NAFLD in T2DM: Prevalence in Hispanics and Role of Treatment
In Brief
A Phase 4 clinical trial evaluating pioglitazone-placebo, pioglitazone, and 2 other interventions for Nonalcoholic Steatohepatitis. Completed, enrolled 105 participants across 2 sites.
Detailed Summary
Nonalcoholic fatty liver disease (NAFLD) is a chronic liver condition frequently associated with type 2 diabetes (T2DM) and characterized by insulin resistance and hepatic fat accumulation. Liver fat may range from simple steatosis to severe steatohepatitis with necroinflammation and variable degrees of fibrosis (nonalcoholic steatohepatitis or NASH). Up to 40% of patients with NAFLD develop NASH in recent series. Risk factors for progression to NASH are unclear, but appears to be more common and progress more rapidly in older individuals, and in the presence of obesity and T2DM. Because the VA population in San Antonio, Texas, frequently combine these risk factors for NASH it was felt that a study targeting this very high-risk population was needed. This study will establish the long-term efficacy (primary endpoint: liver histology) and safety of pioglitazone for the treatment of VA patients with T2DM and NASH. All patients diagnosed with NASH will be offered lifestyle modification/weight loss (current standard of care) while being randomized to pioglitazone, vitamin E or placebo for up to 3 years. We believe that in such a high-risk population for complications from NASH, a substantial benefit may be expected from early detection and treatment. Specifically, the arms are: a) pioglitazone + vitamin E; b) vitamin E + placebo of pioglitazone; c) placebo of both. Patients are randomized to one of these 3 arms, and followed in a double-blind fashion for up to 18 months. Patients are then offered to continue into an open-label phase with pioglitazone + vitamin E or vitamin E alone for another 18 months.

Timeline
Interventions
This is a RCT in which all patients will be educated on a -500 kcal/day diet and a healthy lifestyle. Depending on randomization, subjects adjudicated to placebo will be started at the same time as the active (pioglitazone) arm following completion of the baseline measurements and continued on placebo for the rest of the clinical trial.
Pioglitazone will be started on 30 mg/day, titrated to the maximal dose (45 mg/day) at two months and continued at this dose for the rest of the clinical trial.
All participants will receive vitamin E 400 IU orally twice daily.
