Clinical Trial Summary

This is a 3 part, phase 1 crossover study in healthy subjects to evaluate the pharmacokinetic profile of KVD824 following single and multiple doses of novel KVD824 modified-release formulations compared with a reference KVD824 immediate release formulation.

Description:

Part 1 of the study was a single-centre, open-label, non-randomised, 6-period crossover study designed to investigate the PK and safety of KVD824 MR prototype formulations (with or without an additional KVD824 IR capsule) compared to a reference KVD824 IR capsule formulation in healthy male and female subjects. Part 2 was an optional part designed to investigate the PK and safety of a selected KVD824 MR prototype tablet formulation (with or without an additional KVD824 IR capsule) in healthy male and female subjects in both the fed and fasted state. Note: this Part was not conducted as sufficient information on food effect was collected in the other Parts of the study.

Part 3 was a single-centre, randomised, double-blind, placebo-controlled, multiple dose group study to investigate the PK and safety of a selected KVD824 MR prototype tablet formulation (with or without an additional KVD824 IR capsule) in healthy male and female subjects. Part 3 started following completion of Part 1.
