Plain English summary of protocol

Background and study aims
GIC-1001 is a drug that is intended to provide analgesia (pain relief) for patients undergoing colonoscopy, where a thin flexible tube with a tiny camera on the end (colonoscope) is used to look inside the bowel. It may later be used for pain management in colonic diseases such as irritable bowel syndrome and ulcerative colitis. The aim of this study is to assess the safety, tolerability (side effects) and pharmacokinetic profile (movement of the drug into, through, and out of the body) of GIC-1001 in healthy volunteers.

Who can participate?
Healthy volunteers aged 18 to 50

What does the study involve?
In Part 1 participants are randomly allocated to take GIC-1001 tablets at one of five doses or placebo (dummy) tablets once a day for 7 days. Up to 21 blood samples are taken over a 36-hour period. In Part 2 participants are randomly allocated to take GIC-1001 tablets at one of four doses or placebo (dummy) tablets three times a day for 7 days. Up to 18 blood samples are taken over a 7-day period. In Part 3 participants take a single dose of GIC-1001 in two periods with and without food to assess the effects of food intake on GIC-1001. A total of 16 blood samples are taken over a 36-hour period. Physical examinations, 24-hour cardiac (heart) monitoring and lab tests are carried out to assess the safety and tolerability of GIC-1001 in all groups.

Scientific titleA double-blind, placebo controlled, phase I study to assess safety, tolerability and pharmacokinetics of single and multiple ascending oral doses of GIC-1001 in normal healthy volunteers
Study acronymGIC-1001
Study objectivesGIC-1001 is a non-centrally-acting, orally-administered, hydrogen sulfide releasing opioid agonist, which intends to provide adequate colonic analgesia to patients undergoing sedation-free colonoscopy.
Ethics approval(s)Institutional Board Review Services, 09/11/2012, ref: IBRS-GIC-1001-09-NOV-2012
Health condition(s) or problem(s) studiedGastroenterology/pain management/management of visceral pain during sedation-free colonoscopy
InterventionExperimental: GIC-1001 oral tablets
GIC-1001; 125 mg oral tablets; Single ascending doses (SAD) from 125 mg to 1000 mg; multiple ascending dose (MAD) from 125 mg to 500 mg TID over 7 successive days

Part 1: Single Doses Cohort A: Single dose of 125 mg of GIC-1001 or placebo; Cohort B: Single dose of 250 mg of GIC-1001 or placebo; Cohort C: Single dose of 375 mg of GIC-1001 or placebo; Cohort D: Single dose of 500 mg of GIC-1001 or placebo; and Cohort E: Single dose of 1000 mg of GIC-1001 or placebo. Up to 21 blood samples will be obtained over a 36 hour period.

Part 2: Multiple Doses, three times a day (TID) during 7 consecutive days; Cohort F: Multiple doses of 125 mg of GIC-1001 or placebo; Cohort G: Multiple doses of 250 mg of GIC-1001 or placebo; Cohort H: Multiple doses of 375 mg of GIC-1001 or placebo; and Cohort I: Multiple doses of 500 mg of GIC-1001 or placebo. Up to 18 blood samples will be obtained over a 7 day period.

Part 3: one single dose of GIC-1001 to be selected for the Food Effect cross-over evaluation. A total of 16 blood samples will be obtained over a 36 hour period.

Placebo Comparator: GIC-1001 matching placebo
Matching placebo, single or multiple dosing

Physical exams, 24 hour cardiac monitoring, and a complete battery of biochemical and hematological lab tests will be done to assess the safety and tolerability of GIC-1001 in all dosing cohorts.

Pharmaceutical study type(s)
PhasePhase I
Drug / device / biological / vaccine name(s)GIC-1001
Primary outcome measureSafety and Tolerability: Single and multiple (7 consecutive days) doses
In this Phase I study, 5 single ascending doses of GIC-1001 will be studied, as well as 4 multiple doses administered during 7 consecutive days ( TID regimen). As well, one single dose will be administered with and without food to assess the effect of food intake on the PK of the study drug. Safety issues monitored.
Secondary outcome measuresPharmacokinetics: Up to 36 hours for single ascending doses; every day and up to 8 hour post last dose for multiple ascending doses
Blood samples will be obtained over a 36 hour period in the single dose portion of the study and over 7 days, every morning prior to GIC-1001, as well as 8 hours post-last dose in the multiple dosing phase. Main absorption and disposition parameters using a non-compartmental approach will be measured.

For GIC-1001 and its metabolites, the pharmacokinetic parameters of interest for the single dose regimens will be Cmax, AUC0-8, AUCT, AUC∞, Tmax, AUCT/∞, Kel, T½el, Cl/F and Vd/F. The parameters Cmax, AUC0-8, AUCT and AUC∞ will be dose-normalized, and their natural logarithm will be calculated. The pharmacokinetic parameters of interest for the multiple dose regimens will be Cmax, Tmax, AUCτ, Cmin, Cpds, Fluctuation and Swing. The parameters Cmax, AUCτ and Cmin will be dose-normalized, and the natural logarithm of Cmax, AUCτ, Cmin and Cpds of will be calculated. For hydrogen sulfide and thiosulfate, the pharmacokinetic parameters of interest will be Cmax, Tmax and AUC0-4.
