Privately-held US biotech firm Mersana Therapeutics and Japan’s Takeda Pharmaceutical (TYO: 4502) have entered a new strategic partnership granting Takeda rights to Mersana’s lead product candidate, XMT-1522, outside the USA and Canada.

The deal also expands an existing collaboration between the companies to provide Takeda with additional access to Mersana’s Fleximer antibody-drug conjugate (ADC) platform (The Pharma Letter January 13) and grants Mersana an option at the end of Phase I to co-develop and co-commercialize one of these programs in the USA. In addition, the companies will co-develop new payloads for use with ADCs.
