This phase II trial tests how well the combination of futibatinib and durvalumab given before cystectomy works in treating patients with muscle-invasive bladder cancer (MIBC) who are ineligible for cisplatin-based therapy. Cisplatin-based therapy is the standard of care for patients with MIBC. However, many patients cannot receive standard therapy due to poor renal function, peripheral neuropathy, poor functional status, or clinically significant heart failure. Futibatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Durvalumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Radical cystectomy is a surgery to remove all of the bladder as well as nearby tissues and organs. Giving futibatinib in combination with durvalumab before surgery may be an effective treatment option for patients with MIBC who are ineligible for cisplatin-based therapy.
PRIMARY OBJECTIVE: I. Determine the pathologic complete response(pCR) rate of neoadjuvant combination futibatinib and durvalumab in patients with MIBC and fibroblast growth factor receptor (FGFR) overexpression. SECONDARY OBJECTIVES: I. Determine the safety of this neoadjuvant regimen. II. Assess the pathologic downstaging rate. III. Evaluate overall survival (OS) and progression free survival (PFS). IV. Evaluate delay in cystectomy. EXPLORATORY OBJECTIVES: I. Evaluate potential predictive biomarkers. II. Assess changes in the tumor microenvironment in pre- and post-treatment tumor sample…
