Clinical Trial Summary

This Phase 1 study is designed to determine the safety, tolerability and pharmacokinetics of PN-232 in healthy volunteers. It is a first-in-human (FIH) study for PN-232 that will be conducted in three parts. Part 1 is a single ascending dose study, Part 2 is multiple ascending dose study, and Part 3 is crossover solid dose comparison and effect of food study.

Description:

Part 1: Approximately 32 subjects will be enrolled into 4 cohorts to receive PN-232 or placebo as single doses. Part 2: Up to 40 subjects will be enrolled into 4 cohorts to receive PN-232 or placebo once daily for 10 days. Part 3: Twelve subjects will receive single doses of PN-232 in a 3-way, randomized, crossover fashion. In total, approximately 84 subjects will participate.
