- •Diseases interfering with metabolism and/or ingestive behavior (e.g., myxedema, Cushing's disease, schizophrenia, major psychoses).
- •History of major depressive disorder within the previous two years, a lifetime history of suicide attempt, suicidal behavior within the previous month, or history of other severe psychiatric disorders.
- •Score of >15 on the Columbia Suicide Severity Rating Scale (C-SSRS).
- •Use of medications affecting body weight within the past three months:
- •Drugs approved for the treatment of obesity

- •Any clinically significant abnormality following the Investigator's review of the physical examination and clinical laboratory tests.
- •A baseline prolongation of QT/QTc interval after repeated measurements of >450 ms; a history of unexplained syncope, cardiac arrest, unexplained cardiac arrhythmias or torsades de pointes, structural heart disease, or a family history of Long QT Syndrome (LQTS).
- •Participation in an investigational drug trial within the month prior to dosing in the present study.
