Collaboration to identify and advance best-in-class HPK1 protein degraders

Exclusive option for Cullinan to license related intellectual property from the collaboration

CAMBRIDGE, MA, USA I January 10, 2022 I Cullinan Oncology, Inc. (NASDAQ: CGEM) (“Cullinan”), a biopharmaceutical company focused on developing a diversified pipeline of targeted therapies for cancer patients, today announced the Company has entered into a collaboration agreement with the Icahn School of Medicine at Mount Sinai (“Icahn Mount Sinai”) to develop novel small molecule immune modulators.​

This exclusive option and multi-year collaboration agreement will be focused on the optimization and development of oral protein degraders targeting hematopoietic progenitor kinase 1 (HPK1), a key regulator of immune cell activation and a high-priority target in immune-oncology. The collaboration aims to accelerate the development of novel, best-in-class HPK1 degraders that stimulate robust anti-tumor immunity. The research will be conducted by leading scientists at both Cullinan and Icahn Mount Sinai. Cullinan will fund the collaboration and has an exclusive option to license the intellectual property for further development and commercialization.

The Icahn Mount Sinai team will be co-led by Steven J. Burakoff, M.D., Lillian and Henry M. Stratton Professor of Cancer Medicine, Dean for Cancer Innovation, and Chief, Pediatric Oncology at Icahn Mount Sinai, and Jian Jin, Ph.D., Mount Sinai Professor in Therapeutics Discovery and Director, Mount Sinai Center for Therapeutics Discovery, at Icahn Mount Sinai.

“Our team is excited to work with the talented and experienced cancer drug developers at Cullinan,” said Dr. Jin. “Our research has already demonstrated that a degrader approach to targeting HPK1 may control tumor growth more effectively compared to simply inhibiting HPK1 kinase activity. We believe this collaboration will help us identify novel, differentiated oral HPK1 degraders and can bring future benefit to cancer patients worldwide.”

“We are proud to partner with Icahn Mount Sinai, which is at the forefront of cancer research and patient care,” said Leigh Zawel, Chief Scientific Officer, Small Molecules, of Cullinan Oncology. “We are very excited to build on the synergy between the deep scientific expertise of the Icahn Mount Sinai team and the strong drug development capabilities at Cullinan to advance therapies that have the potential to significantly improve the lives of patients with cancer. We look forward to a fruitful collaboration in this novel area of science.”
