Outcomes
Primary outcome [1] 338202 0
To evaluate the safety and tolerability of a single dose of PVT201 in healthy participants. This outcome will be a composite outcome.
Timepoint [1] 338202 0
Outcomes will be assessed upon clinic admission at Baseline (Day -1) and Day 1 (prior to dosing), for 24 hours post-dose until Day 2 upon discharge from the clinic, and again on Day 7 post-dose at the final study visit.
Secondary outcome [1] 434955 0
To measure the pharmacokinetics (PK) of PVT201 in plasma following a single dose in healthy participants
Timepoint [1] 434955 0
Blood samples will be collected and measured on Day 1 (within 60 mins prior to dosing), 5, 10, 15, 20, 35, 45 mins, 1, 2, 4, 6, 8 and 12 hours post dose, 24 hours post-dose until Day 2 upon discharge from the clinic, and again on Day 7 post-dose at the final study visit.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be randomized to receive PVT201 or placebo according to the randomisation schedule and plan prepared prior to study start. Code-break tamper-evident envelopes containing treatment allocation per participant will be provided to the study site for emergency unblinding if required.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants who meet the study eligibility criteria will be assigned a randomisation number prior to dosing on Day 1, which corresponds to a study treatment (PVT201 or placebo). The allocation of PVT201 or placebo will be performed using a block randomization algorithm
and will be documented in the study randomization list generated by an unblinded statistician.
