Brief summary
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 * To determine safety and tolerability of panobinostat * To determine overall and disease-free survival at 12 months after HSCT * To evaluate immunoregulatory properties of panobinostat * To evaluate patient-reported health-related quality of life (HRQL) 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.

Inclusion criteria
* AML (except acute promyelocytic leukemia, AML M3) with high-risk features defined as one or more of the following criteria: * refractory to or relapsed after at least one cycle of standard chemotherapy * \> 10% bone marrow blasts at day 15 of the first induction cycle * adverse risk cytogenetics including complex karyotype (≥ 3 abnormalities or abnormalities of chromosomes 3, 5 or 7) regardless of stage * secondary to MDS or radio-/chemotherapy or * MDS RAEB according to the WHO classification or intermediate-2 or high-risk according to IPSS or * Chronic myelomonocytic leukemia (CMML) with ≥ 5% bone marrow blasts and * Allogeneic HSCT with reduced intensity conditioning (see Section 15.1 for definition) performed within 60 - 150 days prior to study entry * Complete hematologic remission documented by bone marrow aspiration within 28 days prior to study entry
Exclusion criteria
* Active acute GvHD overall grade 2 - 4 * Prior treatment with a deacetylase (DAC) inhibitor * Patients with impaired cardiac function or other concurrent severe and/or uncontrolled medical conditions * Clinical symptoms suggesting central nervous system (CNS) leukemia * Patient has an impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of oral panobinostat
