• •Planned chronic use of medications affecting gastrointestinal motility or scheduled gastric emptying-impairing surgery during the study period.
• •Major or medium-sized surgery, or severe trauma or serious infection within 3 months prior to screening, which, as assessed by the investigator, would preclude trial participation, or planned surgery during the study period (excluding outpatient procedures deemed by the investigator to have no impact on subject safety or trial outcomes).
• •History of organ transplant.

• •Participants who may be unable to complete this study for other reasons, or have other conditions that, as assessed by the investigator, will make the participant unsuitable for participation in this study, for example, the participant refuses to use only the weight-loss drugs specified in the protocol during the study.
