What are the two or three critical issues facing the field of cancer immunotherapy?
1. There are many critical regulatory topics concerning cellular therapies that need to be addressed. One of these is potency assays. Currently, as most potency assays for cellular therapy products do not align with clinical responses or onset of adverse events, the field needs clear and consistent guidance that includes available data to define rational and meaningful assays.
2. Developing cell therapy strategies for all solid tumors is another critical issue in the field of cancer immunotherapy. Recognizing the degree of heterogeneity for these diagnoses, this effort should include understanding the tumor microenvironment and the role of lymphodepletion, defining valid tumor targets, and enhancing the efficacy of cell therapy products.
