"For patients diagnosed with urothelial cancer, outcomes are unfortunately disheartening due to the aggressiveness of the disease," said Peter Lebowitz, MD, PhD, Global Therapeutic Area Head, Oncology, Janssen Research & Development, LLC. "Through the continued development of erdafitinib, and working closely with the FDA, we look forward to bringing a potential new treatment option to patients."The Breakthrough Therapy Designation is based on data from a multicenter, open-label Phase 2 clinical trial evaluating the efficacy and safety of erdafitinib in the treatment of adult patients with locally advanced or metastatic urothelial cancer, whose tumors have certain fibroblast growth factor receptor (FGFR) genetic alterations. The Phase 2 study BLC2001 presented at the 2018 ASCO Genitourinary Cancers Symposium showed an overall response rate of 42 percent in 59 patients with relapsed/refractory metastatic urothelial cancer whose tumors harbored actionable FGFR mutations.
