She played a key role in the approval of Lemtrada, an infusion therapy for relapsing forms of multiple sclerosis, in North America and Europe, and was involved in the global approval of Mozobil, a medication for patients with non-Hodgkin’s lymphoma and multiple myeloma. Earlier in her career, Dr. Hanrahan worked at Boston Scientific Corporation (NYSE: BSX) as a medical writer supporting communications needs for clinical trials and registries in global markets.
