Description of intervention(s) / exposure
This is a an exploratory Phase I, single and multiple dose escalation clinical trial conducted in healthy volunteers. The safety, tolerability, Pharmacokinetics (PK) and Pharmacodynamics (PD) of ZE63-0302 following oral administration in healthy volunteers will be evaluated using a randomised, double-blind, placebo-controlled trial design.

A total of up to 88 healthy volunteers are planned to be enrolled in up to 7 Single Ascending Dose (SAD) cohorts and up to 4 Multiple Ascending Dose (MAD) cohorts . Eligible participants will be randomised to receive a single or multiple dose of ZE63-0302 or placebo administered as an oral capsule on under fasted or fed conditions depending on cohort.

Part A (SAD): The starting dose of ZE63-0302 will be 20mg, with a planned dose range from 20 to 600 mg to be evaluated across 7 SAD cohorts with one cohort to additionally receive 200 mg itraconazole on Day -4 and Days 3 - 8. The decision to escalate between dose levels will be based upon review of the safety data and available PK data of each cohort by the Safety Review Committee (SRC).

Part B (MAD): A planned dose range of 300 to 600 mg of ZE63-0302 or placebo is to be evaluated across up to 4 MAD cohorts. MAD cohort dosing will be either a single oral dose 600 mg once daily for 7 days or 300 mg twice daily for 7 days under fasted / fed conditions depending on cohort. The decision to escalate between dose levels will be based upon review of the safety data and available PK data of each cohort by the Safety Review Committee (SRC).

Participants in the fed cohorts will be provided with a high-fat, high-caloric meal after a 10 hour fast overnight, consisting of the following: two eggs fried in butter, two rashers of bacon, two slices of toast with 16 g butter per slice, 125 g of hash brown potatoes and 240 mls of whole milk. ZE63-0302 or placebo will be administered following the consumption of the meal.

Adherence to the intervention will be done via supervised drug administration.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All study participants who sign an informed consent form (ICF) at screening will receive a unique sequential number (i.e., a Screening Number).
Participants who meet the study eligibility criteria will be assigned a randomisation number pre-dose on Day 1, which corresponds to a study treatment (ZE63-0302 or placebo). Sealed participant-specific code break envelopes will be produced by the unblinded statistician(s) and will be retained at the clinical facility in a secure, accessible location.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The allocation to ZE63-0302 or placebo will be performed using a block randomisation algorithm and will be documented in the study randomisation schedule. The randomisation schedule will be prepared by an unblinded statistician and maintained under controlled access.
