  3. Percentage of Participants Who Achieve ≥15% Body Weight Reduction [ Time Frame: 72 Weeks ]
    Percentage of participants who achieve ≥15% body weight reduction

  4. Change from Randomization in Waist Circumference [ Time Frame: Randomization, 72 Weeks ]
    Change from randomization in waist circumference

  5. Change from Randomization in Body Weight [ Time Frame: Randomization, 72 Weeks ]
    Change from randomization in body weight

  6. Change from Randomization in Body Mass Index (BMI) [ Time Frame: Randomization, 72 Weeks ]

  18. Change from Randomization in Short Form 36 Version 2 Health Survey (SF 36v2) Acute Form Physical Functioning Domain Score [ Time Frame: Randomization, 72 Weeks ]
    The Short Form 36 Version 2 (SF-36v2) acute form, 1-week recall assesses participants' health-related quality of life (HRQoL) on 8 domains; 1) limitations in physical functioning due to health problems; 2) limitations in usual role because of physical health problems; 3) bodily pain; 4) general health perceptions; 5) vitality; 6) limitations in social functioning 7) limitations in usual role due to emotional problems; and 8) general mental health. Domain scores are norm-based and presented in the form of T-scores, with a mean of 50 and standard deviation of 10, with higher scores indicating better levels of function and/or better health.

  19. Change from Randomization in Impact of Weight on Quality of Life Lite Clinical Trials Version (IWQOL) Lite CT Physical Function Composite Score [ Time Frame: Randomization, 72 Weeks ]
    The IWQOL Lite-CT consists of 20 items, assessing 2 primary domains of obesity related HRQoL: Physical (7 items) and Psychosocial (13 items). A 5 item subset of the Physical domain - the Physical Function composite - is also supported. Items in the Physical Function composite describe physical impacts related to general and specific physical activities. Individual composite scale scores and a total score can be computed and are presented on a scale of 0 to 100, with higher scores indicating better function.

  20. Change from Baseline in Absolute Body Weight [ Time Frame: Baseline, 72 Weeks ]
    Change from baseline in absolute body weight

  21. Percent Change From Baseline in Body Weight [ Time Frame: Baseline, 72 Weeks ]
    Percent change from baseline in body weight

  22. Change from Baseline in BMI [ Time Frame: Baseline, 72 Weeks ]
    Change from baseline in BMI

  23. Change from Baseline in Waist Circumference [ Time Frame: Baseline, 72 Weeks ]
