PHILADELPHIA – Aggressive therapy using conventional synthetic disease-modifying antirheumatic drugs (DMARDs) in combination with biologic agents early, soon after a child is diagnosed with polyarticular juvenile idiopathic arthritis (pJIA), enabled more patients to achieve clinical remission and longer times in inactive disease than more conventional therapeutic approaches, 3-year results of prospective, observational study demonstrated.

The results of The Childhood Arthritis and Rheumatology Research Alliance STOP-JIA study, which Yukiko Kimura, MD, presented at the annual meeting of the American College of Rheumatology, showed early combination therapy had benefits, compared with other treatment strategies that were more evident at 3 years than at 1 year of study.

“The STOP-JIA study showed that, after 3 years, patients who started a biologic early on in combination with methotrexate spent more time in inactive disease and achieved clinical remission more often when compared to those started on traditional step-up therapy,” Dr. Kimura, chief of pediatric rheumatology at Hackensack (N.J.) Meridian Health and professor of pediatrics at the Hackensack Meridian School of Medicine, said at a press conference. “This study shows that the treatment of poly-JIA patients receive initially very early on in their disease matters even 3 years after that treatment was started.”

The study compared three CARRA consensus treatment plans (CTP) for untreated pediatric pJIA patients: step-up (SU) – starting conventional synthetic DMARD therapy and adding a biologic if needed after 3 or more months; early-combination (EC) therapy – starting synthetic and biologic DMARDs together; and biologic first (BF) therapy – starting biologic DMARD monotherapy.

Dr. Kimura explained the rationale for the study. “Since biologic treatments were introduced more than 20 years ago, the prognosis for JIA significantly improved. These very effective medicines often work wonders, quickly reducing pain and inflammation in joint disease activity,” she said in the press conference. “What is not known, however, is when is the best time to start these very effective treatments.”

The most common approach is to start with a synthetic DMARD, typically methotrexate, and wait before starting a biologic, Dr. Kimura said.

“But even though methotrexate can work very well by itself, it does not work for every patient, and we don’t know whether waiting months for it to work and then starting a biologic might potentially lessen their effectiveness,” Dr. Kimura added. “We don’t know if there’s a window of opportunity that’s lost while waiting to see whether methotrexate will work.”

The study originally enrolled 400 patients, 297 of whom completed the 3-year visit – 190 in SU, 76 in EC and 31 in BF. At 12 months, the study found no statistically significant difference in clinically inactive disease (CID) between the groups, Dr. Kimura said.

Even at the 3-year visit, the percentage of patients in CID off glucocorticoids and clinical Juvenile Arthritis Disease Activity Score based on 10 joints inactive disease (cJADAS 10 ID) did not differ among the three groups, Dr. Kimura said in presenting the results. “But,” she added, “greater proportions of early-combination CTP group were able to achieve clinical remissions and spend more time with inactive disease in both CID and cJADAS 10.”

A closer look at the outcomes showed some separation between early-combination therapy and the other two treatment plans. The incidence of clinical remission (at any time point over 36 months) was 67.1% in the EC group vs. 49.1% and 47.3%, respectively, in the BF and SU groups, Dr. Kimura said. “The difference between the early-combination and step-up groups was highly significant [P = .007],” she added.

EC also had an edge in the percentage of time patients spent in CID (over 36 months): 39.2% versus 32% and 27.4%, respectively, in the BF and SU groups (P = .006 for EV vs. SU), as well as cJADAS 10 ID (50.6% in EC group vs. 42.8% and 37.5%, respectively in the BF and SU groups; P = .005 for EC vs. SU).

Dr. Kimura said that the STOP JIA trial will continue with longer-term analysis and ongoing monitoring of study patients through the CARRA registry. “These longer-term analyses and readouts will be important because even though the results at 12 months didn’t seem as definitive, it seems the longer we go, the more impact we see of the treatments that were started early on in this disease.”

The findings from this study are “significantly important,” Nina T. Washington, MD, MPH, a pediatric rheumatologist at the University of New Mexico Hospital, Albuquerque, and the Mary Bridge Children’s Hospital in Tacoma, Wash., said in an interview. “At least for the past decade we’ve really been advocating towards earlier and aggressive therapy, and that’s what this study shows: the sooner you can treat this disease, the sooner you can attack those joints that are inflamed, the better outcome you give the patient.”

The study also confirms that pediatric rheumatologists are not overtreating patients with pJIA, she added.

“In a sense we’re actually treating and preventing and if you have a child that has arthritis, it’s okay to treat that child,” Dr. Washington said. “For me that’s the most reassuring thing: that I’m not necessarily going overboard. If I have a child with polyarticular JIA and they have multiple inflamed joints and I have the evidence as they’re sitting in front of me, and I treat them. I’m going to give them the best outcome.”

The Patient Centered Outcomes Research Institute provided study funding. Dr. Kimura is chair of the CARRA JIA disease research committee and cochair of the CARRA Registry and Research Oversight Committee. She disclosed a financial relationship with Genentech. Dr. Washington has no relevant relationships to disclose.

PHILADELPHIA – Patients with systemic lupus erythematosus treated with lower doses of hydroxychloroquine (HCQ) had an increased risk for hospitalization for flares, according to study results presented during a press conference at the annual meeting of the American College of Rheumatology.

Doses decreased with changing guidelines

Guidelines over the years have recommended decreasing doses of HCQ. In 2011, ophthalmology guidelines recommended limiting HCQ dosing to 6.5 mg/kg per day or less of ideal body weight to reduce the chance of retinopathy. For many patients, this required a dose lower than 400 mg/day, an amount frequently used to treat lupus.

In 2016, updated guidelines further lowered the dosage of HCQ, recommending 5 mg/kg or less of patient’s actual body weight.

The effects that lower dosing has had on SLE-associated hospitalizations was unknown, which inspired Dr. Nestor’s research.

The team conducted a case-crossover study within the Mass General Brigham SLE cohort.

Hospitalizations studied over a decade

Dr. Nestor and colleagues identified patients with SLE (via electronic health records) who had at least one visit for SLE and were prescribed HCQ between January 2011 and December 2021, the period over which the recommendations were made.

They identified patients who had been hospitalized during that decade with SLE as the primary discharge diagnosis.

Patients were excluded if they had non-SLE indications, such as kidney transplant or infection without a concomitant SLE flare.

Of 2,971 patients with SLE who used HCQ, 576 had at least one hospitalization with primary discharge diagnosis of SLE.

