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.

Part 2 (Placebo Assessment)AC-OLE-PStudy drug administered orally after an overnight fast (minimum 8 hours). A standard breakfast will be provided either 30 minutes before or after study drug administration, depending on the results of the food effect assessment. Participants are randomised to 1 of 2 sequences (tricaprilin formulation - matching placebo; matching placebo - tricaprilin formulation) with a 2-day washout between periods.

Primary Outcome Measures
NameTimeMethod
Maximum observed concentration (Cmax) of total ketones (β-hydroxybutyrate and acetoacetate) after single-dose administration of tricaprilin and placebo formulations (Part 1, Part 2)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)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)0 to 8 hours post-dose

Tmax will be calculated from PK concentrations of total ketones (B-hydroxybutyrate and Acetoacetate)

Secondary Outcome Measures
NameTimeMethod
Gastrointestinal side effects of single-dose administration of each of tricaprilin formulations and the placebo formulation (Parts 1, 2) assessed using the Baxter Retching Faces ScalePre-dose, 0.5, 1, 1.5, 2, 3 hours post-dose

The Baxter Retching Faces Scale is a pictorial scale rated from 0 to 10, with 6 faces depicting level of nausea/gastrointestinal discomfort.

Area under the concentration-time curve (AUC) of total ketones (β-hydroxybutyrate and acetoacetate) of tricaprilin and placebo formulations following a titration scheme (Part 3)Days 15 and 21: 0 to 8 hours post-dose; Day 27: 0 to 24 hours post-dose

AUC will be calculated from PK concentrations of total ketones (B-hydroxybutyrate and Acetoacetate)

Incidence of treatment emergent adverse eventsBaseline to end of treatment period

Adverse event incidence will be tabulated

Gastrointestinal side effects of single-dose administration of each of tricaprilin formulations and the placebo formulation (Parts 1, 2) assessed using the Pain Numerical Rating ScalePre-dose, 0.5, 1, 1.5, 2, 3 hours post-dose

The Pain Numerical Rating Scale 10-point numeric rating scale with participants instructed to rate any abdominal pain from 0 (no pain) to 10 (worst possible pain)

Maximum observed concentration (Cmax) of total ketones (β-hydroxybutyrate and acetoacetate) of tricaprilin and placebo formulations following a titration scheme (Part 3)Days 15 and 21: 0 to 8 hours post-dose; Day 27: 0 to 24 hours post-dose

Cmax 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) of tricaprilin and placebo formulations following a titration scheme (Part 3)Days 15 and 21: 0 to 8 hours post-dose; Day 27: 0 to 24 hours post-dose

Tmax will be calculated from PK concentrations of total ketones (B-hydroxybutyrate and Acetoacetate)
