Nivolumab plus ipilimumab added to standard of care chemotherapy did not improve outcomes as 1st line therapy for unresectable or metastatic bladder cancers with PD-L1 expression > 1%.

In this 15-minute CME activity, two experts provide a rundown of multiple disease factors to consider, evolving clinical trial data, and the various therapeutic options available in the second and subsequent lines of therapy for patients with locally advanced or metastatic urothelial carcinoma.

Combining BCG with N-803 “results in significant complete response rates and long-term disease-free rates without significant systemic side effects,” reported lead study investigator Sam S. Chang, MD, of Vanderbilt University Medical Center. N-803 is a high affinity, interleukin 15 immunostimulatory fusion protein that promotes the proliferation and activation of natural killer cells and CD8+ T cells without binding to regulatory T cells. Its use in this phase two/three study including 83 patients with CIS and 77 with papillary NMIBC. In the CIS group, the complete response rate was 71% with a median duration of response of 23.6 months. NMIBC group had 12- and 24-month disease-free survival (DFS) rates of 57% and 48%, respectively. The median DFS was 23.6 months. In both groups, cystectomy was avoided in more than 90% of patients.

As a TROP-2-directed antibody-drug conjugate with an SN-38 payload that has shown preliminary activity in metastatic urothelial carcinoma (mUC), sacituzumab govitecan (SG) – brand name Trodelvy –was evaluated and compared to current treatments to gauge whether SG objective response rates (ORRs) and median overall survival (OS) outperform the average of 10% ORR and 7 to 8 months OS.  

This new indication marks the second FDA approval for sacituzumab govitecan (Trodelvy, Immunomedics) and was based on the phase 2, single-arm TROPHY-U-01 main efficacy endpoints in objective response rate (ORR) and duration of response (DOR). With a relative 5-year survival rate of 5.5%, this is a significant advancement for patients with metastatic urothelial cancer (mUC), the most common type of bladder cancer.
