Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The clinical unit pharmacist will allocate a randomisation number (generated using SAS® software by the Sponsor) to each subject as per the randomisation schedule. Pharmacist will have unblinded envelopes and there will be code break envelopes for emergency use only (with sponsor approval).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The clinical unit pharmacist will allocate a randomisation number (generated using SAS® software by the Sponsor) to each subject as per the randomisation schedule immediately before the administration of ZY-19489 or placebo. Block randomisation will be generated to divide the subjects in each cohort.

Part 1, Single Ascending Dose:
All subjects who satisfy the inclusion and exclusion criteria will be randomized to either ZY-19489 or Placebo in a 6:2 ratio within a cohort. The first two patients in each cohort will be randomized in a 1:1 ratio to ZY-19489 or Placebo and the remaining patients in the cohort will be randomized in a 5:1 ratio to ZY-19489 or Placebo.

Cohort 6 enrollment: Due to COVID-19, recruitment paused after randomisation of the two sentinel participants. When recruitment restarted, the remainder of the 6 participants were divided into 2 (of 3 participants each) sub-cohorts for safety reasons. The M:F ratio was still maintained for Cohort 6.

Summary
Brief summary
This study represents a first-in-human clinical trial for ZY-19489 and aims to determine the safety, tolerability and pharmacokinetics activity of the drug when administered to healthy human subjects. The study will be conducted in three parts. This registration is for Part 1. Part 1 will be a single ascending dose) study which will provide information on the safety, tolerability and pharmacokinetic profile of different single oral doses of ZY-19489 administered to fasted subjects. It will be conducted in up to 7 cohorts of 8 subjects each. Each cohort will be enrolled within a 28 day screening period to ensure subjects meet all the inclusion criteria and none of the exclusion criteria. Subjects will be randomised within each cohort to receive a single oral dose of ZY-19489 or placebo on Day 0 after an overnight fast of at least 10 hours in a ratio of 6:2. A sentinel dosing strategy will be employed for each dose cohort. Two sentinel subjects (one subject randomised to ZY-19489 and the other subject randomised to placebo) will be dosed and a review of the blinded safety data obtained up to 48 hours post-dosing will be conducted by the Investigator. If no safety concerns are identified, the remaining 6 subjects of the cohort will be dosed (5 subjects randomised to ZY-19489 and 1 subject randomised to placebo).
Adverse events and concomitant medications will be followed throughout the study.
The study will be over-sighted by Principal Investigator, Dr James McCarthy, an Infectious Diseases physician experienced in the conduct of malaria challenge studies.
