use has inherent risks” and that its AEs, although infrequent, are clinically serious.
The National Institutes of Health funded the study. Various authors reported receiving grants from the National Heart, Lung, and Blood Institute, along with grants, research support, and personal fees from numerous pharmaceutical companies before and during the study. Dr. Bykerk reported receiving personal fees, grants, and nonfinancial support from pharmaceutical companies, foundations, and the NIH.

Nonspecific musculoskeletal symptoms might indicate early PsA
People with psoriatic arthritis can be symptomatic for years before the condition is diagnosed, according to two recent reports.
There are no reliable diagnostic biomarkers, and sometimes patients have vague symptoms with only minimal physical findings, which makes it hard for physicians to recognize the problem and refer to rheumatology.
In the meantime, the longer it takes to diagnose psoriatic arthritis (PsA) and treat it properly, the worse off patients are when it’s finally caught. They “present with a greater rate of clinical progression and worse physical function, compared with patients with an undelayed diagnosis,” and more radiographic joint damage, according to investigators led by rheumatologist Alexis Ogdie, MD, an associate professor of medicine at the University of Pennsylvania, Philadelphia.
Dr. Ogdie’s study in BMC Rheumatology, and a second one from Arthritis Care & Research, both described the early phase of psoriatic arthritis, before formal diagnosis, to help with early recognition.
Delay associated with misdiagnosis
Dr. Ogdie’s team surveyed 203 adults with PsA – average age of 52 years, mostly white, and over 80% women – about their diagnosis history. The time between seeking medical attention for PsA-related symptoms and receiving a diagnosis was less than 6 months for 69 participants, 6 months to 4 years for 68, and 5 years or more for 66.
Typical symptoms, like joint pain, swollen joints, reduced range of motion, and dactylitis, were associated with quicker diagnosis. Turning early to dermatologists and rheumatologists – instead of general practitioners, orthopedics, chiropractors, and others – sped diagnosis, as well. People diagnosed within 6 months also tended to be slightly older, were less likely to be disabled or unemployed, have more education, and were more likely to make $100,000 per year or more.
Vaguer symptoms, such as stiffness, fatigue, and enthesitis-associated foot pain, delayed diagnosis. The longer PsA went unrecognized, the more likely people were to be misdiagnosed with osteoarthritis, psychosomatic disorders, and other problems.
“Increased recognition of heterogeneous symptoms associated with PsA, as well as understanding existing diagnostic barriers, may lead to prompt diagnosis and initiation of appropriate treatment that may improve outcomes,” the investigators concluded.
A prodromal phase
In the Arthritis Care & Research study, investigators led by Lihi Eder, MD, PhD, codirector of the cardio-rheumatology program at Women’s College Hospital, Toronto, used health records and databases to compare primary care histories of 462 Canadian PsA patients in the 5 years before they were diagnosed with 2,310 age- and sex-matched controls without PsA and treated by the same family physicians. The mean age in the study was 54 years, and just over half the subjects were women. Socioeconomic status and rurality were similar between the two groups.
The mean time from the initial primary care visit for a musculoskeletal complaint to rheumatology referral was 513 days among PsA patients, “which was substantially longer than for other inflammatory arthritic conditions, such as rheumatoid arthritis,” Dr. Eder and associates noted.
PsA patients were more than twice as likely to visit primary care for nonspecific musculoskeletal issues in the year before their diagnosis, and more likely in the 5 years prior. The odds of visits to musculoskeletal specialists, joint injections, joint imaging, and ED visits, was also higher as early as 5 years before PsA recognition, and hinted at the impending diagnosis.
“Our study characterized a prediagnosis period in PsA and supports the notion that a prodromal PsA phase occurs in a significant proportion of patients. ... This pattern reveals some of the underlying causes of diagnosis delays of PsA and highlights the need for diagnostic strategies and novel reliable biomarkers to aid in early diagnosis of PsA,” the investigators concluded.
Dr. Ogdie and colleagues suggested that community case searches, public awareness programs, patient education, and referral guidelines for primary care providers might help. They also suggested greater use of validated screening tools, such as the Psoriasis Epidemiology Screening Tool, in primary care.
Dr. Eder had no disclosures, and her study was funded by the Canadian Rheumatology Association. Dr. Ogdie’s study was funded by Novartis, maker of secukinumab (Cosentyx), which is indicated for PsA. She is a consultant for Novartis and has received grant support from the company. One author is an employee.

Tildrakizumab signals safe for pregnant psoriasis patients
A post hoc analysis of .
“Although contraception in female patients of childbearing age was mandatory before initiation of and during tildrakizumab therapy, some pregnancies occurred during the tildrakizumab clinical development program as protocol violations,” wrote Kathleen Haycraft, MD, of Riverside Dermatology & Spa, Hannibal, Mo., and colleagues.
Tildrakizumab (Ilumya), an interleukin-23 antagonist, was approved in 2018 by the Food and Drug Administration for treatment of adults with moderate to severe plaque psoriasis who are candidates for systemic therapy or phototherapy. Effects on birth outcomes or on neonates exposed during pregnancy have not been studied, the researchers said.
“Tildrakizumab plasma half-life after subcutaneous administration is approximately 25 days; therefore, tildrakizumab administered even in the first trimester may cross the placental barrier,” they noted.
In a research letter published in the British Journal of Dermatology, the investigators reviewed data from nine phase 1, 2, and 3 clinical trials and identified 528 women of childbearing age who received tildrakizumab. Fourteen pregnancies were reported among these women: six from a contraceptive failure, and eight for lack of contraception use. (One of the phase 1 trials was in patients with Crohn’s disease, which included one of the pregnancies; the rest were in patients with psoriasis.)
The 14 pregnancy outcomes included 2 spontaneous abortions (14.3%), 4 elective abortions (28.6%), and 8 live births (57.1%), which included 1 premature birth, with “no identifiable congenital anomalies,” the authors wrote. The longest duration of exposure to tildrakizumab in a pregnant woman was 1,196 days; this pregnancy resulted in a premature live birth at 36 weeks with no anomalies. The spontaneous abortion rate was similar to the rate in the general population, which is 12%-15%, the authors noted.
While the study “adds to the existing evidence on the outcomes of biologic treatment of psoriasis,” the findings were limited by several factors including the small number of pregnancies, short duration of exposure to tildrakizumab, variations in dosing, and lack of controls, the researchers noted. “Additional data from a larger population following tildrakizumab exposure are required to fully evaluate the safety and tolerability of tildrakizumab treatment during pregnancy,” they said. In the meantime, they advised women of childbearing age with psoriasis to continue to avoid pregnancy and follow practice guidelines for contraceptive use while taking the biologic therapy.
The studies were supported by Merck Sharp & Dohme, a Merck & Co. subsidiary; analyses were supported by Sun Pharmaceutical Industries. Lead author Dr. Haycraft disclosed relationships with companies including Sun, Celgene, Lilly, Novartis, Ortho-Derm, and Pfizer. Other authors disclosed relationships with Novartis, Celgene, Ortho Dermatologics, Janssen, and Merck; two authors are Sun employees.

“Tildrakizumab plasma half-life after subcutaneous administration is approximately 25 days; therefore, tildrakizumab administered even in the first trimester may cross the placental barrier,” they noted.
In a research letter published in the British Journal of Dermatology, the investigators reviewed data from nine phase 1, 2, and 3 clinical trials and identified 528 women of childbearing age who received tildrakizumab. Fourteen pregnancies were reported among these women: six from a contraceptive failure, and eight for lack of contraception use. (One of the phase 1 trials was in patients with Crohn’s disease, which included one of the pregnancies; the rest were in patients with psoriasis.)
