Details and patient eligibility


The purpose of this study is to evaluate the efficacy of sorafenib in patients with Myelodysplastic Syndrome (MDS). Eligible subjects will receive Sorafenib administered at 400mg orally twice a day, given on days 1-28 of a 28-day cycle. Patients will be evaluated for hematological response after 2 cycles and then every 3 cycles thereafter for a maximum of 5 years from study entry. If a patient achieves a complete response they may receive an additional 6 cycles of therapy beyond documentation of complete response unless unacceptable toxicity occurs. For patients with partial response, hematological improvement or stable disease they will continue treatment until relapse, progression of disease, or unacceptable toxicity occurs.

  • History of leukemia (having more than 20% blasts in blood or marrow)
  • Current treatment with coumadin, heparin and its derivatives.
  • Major surgery (including needle biopsy of visceral organs) for 1-month prior to study and fully recovered. In addition, no placement of a subcutaneous or tunneled venous access device for 3 days prior to study and adequately healed.
  • Significant cardiac or vascular events within 6 months: acute MI, unstable angina, severe peripheral vascular disease (ischemic pain at rest class 3 or worse, non-healing ulcers/wounds, congestive heart failure (NHYA class ≥ 2), uncontrolled cardiac arrhythmias, and disseminated intravascular coagulation.
  • No use of hematopoetic growth factors within 4 weeks of starting sorafenib.
  • Known severe hypersensitivity to Sorafenib or any component of the formulation.
  • Caution should be exercised with the concomitant use of other CYP3A4 inducers, such as rifampin, St. John's Wort, phenytoin, phenobarbital and dexamethasone.
  • Uncontrolled hypertension with a systolic blood pressure greater than 160 or a diastolic blood pressure greater than 100 despite treatment.