Of these, 108 were hospitalized for an SLE flare and had used HCQ prior to that hospitalization and had at least one control period with HCQ use during the study period.

All of the patients in the study had to have a case period and a control period, Dr. Nestor explained. The case period was 6 months on HCQ ending in hospitalization for lupus and the control period was 6 months on HCQ that did not end in hospitalization for lupus.
 

Significantly increased hospitalizations

Low-dose HCQ by weight-based dose (≤ 5 vs. > 5 mg/kg per day) and by non–weight-based dose (< 400 vs. 400 mg per day) were both associated with significantly increased hospitalizations for SLE (adjusted odds ratio, 4.41; 95% confidence interval, 1.50-12.98; and AOR, 3.48; 95% CI, 1.33-9.13, respectively).

The average age of the hospitalized group was 36 years. Most patients (92%) were female, 43.5% were White, and 32.4% were Black.

In calling for reassessment of the dosing, Dr. Nestor said, “We are protecting our patients against a very long-term side effect of hydroxychloroquine retinopathy. [It] typically takes 10-20 years to develop in our patients. But by doing that, we’re missing many of the short-term benefits from hydroxychloroquine in our patients, leading to more lupus flares, which leads to more end-organ damage.”

She said patients taking HCQ for lupus are asked to see an ophthalmologist once a year to monitor for the side effect, adding that rheumatologists and ophthalmologists could work together to adjust the guidelines.

Dr. Nestor suggested it’s possible that patients need higher doses of HCQ earlier in their disease and lower doses later. “Perhaps it’s just the patients who are particularly active who need the higher doses,” she said.

PHILADELPHIA – Oral remibrutinib was well tolerated and had a good safety profile over 24 weeks among patients with moderate to severe Sjögren syndrome (SS), according to new phase 2 data presented at the annual meeting of the American College of Rheumatology.

Thomas Dörner, MD, with the department of rheumatology and clinical immunology at Charité Universitätsmedizin Berlin, presented the data from the double-blind, randomized, placebo-controlled, proof-of-concept study.

The authors said the results of the study suggest that remibrutinib, a highly specific inhibitor of Bruton tyrosine kinase, has the potential to become the first effective oral disease-modifying therapy for SS.

The 73 participants in the study had moderate to severe SS. The baseline EULAR Sjögren Syndrome Disease Activity Index (ESSDAI) score was at least 5, EULAR Sjögren Syndrome Patient Reported Index (ESSPRI) was at least 5, and anti-Ro/SSA antibody positivity was 3 months or less before screening. The patients’ unstimulated whole salivary flow rate was > 0 mL/min.

Overall, 73 patients (71 women) were randomly assigned to receive either remibrutinib 100 mg twice a day (n = 24), remibrutinib 100 mg four times a day (n = 25), or placebo (n = 24) between August 2019 and May 2021.

Remibrutinib met the primary endpoint and resulted in a statistically significant improvement in ESSDAI score for both regimens combined compared with placebo at week 24 (ESSDAI, –2.86).
 

Patient-reported outcomes similar to placebo

Patient-reported outcomes, including scores on ESSPRI, Functional Assessment of Chronic Illness Therapy–Fatigue, and EuroQol-5 Dimension, were similar in the treatment groups and the placebo group.

“All of the patients, including the placebo patients, improved over the time of the study,” Dr. Dörner said.

The average age of the patients was 51.8 years (range, 18-75 years). Groups were generally balanced with regard to demographic qualities and disease severity at baseline, and the patients represented the SS population well, Dr. Dörner said.

No severe adverse events were reported. Infections were the most frequently reported adverse events, and the rates were similar with the study drug and placebo. No notable liver abnormalities were reported in any of the groups.

Chrisanna Dobrowolski, MD, assistant professor of medicine at Icahn School of Medicine at Mount Sinai in New York, told this news organization, “Preliminary results are promising, but they failed to show improvements in patient-reported quality-of-life measures.

“Having statistical improvements in disease activity measures without clinically meaningful improvement in patient quality of life may limit the value of this treatment,” she said.

Dr. Dobrowolski added that the follow-up period of 6 months is short, and larger studies over a longer period are needed to better assess the effect on patients’ quality of life.

“Regardless, this is the first oral medication which has shown disease-modifying potential for the glandular symptoms of SS and is an exciting new avenue of investigation to be further explored,” she said.

Patients with SS 15 to 20 times more likely to develop B-cell lymphoma as a life-threatening complication. SS is a systemic autoimmune disease characterized by B-cell hyperactivation, lymphoid infiltration, progressive destruction of exocrine glands, and various complications outside the glands, the study authors wrote in the abstract.
 

Nearly 4 million in U.S. live with the disease

Nearly 4 million people in the United States live with the disease. Common symptoms include light sensitivity, dry eye, dry mouth, fatigue, and joint pain.

SS can be difficult to diagnose because the symptoms vary from person to person and can be confused with those caused by other diseases.

Ardy Fenando, MD, a rheumatology fellow with the University of Kansas Medical Center, said in an interview, “We need more therapies for Sjögren’s. Heterogeneity complicates the way we set the primary endpoints. Therefore, we haven’t had a proven treatment for Sjögren’s. This is supported by previous RCTs [randomized controlled trials] that failed to meet the primary end points.”

Dr. Dörner has relationships with AbbVie, Eli Lilly, Roche/Genentech, Janssen, Novartis, Bristol-Myers Squibb), and UCB. Other authors have various relationships with industry. Dr. Fenando and Dr. Dobrowolski have disclosed no relevant financial relationships.

Chrisanna Dobrowolski, MD, assistant professor of medicine at Icahn School of Medicine at Mount Sinai in New York, told this news organization, “Preliminary results are promising, but they failed to show improvements in patient-reported quality-of-life measures.

“Having statistical improvements in disease activity measures without clinically meaningful improvement in patient quality of life may limit the value of this treatment,” she said.

Dr. Dobrowolski added that the follow-up period of 6 months is short, and larger studies over a longer period are needed to better assess the effect on patients’ quality of life.

“Regardless, this is the first oral medication which has shown disease-modifying potential for the glandular symptoms of SS and is an exciting new avenue of investigation to be further explored,” she said.

Patients with SS 15 to 20 times more likely to develop B-cell lymphoma as a life-threatening complication. SS is a systemic autoimmune disease characterized by B-cell hyperactivation, lymphoid infiltration, progressive destruction of exocrine glands, and various complications outside the glands, the study authors wrote in the abstract.
 

