LONDON – Astrazeneca plc is broadening its antibody-drug conjugate (ADC) relationship with Daiichi Sankyo Co. Ltd. in a potential $6 billion development and commercialization deal. The two companies are to work together on DS-1062, Daiichi’s trophoblast antigen2 (TROP2) ADC, which is in phase I development in multiple tumors that express the cell surface glycoprotein. These include breast cancer and non-small-cell lung cancer (NSCLC), areas of strategic focus for Astrazeneca. The agreement builds on the March 2019 $6.9 billion pact between the two for Enhertu (trastuzumab deruxtecan), the HER2-targeted ADC now on course for blockbuster status, following FDA approval in December 2019 and U.S. launch at the start of the year.
DUBLIN – Tubulis GmbH raised €10.7 million (US$12.3 million) in a series A round to progress a next-generation antibody-drug conjugate (ADC) platform, which, it claims, will improve both the stability of ADC constructs and the efficiency with which they are generated.
