Psoriatic Arthritis

Nearly a quarter of adults in the United States have been diagnosed with various forms of arthritis, new federal estimates report. The disorders limit the activities of 43.9% of them. Researchers also report that adults with poorer mental or physical health and those who are more disadvantaged socially are most vulnerable to arthritis.

“There is a substantial unmet need for existing, evidence-based, arthritis-appropriate interventions for people with arthritis to minimize activity limitations,” study coauthor and Centers for Disease Control and Prevention epidemiologist Kristina Theis, PhD, MPH, told this news organization. “Our findings show that interventions addressing self-management, education, physical activity, workplace accommodations, and mental health, among other areas, are all indicated for people with arthritis.”

The CDC report was published Oct. 8 in Morbidity and Mortality Weekly Report. Researchers estimated the number of arthritis cases on the basis of in-person interviews conducted with tens of thousands of U.S. adults as part of the National Health Interview Survey during 2016-2018. In the report, the researchers considered arthritis to include general arthritis, rheumatoid arthritis, gout, lupus, and fibromyalgia.
 

Activity limitations rose faster than predicted

According to the report, an estimated 58.5 million U.S. adults (23.7%; 21.5% age-standardized) told interviewers that they had been diagnosed with arthritis conditions. Of those, 25.7 million (43.9%; 40.8% age-standardized) had arthritis-attributable activity limitations (AAALs), which represents 10.4% of all adults.

The number of adults who reported having arthritis rose by 4.1 million from previous estimates for the years 2013-2015, a number that’s on pace with predictions. The number in the AAAL category rose by 2 million, a jump that’s higher than what had been predicted.

“The aging of the population is one factor in the increasing number of people with arthritis, even though arthritis is not an inevitable part of aging,” Dr. Theis said. “Individual factors, such as body mass index or other health conditions, and societal factors, such as educational and economic opportunities, likely play a role.”

Arthritis was especially common among those aged ≥ 65 years (50.4%), those who were unable to work or were disabled (52.3%), and those who self-reported fair/poor health (51.2%) or joint symptoms in the past 30 days (52.2%). The rate of arthritis was also high among those whose activities of daily living (ADL) were limited (54.8%) and those whose instrumental activities of daily living (IADL) were limited (55.9%).

The researchers report that the percentage of AAAL was also high among the following groups: “adults with joint symptoms in the past 30 days (51.6%), adults who were unable to work or disabled (54.7%), adults of other/multiple races (54.5%) or non-Hispanic American Indian or Alaska Natives (60.7%), adults with low income (53.3%) or poor/near poor income-to-poverty ratios (63.3%), or with moderate psychological distress (59.5%). AAAL was reported by a high proportion of adults with arthritis who had an ADL disability (82.6%), IADL disability (80.4%), serious psychological distress (76.3%), or fair/poor self-rated health (72.6%).”

The researchers found that among all adults with arthritis, the percentage of adults with arthritis was high among women (59.3%), those with obesity or overweight (74.2%), and those who weren’t sufficiently active (58%).

Comments on latest findings

Michael LaValley, PhD, biostatistician at the Boston University School of Public Health, who has studied arthritis statistics, told this news organization that the findings “fall right in line with the trends that have been observed in arthritis over the past 20 years. The prevalence is increasing, which certainly seems to be influenced by the aging population in the U.S.”

As for specific conditions, he said the rate of osteoarthritis may be influenced by older Americans and by those with obesity and sedentary behavior. “There is also some thinking that there may be environmental factors increasing the risk for some types of arthritis, but nothing conclusive. There also may be more clinical attention paid to arthritic conditions, leading to more people being diagnosed or even just suspecting that they have arthritis.”

It’s difficult to disentangle connections between arthritis and risk factors such as poverty, he said. “There almost certainly are occupational exposures that put people at risk of osteoarthritis – having to kneel, stoop, and lift heavy things – or other musculoskeletal conditions like lower back pain. These exposures are most likely in jobs that would predominantly go to people with few other options because of lower levels of income and education. People in these jobs would also be more likely to have financial stresses that lead to increased psychological distress and less time to take care of their health.”

Also, he said, “There is probably some reverse causation with the occupational results, self-related health, and psychological distress. These could all be affected by a person’s arthritis. Having arthritis may interfere with getting a better-paying job, and arthritis could certainly reduce someone’s self-reported health and induce psychological distress.”

The authors and LaValley have disclosed no relevant financial relationships.

Patients who are being treated with Janus kinase (JAK) inhibitors overall show a high immune response rate to COVID-19 vaccination, one that matches the rates seen in patients on other immunosuppressants, a new study has found.

The patients taking a JAK inhibitor who are most at risk of a diminished response may be those on upadacitinib (Rinvoq) and anyone 65 years or older, wrote Raphaèle Seror, MD, PhD, of Paris-Saclay (France) University and coauthors. The study was published in The Lancet Rheumatology.

To gauge the effectiveness of COVID-19 vaccines in this subset of immunosuppressed patients, the researchers analyzed 113 participants in the MAJIK-SFR Registry, a multicenter study of French patients with rheumatoid or psoriatic arthritis. The participants were treated at 13 centers throughout France; their mean age was 61.8 years (standard deviation, 12.5), and 72% were female. A total of 56 were taking baricitinib (Olumiant), 30 were taking tofacitinib (Xeljanz), and 27 were taking upadacitinib.

