A total of 65 patients under the age of 55 with acute leukaemia received high-dose cytosine arabinoside (Ara-C) in combination with high-dose etoposide without an anthracycline. Complete remission rates for patients with relapsed or refractory acute myelogenous leukaemia (AML) were 15/25 (60%) and 1

β¦ Synopsis
Clofarabine (40Β mg/m^2^/dayβΓβ5) and high-dose cytosine arabinoside (Ara-C, 1β2Β g/m^2^/dayβΓβ5) were used in 10 men and 11 women, at a median age of 45 (22β62)βyears, with refractory (Nβ=β4) and relapsed (Nβ=β17) acute myeloid leukaemia, after a median of 3 (2β5) prior regimens. Grade 4 myelosuppression was observed in all cases, with two patients dying of bacterial sepsis. Nine patients achieved a complete remission. Disease status, number of prior therapies, and cytogenetic aberrations were not associated with the outcome. However, remission was only achieved with Ara-C at 2Β g/m^2^/day and not 1Β g/m^2^/day (9/15 versus 0/4, Pβ=β0.03).

Twenty-five adult patients with refractory acute lymphocytic leukemia received salvage therapy with mitoxantrone 5 mg/m2 intravenously over 1 hour daily for 5 days and cytosine arabinoside 3 g/m2 intravenously over 2 hours every 12 hours for six doses. Overall, nine patients (36%) achieved complete
## Abstract Clofarabine is a second generation nucleoside analogue. It inhibits DNA repair and activates the mitochondrial apoptotic pathway leading to cell death. __In vitro__ clofarabine has demonstrated synergy with daunorubicin and AraβC and in phase II clinical trials has shown promising activ
