简要总结
- To evaluate the weight loss effect of 1600 mg/day S-2367 administered orally once daily with the morning meal after a 6-week low calorie diet (LCD) of 950 kcal/day with or without S-2367 followed by 54 weeks while on a 800 kcal deficit reduced calorie diet (RCD) compared with placebo in medically stable and otherwise healthy obese male and female subjects
- To evaluate the safety and tolerability of 1600 mg/day S-2367 administered orally once daily with the morning meal after a 6-week LCD with or without S-2367 followed by 54 weeks on a RCD compared with placebo in medically stable and otherwise healthy obese male and female subjects
- To evaluate the steady-state/trough pharmacokinetics of 1600 mg/day S-2367 administered orally once daily with the morning meal after a 6-week LCD with or without S-2367 followed by 54 weeks on a RCD in obese male and female subjects
- To evaluate the weight loss effect of 1600 mg/day S-2367 administered orally once daily with the morning meal during an initial 6-week LCD compared with placebo in medically stable and otherwise healthy obese male and female subjects

- •Clinical laboratory evaluations (including clinical chemistry [fasted at least 8 hours], complete blood count, urinalysis, including creatine phosphokinase, amylase, lipase, lipid profile, insulin, Homeostatic Model Assessment of Insulin Sensitivity Index, hemoglobin A1c, thyroid stimulating hormone, free thyroxine, cortisol, iron, and ferritin) within the reference range for the test laboratory, unless deemed not clinically significant by the investigator
- •Males will be sterile or agree to use an approved method of contraception. Some of the approved methods of contraception for males includes a surgically sterile (for at least 3 months prior to Visit 1) female sexual partner; a postmenopausal (for at least 1 year since last menstrual cycle) female sexual partner; a female sexual partner who uses (for at least previous 3 months prior to Visit 1 and during study) oral, implantable, transdermal, or injectable oral contraceptives; or use of the following double-barrier method: male condom with spermicide
- •Females will be non-pregnant, non-lactating, and either postmenopausal for at least 1 year since last menstrual period, surgically sterile for at least 3 months prior to Visit 1, or agree to use an approved method of contraception. Some of the approved methods of contraception for females include a sterile (for at least 3 months prior to Visit 1) male sexual partner; use of oral, implantable, transdermal, or injectable oral contraceptives; or use of one of the following double-barrier methods: intrauterine device with spermicide, diaphragm with spermicide, cervical cap with spermicide, female condom with spermicide, or a male condom with spermicide by the male sexual partner

- •History or evidence of a psychological disorder, other than stable or controlled anxiety or depression, including but not limited to the schizophrenias. Treatment with an antidepressant or anxiolytic drug(s) will be permitted if the dose and form has remained stable for at least the previous 3 months and the medication is not precluded/ excluded by this protocol because of potential effects on body weight and is not expected to change during the remainder of this clinical protocol
- •History or evidence of an eating disorder with a compensatory behavior such as "purging bulimia nervosa" or "non-purging bulimia nervosa"
- •History of obesity of endocrine origin
- •History of Type 1 or Type 2 diabetes mellitus
- •Clinically significant hypertension defined as blood pressure > 160/90 mm Hg for either the systolic or diastolic values in either the untreated or treated state
- •Clinically significant GI history or surgery. NOTE: Appendectomy and cholecystectomy will be allowed
- •Gastric bypass surgery, stomach banding surgery, or any other surgical procedure(s) that attempt to promote/aid weight loss
- •History of polycystic ovarian syndrome
- •History of fenfluramine or dexfenfluramine or "fen-phen" administration with abnormal findings on echocardiograms at the time of "fen-phen" discontinuation
- •History of participation in any weight loss program within 3 months prior to Visit 1
- •History of body weight loss or gain greater than 3% within 3 months prior to Visit 1
- •History of alcoholism or drug addiction/ substance abuse within 1 year prior to Visit 1
- •History of any tobacco-containing or nicotine-containing product use within 1 year prior to Visit 1
- •Participation in any other investigational study drug trial in which receipt of investigational study drug occurred within 3 months prior to Visit 1
- •Previous use or participation in a study of S-2367 or any other neuropeptide Y5 agonist or antagonist
- •Participation in any weight loss medication/product study in which receipt of weight loss medication/product occurred within 3 months prior to Visit 1
- •Use of any prescription or non-prescription over-the-counter (OTC) medication/product or herbal/phytotherapeutic/plant-derived medications/products within 3 months prior to Visit 1 that is intended to induce weight loss, appetite suppression, weight control, or treat obesity
- •Use of chronic medications/products within 3 months prior to Visit 1 or during the study that are known to cause weight gain. The list includes but is not limited to amitriptyline (Elavil), paroxetine (Paxil), setraline (Zoloft), and mirtazepine (Remeron)
- •Use of any prescription or non-prescription OTC medications/products within 1 month prior to Visit 1, unless deemed acceptable by the investigator.
- •Donation of blood or blood products 3 months prior to Visit 1 or during the entire study
- •Any acute or chronic condition that, in the opinion of the investigator, would limit the subject's ability to complete and/ or participate in this clinical study