The 14 pregnancy outcomes included 2 spontaneous abortions (14.3%), 4 elective abortions (28.6%), and 8 live births (57.1%), which included 1 premature birth, with “no identifiable congenital anomalies,” the authors wrote. The longest duration of exposure to tildrakizumab in a pregnant woman was 1,196 days; this pregnancy resulted in a premature live birth at 36 weeks with no anomalies. The spontaneous abortion rate was similar to the rate in the general population, which is 12%-15%, the authors noted.
While the study “adds to the existing evidence on the outcomes of biologic treatment of psoriasis,” the findings were limited by several factors including the small number of pregnancies, short duration of exposure to tildrakizumab, variations in dosing, and lack of controls, the researchers noted. “Additional data from a larger population following tildrakizumab exposure are required to fully evaluate the safety and tolerability of tildrakizumab treatment during pregnancy,” they said. In the meantime, they advised women of childbearing age with psoriasis to continue to avoid pregnancy and follow practice guidelines for contraceptive use while taking the biologic therapy.
The studies were supported by Merck Sharp & Dohme, a Merck & Co. subsidiary; analyses were supported by Sun Pharmaceutical Industries. Lead author Dr. Haycraft disclosed relationships with companies including Sun, Celgene, Lilly, Novartis, Ortho-Derm, and Pfizer. Other authors disclosed relationships with Novartis, Celgene, Ortho Dermatologics, Janssen, and Merck; two authors are Sun employees.

Psoriasis: A look back over the past 50 years, and forward to next steps
Imagine a patient suffering with horrible psoriasis for decades having failed “every available treatment.” Imagine him living all that time with “flaking, cracking, painful, itchy skin,” only to develop cirrhosis after exposure to toxic therapies.
Then imagine the experience for that patient when, 2 weeks after initiating treatment with a new interleukin-17 inhibitor, his skin clears completely.
“Two weeks later it’s all gone – it was a moment to behold,” said Joel M. Gelfand, MD, professor of dermatology and epidemiology at the University of Pennsylvania, Philadelphia, who had cared for the man for many years before a psoriasis treatment revolution of sorts took the field of dermatology by storm.
“The progress has been breathtaking – there’s no other way to describe it – and it feels like a miracle every time I see a new patient who has tough disease and I have all these things to offer them,” he continued. “For most patients, I can really help them and make a major difference in their life.”
said Mark Lebwohl, MD, Waldman professor of dermatology and chair of the Kimberly and Eric J. Waldman department of dermatology at the Icahn School of Medicine at Mount Sinai, New York.
Dr. Lebwohl recounted some of his own experiences with psoriasis patients before the advent of treatments – particularly biologics – that have transformed practice.
There was a time when psoriasis patients had little more to turn to than the effective – but “disgusting” – Goeckerman Regimen involving cycles of UVB light exposure and topical crude coal tar application. Initially, the regimen, which was introduced in the 1920s, was used around the clock on an inpatient basis until the skin cleared, Dr. Lebwohl said.
In the 1970s, the immunosuppressive chemotherapy drug methotrexate became the first oral systemic therapy approved for severe psoriasis. For those with disabling disease, it offered some hope for relief, but only about 40% of patients achieved at least a 75% reduction in the Psoriasis Area and Severity Index score (PASI 75), he said, adding that they did so at the expense of the liver and bone marrow. “But it was the only thing we had for severe psoriasis other than light treatments.”
In the 1980s and 1990s, oral retinoids emerged as a treatment for psoriasis, and the immunosuppressive drug cyclosporine used to prevent organ rejection in some transplant patients was found to clear psoriasis in affected transplant recipients. Although they brought relief to some patients with severe, disabling disease, these also came with a high price. “It’s not that effective, and it has lots of side effects ... and causes kidney damage in essentially 100% of patients,” Dr. Lebwohl said of cyclosporine.
“So we had treatments that worked, but because the side effects were sufficiently severe, a lot of patients were not treated,” he said.
Enter the biologics era
The early 2000s brought the first two approvals for psoriasis: alefacept (Amevive), a “modestly effective, but quite safe” immunosuppressive dimeric fusion protein approved in early 2003 for moderate to severe plaque psoriasis, and efalizumab (Raptiva), a recombinant humanized monoclonal antibody approved in October 2003; both were T-cell–targeted therapies. The former was withdrawn from the market voluntarily as newer agents became available, and the latter was withdrawn in 2009 because of a link with development of progressive multifocal leukoencephalopathy.
Tumor necrosis factor (TNF) blockers, which had been used effectively for RA and Crohn’s disease, emerged next, and were highly effective, much safer than the systemic treatments, and gained “very widespread use,” Dr. Lebwohl said.
His colleague Alice B. Gottlieb, MD, PhD, was among the pioneers in the development of TNF blockers for the treatment of psoriasis. Her seminal, investigator-initiated paper on the efficacy and safety of infliximab (Remicade) monotherapy for plaque-type psoriasis published in the Lancet in 2001 helped launch the current era in which many psoriasis patients achieve 100% PASI responses with limited side effects, he said, explaining that subsequent research elucidated the role of IL-12 and -23 – leading to effective treatments like ustekinumab (Stelara), and later IL-17, which is, “in fact, the molecule closest to the pathogenesis of psoriasis.”
“If you block IL-17, you get rid of psoriasis,” he said, noting that there are now several companies with approved antibodies to IL-17. “Taltz [ixekizumab] and Cosentyx [secukinumab] are the leading ones, and Siliq [brodalumab] blocks the receptor for IL-17, so it is very effective.”
Another novel biologic – bimekizumab – is on the horizon. It blocks both IL-17a and IL-17f, and appears highly effective in psoriasis and psoriatic arthritis (PsA). “Biologics were the real start of the [psoriasis treatment] revolution,” he said. “When I started out I would speak at patient meetings and the patients were angry at their physicians; they thought they weren’t aggressive enough, they were very frustrated.”
Dr. Lebwohl described patients he would see at annual National Psoriasis Foundation meetings: “There were patients in wheel chairs, because they couldn’t walk. They would be red and scaly all over ... you could have literally swept up scale like it was snow after one of those meetings.
“You go forward to around 2010 – nobody’s in wheelchairs anymore, everybody has clear skin, and it’s become a party; patients are no longer angry – they are thrilled with the results they are getting from much safer and much more effective drugs,” he said. “So it’s been a pleasure taking care of those patients and going from a very difficult time of treating them, to a time where we’ve done a great job treating them.”
Dr. Lebwohl noted that a “large number of dermatologists have been involved with the development of these drugs and making sure they succeed, and that has also been a pleasure to see.”
Dr. Gottlieb, who Dr. Lebwohl has described as “a superstar” in the fields of dermatology and rheumatology, is one such researcher. In an interview, she looked back on her work and the ways that her work “opened the field,” led to many of her trainees also doing “great work,” and changed the lives of patients.
“It’s nice to feel that I really did change, fundamentally, how psoriasis patients are treated,” said Dr. Gottlieb, who is a clinical professor in the department of dermatology at the Icahn School of Medicine at Mount Sinai. “That obviously feels great.”
She recalled a patient – “a 6-foot-5 biker with bad psoriasis” – who “literally, the minute the door closed, he was crying about how horrible his disease was.”
“And I cleared him ... and then you get big hugs – it just feels extremely good ... giving somebody their life back,” she said.
Dr. Gottlieb has been involved in much of the work in developing biologics for psoriasis, including the ongoing work with bimekizumab for PsA as mentioned by Dr. Lebwohl.
If the phase 2 data with bimekizumab are replicated in the ongoing phase 3 trials now underway at her center, “that can really raise the bar ... so if it’s reproducible, it’s very exciting.”
“It’s exciting to have an IL-23 blocker that, at least in clinical trials, showed inhibition of radiographic progression [in PsA],” she said. “That’s guselkumab those data are already out, and I was involved with that.”
The early work of Dr. Gottlieb and others has also “spread to other diseases,” like hidradenitis suppurativa and atopic dermatitis, she said, noting that numerous studies are underway.
Aside from curing all patients, her ultimate goal is getting to a point where psoriasis has no effect on patients’ quality of life.
