Mirum Pharmaceuticals Completes Acquisition of Bile Acid Product Portfolio for Treatment of Rare Liver Diseases from Travere Therapeutics

Mirum Pharmaceuticals, Inc. and Travere Therapeutics, Inc. announced the completion of Mirum’s previously announced acquisition of Travere’s bile acid product portfolio that includes Cholbam (cholic acid) and Chenodal (chenodiol), two medications addressing rare diseases in high-need settings (the “Asset Purchase”). In connection with the closing of the Asset Purchase, Travere received an upfront payment of $210 million from Mirum, and remains eligible to receive up to $235 million in potential sales-based milestone payments.

Mirum has acquired Travere’s rights to Cholbam, indicated for the treatment of bile acid synthesis disorders due to single enzyme deficiencies and adjunctive treatment of peroxisomal disorders in patients who show signs or symptoms of liver disease, and Chenodal, indicated for the treatment of radiolucent stones in the gallbladder, which is also under Phase 3 clinical evaluation for cerebrotendinous xanthomatosis (CTX). The closing of the Asset Purchase was subject to the satisfaction of customary closing conditions, including the expiration of the waiting period under the Hart-Scott-Rodino (HSR) Antitrust Improvements Act of 1976. In connection with the closing, Travere will provide certain transitional services to Mirum.

To support the acquisition, Mirum secured $210 million in funding from a syndicate of existing investors led by Frazier Life Sciences and other existing stockholders and new investors that include Avidity Partners, BVF Partners, Longitude Capital, Sofinnova Investments, Inc., and an undisclosed leading healthcare investment fund to finance the upfront payment for the acquisition.
