Eligibility Criteria
Inclusion Criteria:

- Ability to provide written informed consent, obtained prior to participation in the study and any related procedures being performed
- Patients must meet the following laboratory criteria:
- Serum albumin ≥ 3 g/dL
- Aspartate aminotransferase (AST)/SGOT and alanine aminotransferase (ALT)/SGPT ≤ 2.5 x upper limit of normal (ULN) ) or ≤ 5.0 x ULN if the transaminase elevation is due to leukemic involvement

- Serum phosphorus ≥ LLN
- Serum total calcium (corrected for serum albumin) or serum ionized calcium ≥ LLN
- Serum magnesium ≥ LLN, thyroid stimulating hormone (TSH) and free thyroxine (T4) within normal limits (WNL) (patients may be on thyroid hormone replacement)
- Baseline MUGA or ECHO must demonstrate left ventricular ejection fraction (LVEF) ≥ the lower limit of the institutional normal.

- Impaired cardiac function including any one of the following:
- Screening electrocardiogram (ECG) with a QTc > 450 msec confirmed by central laboratory prior to enrollment to the study
- Patients with congenital long QT syndrome
- History of sustained ventricular tachycardia
- Any history of ventricular fibrillation or torsades de pointes
- Bradycardia defined as heart rate < 50 beats per minute. Patients with a pacemaker and heart rate ≥ 50 beats per minute are eligible.

- Impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of oral LBH589
- Other concurrent severe and/or uncontrolled medical conditions
- Patients who have received chemotherapy or any investigational drug < 2 weeks or hydroxyurea < 48 hours prior to starting study drug or who have not recovered from side effects of such therapy.
- Concomitant use of any anti-cancer therapy or radiation therapy
- Male patients whose sexual partners are women of child bearing potential (WOCBP) not using effective birth control
- Patients with known positivity for human immunodeficiency virus (HIV) or hepatitis C; baseline testing for HIV and hepatitis C is not required
- Patients with any significant history of non-compliance to medical regimens or with inability to grant a reliable informed consent
- Patients who will need valproic acid for any medical condition during the study or within 5 days prior to first LBH589 treatment
- Patients who have received targeted agents within 2 weeks or within 5 half-lives of the agent and active metabolites (whichever is longer) and who have not recovered from side effects of those therapies
- Patients who have undergone major surgery ≤ 4 weeks prior to starting study drug or who have not recovered from side effects of such therapy.
