Dr. Brosgart’s senior management experience in biotechnology and healthcare included Chief Medical Officer roles at Alios BioPharma and UCSF Benioff Children’s Hospital and Research Center and Vice President, Public Health and Policy at Gilead where she was responsible for the clinical development and approval of two antiviral therapies: Viread® for the treatment of HIV, and Hepsera® for the treatment of chronic hepatitis B.

Dr. Brosgart also serves in public policy through advocacy, advisory and board roles for numerous organizations and foundations, including the American Liver Foundation, the Hepatitis B Foundation, the San Francisco AIDS Foundation and Forum for Collaborative Research.

“I am thrilled to join Mirum at such a pivotal stage as it approaches the potential launch of maralixibat in Alagille syndrome,” said Carol L. Brosgart, M.D. “Mirum’s team, combined with its impressive pipeline, has tremendous potential to make a meaningful impact on the lives of patients and their families living with rare liver diseases.”
