Real-world setting serves as starting point
The RETRO study is unique in that it tried to reflect a real-life setting by enrolling patients on baseline treatment with combinations of conventional synthetic DMARDs and biologic DMARDs seen in clinical practice rather than only patients taking biologic DMARDs – primarily TNF inhibitors – as done in previous studies of tapering and stopping DMARDs, wrote Catherine L. Hill, MD, of the University of Adelaide (Australia), in an accompanying editorial. It is also “used a simple, pragmatic one-size-fits-all treatment-tapering strategy,” she wrote.
However, she emphasized that answers are needed to questions about what relapse rates are acceptable, what duration of treatment-free time is ideal, and whether benefits to the patient outweigh risks.
Dr. Hill also highlighted the issue of identifying patients who are appropriate candidates for tapering or withdrawal. Stricter remission criteria may not be feasible in routine practice, and so “the development of algorithms to guide patient selection is likely to be the most practical way forward for clinicians and patients,” she wrote.
“Contemplation of treatment tapering or discontinuation in some patients with rheumatoid arthritis is remarkable and a measure of how far treatments have advanced,” Dr. Hill wrote. “However, further work to address outstanding questions on who should taper and how best to do it is still required,” she concluded.
The study received no outside funding. Lead author Dr. Tascilar disclosed lecture fees from Gilead and Union Chimique Belge; several coauthors disclosed relationships with multiple companies outside the current study. Dr. Hill had no financial conflicts to disclose.
