Abstract
Combination of STI571, a tyrosine kinase inhibitor, with other drugs may be beneficial in the treatment of chronic myeloid leukaemia (CML). We measured the effects of STI571, AG490, farnesyltransferase inhibitor (FTI), interferon alpha (IFN-alpha), cytosine arabinoside (Ara-C) and all-trans retinoic acid (ATRA), singly and in combination, on clonogenic leukaemic cell proliferation. STI571, IFN-alpha and ATRA each reduced proliferation by 50-60%; AG490, FTI and Ara-C had less effect. Comparing the observed and expected (i.e. additive) effects of drug combinations showed STI571 + FTI, STI571 + AG490 and IFN-alpha + ATRA were additive; STI571 + IFN-alpha, IFN-alpha + Ara-C and STI571 + AG490 + FTI were less than additive. Thus, STI571 + FTI, STI571 + AG490 and IFN-alpha + ATRA may be better combination therapies for CML than STI571 + IFN-alpha, IFN-alpha + Ara-C or STI571 + AG490 + FTI.Entities:
