Developing transformative therapies to treat cancer

Founders Lonnie Moulder and Mary Lynne Hedley built Tesaro with abandoned assets from large pharma and biotech companies. Focused on oncology, the company has developed and launched two products: Varubi (for chemotherapy-induced nausea and vomiting) and Zejula (for ovarian cancer). Zejula extends the lives of ovarian cancer patients, preventing tumor recurrence. The company has additional oncology products in the pipeline.
