The National Institutes of Health (NIH) is inviting applications for the Glioblastoma Therapeutics Network (GTN; U19 Clinical Trial Required), aimed at advancing research on novel therapies for adult glioblastoma (GBM). The initiative seeks to establish a collaborative network that will facilitate the development and clinical testing of innovative therapeutic agents capable of crossing the blood-brain barrier, thereby addressing a critical gap in GBM drug development. This funding opportunity, categorized as a discretionary cooperative agreement, does not require cost sharing and is open to a diverse range of eligible applicants, including tribal governments and community-based organizations. Interested parties should note that the estimated project start date is March 5, 2027, with applications due by May 27, 2026; for further inquiries, contact Dr. Suzanne Forry at 240-276-5922 or via email at forryscs@mail.nih.gov.