Serologic assessment was performed an average of 8.7 weeks (SD, 5.2) after the last dose of vaccine. The overall response rate – defined as the proportion of patients with detectable anti-spike antibodies per manufacturer’s cutoff values – was 88% (100 of 113). The nonresponse rate was higher with upadacitinib (7 of 27 patients, 26%) than with baricitinib (5 of 56, 9%) or tofacitinib (1 of 30, 3%). The only nonresponders who were not age 65 or older were four of the seven who received upadacitinib. The interval between the last vaccine dose and serologic assessment was somewhat longer in nonresponders (11.3 weeks) than in responders (8.3 weeks).

Earlier this year, the American College of Rheumatology recommended withholding JAK inhibitors for 1 week after each vaccine dose because of “concern related to the effects of this medication class on interferon signaling that may result in a diminished vaccine response Only two patients in the study had treatment with JAK inhibitors stopped before or after vaccination.

Questions about antibody levels remain difficult to answer

“This study does further confirm a big point,” said Alfred Kim, MD, PhD, of Washington University, St. Louis, in an interview. “Most people on any sort of immunosuppression, with rare exceptions, can mount responses to COVID-19 vaccination.”

“What level of response is going to be sufficient, of course, is not clear,” he added. “Even though most people generate responses, at the population level those responses seem lower than those in nonimmunosuppressed people. Particularly for those on upadacitinib, which is lower than patients on the other JAK inhibitors. Is that problematic? We don’t know yet.”

Dr. Kim, who was part of a separate, earlier study that assessed vaccine response in patients with chronic inflammatory disease who were being treated with immunosuppressive medications, noted that many of the questions patients are asking about their antibody levels cannot yet be answered.

“It’s kind of the Wild West of serologic testing out there right now,” he said. “Even though we’re recommending that people still don’t check their antibody levels because their results are largely inactionable, everyone is still getting them anyway. But each of these tests are slightly different, and the results and the interpretation are further clouded because of those slight performance differences between each platform.”

Dr. Kim highlighted the number of different tests as one of this study’s notable limitations: 11 different assays were used to determine patients’ immune responses. “The authors made the argument that these tests are FDA approved, and that’s true, but that doesn’t necessarily mean much. Approval does translate to technical reliability but not to comparisons between the tests.”

As for next steps, both the authors and Dr. Kim recognized the need for a prospective trial. “To do a vaccine effectiveness–type study and show clinical protection against either infection or hospitalization – those are going to take a while, simply because of the nature of how many people you need for each of these studies,” he said. “Time will tell whether or not the data that are being presented here will translate literally into protective outcomes downstream.”

The MAJIK Registry is supported by the French Rheumatology Society. The authors acknowledged numerous potential conflicts of interest, including receiving consulting fees, research support, and honoraria from various pharmaceutical companies.

The Food and Drug Administration approved a supplement to the biologics license application of the adalimumab biosimilar drug Cyltezo (adalimumab-adbm) that makes it the first interchangeable biosimilar with Humira (adalimumab), the original branded version of the drug, its manufacturer Boehringer Ingelheim announced Oct. 15.

The FDA originally approved Cyltezo in 2017 for the treatment of multiple chronic inflammatory diseases, including seven of Humira’s nine indications for adults and pediatric patients: rheumatoid arthritis, polyarticular juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn’s disease, ulcerative colitis, and plaque psoriasis.

The interchangeability designation means that Cyltezo was tested in an additional clinical trial in which patients were successfully switched back and forth multiple times from Humira to Cyltezo and allows pharmacists to autosubstitute Humira with Cyltezo. In these cases, individual state laws control how and whether physicians will be notified of this switch.

Cyltezo is just the second biosimilar to be designated as interchangeable with its originator biologic product. The first approval, announced July 28, was for the interchangeability of Semglee (insulin glargine-yfgn) with the originator Lantus.

The agency based its decision on positive data from the VOLTAIRE-X study of 238 patients with moderate to severe chronic plaque psoriasis in which Cyltezo had no meaningful clinical differences from Humira in pharmacokinetics, efficacy, immunogenicity, and safety between the switching and continuous treatment groups.

Cyltezo will not be commercially available in the United States until July 1, 2023, according to Boehringer Ingelheim.

A new study has found that patients with psoriasis who were treated with biologics were more likely to develop psoriatic arthritis (PsA) than those treated with phototherapy, oral therapy, or no therapy at all, although the authors cautioned readers to consider potential biases when reviewing their findings.

“We do not suggest that these results should be interpreted causally; in other words, biologics likely do not cause PsA,” Elana Meer of the University of Pennsylvania, Philadelphia, and coauthors wrote. The study was published in Annals of the Rheumatic Diseases.

Three studies in dermatology clinic-based populations published this past summer – one from Italy, one from Argentina, and one from Israel – suggested that biologics can decrease a psoriasis patient’s risk of developing PsA. To further assess the impact of treatment with biologics, Ms. Meer and associates retrospectively examined the health records of thousands of patients with psoriasis between the ages of 16 and 90 who were initiating therapy. All told, data from 193,709 patients with psoriasis and without PsA who were treated between 2006 and 2017 were gathered from the OptumInsights Electronic Health Record Database.

A total of 14,569 patients from that cohort initiated biologic therapy while 20,321 patients initiated either oral therapy or phototherapy. The mean age in the biologics group was 45.9 years, compared with 49.8 years in the oral and phototherapy group.

The incidence of PsA across all patients was 9.75 cases per 1,000 person-years, compared with 77.26 among the biologic group, 61.99 among the oral therapy group, 26.11 among the phototherapy group, and 5.85 among those who did not receive therapy. After a multivariable adjustment in which biologics were a time-varying exposure, receiving biologics was associated with a higher incidence of PsA (hazard ratio, 4.48; 95% confidence interval, 4.23-4.75). In a model where time starts at the first use of biologics, the incidence was lower – but still notable – after multivariable adjustment (HR, 2.14; 95% CI, 2.00-2.28) and propensity score matching (HR, 2.17; 95% CI, 2.03-2.33).

