Mersana Therapeutics and Merck KGaA announced an biotech partnering to collaboratively develop next-generation antibody-drug conjugates (ADCs) for $792 million.

ADCs are composed of an antibody linked to cytotoxic drugs, whereby the antibody specifically targets and delivers the cytotoxic drug to cancer cells, which could lead to higher drug levels at the tumor site.

Mersana and the biopharmaceutical division of Merck KGaA will leverage Mersana’s Fleximer technology to generate ADCs for multiple undisclosed targets.

Both parties have agreed to test a variety of ADCs by utilizing Mersana’s platform technologies and several cytotoxic agents as conjugates.

Merck KGaA will provide monoclonal antibodies to Mersana, which will generate the Fleximer-ADCs and conduct drug discovery and preclinical development activities.

Merck KGaA will be responsible for clinical development and commercialization of any products under an exclusive license from Mersana.

In addition to an upfront payment, Mersana is eligible to receive milestones plus royalties on worldwide net sales of products.
