Thomas Powles, MD, PhD, of Barts Health NHS Trust, Queen Mary University of London, and Jonathan E. Rosenberg, MD, of Memorial Sloan Kettering Cancer Center, discuss the 24-month findings from the phase III EV-301 trial, which suggest that enfortumab vedotin-ejfv continues to show a significant and consistent survival advantage over standard chemotherapy in patients with previously treated advanced urothelial carcinoma (Abstract 4516).
Sumanta K. Pal, MD, of City of Hope National Medical Center, discusses findings from the COSMIC-021 study, which showed that cabozantinib plus atezolizumab demonstrated encouraging clinical activity with manageable toxicity in patients with inoperable locally advanced or metastatic urothelial carcinoma. The combination was administered as first-line therapy in cisplatin-based chemotherapy–eligible and –ineligible patients and as second- or later-line treatment in those who received prior immune checkpoint inhibitors (Abstract 4504).
Shilpa Gupta, MD, of the Cleveland Clinic Foundation, discusses an updated consensus definition for standard therapy and clinical trial eligibility for patients with metastatic urothelial cancer who are platinum-ineligible, criteria that are proposed to guide treatment recommendations for this population. This may be especially important now that the U.S. Food and Drug Administration has restricted the use of first-line pembrolizumab to those who are considered platinum-ineligible (Abstract 4577).
Karim Chamie, MD, of the University of California, Los Angeles, discusses final clinical results on combining the superagonist N-803 with bacillus Calmette-Guérin (BCG) in patients whose carcinoma in situ and high-grade non–muscle-invasive bladder cancers are unresponsive to BCG alone. Of note, cystectomy was avoided in more than 90% of patients with 2 years of follow-up (Abstract 4508).
As reported in JAMA by Catto et al, the phase III iROC trial showed that robot-assisted radical cystectomy with intracorporeal urinary diversion resulted in better 90-day outcomes compared with open radical cystectomy in patients with bladder cancer. Study Details In the multicenter trial, 338...
Treatment with the anti–PD-1 therapy nivolumab after surgery helped reduce cancer recurrence in patients with urothelial cancer of the bladder or other sites in the urinary tract that had invaded the muscle and therefore posed a high risk for recurrence, according to clinical trial results...
The first bladder cancer drug targeting a cancer-driving gene mutation has been used relatively little despite its clear efficacy in a clinical trial, suggests a report published as a research letter by Nimgaonkar et al in JAMA Oncology.

In a small multi-institutional study, an artificial intelligence (AI)-based system improved providers’ assessments of whether patients with bladder cancer had complete response to chemotherapy before a radical cystectomy. These findings were published by Sun et al in Tomography. Yet the researchers ...
In the UK phase II NEOBLADE trial reported in The Lancet Oncology, Hussain et al found that the addition of nintedanib to neoadjuvant gemcitabine/cisplatin did not improve pathologic complete response rate in patients with locally advanced muscle-invasive bladder cancer. In the double-blind...
Thomas W. Flaig, MD, of the University of Colorado Cancer Center, discusses the rapidly changing treatment landscape for patients with bladder cancer, including PD-1 and PD-L1 inhibitors now approved for urothelial carcinoma; a category 1 indication for pembrolizumab in metastatic disease, post-platinum treatment and for non–muscle-invasive bladder cancer; enfortumab vedotin-ejfv for subsequent-line use; and erdafitinib for those with select FGFR mutations.
Guru P. Sonpavde, MD, Director of the Bladder Cancer Program at Dana-Farber Cancer Institute, Boston, said the therapeutic landscape of urothelial cancer has been altered by PD-L1 inhibitors and antibody-drug conjugates. “The rationale for Cohort 3 was based on high response rates seen with a...
