Mirum Pharmaceuticals’ Volixibat Study: A Potential Breakthrough for PBC Itching

Mirum Pharmaceuticals ((MIRM)) announced an update on their ongoing clinical study.

Study Overview: Mirum Pharmaceuticals is conducting a study titled A Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Efficacy and Safety of Volixibat in the Treatment of Cholestatic Pruritus in Patients With Primary Biliary Cholangitis. The study aims to assess the effectiveness and safety of volixibat in treating itching associated with Primary Biliary Cholangitis (PBC), a chronic liver disease. This research is significant as it could provide a new therapeutic option for managing symptoms and potentially impacting disease progression.

Intervention/Treatment: The study is testing volixibat, an oral drug administered twice daily. Volixibat is an Ileal Bile Acid Transporter (IBAT) inhibitor designed to alleviate itching in PBC patients. The study includes different dosages of volixibat and a placebo for comparison.

Study Design: This is a Phase 2 interventional study with a randomized, parallel assignment. It employs a double-blind approach, meaning both participants and investigators are unaware of who receives the actual drug versus the placebo. The primary purpose is treatment-focused, aiming to establish the drug’s efficacy and safety.

Study Timeline: The study began on September 9, 2021, with its latest update on October 8, 2025. These dates are crucial as they mark the study’s progression and ongoing recruitment status, indicating active research efforts.

Market Implications: The ongoing study could significantly impact Mirum Pharmaceuticals’ stock performance and investor sentiment. Positive results may enhance the company’s market position, especially if volixibat proves effective. Investors should watch for updates, as successful trials could influence the competitive landscape in treating PBC-related pruritus.

The study is currently recruiting, with further details available on the ClinicalTrials portal.
