Targeted protein degraders: a call for collective action to advance safety assessment

Targeted protein degraders (TPDs) are emerging classes of therapeutics that have the potential to address difficult drug targets in new ways. In 2021, experts convened to discuss challenges in TPD safety evaluation, and supported supplementing individual efforts to address these challenges with collective development of novel decision frameworks, tools and a shared evidence base.

Targeted protein degraders (TPDs) — including molecular glues and heterobifunctional molecules — are rapidly evolving classes of drugs that are being investigated to treat cancer and other diseases1. They are characterized by use of endogenous protein degradation processes to target previously ‘undruggable’ proteins, as well as established drug targets in new ways.
