Treatment of blast cell crisis of chronic myeloid leukemia with ICRF-159 (razoxane)

Abstract

Eleven patients with myeloid blast cell crisis and two patients with lymphoid blast cell crisis of chronic myeloid leukemia were treated with ICRF-159. Two of the patients with myeloid blast cell crisis achieved partial bone marrow remission and survived for 8+ and 18 months. One of the patients with lymphoid blast cell crisis reverted to the chronic phase of chronic myeloid leukemia after therapy with ICRF-159 in combination with prednisolone. The only significant toxic effect was myelosuppression.
