Participants who are receiving behavioral weight loss treatment (BWLT) (e.g., Weight Watchers) that was begun within the 3 months before study entry. Participants who are receiving BWLT that was started 3 months prior to the beginning of the study will be allowed to continue to receive their BWLT during the trial only if they have had no weight loss in the past 3 months and they agree to not make any changes in the frequency or nature of their BWLT during the course of the drug trial. 4.

Have an ECG with significant arrhythmias or conduction abnormalities, which in the opinion of the physician investigator preclude study participation. 10. Have clinically relevant abnormal laboratory results. 11. Participants requiring treatment with any drug which might interact adversely with or obscure the action of the study medication. This includes anti-obesity drugs, psychostimulants, modafinil or armodafinil, topiramate or zonisamide, and antipsychotics. Participants receiving metformin at a stable dose for ≥ 3 months can be included. 12. Participants receiving GLP-1 based therapies, sodium-glucose co-transporter 2 inhibitors (SGLT2s), thiazolidinediones, sulfonylureas, or insulin. 13. Participants with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2. 14.

Participants with a urine drug screen positive for a drug that, in the opinion of the investigator, is being abused. 18. Participants with a past medical history of pancreatitis. 19. Participants who had received any investigational drug within 3 months prior to this trial. 20.
