These findings suggest that early administration of these drugs could protect cognitive function and reduce neuroinflammation in patients post-radiation.\n\nThis prospective phase II clinical trial will assess the combined efficacy of Memantine and Pioglitazone in improving cognitive outcomes and preventing RIBI without adversely impacting the anti-tumor efficacy of radiation therapy. The study will also explore the synergistic effects of these two FDA-approved drugs in early-stage RIBI prevention, providing a new therapeutic strategy for enhancing the quality of life in cancer patients receiving radiotherapy.",[27,28,29],"Radiation Disease","Cognitive Impairment","Drug Effect",[31,32,33,34],"radiation induced brain injury","Memantine","Pioglitazone","cognitive function","NOT_YET_RECRUITING","2024-09-16",{"date":38,"type":39},"2024-09-19","ACTUAL",{"date":41,"type":21},"2024-09-10",{"date":43,"type":21},"2027-06-30",{"name":45,"class":46},"Affiliated Cancer Hospital & Institute of Guangzhou Medical University","OTHER"]
