Summary

The goal of this randomized, double-blind, multi-dose crossover clinical trial is to determine the safety and efficacy of IHL-42X in subjects with obstructive sleep apnea. The primary endpoint is: Change in AHI4 at the end of each treatment period compared to baseline (each treatment period is 28 days). The study will consist of three separate four-way crossover dose-comparison studies each comparing three dose strengths of IHL-42X to placebo. The double-blind four-way crossover will be conducted according to a Williams design. Each of the crossover studies will test different doses of dronabinol in combination with a distinct, set dose of acetazolamide. In total, nine different combinations of dronabinol and acetazolamide formulated as IHL-42X will be tested in the study. The optimal dose strength will be selected based on safety and efficacy over a 4-week treatment period.
