DS-5010 is a highly selective and potent RET (ret proto-oncogene) kinase inhibitor in late preclinical development. RET rearrangements and activating mutations are associated with several types of cancer, including non-small cell lung cancer, colorectal cancer and thyroid cancer.1,2,3
Under the terms of the agreement, Daiichi Sankyo grants Boston Pharmaceuticals worldwide rights for the research, development, manufacturing and commercialization of DS-5010. Daiichi Sankyo will collaborate with Boston Pharmaceuticals to complete preclinical studies to support an Investigational New Drug Application to regulatory authorities and initiation of the clinical program, after which Boston Pharmaceuticals will be responsible for all activities related to DS-5010. Daiichi Sankyo will receive an upfront payment and is eligible for clinical, regulatory and sales milestone payments, as well as royalties on net sales worldwide. Financial terms of the agreement were not disclosed.
“We continue to actively prioritize and manage our growing oncology portfolio to ensure that promising compounds are supported with appropriate resources, either within Daiichi Sankyo Cancer Enterprise or through strategic licensing agreements and partnerships,” said Antoine Yver, MD, MSc, Executive Vice President and Global Head, Oncology Research and Development, Daiichi Sankyo. “It’s our obligation to bring innovative compounds to patients with cancer as quickly as possible, and we believe this agreement with an innovative U.S. partner will rapidly advance the development of this novel compound and potentially its availability to patients. Boston Pharmaceuticals has worked hard to develop a model that works for potential partners. We congratulate them on this success and look forward to continuing to explore similar collaborations in the future.”
“The acquisition of DS-5010, now the fifth candidate in our pipeline, demonstrates our commitment to identifying and developing novel and differentiated therapeutic agents through strategic partnerships for the ultimate benefit of patients,” said Robert Armstrong, PhD, Chief Executive Officer and Co-Founder of Boston Pharmaceuticals. “This agreement, with such an innovative partner as Daiichi Sankyo, marks a significant step in our plan to assemble a diverse portfolio of clinical candidates across a broad range of mechanisms and therapeutic targets.”
About Daiichi Sankyo Cancer Enterprise
The vision of Daiichi Sankyo Cancer Enterprise is to leverage our world-class, innovative science and push beyond traditional thinking in order to create meaningful treatments for patients with cancer. We are dedicated to transforming science into value for patients, and this sense of obligation informs everything we do. Anchored by our Antibody Drug Conjugate (ADC) and Acute Myeloid Leukemia (AML) Franchises, our cancer pipeline includes more than 20 small molecules, monoclonal antibodies and ADCs stemming from our powerful research engines: our two laboratories for biologic/immuno-oncology and small molecules in Japan, and Plexxikon Inc., our small molecule structure-guided R&D center in Berkeley, CA. Compounds in development include: quizartinib, an oral FLT3 inhibitor, for newly-diagnosed and relapsed or refractory AML with FLT3-ITD mutations; DS-8201, an ADC for HER2-expressing breast and gastric cancer, and other HER2-expressing solid tumors; and pexidartinib, an oral CSF-1R inhibitor, for tenosynovial giant cell tumor (TGCT), which is also being explored in a range of solid tumors in combination with the anti-PD1 immunotherapy pembrolizumab.