“And I see it already,” she said. “It’s happening, and it’s nice to see that it’s happening in children now, too; several of the drugs are approved in kids.”
Alan Menter, MD, chairman of the division of dermatology at Baylor University Medical Center, Dallas, also a prolific researcher – and chair of the guidelines committee that published two new sets of guidelines for psoriasis treatment in 2019 – said that the field of dermatology was “late to the biologic evolution,” as many of the early biologics were first approved for PsA.
“But over the last 10 years, things have changed dramatically,” he said. “After that we suddenly leapt ahead of everybody. ... We now have 11 biologic drugs approved for psoriasis, which is more than any other disease has available.”
It’s been “highly exciting” to see this “evolution and revolution,” he commented, adding that one of the next challenges is to address the comorbidities, such as cardiovascular disease, associated with psoriasis.
“The big question now ... is if you improve skin and you improve joints, can you potentially reduce the risk of coronary artery disease,” he said. “Everybody is looking at that, and to me it’s one of the most exciting things that we’re doing.”
Work is ongoing to look at whether the IL-17s and IL-23s have “other indications outside of the skin and joints,” both within and outside of dermatology.
Like Dr. Gottlieb, Dr. Menter also mentioned the potential for hidradenitis suppurativa, and also for a condition that is rarely discussed or studied: genital psoriasis. Ixekizumab has recently been shown to work in about 75% of patients with genital psoriasis, he noted.
Another important area of research is the identification of biomarkers for predicting response and relapse, he said. For now, biomarker research has disappointed, he added, predicting that it will take at least 3-5 years before biomarkers to help guide treatment are identified.
Indeed, Dr. Gelfand, who also is director of the Psoriasis and Phototherapy Treatment Center, vice chair of clinical research, and medical director of the dermatology clinical studies unit at the University of Pennsylvania, agreed there is a need for research to improve treatment selection.
Advances are being made in genetics – with more than 80 different genes now identified as being related to psoriasis – and in medical informatics – which allow thousands of patients to be followed for years, he said, noting that this could elucidate immunopathological features that can improve treatments, predict and prevent comorbidity, and further improve outcomes.
“We also need care that is more patient centered,” he said, describing the ongoing pragmatic LITE trial of home- or office-based phototherapy for which he is the lead investigator, and other studies that he hopes will expand access to care.
Kenneth Brian Gordon, MD, chair and professor of dermatology at the Medical College of Wisconsin, Milwaukee, whose career started in the basic science immunology arena, added the need for expanding benefit to patients with more-moderate disease. Like Dr. Menter, he identified psoriasis as the area in medicine that has had the greatest degree of advancement, except perhaps for hepatitis C.
He described the process not as a “bench-to-bedside” story, but as a bedside-to-bench, then “back-to-bedside” story.
It was really about taking those early T-cell–targeted biologics and anti-TNF agents from bedside to bench with the realization of the importance of the IL-23 and IL-17 pathways, and that understanding led back to the bedside with the development of the newest agents – and to a “huge difference in patient’s lives.”
“But we’ve gotten so good at treating patients with severe disease ... the question now is how to take care of those with more-moderate disease,” he said, noting that a focus on cost and better delivery systems will be needed for that population.
That research is underway, and the future looks bright – and clear.
“I think with psoriasis therapy and where we’ve come in the last 20 years ... we have a hard time remembering what it was like before we had biologic agents” he said. “Our perspective has changed a lot, and sometimes we forget that.”
In fact, “psoriasis has sort of dragged dermatology into the world of modern clinical trial science, and we can now apply that to all sorts of other diseases,” he said. “The psoriasis trials were the first really well-done large-scale trials in dermatology, and I think that has given dermatology a real leg up in how we do clinical research and how we do evidence-based medicine.”
All of the doctors interviewed for this story have received funds and/or honoraria from, consulted with, are employed with, or served on the advisory boards of manufacturers of biologics. Dr. Gelfand is a copatent holder of resiquimod for treatment of cutaneous T-cell lymphoma and is deputy editor of the Journal of Investigative Dermatology.

It blocks both IL-17a and IL-17f, and appears highly effective in psoriasis and psoriatic arthritis (PsA). “Biologics were the real start of the [psoriasis treatment] revolution,” he said. “When I started out I would speak at patient meetings and the patients were angry at their physicians; they thought they weren’t aggressive enough, they were very frustrated.”
Dr. Lebwohl described patients he would see at annual National Psoriasis Foundation meetings: “There were patients in wheel chairs, because they couldn’t walk. They would be red and scaly all over ... you could have literally swept up scale like it was snow after one of those meetings.
“You go forward to around 2010 – nobody’s in wheelchairs anymore, everybody has clear skin, and it’s become a party; patients are no longer angry – they are thrilled with the results they are getting from much safer and much more effective drugs,” he said. “So it’s been a pleasure taking care of those patients and going from a very difficult time of treating them, to a time where we’ve done a great job treating them.”
Dr. Lebwohl noted that a “large number of dermatologists have been involved with the development of these drugs and making sure they succeed, and that has also been a pleasure to see.”
Dr. Gottlieb, who Dr. Lebwohl has described as “a superstar” in the fields of dermatology and rheumatology, is one such researcher. In an interview, she looked back on her work and the ways that her work “opened the field,” led to many of her trainees also doing “great work,” and changed the lives of patients.
“It’s nice to feel that I really did change, fundamentally, how psoriasis patients are treated,” said Dr. Gottlieb, who is a clinical professor in the department of dermatology at the Icahn School of Medicine at Mount Sinai. “That obviously feels great.”
She recalled a patient – “a 6-foot-5 biker with bad psoriasis” – who “literally, the minute the door closed, he was crying about how horrible his disease was.”
“And I cleared him ... and then you get big hugs – it just feels extremely good ... giving somebody their life back,” she said.
Dr. Gottlieb has been involved in much of the work in developing biologics for psoriasis, including the ongoing work with bimekizumab for PsA as mentioned by Dr. Lebwohl.
If the phase 2 data with bimekizumab are replicated in the ongoing phase 3 trials now underway at her center, “that can really raise the bar ... so if it’s reproducible, it’s very exciting.”
“It’s exciting to have an IL-23 blocker that, at least in clinical trials, showed inhibition of radiographic progression [in PsA],” she said. “That’s guselkumab those data are already out, and I was involved with that.”
The early work of Dr. Gottlieb and others has also “spread to other diseases,” like hidradenitis suppurativa and atopic dermatitis, she said, noting that numerous studies are underway.
Aside from curing all patients, her ultimate goal is getting to a point where psoriasis has no effect on patients’ quality of life.
“And I see it already,” she said. “It’s happening, and it’s nice to see that it’s happening in children now, too; several of the drugs are approved in kids.”
Alan Menter, MD, chairman of the division of dermatology at Baylor University Medical Center, Dallas, also a prolific researcher – and chair of the guidelines committee that published two new sets of guidelines for psoriasis treatment in 2019 – said that the field of dermatology was “late to the biologic evolution,” as many of the early biologics were first approved for PsA.
“But over the last 10 years, things have changed dramatically,” he said. “After that we suddenly leapt ahead of everybody. ... We now have 11 biologic drugs approved for psoriasis, which is more than any other disease has available.”
It’s been “highly exciting” to see this “evolution and revolution,” he commented, adding that one of the next challenges is to address the comorbidities, such as cardiovascular disease, associated with psoriasis.
“The big question now ... is if you improve skin and you improve joints, can you potentially reduce the risk of coronary artery disease,” he said. “Everybody is looking at that, and to me it’s one of the most exciting things that we’re doing.”
Work is ongoing to look at whether the IL-17s and IL-23s have “other indications outside of the skin and joints,” both within and outside of dermatology.
Like Dr. Gottlieb, Dr. Menter also mentioned the potential for hidradenitis suppurativa, and also for a condition that is rarely discussed or studied: genital psoriasis. Ixekizumab has recently been shown to work in about 75% of patients with genital psoriasis, he noted.
