Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This phase II trial compares the effect of erdafitinib alone to using the combination of erdafitinib and atezolizumab in treating patients with bladder cancer whose tumor invades the muscular bladder wall (muscle invasive)and who are ineligible for treatment with a chemotherapy drug called cisplatin. This trial also determines whether these treatment approaches are better than the usual approach for treating this type of cancer. The usual approach for treatment of someone with muscle invasive bladder cancer is chemotherapy with a drug called cisplatin followed by surgery (most common), or chemoradiation (radiation combined with chemotherapy) to the bladder (in some patients). However, half of the patients cannot get cisplatin due to safety concerns. This study has a screening step. The purpose of this step is to test patient's tumor to find out if it has a specific change (alteration) in the fibroblast growth factor receptor (FGFR) gene to determine patient's eligibility for this trial. Alteration of the FGFR gene causes bladder cancer cells to grow and divide abnormally. Erdafitinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal FGFR protein. This may help keep cancer cells from growing and may kill them. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving erdafitinib alone or in combination with atezolizumab may help to shrink tumor cells at the time of surgery better than the usual treatment in muscle invasive bladder cancer.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

PRIMARY OBJECTIVE:

I. To evaluate pathologic complete response (pCR) rates at radical cystectomy (RC) following neoadjuvant erdafitinib with or without atezolizumab in cisplatin-ineligible patients with muscle-invasive bladder cancer (MIBC) and susceptible FGFR3/2.

SECONDARY OBJECTIVES:

I. To determine the rate of pathologic downstaging (=\< pT1N0M0) among patients who receive RC.

II. To determine the clinical complete response (cCR) rate in patients who do not undergo planned RC.

III. To determine pCR + cCR. IV. To evaluate 2-year disease-free survival (DFS). V. To evaluate the overall survival (OS) rate at 2 years. VI. To evaluate the safety and tolerability of study treatment as well as surgical complications in the RC group.

EXPLORATORY OBJECTIVES:

I. To correlate the reduction of plasma circulating tumor deoxyribonucleic acid (DNA) (ctDNA) during study treatment and the surveillance period with disease outcomes (pCR and cCR, pathologic downstaging, 2-year DFS and OS).

II. To correlate tumor response with baseline tissue, ctDNA FGFR3/2 mutation status, and molecular signature.

III. To characterize the baseline tumor tissue immune profile of FGFR3/2-aberrant tumors including programmed death-ligand 1 (PD-L1) expression, tumor mutational burden (TMB), and T cell infiltration (PD-L1 expression, peripheral blood mononuclear cell (PBMC), T cell receptor \[TCR\] repertoire).

IV. To characterize the changes in the above tumor tissue immune profile following study treatment.

V. To correlate baseline tumor tissue TMB with disease outcomes (pCR and cCR, pathologic downstaging, 2-year DFS and OS).

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive erdafitinib orally (PO). Patients undergo collection of blood and computed tomography (CT)/magnetic resonance imaging (MRI) at various time points throughout the trial and colposcopy at baseline.

ARM II: Patients receive erdafitinib PO and atezolizumab intravenously (IV). Patients undergo collection of blood and CT/MRI at various time points throughout the trial and colposcopy at baseline.

* Patients requiring any medications or substances that are moderate CYP2C9 inducers and strong CYP3A4 inducers are ineligible. Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product
* Pregnant women are excluded from this study because erdafitinib is an FGFR inhibitor and atezolizumab is a monoclonal antibody with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with erdafitinib and atezolizumab, breastfeeding should be discontinued if the mother is treated with erdafitinib and atezolizumab