Nearly 4 million in U.S. live with the disease

Nearly 4 million people in the United States live with the disease. Common symptoms include light sensitivity, dry eye, dry mouth, fatigue, and joint pain.

SS can be difficult to diagnose because the symptoms vary from person to person and can be confused with those caused by other diseases.

Ardy Fenando, MD, a rheumatology fellow with the University of Kansas Medical Center, said in an interview, “We need more therapies for Sjögren’s. Heterogeneity complicates the way we set the primary endpoints. Therefore, we haven’t had a proven treatment for Sjögren’s. This is supported by previous RCTs [randomized controlled trials] that failed to meet the primary end points.”

PHILADELPHIA – Oral remibrutinib was well tolerated and had a good safety profile over 24 weeks among patients with moderate to severe Sjögren syndrome (SS), according to new phase 2 data presented at the annual meeting of the American College of Rheumatology.

Thomas Dörner, MD, with the department of rheumatology and clinical immunology at Charité Universitätsmedizin Berlin, presented the data from the double-blind, randomized, placebo-controlled, proof-of-concept study.

The authors said the results of the study suggest that remibrutinib, a highly specific inhibitor of Bruton tyrosine kinase, has the potential to become the first effective oral disease-modifying therapy for SS.

The 73 participants in the study had moderate to severe SS. The baseline EULAR Sjögren Syndrome Disease Activity Index (ESSDAI) score was at least 5, EULAR Sjögren Syndrome Patient Reported Index (ESSPRI) was at least 5, and anti-Ro/SSA antibody positivity was 3 months or less before screening. The patients’ unstimulated whole salivary flow rate was > 0 mL/min.

Overall, 73 patients (71 women) were randomly assigned to receive either remibrutinib 100 mg twice a day (n = 24), remibrutinib 100 mg four times a day (n = 25), or placebo (n = 24) between August 2019 and May 2021.

Remibrutinib met the primary endpoint and resulted in a statistically significant improvement in ESSDAI score for both regimens combined compared with placebo at week 24 (ESSDAI, –2.86).
 

Patient-reported outcomes similar to placebo

Patient-reported outcomes, including scores on ESSPRI, Functional Assessment of Chronic Illness Therapy–Fatigue, and EuroQol-5 Dimension, were similar in the treatment groups and the placebo group.

“All of the patients, including the placebo patients, improved over the time of the study,” Dr. Dörner said.

The average age of the patients was 51.8 years (range, 18-75 years). Groups were generally balanced with regard to demographic qualities and disease severity at baseline, and the patients represented the SS population well, Dr. Dörner said.

No severe adverse events were reported. Infections were the most frequently reported adverse events, and the rates were similar with the study drug and placebo. No notable liver abnormalities were reported in any of the groups.

PHILADELPHIA – When patients with inflammatory rheumatic diseases were switched from one biosimilar agent to another, treatment retention rates were high, investigators in Denmark reported.

The findings suggest patient-related factors rather than drug-related factors appear to determine whether patients will stay on the new drug, the researchers said.

One year after a Danish government-mandated switch from one infliximab (Remicade) biosimilar to another equally efficacious but less costly biosimilar, 83% of patients who had started therapy on a biosimilar (so-called “originator-naive” patients) stayed on the newly assigned therapy. And so did 92% of patients who had started on the original infliximab (“originator experienced”) before they were switched to one biosimilar and then another.

“In regards to potential baseline predictors, we found that treatment withdrawal was more frequent among originator-naive switchers and patients with higher baseline disease activity, especially [in] patient-reported outcomes, which may indicate that treatment-related outcomes may be more affected by patient-related rather than drug-related factors,” said lead author Hafsah Nabi, MD from the Danish biosimilar registry DANBIO and a PhD candidate at the Copenhagen Center for Arthritis Research.

Dr. Nabi reported the results in an oral abstract session at the annual meeting of the American College of Rheumatology.
 

Annual review of biologic agents

In Denmark, health authorities issue annual recommendations for the use of biologic agents. “And since patients receive this treatment free from the hospital, based on the tax system, the switches are made due to these cost considerations,” Dr. Nabi said in an interview.

To get the nod from Danish pharmaceutical regulators, pharmaceutical manufacturers submit drugs that have already been approved by the European Medicines Agency for consideration for treatment of specific indications, explained coauthor Merete Lund Hetland, MD, PhD, DMSc, from Rigshospitalet in Copenhagen.

“Those drugs that are then considered equally safe and effective are invited to this process where they will give their bid, and then the cheapest one will win,” she said.

The winning formulation will be able to capture about 80% of prescriptions for that indication for the coming year.
 

Awake at the switch

Dr. Nabi, Dr. Hetland, and colleagues studied how one such recent government-mandated switch from one biosimilar to another affected efficacy and patterns of care among patients with rheumatoid arthritis, psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA).

To identify prior comorbidities, they drew data from the DANBIO registry, which is linked to patient specific but anonymous data from other comprehensive birth-to-death patient registries in Denmark.

They looked at all patients with RA, PsA, or axSpA who were switched from CT-P13 (Remsira, Inflectra) to GP1111 (Zessly) from April 1, 2019, to Feb. 1, 2020.

They identified a total of 1,605 patients, including 685 with RA, 314 with PsA, and 606 with axSpa. The median disease duration was 9 years, and 37% of all patients were in remission according to Clinical Disease Activity Index or Ankylosing Spondylitis Disease Activity Scale.

Of this group, 1,171 had started therapy on a biosimilar.

As noted above, 83% of patients who had never received original infliximab, and 92% of those who were originator experienced were still on the new biosimilar 1 year after the switch.

In a multivariate analysis controlling for demographic and clinical factors at baseline, the variables significantly associated with treatment withdrawal from the new biosimilar (GP11110) included previous Remicade exposure (hazard ratio, 0.36), methotrexate use (HR, 0.60), and patient-reported global visual analog scale (HR, 1.02).

Among all patients, disease activity was stable 6 months before and after the switch, Dr. Nabi said, although she did not show data to support it.
 

Patient education benefit

During the session, Jonathan Kay, MD, professor of rheumatology and chair of the division of rheumatology at the University of Massachusetts, Worcester, who was not involved the study, asked Dr. Nabi whether patients were educated about equivalent efficacy and safety of biosimilars prior to the switch. He noted that education prior to switching led to a much lower patient withdrawal rate in a similar switching study conducted in The Netherlands.

“In this study, we haven’t looked more specifically into the education and which strategies have been used prior to switching, and we also conclude in the study that there may be the presence of a nocebo effect, which can be handled by better educating the patients,” she replied.

