Abstract

Objectives

The aim of this multicenter, retrospective study was to clarify the retention rates of sarilumab (SAR), baricitinib (BAR), and tofacitinib (TOF) in patients with rheumatoid arthritis (RA).

Methods

Patients treated with either SAR (n = 62), BAR (n = 166), or TOF (n = 185) (females, 80.9%; age, 61.0 years; disease duration, 11.1 years; rheumatoid factor positivity, 84.4%; Disease Activity Score in 28 joints using erythrocyte sedimentation rate, 4.3; concomitant prednisolone dose, 5.3 mg/day [47.0%] and methotrexate dose, 8.8 mg/week [58.4%]; biologics- or Janus kinase inhibitors-switched cases 78.4%) were included. The reasons for drug discontinuation were classified into 4 major categories (lack of effectiveness, toxic adverse events, non-toxic reasons, and remission) by each attending physician. The drug retention rate was estimated at 18 months using the Kaplan–Meier method and adjusted for potential confounders by Cox proportional hazards modeling.

Results

The discontinuation rates of SAR, BAR, and TOF for the corresponding reasons were as follows, respectively: lack of effectiveness (15.7%, 15.6%, and 21.5%; P = 0.84), toxic adverse events (15.8%, 12.1%, and 12.3%; P = 0.35), non-toxic reasons (10.9%, 7.7%, and 6.8%; P = 0.35), and remission (0.0%, 2.8%, and 0.0%; P = 1.0). The overall retention rates excluding non-toxic reasons and remission were as follows: 68.8% for SAR, 72.5% for BAR, and 66.7% for TOF (P = 0.54).

Conclusions

After adjustment by potent confounders, SAR, BAR, and TOF showed similar discontinuation rates due to lack of effectiveness and toxic adverse events.
Key Points
• This is the first retrospective multicenter study that aimed to clarify the retention rates and reasons for discontinuation of SAR, BAR, and TOF in patients with RA.

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
