Overview
Brief Summary
The purpose of this study is to evaluate the pharmacokinetics, safety, and tolerability of new liquid formulations of tricaprilin, with the aim of finding a suitable formulation to advance in development. This is a three-part, part-randomised study that include single-dose, food effect, and titration tolerability in up to 80 healthy participants.

Primary Outcomes
Maximum observed concentration (Cmax) of total ketones (β-hydroxybutyrate and acetoacetate) after single-dose administration of tricaprilin and placebo formulations (Part 1, Part 2)
Time Frame: 0 to 8 hours post-dose
Cmax will be calculated from PK concentrations of total ketones (B-hydroxybutyrate and Acetoacetate)
Area under the concentration-time curve (AUC) of total ketones (β-hydroxybutyrate and acetoacetate) after single-dose administration of tricaprilin and placebo formulations (Part 1, Part 2)
Time Frame: 0 to 8 hours post-dose
AUC will be calculated from PK concentrations of total ketones (B-hydroxybutyrate and Acetoacetate)
Time of maximum concentration (Tmax) of total ketones (β-hydroxybutyrate and acetoacetate) after single-dose administration of tricaprilin and placebo formulations (Part 1, Part 2)
Time Frame: 0 to 8 hours post-dose
Tmax will be calculated from PK concentrations of total ketones (B-hydroxybutyrate and Acetoacetate)
