Abstract
[Abstract]
Introduction: COMPACT, a non-interventional study, evaluated the persistence, effectiveness, safety and patient-reported outcomes (PROs) in patients with rheumatoid arthritis (RA), axial-spondyloarthritis (axSpA) or psoriatic arthritis (PsA) treated with SDZ ETN (etanercept [ETN] biosimilar) in Europe and Canada.
Methods: Patients (aged ≥ 18 years) who have been treated with SDZ ETN were categorised on the basis of prior treatment status (groups A-D): patients in clinical remission or with low disease activity under treatment with reference ETN or biosimilar ETN and switched to SDZ ETN; patients who received non-ETN targeted therapies and switched to SDZ ETN; biologic-naïve patients who started SDZ ETN after conventional therapy failure; or disease-modifying anti-rheumatic drug (DMARD)-naïve patients with RA considered suitable for treatment initiation with a biologic and started on treatment with SDZ ETN. The primary endpoint was drug persistence, defined as time from study enrolment until discontinuation of SDZ ETN treatment.
Results: Of the 1466 patients recruited, 844 (57.6%) had RA, 334 (22.8%) had axSpA and 288 (19.6%) had PsA. Patients had an ongoing SDZ ETN treatment at the time of enrolment for an observed average of 138 days (range 1-841); 22.7% of patients discontinued SDZ ETN through 12 months of study observation. Overall, all the patients receiving SDZ ETN showed good treatment persistence at 12 months with discontinuation rates of 15.2%, 25.7% and 27.8% in groups A, B and C, respectively. Across all patient groups, no major differences were observed in the disease activity and PRO scores between baseline and month 12. Injection-site reactions were low across the treatment groups.
Conclusion: These results support the effectiveness and safety of SDZ ETN treatment in patients with RA, axSpA or PsA in real-life conditions. The treatment persistence rates observed were consistent with previously published reports of patients treated with reference or other biosimilar ETN. No new safety signals were identified.
