Trial Outcomes & Findings for Clofarabine Combinations in Relapsed/Refractory Acute Myeloid Leukemia (AML), Myelodysplastic Syndromes (MDS) and Myeloid Blast Phase Chronic Myeloid Leukemia (CML) (NCT NCT00067028)

NCT ID: NCT00067028

Last Updated: 2020-12-08

Results Overview

Response assessed by blood test or bone marrow aspirate following day 21 of induction and then every 2 weeks thereafter until remission or non-response. Complete remission (CR): Disappearance all clinical and/or radiologic evidence of disease; Neutrophil count \> 1.0 x10\^9/L and platelet count \>100x10\^9/L, and normal bone marrow differential (\< 5% blasts). Complete remission without platelet recovery (CRp): Peripheral blood and bone marrow results as for CR, but with platelet counts of \> 20 x 10\^9/L and \< 100 x 10\^9/L. Partial remission (PR): Peripheral blood count recovery as for CR, but with decrease in marrow blasts of \> 50% and not more than 6-25% abnormal cells in the marrow. All other responses considered as failures.

PRIMARY outcome

Timeframe: Up to 6 years

Population: Two participants in the Clofarabine + Idarubicin (CI) arm were not evaluable for response.

Response assessed by blood test or bone marrow aspirate following day 21 of induction and then every 2 weeks thereafter until remission or non-response. Complete remission (CR): Disappearance all clinical and/or radiologic evidence of disease; Neutrophil count \> 1.0 x10\^9/L and platelet count \>100x10\^9/L, and normal bone marrow differential (\< 5% blasts). Complete remission without platelet recovery (CRp): Peripheral blood and bone marrow results as for CR, but with platelet counts of \> 20 x 10\^9/L and \< 100 x 10\^9/L. Partial remission (PR): Peripheral blood count recovery as for CR, but with decrease in marrow blasts of \> 50% and not more than 6-25% abnormal cells in the marrow.