Bias likely plays a large role in retrospective PsA study

“We’ve been struggling for the last several years to find a database that allows us to really address this question retrospectively,” study coauthor Christopher T. Ritchlin, MD, of the University of Rochester (N.Y.), said in an interview. “It looks like the model you use for a retrospective analysis heavily influences what you come out with.”

He described the potential biases they identified, including the possibility of protopathic bias indicating that patients being treated with biologics who then report joint pain have developed PsA – and are coded accordingly after visiting a rheumatologist.

“This has convinced us that you have to do a prospective study,” he said. “We’ve known that there were flaws with previous studies in this area. We tried to overcome them with our methodology, but there’s no way you can overcome a coding issue when you’re looking at such a large database.”

He noted another likely bias: The patients who are more likely to develop PsA are the ones with severe psoriasis, and they are also the patients most likely to be prescribed biologics.

“In my clinical experience, I have seen many patients develop psoriatic arthritis while on biologics for their psoriasis,” coauthor Joel M. Gelfand, MD, of the University of Pennsylvania, added in an interview. “Currently, we do not have adequate data to recommend treating psoriasis with a particular modality in order to prevent psoriatic arthritis. This question, however, is very important to patients and clinicians and ultimately is best answered with a large-scale pragmatic trial.”

Dr. Ritchlin reported that a prospective study in which “patients with psoriasis who do not have arthritis but do have certain risk factors and abnormal findings on musculoskeletal ultrasounds” will be treated with either biologic agents or placebo is about to begin, with a goal of “either attenuating or preventing the onset of PsA.”

The authors recognized their study’s additional limitations, including electronic health records being used as the primary data source and the possibility that medications were prescribed but never filled. That said, they did attempt to address the latter by using two prescriptions for a given therapy as the primary analysis, “suggesting a refill was initiated.”

The authors said that no commercial entities provided support for the study. Two of the authors acknowledged receiving funding from the National Psoriasis Foundation, and several authors declared potential conflicts of interests that included consulting and receiving honoraria from various pharmaceutical companies.

A new study has found that patients with psoriasis who were treated with biologics were more likely to develop psoriatic arthritis (PsA) than those treated with phototherapy, oral therapy, or no therapy at all, although the authors cautioned readers to consider potential biases when reviewing their findings.

“We do not suggest that these results should be interpreted causally; in other words, biologics likely do not cause PsA,” Elana Meer of the University of Pennsylvania, Philadelphia, and coauthors wrote. The study was published in Annals of the Rheumatic Diseases.

Three studies in dermatology clinic-based populations published this past summer – one from Italy, one from Argentina, and one from Israel – suggested that biologics can decrease a psoriasis patient’s risk of developing PsA. To further assess the impact of treatment with biologics, Ms. Meer and associates retrospectively examined the health records of thousands of patients with psoriasis between the ages of 16 and 90 who were initiating therapy.

Deucravacitinib, a novel inhibitor of tyrosine kinase 2 (TYK2), continues to demonstrate strong efficacy and acceptable safety after 52 weeks of follow-up, according to late-breaking data from two pivotal trials presented at the virtual annual congress of the European Academy of Dermatology and Venereology.

From benefit reported on the two coprimary endpoints previously reported at 16 weeks, longer follow-up showed further gains out to 24 weeks and then persistent efficacy out to 52 weeks across these and multiple secondary endpoints, reported Richard Warren, MBChB, PhD, professor of dermatology and therapeutics, University of Manchester (England).

“This could be a unique oral therapy and an important treatment option for moderate to severe psoriasis,” Dr. Warren contended.

The multinational double-blind trials, called POETYK PSO-1 and PSO-2, enrolled 666 and 1,020 patients, respectively. The designs were similar. Patients with moderate to severe plaque psoriasis were randomly assigned in a 2:1:1 ratio to deucravacitinib (6 mg once daily), placebo, or apremilast (Otezla; 30 mg twice daily). At 16 weeks, those on placebo were switched to deucravacitinib.

For the coprimary endpoint of PASI 75 (75% clearance on the Psoriasis and Severity Index), the similar rate of response for deucravacitinib in the two studies (58.7%/53.6%) at week 16 was superior to the rates observed on both apremilast (35.1%/40.2%) and placebo (12.7%/9.4%).

By week 24, the proportion of deucravacitinib patients with a PASI 75 response had reached 69.3% and 58.7% in the POETYK PSO-1 and PSO-2 trials, respectively. The proportion of patients on apremilast with PASI 75 at this time point did not increase appreciably in one study and fell modestly in the other.

By week 52, the response rates achieved with deucravacitinib at week 24 were generally unchanged and nearly double those observed on apremilast.

The pattern of relative benefit on the other coprimary endpoint, which was a score of 0 or 1, signifying clear or almost clear skin on the static Physicians Global Assessment (sPGA), followed the same pattern. At week 16, 53.6% of patients had achieved sPGA 0/1. This was significantly higher than that observed on either apremilast or placebo, and this level of response was sustained through week 52.

When patients on placebo were switched to deucravacitinib at week 16, the PASI 75 response climbed quickly. There was complete catch-up by 32 weeks. In both groups, a PASI 75 response rate of about 65% or higher was maintained for the remainder of the study.

