Low Occurrence of Colectomy With Long-Term (up to 4 Years) Golimumab Treatment in Patients With Moderate-to-Severe Active Ulcerative Colitis: Data From the PURSUIT Maintenance and Long-Term Extension Studies

Abstract

Abstract Background This analysis evaluated the incidence of all-cause colectomies (total or partial) among patients with moderate-to-severe active ulcerative colitis (UC) in the golimumab (GLM) Program of Ulcerative Colitis Utilizing an Investigational Treatment (PURSUIT)-maintenance (-M) and long-term extension (-LTE) studies. Methods Eligible PURSUIT-M trial participants completed a 6-week GLM induction trial without requiring colectomy. Responders to GLM induction were randomized 1:1:1 to GLM 50 mg, GLM 100 mg, or placebo (PBO) maintenance for up to 1 year, administered every 4 weeks (q4w). Nonresponders to GLM or PBO induction received GLM 100 mg; responders to PBO induction received PBO (each administered q4w for up to 1 year). Participants who completed PURSUIT-M were eligible to continue their treatment in the 3-year PURSUIT-LTE study. Results A total of 60 (4.9%) colectomies were reported among the 1228 patients who enrolled in the 1-year PURSUIT-M study, which included 672 participants who continued into the 3-year PURSUIT-LTE LTE study (of which 666 were treated). The colectomy rate during the 3-year extension was lower than that observed during the maintenance phase of the study (9/666 [1.4%] compared to 51/1228 [4.2%]). The majority (43/60 [71.7%]) of the reported colectomies occurred in patients who had not responded to induction therapy and who tended to have had more severe disease characteristics at baseline. Conclusions This retrospective evaluation of colectomy data from the PURSUIT-M and -LTE studies in patients with moderate-to-severe active UC demonstrated a low (<5%) occurrence of colectomy with long-term (up to 4 years) GLM treatment.
