Summary: This phase II ADC MATCH screening and multi-sub-study treatment trial is evaluating whether biomarker-directed treatment with one of three antibody-drug conjugates (ADCs) (sacituzumab govitecan, enfortumab vedotin, and trastuzumab deruxtecan) works in treating patients with solid tumor cancers that have high expression of the Trop-2, nectin-4, or HER2 proteins and that may have spread from where t...

Summary: This phase III trial compares the effectiveness of pembrolizumab and sacituzumab govitecan-hziy to standard of care in treating patients with urothelial cancer that has spread to nearby tissue or lymph nodes (locally advanced) or that has spread to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the ca...

Background: Rare tumors of the genitourinary (GU) tract can appear in the kidney, bladder, ureters, and penis. Rare tumors are difficult to study because there are not enough people to conduct large trials for new treatments. Two drugs-sacituzumab govitecan (SG) and atezolizumab-are each approved to treat other cancers. Researchers want to find out if the two drugs used together can help people with GU.