On a prespecified analysis, prior treatment exposure was not associated with any impact on the degree of response with deucravacitinib. This included a comparison between patients exposed to no prior biologic, one prior biologic, or two or more biologics, Dr. Warren reported.

Unlike patients in POETYK PSO-1, those with a PASI 75 response at 16 weeks in the POETYK PSO-2 trial were rerandomized to remain on deucravacitinib or switch to placebo. Designed to evaluate response durability, this analysis showed a relatively gradual decline in disease control.

“The median time to a loss of response was 12 weeks,” Dr. Warren said. He was referring in this case to the PASI 75 response, but the slope of decline was similar for sPGA score 0/1. At the end of 52 weeks, 31.3% of patients who had been rerandomized to placebo still maintained a PASI 75 while 80.4% of those who stayed on deucravacitinib still had PASI 75 clearance.

In the 52-week data from these two trials, several secondary endpoints have already been examined, and Dr. Warren said more analyses are coming. So far, the pattern of response has been similar for all endpoints.

Reporting on one as an example, Dr. Warren said that sPGA 0/1 for scalp psoriasis was achieved at week 16 by 70.3% of those randomly assigned to deucravacitinib versus 17.4% of those in the placebo arm. Among those switched from placebo to deucravacitinib at 16 weeks, the scalp response had caught up to that observed in those initiated on deucravacitinib by week 28. The response was sustained out to 52 weeks in both groups.

In the long-term trials, there have been no new safety concerns, according to Dr. Warren. He described this drug as “well tolerated,” adding that no significant laboratory abnormalities have been observed on long-term treatment. Although there has been a trend for increased risk of viral infections, such as herpes zoster, relative to apremilast, cases have so far been mild.

The Janus kinase inhibitor tofacitinib (Xeljanz, Xeljanz XR) has been approved for psoriatic arthritis, and numerous other JAK inhibitors are now in clinical trials for plaque psoriasis. These agents vary for their relative selectivity for JAK1, 2, and 3 kinases, but deucravacitinib is the first JAK inhibitor to reach clinical trials that target TYK2, which inhibits interleukin-23 and other cytokines implicated in the pathogenesis of plaque psoriasis.

“Deucravacitinib is very distinct from the other JAK inhibitors, and I think we are seeing this in the clinical studies,” Dr. Warren said. As a result of responses in the POETYK PRO trials that rival those achieved with monoclonal antibodies, he expects this drug, if approved, to be an important option for those with moderate to severe disease who prefer oral therapies.

Mark G. Lebwohl, MD, professor of dermatology and dean for clinical therapeutics, Icahn School of Medicine at Mount Sinai, New York, shares this opinion. In an interview, he emphasized the unique mechanism of deucravacitinib and its clinical potential.

“Unlike other less specific JAK inhibitors, deucravacitinib has a unique binding site on TYK2, the regulatory domain of the molecule. This makes deucravacitinib more targeted and therefore safer than other JAK inhibitors,” said Dr. Lebwohl.

“After cyclosporine, which has many side effects, deucravacitinib is the most effective oral therapy we have for psoriasis and one of the safest,” he added.

The POETYK PSO-1 and PSO-2 trials received funding from Bristol-Myers Squibb. Dr. Warren has financial relationships with AbbVie, Almirall, Boehringer Ingelheim, Celgene, Eli Lilly, Janssen, Leo Pharma, Novartis, Pfizer, Sanofi, UCB, and Xenoport. Dr. Lebwohl has financial relationships with more than 20 pharmaceutical companies, including Bristol-Myers Squibb.

It took years for Elle Moxley to get a diagnosis that explained her crippling gastrointestinal pain, digestion problems, fatigue, and hot, red rashes. And after learning in 2016 that she had Crohn’s disease, a chronic inflammation of the digestive tract, she spent more than 4 years trying medications before getting her disease under control with a biologic drug called Remicade.

So Ms. Moxley, 33, was dismayed to receive a notice from her insurer in January that Remicade would no longer be covered as a preferred drug on her plan. Another drug, Inflectra, which the Food and Drug Administration says has no meaningful clinical differences from Remicade, is now preferred. It is a “biosimilar” drug.

“I felt very powerless,” said Ms. Moxley, who recently started a job as a public relations coordinator for Kansas City (Mo.) Public Schools. “I have this decision being made for me and my doctor that’s not in my best interest, and it might knock me out of remission.”

After Ms. Moxley’s first Inflectra infusion in July, she developed a painful rash. It went away after a few days, but she said she continues to feel extremely fatigued and experiences gastrointestinal pain, constipation, diarrhea and nausea.

Many medical professionals look to biosimilar drugs as a way to increase competition and give consumers cheaper options, much as generic drugs do, and they point to the more robust use of these products in Europe to cut costs.

Yet the United States has been slower to adopt biosimilar drugs since the first such medicine was approved in 2015. That’s partly because of concerns raised by patients like Moxley and their doctors, but also because brand-name biologics have kept biosimilars from entering the market. The companies behind the brand-name drugs have used legal actions to extend the life of their patents and incentives that make offering the brand biologic more attractive than offering a biosimilar on a formulary, listing which drugs are covered on an insurance plan.

“It distorts the market and makes it so that patients can’t get access,” said Jinoos Yazdany, MD, MPH, a professor of medicine and chief of the rheumatology division at Zuckerberg San Francisco General Hospital.

The FDA has approved 31 biosimilar medications since 2015, but only about 60% have made it to market, according to an analysis by NORC, a research organization at the University of Chicago.

