Primary Outcome Measures:
  • All treatment-emergent adverse events occurring during the 24-week treatment period [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
  • Absolute change in body weight from baseline to Week 12 [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Percent change in body weight from baseline to Week 12 [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Percentage of subjects achieving at least 5% weight loss from baseline to Week 12 and Week 24 [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
  • Absolute and percent changes in body weight from baseline to Week 2, Week 4, Week 8, Week 16, Week 20, and Week 24 [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
  • Absolute changes in anthropometric measurements (hip and waist circumferences) from baseline to Week 12 and Week 24 [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
  • Changes in fasting serum concentrations of lipids from baseline to Week 12 and Week 24 [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
  • Changes in summary measures derived from patient reported outcome questionnaires from baseline to Week 12 and Week 24 [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
  • Changes in individual item responses from patient reported outcome questionnaires from baseline to Week 12 and Week 24 [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