Another important area of research is the identification of biomarkers for predicting response and relapse, he said. For now, biomarker research has disappointed, he added, predicting that it will take at least 3-5 years before biomarkers to help guide treatment are identified.
Indeed, Dr. Gelfand, who also is director of the Psoriasis and Phototherapy Treatment Center, vice chair of clinical research, and medical director of the dermatology clinical studies unit at the University of Pennsylvania, agreed there is a need for research to improve treatment selection.
Advances are being made in genetics – with more than 80 different genes now identified as being related to psoriasis – and in medical informatics – which allow thousands of patients to be followed for years, he said, noting that this could elucidate immunopathological features that can improve treatments, predict and prevent comorbidity, and further improve outcomes.
“We also need care that is more patient centered,” he said, describing the ongoing pragmatic LITE trial of home- or office-based phototherapy for which he is the lead investigator, and other studies that he hopes will expand access to care.
Kenneth Brian Gordon, MD, chair and professor of dermatology at the Medical College of Wisconsin, Milwaukee, whose career started in the basic science immunology arena, added the need for expanding benefit to patients with more-moderate disease. Like Dr. Menter, he identified psoriasis as the area in medicine that has had the greatest degree of advancement, except perhaps for hepatitis C.
He described the process not as a “bench-to-bedside” story, but as a bedside-to-bench, then “back-to-bedside” story.
It was really about taking those early T-cell–targeted biologics and anti-TNF agents from bedside to bench with the realization of the importance of the IL-23 and IL-17 pathways, and that understanding led back to the bedside with the development of the newest agents – and to a “huge difference in patient’s lives.”
“But we’ve gotten so good at treating patients with severe disease ... the question now is how to take care of those with more-moderate disease,” he said, noting that a focus on cost and better delivery systems will be needed for that population.
That research is underway, and the future looks bright – and clear.
“I think with psoriasis therapy and where we’ve come in the last 20 years ... we have a hard time remembering what it was like before we had biologic agents” he said. “Our perspective has changed a lot, and sometimes we forget that.”
In fact, “psoriasis has sort of dragged dermatology into the world of modern clinical trial science, and we can now apply that to all sorts of other diseases,” he said. “The psoriasis trials were the first really well-done large-scale trials in dermatology, and I think that has given dermatology a real leg up in how we do clinical research and how we do evidence-based medicine.”
All of the doctors interviewed for this story have received funds and/or honoraria from, consulted with, are employed with, or served on the advisory boards of manufacturers of biologics. Dr. Gelfand is a copatent holder of resiquimod for treatment of cutaneous T-cell lymphoma and is deputy editor of the Journal of Investigative Dermatology.
Registry data reveal temporal relationship between psoriasis symptoms and PsA onset
ATLANTA – Psoriasis type and patient age at presentation among patients with psoriatic arthritis predict the timing of arthritis symptom synchronicity, according to findings from the Psoriatic Arthritis Registry of Turkey International Database.
However, in those who develop arthritis symptoms first, age at onset is not predictive of psoriatic arthritis (PsA) symptom synchronicity, Umut Kalyoncu, MD, reported at the annual meeting of the American College of Rheumatology.
Of 1,631 patients from the registry, 1,251 had psoriasis first, 71 had arthritis first, and 309 had synchronous onset, which was defined as the onset of both psoriasis and arthritis symptoms within a 12-month period. The time from skin disease to PsA was 155.6 months, –67.4 months, and 1.8 months, among the groups, respectively, and the mean age at PsA onset was similar, ranging from about 41 to 42 years in those who developed arthritis first, said Dr. Kalyoncu, of the department of rheumatology at Hacettepe University, Ankara, Turkey.
However, the mean age of PsA onset among those who developed psoriasis first was 29.4 years, compared with 46.3 years in those who developed arthritis first.
“So there is a really big difference between psoriasis beginning age,” he said.
PsA types also differed by onset symptoms: Axial involvement was more common with arthritis-first onset at 38.0%, compared with 28.8% for psoriasis first and 27.8% for synchronous onset). Oligoarthritis occurred more often with arthritis-first onset (45.1% vs. 30.7% and 29.4%, respectively), and polyarthritis occurred less often with arthritis-first onset (33.8% vs. 49.4% and 47.6%, respectively), he said.
Psoriasis type also differed among the groups: Pustular skin involvement was more common in arthritis-first patients (18.3% vs. 11.9% and 16.5% of psoriasis-first and synchronous-onset patients), scalp lesions as the initial lesion were more common in psoriasis-first patients (48.3% vs. 35.2% of arthritis-first patients and 39.8% of synchronous-onset patients), and genital involvement was present more often in arthritis-first patients (12.7% vs. 6.2% and 4.9% of psoriasis-first and synchronous-onset patients).
Early-onset (type 1) psoriasis was more common in psoriasis-first patients (74% vs. 28.1% and 51.8% of arthritis-first and synchronous-onset patients), whereas late-onset (type 2) psoriasis was more common in arthritis-first patients (71.9% vs. 26.0% and 48.2% for psoriasis-first and synchronous-onset patients).
A family history of psoriasis or PsA was more common in psoriasis-first patients (35.6% vs. 26.3% and 28.2% of arthritis-first and synchronous-onset patients), Dr. Kalyoncu said.
Treatment types did not differ between the groups.
Multiple linear regression analysis for the time elapsed from psoriasis to PsA symptom synchronicity, with all other independent variables set to baseline values, showed an overall intercept interval of 66 months, but with nail involvement, family history, or plaque psoriasis, the interval was extended by 28, 24, and 20 months, respectively. However, the presence of pustular psoriasis decreased the intercept interval by 28 months.
A temporal relationship between the onset of skin psoriasis and PsA is a well-known feature of psoriatic disease, with prior studies showing that the majority of cases involve psoriasis-first onset, Dr. Kalyoncu said, adding that heterogeneity in musculoskeletal and skin involvement is also a known feature.
However, little is known about the role of genetics, he noted.
Therefore, he and his colleagues used the Psoriatic Arthritis Registry of Turkey International Database, which was established in 2014 and now also includes data from patients in Canada and Italy, to explore the associations between disease characteristics and the temporal relationship of skin and musculoskeletal disease.
Based on the findings, age at the onset of psoriasis was the main factor that determined PsA symptom synchronicity, he said.
“We know that HLA-Cw6 is important in genetic susceptibility of psoriatic arthritis, but it is important only for early-onset arthritis, not late-onset psoriasis,” Dr. Kalyoncu said. “So our results make an indirect contribution [to the understanding of] these genetic and immunochemical differences between early-onset and late-onset psoriasis, and we need further future studies about this topic.”
Dr. Kalyoncu reported having no relevant disclosures.

REPORTING FROM ACR 2019
In rheumatology, biosimilars are flatlining. Why?
Although biosimilar versions of tumor necrosis factor inhibitors (TNFis) have been available to U.S. rheumatologists and their patients for over 3 years, uptake has thus far been slow.
In an analysis of data from a large commercial payer, the two available biosimilars for infliximab (Remicade) accounted for less than 1% of TNFi prescribing since the first biosimilar to infliximab was approved in 2016.
The study, published in Arthritis & Rheumatology, involved a total of 1.1 million TNFi prescriptions or infusions received by 95,906 patients from 2016 to 2019. Investigators found that uptake of biosimilar infliximab was essentially flat, standing at 0.1% of prescribing in the second quarter of 2017, and topping out at 0.9% in the first quarter of 2019. For branded infliximab, prescribing was also stable, but accounted for about 20% of overall biologic dispensing in each quarter of the period studied.
