IV Vitamin C With Chemotherapy for Cisplatin Ineligible Bladder Cancer Patients: A Forgotten Group

University of Kansas Medical Center·interventional·Posted Aug 6, 2019·Updated Mar 25, 2025

In Brief

A Phase 2 clinical trial evaluating Ascorbic Acid for Bladder Cancer. Active but no longer recruiting, targeting 12 participants across 3 sites.

Detailed Summary

Bladder cancer is a common disease with high rates of mortality, especially at advanced stages. Neo-adjuvant cisplatin-based chemotherapy (NAC) followed by radical cystectomy is considered standard of care for patients with muscle invasive disease, as NAC improves surgical outcomes in these patients. However, some patients are ineligible for cisplatin-based chemotherapy due to other medical issues. Although a combination of carboplatin and gemcitabine has been used with limited success, most patients proceed directly to cystectomy without realizing the potential survival benefit afforded by NAC. Intravenous ascorbate (vitamin C) administration (IVC) has been shown to improve both carboplatin and gemcitabine-based therapy in other models. This trial will add IVC to gemcitabine/carboplatin chemotherapy to evaluate whether co-treatment will increase therapeutic efficacy.
