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

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.

Exclusion criteria

• Scheduled for a BR that is not listed in this protocol
• Requires any additional resections beyond the intestine (eg, hepatectomy, distal pancreatectomy, pancreaticoduodenectomy, gastric resection, uterine resection), or concomitant surgeries (with the exception of biopsies)

• Positive coronavirus disease 2019 (COVID-19) test
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection (including human immunodeficiency virus (HIV)), diabetes, symptomatic congestive heart failure and ejection fraction < 35%, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with protocol requirements

• Pregnant (identified by a positive serum pregnancy test) or lactating, or are not postmenopausal (no menses for at least 1 year) and are of childbearing potential and not using an accepted method of birth control (surgical sterilization, intrauterine contraceptive device, oral contraceptive, diaphragm, or condom in combination with contraceptive cream, jelly, or foam or abstinence)
• Participated in another investigational drug/biologic or medical device study within 30 days of surgery or will be enrolled in another investigational drug or medical device study, or any study in which active subject participation is required outside routine hospital data collection during the course of the study
• Illicit drug use or alcohol abuse based on medical history, or currently engaged in illicit drug use or alcohol abuse
• Uses of supplemental ginger, ginseng, or Zanthoxylum fruit within 72 hours before randomization
• Has a history of allergic reactions to ginseng, ginger, Zanthoxylum fruit, or lactose

• Unwilling or unable to comply with procedures described in this protocol or is otherwise unacceptable for enrollment in the opinion of the investigator
• Has a history of previous surgeries, illness (interstitial pneumonia), or behavior (depression, psychosis) that, in the opinion of the investigator, might confound the study results or pose additional risk in administering the study procedures
