Small cell lung cancer: Results of a phase II study of 1,2,4 triglycidylurazol

Abstract
Fourteen patients with small cell lung cancer (SCLC) received treatment with 1,2,4 triglycidylurazol (TGU) 600 mg/m2 or 800 mg/m2 as an IV bolus every 4 weeks. Twelve patients had received previous chemotherapy consisting of a five-drug regimen given for the short duration of only 9 weeks. All had measurable disease. Following TGU 11 patients had progressive disease and 3 patients had stable disease. The most frequent toxicity was nausea and vomiting, which occurred in all patients but was generally mild. Myelosuppression was common with a median white blood count nadir of 2.5×109/l (range 0.9–7.4×109/l) and median platelet count nadir of 76×109/l (range 5–173×109/l). Alopecia, thrombophlebitis, and hepatic or renal toxicity were not observed. In this study, TGU had no activity in SCLC, and the dose-limiting toxicity was myelosuppression.
