Intravenous Ascorbate Plus Gemcitabine/Carboplatin: A Novel and Cost-Effective Alternative With Evident Efficacy in Patients With Muscle Invasive Bladder Cancer
University of Kansas Medical Center
Summary
This is a phase II, single arm, Simon two-stage design, trial, enrolling patients with cisplatin ineligible MIBC and/or those patients who decline cisplatin based NAC. Assess rates of pathologic downstaging and quality of life in MIBC cisplatin-ineligible/declined patients when IVC is added to gemcitabine-carboplatin NAC.
Description
The investigator has hypothesized adding IVC to carbo/gem NAC will enhance pathological downstaging and improve QOL. The patients eligible for this study (cisplatin ineligible or declined with MIBC) typically proceed straight to cystectomy within 12 weeks of initial diagnosis. In this study, participants will receive two cycles of gemcitabine/carboplatin, along with IVC and then proceed to cystectomy.
