  • \-- Anti-obesity agents or weight-loss medications (including dietary supplements and herbal medicine) within 12 weeks before screening
  • Corticosteroids administered for 2 consecutive weeks or more within 12 weeks before screening (however, topical preparations, including inhalants, are allowed)

  • Tricyclic or Tetracyclic antidepressant, ④ Triazolopyridine antidepressant, ⑤ Selective serotonin (5-HT1) agonists (Sumatriptan, etc.), (However, amitriptyline ≤50 mg/day, trazodone ≤100 mg/day, citalopram ≤20 mg/day, sertraline ≤100 mg/day, paroxetine ≤30 mg/day are allowed; long half-life serotonergic drugs (e.g., fluoxetine) require at least a 5-week wash out period before enrollment),
  • Lithium, Bupropion, Lamotrigine, Ritonavir, Cyclobenzaprine, or St. John's wort within 2 weeks before baseline
  • Hypertension crisis-inducing drugs (e.g., oxymetazoline, phentermine, phenylephrine) within 2 weeks before baseline
  • Sympathomimetic agents (e.g., ephedrine, methylphenidate, amphetamine, methamphetamine, lisdexamfetamine) at the time of screening
  • Dextromethorphan at the time of screening
• Subjects who have participated in another clinical trial and received an investigational drug or device within 4 weeks prior to screening

Other illness

• Subjects with obesity due to secondary causes (neurological disorders, endocrine disorders, genetic disorders, congenital disorders, etc.)
• Subjects with following medical history,
  • Type 1 or Type 2 diabetes
  • History of bariatric/metabolic surgery (e.g., adjustable gastric banding, intragastric balloon insertion, sleeve gastrectomy, Roux-en-Y gastric bypass, biliopancreatic diversion, duodenal switch) or planning to undergo such surgery during the study period
  • Heart failure classified as NYHA class IV
  • Subjects with a medical history of malignant tumors within 5 years prior to screening (however, subjects with successfully treated basal cell carcinoma, squamous cell carcinoma of the skin, thyroid cancer, or other carcinoma in situ, with no recurrence for more than 3 years, may be enrolled at the investigator's discretion)
  • Subjects with a medical history of hypersensitivity to MAO inhibitors
  • Subjects with a medical history of cerebrovascular disease (e.g., transient ischemic attack, stroke) within 12 weeks prior to baseline, or those hospitalized for unstable angina or congestive heart failure
  • Subjects with a history of depressive disorders or psychiatric disorders (e.g., schizophrenia, bipolar disorder, anxiety disorder) within 2 years prior to screening
• Subjects with a lifetime history of suicide attempts
• Other reasons (such as a medical history of alcohol or substance abuse) that the investigator deems the subject unsuitable for participation in this clinical trial

Lab values

• Subjects who meet following criteria based on the tests conducted at Screening
  • Glycated hemoglobin (HbA1c) ≥6.5%
  • Hepatic impairment (Child-pugh class C)
  • AST or ALT \> 2.5 X ULN
  • Total bilirubin \>1.5 X ULN (however, \>3.0 mg/dL is acceptable in cases of Gilbert syndrome)
  • Severe renal impairment (eGFR \<30 mL/min/1.73 m² calculated using the MDRD formula\*),
  • \* eGFR = 175 X (Serum creatinine)-1.154 X (Age)-0.203 X (0.742 (for females)) X (1.212 (for African Americans))
  • TSH \>6.0 mIU/L or \<0.4 mIU/L,

Age

• Females of childbearing potential and males who do not agree to use adequate contraception# until at least 2 weeks after the last dose of the IP or who plan to conceive during the study period,
  • Adequate contraception is defined as double contraception using both barrier methods (male condom or female condom) and one of the contraceptive methods ①-③.
  • Hormonal contraceptive (oral, injectable, implantable, etc.), ② Implantation of Intrauterine device (IUD) or intrauterine system (IUS), ③ Sterilization procedures or surgeries (bilateral tubal ligation, hysterectomy, vasectomy), ④ Complete abstinence: absolute abstinence is accepted if, in the investigator's judgment, the subject's age, occupation, lifestyle, or sexual orientation ensure compliance with contraception. However, periodic abstinence (calendar method, ovulation method, symptothermal method, etc.) withdrawal, and coitus interruptus are not considered adequate contraceptive methods.,

Other
