Cardiovascular Safety Profile of Combretastatin A4 Phosphate in a Single-Dose Phase I Study in Patients with Advanced Cancer

Abstract

CA4P prolongs the QTc interval. There was a temporal relationship with the CA4P infusion and with ECG changes consistent with an acute coronary syndrome in two patients. It is advisable that future trials with CA4P have eligibility guidelines limiting patients with known coronary artery disease or those with multiple coronary artery disease risk factors until more experience is gained regarding potential cardiovascular toxicity with this agent.
