The study aimed to evaluate the real-world effectiveness of adalimumab (ADA) in UC and to identify predictors ofremission to ADA. Methods This cohort study used data from the ENEIDAregistry. Clinical response, clinical remission, endoscopicremission, adverse events (AE), colectomy, and hospitalisations were evaluated; baseline characteristics and biological parameters were compared to determine predictors of response. Results We included 263 patients (87 naı¨ve and 176 previously exposed to anti-tumour necrosis factor alpha, TNF). After 12 weeks, clinical response, clinical remission, and endoscopic remission rates were 51, 26, and 14 %, respectively. The naı¨ve group demonstrated betterresponse to treatment than the anti-TNF-exposed group at short-term. Clinical and endoscopic remission within 1 year of treatment was better in the naı¨ve group (65 vs. 49 and 50 vs. 35 %, respectively). The rates of AE, doseescalation, hospitalisations, and colectomy during the first year were higher in anti-TNF-exposed patients (40, 43, and 27 % vs. 26, 21, and 11 %, respectively). Patients withprimary failure and intolerance to the first anti-TNF and severe disease were associated with worse clinical response. Primary non-response to prior anti-TNF treatment and severe disease were predictive of poorer clinical remission. Low levels of C-reactive protein (CRP) and faecal calprotectin (FC) at baseline were predictors of clinical remission.Conclusions In clinical practice, ADA was effective in UC, especially in anti-TNF naı¨ve patients. FC and CRP could be predictors of treatment effectiveness.
