Conditions
Brief summary
This clinical trial is to evaluate the PK, safety, tolerability and food effects of PRAX-562 in healthy participants aged 18 to 55 years inclusive.
Interventions
Participants will be confined at the site during the dosing period where dosing will be done via direct supervision and they can only participate in one of the following parts:
- Part A (oral capsule; screening/ baseline period of up to 28 days with total duration up to 39 days): single ascending doses of PRAX-562 between 2.5 mg and 90 mg (increases of no more than 3 times the previous dose will be based on safety and tolerability at each dose level) or placebo (Day 1) administered under fasting
