Trial Outcomes & Findings for Study for Short Term Weight Loss in Candidates for Bariatric Surgery (NCT NCT00985491)

NCT ID: NCT00985491

Last Updated: 2016-09-15

Results Overview

Primary efficacy was assessment of the percent excess weight loss (%EWL) at Week 52 or last assessment. Excess weight was determined from ideal body weights based on a body mass index (BMI) of 25 kg/m2. Percent excess weight loss from baseline to 12 months was calculated as \[(baseline weight minus the 12-month weight) / (baseline weight minus the ideal body weight)\] \* 100).
