The Dutch biotech, Synaffix BV has secured a deal in China that expands the use of its conjugation technology for antibody-drug conjugates (ADC), while generating income of up to $125 million. Announced on 10 April, the agreement will give Shanghai Miracogen Inc non-exclusive rights to two of Synaffix’s proprietary technologies. One is a conjugation technology that exploits the native glycan for the attachment of a toxic payload to an antibody; the other uses polar spacer technology to link the antibody to a cargo.
