Brief summary
This Phase 2, double-blind, randomized, placebo-controlled, multicenter study, with an open-label long-term safety extension (LTSE), will evaluate the effect of Obeticholic Acid, and the subsequent addition of statin therapy, on lipoprotein metabolism in subjects with nonalcoholic steatohepatitis (NASH) with fibrosis stage 1 to 4, but no evidence of hepatic decompensation.
Interventions
Once a day (QD) by mouth (PO)
Initiate treatment with Atorvastatin at Week 4 visit with a dose of 10 mg once daily (QD) by mouth (PO). Increase Atorvastatin to 20 mg once daily (QD) by mouth (PO) at Week 8 visit if 10 mg daily is tolerated. Atorvastatin may be titrated up or down at Week 12 visit as clinically indicated.

Pre-assignment details
Subjects using statins within 30 days of the initial Screening visit (Screening Visit 1) are required to stop statin therapy immediately following this initial visit and must undergo a 4-week statin washout period prior to Screening Visit 2.
