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

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.

About this study

This study did not meet the original enrollment objective of 60 patients and was terminated without extending enrollment past original planned LPFV of 31-Oct-2016.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Key Inclusion Criteria:

  • Patients who had low- and Int-1-risk myelodysplastic syndrome
  • Documented diagnosis of the following:

Myelodysplastic syndrome that lasted ≥ 3 months and < 3 years Disease must not have been secondary to treatment with radiotherapy, chemotherapy, and/or immunotherapy for malignant or autoimmune diseases

  • A hemoglobin < 10 g/dL and ≥ 8 g/dL
  • History of transfusions < 10 RBC units and must not have been RBC transfusion dependent
  • 300 ng/mL < serum ferritin < 1,500 ng/mL (Values within 10% difference above 1500 ng/ml or 10% difference below 300 ng/ml could have been accepted at the investigator's discretion.
  • Endogenous erythropoietin levels < 500 units/L
  • Serum creatinine ≤ 1.5 times upper limit of normal (ULN)
  • Creatinine clearance above the concentration limit in locally approved prescribing information (PI). Patients with creatinine clearance between 40 and less than 60 mL/min, who did not present with additional risk factors that might impair renal function, were eligible at the discretion of the investigator

Key Exclusion Criteria:

  • Patients who had MDS with isolated del(5q)

  • Patients who had received steroids or immunosuppressive therapy for the improvement of hematological parameters (stable steroid treatment for adrenal failure or chronic medical conditions, and intermittent dexamethasone as antiemetics were allowed).
  • B12 and folate deficient patients with and without clinical symptoms (patients were rescreened after successful therapy of B12 and folate deficiency)
  • Uncontrolled seizures or uncontrolled hypertension

Primary outcomes

  1. Difference in Percentage of Patients Achieving Erythroid Response Within 12 Weeks, by Treatment Group (Full Analysis Set)

    Time frame: Baseline up to 12 weeks

    Difference in percentage of patients achieving an erythroid response within 12 weeks of treatment between the two arms according to modified IWG 2006 criteria increase in hemoglobin (Hb) ≥ 1.5 g/dL. Erythroid response is defined as the increase in Hb from baseline ≥ 1.5 g/dL. Patients achieving erythroid response at least once within 12 weeks were considered responders

Secondary outcomes

  1. Absolute Change From Baseline to Post-baseline Value for Hemoglobin(g/dL)(Full Analysis Set)

    Time frame: Baseline up to 24 weeks

    Hematological response criteria defined as: Erythroid response: hemoglobin (Hb) increase from baseline >= 1.5 g/dL (baseline < 11 g/dL), neutrophil response: increase from baseline >= 100% and increase > 0.5 × 10^9/L (baseline <1 × 10^9/L), platelet response: increase from baseline >= 30 × 10^9/L (baseline <100 × 10^9/L) according to modified IWG 2006 criteria

  2. Summary of Hematologic Improvement in Patients Randomized to EPO+DFX and EPO Alone, Within 24 Weeks of Treatment (Full Analysis Set)

    Time frame: Baseline up to 24 weeks

    Percentage of participants achieving an hematologic improvement defined as: neutrophil improvement: increase from baseline >0.5 × 10^9/L (baseline = 1.0 × 10^9/L ), platelet improvement: increase from baseline ≥ 30 × 10^9/L (baseline = 100 × 10^9/L), hemoglobin improvement: Hb increase from baseline ≥ 1 g/dL (baseline<11 g/dL)

  3. Absolute Change in Hemoglobin Values up to 24 Weeks

    Time frame: Baseline up to 24 weeks
