Article Title: Synergistic antiproliferative effect of interferon alpha and azidothymidine in chronic myelogenous leukemia
Abstract: The possible synergistic interaction between azidothymidine (AZT) and interferon alpha (rIFN-alpha-2a) in the treatment of chronic myelogenous leukemia (CML) was studied in vitro using marrow or peripheral blood hematopoietic progenitors from 10 patients with CML in the mixed (CFU-GEMM) colony culture assay. Used singly, either agent inhibited erythroid (BFU-E) and granulocyte-macrophage (CFU-GM) CML hematopoietic progenitor proliferation in a dose-dependent fashion, with the inhibitory effect being more pronounced on BFU-E than on CFU-GM colony-forming cells. The combination of both drugs in therapeutic concentrations exerted a significant synergistic inhibition on CML stem cells as assessed by the median-effect principle and isobologram equation analysis. A suboptimal dose of AZT (0.5-mu-mol/1) synergistically augmented the effect of rIFN-alpha-2a whereas an inactive dose of 10 U/ml rIFN-alpha-2a similarly enhanced the CML stem cell growth inhibition exerted by AZT. Our data indicate that AZT may augment the already established therapeutic benefits of IFN-alpha in CML.
