Potential Food Effect And Repeated Dosing of AX-024.HCl In Healthy Subjects

A Safety, Tolerability, and Pharmacokinetic Clinical Trial of AX-024.HCl to Evaluate A) Potential Food Effect and B) Multi-dosing in Healthy Male Subjects

Part A: Food effect (a single oral dose of 500 mg AX-024.HCl under fasted and fed states) Eight (8) healthy male volunteers will receive a single dose of 500 mg AX-024.HCl in the fasted state (10 h overnight fast), and will return 2 weeks later to receive the same dose of AX-024.HCl following a meal.

Part B: Multiple doses (a once daily dose of AX-024.HCl or Placebo for 10 days).

Part B is a double-blind, dose escalating, placebo controlled, randomised, multiple dose study to assess the tolerability, safety and pharmacokinetics in 24 healthy male subjects. Subjects will be allocated to one of 2 dosing cohorts. Each cohort will have 12 subjects with 9 subjects randomised to receive AX-024.HCl and 3 subjects randomised to receive placebo.

There will be a data review following each dose level. Dose administration in the subsequent cohorts will only proceed after satisfactory data review on the blinded safety data and plasma PK data in the previous cohort.

Inclusion Criteria:

• Subject with no clinically significant abnormalities in 12-lead electrocardiogram (ECG) determined within 21 days of the first dose.
• Subject with no history of autoimmune disease, cardiac disease, kidney disease or any food intolerance.
• Male subject willing to use 2 effective methods of contraception i.e. established method of contraception + condom, if applicable (unless anatomically sterile or where abstaining from sexual intercourse is in line with the preferred and usual lifestyle of the subject) from Day 1 until 3 months afterwards.
• Subjects must be available to complete the study (including follow-up visit).
• Subjects must satisfy a medical examiner about their fitness to participate in the study
• Subjects must provide written informed consent to participate in the study
