Overall Summary Particularly prevalent in Texas, renal cell carcinoma (RCC) is lethal when metastatic. To address this unmet medical need, the UTSW Kidney Cancer SPORE has developed a comprehensive therapeutic program in proven (targeted therapies and immunotherapy) and innovative (metabolism-directed) areas. Arguably, the most important driver of RCC is HIF2α. Discovered at UTSW, and regarded as undruggable, structural studies revealed a vulnerability that was exploited through a chemical screen leading to the founding of Peloton Therapeutics in the UTSW BioCenter and the development of PT2385 and PT2977. During the previous funding period, Project 1 investigators validated HIF2α as a target, identified putative biomarkers of dependency, executed a phase 1 trial, identified resistance mutations, and established HIF2α as a core dependency. Culminating the vertical collaboration and program success, Peloton was acquired by Merck, and PT2977 (also called belzutifan) gained FDA approval. During the next period, an innovative siRNA-based, second-generation inhibitor targeting both wild-type and resistant mutant HIF2α will be co-developed together with a ground- breaking imaging radiotracer enabling HIF2α evaluation in patients. Project 2 investigators exploit a profound link between RCC and metabolism. Using pioneering isotope-labeled nutrient infusions, Project 3 investigators established during years 1-5 that glutamine is a key nutrient fueling RCC growth in patients. In years 7-12, they will deploy the authenticated In Vivo Metabolism Lab to target glutamine bypass pathways, likely explaining the recent failure of glutaminase inhibitors. Finally, by leveraging Breakthrough Prize-recognized research at UTSW leading to a new innate immune system-activating drug, Project 3 investigators propose a paradigm shift in immunotherapy development involving the coordinated activation of the adaptive and innate arms (as it occurs physiologically). Together with previously commended development and career-enhancing programs, SPORE investigators are supported by four Cores. A forward-looking Administrative Core (Core A) serves as a hub. A Pathology Core (Core B) brings to bear one of the largest and most sophisticated RCC tumor banks and expertise supporting national efforts. A Data Analytics Core (Core C) assists with statistical support, bioinformatics, and data management with an avant-garde tool that automatically extracts information from the electronic medical record, self-updates, and links this information to experimental genomics and the tumor bank. An Imaging Core (Core D) delivers enabling technologies, including IND-holding innovative tracers, and unqualified expertise. Building upon the Simmons Comprehensive Cancer Center Kidney Cancer Program and its history of collaborative, interdisciplinary cancer research, SPORE Projects and Cores provide an engine of discovery, innovation, and translation supporting national and international efforts to advance patient care, research, and education.
