Description of intervention(s) / exposure
This is a an exploratory Phase I, single 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 into 11 cohorts (8 participants per cohort). Eligible participants will be randomised to receive a single dose of ZE63-0302 (6 participants) or placebo (2 participants) administered as an oral capsule on under fed and fasted conditions on Day 1.

The starting dose of ZE63-0302 will be 20mg, with a planned dose range from 20 to 1200 mg to be evaluated across the 11 cohorts and co-administered with HPMCAS and Kolliphor P407 across specific cohorts to assist in absorption of ZE63-0302. 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.

Summary
Brief summary
This is a double-blind, placebo-controlled, First-in-Human Study study to assess the safety of ZE63-0302 ,and how this drug acts in the body in healthy volunteers. ZE63-0302 may be indicated for use in patients with Acute Myeloid Leukaemia (AML), but a trial of the drug in healthy volunteers is needed before trials in AML patients can proceed.

Who is it for?
You may be eligible for this study if you are aged 18 to 55 years and are in good general health without a clinically significant medical history. Participants with a prior cancer diagnosis are not eligible for inclusion in this study.

Study details
All healthy volunteer participants who choose to enrol in this study will be assigned by chance to receive a single dose of ZE63-0302 or placebo. All participants will have their vital signs checked(heart rate, blood pressure, temperature, etc), and will provide blood and urine samples for testing.
It is hoped this research will determine the maximum dose of ZE63-0302 that can be administered safely without causing severe reactions. Once the dose of ZE63-0302 has been determined in healthy volunteers, a trial investigating the efficacy of ZE63-0302 as a treatment for patients with AML may proceed.