Remicade’s manufacturer, Johnson & Johnson, and Pfizer, which makes the Remicade biosimilar Inflectra, have been embroiled in a long-running lawsuit over Pfizer’s claims that Johnson & Johnson tried to choke off competition through exclusionary contracts with insurers and other anticompetitive actions. In July, the companies settled the case on undisclosed terms.

In a statement, Pfizer said it would continue to sell Inflectra in the United States but noted ongoing challenges: “Pfizer has begun to see progress in the overall biosimilars marketplace in the U.S. However, changes in policy at a government level and acceptance of biosimilars among key stakeholders are critical to deliver more meaningful uptake so patients and the health care system at large can benefit from the cost savings these medicines may deliver.”

Johnson & Johnson said it is committed to making Remicade available to patients who choose it, which “compels us to compete responsibly on both price and value.”

Biologic medicines, which are generally grown from living organisms such as animal cells or bacteria, are more complex and expensive to manufacture than drugs made from chemicals. In recent years, biologic drugs have become a mainstay of treatment for autoimmune conditions like Crohn’s disease and rheumatoid arthritis, as well as certain cancers and diabetes, among other conditions.

Other drugmakers can’t exactly reproduce these biologic drugs by following chemical recipes as they do for generic versions of conventional drugs.

Instead, biosimilar versions of biologic drugs are generally made from the same types of materials as the original biologics and must be “highly similar” to them to be approved by the FDA. They must have no clinically meaningful differences from the biologic drug, and be just as safe, pure and potent. More than a decade after Congress created an approval pathway for biosimilars, they are widely accepted as safe and effective alternatives to brand biologics.

Medical experts hope that as biosimilars become more widely used they will increasingly provide a brake on drug spending.

From 2015 to 2019, drug spending overall grew 6.1%, while spending on biologics grew more than twice as much – 14.6% – according to a report by IQVIA, a health care analytics company. In 2019, biologics accounted for 43% of drug spending in the United States

Biosimilars provide a roughly 30% discount over brand biologics in the United States but have the potential to reduce spending by more than $100 billion in the next 5 years, the IQVIA analysis found.

In a survey of 602 physicians who prescribe biologic medications, more than three-quarters said they believed biosimilars are just as safe and effective as their biologic counterparts, according to NORC.

But they were less comfortable with switching patients from a brand biologic to a biosimilar. While about half said they were very likely to prescribe a biosimilar to a patient just starting biologic therapy, only 31% said they were very likely to prescribe a biosimilar to a patient already doing well on a brand biologic.

It can be challenging to find a treatment regimen that works for patients with complicated chronic conditions, and physicians and patients often don’t want to rock the boat once that is achieved.

In Ms. Moxley’s case, for example, before her condition stabilized on Remicade, she tried a conventional pill called Lialda, the biologic drug Humira and a lower dose of Remicade.

Some doctors and patients raise concerns that switching between these drugs might cause patients to develop antibodies that cause the drugs to lose effectiveness. They want to see more research about the effects of such switches.

“We haven’t seen enough studies about patients going from the biologic to the biosimilar and bouncing back and forth,” said Marcus Snow, MD, chair of the American College of Rheumatology’s Committee on Rheumatologic Care. “We don’t want our patients to be guinea pigs.”

Manufacturers of biologic and biosimilar drugs have participated in advertising, exhibit or sponsorship opportunities with the American College of Rheumatology, according to ACR spokesperson Jocelyn Givens.

But studies show a one-time switch from Remicade to a biosimilar like Inflectra does not cause side effects or the development of antibodies, said Ross Maltz, MD, a pediatric gastroenterologist at Nationwide Children’s Hospital in Columbus, Ohio, and former member of the Crohn’s & Colitis Foundation’s National Scientific Advisory Committee. Studies may be conducted by researchers with extensive ties to the industry and funded by drugmakers.

Situations like Ms. Moxley’s are unusual, said Kristine Grow, senior vice president of communications at AHIP, an insurer trade group.

“For patients who have been taking a brand-name biologic for some time, health insurance providers do not typically encourage them to switch to a biosimilar because of a formulary change, and most plans exclude these patients from any changes in cost sharing due to formulary changes,” she said.

Drugmakers can seek approval from the FDA of their biosimilar as interchangeable with a biologic drug, allowing pharmacists, subject to state law, to switch a physician’s prescription from the brand drug, as they often do with generic drugs.

However, the FDA has approved only one biosimilar (Semglee, a form of insulin) as interchangeable with a biologic (Lantus).

Like Ms. Moxley, many other patients using biologics get copay assistance from drug companies, but the money often isn’t enough to cover the full cost. In her old job as a radio reporter, Ms. Moxley said, she hit the $7,000 maximum annual out-of-pocket spending limit for her plan by May.

In her new job, Ms. Moxley has an individual plan with a $4,000 maximum out-of-pocket limit, which she expects to blow past once again within months.

But she received good news recently: Her new plan will cover Remicade.

“I’m still concerned that I will have developed antibodies since my last dose,” she said. “But it feels like a step in the direction of good health again.”

It took years for Elle Moxley to get a diagnosis that explained her crippling gastrointestinal pain, digestion problems, fatigue, and hot, red rashes. And after learning in 2016 that she had Crohn’s disease, a chronic inflammation of the digestive tract, she spent more than 4 years trying medications before getting her disease under control with a biologic drug called Remicade.

So Ms. Moxley, 33, was dismayed to receive a notice from her insurer in January that Remicade would no longer be covered as a preferred drug on her plan.

