"2015 was an extraordinary year for TESARO, as we obtained FDA approval for and launched our first product, VARUBI, in the United States, and we look forward to bringing VARUBI to additional patients in 2016," said Lonnie Moulder, CEO of TESARO. "We are entering 2016 in a strong position and anticipate the achievement of multiple milestones with our pipeline, including the availability of the first pivotal data from our niraparib clinical programs and the initiation of clinical trials for our immuno-oncology antibody candidates. We are confident that we have a significant opportunity to build meaningful shareholder value as we continue to execute on our mission of providing transformative therapies to people bravely facing cancer."
VARUBI (Rolapitant)
VARUBI is a selective and competitive antagonist of human substance P/neurokinin-1 (NK-1) receptors. TESARO launched VARUBI in late November of 2015, following FDA approval 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 anticipates achieving the following milestones related to VARUBI in 2016:
Continue to execute on the VARUBI commercial launch in the United States;
Submit the NDA for intravenous (IV) rolapitant in Q1; and
Submit the oral rolapitant Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) in Q2.
Niraparib Franchise
Niraparib is a potent, oral PARP inhibitor that is currently being evaluated in three ongoing pivotal trials. TESARO is building a robust niraparib franchise by assessing activity across multiple tumor types and by evaluating several potential combinations of niraparib with other therapeutics. The ongoing development program for niraparib includes a Phase 3 trial in patients with ovarian cancer (the NOVA trial), a registrational Phase 2 treatment trial in patients with ovarian cancer (the QUADRA trial), and a Phase 3 trial for the treatment of patients with BRCA-positive breast cancer (the BRAVO trial). In addition, a Phase 3 trial of niraparib in first-line ovarian cancer (PRIMA) and a Phase 1/2 clinical trial designed to evaluate the combination of niraparib plus KEYTRUDA (pembrolizumab) in patients with triple-negative breast cancer or ovarian cancer are slated to begin during the first quarter. Several collaborator-sponsored studies are also underway, including combination trials of niraparib plus enzalutamide, bevacizumab, and temozolomide, in patients with prostate cancer, ovarian cancer, and Ewing’s sarcoma, respectively.
Patient treatment continues in the Phase 3 NOVA trial, and based upon the most recently observed event rate, TESARO continues to expect data to be available in the second quarter of 2016. Enrollment of the QUADRA trial of niraparib for the treatment of patients with ovarian cancer who have received three or more prior lines of chemotherapy continues, and initial response rate data from this trial is anticipated to become available in the second quarter. A niraparib NDA submission is planned for the second half of 2016.
TESARO anticipates completing the following milestones related to niraparib in 2016:
Initiate patient enrollment in the Phase 3 clinical trial of niraparib in first-line ovarian cancer (PRIMA) in Q1;
Initiate patient enrollment in the niraparib/KEYTRUDA (pembrolizumab) combination trial in Q1;
Report data from the Phase 3 NOVA trial and from the QUADRA trial of niraparib in Q2;
Submit the NDA for niraparib in 2H; and
Continue to enroll the Phase 3 BRAVO trial of niraparib in breast cancer patients with germline BRCA mutations throughout 2016.
Immuno-Oncology Portfolio
TESARO’s antibody drug candidates targeting PD-1, TIM-3, and LAG-3 continue to advance, and the Investigational New Drug (IND) application for TSR-042, our anti-PD-1 antibody candidate, has been submitted to the U.S. Food and Drug Administration (FDA).
TESARO anticipates completing the following milestones related to its immuno-oncology portfolio in 2016:
Initiate a Phase 1 clinical trial of TSR-042 in Q1;
Submit the IND for TSR-022 (anti-TIM-3 antibody) in Q2;
Select a clinical candidate targeting LAG-3 in 1H 2016;
Identify a dose and schedule for TSR-042 by YE 2016; and
Select bispecific clinical candidates targeting PD-1/TIM-3 and PD-1/LAG-3 in 2016.
Year-End 2015 Cash Position
TESARO ended 2015 with approximately $230 million in cash and cash equivalents (unaudited).
About VARUBI
VARUBI is a substance P/neurokinin-1 (NK-1) receptor antagonist indicated 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. VARUBI is contraindicated in patients receiving thioridazine, a CYP2D6 substrate. The inhibitory effect of a single dose of VARUBI on CYP2D6 lasts at least seven days and may last longer. Avoid use of pimozide; monitor for adverse events if concomitant use with other CYP2D6 substrates with a narrow therapeutic index cannot be avoided. Please see full prescribing information, including additional important safety information, available at www.varubirx.com.
An intravenous formulation of rolapitant is also being developed. TESARO licensed exclusive rights for the development, manufacture, commercialization, and distribution of VARUBI (rolapitant) from OPKO Health, Inc.
