Advanced Urothelial Cancer

The purpose of this study is to evaluate the safety and tolerability of an investigational drug called GB-4362 when it is given together with enfortumab vedotin and pembrolizumab in adults with advanced or metastatic urothelial cancer. GB-4362 is a monoclonal antibody designed to bind and neutralize free monomethyl auristatin E (MMAE), a chemotherapy payload released from enfortumab vedotin that is associated with side effects such as peripheral neuropathy.

The goal of this study is to evaluate the feasibility and preliminary efficacy of a combined acupuncture and exercise intervention for the management of chemotherapy-induced peripheral neuropathy (CIPN) in participants with metastatic bladder cancer receiving enfortumab vedotin (EV) and pembrolizumab (Pembro). The names of the two study groups in this research study are: * Acupuncture + Virtual Exercise (AVE) * Virtual Exercise Only (VE)

International study that will evaluate the association of prespecified biomarkers with resistance to Antibody-drug conjugates (ADCs), a type of targeted cancer treatment currently used in clinical practice for treating different tumor types.
