WALTHAM, Mass., Feb. 28, 2017 — TESARO, Inc. (NASDAQ:TSRO), an oncology-focused biopharmaceutical company, today reported operating results for fourth-quarter 2016 and provided an update on the Company’s development programs.


“2017 is poised to be an eventful year for TESARO as we prepare for four product launches across the United States and Europe,” said Lonnie Moulder, CEO of TESARO. “2016 was an important year for the Company, highlighted by the landmark NOVA trial results for niraparib, which were published in the New England Journal of Medicine and presented in a presidential session at the European Society of Medical Oncology annual meeting. We intend to build upon these successes in 2017 with the planned launch of niraparib in the U.S. during the first half of this year and in Europe by year end. Looking beyond ovarian and breast cancer, we aim to finalize and initiate our registration program for niraparib in lung cancer in the first half of this year. Lastly, we are excited about the progress in our immuno-oncology pipeline, and expect to initiate a registrational program for TSR-042 in the coming months.”