The nocebo effect refers to the phenomenon in which a patient’s belief that a specific intervention may cause harm actually can lead to negative outcomes – in other words, the opposite of the placebo effect.

In an interview, Dr. Kay said that he is confident about the efficacy, safety, and equivalency of approved biosimilar agents.

“A biosimilar that has been reviewed and approved by a regulatory agency such as the [Food and Drug Administration or the [European Medicines Agency] should be equivalent in efficacy and comparable in safety and immunogenicity. I would be fully confident in switching from the reference product to the biosimilar,” he said.

Dr. Nabi reported that the study was partly funded by a research grant from Sandoz, the maker of GP1111. Dr. Hetland has disclosed grants from various companies, not including Sandoz. Dr. Kay disclosed consulting fees from various companies, not including Sandoz.

PHILADELPHIA – In the first controlled clinical trial to compare the two drugs, rituximab and cyclophosphamide were similarly effective in improving lung function in patients with interstitial lung disease (ILD) associated with idiopathic inflammatory myositis and mixed connective tissue disease (CTD). The findings also revealed some nuanced findings that could help clarify which drug to use in specific patients.

“We feel that rituximab is a reasonable alternative to cyclophosphamide as a treatment in patients with these diseases,” said Toby Maher, MD, of the University of Southern California, Los Angeles, who presented results of an analysis of three disease subgroups from the RECITAL (Rituximab versus Cyclophosphamide for the Treatment of Connective Tissue Disease Associated Interstitial Lung Disease) study at the annual meeting of the American College of Rheumatology.

“We didn’t show it to be better, so I think you can reasonably choose between the two, but rituximab almost certainly has the advantage of being safer and better tolerated than cyclophosphamide,” Dr. Maher said in an interview. The findings were published simultaneously in The Lancet Respiratory Medicine.
 

Double-blind, double-dummy

RECITAL is a phase 2b, randomized, controlled trial to test the hypothesis that intravenous rituximab would be superior to cyclophosphamide for ILD-associated CTD.

The study included adults with three separate diagnoses: myositis (n = 44), mixed CTD (n = 16), and systemic sclerosis (SSc, n = 37). The study was done in the United Kingdom when Dr. Maher was with Imperial College London.

Patients in the rituximab group received 1,000 mg of IV treatment at baseline and 2 weeks, then placebo treatment every 4 weeks to week 20. Cyclophosphamide patients received 600 mg/m² of body surface area intravenously every 4 weeks for six doses.

“When we designed this study there was limited evidence for any treatment for any disease associated with ILD,” Dr. Maher said. “But cyclophosphamide brings with it many challenges. It can be poorly tolerated and carries issues like infertility and risk of bladder cancer.”
 

Improved lung function

While the study failed to meet its primary endpoint – superiority of rituximab versus cyclophosphamide – it did show that both drugs led to improvement in lung function, measured by the rate of change in forced vital capacity (FVC), as well as quality of life measures, Dr. Maher said.

“Overall by week 48, we saw about a 5% improvement in FVC in the cyclophosphamide group and approximately a 4% improvement in FVC from baseline in the rituximab group, suggesting that both drugs almost certainly had a positive benefit in this patient group,” he said.

But secondary outcomes varied somewhat across the different disease groups. Patients with SSc saw a slight deterioration with cyclophosphamide in the modified Rodnan skin score at 24 weeks (1.6 ± 5.7 units) but an improvement with rituximab (–3.4 ± 8.1 units).

“One area where we did see a difference was in the number of adverse events,” Dr. Maher said. “They were fewer in the rituximab arm – namely gastrointestinal disorders [and] nausea, which we saw quite frequently following cyclophosphamide. Also, they had fewer headaches, which we saw quite frequently following cyclophosphamide.”

Rituximab patients also had fewer infusion reactions, but the number of infections was similar between the two treatment groups, he said.

“The patient group that responded best to treatment was the myositis group,” Dr. Maher said in his presentation. “Cyclophosphamide actually appears to be more effective than rituximab in improving their disease. By the end of 48 weeks, the cyclophosphamide group actually gained about 400 mL in FVC, so a close to 20% improvement.”

The rituximab group had “a little bit of a drop-off” in efficacy from weeks 24 to 48, although the trial didn’t repeat dosing at 6 months, “which is what perhaps one might do in clinical practice,” he said.

Oliver Distler, MD, chair of rheumatology at the University Hospital Zürich, raised questions about concurrent corticosteroid use in study patients that may have caused a “spillover” in the study’s efficacy analysis. But Dr. Maher noted that steroid use was balanced in all treatment arms. Patients in the cyclophosphamide arm averaged 42.9 mg of hydrocortisone daily versus 37.6 mg daily in the rituximab arm. That represents a 12.3% reduction in steroid exposure for the latter.

Dr. Distler noted that the myositis population represented the bulk of those study patients on steroids. “So in the myositis subanalysis we do see a combination of high-dose steroid plus cyclophosphamide and rituximab.”

Dr. Maher disclosed relationships with Boehringer Ingelheim, Genentech, GlaxoSmithKline, Bristol-Myers Squibb, AstraZeneca, Trevi, CSL Behring, Pliant and Veracyte. Dr. Distler disclosed relationships with numerous pharmaceutical companies.

“When we designed this study there was limited evidence for any treatment for any disease associated with ILD,” Dr. Maher said. “But cyclophosphamide brings with it many challenges. It can be poorly tolerated and carries issues like infertility and risk of bladder cancer.”
 

Improved lung function

While the study failed to meet its primary endpoint – superiority of rituximab versus cyclophosphamide – it did show that both drugs led to improvement in lung function, measured by the rate of change in forced vital capacity (FVC), as well as quality of life measures, Dr. Maher said.

“Overall by week 48, we saw about a 5% improvement in FVC in the cyclophosphamide group and approximately a 4% improvement in FVC from baseline in the rituximab group, suggesting that both drugs almost certainly had a positive benefit in this patient group,” he said.

But secondary outcomes varied somewhat across the different disease groups. Patients with SSc saw a slight deterioration with cyclophosphamide in the modified Rodnan skin score at 24 weeks (1.6 ± 5.7 units) but an improvement with rituximab (–3.4 ± 8.1 units).

“One area where we did see a difference was in the number of adverse events,” Dr. Maher said. “They were fewer in the rituximab arm – namely gastrointestinal disorders [and] nausea, which we saw quite frequently following cyclophosphamide. Also, they had fewer headaches, which we saw quite frequently following cyclophosphamide.”

