Subjects are requested to refrain from taking non-approved concomitant medications from recruitment until the conclusion of the study.
27. Any subject who, in the judgment of the Investigator, is likely to be non-compliant during the study, or is unable to cooperate because of a language problem or poor mental
development.
28. Any subject in the exclusion period of a previous study according to applicable regulations.
29. Any subject who is the Principal Investigator or any sub-Investigator, research assistant, pharmacist, study coordinator, or other staff thereof, directly involved in conducting the study.
30. Any subject without a good peripheral venous access.
31. Positive result on any of the following tests: hepatitis B surface antigen (HBs Ag), antihepatitis

Any subject testing positive for acetaminophen (paracetamol) at screening and/or inoculation day may still be eligible for study participation, at the
Investigator’s discretion.

hypomagnesaemia.
- ECG abnormalities in the standard 12-lead ECG (at screening, prior to IMP
dosing,) which in the opinion of the Investigator is clinically relevant or will interfere with the ECG analyses.

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.
