Inclusion criteria

Obesity, defined as BMI between 30-50 kg/m2, inclusive, with weight at Screening not to exceed 159 kg (350 lbs)
At least one self-reported, unsuccessful attempt at weight loss with lifestyle modification
No abnormal finding of clinical relevance at Screening that could adversely impact participant safety during the study or adversely impact study results
Participants of childbearing potential must agree to use highly effective contraception during the study and for at least 90 days following the end of the study or last dose of study drug, whichever is later. Participants must not donate sperm or eggs during the study for at least 90 days following the end of the study or last dose of study drug, whichever is later

Exclusion criteria

Self-reported (or documented) weight gain or loss >5% within 3 months prior to Screening
Use of GLP-1RAs (liraglutide, semaglutide, etc.) for any indication within 6 months prior to Screening
Use of non-GLP-1R medications for weight loss within 3 months prior to Screening including but not limited to naltrexone/bupropion, orlistat, phentermine/topiramate and other prescription or over-the-counter medication or supplement taken for weight loss purposes
Obesity attributable primarily in the Investigator's opinion to medication use, monogenic or endocrinologic disorders (other than polycystic ovary syndrome)
History of prior surgical or device-based therapy for obesity (including endoscopic bariatric procedures)
Use of medications or therapies strongly associated with weight gain, alterations in body composition, or increase in muscle mass, within 3 months prior to Screening
Type 1 diabetes mellitus

Note: Additional inclusion/exclusion criteria may apply per protocol
