Bioequivalence Trial of Luitpold Azacitidine Versus Vidaza® in Patients With Myelodysplastic Syndrome, Myelofibrosis, Chronic Myeloid Leukemia or Chronic Lymphocytic Leukemia

Blinded Cross-over Bioequivalence Trial of Luitpold Azacitidine Versus Vidaza® in Patients With Myelodysplastic Syndrome, Myelofibrosis, Chronic Myeloid Leukemia or Chronic Lymphocytic Leukemia

The purpose of this study is to assess the bioequivalence of subcutaneous Vidaza® and subcutaneous Luitpold Azacitidine pharmacokinetics and to assess the comparative safety of subcutaneous Vidaza® versus subcutaneous Luitpold Azacitidine.

Study Overview
