This Phase I crossover trial (n=34) will compare the bioavailability of two ketamine formulations (R-107-H vs R-107-P) in healthy volunteers under fasting conditions.
This randomized, double-blind study compares two extended-release tablet formulations containing ketamine, both administered as 3 x 60mg tablets (180mg total dose). The study will take place at Zenith Technology Corporation in Dunedin, New Zealand. The main goal is to determine if the test formulation (R-107-H) has similar bioavailability to the reference formulation (R-107-P) by measuring blood and urine levels of ketamine and its metabolite norketamine over 48 hours after dosing.
Secondary outcomes include safety and tolerability assessments through monitoring of adverse events, vital signs, ECG, and psychiatric rating scales. The study will involve healthy male and female volunteers aged 18-55 with a BMI between 18.5-33.0. Each participant will receive both formulations in random order with at least a one-week washout period between doses. The total study duration is approximately 6 weeks per participant, including screening and follow-up periods.
Trial Details
The primary objective of this study is to evaluate the comparative bioavailability of the test formulation relative to that of a reference formulation, following oral administration of a single dose of 3 x 60 mg R-107-H extended release tablets and 3 x 60 mg R-107-P extended release tablets in healthy participants under fasting conditions. In lay terms this means we are comparing one R-107 formulation (R-107-H) to another R-107 formulation (R-107-P) that both contain the same amount of active ingredient but some of the other ingredients differ between the two making them different formulations of the R-107 extended-release tablet.NCT Number
