[A phase II study with high-dose cytarabine (NS-075) in adult patients with relapsed and refractory acute leukemia].
A multi-center phase II clinical study with high dose cytarabine (NS-075) was conducted in adult patients with relapsed and/or refractory acute leukemia. 2 g/m2 cytarabine was given 12 times by 3-hour intravenous infusion every 12 hrs. 46 patients were registered, and 44 were evaluable: 35 with acute myeloid leukemia (AML) and 9 with acute lymphoblastic leukemia (ALL). There were 28 males and 16 females, with a median age of 37.5 years (range 15-68), including 6 of more than 60 years. Among 35 patients with AML, there were 16 (45.7%) complete and 2 (5.7%) partial remissions. Among 9 patients with ALL, there were 2 (22.2%) complete and 1 (11.1%) partial remissions. The major non-hematologic toxicities were gastrointestinal symptoms such as nausea/vomiting, anorexia and diarrhea, as well as fever, infection, conjunctivitis, alopecia, hepatic and renal dysfunctions. Central nervous system (CNS) toxicity was mild and reversible. Therapy-related death occurred in 5 patients resulting from prolonged pancytopenia, which suggests the necessity of strict countermeasures for infections as well as good patient care. These results indicate that high-dose cytarabine is a promising therapy for treatment of relapsed and/or refractory acute leukemia.
