About
This is a proof-of-concept study to assess the safety and efficacy of Nimacimab Injection compared to an active and placebo injection control.
Full description
The purpose of this study is to measure the change in body weight with once weekly doses of Nimacimab Injection compared with placebo injection and once weekly Nimacimab Injection co-administered with commercially available semaglutide injection (Wegovy®) in participants with obesity or are overweight with weight-related comorbidities.

Have an HbA1c < 48 mmol/mol (6.5%) at screening.
Have had a stable body weight for the 3 months prior to screening (no more than 5% body weight gain and/or loss).
If on cardiovascular, anti-hypertensive, or/and anti-depressant medications, must be controlled on stable dose for 3 months prior to screening.
If on hormone replacement therapy, must be on a stable dose for at least 3 months prior to screening, including use of thyroxine.

Exclusion criteria
Have any prior diagnosis of type 1 or type 2 diabetes mellitus (T1DM or T2DM, or rare forms of diabetes mellitus).
Have at least 1 laboratory value suggestive of diabetes during screening, including 1 or more of HbA1c ≥ 6.5% (48 mmol/mol), fasting serum glucose ≥ 126 mg/dL (7.0 mmol/L), or random glucose ≥ 200 mg/dL (11.1 mmol/L).

Known malignancy that is progressing or has required active treatment within the past 3 years prior to screening. Any exceptions must be approved by the Medical Monitor.
Note: Participants with basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or carcinoma in situ (e.g., breast carcinoma, cervical cancer in situ) that have undergone potentially curative therapy are not excluded.

History or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the participants' participation for the full duration of the study, or is not in the best interest of the participants to participate in the opinion of the Investigator.
Have history of any of the following:
Have a Patient Health Questionnaire-9 (PHQ-9) score ≥ 15 at screening and/or Day 0 (Baseline).