Rituximab patients also had fewer infusion reactions, but the number of infections was similar between the two treatment groups, he said.

“The patient group that responded best to treatment was the myositis group,” Dr. Maher said in his presentation. “Cyclophosphamide actually appears to be more effective than rituximab in improving their disease. By the end of 48 weeks, the cyclophosphamide group actually gained about 400 mL in FVC, so a close to 20% improvement.”

The rituximab group had “a little bit of a drop-off” in efficacy from weeks 24 to 48, although the trial didn’t repeat dosing at 6 months, “which is what perhaps one might do in clinical practice,” he said.

Oliver Distler, MD, chair of rheumatology at the University Hospital Zürich, raised questions about concurrent corticosteroid use in study patients that may have caused a “spillover” in the study’s efficacy analysis. But Dr. Maher noted that steroid use was balanced in all treatment arms. Patients in the cyclophosphamide arm averaged 42.9 mg of hydrocortisone daily versus 37.6 mg daily in the rituximab arm. That represents a 12.3% reduction in steroid exposure for the latter.

Dr. Distler noted that the myositis population represented the bulk of those study patients on steroids. “So in the myositis subanalysis we do see a combination of high-dose steroid plus cyclophosphamide and rituximab.”

Dr. Maher disclosed relationships with Boehringer Ingelheim, Genentech, GlaxoSmithKline, Bristol-Myers Squibb, AstraZeneca, Trevi, CSL Behring, Pliant and Veracyte. Dr. Distler disclosed relationships with numerous pharmaceutical companies.






 

Researchers have found a link between age of diagnosis and various clinical characteristics and outcomes in patients with antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV).

The findings, presented at the annual meeting of the American College of Rheumatology, may have implications for research and treatment, especially in children.

AAV is a group of conditions characterized by the development of autoantibodies to the neutrophil proteins proteinase 3 (PR3-ANCA) or myeloperoxidase (MPO-ANCA).

The rare autoimmune condition can cause systemic inflammation and damage, sometimes permanent, to small- and medium-sized arteries. Clinical presentations vary and can include several organs, including skin, stomach, intestines, lung, and kidney, as well as airways in ear, nose, and throat.
 

Data limited on child vs. adult characteristics

AAV can be diagnosed in any decade of life, but clinical characteristics and outcomes often differ between children and adults, and data are limited. Studies often exclude children.

Lead author Jessica Bloom, MD, MSCS, a pediatric rheumatologist and assistant professor of pediatrics at Children’s Hospital Colorado, Aurora, and colleagues performed an analysis of patients with granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) who were enrolled in the Vasculitis Clinical Research Consortium Longitudinal Studies from 2013 to 2021.

Patients with eosinophilic GPA (EGPA) were analyzed separately. Children and young adults with EGPA were combined because of the small sample size (n = 87).

The groups were sorted by the age they were diagnosed: under 18 years old, 18-40, 40-65, and older than 65.
 

More than 1,000 patients included

Dr. Bloom’s team analyzed data from 1,020 patients: 61 diagnosed as children, 240 as young adults, 560 as middle-aged adults, and 159 diagnosed as older adults. At all ages, about nine out of 10 patients were White.

They found 852 (84%) had GPA and 165 (16%) had MPA. The analysis also showed 893 (92%) of patients with ANCA results were ANCA positive: 637 (65%) with PR3-ANCA, 247 (25%) with MPO-ANCA, and 9 (1%) with both.

Differences between age groups included:

• Children experienced more subglottic stenosis and alveolar hemorrhage than adults with the condition.
• About half of patients diagnosed in childhood received both cyclophosphamide and rituximab. That rate decreased with increasing age of diagnosis to as low as 14% for those diagnosed in older adulthood. 
• More females than males in all age groups were diagnosed with AAV, but the difference was most pronounced when diagnosed in childhood, and female predominance declined as age increased.
• Older adults experienced more neurologic disease and less musculoskeletal and sinus involvement.

Additionally, for those diagnosed after age 65, after adjusting for disease length and whether they were taking cyclophosphamide and/or rituximab, the Vasculitis Damage Index (VDI) and ANCA Vasculitis Index of Damage (AVID) scores were higher than for those diagnosed in childhood.

“However, these differences are no longer significant when medication toxicity and comorbidity-related items are excluded. Thus, differences in the VDI and AVID scores are driven by non–disease-specific damage,” Dr. Bloom said.
 

Bringing children into the clinical discussion

Dr. Bloom said in an interview that many pediatric rheumatologists believe kids with vasculitis are like small adults and should be treated similarly, but she said the picture may be more complex than that.

For example, the findings that children have more subglottic stenosis and alveolar hemorrhage than adults “may warrant more aggressive therapy,” she said. Children also have different growth and psychosocial risk factors during their disease course and may live longer with the disease than those in older age groups.

“Our study helps to point out these differences and bring children into the discussion,” Dr. Bloom said. “It also recognizes that damage scores used in studies and care may not adequately assess disease across the lifespan, as they are largely influenced by items not specific to the disease but rather medication toxicity and comorbidities, such as osteoporosis, cataracts, and malignancy.”

Robert Spiera, MD, director of the Scleroderma, Vasculitis, and Myositis Center at Hospital for Special Surgery, New York, said in an interview that the work highlights interesting information about the fact that disease features are skewed differently in children – “in particular the higher likelihood of upper airway [subglottic] disease, and potentially severe lower airway disease [alveolar hemorrhage].”

However, from a practical standpoint, Dr. Spiera said, “I am not sure that this will change our clinical approach to different patients, but the differences in disease features and even the sex differences in terms of who are afflicted with GPA [more often children and more likely to be female] may offer insights into disease pathogenesis.”

Dr. Bloom received funding from the Vasculitis Clinical Research Consortium and Vasculitis Foundation to conduct this work as a VCRC-VF fellow. Several coauthors reported various conflicts of interest with pharmaceutical companies. Dr. Spiera declared no relevant financial relationships.

AT ACR 2022

PHILADELPHIA – The first consensus screening guidelines for patients with idiopathic inflammatory myopathy (IIM) provide recommendations on risk stratification for individuals, basic and enhanced screening protocols, and screening frequency.

The recommendations, issued by the International Myositis Assessment and Clinical Studies Group (IMACS), stratify cancer risk for individual patients into low, intermediate, or high categories based on the IIM disease subtype, autoantibody status, and clinical features, reported Alexander Oldroyd, PhD, MSc, MBChB of the University of Manchester, England.

