Effectiveness of sequential lines of biologic and targeted small-molecule drugs in psoriatic arthritis: a systematic review.
Rheumatology (Oxford, England)(2024)
Abstract
OBJECTIVE:To assess current evidence for effectiveness of sequential lines of biologic and targeted small-molecule disease-modifying anti-rheumatic drugs (b/tsDMARDs) when used beyond first-line for psoriatic arthritis (PsA).
METHODS:A systematic search of the literature (Medline, Embase, bibliographic searches) was undertaken (October and December 2022) to find studies meeting the criteria of assessing effectiveness of b/tsDMARDs beyond first-line in adults with PsA (PROSPERO CRD42022365298). Risk of bias assessment was undertaken (ROBINS-I/Cochrane RoB2).
RESULTS:Of 2666 abstracts identified and following a full text review of 177 psoriatic disease studies, 12 manuscripts and two abstracts were eligible. Of the 12 manuscripts, 11 were observational and one was a sub-analysis of a RCT (n = 16 081: average age 49.5 years, female 53.3%). Two abstracts (n = 7186) were included. All studies comparing first- and second-line (three studies) found a reduced response in second-line. On average, DAPSA remission (most reported outcome, eight studies) was achieved in 26%, 19% and 10% first-, second- and third-line TNFi, and 22%, 13% and 11% first-, second- and third-line other bDMARDs, respectively. Responses varied to third-line bDMARDs; four studies found comparable second- and third-line responses, five studies found diminishing responses in sequential lines.
CONCLUSION:Predominantly observational studies, inherently at high risk of bias, indicate bDMARDs can be effective to third-line in PsA, but that response is reduced after first line. There is very limited data for more advanced lines of b/tsDMARD. Prospective studies are required to better understand clinical response to advanced lines of treatment in PsA.
