  • Current or history (within 90 days before screening) of treatment with medications that may cause significant weight gain or loss, including systemic corticosteroids (except for a short course of treatment, i.e., 7 - 10 days), tricyclic antidepressants, atypical antipsychotics and mood stabilizers (e.g., imipramine, amitriptyline, mirtazapine, paroxetine, phenelzine, chlorpromazine, thioridazine, clozapine, olanzapine, valproic acid and its derivatives, and lithium).

A history of marijuana or tetrahydrocannabinol (THC)- product use within 30 days of enrollment and unwillingness to abstain from marijuana or the use of THC-containing products during the trial is also exclusionary. Stable daily CBD use is allowed (stable for \> 30 days prior to randomization and planned continued stable use throughout the trial). Intermittent CBD use is not allowed.
  • Participation in a clinical trial involving the administration of an investigational or marketed drug or device use within 30 days or 5 half-lives, whichever is longer, before IMP administration; administration of a biological product in the context of a clinical trial within 90 days or 5 half-lives before IMP administration, whichever is longer, or concurrent participation in an experimental trial that does not involve the administration of an IMP or device use.
  • Use of drugs and foods including CYP3A4 inhibitors or inducers (Table 10), UGT1A1 substrates and inhibitors, daily use of medications that are substrates of CYP2C8, CYP2C9, or CYP2C19 and have a narrow therapeutic index.
  • Participant unwilling or unable to abstain from using nicotine or tobacco, cigars, cigarettes, e-cigarettes/vaping, pipes, or nicotine patches for 45 minutes prior to trial visits.

Other illness

  • History of significant allergic reaction (e.g., immediate hypersensitivity, significant respiratory and skin symptoms such as Steven Johnson syndrome) or hypersensitivity to any drug.
  • History of clinically significant gastrointestinal disease or surgery that may affect IMP absorption. A history of appendectomy or cholecystectomy is not exclusionary.
  • Obesity induced by other endocrinologic disorder (e.g., Cushing's syndrome).
  • History of clinically significant QTcF interval prolongation, or a QTcF interval of \> 470 ms in females or of \> 450 ms in males at screening.
  • Clinically significant vital sign abnormalities at screening (systolic blood pressure \[SBP\] \< 90 or \> 150 mm Hg, diastolic blood pressure \[DBP\] \< 50 or \> 100 mm Hg, or heart rate \[HR\] \< 50 or \> 100 bpm). Retesting is allowed at the discretion of the site Investigator or designee.
  • History or evidence of any other clinically significant disorder, condition, or disease or any other reason that, in the opinion of the Investigator or physician, would pose a risk to participant safety or interfere with the trial evaluation, procedures, or completion.

Lab values

  • Clinically significant physical examination abnormalities or clinically significant laboratory abnormalities at screening.
  • Current participation (or within the last 90 days) in an organized weight reduction program or currently using or used within 90 days before screening: pramlintide, sibutramine, orlistat, zonisamide, topiramate, phentermine, naltrexone, bupropion, lorcaserin, metformin, or any GLP-1R and/or glucose-dependent insulinotropic polypeptide (GIP) agonists (either by prescription or as part of a clinical trial).
