  20. Change from Randomization in Short Form 36 Health Survey version 2 (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; 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.

  21. 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.

  22. Pharmacokinetics (PK): Steady State Area Under the Concentration Curve (AUC) of Tirzepatide [ Time Frame: Baseline through Week 72 ]
    PK: Steady State AUC of Tirzepatide