In almost 80% of cases, cutaneous psoriasis predates the onset of arthritic psoriasis. Therefore, identifying risk factors for the development of psoriatic arthritis (PsA) in patients with skin psoriasis is of significant clinical and research interest. One such risk factor that has previous been described is the severity of psoriasis. In a prospective population-based cohort study performed within The Health Improvement Network in the UK, Ogdie et al demonstrated that in a cohort of 8881 patients aged 25–60 years with a code for psoriasis randomly selected between 2008 and 2011, the extent of psoriasis as measured by the body surface area affected (BSA) was a strong predictor of developing PsA. Comorbidities, such as obesity and depression, were additive risk factors. In this cohort, after a mean follow-up time of 4.2 years (SD 2.1), the incidence of PsA was 5.4 cases per 1000 person-years. After adjusting for age and sex, BSA > 10% [hazard ratio (HR) 2.01, 95% CI 1.29, 3.13], BSA 3–10% (HR 1.44, 95% CI 1.02, 2.03), obesity (HR 1.64, 95% CI 1.19, 2.26) and depression (HR 1.68, 95% CI 1.21, 2.33) were associated with incident PsA. Thus, patients with these risk factors should be carefully evaluated at each visit for signs of PsA.

One important question is whether treatment of psoriasis with targeted therapies reduces the risk of incident PsA. In a retrospective cohort study using the electronic medical records of the Maccabi Healthcare Services in Israel, Rosenthal et al, using propensity score matching compared patients who had received biological treatment for psoriasis and were not diagnosed with PsA before or at the time of biologic treatment initiation to controls not on such treatment. Patients were matched by age at diagnosis, gender, time until treatment initiation, maximum body mass index (BMI), and smoking. Multivariable Cox regression analysis showed that the control group had a significantly higher risk for PsA compared to patients treated with biologics (adjusted HR 1.39; 95%CI 1.03-1.87). Thus, there is increasing evidence that biologic therapy may decrease the risk of developing PsA.

Management of comorbidities remain an ongoing challenge in the management of psoriatic disease. In a cross-sectional multi-center study conducted by the Turkish League Against Rheumatism involving 1033 patients with PsA, 383 (37.1%) of whom were obese, Gok et al report that obesity was significantly associated with higher disease activity, lower quality of life scores, anxiety, depression, and fatigue. Comorbidities including obesity must be addressed for holistic management of PsA.

But counseling about modifiable risk factors remains low. Taylor et al reported that counseling or education for modifiable lifestyle risk factors were rare during psoriatic disease outpatient visits. Using data from the National Ambulatory Medical Care Survey (2002-2016) and the National Hospital Ambulatory Medical Care Survey (2002-2011) conducted in the United States, they demonstrate low rates of counseling for any modifiable lifestyle risk factor (11.1%; 95% CI 7.9%-15.3%), tobacco (4.8%; 95% CI 2.8%-8.0%), and obesity (2.8%; 95% CI 1.7%-4.5%). Thus, in addition to counseling about medications, an effort must be made to counsel about modifiable risk factors and comorbidities to improve quality of life of patients with psoriatic disease.

In almost 80% of cases, cutaneous psoriasis predates the onset of arthritic psoriasis. Therefore, identifying risk factors for the development of psoriatic arthritis (PsA) in patients with skin psoriasis is of significant clinical and research interest. One such risk factor that has previous been described is the severity of psoriasis. In a prospective population-based cohort study performed within The Health Improvement Network in the UK, Ogdie et al demonstrated that in a cohort of 8881 patients aged 25–60 years with a code for psoriasis randomly selected between 2008 and 2011, the extent of psoriasis as measured by the body surface area affected (BSA) was a strong predictor of developing PsA. Comorbidities, such as obesity and depression, were additive risk factors. In this cohort, after a mean follow-up time of 4.2 years (SD 2.1), the incidence of PsA was 5.4 cases per 1000 person-years. After adjusting for age and sex, BSA > 10% [hazard ratio (HR) 2.01, 95% CI 1.29, 3.13], BSA 3–10% (HR 1.44, 95% CI 1.02, 2.03), obesity (HR 1.64, 95% CI 1.19, 2.26) and depression (HR 1.68, 95% CI 1.21, 2.33) were associated with incident PsA. Thus, patients with these risk factors should be carefully evaluated at each visit for signs of PsA.

One important question is whether treatment of psoriasis with targeted therapies reduces the risk of incident PsA. In a retrospective cohort study using the electronic medical records of the Maccabi Healthcare Services in Israel, Rosenthal et al, using propensity score matching compared patients who had received biological treatment for psoriasis and were not diagnosed with PsA before or at the time of biologic treatment initiation to controls not on such treatment. Patients were matched by age at diagnosis, gender, time until treatment initiation, maximum body mass index (BMI), and smoking. Multivariable Cox regression analysis showed that the control group had a significantly higher risk for PsA compared to patients treated with biologics (adjusted HR 1.39; 95%CI 1.03-1.87). Thus, there is increasing evidence that biologic therapy may decrease the risk of developing PsA.

Management of comorbidities remain an ongoing challenge in the management of psoriatic disease. In a cross-sectional multi-center study conducted by the Turkish League Against Rheumatism involving 1033 patients with PsA, 383 (37.1%) of whom were obese, Gok et al report that obesity was significantly associated with higher disease activity, lower quality of life scores, anxiety, depression, and fatigue. Comorbidities including obesity must be addressed for holistic management of PsA.

