Other illness

• Have obesity induced by other endocrinologic disorders (for example, Cushing Syndrome) or diagnosed monogenetic or syndromic forms of obesity (for example, melanocortin 4 receptor deficiency, leptin deficiency, or Prader Willi Syndrome) (B) Diabetes-related for participants with T2DM:

Lab values

• Treatment with any medication for the indication of T2DM other than stated in the inclusion criteria within 3 months before screening (i.e. insulin, amylin analogues, glucagon-like peptide-1 receptor (GLP- 1R)) agonists, GLP-1R agonist/insulin/glucose-dependent insulinotropic polypeptide (GIP) combinations, and dipeptidyl peptidase 4 inhibitor (DPP-4i))
• New initiation of any other glucose-lowering investigational drug within 3 months prior to screening for this trial
