Eisai Co., Ltd. and Bristol-Myers Squibb Company announced that the companies have entered into an exclusive global strategic collaboration agreement for the co-development and co-commercialization of MORAb-202, an antibody drug conjugate (ADC).
MORAb-202 is Eisai’s first ADC and combines Eisai’s anti-folate receptor alpha (FRα) antibody, and Eisai’s anticancer agent eribulin, using an enzyme cleavable linker. It is a potential best-in-class FRα ADC with a favorable pharmacology profile and demonstrated single agent activity in patients with advanced solid tumors.
Eisai is currently investigating MORAb-202 in FRα-positive solid tumors (inclusive of endometrial, ovarian, lung and breast cancers) in two studies: a Phase 1 clinical study in Japan and a Phase 1/2 clinical study in the United States. The companies are planning to move into the registrational stage of development as early as next year.
Bristol Myers Squibb will pay $650 million U.S. dollars to Eisai including $200 million U.S. dollars as payment toward Eisai research and development expenses. Eisai is also entitled to receive up to $2.45 billion U.S. dollars in potential future development, regulatory, and commercial milestones. The parties will share profits, r&d and commercialization costs in the collaboration territories and Bristol Myers Squibb will pay Eisai a royalty on sales outside of the collaboration territories. Eisai is expected to book sales of MORAb-202 in Japan, China, countries in the Asia-Pacific region, Europe and Russia. Bristol Myers Squibb is expected to book sales of MORAb-202 in the United States and Canada.
“MORAb-202 combines Eisai’s in-house discovered antibody and payload using the company's advanced chemistry capabilities,” said Haruo Naito, Chief Executive Officer at Eisai. “It is characterized by its payload of eribulin, which is a product of our modern synthetic organic chemistry that has already made contributions to patients with breast cancer and soft tissue sarcoma. Our collaboration with Bristol Myers Squibb will accelerate the development of MORAb-202 with the goal of bringing a potentially impactful treatment option to patients globally.”
