Post-operative administration of ipamorelin is expected to reduce time to recovery of Gastrointestinal (GI) function in patients who have undergone partial small and/or large bowel resection.

Condition Intervention Phase
Gastrointestinal Dysmotility
Drug: Saline Solution for Injection
Drug: Ipamorelin
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Participant, Care Provider, Investigator, Outcomes Assessor
Primary Purpose: Treatment
Official Title: Phase II Double-Blind Placebo-Controlled Dose Finding Study to Evaluate Safety/Efficacy of Ipamorelin Compared to Placebo for Recovery of Gastrointestinal Function in Patients Following Small or Large Bowel Resection w/Primary Anastomosis

Further study details as provided by Helsinn Therapeutics (U.S.), Inc:

Primary Outcome Measures:
  • Recovery of Gastrointestinal (GI) Function [ Time Frame: Up to 10 days ]
    To assess the efficacy of three repeated dose levels of ipamorelin vs. placebo

Secondary Outcome Measures:
  • Ancillary GI Functions [ Time Frame: Up to 10 days or until hospital discharge ]
    To investigate the effect of ipamorelin on ancillary efficacy measures of GI function and recovery

  • Number of Subjects with Adverse Events as a Measure of Safety and Tolerability [ Time Frame: 14 day outpatient follow-up visit ]
    To investigate the safety and tolerability of ipamorelin laboratory and clinical parameters, incidence of adverse events, until hospital discharge, 14-day outpatient follow-up visit, or until resolution of adverse events
