Safety and Efficacy of TU-100 as an Adjunct to an Enhanced Recovery After Surgery in Subjects Undergoing Bowel Resection

Randomized, Double-Blind, Placebo-Controlled, Phase 2 Trial to Evaluate the Safety and Efficacy of TU-100 as an Adjunct to an Enhanced Recovery After Surgery (ERAS) Protocol in Subjects Undergoing Bowel Resection

This multicenter, randomized, double-blinded, placebo-controlled study will evaluate the effect of TU-100 on resolution of postoperative ileus (POI) in subjects undergoing open or laparoscopic bowel resection (BR).

Study Overview

• Status: Completed
• Conditions: Enhanced Recovery After Surgery
• Intervention / Treatment: Drug: TU-100; Drug: Placebo

Detailed Description

Subjects will be screened up to 28 days before their planned surgery and will be randomized 1:1:1 (TU-100 15 g/day: TU-100 7.5 g/day: placebo) on postoperative Day 1 before the first dose of study medication. After randomization, subjects will receive a total daily dose of TU-100 15g, TU-100 7.5 g, or matching placebo (3 times per day (TID)) until hospital discharge or ≤ 10 days (whichever is earlier). All subjects will be treated with study medication as adjunct to an enhanced recovery (ERAS) pathway for gastrointestinal (GI) recovery.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Time to Gastrointestinal Recovery (GIR)	Time to achieve recovery of GI motility as measured by a composite endpoint representing upper AND lower GI recovery	From the day after surgery (Day 1) until hospital discharge or Day 10 (whichever is earlier)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Time to GIR Responses	Time to achieve first toleration of solid diet AND first bowel movement (Time to GI-2), time to first toleration of clear liquids, and time to absence of distension and presence of bowel sounds and flatus	From the day after surgery (Day 1) until hospital discharge or Day 10 (whichever is earlier)
Time to Discharge	Time at which the subject is considered ready for discharge by the investigator based solely on GI recovery (Time to ready for discharge), and time at which the investigator writes discharge order for the subject (Time to discharge order written)	From surgery to hospital discharge
GIR Outcome Related to Length of Hospitalization (Mean)	Mean number of days that the subject stayed in the hospital calculated based on calendar day of discharge order written	From surgery to hospital discharge
GIR Outcome Related to Length of Hospitalization (Median)	Median number of days that the subject stayed in the hospital calculated based on calendar day of discharge order written	From surgery to hospital discharge
Percentage of GIR Responders	Percentage of subjects who achieve GIR (GIR responders) by day	From the day after surgery (Day 1) until hospital discharge or Day 10 (whichever is earlier)
POI-related Morbidity	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)	From the day after surgery to discharge follow-up visit (30 days (+ 15 days) after hospital discharge)
Number of Participants With Adverse Events	Number of patients with adverse events (AEs) observed following administration of TU-100.	From baseline to discharge follow-up visit (30 days (+ 15 days) after hospital discharge)

Outcome Measure	Measure Description	Time Frame

Subject-Reported Bothersomeness of Nausea	Subjects who answered that they felt nauseous will record bothersomeness of nausea in their eDiaries on all postoperative in-hospital days. Bothersomeness is measured on a scale of 0-10 with 10 being the most bothersome.	From the day after surgery (Day 1) until hospital discharge or Day 10 (whichever is earlier)
Subject-Reported Occurrence of Abdominal Bloating	Subjects will record the occurrence of abdominal bloating in their eDiaries on all postoperative in-hospital days.	From the day after surgery (Day 1) until hospital discharge or Day 10 (whichever is earlier)
Subject-Reported Bothersomeness of Abdominal Bloating	Subjects who answered that they felt bloated will record bothersomeness of abdominal bloating in their eDiaries on all postoperative in-hospital days.
