WALTHAM, Mass., Feb. 28, 2017 (GLOBE NEWSWIRE) -- 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 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.”

Recent Business Highlights

• The U.S. launch of VARUBI^® continues, with sequential unit volume growth for the fourth quarter of 2016. For the month of December, VARUBI achieved greater than 40% market share in the oral NK-1 market in the U.S., which represents the market-leading position in the category.
• The European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) rendered a positive opinion for the marketing authorization application (MAA) for VARUBY^® for the prevention of delayed nausea and vomiting associated with highly and moderately emetogenic cancer chemotherapy in adults.
• In January, TESARO received a Complete Response Letter regarding the rolapitant IV New Drug Application (NDA) for the prevention of delayed nausea and vomiting associated with initial and repeat courses of emetogenic cancer chemotherapy. TESARO expects to be able to address the questions from the U.S. Food and Drug Administration (FDA) and resubmit the NDA to enable approval in the first half of 2017.
• The NDA for niraparib was accepted for review by the FDA for patients with recurrent ovarian cancer following response to platinum-based chemotherapy. The FDA granted priority review for the niraparib NDA and established a Prescription Drug User Fee Act (PDUFA) goal date of June 30, 2017.
• An expanded access program (EAP) for niraparib opened in the U.S. in January, through which niraparib is being made available for eligible women with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer following a complete or partial response to platinum-based chemotherapy. An EAP for niraparib is planned to open in Europe in the first half of 2017, and will be initiated on a country-by-country basis.
• Enrollment continues in the Phase 3 PRIMA trial of niraparib for patients with first-line ovarian cancer, the Phase 3 BRAVO trial for patients with germline BRCA-mutated, metastatic breast cancer, and in the QUADRA trial of niraparib for the treatment of patients with ovarian cancer who have received three or more prior lines of chemotherapy.
• Based upon the anti-tumor activity observed in Phase 1 of the TOPACIO trial of niraparib plus KEYTRUDA^® (pembrolizumab) in patients with ovarian cancer or with triple negative breast cancer, the trial has expanded to Phase 2 and is enrolling patients. Initial data are expected at an upcoming medical meeting.
• Following the presentation of data at ASCO in 2016, the Phase 2 portion of the AVANOVA trial of niraparib plus bevacizumab in patients with ovarian cancer continues to enroll, and updated data are expected in 2H 2017.
• Dose escalation and identification of a fixed dose and schedule was completed for the Phase 1 trial of TSR-042, an anti-PD-1 antibody candidate, and a registration trial is planned to begin in 1H 2017.
• Enrollment continues in the Phase 1 dose escalation study of TSR-022, an anti-TIM-3 antibody candidate.
• A lead PD-1/LAG-3 bi-specific antibody candidate was identified.

Selling, general and administrative expenses increased to $158.6 million for 2016, compared to $78.7 million for 2015, primarily due to increased headcount, commercial and pre-launch activities in support of VARUBI and niraparib, expansion of the European commercial organization, and higher professional service fees.
