Study Summary

The purpose of this clinical trial is to learn about the safety and effects of the study medicine (called PF-06882961) for the potential treatment of obesity. The study will compare the experiences of participants taking the study medicine (PF-06882961) to those of participants who take placebo (a look- alike substance that contains no active study medicine). The aim is to measure the body's response to the study medicine, including any changes in participants' body weight, waist and hip measurements, how well they tolerate the study medicine, and to measure levels of the study medicine in participants' blood. This study is seeking participants who have obesity, who do not have diabetes and who have had a stable body weight and not participated in a formal weight loss program in the 90 days before the study. The study medicine or placebo will be taken as tablets by mouth 2 times a day (1 time in the morning and 1 time in the evening). There are 3 groups of participants (called cohorts) in this study. For participants in Cohorts 1 and 2, total study participation will be about 9 months, with 15 planned study visits (14 visits to the study clinic and 1 telephone call). For participants in Cohort 3, total study participation will be about 10 months, with 21 planned study visits (12 visits to the study clinic and 9 telephone calls).

Primary Outcome

Percent change from baseline in body weight at end of treatment was reported in this outcome measure. Analysis was performed using MMRM with treatment, time, strata (females versus males) and treatment-by-time interaction as fixed effects, natural log-transformed baseline as a covariate and the (natural log-transformed baseline)-by-time interaction with time fitted as a repeated effect and participant as a random effect. Values were back-transformed from the log scale. Percent change = 100 multi
