Wednesday, March 20, 2024 Notification of the permanent trial closure of REC3 (SWOG S1500) A Randomized, Phase II Efficacy Assessment of Multiple MET Kinase Inhibitors (Cabozantinib, Crizotinib, Savolitinib, and Sunitinib) in Metastatic Papillary Renal Carcinoma (PAPMET) trial. This randomized phase II trial studied how well cabozantinib s-malate, crizotinib, savolitinib, or sunitinib malate work in treating patients with kidney cancer that has spread from where it started to nearby tissue or lymph nodes or to other places in the body. Cabozantinib s-malate, crizotinib, savolitinib, and sunitinib malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