There are currently two biosimilar medications to the originator infliximab, which is one of five originator biologics available to treat rheumatic diseases in the United States: infliximab-dyyb (Inflectra) and infliximab-abda (Renflexis). The former was approved in 2016 and the latter in 2017, said study author Seoyoung C. Kim, MD, ScD, of the division of pharmacoepidemiology and pharmacoeconomics, Brigham and Women’s Hospital, Boston, and her coauthors.
“Our paper reports a disappointingly low uptake of biosimilar infliximab since the first quarter of 2017 using claims data from a large private health plan. The main and maybe the only reason to consider using a biosimilar is cost saving,” said Dr. Kim in an interview. “Our results suggest that current modest cost savings from infliximab biosimilars in the U.S. are not sufficient to promote their widespread use.”
In the payer database study conducted by Dr. Kim and colleagues, the insurer paid similar mean amounts per patient per quarter for originator and biosimilar infliximab in mid-2017 ($8,322 versus $8,656). By the end of 2018, a gap appeared, with the insurer paying a mean quarterly per-patient sum of $8,111 for biosimilar infliximab compared with $9,535 for the branded biologic.
“The lack of market penetration and very modest price reductions for biosimilars have left policymakers, payers, physicians, and the public frustrated, particularly because sales in Europe continue to rapidly expand and robust cost-savings have materialized,” wrote Jinoos Yazdany, MD, MPH, in an editorial accompanying the study.
Dr. Yazdany, professor and chief of the division of rheumatology at the University of California, San Francisco, noted that increased spending on biologics in the United States – which increased by 50% from 2014 to 2018 – has been driven by rising prices as well as increased uptake of biologic therapies.
At least in part, Europe has been able to reap cost savings where the United States hasn’t because fundamental differences in health care reimbursement can ease sweeping biosimilar adoption, Dr. Yazdany noted. “Countries like Denmark and Sweden, using the negotiating and purchasing power of their single-payer systems have instituted a winner-takes-all bidding system,” with Denmark seeing cost savings of up to two-thirds when bidding was combined with mandatory switching, she said.
The continued market dominance of originator infliximab means that savings from biosimilars have thus far amounted to about $91 million, far short of the $1 billion that the Congressional Budget Office had projected for this date, Dr. Yazdany said.
One problem in the adoption of biosimilars by U.S. rheumatologists may have been uneven marketing and pricing across different types of practice, Colin C. Edgerton, MD, a rheumatologist at Low Country Rheumatology in South Carolina and chair of the American College of Rheumatology’s Committee on Rheumatologic Care, said in an interview.
“Rheumatologists have generally developed comfort with biosimilars, although this is not universal. The core message, that all biologics vary and that this is OK, is getting out. In general, rheumatologists also understand the problem with high drug prices and the threat to patient access,” Dr. Edgerton said. But “the early marketing and pricing focus for biosimilars seemed to be on hospitals and facilities, and this did not work effectively for community rheumatologists, where the majority of care is delivered. We have been pleased to see a manufacturer pivot toward community rheumatology where additional efforts need to be made to bend the curve on biosimilar adoption. It is critical for practices with experience using biosimilars to educate peers, and this is where networks of practicing rheumatologists are important.”
In Dr. Yazdany’s editorial, she cited four structural factors impeding biosimilar uptake and downstream savings.
First, she cites ongoing actions by pharmaceutical companies, which create a “patent thicket” that has the effect of fencing off originator biologics from biosimilars long beyond the original 12-year exclusivity period. Supporting the notion that “patent thickets” are a common strategy, Dr. Yazdany noted that almost half of the patent applications that AbbVie has filed for adalimumab (Humira) have come in after the original exclusivity period expired in 2014. Humira’s price has risen 18% yearly during this period.
The complicated role played by pharmacy benefit managers (PBMs) is another factor in slow adoption, said Dr. Yazdany: When manufacturers offer rebates to PBMs, the price of the originator biologic may be less than its biosimilar. Further, manufacturers may sign multiyear rebate agreements just before a biosimilar launch; PBMs are also sometimes threatened with the withdrawal of rebates if they offer biosimilars, she noted.
Third, prescriber inertia may also be at play, Dr. Yazdany noted, not least because patients often see little difference in out-of-pocket costs when they make the switch to a biosimilar – PBM rebates are not necessarily passed on to patients. Payers may not reimburse a biosimilar, or formularies can be built without them, influencing prescribing, and there’s usually no reimbursement incentive for biosimilar prescribing in the nonpublic sector, she said. To the contrary, infusing a drug with a higher price often means higher reimbursement for the administering clinician, since commercial insurance reimbursement is often calculated as a percent of the charge for the drug.
Further contributing to inertia is the extra time required for patient education and writing a new set of orders – all work that can’t be captured for extra reimbursement. Dr. Edgerton said that rheumatologists can talk with patients about the “nocebo effect” relating to biosimilars. “This is a phenomenon in which patients are thought to experience worsening symptoms associated with negative beliefs about biosimilars. There has been a study in Arthritis Care & Research addressing this concern. The authors found that positive framing of biosimilars led to more participants being willing to switch than negative framing. This suggests that clinicians have an important role in informing patients about biosimilars, and addressing hesitancy.”
Finally, Dr. Yazdany pointed out that for a pharmaceutical company pursuing biosimilar approval, the regulatory pathway itself can provide its own set of complications and confusion. Biosimilars are not exact molecular replicas of the originator biologic, and these differences can change efficacy and immunogenicity, and also affect stability. Hence, a company wishing to market a biosimilar has to show the Food and Drug Administration that safety and efficacy aren’t affected by a switch to biosimilar from an originator biologic. Extrapolation from one indication to another can be made – with scientific justification.
Rheumatologists are mindful of the potential differences between biosimilars and the originator biologic, as evinced in a recent position statement from the American College of Rheumatology. The position statement advises that “extrapolation should be pursued with caution,” and asks for clear labeling when biosimilars have been designated “interchangeable” with their biosimilar. Interchangeability can clear the way for pharmacy substitution of a prescribed biologic, though Dr. Yazdany noted that 40 states have passed legislation requiring prescriber notification.
The FDA is currently using postmarketing pharmacovigilance to monitor biosimilar performance in the real world, and a recent systematic review “should provide some reassurance,” wrote Dr. Yazdany, citing the study, which looked at 14,000 patients who had a total of 14 disease indications for biosimilar use. The 90-article review largely found no differences in safety, efficacy, or immunogenicity between originators and their biosimilars. Dr. Yazdany recommended greater openness to incorporating the European experience in the FDA’s ongoing reassessment.
A further way forward can come through tackling the patent thicket with the proposed bipartisan Biologic Patent Transparency Act, which would require publication of biologic patents in a one-stop publicly searchable database. Going further with legislation to address anticompetitive activity by pharmaceutical companies could shorten the runway to biosimilar launching considerably, she noted.
The complicated landscape of PBMs and rebates affects many sectors of health care, and new policy efforts are needed here as well, she said. Reimbursement strategies – and much-needed continuing medical education – can both ease prescriber unfamiliarity with biosimilars and provide incentives for their use, she concluded.
Dr. Kim concurred that change is needed before the United States is likely to reap significant economic benefit from biosimilars. “The uptake of biosimilars and their impact on overall health care cost needs to be reevaluated when we have more biosimilars available in the next 3-4 years. However, for now, it appears that substantial savings achieved in some European countries – for example, Denmark – may not be possible without systemic reform of the U.S. pharmaceutical market,” she said.
Dr. Yazdany is supported by the Alice Betts Endowed Chair in Arthritis Research, the Russel/Engleman Research Center at the University of California, San Francisco, and the National Institutes of Health. She has received independent research grants from Pfizer and Genentech and research consulting fees from Eli Lilly and AstraZeneca.
Dr. Kim’s study was supported by the division of pharmacoepidemiology and pharmacoeconomics, department of medicine, Brigham and Women’s Hospital, and Arnold Ventures. Dr. Kim has received research grants to Brigham and Women’s Hospital from Pfizer, AbbVie, Bristol-Myers Squibb, and Roche.

