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.

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. PURSUIT-M (NCT00488631; EudraCT, 2006-003399-37).
