Twenty-four patients with acute leukemia or blast crisis (BC) of chronic myelocytic leukemia (CML) in relapse or refractory to standard chemotherapy, were eligible for treatment with mitoxantrone. Mitoxantrone (Novantrone; dihydroxyanthracenedione) was administered in a dose of 8-13 mg/m2 on five consecutive days. Five of 20 evaluable patients were induced into complete remission, one patient achieved a partial remission. Side-effects included moderate to severe bone marrow suppression, moderate mucositis and hair loss. No cardiotoxicity was observed. We believe that mitoxantrone is an active agent in the treatment of acute leukemia and suggest further studies in combination chemotherapy.

Mitoxantrone (Novantrone; 1, 4-dihydroxy-5, 8-bis [[2-[(2-hydroxyethyl) amino]ethyl]amino-] 9, 10 anthracenedione dihydrochloride (NSC 301739] is a synthetic anthracenedione with intercalating properties. Activity has been shown in preclinical studies in mice bearing intraperitoneal P388 and L1210 leukaemias, ADJ-Pc6 plasmacytoma and a variety of solid tumours. In a phase I/II collaborative study fourteen consecutive patients with relapsed or primarily refractory acute leukaemia received a single infusion of mitoxantrone (20-32 mg/m2) at fourteen-day intervals. Antileukaemic activity was seen but there were no complete remissions and toxicity was minimal. Mitoxantrone was subsequently given in a five-day schedule at a dose of 10mg/m2 daily to twenty-one patients with relapsed or refractory acute leukaemia or chronic myeloid leukaemia in blast crisis (CML-BC). Four of five patients in first relapse of acute non-lymphoblastic leukaemia (ANLL) achieved a complete remission (CR). The overall response rate (CR + partial remission (PR] was 48%. In an ongoing phase III study the same (5-day) mitoxantrone treatment has been given in conjunction with a 7-day continuous infusion of cytosine arabinoside (Ara-C) in a kinetically designed schedule based upon the preclinical studies of the Mount Sinai group.

Forty-seven patients with poor-prognosis myeloid leukemias received induction therapy with high-dose cytosine arabinoside (HDara-C), 1.5-3.0g/m2 for 8-10 doses, and mitoxantrone (DHAD), 12-15 mg/m2 for 3 doses. Complete remissions were achieved in 21 [45%, 95% confidence interval (CI) 30.2-59.9%] of the patients, including 11 of 14 with acute myelogenous leukemia (AML) in first relapse (79%, 95% CI 49.2-95.3%), 4 of 8 with refractory anemia with excess blasts in transformation (RAEBiT) (50%, 95% CI 15.4-84.6%), and 4 of 6 (67%, 95% CI 22.3-95.7%) previously untreated elderly AML patients. Patients with secondary AML and advanced chronic myelogenous leukemia had a very low response rate. The incidence of reversible toxicity was low and only 3 treatment-related deaths occurred. After reinduction, 8 of 9 AML patients < or = 60 years of age were ultimately able to undergo intensive therapy and either autologous 4-hydroperoxycyclophosphamide-purged bone marrow (7 patients) or peripheral blood stem cell (1 patient) transplantation with satisfactory hematological recovery. We conclude that HDara-C and DHAD is an effective antileukemic regimen in selected AML and RAEBiT patients, and that its use may allow subsequent successful autologous BMT in appropriate patients.
