a Occurred in the period between the first dose and 30 days after the last dose.
b Infection includes bacterial, viral, fungal, and non-specified.
Serious adverse reactions were reported for 51% of patients. Serious adverse events reported for at least 5% of patients were bone marrow failure and thrombocytopenia (each 10%), and febrile neutropenia (6%). Serious adverse events of infections were reported for 8% of patients.
Deaths occurred while on study in five (5%) patients with CP CML. Two patients died due to cerebral hemorrhage, one due to multi-organ failure, one due to progression of disease, and one from unknown causes.
Accelerated Phase CML
Median total cycles of exposure was 2 (range 1 to 29), and the median total dose delivered during the trials was 70 mg/m2. The median duration of exposure for the 55 patients with accelerated phase CML was 1.9 months (range 0 to 30 months). Of the patients with accelerated phase CML, 86% received 14 days of treatment during cycle 1. By cycles 2 and 3, the percentage of patients receiving 14 days of treatment decreased to 55% and 44% respectively. Of the 40 patients who received at least 2 cycles of treatment, 27 (68%) had at least 1 cycle delay during the trials. The median number of days of cycle delays was greatest for cycle 3 (31 days) and cycle 8 (36 days).
