Background

Golimumab is effective in anti-TNF naïve patients with moderate-to-severe ulcerative colitis (UC). There are no data regarding the efficacy of golimumab in anti-TNF experienced UC patients. The aim of this study was to assess the short- and long-term outcomes of golimumab in UC patients according to prior anti-TNF use.

Methods

Retrospective multicentre cohort study evaluating all UC patients who received at least 2 golimumab induction doses at weeks 0 and 2. We compared the outcomes of the cohorts of anti-TNF experienced patients vs anti-TNF naïve patients. Post-induction short-term clinical response and remission were evaluated based on a partial Mayo score (PMS). In the long-term, the response and remission rates and the cumulative probabilities of golimumab failure-free survival and colectomy-free survival were calculated.

Results

From September 2012 to August 2015, 142 UC patients were evaluated. Of these, 85 (60%) had previous anti-TNF use (28 infliximab, 5 adalimumab and 52 both). Ninety-seven (68%) achieved short-term clinical response, of these 45 (32%) entered into remission. Mean PMS was 6 (range 3–9; standard deviation [SD] 1) at baseline and 3 (range 0–9; SD 3) at week 8 (p < 0.001). Clinical response and remission rates were significantly lower in the anti-TNF experienced patients compared with anti-TNF naïve patients (p = 0.03 and p = 0.01, respectively). After a median follow-up of 10 months (IQR 6–14), 67 patients (47%) maintained clinical response. Of these, 49 (35%) were in corticosteroid-free remission. Further, 33 anti-TNF experienced patients (39%) vs 34 anti-TNF naïve patients (60%) maintained response (p = 0.15). At last follow-up, 60 patients (42%) had golimumab failure. Anti-TNF experienced patients had a numerically higher adjusted rate of golimumab failure compared with anti-TNF-naïve patients (HR 1.4; 95% CI 0.82–.5; p = 0.22). Fifteen patients (11%) needed colectomy. Median time to colectomy was 4 months (IQR 29–). Anti-TNF experienced patients had a significantly higher adjusted rate of colectomy (HR 7.6; 95%CI 1.1–58.7; p = 0.02). Thirty-three patients (23%) required golimumab dose escalation. The median time to escalation was 5 months (IQR 3–9). Short-term response was identified as a predictor of golimumab failure-free survival (HR 0.2; 95% CI 0.12–0.34; p < 0.001) and colectomy-free survival (HR 0.16; 95% CI 0.05–.051; p = 0.002).

Conclusion

In this real-life cohort of UC patients treated with golimumab, 47% of patients maintained clinical response, and 89% of patients avoided colectomy. Although anti-TNF naïve patients had better outcomes, golimumab was also effective in anti-TNF experienced patients, with 62% having short-term clinical response, 39% maintaining clinical response, and 84% avoiding colectomy.
