This research aims to assess the effectiveness and safety of eloralintide in adults with moderate to severe obstructive sleep apnea who are also obese or overweight. The study is organized under a master protocol called YDAO, which supports two separate studies: YSA1 for participants who are unable or unwilling to use Positive Airway Pressure (PAP) therapy, and YSA2 for those who have been using PAP therapy for at least three months and intend to continue it during the study. This is a Phase 3 randomized, double-blind, placebo-controlled trial focused on this specific population. Participants will receive either eloralintide or a placebo, both given by subcutaneous injection once weekly. They will be assigned to one of two groups based on their current PAP therapy use: those not using PAP (YSA1) and those continuing PAP (YSA2). The study treatment and observation will last about 76 weeks, allowing detailed evaluation over time. During the study, participants will undergo assessments including polysomnography to measure the apnea-hypopnea index (AHI) and body weight changes from baseline to week 64. Researchers will monitor weight, sleep apnea severity, and safety throughout the trial. The long participation period includes screening, treatment, and follow-up to capture comprehensive data on eloralintide’s effects and tolerability.