But counseling about modifiable risk factors remains low. Taylor et al reported that counseling or education for modifiable lifestyle risk factors were rare during psoriatic disease outpatient visits. Using data from the National Ambulatory Medical Care Survey (2002-2016) and the National Hospital Ambulatory Medical Care Survey (2002-2011) conducted in the United States, they demonstrate low rates of counseling for any modifiable lifestyle risk factor (11.1%; 95% CI 7.9%-15.3%), tobacco (4.8%; 95% CI 2.8%-8.0%), and obesity (2.8%; 95% CI 1.7%-4.5%). Thus, in addition to counseling about medications, an effort must be made to counsel about modifiable risk factors and comorbidities to improve quality of life of patients with psoriatic disease.

The risk of developing psoriatic arthritis (PsA) may increase as the severity of psoriasis increases, results from a large analysis of U.S. medical records demonstrated.

Factors that predict the development of psoriasis in patients with psoriasis include nail, inverse, and scalp psoriasis; family history of PsA; as well as severity of skin disease. And like psoriasis, “PsA is associated with a multitude of comorbidities, including cardiovascular disease, metabolic syndrome, Crohn’s disease, obesity, diabetes, uveitis, anxiety, and depression, with correspondingly higher healthcare utilization and direct healthcare costs,” wrote corresponding author Joseph F. Merola, MD, MMSc, and colleagues. The study was published online in the Journal of the American Academy of Dermatology. “Timely and accurate diagnosis of PsA is important for improved patient outcomes and appropriate disease management and may prevent prolonged inflammation that leads to structural joint damage and worsening physical function,” they added.

The mean time of onset of PsA among patients with psoriasis who develop PsA is 10 years after the first signs of psoriasis appear. An estimated 20%-30% of patients with psoriasis have a concurrent diagnosis of PsA, and the annual incidence of PsA has been reported to be 2.7 cases per 100 patients with psoriasis. While previous studies have suggested that a higher incidence of PsA is associated with greater disease severity, there are limited data in the United States on the topic.

For the study, Dr. Merola, a dermatologist and rheumatologist who directs the Center for Skin and Related Musculoskeletal Diseases at Brigham and Women’s Hospital, Boston, and his colleagues drew from the Optum EHR database to identify adult patients newly diagnosed with psoriasis between Jan. 1, 2009, and March 31, 2019. Patients diagnosed with psoriasis or PsA prior to the index date were excluded from the analysis for evaluation of incidence but included for evaluation of prevalence. The patients were followed from the index date until the earliest PsA event, death, or end of study or follow-up, whichever came first. The researchers calculated the incidence of PsA among adults with psoriasis as the number of incident PsA events divided by the number of patient-years (PY) at risk, which was reported as the raw incidence per 100 psoriasis PY. They calculated the prevalence of PsA among adults with psoriasis as “the number of prevalent PsA events divided by the number of eligible patients with [psoriasis] and reported by years in the follow-up period,” which was a median of 3.7 years.

A total of 114,868 patients were included in the analysis. At baseline, their mean age was 54 years, 53% were female, 89% were White, and 39% were obese. Most patients (102,553) were on nonsystemic agents during the year after their psoriasis diagnosis, while 6,345 were on nonbiologic systemic therapies (NBSTs) and 5,970 were on biologics. The researchers classified patients as having mild psoriasis if they were taking nonsystemic agents, moderate disease if they were taking NBSTs, or severe disease if they were taking biologics.

The overall incidence rate of PsA was 2.9 events per 100 PY and increased by severity of disease. When calculated by severity, the incidence was 2.1 events per 100 PY for patients with mild psoriasis, 9.9 events per 100 PY for those with moderate psoriasis, and 17.6 events per 100 PY for those with severe psoriasis.

When the researchers excluded patients diagnosed with PsA up to 1 year after being diagnosed with psoriasis, the overall incidence was lower (1.7 events per 100 PY), with similar trends for categories of treatment severity. Specifically, the incidence was 1.5, 3.1, and 4.7 events per 100 PY among those with mild, moderate, and severe psoriasis, based on their treatment groups, respectively.

Among the 120,523 patients with psoriasis who were eligible for the assessment of prevalence of PsA, the overall 5-year prevalence of PsA was 14.2% and rose with severity of disease: 9.9% in patients with mild psoriasis, 35% in patients with moderate psoriasis, and 54.9% in patients with severe psoriasis.

Other predictors of PsA onset for both index-date cohorts included weight of 90 kg or greater, female gender, age group 25-65 years (compared with the age group over 65 years), and rheumatic risk factors such as wrist pain and unspecified rheumatism.

“To ensure timely diagnosis and treatment for management and prevention of PsA, patients with [psoriasis] should be routinely screened, especially those with more severe disease and other PsA risk factors,” the authors advised.

Dr. Merola and colleagues acknowledged certain limitations of their analysis, including the potential for selection bias and its reliance on EHR data which “lacked clinical measures of disease severity such as the PASI, and data on BSA were not available for all study participants; therefore, treatment groups were used as a surrogate for disease severity,” they wrote. “As a result, some patients may have been miscategorized, especially patients with severe disease who were untreated.”

The study was sponsored by Novartis. Dr. Merola disclosed that he is a consultant and/or investigator for Merck, AbbVie, Dermavant, Eli Lilly, Novartis, Janssen, UCB, Celgene, Sanofi, Regeneron, Arena, Sun Pharmaceuticals, Biogen, Pfizer, EMD Serono, Avotres, and LEO Pharma. Four authors are Novartis employees, or employees of a consulting company that provides services to Novartis; and another author disclosed serving as an investigator or consultant for several pharmaceutical companies, including Novartis.

