A Study of Darbepoetin Alfa in Patients With Myelodysplastic Syndrome (MDS)
Study Details
Study Description
Brief Summary
The primary objectives of the trial are to assess erythroid response to darbepoetin alfa, as determined by changes in hemoglobin and/or red blood cell (RBC) transfusion-dependence and to describe the safety profile of darbepoetin alfa in patients with MDS. The secondary objective is to assess bone marrow progenitor BFU-E growth before and after treatment with darbepoetin alfa.

Experimental: Darbepoetin alfa During the induction phase, the investigational agent DARBEPOETIN ALFA will be initiated at a dose of 4.5 ug/kg/week subcutaneously for 6 weeks. The dosage for the remaining treatment is dependent of patients response during the induction phase. |
Drug: Darbepoetin alfa
During the induction phase, the investigational agent DARBEPOETIN ALFA will be initiated at a dose of 4.5 ug/kg/week subcutaneously.If patients do not achieve a major erythroid response by 6 weeks, the dose of DARBEPOETIN ALFA will be doubled to 9.0 ug/kg/week.
