Bladder Cancer

The FDA has received a new drug application for&nbsp;erdafitinib as a treatment for&nbsp;patients with locally advanced or metastatic urothelial carcinoma and <em>FGFR</em> genetic alterations whose tumors progressed following chemotherapy,&nbsp;Janssen, the manufacturer of the oral pan-FGFR tyrosine kinase inhibitor, has announced.

In this letter from the editor, Targeted Therapies in Oncology Editor-in-Chief, Arjun V. Balar, MD, reflects on patient advocacy and those that support patients with cancer.&nbsp;

Until recently, therapeutic options for the management of advanced urothelial cancers have been limited to traditional cytotoxic agents with modest efficacy. However, the brisk pace of recent discovery in the field of immunotherapy and molecular therapeutics has ushered in a new era for management of patients with urothelial carcinoma.

The FDA has added PD-L1 status to the&nbsp;labels for pembrolizumab (Keytruda) and atezolizumab (Tecentriq) for existing frontline approvals for platinum-ineligible patients with urothelial carcinoma. The addition was made&nbsp;based on lower overall survival rates with the PD-1/PD-L1 inhibitors compared with platinum-based chemotherapy for patients with PD-L1&ndash;low expressing platinum-eligible urothelial carcinoma.

Arlene O. Siefker-Radtke, MD, professor of genitourinary medical oncology at MD Anderson Cancer Center, discusses the results presented at the 2018 ASCO Annual Meeting from a phase II cohort investigating erdafitinib in previously treated patients with urothelial cancer. Erdafitinib is a fibroblast growth factor receptor (FGFR) inhibitor that targets FGFR 1 through 4 and has previously shown promising activity.&nbsp;

According to a phase II study, over 40% of patients with metastatic or unresectable urothelial carcinoma responded to treatment with the investigational fibroblast growth factor receptor (FGFR) inhibitor erdafitinib. Findings from this study were presented at the 2018 ASCO Annual Meeting.

Sumanta K. Pal, MD, associate professor of the Department of Medical Oncology and Experimental Therapeutics at City of Hope, discusses the data he considers when treating patients with metastatic urothelial carcinoma.

Daniel P. Petrylak, MD, a professor of Medicine and Urology and co-director of the Signal Transduction Research Program at Yale School of Medicine, discussed results from the phase III RANGE trial for the combination of ramucirumab (Cyramza) and docetaxel in patients with urothelial carcinoma.