The main and maybe the only reason to consider using a biosimilar is cost saving,” said Dr. Kim in an interview. “Our results suggest that current modest cost savings from infliximab biosimilars in the U.S. are not sufficient to promote their widespread use.”
In the payer database study conducted by Dr. Kim and colleagues, the insurer paid similar mean amounts per patient per quarter for originator and biosimilar infliximab in mid-2017 ($8,322 versus $8,656). By the end of 2018, a gap appeared, with the insurer paying a mean quarterly per-patient sum of $8,111 for biosimilar infliximab compared with $9,535 for the branded biologic.
“The lack of market penetration and very modest price reductions for biosimilars have left policymakers, payers, physicians, and the public frustrated, particularly because sales in Europe continue to rapidly expand and robust cost-savings have materialized,” wrote Jinoos Yazdany, MD, MPH, in an editorial accompanying the study.
Dr. Yazdany, professor and chief of the division of rheumatology at the University of California, San Francisco, noted that increased spending on biologics in the United States – which increased by 50% from 2014 to 2018 – has been driven by rising prices as well as increased uptake of biologic therapies.
At least in part, Europe has been able to reap cost savings where the United States hasn’t because fundamental differences in health care reimbursement can ease sweeping biosimilar adoption, Dr. Yazdany noted. “Countries like Denmark and Sweden, using the negotiating and purchasing power of their single-payer systems have instituted a winner-takes-all bidding system,” with Denmark seeing cost savings of up to two-thirds when bidding was combined with mandatory switching, she said.
The continued market dominance of originator infliximab means that savings from biosimilars have thus far amounted to about $91 million, far short of the $1 billion that the Congressional Budget Office had projected for this date, Dr. Yazdany said.
One problem in the adoption of biosimilars by U.S. rheumatologists may have been uneven marketing and pricing across different types of practice, Colin C. Edgerton, MD, a rheumatologist at Low Country Rheumatology in South Carolina and chair of the American College of Rheumatology’s Committee on Rheumatologic Care, said in an interview.
“Rheumatologists have generally developed comfort with biosimilars, although this is not universal. The core message, that all biologics vary and that this is OK, is getting out. In general, rheumatologists also understand the problem with high drug prices and the threat to patient access,” Dr. Edgerton said. But “the early marketing and pricing focus for biosimilars seemed to be on hospitals and facilities, and this did not work effectively for community rheumatologists, where the majority of care is delivered. We have been pleased to see a manufacturer pivot toward community rheumatology where additional efforts need to be made to bend the curve on biosimilar adoption. It is critical for practices with experience using biosimilars to educate peers, and this is where networks of practicing rheumatologists are important.”
In Dr. Yazdany’s editorial, she cited four structural factors impeding biosimilar uptake and downstream savings.
First, she cites ongoing actions by pharmaceutical companies, which create a “patent thicket” that has the effect of fencing off originator biologics from biosimilars long beyond the original 12-year exclusivity period. Supporting the notion that “patent thickets” are a common strategy, Dr. Yazdany noted that almost half of the patent applications that AbbVie has filed for adalimumab (Humira) have come in after the original exclusivity period expired in 2014. Humira’s price has risen 18% yearly during this period.
The complicated role played by pharmacy benefit managers (PBMs) is another factor in slow adoption, said Dr. Yazdany: When manufacturers offer rebates to PBMs, the price of the originator biologic may be less than its biosimilar. Further, manufacturers may sign multiyear rebate agreements just before a biosimilar launch; PBMs are also sometimes threatened with the withdrawal of rebates if they offer biosimilars, she noted.
Third, prescriber inertia may also be at play, Dr. Yazdany noted, not least because patients often see little difference in out-of-pocket costs when they make the switch to a biosimilar – PBM rebates are not necessarily passed on to patients. Payers may not reimburse a biosimilar, or formularies can be built without them, influencing prescribing, and there’s usually no reimbursement incentive for biosimilar prescribing in the nonpublic sector, she said. To the contrary, infusing a drug with a higher price often means higher reimbursement for the administering clinician, since commercial insurance reimbursement is often calculated as a percent of the charge for the drug.
Further contributing to inertia is the extra time required for patient education and writing a new set of orders – all work that can’t be captured for extra reimbursement. Dr. Edgerton said that rheumatologists can talk with patients about the “nocebo effect” relating to biosimilars. “This is a phenomenon in which patients are thought to experience worsening symptoms associated with negative beliefs about biosimilars. There has been a study in Arthritis Care & Research addressing this concern. The authors found that positive framing of biosimilars led to more participants being willing to switch than negative framing. This suggests that clinicians have an important role in informing patients about biosimilars, and addressing hesitancy.”
Finally, Dr. Yazdany pointed out that for a pharmaceutical company pursuing biosimilar approval, the regulatory pathway itself can provide its own set of complications and confusion. Biosimilars are not exact molecular replicas of the originator biologic, and these differences can change efficacy and immunogenicity, and also affect stability. Hence, a company wishing to market a biosimilar has to show the Food and Drug Administration that safety and efficacy aren’t affected by a switch to biosimilar from an originator biologic. Extrapolation from one indication to another can be made – with scientific justification.
Rheumatologists are mindful of the potential differences between biosimilars and the originator biologic, as evinced in a recent position statement from the American College of Rheumatology. The position statement advises that “extrapolation should be pursued with caution,” and asks for clear labeling when biosimilars have been designated “interchangeable” with their biosimilar. Interchangeability can clear the way for pharmacy substitution of a prescribed biologic, though Dr. Yazdany noted that 40 states have passed legislation requiring prescriber notification.
The FDA is currently using postmarketing pharmacovigilance to monitor biosimilar performance in the real world, and a recent systematic review “should provide some reassurance,” wrote Dr. Yazdany, citing the study, which looked at 14,000 patients who had a total of 14 disease indications for biosimilar use. The 90-article review largely found no differences in safety, efficacy, or immunogenicity between originators and their biosimilars. Dr. Yazdany recommended greater openness to incorporating the European experience in the FDA’s ongoing reassessment.
A further way forward can come through tackling the patent thicket with the proposed bipartisan Biologic Patent Transparency Act, which would require publication of biologic patents in a one-stop publicly searchable database. Going further with legislation to address anticompetitive activity by pharmaceutical companies could shorten the runway to biosimilar launching considerably, she noted.
The complicated landscape of PBMs and rebates affects many sectors of health care, and new policy efforts are needed here as well, she said. Reimbursement strategies – and much-needed continuing medical education – can both ease prescriber unfamiliarity with biosimilars and provide incentives for their use, she concluded.
Dr. Kim concurred that change is needed before the United States is likely to reap significant economic benefit from biosimilars. “The uptake of biosimilars and their impact on overall health care cost needs to be reevaluated when we have more biosimilars available in the next 3-4 years. However, for now, it appears that substantial savings achieved in some European countries – for example, Denmark – may not be possible without systemic reform of the U.S. pharmaceutical market,” she said.

Although biosimilar versions of tumor necrosis factor inhibitors (TNFis) have been available to U.S. rheumatologists and their patients for over 3 years, uptake has thus far been slow.
In an analysis of data from a large commercial payer, the two available biosimilars for infliximab (Remicade) accounted for less than 1% of TNFi prescribing since the first biosimilar to infliximab was approved in 2016.
The study, published in Arthritis & Rheumatology, involved a total of 1.1 million TNFi prescriptions or infusions received by 95,906 patients from 2016 to 2019. Investigators found that uptake of biosimilar infliximab was essentially flat, standing at 0.1% of prescribing in the second quarter of 2017, and topping out at 0.9% in the first quarter of 2019. For branded infliximab, prescribing was also stable, but accounted for about 20% of overall biologic dispensing in each quarter of the period studied.
