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.
HONG KONG - South Korean biopharma Legochem Biosciences Inc. has partnered with the U.K.’s Iksuda Therapeutics Ltd. to develop oncological antibody-drug conjugates (ADC). Under the global research collaboration and license agreement, Legochem is set to rake in up to $407 million from development, regulatory and commercial milestone payments, as well as royalties on the sales of any resulting ADC products.
DUBLIN – Immunomedics Inc. is stopping the phase III Ascent trial of its antibody-drug conjugate, sacituzumab govitecan, in triple-negative breast cancer (TNBC) on the unanimous recommendation of the study’s independent data safety monitoring committee, after a scheduled look at the study data uncovered what the company called “compelling efficacy.”
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.
Albuquerque, N.M.-based Agilvax Inc. CEO Joseph Patti told BioWorld that his firm’s antibody-drug conjugate (ADC) method uses “the same linkers, same payloads” as other firms but the “unique factor for us is the target we’re going after” – SLC7A11 (xCT), an amino acid transporter implicated in the metabolic redox activities of metastatic cancer cells.