Neil Osterweil/MDedge News

“There’s a big unmet need for cancer screening. One in four adults with myositis has cancer, either 3 years before or after a diagnosis of myositis. It’s one of the leading causes of death in these patients, and they’re overwhelmingly diagnosed at a late stage, so we need standardized approaches to get early diagnosis,” he said in an interview at the annual meeting of the American College of Rheumatology.

Sharon Kolasinski, MD, of the University of Pennsylvania in Philadelphia, said in an interview that the guideline is a welcome development for rheumatologists. Dr. Kolasinski moderated the session where Dr. Oldroyd described the guideline, but she was not involved in its formulation.

“I think that we all have wondered for a very long time: What is the optimal cancer screening for myositis patients? We all worry that the onset of their diseases is associated with a coincident cancer, or that they will develop it soon,” she said.

Dr. Oldroyd emphasized that all patients with myositis have elevated risk for cancer compared with the general population and that the guideline categories of low, intermediate, and high are relative only to patients with IIM.
 

International consensus

The data on which the recommendations are based come from a systematic review and meta-analysis by Dr. Oldroyd and colleagues of 69 studies on cancer risk factors and 9 on IIM-specific cancer screening.

The authors of that paper found that the dermatomyositis subtype, older age, male sex, dysphagia, cutaneous ulceration and antitranscriptional intermediary factor-1 gamma (anti-TIF1-gamma) positivity were associated with significantly increased risk of cancer.

In contrast, polymyositis and clinically amyopathic dermatomyositis subtypes, Raynaud’s phenomenon, interstitial lung disease, very high serum creatine kinase or lactate dehydrogenase levels, and positivity for anti-Jo1 or anti-EJ antibodies were associated with significantly reduced risk of cancer.

The consensus recommendations were developed with anonymous contributions from 75 expert participants in 22 countries, with additional input from 3 patient partners.
 

Do this

The guideline lists 18 recommendations, of which 13 are strong and 5 are conditional.

An example of a strong recommendation is number 3, based on a moderate level of evidences:

“All adult IIM patients, irrespective of cancer risk, should continue to participate in country/region-specific age and sex appropriate cancer screening programs,” the guideline recommends.

Patients with verified inclusion body myositis or juvenile-onset IIM do not, however, require routine screening for myositis-associated cancer, the guideline says (recommendations 1 and 2).

There are also recommendations that all adults with new-onset IIM be tested for myositis-specific and myositis-associated autoantibodies to assist in stratifying patients by risk category.

The guideline divides screening recommendations into basic and enhanced. The basic screening should include a comprehensive history and physical exam, complete blood count, liver functions tests, erythrocyte sedimentation rates/plasma viscosity, serum protein electrophoresis, urinalysis, and chest x-ray.

Adults with IIM who are determined to be at low risk for IIM-related cancer should have basic cancer screening at the time of IIM diagnosis. Adults with intermediate risk should undergo both basic and enhanced screening at the time of IIM diagnosis, and those with high risk should undergo enhanced screening at the time of myositis diagnosis, with basic screening annually for 3 years, the recommendations say.
 

Consider doing this

Conditional recommendations (“clinicians should consider ...”) include the use of PET/CT for adults at high risk for cancer when an underlying cancer has not been detected at the time of IIM diagnosis. They also include a single screening test for anti-TIF1-gamma positive dermatomyositis patients whose disease onset was after age 40 and who have at least one additional risk factor.

Also conditionally recommended are upper and lower gastrointestinal endoscopy for patients at high risk when an underlying cancer is not found at the time of IIM diagnosis, nasoendoscopy in geographical regions with elevated risk for nasopharyngeal cancers, and screening for all IIM patients with red-flag symptoms or clinical features of cancer, including unexplained weight loss, family history of cancer, smoking, unexplained fever, or night sweats.
 

Guided steps

“I think clinicians have a lot of questions such as, ‘well, what should I do, when should I do it?’ These are important clinical questions, and we need guidance about this. We need to balance comprehensiveness with cost-effectiveness, and we need expert opinion about what steps we should take now and which should we take later,” Dr. Kolasinski said.

The guideline development process was supported by the University of Manchester, IMACS, National Institute for Health Research (United Kingdom), National Institutes of Health, National Health Service Northern Care Alliance, The Myositis Association, Myositis UK, University of Pittsburgh, Versus Arthritis, and the Center for Musculoskeletal Research. Dr. Oldroyd and Dr. Kolasinski reported having no relevant conflicts of interest.

Exercise tops the list of 28 recommendations in a guideline for integrative interventions in patients with rheumatoid arthritis developed by the American College of Rheumatology.

The guideline is specific to RA and presents integrative interventions to accompany treatment with disease-modifying antirheumatic drugs (DMARDs), according to a summary statement issued by the ACR. The summary was approved by the ACR Board of Directors on Oct. 31, and the recommendations are part of a manuscript that will be submitted for publication in both Arthritis & Rheumatology and Arthritis Care & Research.

Consistent engagement in exercise earned the only strong recommendation; the other 27 were conditional. In the exercise category, the authors offered conditional recommendations for aerobic exercise, aquatic exercise, resistance exercise, and mind-body exercise.

Three recommendations focused on diet. Notably, the recommended diet is Mediterranean style. Two other recommendations were specifically against any other formal diet and against the use of dietary supplements. “The conditional recommendation for adhering to a Mediterranean-style diet, but not other formally defined diets, to improve RA-specific outcomes may be surprising to some clinicians,” said Bryant R. England, MD, PhD, of the University of Nebraska Medical Center, Omaha, and one of the guideline’s coprincipal investigators, in a press release. “The voting panel acknowledged, however, that other health indications may exist for alternative diet and dietary supplements, which makes it crucial for clinicians and patients to engage in shared decision-making,” Dr. England said.

Nearly half of the 28 recommendations (13) focused on rehabilitation, but all were conditional. These included comprehensive occupational and physical therapy and hand therapy, as well as the use of splinting, orthoses, compression, bracing, and taping of affected areas. Other conditional recommendations supported the use of joint protection techniques, assistive devices, adaptive equipment, and/or environmental adaptations. The authors also included a conditional recommendation for vocational rehabilitation and work-site evaluations and/or modifications.

A category of additional integrative interventions included recommendations against both electrotherapy and chiropractic care. However, conditional recommendations were positive for acupuncture, massage therapy, and thermal modalities. Conditional recommendations also supported cognitive-behavioral therapy and/or mind-body strategies, and a standardized self-management program.

