Abstract

To report long-term efficacy of certolizumab pegol (CZP) treatment with and without concomitant DMARDs in patients with psoriatic arthritis (PsA). RAPID-PsA (NCT01087788) was double-blind and placebo-controlled to week 24, dose-blind to week 48, and open-label to week 216. Patients had active PsA with >/= 1 failed DMARD. At baseline, patients were randomized 1:1:1 to CZP 200 mg every 2 weeks: CZP 400 mg every 4 weeks: placebo. CZP-randomized patients continued their dose into open-label. Observed case efficacy data are reported to week 216 for week 0 CZP-randomized patients (dose combined) with and without baseline DMARD use (DMARD+/DMARD-). Dactylitis (tenderness and >/= 10% difference in swelling between affected and opposite digits) and enthesitis were measured using Leeds Dactylitis Index (LDI) and Leeds Enthesitis Index (LEI). 273/409 randomized patients received CZP from baseline: 199/273 (72.9%) DMARD+ and 74/273 (27.1%) DMARD- patients. 141/199 (70.9%) DMARD+ and 42/74 (56.8%) DMARD- patients completed Week 216. DMARD+ (79.7%) and 83.3% of DMARD- patients achieved ACR20 response at week 216; 79.2 and 78.1% achieved 75% improvement from baseline in Psoriasis Area and Severity Index (PASI75). High proportions of DMARD+/DMARD- patients with extra-articular manifestations at baseline reported total resolution at week 216; dactylitis 91.4% of DMARD+ and 93.3% of DMARD- patients, enthesitis 74.4% of DMARD+ and 87.5% of DMARD- patients. Long-term improvements in PsA symptoms were observed with CZP monotherapy or concomitant DMARDs, across important psoriatic disease domains, including joint disease, psoriasis, nail disease, dactylitis, and enthesitis. TRIAL REGISTRATION: NCT01087788.
