The quianazoline antifolate N10-propargyl-5,8-dideazafolic acid (ICI 155,387), an inhibitor of thymidylate synthetase (TS), was evaluated for clinical toxicity in a phase I trial. The compound was given once every week as a bolus injection. Fourteen patients with advanced cancer were treated at doses of 10-30 mg/m3. Four patients from the lowest to the highest dose developed severe renal toxicity, detected by a reversible decrease in the Cr-EDTA clearance. Hepatotoxicity was observed with transient elevations of alanine aminotransferase (ALT) in 10 patients and alkaline phosphatase in nine patients. Neither the incidence nor the severity of these toxicities was dose related. Two patients developed feelings of fatigue, which in one patient coincided with a decrease in Cr-EDTA clearance. No myelotoxicity, dermatological, gastrointestinal toxicity or mucositis was seen. No tumour responses due to ICI 155,387 occurred. The severity and the erratic nature of the renal side-effects suggest that this schedule cannot be recommended for further development of this compound in Phase II trials.