There are currently two biosimilar medications to the originator infliximab, which is one of five originator biologics available to treat rheumatic diseases in the United States: infliximab-dyyb (Inflectra) and infliximab-abda (Renflexis). The former was approved in 2016 and the latter in 2017, said study author Seoyoung C. Kim, MD, ScD, of the division of pharmacoepidemiology and pharmacoeconomics, Brigham and Women’s Hospital, Boston, and her coauthors.

Apremilast more likely to succeed with moderate psoriatic arthritis activity
new research suggests.
A paper published in Arthritis Care & Research presents a pooled analysis of the PALACE 1-3 studies that included a total of 1,493 patients with active psoriatic arthritis whose disease had resisted treatment with tumor necrosis factor inhibitors or conventional disease-modifying antirheumatic drugs. Participants were randomized either to the oral phosphodiesterase 4 inhibitor apremilast (Otezla) 30 mg twice daily, 20 mg twice daily, or placebo for 24 weeks, after which all patients on placebo were rerandomized to one of the two apremilast doses until 52 weeks.
The analysis focused on 494 patients who were randomized to apremilast 30 mg twice daily at baseline.
At week 16, 40% patients with low disease activity at baseline had achieved remission on their clinical Disease Activity Index for Psoriatic Arthritis (cDAPSA) score, compared with 7% of patients with moderate disease activity and 2.1% of patients with high disease activity. The cDAPSA score is calculated as a composite score including swollen and tender joint counts, patient’s assessment of pain, and patient’s global assessment of disease activity, with possible scores from 0 to 154. Based on patients’ cDAPSA score, the researchers defined remission as a score of 4 or less, low disease activity as more than 4 and up to 13, moderate disease activity as more than 13 and up to 27, and high disease activity as greater than 27.
Among patients with moderate disease activity, 29.8% achieved low disease activity by week 16; among patients with high disease activity at baseline, 11.5% achieved low disease activity, and 38.1% achieved moderate disease activity.
The study found that patients who had moderate disease activity at baseline and achieved either low disease activity or remission by week 16 had a 58.9%-88.5% probability of remaining at those treatment targets by week 52. Patients with high disease activity at baseline who achieved low disease activity or remission by week 16 had a 64.3%-77.4% probability of achieving treatment targets by week 52.
Overall, nearly twice as many patients who had moderate disease activity at baseline achieved their treatment targets when compared with those who began with high disease activity (46.9% vs. 24.9%).
Any patient who achieved at least a 30% improvement in cDAPSA score by week 16 had a 63% probability of achieving treatment targets by week 52.
First author Philip J. Mease, MD, from the Swedish Medical Center and the University of Washington, Seattle, and coauthors noted that the absence of treatment response by week 16 should point to the need for a treatment adjustment. “Taken together, these findings provide a framework of reference for the selection and monitoring of patients with the highest likelihood of achieving optimal treatment responses with apremilast in clinical practice,” they wrote.
The authors also commented that their study provided support for the use of clinical Disease Activity Index for Psoriatic Arthritis score to monitor patients treated with apremilast.
The study was sponsored by Celgene. Three authors were employees of Celgene at the time of the study, and nine authors declared a range of consultancies, grants, research, and other support from the pharmaceutical sector, including from Celgene.

Bimekizumab elevates psoriasis therapy
MADRID – Renowned dermatologic clinical trialist Kim A. Papp, MD, PhD, is known to pick his words carefully, and the word he uses to describe the quality of life improvement documented in psoriasis patients treated with the novel investigational humanized monoclonal antibody bimekizumab is “phenomenal.”
Dr. Papp was lead investigator in the previously reported phase 2b multicenter BE ABLE 1 trial, in which 250 patients with moderate to severe chronic plaque psoriasis were randomized double-blind to various doses of bimekizumab or placebo every 4 weeks for 12 weeks (J Am Acad Dermatol. 2018 Aug;79[2]:277-86.e10. doi: 10.1016/j.jaad.2018.03.037). He was also lead investigator in the 48-week phase 2b BE ABLE 2 extension study. He presented the 60-week quality-of-life BE ABLE 2 results for the first time at the annual congress of the European Academy of Dermatology and Venereology.
“Small numbers, but the results are nonetheless very compelling,” said Dr. Papp, president and founder of Probity Medical Research in Waterloo, Ont.
Bimekizumab is unique in that it selectively neutralizes both interleukin-17A and -17F, two closely related proinflammatory cytokines which, when upregulated, synergize with other proinflammatory cytokines to drive psoriasis and other immune-mediated inflammatory diseases. In contrast, secukinumab (Cosentyx) and ixekizumab (Taltz) specifically inhibit only IL-17A, and brodalumab (Siliq) targets the IL-17 receptor A. The bimekizumab clinical trials program – a work in progress – aims to demonstrate that dual neutralization of IL-17A and -17F provides a more complete therapeutic approach in psoriasis, with greater efficacy and fewer safety concerns than with current biologics, the dermatologist explained.
In BE ABLE 1, the primary endpoint of at least a 90% reduction in Psoriasis Area and Severity Index (PASI90) response was achieved at week 12 in 46%-79% of patients randomized to bimekizumab in dose-dependent fashion. Those PASI90 responses were maintained with additional treatment out to week 60 in BE ABLE 2 in 80%-100% of patients.
Dr. Papp’s focus at EADV 2019 was on the quality-of-life improvement achieved in bimekizumab-treated patients, a benefit not captured by PASI scores. For this purpose, he and coinvestigators turned to the Dermatology Life Quality Index (DLQI), measured in structured fashion every 4 weeks out to week 60.
“We often forget that even though we’re looking at the patient from the outside, what’s really important is how well they respond to our treatments internally. The DLQI is not a perfect tool, but it’s the best tool we have available. It gives us a fairly good survey of the various domains that affect patients’ day-to-day living,” he said.
In BE ABLE 1, the proportion of week-12 PASI90 responders achieving a DLQI of 0 or 1 – indicative of essentially no disease impact on quality of life – increased rapidly up until week 8. At week 12, 70%-100% of the PASI90 responders in the various treatment arms had a DLQI of 0 or 1. This quality-of-life improvement, like the PASI90 response, proved durable: When the week-12 PASI90 responders were assessed at week 60 in BE ABLE 2, 76%-93% of them had a DLQI of 0 or 1.
The improvements in quality of life correlated with clinical response. BE ABLE enrollees had an average PASI score of 19 at baseline. Overall, 79% of those with an absolute PASI score of 0 at week 12 had a DLQI of 0 or 1 at that time, as did 95% of those with a PASI of 0 at week 60. A PASI of 1 was associated with a 77% likelihood of a DLQI of 0 or 1 at week 12 and an 82% rate at week 60. In contrast, patients with an absolute PASI of 2-4 at week 12 had a 46% rate of DLQI 0/1, and those with a PASI 2-4 at week 60 had a 50% chance of having a DLQI of 0/1.
Phase 3 clinical trials of bimekizumab totaling several thousand psoriasis patients are ongoing.

MADRID – Renowned dermatologic clinical trialist Kim A. Papp, MD, PhD, is known to pick his words carefully, and the word he uses to describe the quality of life improvement documented in psoriasis patients treated with the novel investigational humanized monoclonal antibody bimekizumab is “phenomenal.”
Dr. Papp was lead investigator in the previously reported phase 2b multicenter BE ABLE 1 trial, in which 250 patients with moderate to severe chronic plaque psoriasis were randomized double-blind to various doses of bimekizumab or placebo every 4 weeks for 12 weeks (J Am Acad Dermatol. 2018 Aug;79[2]:277-86.e10. doi: 10.1016/j.jaad.2018.03.037). He was also lead investigator in the 48-week phase 2b BE ABLE 2 extension study. He presented the 60-week quality-of-life BE ABLE 2 results for the first time at the annual congress of the European Academy of Dermatology and Venereology.
“Small numbers, but the results are nonetheless very compelling,” said Dr. Papp, president and founder of Probity Medical Research in Waterloo, Ont.
