Treatment with placebo product |
- Time to gastrointestinal recovery (GIR) [ Time Frame: From the day after surgery until hospital discharge or ≤ 10 days (whichever is earlier) ]Time to achieve recovery of GI motility as measured by a composite endpoint representing upper AND lower GI recovery
- Time to GIR responses [ Time Frame: From the day after surgery until hospital discharge or ≤ 10 days (whichever is earlier) ]Time to first toleration of clear liquids, time to transition from clear liquids to next diet stage (full liquids or solids), time to toleration of solids, time to first bowel movement, and time to absence of distension and presence of bowel sounds and flatus
- GIR outcome related to length of hospitalization [ Time Frame: From surgery to hospital discharge based on GI recovery (up to 2 weeks) ]Total number of calendar days from surgery to ready for discharge based solely on GI recovery
- POI-related morbidity [ Time Frame: From the day after surgery to discharge follow-up visit (30 days (+ 7 days) after hospital discharge) ]Primary POI that is not secondary to surgical complication, such as anastomotic leak, abscess formation, or sepsis that requires readmission within 7 days of discharge, or need for postoperative nasal gastric tube insertion to manage symptoms of POI (vomiting/retching, abdominal distension)
- Safety of TU-100 [ Time Frame: From baseline to discharge follow-up visit (30 days (+ 7 days) after hospital discharge) ]Patient incidence of adverse events (AEs) observed following administration of TU-100.
- Effects of TU-100 on early postoperative surgical outcomes related to mechanism of action [ Time Frame: From the day after surgery to discharge follow-up visit (30 days (+ 7 days) after hospital discharge) ]Subject-reported (electronic diary) for number of episodes of vomiting and/or retching per day and bothersome nausea and abdominal bloating by day, postoperative antiemetic rescue, and postoperative complications
