The study's primary objective is to determine the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) of Panobinostat when administered within 150 days after hematopoietic stem cell transplantation (HSCT) and given in conjunction with standard immunosuppressive therapy after HSCT for patients with high-risk Myelodysplastic Syndrome (MDS) or Acute Myeloid Leukemia (AML).
Secondary objectives are
The hypothesis of this study is that panobinostat can be an effective drug in preventing relapse of MDS and AML patients with high-risk features after hematopoietic stem cell transplantation with reduced-intensity conditioning (RIC-HSCT) while at the same time reducing graft-versus-host disease (GvHD) with preservation of graft-versus-leukemia (GvL) effect.
