Safety, tolerability and pharmacokinetics of trimebutine 3-thiocarbamoylbenzenesulfonate (GIC-1001) in a randomized phase I integrated design study: single and multiple ascending doses and effect of food in healthy volunteers.

Purpose: Trimebutine 3-thiocarbamoylbenzenesulfonate (GIC-1001) is a new drug intended to be used for the management of visceral pain in patients undergoing sedation-free, full colonoscopy. The objectives of this Phase I, single-center, randomized, double-blinded, placebo-controlled, integrated study were to evaluate the safety and pharmacokinetics of GIC-1001 after single ascending doses (SAD) and multiple ascending doses (MAD) and to evaluate the influence of food on the pharmacokinetics in healthy volunteers.

Methods: GIC-1001 or placebo was orally administered to 80 healthy male and female subjects (non- or ex-smokers) aged 18 to 50 years with a body mass index between 18.