Bimekizumab is unique in that it selectively neutralizes both interleukin-17A and -17F, two closely related proinflammatory cytokines which, when upregulated, synergize with other proinflammatory cytokines to drive psoriasis and other immune-mediated inflammatory diseases. In contrast, secukinumab (Cosentyx) and ixekizumab (Taltz) specifically inhibit only IL-17A, and brodalumab (Siliq) targets the IL-17 receptor A. The bimekizumab clinical trials program – a work in progress – aims to demonstrate that dual neutralization of IL-17A and -17F provides a more complete therapeutic approach in psoriasis, with greater efficacy and fewer safety concerns than with current biologics, the dermatologist explained.
In BE ABLE 1, the primary endpoint of at least a 90% reduction in Psoriasis Area and Severity Index (PASI90) response was achieved at week 12 in 46%-79% of patients randomized to bimekizumab in dose-dependent fashion. Those PASI90 responses were maintained with additional treatment out to week 60 in BE ABLE 2 in 80%-100% of patients.
Dr. Papp’s focus at EADV 2019 was on the quality-of-life improvement achieved in bimekizumab-treated patients, a benefit not captured by PASI scores. For this purpose, he and coinvestigators turned to the Dermatology Life Quality Index (DLQI), measured in structured fashion every 4 weeks out to week 60.
“We often forget that even though we’re looking at the patient from the outside, what’s really important is how well they respond to our treatments internally. The DLQI is not a perfect tool, but it’s the best tool we have available. It gives us a fairly good survey of the various domains that affect patients’ day-to-day living,” he said.
In BE ABLE 1, the proportion of week-12 PASI90 responders achieving a DLQI of 0 or 1 – indicative of essentially no disease impact on quality of life – increased rapidly up until week 8. At week 12, 70%-100% of the PASI90 responders in the various treatment arms had a DLQI of 0 or 1. This quality-of-life improvement, like the PASI90 response, proved durable: When the week-12 PASI90 responders were assessed at week 60 in BE ABLE 2, 76%-93% of them had a DLQI of 0 or 1.
The improvements in quality of life correlated with clinical response. BE ABLE enrollees had an average PASI score of 19 at baseline. Overall, 79% of those with an absolute PASI score of 0 at week 12 had a DLQI of 0 or 1 at that time, as did 95% of those with a PASI of 0 at week 60. A PASI of 1 was associated with a 77% likelihood of a DLQI of 0 or 1 at week 12 and an 82% rate at week 60. In contrast, patients with an absolute PASI of 2-4 at week 12 had a 46% rate of DLQI 0/1, and those with a PASI 2-4 at week 60 had a 50% chance of having a DLQI of 0/1.
Phase 3 clinical trials of bimekizumab totaling several thousand psoriasis patients are ongoing.

REPORTING FROM THE EADV CONGRESS
Meta-analysis provides safety data on IL-17, IL-23 inhibitors
according to the results of a meta-analysis of 44 studies.
While associated with more adverse events than with placebo, IL-17 and IL-23 inhibitors are “generally well-tolerated and considered safe,” but the extent of adverse events and the existence of a possible drug class effect “have not been fully investigated,” wrote Nikolai D. Loft, MD, of the department of dermatology and allergy at Herlev and Gentofte Hospital in Hellerup, Denmark, and colleagues.
In a study published in the Journal of the European Academy of Dermatology and Venereology, the researchers identified phase 3 studies with data on adverse event reports in patients with psoriasis and psoriatic arthritis who were treated with either IL-17 inhibitors (brodalumab, ixekizumab, or secukinumab) or IL-23 inhibitors (guselkumab, risankizumab, or tildrakizumab).
Overall, across all treatments, the proportion of patients with reports of any adverse events ranged from 0.49 to 0.57 in short-term studies (12-16 weeks) and from 0.83 to 0.93 with long-term treatment (52 weeks). In a pooled analysis, the proportion of patients with any adverse events was 0.57, 0.52, 0.72, and 0.81, at 12, 16, 24, and 52 weeks, respectively.
The most common adverse events across all treatments were infections, nasopharyngitis, and headaches. Among those on ixekizumab, injection-site reactions was one of the most common adverse events reported, in nearly 16% of patients after 52 weeks of treatment, the authors noted.
Fewer adverse events were reported in patients on IL-23 inhibitors, compared with those on IL-17 inhibitors. The proportion of patients reporting serious adverse events was “low,” the researchers wrote. Patients on tildrakizumab had the lowest proportion of any adverse events overall, based on short-term data over 12-16 weeks.
No significant differences emerged in reported adverse events across IL-17 inhibitors after 52 weeks.
Other findings included a higher prevalence of Candida infections among those treated with IL-17 inhibitors after 12-16 weeks and 24 weeks, compared with those on placebo, but the infections, described as mild to moderate, did not result in drug discontinuation, the authors noted. The potential risk of inflammatory bowel disease (IBD) associated with IL-17 inhibitors has been raised as a concern, but in their analysis, “IBD was very rare and after 12 weeks no difference between active treatments and placebo was seen.”
The study findings were limited by several factors, including incomplete data for interdrug comparison, varying time points for safety measures, differences in dosing in clinical trials than the approved dosing, and lack of longer-term follow-up data for most of the treatments, the researchers noted. However, the analysis was strengthened by the inclusion of phase 3 studies with both short-and long-term data, and “overall, IL-17 and IL-23 inhibitors appear to be well-tolerated with good safety profiles.”
Dr. Loft disclosed serving as an honorary speaker for Eli Lilly; other coauthors disclosed relationships with multiple companies; two authors reported no conflicts of interest. There were no funding sources for the study listed.

Ultrasound improves specificity of psoriatic arthritis referrals
The use of ultrasound in screening for psoriatic arthritis in patients with psoriasis could reduce the number of unnecessary referrals to rheumatologists, according to a research letter published in the British Journal of Dermatology.
Up to one-third of patients with psoriasis have underlying psoriatic arthritis (PsA), but half of all patients with psoriasis experience nonspecific musculoskeletal complaints.
“Different screening tools have been developed for the dermatology practice to distinguish patients with a higher likelihood of having PsA; however, the low specificities of these tools limit their use in clinical practice,” wrote Dilek Solmaz, MD, and colleagues at the University of Ottawa.
In this prospective study, 51 patients with psoriasis were screened for referral to a rheumatologist using the Early Arthritis for Psoriatic Patients and Psoriasis Epidemiology Screening Tool questionnaires. They also underwent a limited ultrasound scanning of wrists, hands, feet, and the most painful joint, which was reviewed by experienced rheumatologists.
A dermatologist was asked to make a decision on referral based on the questionnaire data alone, then invited to revisit that decision after viewing the ultrasound results. When basing their decision on the questionnaires only, the dermatologist decided to refer 92% of patients to a rheumatologist. Of these patients, 40% were subsequently diagnosed with PsA, which represented a sensitivity of 95% but specificity of just 9%.
After reviewing the ultrasound data, the dermatologist revised their recommendations and only referred 43% of patients. Of these, 68% were later diagnosed with psoriatic arthritis. Among the patients who were not referred after the ultrasound review, five were diagnosed with PsA, but two had isolated axial involvement with no peripheral joint disease. Excluding these two cases, the sensitivity decreased to 88% but specificity increased to 77%.
“Screening tools in psoriasis that have high sensitivities usually have low specificities, which means a higher number of patients to be referred to rheumatology than needed,” the authors wrote. “Our study demonstrated that a musculoskeletal [ultrasound] based on a predefined protocol improves the referrals made to rheumatology.”
The authors did note that the ultrasounds were reviewed by experienced rheumatologists, so the results might not be generalizable to less-experienced sonographers without experience in musculoskeletal disorders.
The study was funded by AbbVie. One author declared receiving funding for a fellowship from UCB. Two authors declared honoraria and advisory consultancies with the pharmaceutical sector, including AbbVie.
