Obesity Clinical Trial - Controlled Trial of WLS vs. CLI for Severely

Status Completed

Clinical Trial Summary

The goal of this study is to determine effective treatment and identify diagnostic biomarkers for Nonalcoholic steatohepatitis (NASH). Individuals that take part in the study will be participating in either a weight loss surgery (WLS) group or a comprehensive lifestyle intervention (CLI) group. People in the WLS group will receive vertical sleeve gastrectomy (VSG). The CLI group will receive dietary, activity and behavioral interventions provided by trained study staff.

Clinical Trial Description

The investigators have designed a rigorously controlled study designed to evaluate NASH outcomes in two parallel cohorts: 1) severely obese adolescents with NASH who have chosen to undergo WLS (specifically VSG) for clinical indications compared to 2) a control group of severely obese adolescents with NASH enrolled in a CLI offered as part of this study. The study will provide the best evidence to date of the effectiveness of WLS and CLI in treating NASH in adolescents with body mass index (BMI) ≥ 35 kg/m2. The investigators will also concurrently collect health-care utilization data to enable subsequent cost-effectiveness analyses (CEA) to evaluate the cost-effectiveness of WLS vs. CLI intervention in severely-obese adolescents with NASH. If the investigators' data support our hypothesis that WLS yields superior results, this will set the stage for randomized studies (if needed) and translational studies of weight loss-independent biological mechanism(s) unique to WLS, which may include specific changes in bile acid signaling and in the intestinal microbiome. The latter would facilitate developing novel pharmacotherapies accessible to younger or less obese children with NASH to whom WLS is not applicable. Cumulatively, this study has the potential to yield significant improvements in medical and quality of life (QOL) outcomes for a large proportion of pediatric patients with NASH and to reduce long term health care costs by identifying effective treatment options and decreasing progression to cirrhosis and end-stage liver disease. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
