Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Part A, Single Ascending Dose (SAD), involves the oral capsule administration of 0.5 mg up to 24 mg (proposed dose levels are 0.5mg, 2mg, 6mg, 12mg, 24mg) of AK-119, each participant consuming one dose only. The one selected dose cohort will return for a food effect evaluation after at least a 7-day wash-out. The selected dose cohort will participate in a two-way crossover design and return to the clinical unit to receive AK-119/placebo administration of the same for evaluation of the food effect after a washout of at least 7 days. Subjects will undergo the same study assessments in Period 2 as in Period 1, byby the Safety Review Committee (SRC), and will have their follow-up assessment visit 7 days after dose administration in their second period. Subjects will be randomised to receive either no breakfast or a high fat breakfast on the first period and the alternate breakfast in the second period. The cohort and dose selected for the food effect evaluation may be changed after review of the safety data from the first two cohorts of Part A. This part of the study can be conducted in parallel to the higher determined dosing for the subsequent groups. Part B, Multiple Ascending Dose (MAD): up to 16 (2 cohorts) of healthy volunteers will be dosed daily for seven days. Part C, Multiple Ascending Dose (MAD): One cohort of up to 8 healthy volunteers will be dosed daily for up to 28 days. The dose levels for Parts B and C will be selected following review of safety and pharmacodynamics data from the preceding part(s) of the study. Drug will be administrated at the site under supervision of trained staff monitoring adherence.

Summary
Brief summary
This is a single centre, randomized, double-blind, placebo-controlled, sequential, single dose-escalation study of AK-119 administered to healthy adults and multiple dose-escalation study of AK-119 administered to healthy adults. The study comprises three parts A,B & C.
Part A of the study is a single dose escalation arm. The safety data will be reviewed after each Cohort prior to dose escalation. The selected dose cohort will participate in a two-way crossover design and return to the clinical unit to receive AK-119/placebo administration of the same for evaluation of the food effect after a washout of at least 7 days.
In Part B All subjects will be admitted to the Phase 1 unit on Day -1 for pre-treatment assessments then given a single dose of AK-119 or placebo once or twice daily from Day 1 to Day 7. They will remain inpatients until Day 10, returning as outpatients for follow-up assessments on Day 14. Part C will start after completing the multiple dose, dose escalation components in healthy volunteers in Part B, one cohort with healthy volunteers will be enrolled to receive 1 dose level of AK-119/placebo, as determined from the Part B in healthy volunteers. The dosing period will be upto 28 days as once or twice daily, commencing on Day 1 (dosing regimen to be determined from Part B).
