Description of intervention(s) / exposure
Placebo-controlled, First-In-Human study assessing the safety and tolerability of PRN473.
Approximately 64 participants in up to 6 cohorts will take part in Part A of the study. Participants in Part A of the study will receive a single dose of PRN473 (starting dose 50mg and increasing each cohort thereafter). Part A participants will receive a liquid formulation whilst fasting with the exception of 2 cross over cohorts; participants in Cohort 4a will receive the liquid formulation administered with and without food (with up to a 7 day washout between doses) and participants in Cohort 4b will be administered a tablet equivalent with and without food (with up to a 7 day washout between doses).
Approximately 50 participants in up to 5 cohorts will take part in Part B of the study. Participants in Part B of the study will receive one dose of PRN473 (tablet or liquid formulation) per day for up to 14 days (doses to be assigned based on data from part A i.e. a dose that gives roughly 30% occupancy of the target). Tablet or liquid formulation will be chosen on the basis of emerging PK and PD data from Part A of the study.
Study subjects are domiciled during the study and adherence will be monitored by study staff observations and notes, and tablet accountability or weighing the dosing syringes before and after dosing as applicable.

Comparator / control treatment
The liquid formulation placebo will be prepared for each cohort at the study site by dissolving the formula amount of hydroxypropyl-beta-cyclodextrin, vitamin E TPGS (d-alpha tocopheryl polyethylene glycol 1000 succinate), citric acid and sucralose in Water for Irrigation.
The placebo tablet is presented as an oval, scored, white tablet of approximately 1 g total weight. The tablet contains the following compendial excipients; hydroxypropyl-beta-cyclodextrin, microcrystalline cellulose, vitamin E TPGS (d-alpha tocopheryl polyethylene glycol 1000 succinate), croscarmellose sodium, and magnesium stearate. The tablets are packaged in high-density polyethylene (HDPE) containers, induction sealed, capped and labelled. Each bottle contains 30 tablets. The tablets are stored at 2–8 degrees celsius. The tablets will be administered orally to the study subject as per the clinical protocol. The tablets should be swallowed without chewing, and followed by the consumption of approximately 240 mL of water.
