Combination Study of Deferasirox and Erythropoietin in Patients With Low- and Int-1-risk Myelodysplastic Syndrome.

NCT01868477

Description:

The primary purpose of this trial was is to assess the effect of treatment with deferasirox combined with erythropoietin vs. erythropoietin alone on erythropoiesis in patients with low- and int-1-risk myelodysplastic syndrome. The addition of deferasirox to erythropoietin can lead to a potential synergism with the reduction of reactive oxygen species, through both the NF-kB pathway and the control of free toxic iron. This may create a better environment in the bone marrow for a better response with erythropoietin. This study was designed to test in a prospective way the combination of deferasirox with erythropoietin in terms of their effect on hematopoiesis.

Detailed Description

Trial Arms

NameTypeDescriptionInterventions
Erythropoietin alphaExperimentalPatients will receive erythropoietin 40,000 units/week. If after 4 weeks erythroid improvement is inadequate, dose will be escalated to 60,000 units/week. If after 12 weeks of treatment, erythroid improvement in inadequate, patients will be switched to the combination arm. At any time when erythroid response is achieved, erythropoietin treatment will be stopped until end of study.
  • Erythropoietin alpha
    Deferasirox + Erythropoietin alphaExperimentalPatients will receive deferasirox dispersible tablet (DT) 10 mg/kg/day or deferasirox film-coated tablet (FCT) 7 mg/kg/day in combination with erythropoietin 40,000 units/week. If after 4 weeks erythroid improvement is inadequate, erythropoietin dose will be escalated to 60,000 units/week. If after 12 weeks of treatment, erythroid improvement in inadequate, patients will be discontinued from the study. At any time when erythroid response is achieved, erythropoietin treatment will be stopped until end of study. Patients will continue deferasirox treatment.
