Background The purpose of PsABio (ClinicalTrials.gov Id: NCT02627768) is to evaluate the efficacy, tolerability and persistence of TNF inhibitors (TNFi) and ustekinumab (UST) for patients with psoriatic arthritis (PsA) starting 1st, 2nd or 3rd line biologic disease-modifying antirheumatic drugs (bDMARDs) in real-world routine care. Objectives Here we present the first interim follow-up data on joint-related outcomes. Methods Of 278 UST- and 285 TNFi-treated patients consecutively enrolled between Dec 2015 and ,Aug 2017 152 and 151, respectively, had data available at 6 months for their initial line of treatment. Joint-related outcomes, as observed data, were compared between baseline and 6 months within the treatment cohorts. Results Among all enrolled patients, 7.6% of UST- and 10.2% of TNFi-treated patients stopped or switched to another bDMARD before the 6 month timepoint. For those with 6 month data for their initial bDMARD, UST was used as the first-line bDMARD in 40.1%, as 2nd in 35.5%, and as 3rd in 24.3% of patients; these numbers were 64.2%, 28.5%, and 7.3%, respectively, for TNFi. DAS28 scores improved significantly at 6 months from mean baseline values of 4.3 (SD 1.2) and 4.3 (SD 1.2) for UST and TNFi, respectively, by means of −1.3 (95% CI: −1.6, −1.0) and −1.3 (95% CI: −1.6, −1.1). Significant improvements were seen in both cohorts across all treatment lines (table 1) and subtypes of PsA (data not shown). Minimal disease activity (MDA) was achieved at 6 months for 28.8% of UST- and 29.7% of TNFi-treated patients. CDAI results similarly and significantly improved. For the DAPSA, equally, statistically significant improvements were seen: mean −18.4 (95% CI: −22.2, −14.5) and −19.5 (95% CI: −22.5, −16.5) for UST and TNFi, respectively, with 12.2% and 15.7% reaching DAPSA remission and 37.8% and 37.1% reaching low disease activity. cDAPSA showed similar improvement. For details on components of the DAS28 and of the DAPSA, see table 1. Axial joint involvement was significantly improved with reductions in BASDAI and ASDAS.Abstract AB0928 – Table 1 Baseline and follow-up data for joint-related outcomes for patients having reached 6 months on their initial bDMARD. Values are mean (SD) or mean (95% CI) if not otherwise indicated. na, not applicable. aAmong all patients with available data at baseline and month 6 (UST, n=128; TNFi, n=114). bAmong all patients with available data at baseline and month 6 (UST, n=82; TNFi, n=87). Conclusions Both UST- and TNFi-treated patients showed statistically significant and considerable improvements in joint-related measures after 6 months in a real-world setting, irrespective of whether first or further line of treatment.
