January 25, 2018 updated by: H. Phillip Koeffler, Cedars-Sinai Medical Center

A Phase II Trial Of Paricalcitol In Myelodysplastic Syndromes

RATIONALE: Paricalcitol is a form of vitamin D that may help myelodysplastic cells develop into normal bone marrow cells.

PURPOSE: Phase II trial to study the effectiveness of paricalcitol in treating patients who have myelodysplastic syndrome.

Detailed Description

OBJECTIVES:

  • Determine the clinical effects of paricalcitol in patients with myelodysplastic syndromes.
  • Determine whether this drug can improve RBC, WBC, or platelet counts in these patients.
  • Determine whether this drug can decrease the risk of development of leukemia without causing undue toxicity in these patients.

OUTLINE: Patients receive oral paricalcitol daily for 4 months in the absence of disease progression or unacceptable toxicity.

Patients are followed at 1 month.

PROJECTED ACCRUAL: A total of 20 patients will be accrued for this study within 8 months.
