Brief Summary
The purpose of this study is to test a new medicine, vepugratinib, in comparison with placebo, to see if it is safe and can help people with a bladder cancer that is advanced or has spread.
Vepugratinib or placebo will be administered in combination with enfortumab vedotin and pembrolizumab.
Study participation could last up to approximately 6 years.
Protocol Interventions
Other: Placebo, Drug: EV, Drug: Pembrolizumab
Brief Summary
This is a phase 1 clinical trial to evaluate the safety, feasibility and immunogenicity of a personalized cancer vaccine strategy in patients with solid tumors and molecular residual disease. The hypothesis of the trial is that synthetic long peptide personalized cancer vaccines will be safe and capable of generating measurable neoantigen-specific T-cell responses enabling ctDNA clearance. The personalized cancer vaccines are composed of synthetic long peptides corresponding to prioritized cancer neoantigens and will be co-administered with poly-ICLC.
Protocol Interventions
Biological: Synthetic long peptide personalized cancer vaccine, Drug: Poly ICLC, Device: Signatera assay
Brief Summary
This phase II/III trial examines whether patients who have undergone surgical removal of bladder, kidney, ureter or urethra, but require an additional treatment called immunotherapy to help prevent their urinary tract (urothelial) cancer from coming back, can be identified by a blood test. Many types of tumors tend to lose cells or release different types of cellular products including their DNA which is referred to as circulating tumor DNA (ctDNA) into the bloodstream before changes can be seen on scans. Health care providers can measure the level of ctDNA in blood or other bodily fluids to determine which patients are at higher risk for disease progression or relapse. In this study, a blood test is used to measure ctDNA and see if there is still cancer somewhere in the body after surgery and if giving a treatment will help eliminate the cancer. Immunotherapy with monoclonal antibodies, such as nivolumab and relatlimab, can help the body’s immune system to attack the cancer, and can interfere with the ability of tumor cells to grow and spread. This trial may help doctors determine if ctDNA measurement in blood can better identify patients that need additional treatment, if treatment with nivolumab prolongs patients’ life and whether the additional immunotherapy treatment with relatlimab extends time without disease progression or prolongs life of urothelial cancer patients who have undergone surgical removal of their bladder, kidney, ureter or urethra.
Protocol Interventions
