Metastatic Bladder Carcinoma

This phase II trial studies how well cabozantinib works in combination with nivolumab and ipilimumab in treating patients with rare genitourinary (GU) tumors that has spread from where it first started (primary site) to other places in the body. Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cabozantinib, nivolumab, and ipilimumab may work better in treating patients with genitourinary tumors that have no treatment options compared to giving cabozantinib, nivolumab, or ipilimumab alone.

This clinical trial evaluates the impact of an education and navigation support tool (ENST) on patient and caregiver participation in care coordination for bladder cancer that has spread to nearby tissue or lymph nodes (locally advanced), to other places in the body (metastatic) or that cannot be removed by surgery (unresectable). Patients with advanced bladder cancer tend to be older, have multiple medical conditions and often have poor access to health care. An ENST may be an effective method to improve participation in treatment decision-making and care planning among patients with locally advanced, metastatic and unresectable bladder cancer and their caregivers.

This phase II trial tests how well enfortumab vedotin (EV) and pembrolizumab works in treating patients with bladder cancer of variant histology (a group of less common types of bladder cancer) that have spread to nearby tissue or lymph nodes (locally advanced) or that has spread from where it first started (primary site) to other places in the body (metastatic). Enfortumab vedotin is a monoclonal antibody, enfortumab, linked to an anticancer drug called vedotin. Enfortumab attaches to a protein called nectin-4 on cancer cells in a targeted way and delivers vedotin to kill them. It is a type of antibody-drug conjugate. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving enfortumab vedotin and pembrolizumab may kill more tumor cells in patients with locally advanced or metastatic bladder cancer of variant histology.
