Clinical Trial Summary

This is a Phase I Healthy volunteer study with the primary objective to evaluate the safety and pharmacokinetics profile of AX-158. The first part will evaluate single ascending dose administrations. A substudy will be performed as well to evaluate possible impact of food on drug exposure if administered under fasted or fed state. The second part will evaluate multiple ascending dose over 10 days of dosing in fed or fast state depending on the results of the substudy food effect on AX-158.

Description:

This is a phase I, randomised, double-blind , placebo controlled study to investigate the safety, tolerability, and PK of AX-158 in healthy male participants following single (Part A) and multiple (Part C) ascending doses including food effect (Part B).The study will be conducted in three parts (Part A, Part B and Part C). Part A will enrol 8 participants per cohort randomised (3 :1) to receive AX-158 (6 participants) or placebo (2 participants). Part A will follow a single ascending dose (SAD) design with all participants receiving one dose of AX-158 (or placebo) in the fasted state. Part B (Food Effect) will be conducted in 8 participants in a cross-over manner; each participant will receive AX-158 in the fed and fasted state. Part C will enrol 8 participants per cohort randomised to (3 :1) to receive AX-158 (6 participants) or placebo (2 participants). Part C will follow a multiple ascending dose (MAD) design with participants receiving AX-158 (or placebo) once daily for 10 consecutive days, in a fed or fasted state (depending on the outcome of the Part B (Food Effect).

10. Participant must be available to complete the study (including all follow-up visits).

11. Participant must satisfy an Investigator about his fitness to participate in the study.

Exclusion Criteria:

2. Use of prescription or non-prescription drugs, including vitamins, herbal and dietary supplements within 28 days or 5 half-lives (whichever is longer) prior to the first dose of IMP. Occasional use of paracetamol will be allowed.

3. Evidence of renal, hepatic, central nervous system, respiratory, cardiovascular, or metabolic dysfunction.

4. Clinically significant history of previous allergy / sensitivity to AX-158 or any of the excipients contained within the IMP.

5. Participant with history of autoimmune disease, cardiac disease, kidney disease or any food intolerance.

6. Participants with clinically significant abnormal test results for serum biochemistry, haematology and/or urine analyses within 28 days before the first dose administration of the IMP

7. A clinically significant history of drug or alcohol abuse (defined as the consumption of more than 14 units [for male and female participants] of alcohol a week) within the past two years.

8. Inability to communicate well with the Investigators (i.e., language problem, poor mental development, or impaired cerebral function).

9. Participation in a New Chemical Entity (NCE) clinical study within the previous 3 months or five half-lives, whichever is longer, or a marketed drug clinical study within the 30 days or five half-lives, whichever is longer, before the first dose of IMP. (Washout period between studies is defined as the period of time elapsed between the last dose of the previous study and the first dose of the next study).

10. Donation of 450 milliliters or more blood within the 3 months before the first dose of IMP.

11. Vegans, vegetarians, or other dietary restrictions (e.g., restrictions for medical, religious, or cultural reasons, etc), which would prevent participants from consuming a high-fat breakfast or standardised meal.

12. Users of nicotine products i.e., current smokers or ex-smokers who have smoked within the 6 months prior to screening or users of cigarette replacements (i.e., e-cigarettes, nicotine patches or gums).

13. Participants who have received a COVID-19 vaccine injection within 28 days prior to the first dose of IMP.
