Experimental: Part 1 (Formulation Optimisation) - Study drug administered orally after an overnight fast (minimum 8 hours). A standard breakfast will be provided 30 minutes after study drug administration. There will be 4 different formulations of the study drug and participants will be randomised to one of 4 sequences. There will be a washout of 2 days between each administration.

Experimental: Part 2 (Placebo Assessment) - Study 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.

Experimental: Part 3 (Titration Tolerability) - Study 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 will be randomised to either study drug or the matching placebo.
