A retrospective observational study of effectiveness of sequential biologic and targeted synthetic DMARDs in psoriatic arthritis in the UK

Gollins et al. reported that within this cohort, the Psoriatic arthritis response criteria (PsARC) response to 4th+ lines of b/tsDMARD was not significantly reduced compared with 2nd/3rd line in participants who had failed at least 3 b/tsDMARDs. Authors evaluated the primary clinical response to sequential lines of b/tsDMARD therapy in PsA, focusing on the effectiveness of later line treatments.

The SEQUENCE study provides the first evidence of PsARC response in a UK cohort in lines of b/tsDMARD beyond 3rd line. These results indicates that patients in a UK cohort can continue to have a meaningful response to later lines of treatment. Further prospective representative studies are required to better understand the effectiveness response in this population of difficult-to-treat patient.
