GIC-1001 is a novel, orally-administered, colonic analgesic drug developed as an alternative to i.v. sedation during full colonoscopy. It will be evaluated for efficacy and safety in a multi-center, randomized, double-blind, placebo controlled, dose-ranging, proof of concept Phase 2a trial. Up to 240 patients will receive one of 3 doses of GIC-1001 or its matching placebo. A pharmacokinetic evaluation will be carried out on a subset of patients (N: 24).

Primary Outcome Measures:
  • Measurements of visceral pain, using a 100-mm Visual Analog Scale (VAS) [ Time Frame: Assessed at different anatomical locations: (1) before colonoscopy, (2) insertion of scope in anus, (3) at rectosigmoid flexure, (4) at splenic flexure, (5) at hepatic flexure, (6) at caecum, (7) at splenic flexure on wayback, (8) after colonoscopy. ]
    The patient will mark the 100-mm VAS line at each anatomical locations. A score (mark) at zero means no pain and a score of 100 means extreme pain experienced. Each VAS score will be associated to an anatomical location, such location being converted into the distance of inserted colonoscope. All data will translate into a curve, where Y-axis is VAS values and X-axis is scope distance, then the AUC will be the overall pain experienced during the colonoscopy

Secondary Outcome Measures:
  • Time to Caecum [ Time Frame: Measured during colonoscopy ]
    Time to Caecum is the time taken by the physician to reach the caecum with the colonoscope, from the insertion in the anus.

  • Colonoscopy completion rate (%) [ Time Frame: Number of patients during trial with a complete colonoscopy, where the scope has reached the caecum during the colonoscopy ]
    Qualitative outcome: colonoscopy completion is defined as a procedure performed entirely, from initial anal insertion, reaching of caecum, and complete removal of the scope. Completion rate is then the number of patient (%) with a complete colonoscopy (up to the caecum) divided by the number of trial participants.

  • Safety [ Time Frame: Assessed before drug treatment, on Day 2 of the 3-day dose regimen, before and after the colonoscopy (Day4), followed by 2 safety call after 48 hours post-colonosocpy and 7 days post-colonoscopy. ]
    Physical exams, safety lab tests, EKG and adverse events reporting

  13. Unexpected and significant visceral pain reported by subject prior to colonoscopy.
  14. Dementia.
