A cardiologist and internist by training, Dr. Somaratne’s career is defined by work on multiple pioneering clinical development programs, including the Hemophilia A gene therapy RoctavianⓇ, the development and global approvals of a PCSK9 inhibitor RepathaⓇ, and the development and approval of JournavxⓇ, the first NaV1.8 inhibitor approved for moderate to severe acute pain. He earned his Doctor of Medicine (MD) degree from Albany Medical College in Albany, NY, and also holds a Masters in Business Administration (MBA) from the University of North Carolina at Chapel Hill.
