• Commercial preparations are well underway in support of a potential oral rolapitant product launch in the fourth quarter of 2015.
• The rolapitant bioequivalence trial successfully achieved its primary endpoint, demonstrating similar exposure for a dose of intravenous (IV) rolapitant as compared to a dose of oral rolapitant.
• Expansion of the TESARO commercial organization is ongoing, with sales management, medical science liaison, and nurse educator teams now in place and the build-out of the field sales team is nearly complete in preparation for launch.
• TESARO and Jiangsu Hengrui Medicine Co., Ltd. announced an exclusive license agreement for the development, registration, manufacture, and commercialization of rolapitant in China.
• Phase 3 data from the NOVA trial of niraparib for patients with high-grade serous, platinum-sensitive, relapsed ovarian cancer is expected in the fourth quarter of 2015, following completion of enrollment in both cohorts earlier this year.
• Enrollment of the QUADRA trial of niraparib is ongoing for the treatment of patients with ovarian cancer who have received three or more prior lines of chemotherapy.
• TESARO and Merck announced a collaboration and have finalized the protocol to evaluate the combination of niraparib plus Merck’s anti-PD1 therapy, KEYTRUDA® (pembrolizumab) in a Phase 1/2 clinical trial in patients with triple-negative breast cancer or ovarian cancer.
• Patient enrollment continues in the Phase 3 BRAVO trial of niraparib for the treatment of patients with breast cancer, and planning is ongoing in support of the initiation of a trial of niraparib in the first-line ovarian cancer setting (PRIMA).
• The Phase 1/2 AVANOVA three-arm trial of niraparib, comparing the tolerability and efficacy of niraparib plus bevacizumab versus bevacizumab versus niraparib in patients with ovarian cancer, continues to enroll in collaboration with The European Network for Gynaecological Oncological Trial groups (ENGOT).
• Patient enrollment continues in the Phase 1 study of niraparib plus chemotherapy in patients with Ewing’s sarcoma in partnership with the Sarcoma Alliance for Research through Collaboration (SARC).
• The clinical activity of a fractionated dose of TSR-011 continues to be evaluated in ALK-positive patients who have not been previously treated with an ALK inhibitor, and a controlled release formulation is being evaluated within the ongoing Phase 1 study.
• Antibody drug candidates targeting PD-1, TIM-3, and LAG-3 continue to advance, and GLP toxicology studies are now underway for TSR-042.

Second-Quarter 2015 Financial Results

• TESARO reported a net loss of $60.6 million, or ($1.51) per share, for the second quarter of 2015, compared to a net loss of $37.1 million, or ($1.03) per share, for the second quarter of 2014.
• Research and development expenses increased to $38.9 million for the second quarter of 2015, compared to $30.6 million for the second quarter of 2014, driven primarily by higher costs related to expanded development activities and increased headcount.
• General and administrative expenses increased to $16.8 million for the second quarter of 2015, compared to $5.6 million for the second quarter of 2014, primarily due to pre-launch commercial activities in support of oral rolapitant, increased headcount, and higher professional service fees.
• In-process research and development expense was $1.0 million in the quarter and related to a development milestone achieved for our immuno-oncology programs, compared to $0.9 million for the second quarter of 2014, which related to initiation of patient treatment within the BRAVO trial of niraparib.
• Operating expenses, as described above, include total non-cash, stock-based compensation expense of $5.5 million for the second quarter of 2015, compared to $3.1 million for the second quarter of 2014.
• Net interest expense increased to $3.9 million for the second quarter of 2015, primarily due to the accrual of interest payable and non-cash amortization of the debt discount associated with the 3.00% senior convertible notes due 2021, issued in September 2014.
• As of June 30, 2015, TESARO had approximately $354.4 million in cash and cash equivalents and approximately 40.0 million outstanding shares of common stock. TESARO continues to expect cash utilization to increase over the course of 2015 and to average in the mid-$50 million range per quarter for the remainder of 2015, excluding a $15 million milestone payment that will be due upon first commercial sale of rolapitant, which is expected in the fourth quarter.
