The National Institutes of Health (NIH) is inviting applications for Cancer Center Support Grants (CCSGs) aimed at enhancing cancer research within NCI-designated Cancer Centers. This funding opportunity, specifically the P30 Clinical Trial Optional grants, is designed to support both Comprehensive Cancer Centers and Cancer Centers that integrate various research disciplines, fostering a collaborative environment to advance understanding and treatment of cancer. The CCSGs are crucial for establishing a robust research infrastructure that promotes innovative cancer research initiatives across the United States, with applications subject to peer review and a maximum budget limit for new and renewal requests. Interested applicants can find more information and guidelines at the NIH website, and the application deadline is set for October 12, 2121.
