- Novel approaches to the development of genomic predictors of chemosensitivity that do not require clinical trials for their identification are urgently needed in order to identify agents that are clinically effective when either repurposed or discovered de novo specifically for urothelial carcinoma. Such repurposing of an FDA approved anticancer agent in order to advance therapy from one cancer to another would require only minimal clinical development, saving billions of dollars and reducing the time required to reach routine clinical practice.
