Clinical Trials Designed To Block Autophagy In Multiple Cancers Show Promise

PHILADELPHIA— In the largest group of results to date, researchers from Penn Medicine's Abramson Cancer Center and other institutions have shown in clinical trials that the malaria drug hydroxychloroquine (HCQ) blocked autophagy in a host of aggressive cancers—glioblastoma, melanoma, lymphoma and myeloma, renal and colon cancers—and in some cases helped stabilize disease. Autophagy—an essential process cancer cells need to fuel their growth—is a key troublemaker spurring tumor growth. Block this pathway, many preclinical studies suggest, and anti-cancer agents such as chemotherapy and radiation therapy will be able to do their job better. read more
