Trial Outcomes & Findings for Efficacy and Safety Trial to Evaluate the Effect of SCH 497079 on Weight in Obese and Overweight Participants (Study P05483)(COMPLETED) (NCT NCT00642993)

NCT ID: NCT00642993

Last Updated: 2018-09-10

Results Overview

Participant's body weight was measured in kilograms. For participants who discontinued during the study, last observation carried forward (LOCF) approach was applied to the analysis. any dropout before Week 12 was included in the analysis if the participant had a valid baseline and at least one post-baseline value.

PRIMARY outcome

Timeframe: Baseline and Week 12

Population: Intent-to-treat population consisted of all participants who received randomized treatment assignment and had the baseline body weight measurement and at least one post-baseline body weight measurement.

Participant's body weight was measured in kilograms. For participants who discontinued during the study, last observation carried forward (LOCF) approach was applied to the analysis. any dropout before Week 12 was included in the analysis if the participant had a valid baseline and at least one post-baseline value.

Timeframe: Baeline and Week 12

Population: Intent-to-treat population consisted of all participants who received randomized treatment assignment and had the baseline body weight measurement and at least one post-baseline body weight measurement.

For participants who discontinued during the study, LOCF approach was applied to the analysis. any dropout before Week 12 was included in the analysis if the participant had a valid baseline and at least one post-baseline value. Per protocol, participants were either obese (BMI ≥30 kg/m\^2 and ≤40 kg/m\^2) or overweight (BMI ≥27 kg/m\^2 and \<30 kg/m\^2) at enrollment.
