Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

1. 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
2. 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
3. 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
4. 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
