Completed · Phase 2 · Has a placebo group

Conditions studied: Obesity

In brief

To evaluate the weight loss effect and safety of 400 mg velneperit and 120 mg orlistat administered individually or combined three times per day for 24 weeks while on a reduced calorie diet (RCD) and also to evaluate the steady-state trough concentrations of velneperit (S-2367), velneperit (S-2367) tert-butyl OH, and velneperit (S-2367) tert-butyl OH-O glucuronide following 400 mg of velneperit (S-2367) three times per day and 120 mg of orlistat, either combined or separate.

• Negative urine drug screen for drugs of abuse
• No clinically significant findings on medical history, physical examination, and electrocardiogram (ECG) and no known history of clinically significant ECG abnormalities
• Negative serum pregnancy test in women of child-bearing potential (Females must be at least one year post-partum.)
• Males either should remain abstinent, be sterile or agree to use an approved method of contraception (which for males includes use of a condom with spermicide) Visit 1 through 12 weeks following the last dose, in addition to having a female partner use an effective form of contraception as noted below
