Brief summary
Placebo-controlled, First-In-Human study assessing the safety and tolerability of PRN1008 in healthy volunteers. Participants will be randomised to receive a single oral dose of PRN1008 or a single oral dose of placebo. Up to four cohorts of eligible participants will be studied.
Interventions
This placebo-controlled, First-In-Human study is looking at the safety and tolerability of a single dose and multiple dose of study drug PRN1008 in healthy volunteers. The study is designed into two parts: Single Dose (Part A): Each participant will be randomised to receive either a single dose (50mg, 150mg, 300mg, 600mg, 1200mg or 1800mg) of PRN1008 oral liquid or a single dose of matching placebo (6 active: 2 placebo, N=8 per cohort). 6 dosing cohorts may be evaluated. Dosing will be escalated upon review of safety and tolerability of each cohort. Multiple Dose (Part B) Each participant will be randomised to receive active or placebo drug either once daily (orally) or twice daily (orally) for ten days. Up to five cohorts of eligible participants will be studied. The planned doses of either PRN1008 oral liquid or matching placebo are 300mg once daily, 300mg twice daily, 600mg once daily or 900mg once daily (8 active: 2 placebo, N=10 per cohort) An optional cohort of either 600mg twice daily or 1200mg once daily may be studied depending on the evaluation of the PK, PD and safety data. 6 dosing cohorts may be evaluated. Dosing will be escalated upon review of safety and tolerability of each cohort For both Part A and Part B, All doses will be administered in the clinic and directly observed by study personnel to ensure compliance. Participants in Part A will be admitted to the clinic on day -1 and remain domiciled until day 3. Participants in Part B will be admitted on Day -1 or -2 and domiciled until Day 12.
