A Placebo-controlled Study of Volixibat in Subjects With Elevated Serum Bile Acids Associated With Intrahepatic Cholestasis of Pregnancy (OHANA)
Purpose
This is a two-part randomized study of volixibat in patients with Intrahepatic Cholestasis of Pregnancy (ICP) and elevated serum bile acid concentrations (sBA). Part 1 is an open-label study to evaluate safety and tolerability of two doses of volixibat. Part 2 is a double-blind, placebo controlled, study designed to evaluate the safety and efficacy of a selected volixibat dose.

Exclusion Criteria
- At the time of either the screening or baseline visit, decision has already been made to deliver within the next 7 days, for any indication. 2.
