The goal of this clinical research study is to learn if LBH589 can help to control lower-risk (low or intermediate-1 risk) MDS. The safety of this drug will also be studied.
||Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
||Phase II Study of LBH589 for Patients With Low or Intermediate-1 Risk Myelodysplastic Syndrome
Primary Outcome Measures:
- Overall Response Rate Based on the Hematologic Improvement [ Time Frame: Assessment with 28-day cycle until response, then every 3 cycles as needed ]
Overall response rate defined by International Working Group (IWG) response criteria in myelodysplasia. Hematologic Improvement (HI) responses, at least 9 weeks: Erythroid response (pretreatment, <11 g/dL): Hgb increase by 1.5 g/dL; Relevant reduction units of Red blood cell (RBC) transfusions by absolute number at least 4 RBC transfusions/8 week compared with pretreatment transfusion number in previous 8 weeks; Only RBC transfusions for Hgb of 9.0 g/dL pretreatment count in RBC transfusion response evaluation; Platelet response (pretreatment,<100x10^9/L): If starting with >20x10^9/L platelets:
absolute increase 30x10^9/L, Increase from baseline <20 x10^9/L to >20x10^9/L and by =/> 100%; Neutrophil response (pretreatment, <1.0x10^9/L): =/> 100% increase & absolute increase >0.5x10^9/L; Progression or relapse after HI: At least 1 of the following: =/>50% decrement from max response levels in granulocytes or platelets; Reduction in Hgb by 1.5 g/dL; or Transfusion dependence .
