SF-36 is a 36-item patient-reported survey of patient health that measures the participant's overall health-related quality of life (HRQoL). SF-36v2™ (acute version) questionnaire measured eight domains of functional health and well-being as well as two component summary scores (physical component summary (PCS) and mental component summary (MCS)). The 0-100 scale scores (where higher scores indicated a better HRQoL) from the SF-36 were converted to norm-based scores to enable a direct interpretation in relation to the distribution of the scores in the 2009 U.S. general population. In the metric of norm-based scores, 50 and 10 corresponds to the mean and standard deviation respectively of the 2009 U.S. general population. Change from baseline (week 0) in the domain scores and component summary (PCS and MCS) scores were evaluated at weeks 26, 52 and 78. A positive change score indicates an improvement since baseline. Results are based on the data from the in-trial observation period.

The Impact of Weight on Quality of Life Clinical Trials Version (IWQOL-Lite-CT) is designed to assess the impact of changes in weight on patients' quality of life within the context of clinical trials. The items of the IWQOL-Lite-CT pertain to physical functioning (physical, physical function and pain/discomfort) and psychosocial domains and all items employ a 5-point graded response scale (never, rarely, sometimes, usually, always; or not at all true, a little true, moderately true, mostly true, completely true). All IWQOL-Lite-CT composite scores range from 0 to 100, with higher scores reflecting better levels of functioning. Results are based on the data from the in-trial observation period, which was the time period from when a participant was randomised until the final scheduled visit, including any period after initiation of rescue medication and/or premature discontinuation of trial product.

Change from baseline (week 0) in Control of Eating Questionnaire (CoEQ) was evaluated at weeks (wk) 26, 52 and 78. The CoEQ comprised 19 items to assess the intensity and type of food cravings, as well as subjective sensation of appetite and mood, with the 4 domains: 'craving control' (items 9-12, 19), 'positive mood' (items 5-8), 'craving for savoury' (items 4, 16-18) and 'craving for sweet' (items 3, 13-15). The 19 items were scored on an 11-point graded response scale ranging from 10 to 0, with items relating to each of the 4 domains being averaged to create a final score. A low score in the domains 'craving for sweet and 'craving for savoury' represents a low level of craving; whereas a high score in the domains 'craving control' and 'positive mood' represents good control and a good mood, respectively. Results are based on the data from the in-trial observation period.
