Phase II study of aziridinylbenzoquinone (AZQ: NSC-182986) in the treatment of malignant gliomas recurrent after radiation. Preliminary report.

Seventeen patients with malignant gliomas recurrent after chemotherapy and/or radiation failure were treated with aziridinylbenzoquinone (AZQ) at a dose of 20-15 mg/M2 weekly for four weeks followed by a two week rest. Regression of disease was observed in four patients, 4/17 (24%) for 35, 15+, 40+, and 10 weeks. Toxicity was limited to moderate reversible myelosuppression. AZQ in this dose and schedule has limited but definite activity in patients with malignant gliomas progressive after primary radiation therapy failure.
