A Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamic Effects of KUR-101 in Healthy Adults

This is a Phase 1, single-center, prospective, study of orally administered KUR-101 in normal healthy participants. The study will be conducted in two parts.

Part 1 is a randomized, double-blind, placebo-controlled study to assess the safety, tolerability, PK, analgesic and respiratory effects of single ascending doses of orally administered KUR-101 in normal healthy participants. Once the MTD has been determined, this dose, or an alternate lower dose, will be taken into Part 2 of the study.

Part 2 is a randomized, double-blind, placebo-controlled, three-period crossover study to assess the analgesic and respiratory effects of a single oral KUR-101 as compared to that of oxycodone in normal healthy participants.
