Futibatinib in Combination With Durvalumab Prior to Cystectomy for the Treatment of Muscle-Invasive Bladder Cancer Patients Who Are Ineligible for Cisplatin-based Therapy

Description

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 samples in participants.

OUTLINE:

Patients receive futibatinib orally (PO) once daily (QD) on days 1-28 and durvalumab intravenously (IV) over 60 minutes on day 1 of each cycle. Treatment repeats every 28 days for up to 3 cycles in the absence of disease progression or unacceptable toxicity. Patients then undergo radical cystectomy within 4-12 weeks. Patients also undergo computed tomography (CT) and magnetic resonance imaging (MRI) during screening and on the trial and also undergo blood sample collection on the trial.

After completion of study treatment, patients are followed up at 30 days, and then every 3 months for 2 years.
