Phase I Trial of 6-Hour Infusion of Glufosfamide, a New Alkylating Agent With Potentially Enhanced Selectivity for Tumors That Overexpress Transmembrane Glucose Transporters: A Study of the European Organization for Research and Treatment of Cancer Early Clinical Studies Group

Abstract

The principal toxicity of 6-hour infusion of glufosfamide is reversible renal tubular acidosis, the MTD is 6,000 mg/m(2), and the recommended phase II dose is 4, 500 mg/m(2). Close monitoring of serum potassium and creatinine levels is suggested for patients receiving glufosfamide for early detection of possible renal toxicity. Evidence of antitumor activity in resistant carcinomas warrants further clinical exploration of glufosfamide in phase II studies.
