HONG KONG – In less than a year, China-based Shanghai Miracogen Inc. has extended its partnership with Oss, the Netherlands based Synaffix BV for a second antibody-drug conjugate (ADCs) candidate. The new deal is similar to one signed last year in that it gives Miracogen nonexclusive rights to Synaffix’s Glycoconnect and Hydraspace ADC technologies for use in a second clinical candidate.
