Gilead Sciences Inc. and Kymera Therapeutics Inc. have entered into an exclusive option and license agreement to accelerate the development and commercialization of a novel molecular glue degrader (MGD) program targeting cyclin-dependent kinase 2 (CDK2) with broad oncology treatment potential including in breast cancer and other solid tumors.

CDK2-directed MGDs are a new type of drug designed to remove CDK2 – a key contributor in tumor growth – rather than just inhibiting its function. Traditional inhibitors of CDK2 prevent it from working but often interfere with similar proteins, which can cause undesired side effects. MGDs have the potential to provide more precise, safe and effective treatments for cancers that rely on CDK2 activity by selectively removing this protein from cells.

“MGDs are opening exciting new possibilities in cancer research by offering a way to eliminate disease-driving proteins rather than just blocking them. This mechanism aligns within our oncology scientific framework where we evaluate therapeutic agents that selectively target and kill cancer cells with minimal impact on healthy tissue,” said Flavius Martin, MD, Executive Vice President, Research, Gilead Sciences. “We are delighted to partner with Kymera to advance this novel oral program with the potential to drive meaningful improvements in the standard of care for patients living with breast cancer and other cancers that are inadequately served with existing therapies.”

“We are excited to announce this strategic collaboration with Gilead Sciences, highlighting our dedication to innovation in the field with our first disclosed molecular glue program. We are committed to developing highly selective, potent, oral degrader medicines that address key disease-causing proteins and pathways that are undrugged or inadequately drugged by existing technologies,” said Nello Mainolfi, PhD, Founder, President and CEO, Kymera Therapeutics. “Our highly specific, orally active, CDK2 molecular glue degraders have demonstrated a compelling preclinical profile and have the potential to transform the therapeutic landscape for breast cancer patients and other tumor types with high unmet medical need.”
