A Placebo-controlled Study of Volixibat in Subjects With Elevated Serum Bile Acids Associated With Intrahepatic Cholestasis of Pregnancy (OHANA) (OHANA)

February 3, 2023 updated by: Mirum Pharmaceuticals, Inc.

A Phase 2a/2b Randomized Double-Blind Placebo-Controlled Study to Evaluate the Efficacy and Safety of Volixibat in Adult Women With Intrahepatic Cholestasis of Pregnancy and Elevated Serum Bile Acid Concentrations (OHANA).

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.

Description

Inclusion Criteria:

  1. Female aged ≥18 and ≤45 years with a viable pregnancy.
  2. Provide signed informed consent as described in the protocol and willing to comply with all study visits and requirements.
  3. Diagnosis of ICP.
  4. (Part 2 only) Qualified level of pruritus associated with ICP, during screening.

Exclusion Criteria:

  2. Known non-reassuring fetal status based upon antepartum testing (e.g., NST/CTG or BPP) at or within 7 days before the baseline visit.
  3. Known fetal anomaly likely to result in intrauterine fetal demise or neonatal death within the first 30 days of life.
  4. Participating in another ongoing interventional clinical study at screening or planning to participate in another contemporaneous interventional clinical study while participating in this study.
