简要总结
The primary purpose of the study is to assess the effect of lorundrostat taken orally (po) once a day on the Apnea-Hypopnea Index (AHI) in participants with moderate to severe obstructive sleep apnea (OSA) and hypertension.
详细描述
The study is a randomized, double-blind (DB), placebo controlled, crossover study. A 4-week screening period is followed by two DB 4-week treatment periods separated by a 2-week washout period. Participants must be 18 to 75 years old with moderate to severe OSA, hypertension and meet all applicable eligibility criteria. Participants who are medically prescribed and deemed compliant with positive airway pressure (PAP) therapy for greater than or equal to (>=) 4 hours per night (Continuous PAP [CPAP], or automatic PAP [autoPAP]) and for at least 3 months prior to the study enrollment are eligible for the study. Participants on PAP therapy should comply with PAP therapy for the duration of the study. Participants who are not currently on PAP therapy and not anticipated to start PAP for the duration of the study, are also eligible for the study.
