TESARO Submits New Drug Application for Intravenous Rolapitant to the U.S. Food and Drug Administration

WALTHAM, Mass., March 14, 2016 (GLOBE NEWSWIRE) — TESARO, Inc. (NASDAQ:TSRO), an oncology-focused biopharmaceutical company, today announced that it has submitted the New Drug Application (NDA) for an intravenous (IV) formulation of rolapitant to the U.S. Food and Drug Administration (FDA).

Rolapitant is a substance P/neurokinin-1 (NK-1) receptor antagonist that is marketed in tablet formulation by TESARO in the United States under the brand name VARUBI®. The FDA approved VARUBI on September 1, 2015, for use in combination with other antiemetic agents in adults, for the prevention of delayed nausea and vomiting associated with initial and repeat courses of emetogenic cancer chemotherapy, including, but not limited to, highly emetogenic chemotherapy.

“TESARO is committed to advancing new therapeutic options for patients with cancer, and the NDA submission for IV rolapitant represents a significant milestone for the Company,” said Mary Lynne Hedley, Ph.D., President and COO of TESARO. “By developing an intravenous formulation of rolapitant, our goal is to provide oncologists additional flexibility in their choice of antiemetic regimens.”

The NDA for IV rolapitant is supported by data from a clinical program that enrolled more than 400 subjects and included a bioequivalence study and several other supportive non-clinical and clinical studies. TESARO anticipates a standard 12-month review timeline for the IV rolapitant NDA.
