Criteria

Inclusion Criteria:

For GPI1 Participants:

• Participants who are unable or unwilling to use PAP therapy. Participants must not have used PAP for at least 4 weeks prior to screening.

For GPI2 Participants:

• Have been on PAP therapy for at least 3 consecutive months prior to screening and plan to continue PAP therapy during the study

For Both GPI1 and GPI2 Participants:

• Have an AHI ≥15 on PSG as part of the trial at screening

• Have a body mass index (BMI) ≥30 kilogram/square meter (kg/m²)

• Have a history of at least 1 self-reported unsuccessful dietary effort to lose body weight

Exclusion Criteria:

For GPI2 Participants:

• Have personal or job-related responsibilities, or in the opinion of the investigator have any situation, that would make it unsafe to stop PAP therapy for 7 days prior to PSG testing during the course of the study

• Are unwilling to stop PAP therapy for 7 days prior to polysomnography (PSG) testing during the course of the study

For GPI1 and GPI2 Participants:

• Female participants must not be pregnant, intending to be pregnant, breastfeeding, or intending to breastfeed.

• Have type 1 diabetes mellitus (T1DM) or type 2 diabetes mellitus (T2DM), history of ketoacidosis, or hyperosmolar state/coma.

• Have HbA1c ≥ 6.5% (≥ 48 mmol/mol) at baseline

• Any previous or planned surgery for sleep apnea or major ear, nose or throat surgery, including tonsillectomy and adenoidectomy that still may affect breathing at time of baseline

• Have significant craniofacial abnormalities that may affect breathing at baseline

• Have diagnosis of Central or Mixed Sleep Apnea with % of mixed or central apneas/hypopneas ≥50%, or diagnosis of Cheyne Stokes Respiration

• Diagnosis of Obesity Hypoventilation Syndrome or daytime hypercapnia.

• Active device treatment of OSA other than PAP therapy (for example, dental appliance), or other treatment, that in the opinion of the investigator, may interfere with study outcomes, unless willing to stop treatment at baseline and throughout the study.

• Respiratory and neuromuscular diseases that could interfere with the results of the trial in the opinion of the investigator.

• Have a self-reported change in body weight >5 kg within 3 months prior to screening

• Have a prior or planned surgical treatment for obesity (excluding liposuction or abdominoplasty if performed more than 1 year prior to screening)

• Have or plan to have endoscopic and/or device-based therapy for obesity or have had device removal within the last 6 months (for example, mucosal ablation, gastric artery embolization, intragastric balloon, and duodenal-jejunal bypass sleeve)
