ABBV inks drug-discovery collaboration with (private) Tentarix: https://finance.yahoo.com/news/abbvie-tentarix-announce-collaboration-develop-130500277.html AbbVie and Tentarix Biotherapeutics today announced a multi-year collaboration focused on the discovery and development of conditionally-active, multi-specific biologic candidates in oncology and immunology. The collaboration will integrate AbbVie's expertise in oncology and immunology with Tentarix's proprietary Tentacles™ platform. Tentacles™ are multi-functional, conditionally-active antibody-based biologics that are designed specifically to activate immune cells that can modulate disease pathways, while potentially mitigating safety concerns associated with non-specific targeting of other immune cells. How are “tentacles” different from ADCs?
