Cardiovascular Outcomes Study of Naltrexone SR/Bupropion SR in Overweight and Obese Subjects With Cardiovascular Risk Factors (The Light Study)
A Multicenter, Randomized, Double-Blind, Placebo-Controlled Study Assessing the Occurrence of Major Adverse Cardiovascular Events (MACE) in Overweight and Obese Subjects With Cardiovascular Risk Factors Receiving Naltrexone SR/Bupropion SR

The purpose of this study is to determine the effects of NB relative to placebo on major adverse cardiovascular events (MACE) such as cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke in overweight and obese subjects who are at a higher risk of having these events because they have diabetes and/or other cardiovascular risk factors.
