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


About the study

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).

Who can take part

You may be eligible to participate in the study if you meet the following criteria:


Inclusion Criteria:

  1. Male or female ≥ 18 years of age

  3. American Society of Anesthesiologists Physical Status Score of 1 to 3
  4. Scheduled for an elective BR via open or laparoscopic approach
  5. Ability to understand the study procedures, have agreed to participate in the study program, and have voluntarily provided informed consent


Exclusion Criteria:

  1. Scheduled for a BR that is not listed in this protocol
  2. Requires any additional resections beyond the intestine (eg, hepatectomy, distal pancreatectomy, pancreaticoduodenectomy, gastric resection, uterine resection), or concomitant surgeries (with the exception of biopsies)
  3. Requires the formation of a stoma (ileostomy or colostomy)
  4. History of surgeries, illness, or behavior (eg, depression, psychosis) that in the opinion of the investigator might confound the study results or pose additional risk in administering the study procedures
  5. Have a functional colostomy or ileostomy
  6. Diagnosed with advanced or metastatic colon cancer (Stage IV by tumor, node, and metastasis classification)
  7. Positive coronavirus disease 2019 (COVID-19) test
  8. 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
  9. Chronic pain syndrome unrelated to the planned surgery requiring consistent management with analgesics and/or other non-pharmacologic modalities
  10. Myocardial infarction within 3 months
  11. Corrected QT interval > 500 msec
  12. Diabetic gastroparesis
  13. Compromised immune system, either from treatment with corticosteroids or other immunosuppressive agent within 2 weeks of surgery or from immunosuppressive disease (HIV)
  14. 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)
  15. 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
  16. Illicit drug use or alcohol abuse based on medical history, or currently engaged in illicit drug use or alcohol abuse
  17. Uses of supplemental ginger, ginseng, or Zanthoxylum fruit within 72 hours before randomization
  18. Has a history of allergic reactions to ginseng, ginger, Zanthoxylum fruit, or lactose