High out-of-pocket costs for medications remain a barrier for patients with psoriasis or psoriatic arthritis on Medicare, according to findings from a cross-sectional analysis of the Centers for Medicare & Medicaid Services Prescription Drug Plan Formulary Data from the fourth quarter of 2020.

Mathier/Thinkstock

Although biologics have demonstrated safety and effectiveness for psoriasis and psoriatic arthritis, their costs have risen, which has led patients to switch or discontinue biologics and consequently incur greater health care costs, wrote Sarah P. Pourali and colleagues at Vanderbilt University, Nashville, Tenn.

The authors also noted that Medicare patients in particular experience a financial burden if they have no limits on out-of-pocket spending, and while patient assistance programs may offset some out-of-pocket spending for specialty drugs, not all patients are aware of or qualify for them. Ineligibility for low-income subsidies also serves as a barrier and is associated with lower adherence to treatment.

In a study published in JAMA Dermatology, the researchers identified 5,011 formularies using the CMS data. The medications were etanercept, adalimumab, golimumab, ustekinumab, certolizumab pegol, apremilast, secukinumab, abatacept, ixekizumab, brodalumab, tofacitinib, tofacitinib XR, guselkumab, tildrakizumab, and risankizumab.

Overall, coverage for those 15 specialty medications ranged from 10.0% to 99.8% across products and Part D plans. The most commonly covered medications were adalimumab and ustekinumab (99.8% for both) and the least covered were brodalumab and tildrakizumab (10.9% and 10.0%, respectively).

Prior authorization was required by 90.5%-100% of the plans when medications were covered, and plans with limits on the quantity of medications covered ranged from 1.0% of plans (for guselkumab) to 78% of plans (for tofacitinib).

Copays were relatively rare; 2.4%-5.5% of the plans offered copays on any of the 15 medications.

The standard Medicare benefit for 2021 included a $445 deductible, 25% coinsurance for initial drug spending, and 5% coinsurance for drug spending in the catastrophic phase of coverage, the researchers noted. Overall, apremilast had the lowest estimated out-of-pocket costs for initial fills, under the catastrophic coverage phase, and annual cost, and ustekinumab had the highest. The estimated out-of-pocket costs for an initial fill ranged from $1,234 for apremilast to $3,426 for ustekinumab. Out-of-pocket costs for medications under the catastrophic phase ranged from $181 for apremilast to $1,175 for ustekinumab. Estimated out-of-pocket costs for a year of treatment ranged from $4,423 for apremilast to $6,950 for ustekinumab.

Median point-of-sale prices per fill – meaning pricing with no rebates or discounts – were lowest for apremilast ($3,620.40) and reached $23,492.93 per fill for ustekinumab, the researchers wrote. Other medications with point-of-sale prices above $10,000 were guselkumab ($11,511.52), tildrakizumab ($14,112.13), and risankizumab ($16,248.90).

The study was supported by grants from the Commonwealth Fund and the Leukemia & Lymphoma Society. One author disclosed receiving grants from Arnold Ventures, the Commonwealth Fund, and the Robert Wood Johnson Foundation for unrelated work, as well as honoraria from West Health and the Institute for Clinical and Economic Review.

Overall, coverage for those 15 specialty medications ranged from 10.0% to 99.8% across products and Part D plans. The most commonly covered medications were adalimumab and ustekinumab (99.8% for both) and the least covered were brodalumab and tildrakizumab (10.9% and 10.0%, respectively).

Prior authorization was required by 90.5%-100% of the plans when medications were covered, and plans with limits on the quantity of medications covered ranged from 1.0% of plans (for guselkumab) to 78% of plans (for tofacitinib).

Copays were relatively rare; 2.4%-5.5% of the plans offered copays on any of the 15 medications.

The standard Medicare benefit for 2021 included a $445 deductible, 25% coinsurance for initial drug spending, and 5% coinsurance for drug spending in the catastrophic phase of coverage, the researchers noted. Overall, apremilast had the lowest estimated out-of-pocket costs for initial fills, under the catastrophic coverage phase, and annual cost, and ustekinumab had the highest. The estimated out-of-pocket costs for an initial fill ranged from $1,234 for apremilast to $3,426 for ustekinumab. Out-of-pocket costs for medications under the catastrophic phase ranged from $181 for apremilast to $1,175 for ustekinumab. Estimated out-of-pocket costs for a year of treatment ranged from $4,423 for apremilast to $6,950 for ustekinumab.

Median point-of-sale prices per fill – meaning pricing with no rebates or discounts – were lowest for apremilast ($3,620.40) and reached $23,492.93 per fill for ustekinumab, the researchers wrote. Other medications with point-of-sale prices above $10,000 were guselkumab ($11,511.52), tildrakizumab ($14,112.13), and risankizumab ($16,248.90).

High out-of-pocket costs for medications remain a barrier for patients with psoriasis or psoriatic arthritis on Medicare, according to findings from a cross-sectional analysis of the Centers for Medicare & Medicaid Services Prescription Drug Plan Formulary Data from the fourth quarter of 2020.

Although biologics have demonstrated safety and effectiveness for psoriasis and psoriatic arthritis, their costs have risen, which has led patients to switch or discontinue biologics and consequently incur greater health care costs, wrote Sarah P. Pourali and colleagues at Vanderbilt University, Nashville, Tenn.

The authors also noted that Medicare patients in particular experience a financial burden if they have no limits on out-of-pocket spending, and while patient assistance programs may offset some out-of-pocket spending for specialty drugs, not all patients are aware of or qualify for them. Ineligibility for low-income subsidies also serves as a barrier and is associated with lower adherence to treatment.
