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).

Interventions

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 effe

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.

Inclusion criteria

Healthy volunteer subjects eligible for inclusion in this study have to fulfil all of the following inclusion criteria: 1. Male and female subjects 18-55 years of age, inclusive, at the time of screening 2. Able to provide written informed consent prior to the performance of any study specific procedures 3. Subjects with a BMI between 18.0 and 30.0 kg/m2, inclusive 4. A 12-lead ECG at screening or pre-dose assessment that, in the opinion of the investigator, has no abnormalities that compromise subject’s safety in this study. 5. Female subjects of non-childbearing potential, defined as (1) having a documented tubal ligation at least 6 weeks prior to dosing; (2) having had a surgical bilateral oophorectomy (with or without hysterectomy); (3) at least 12 months of spontaneous amenorrhoea with follicle stimulating hormone (FSH) > 40 MIU/ml. 6. Female subjects of child-bearing potential with negative serum pregnancy test at screening and negative urine pregnancy test at check-in (Day -1), AND; • Agrees to abstinence for the duration of the study and until 4 weeks after dosing with study drug; • OR agrees to use condoms plus a highly-effective form of contraception (associated with a less than 1% failure rate when applied consistently and correctly); i.e. intra-uterine device or hormonal contraception associated with suppression of ovulation, from screening until 4 weeks after dosing with study drug; • OR has only same-sex partners when this is her preferred and usual lifestyle. 7. Male subjects with female partners of child-bearing potential must agree abstinence or to use condoms plus partner use of a highly-effective form of contraception (intrauterine device, hormonal contraception) for the duration of the study and until 12 weeks after dosing with study drug. They must also agree to not donate semen during the same time frame. 8. Negative Human Immunodeficiency Virus (HIV), Hepatitis B and Hepatitis C Screening test results 9. Subjects who are willing and able to comply with all study assessments and adhere to the protocol schedule. 10. The participant will be normotensive at screening with systolic blood pressure (BP) between 95 and 140mmHg, diastolic BP between 50 and 95mmHg, and heart rate (HR) between 55 and 90 beats per minutes (bpm).
