Brief summary
This phase 1 study is a randomized, placebo-controlled, double-blind, trial of an oral drug called GT 02287 vs. placebo in healthy volunteers. The study will assess the safety, tolerability, Pharmacokinetics, and Food Effect in single and multiple ascending dose cohorts.
Interventions
This is a single centre, randomized, double-blind, placebo-controlled study of single and multiple ascending doses of GT-02287 in healthy volunteers. This study will consist of 2 parts: single and multiple ascending doses of GT-02287. Participants will provide informed consent and undergo screening for the study no more than 28 days prior to Day 1. Eligible participants will check in to the clinical research unit (CRU) on Day -1, the day prior to dosing. All participants in both parts will attend a Follow-up Visit scheduled 7-10 days after their last dose of IP, or after early termination. - Part 1 (single ascending doses; SAD): Study participants will be randomly assigned to receive a single dose of GT-02287 or placebo administered as an oral solution on day 1. There will be 5 ascending dose cohorts in this part with 8 participants per cohort. Sentinel dosing will occur within each cohort. The first 2 participants assigned to each cohort will be randomized 1:1 to GT02287 or placebo. The remaining 6 participants in each cohort will be randomized 5:1 to GT02287 or placebo, for an overall 3:1 randomization ratio for each cohort, including cohort 4. - Cohort 1: 2.4 mg/kg - Cohort 2: 4.8 mg/kg - Cohort 3: 7.7 mg/kg - Cohort 4: 10 mg/kg, then another 10 mg/kg after at a 1-to-2-week washout (FE) - Cohort 5: 12 mg/kg Participants in Part 1 will be confined to the CRU from Day -1 to Day 4, with a single dose of IP administered on Day 1. Participants in Cohort 4 only (the FE cohort) will be recalled, following investigator review of safety data, after a 1-to-2-week washout of their Day 1 dose of IP to assess impact of FE on safety and PK of single dose GT02287. Participants in the FE cohort will be re-admitted to the CRU on FE Day -1 and confined until FE Day 4, with a second single dose of the same allocated treatment on FE Day 1 in a fed state. The enrollment of the next dose cohort will begin only after review of the safety and tolerability data (through Day 4) and available plasma PK data (through the 60-hour post dose sample) for at least 6 out of 8 participants of the previous dose cohort. Part 2 (multiple ascending doses; MAD): This part can begin once safety, tolerability, and PK data are available from the first 3 dose levels from Part 1. Progression to MAD will be confirmed by a blinded Safety Review Committee (SRC). Study participants will be randomly assigned to receive multiple doses of GT 02287 or placebo administered as an oral solution once a day for 14 days. Participants will be confined from Day -1 to Day 17, with once-a-day dosing from Day 1 to Day 14. There will be 4 ascending dose cohorts in this part with 8 healthy adult participants per cohort. The sentinel dosing will not be used, and all participants will be directly randomized in a 3:1 ratio (6 participants will receive GT-02287 and 2 will receive placebo). - Cohort 1: 2.4 mg/kg/day - Cohort 2: 4.8 mg/kg/day - Cohort 3: 7.7 mg/kg/day - Cohort 4: 10 mg/kg/day For all cohorts in both parts, all doses of IP will be administered in a fasted state (other than the second dose for the FE cohort). In Part 1, participants will fast overnight for at least 10 hours before their dose in the morning, followed by an additional 4-hour postdose fast. In Part 2, participants will fast for at least 8 hours overnight predose, followed by an additional 4-hour postdose fast. Water will be allowed as often as desired except for the intervals from 1 hour before dosing to 1 hour after dosing. The second dose of the FE cohort in part 1 will be used to evaluate single-dose PK under fed conditions. Before their dose in the morning, participants will fast for at least 10 hours overnight, then eat a high-fat (=50 percent of total caloric content of the meal), high-calorie (approximately 800 to 1000 calories) meal 30 minutes prior to dose administration. The high-fat meal should be consumed within 30 minutes or less and IP should be administered 30 minutes after the start of the meal. Participants will then fast for at least 4 hours postdose. Water will be allowed as often as desired except the intervals from 10 minutes before dosing to 1 hour after dosing. Individual doses will be provided for participants by Clinical Reasearch Unit staff on the day of administration in 60 mL amber glass bottles with a polypropylene top seal and screw cap. All participants will receive the IP at the study site under the surveillance of appropriate study personnel.
