-  TESARO to Receive $100 Million Upfront Payment and is Eligible for Future Regulatory and Commercial Milestones, Plus Royalties

WALTHAM, Mass. and OSAKA, Japan, July 27, 2017 (GLOBE NEWSWIRE) -- TESARO, Inc. (NASDAQ:TSRO) and Takeda Pharmaceutical Company Limited (TSE:4502) today announced an exclusive licensing agreement for the commercialization and clinical development of niraparib, a novel poly ADP-ribose polymerase (PARP) inhibitor. This agreement includes the development of niraparib for the treatment of all tumor types in Japan, and all tumor types excluding prostate cancer in South Korea, Taiwan, Russia and Australia. Niraparib, first marketed in the U.S. in April under the brand name ZEJULA(TM), has quickly become the most frequently prescribed PARP inhibitor in the U.S.    

Under the terms of this agreement, TESARO will receive a $100 million upfront payment and is eligible to receive additional milestone payments of up to $240 million related to the achievement of certain regulatory and commercial goals.  TESARO will also be eligible to receive from Takeda tiered royalties based on a double digit percentage of net product sales. Takeda gains exclusive commercial rights for all potential future niraparib indications in Japan, and rights excluding prostate cancer in South Korea, Taiwan, Russia and Australia. Takeda will be responsible for development of niraparib in Japan and the four specified countries, including all associated expenses. Additional terms of this agreement were not disclosed.

"The niraparib development program addresses many of the most prevalent and devastating cancers worldwide. We must continue to make new treatments available to patients and, through research, further our knowledge into the full utility of this molecule," said Christophe Bianchi, President of Takeda Oncology. "We are pleased to be collaborating with TESARO, a company we admire for its high caliber oncology expertise. This agreement represents another step in our goal of building Takeda's robust portfolio in solid tumors and, more importantly, our commitment to patients living with cancer who desperately want - and need - new, innovative therapies."

Once-daily niraparib is the first and only PARP inhibitor that has received approval for the maintenance treatment of women with recurrent ovarian cancer, regardless of BRCA  mutation or biomarker status. TESARO's development plan currently includes clinical trials of niraparib in patients with ovarian, breast, and lung cancer. Janssen Biotech has licensed rights to develop and commercialize niraparib specifically for patients with prostate cancer worldwide, except in Japan.

"TESARO is devoted to providing transformative therapies for people bravely facing cancer, and this partnership enables us to continue to globalize our mission," said Mary Lynne Hedley, Ph.D., President and COO of TESARO. "As the largest pharmaceutical company in Japan, Takeda is recognized as a leader in oncology, and we are excited to work with the Takeda team to quickly advance niraparib for patients who are in need of new treatment options."

Niraparib is not currently approved for use in Japan, South Korea, Russia, Taiwan or Australia.                               

About ZEJULA (Niraparib)
ZEJULA (niraparib) is a poly(ADP-ribose) polymerase (PARP) inhibitor indicated for the maintenance treatment of adult patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in a complete or partial response to platinum-based chemotherapy.  In preclinical studies, ZEJULA concentrates in the tumor relative to plasma, delivering greater than 90% durable inhibition of PARP 1/2 and a persistent antitumor effect. Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML), including some fatal cases, was reported in patients treated with ZEJULA. Discontinue ZEJULA if MDS/AML is confirmed.  Hematologic adverse reactions (thrombocytopenia, anemia and neutropenia), as well as cardiovascular effects (hypertension and hypertensive crisis) have been reported in patients treated with ZEJULA. Monitor complete blood counts to detect hematologic adverse reactions, as well as to detect cardiovascular disorders, during treatment.  ZEJULA can cause fetal harm and females of reproductive potential should use effective contraception.
