A randomized phase 2 study of the 5-HT4 receptor agonist felcisetrag for postoperative gastrointestinal dysfunction after bowel surgery

Résumé fourni par la source

Background Felcisetrag (5-hydroxytryptamine-4 receptor [5-HT 4 ] agonist) is under investigation as prophylaxis or active treatment for accelerating resolution of gastrointestinal function post-surgery. Methods Phase 2, randomized, placebo-controlled, parallel five-arm, double-blind, multicenter study (NCT03827655) in 209 adults undergoing open or laparoscopic-assisted bowel surgery. Patients received intravenous placebo, felcisetrag 0.1mg/100mL or 0.5mg/100mL pre-surgery only, or pre-surgery and daily post-surgery until return of gastrointestinal function or for up to 10 days. Primary endpoint: time to recovery of gastrointestinal function. Results Median time to recovery of gastrointestinal function was 2.6 days for both felcisetrag 0.5mg daily and 0.5 mg pre-surgery versus 1.9 days for placebo (p>0.05). There were no notable differences in adverse events between treatment arms. Conclusions Felcisetrag was well tolerated with no new safety concerns. However, no clinically meaningful difference in time to recovery of gastrointestinal function versus placebo was observed. Further investigation of the utility of 5-HT 4 agonists in complicated, open abdominal surgeries may be warranted.
