Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

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.

If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required * Breastfeeding females * History of active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs), known hepatitis B (defined as hepatitis B surface antigen \[HBsAg\] reactive), known active hepatitis C virus (defined as HCV ribonucleic acid \[mRNA\] \[qualitative\] is detected) or tuberculosis * History of active keratitis or corneal ulcerations * History of allogenic tissue/solid organ transplant * Congestive heart failure New York Heart Association Class 3 or 4, unstable angina pectoris, serious cardiac arrhythmias within 6 months prior to first dose of EV/pembrolizumab * Other uncontrolled current illness including, but not limited to, cardiac arrhythmia or psychiatric illness/social situations that would limit compliance with study requirements