The guideline was developed by an interprofessional voting panel of 20 individuals with expertise in epidemiology, exercise physiology, GRADE (Grading of Recommendations Assessment, Development, and Evaluation) methodology, integrative medicine, nursing, nutrition, occupational therapy, physical therapy, rheumatology, and social work, as well as three individuals who have RA. The panel developed questions, conducted a literature review, and used the GRADE approach to rate the certainty of evidence.

“These recommendations are specific to RA management, understanding that other medical indications and general health benefits may exist for many of these interventions,” the authors write in the summary statement.

The range of interventions shows both the importance of an interprofessional team–based approach to RA management and the need to engage patients in shared decision-making, they said.

The incidence of dementia in patients with rheumatoid arthritis who took either a biologic disease-modifying antirheumatic drug (bDMARD) or targeted synthetic DMARD (tsDMARD) was significantly lower than the rate observed in patients who take only a conventional synthetic DMARD (csDMARD) in a national database study.

The work builds on previous research indicating a higher risk of Alzheimer’s disease and related dementias in people with RA. While joint pain and swelling are the cardinal symptoms of RA, its systemic inflammation leads to multiple systemic manifestations, offering biologically plausible links with cognitive decline. In addition, patients with RA have high prevalence of cardiovascular disease, diabetes, depression, disability, and physical inactivity, all of which are risk factors for dementia.

Chronic neuroinflammation secondary to either intrinsic or systemic stimuli is thought to play a key role in dementia development, especially Alzheimer’s dementia (AD). Research showing a role of tumor necrosis factor–alpha (TNF-alpha) in the development of dementia has piqued interest in a potential protective effect of TNF inhibitors. “TNF-alpha is thought to have an important role in different stages of the pathophysiology and disease progression of Alzheimer’s disease,” study first author Sebastian E. Sattui, MD, assistant professor of medicine at the University of Pittsburgh and director of the University of Pittsburgh Vasculitis Center, said in an interview. “Animal models have shown that TNF inhibition reduces microgliosis, neuronal loss, and tau phosphorylation. Cognitive improvement has been seen in two trials with Alzheimer’s disease patients, but were not in rheumatoid arthritis patients.”

In the newest study, published online in Seminars in Arthritis and Rheumatism, Dr. Sattui and colleagues suggest that a lower risk for dementia seen with bDMARDs and tsDMARDs may be attributable to an overall greater decrease in inflammation rather than any mechanism of action specific to these drugs.

In the study of Centers for Medicare & Medicaid Services claims during 2006-2017 for 141,326 adult patients with RA, the crude incident rates were 2.0 per 100 person-years (95% confidence interval, 1.9-2.1) for patients on csDMARDs and 1.3 (95% CI, 1.2-1.4) for patients on any b/tsDMARD. There were 3,794 cases of incident dementia during follow-up among 233,271 initiations of any DMARD. The adjusted risk for dementia among users of bDMARDs or tsDMARDs was 19% lower than the adjusted risk for patients on csDMARDs (hazard ratio, 0.81; 95% CI, 0.76-0.87). No significant differences were found between classes of bDMARDs or tsDMARDs.

Dr. Sattui and coauthors’ investigation included adults aged at least 40 years with two RA diagnoses by a rheumatologist more than 7 and less than 365 days apart. Those with prior dementia diagnoses were excluded. Their analysis found the risk of incident dementia to be comparable between patients receiving TNF inhibitors (HR, 0.86; 95% CI, 0.80-0.93), non-TNFi bDMARDs (HR, 0.76; 95% CI, 0.70-0.83), and tsDMARDs (HR, 0.69; 95% CI, 0.53-0.90), with csDMARDs as the referent. A second subgroup analysis looking at patients with prior methotrexate use who were taking bDMARDs or tsDMARDs revealed similar decreases in risk of incident dementia, compared with patients taking bDMARDs or tsDMARDs along with methotrexate at baseline.

“NSAIDs and glucocorticoids have been studied in RCTs [randomized, controlled trials],” Dr. Sattui said in the interview. “Despite initial observational data that showed some signal for improvement, no benefit was observed in either of the RCTs. Other agents with possible anti-inflammatory effects and more benign profiles, such as curcumin, are being studied. There are also ongoing trials looking into the use of JAK [Janus kinase] inhibitors or [interleukin]-1 inhibition in dementia.”

He added: “There is a need to better study the association between cognition and disease activity, as well as treat-to-target strategies, prospectively in patients with RA. It is important to also acknowledge that any of these findings might be just specific for RA, so extrapolation to non-RA individuals might be limited.”

In commenting on the findings of the study, Rishi J. Desai, PhD, assistant professor of medicine in the division of pharmacoepidemiology and pharmacoeconomics at Brigham and Women’s Hospital, Boston, said that “superior inflammation control with biologics or targeted DMARDs is an interesting hypothesis explaining the observed findings. It merits further investigation and replication in diverse populations.” He added: “It should be noted that a key challenge in evaluating this hypothesis using insurance claims data is unavailability of some important factors such as socioeconomic status and patient frailty. These may be driving treatment selection between conventional DMARDs, which are cheaper with more benign adverse-event profiles, and biologic or targeted DMARDs, which are more expensive with a less favorable adverse-event profile.”
 

Prior research

Several studies have investigated the effect of DMARDs, including bDMARDs like tumor necrosis factor inhibitors, on incident dementia in patients with RA.

Among this research is a study by Dr. Desai and colleagues that looked at comparative risk of AD and related dementia in 22,569 Medicare beneficiaries receiving tofacitinib (a JAK inhibitor), tocilizumab (an IL-6 inhibitor), or TNF inhibitors in comparison with abatacept (a T-cell activation inhibitor). No differentiating risk associations were found in this cohort study.

Other past studies include:

• A study comparing about 21,000 patients with RA and a non-RA cohort of about 62,000 found a 37% reduction in dementia development among RA patients receiving DMARDs. The effect was dose dependent, greater with high cumulative dosages, and was found in both men and women and in subgroups younger and older than 65 years.
• A retrospective study of electronic health records from 56 million adult patients identified a subset of patients with RA, psoriasis, ankylosing spondylitis, ulcerative colitis, or Crohn’s disease in whom systemic inflammation increased risk for AD through a mechanism involving TNF. The risk for AD in patients was lowered by treatment with etanercept, adalimumab, infliximab, or methotrexate, with larger reductions observed in younger patients than in older patients receiving TNF blockers.
• A propensity score–matched retrospective cohort study in 2,510 U.S. veterans with RA found that use of a TNF inhibitor reduced the risk of dementia by 36%, compared with control patients (HR, 0.64; 95% CI, 0.52-0.80), and the effect was consistent over 5-20 years post RA diagnosis.
• In a retrospective, multinational, matched, case-control study of patients older than 50 years with RA, prior methotrexate use was associated with lower dementia risk (OR, 0.71; 95% CI, 0.52-0.98). Use of methotrexate longer than 4 years demonstrated the lowest dementia risk (odds ratio, 0.37; 95% CI, 0.17-0.79).

