Study on Analgesia of GIC-1001 & GIC-1002 on Visceral Pain, Rectal Sensory Threshold Using the Barostat Method

• Status: Completed
• Trial end date: 2014-12-01
• Target enrollment: 0
• Participant gender: All

Summary

This study evaluates colonic analgesia by comparing two novel formulations, GIC-1001 and GIC-1002 with placebo using a barostat distender. The healthy male and female volunteers randomized to one of 5 possible treatments will be exposed to rectal distension following a 3-day treatment TID. The barostat methodology is a well-established and validated way to assess visceral pain. Visceral pain will be evaluated during exposure to varying distender pressures using a visual analog scale.
