Background on MDS and TELINTRA
MDS is a heterogeneous group of blood stem cell disorders of
increasing incidence. MDS is characterized by ineffective blood
cell production involving one or more of the red cell, white cell
or platelet lineages and with MDS patients having a variable risk
of progression to leukemia. There remains a need for effective,
well tolerated therapies for MDS having novel mechanisms of action.
TELINTRA has a novel mechanism of action that inhibits a target
enzyme called glutathione S- transferase P1-1 which in turn
facilitates the activation of JNK kinase, a key regulator of
cellular growth and differentiation of blood. TELINTRA has been
shown to stimulate normal multilineage differentiation of blood
stem cell precursors and induce cancer cell death in human leukemia
cell lines. Additional information on TELINTRA is available at
