Effectiveness of golimumab intensification in ulcerative colitis: A multicentric prospective study


Introduction: Loss of response to golimumab occurs in nearly 40% of patients with ulcerative colitis (UC). Unlike others anti-TNF, no study has reported a correlation between serum golimumab level and response to drug intensification. The objective of this study was to evaluate the effectiveness and safety of golimumab intensification and to identify the best threshold of serum golimumab before drug intensification predictive of response. Patients and methods: We included all consecutive patients with active UC with loss of response to golimumab in a prospective multicentric cohort study. Patients with loss of response at 50 mg q4 weeks (W) and 100 mg q4W underwent therapeutic intensification at 100 mg q4W and 100 mg q2W, respectively. Effectiveness and safety were assessed between Weeks 2 and 4 (visit 2) and between Weeks 4 and 8 (visit 3) after intensification. Serum level and anti-golimumab antibodies were evaluated at each medical visit (Lisa Tracker, Theradiag France). Results: A total of 47 UC patients (Female, 50%; median age, 39 years (IQR, 27-52)) treated with golimumab for a median of 20.4 weeks (IQR, 10.7-38.3) were included. The median partial Mayo score was 6 (IQR, 5-7), and the median endoscopic Mayo score was 3 (IQR, 2-3). The median golimumab serum level before intensification was 2.23 μg/mL (IQR, 1.02-3.96) and only one patient (2.1%) had anti-drug antibodies. At Visit 2 (Week 2-4), 40% patients experienced clinical response, 10% clinical remission, 33% endoscopic response and 23% endoscopic remission. At Visit 3 (Week 4-8), 44% of patients had clinical response, 22% of patients had clinical remission, 45% of patients had endoscopic response, and 41% of patients had endoscopic remission. The median golimumab levels before intensification do not differ between responders and non-responders (2.13 μg/ml (0.76-2.76) and 3.37 μg/ml (IQR, 1.08-4.67), respectively; p = 0.14) assessed at Visit 3. Golimumab intensification to 100 mg q4W (vs q2W) (OR 1.98, 95% CI [1.06-3.70]; p = 0.032) was significantly associated with clinical remission at Visit 3. Serum drug level at baseline or the presence of antidrug antibodies were not associated with clinical or endoscopic remission/response. Two serious adverse events (one infection and one UC flare) were reported during the 24-week follow-up. Conclusion: In this prospective multicentric study, half of patients recaptured response following golimumab intensification in UC. Therapeutic drug monitoring did not predict response after optimisation of golimumab.