These past studies, Dr. Sattui and colleagues pointed out, have multiple shortcomings, including case-control design, different definitions of exposure or outcomes, and inadequate control of confounders, underscoring the need for more rigorous studies.

Several authors of the CMS claims study disclosed research support, grants, and consulting fees from pharmaceutical companies. The research was supported by a grant from the National Institutes of Health. Dr. Desai disclosed that he has received funding from the National Institute on Aging for drug repurposing studies of dementia.

Therapeutic drug monitoring allowed patients with rheumatoid arthritis, psoriatic arthritis, and spondyloarthritis to reduce their dosage of tumor necrosis factor–alpha (TNF) inhibitors, based on data from 239 individuals.

Use of TNF-alpha inhibitors improves treatment response for many arthritis patients but dosage is rarely adjusted on an individual level, which may lead to unnecessary overdosing in some patients, Mogens Pfeiffer-Jensen, MD, of Aarhus (Denmark) University Hospital, and colleagues wrote.

Data from previous studies suggest that therapeutic drug monitoring (TDM) based on serum trough levels may allow for dose optimization and dose reduction in inflammatory bowel disease patients, but data in patients with arthritis are lacking, they wrote.

In a study published in the Scandinavian Journal of Rheumatology, the researchers recruited 99 patients with RA, 48 with psoriatic arthritis (PsA), and 92 with spondyloarthritis (SpA). The participants were randomized to standard care or standard care plus TDM. Serum trough levels were assessed at baseline and at every 4 months, and prescription changes or drug switches were implemented based on these levels. At baseline, 81 patients were being treated with infliximab (Remicade and biosimilars), 79 with etanercept (Enbrel), and 79 with adalimumab (Humira).

The primary endpoint was reduced drug prescription after 48 weeks.

Overall, TDM significantly reduced prescription of infliximab by 12% (P = .001) and prescription of etanercept by 15% (P = .01), compared with standard care. TDM also prolonged the interdosing intervals of etanercept by 235% (P = .02) and of adalimumab by 28% (P = .04), compared with standard care.

TDM patients taking infliximab had more frequent dose reduction and less frequent dose increases during and after the study when compared with patients who stayed with standard care; similar trends were seen with adalimumab. TDM also accelerated the switch to other biologics for patients on all three medications.

No significant differences occurred in adverse events or hospitalizations between the TDM and standard care patients.

Clinical composite scores (Disease Activity Score based on 28 joints with C-reactive protein) were reduced in patients with RA and PsA who were taking adalimumab and randomized to TDM, but no other clinical outcome differences were noted. Scores on the Health Assessment Questionnaire and global Visual Analog Scale for pain were significantly lower in patients in the TDM group who were taking infliximab and adalimumab, “indicating equally or superior sustained remission across diagnoses,” the researchers emphasized.

The findings were limited by several factors, including the variations in pathophysiology and open-label design. “However, since the TDM was based on an objective serum value and decision procedures were clear, we do not consider the potential of unconscious bias to outweigh the benefits of dose-changing abilities,” they wrote.

The researchers expressed surprise that the reduced use of TNF-alpha inhibitors did not significantly reduce adverse events or serious adverse events, compared with standard care, but they proposed that standard of care may have taken adverse events into account, because all patients had received prescriptions at least 3 months before the study.

As for clinical implications, the current costs of the biochemical assays necessary for TDM may be a barrier to implementing TDM as a standard part of daily clinical practice, the researchers added. However, the study was strengthened by the inclusion of patients with RA, PsA, and SpA, and is the first known to include patients receiving etanercept or adalimumab in an examination of TDM.

“Our data support TDM based solely on serum trough levels in [TNF-alpha inhibitors] with different pharmacokinetics as a future key player in personalized medicine for chronic rheumatoid diseases treated with biologics,” they concluded.

The study was supported by Spydspidspuljen, Region Midt, Denmark, and Department of Rheumatology, Aarhus University Hospital. The researchers had no financial conflicts to disclose. 

Therapeutic drug monitoring allowed patients with rheumatoid arthritis, psoriatic arthritis, and spondyloarthritis to reduce their dosage of tumor necrosis factor–alpha (TNF) inhibitors, based on data from 239 individuals.

Use of TNF-alpha inhibitors improves treatment response for many arthritis patients but dosage is rarely adjusted on an individual level, which may lead to unnecessary overdosing in some patients, Mogens Pfeiffer-Jensen, MD, of Aarhus (Denmark) University Hospital, and colleagues wrote.

Data from previous studies suggest that therapeutic drug monitoring (TDM) based on serum trough levels may allow for dose optimization and dose reduction in inflammatory bowel disease patients, but data in patients with arthritis are lacking, they wrote.

In a study published in the Scandinavian Journal of Rheumatology, the researchers recruited 99 patients with RA, 48 with psoriatic arthritis (PsA), and 92 with spondyloarthritis (SpA). The participants were randomized to standard care or standard care plus TDM. Serum trough levels were assessed at baseline and at every 4 months, and prescription changes or drug switches were implemented based on these levels. At baseline, 81 patients were being treated with infliximab (Remicade and biosimilars), 79 with etanercept (Enbrel), and 79 with adalimumab (Humira).

The primary endpoint was reduced drug prescription after 48 weeks.

Overall, TDM significantly reduced prescription of infliximab by 12% (P = .001) and prescription of etanercept by 15% (P = .01), compared with standard care. TDM also prolonged the interdosing intervals of etanercept by 235% (P = .02) and of adalimumab by 28% (P = .04), compared with standard care.

TDM patients taking infliximab had more frequent dose reduction and less frequent dose increases during and after the study when compared with patients who stayed with standard care; similar trends were seen with adalimumab. TDM also accelerated the switch to other biologics for patients on all three medications.

No significant differences occurred in adverse events or hospitalizations between the TDM and standard care patients.
