The complete remission (CR) rate was 31% (median CR duration of 3 months [range 2–28]) and the overall survival probability at 1 year was 10% (95%CI 4–16%). Responses were seen in B and T lineage diseases and in patients with adverse cytogenetics. Hematological and infectious grade >3 toxicities were found in 100 and 67% of the patients, respectively, with 7 (23%) treatment-related deaths. Other organ toxicities were infrequent. Clofarabine-based chemotherapy regimens might induce CRs in ALL and LL patients, but hematological toxicity and infections may limit their use in heavily pretreated patients.
