The objective of this study was to evaluate biological disease-modifying anti-rheumatic drugs (bDMARDs) survival in several therapy courses of patients affected by psoriatic arthritis (PsA) and to compare tumor necrosis factor inhibitors (TNFi) and non-TNFi retention rates. A total of 241 bDMARD therapy courses (155 TNFi drugs, 65 anti-interleukin (IL)-17 drugs, and 21 anti-IL12/23) were analyzed. Bivariate analyses were performed to assess the presence of demographic and clinical features, as well as comorbidities, associated with bDMARD discontinuation in TNFi and non-TNFi groups. In the bivariate analyses of TNFi and non-TNFi groups, we found a lower age at the start of TNFi therapy in the former group [46 years, interquartile range (IQR) 45-54 vs 50.5 years, IQR 42-61; p=0.004] as well as a lower proportion of patients with skin psoriasis (65.8% vs 88.4%; p<0.001). Survival analysis showed no significant differences between TNFi and non-TNFi groups. Cox regression found fibromyalgia as a predictor of drug failure [hazard ratio (HR) 3.40, confidence interval (CI) 1.92-6.03; p<0.001] and first-line bDMARDs as a protective factor (HR 0.46, CI 0.25-0.88; p=0.019). Lastly, among TNFi courses, fibromyalgia was associated with drug suspension (HR 6.52, CI 3.16-13.46; p<0.001), while only a trend of significance for skin psoriasis as a risk factor for drug failure was shown (HR 2.38, CI 1.00-5.66, p=0.05). This study provides information about clinical and demographic factors associated with retention rates of bDMARDs from a real-life, single-center cohort of PsA patients.
