* Use of intrauterine device, from at least 3 months before the baseline visit through at least 4 months after the last dose of bimagrumab/placebo i.v., and an additional contraceptive (barrier) method from screening through at least 4 months after the last dose of bimagrumab/placebo i.v.
* Body mass index (BMI) = 30 or BMI = 27 with one or more obesity-associated comorbidities (e.g., hypertension, insulin resistance, sleep apnea, or dyslipidemia)
* Stable body weight (± 5 kg) within 90 days of screening, and body weight <150 kg
* Have a history of at least one self-reported unsuccessful behavioral effort to lose body weight
* Able to communicate well with the Investigator, comply with the study requirements and adhere to the diet and activity programs for the study duration

Key exclusion criteria
* History of, or known hypersensitivity to, monoclonal antibody drugs or a contraindication to semaglutide (Ozempic® or Wegovy®)
* Use of other investigational drugs at the time of enrollment or within 30 days or 5 half-lives of enrollment, whichever is longer, or longer if required by local regulations
* Treatment with any medication for the indication of obesity within the past 30 days before screening
* Diagnosis of diabetes requiring current use of any antidiabetic drug or HbA1c = 6.5% Note: Metabolic syndrome is not an exclusion, even if managed with an anti-diabetic drug such as metformin or an SGLT2 inhibitor. A diagnosis of prediabetes or impaired glucose tolerance managed exclusively with non-pharmacologic approaches (e.g., diet and exercise) is not an exclusion.
* Any chronic infections likely to interfere with study conduct or interpretation such as hepatitis B (HBV), hepatitis C (HCV), or human immunodeficiency virus (HIV). History of hepatitis A or hepatitis C successfully treated is not exclusionary. Active COVID-19 infection.
* Donation or loss of 400 mL or more of blood within 8 weeks prior to initial dosing, or longer if required by local regulation, or plasma donation (> 250 mL) within 14 days prior to the first dose
* Any disorder, unwillingness, or inability not covered by any of the other exclusion criteria, which in the Investigator's opinion, might jeopardize the participant's safety or compliance with the protocol
