Accelerate.EU, a collaborative European initiative, envisions revolutionising theranostics through innovative targeted alpha-therapies (TATs) using astatine-211. A unique consortium will combine diagnostics with potent cytotoxic effects of alpha-particles to enable precise tumour radiation while minimising side effects. Accelerate.EU's core objectives are: Innovate theranostic solutions based on therapeutic and diagnostic pairs for hard-to-treat cancers, exploring the potential for simultaneous preclinical studies and early-phase clinical trials (i.e. co-clinical approach) to showcase the enhanced benefits of these approaches for cancer patients. • Establish a robust and sustainable EU manufacturing and treatment infrastructure for astatine-211, ensuring compliance with quality assurance and regulatory guidelines while streamlining the supply chain across the EU. • Produce comprehensive educational and training content to support the deployment of theranostic solutions, fostering knowledge dissemination, transfer and longevity/durability Accelerate.EU strategically develop TATs to address unmet clinical needs in pancreatic, breast, and brain cancers. The co-clinical approach, incorporating concurrent clinical and preclinical studies, adds a breakthrough dimension to theranostics. Accelerate.EU pioneers 211At-theranostics establishing a resilient EU scale-up production network and empowering healthcare providers to offer TATs to cancer patients. Through the collaboration of experts from academia, industry and regulatory agencies, Accelerate.EU's implements a visionary approach addressing clinical gaps, accelerating TAT theranostic development, supporting EU global leadership, with primary target to improve patient outcomes for lasting impact on EU cancer care.
