A Study Of Panobinostat In Children With Refractory Hematologic Malignancies
Phase: Phase 1
Diagnosis: Pediatric Leukemia
NCT ID: NCT01321346
(View complete trial on ClinicalTrials.gov)
DFCI Protocol ID: 12-516
This study is for patients with relapsed or refractory Acute Lymphoblastic Leukemia (ALL), Acute Myelogenous Leukemia (AML), Hodgkin's Disease (HD) or Non-Hodgkin's Lymphoma (NHL). Panobinostat is a new drug that is considered investigational because it has not been approved in the United States by the Food and Drug Administration (FDA), or in any other country. Panobinostat is a histone deacetylase inhibitor (HDACi) and interferes with gene expression found in cells causing them to stop growing or die. Panobinostat has been used in several hundred adults who had leukemia, HD, NHL and other solid tumors. Panobinostat has not been given to children. This is a phase I study. In a phase I study, drugs are tested to the highest dose that can be safely given. Drugs are given at gradually increasing dosages until there are unacceptable side effects. The goal of the Phase I study is to find out the dose of panobinostat that can be safely given to children with relapsed ALL, AML, HD and NHL.

- Patients must be ≥ 8 and ≤ 21 years of age at the time of enrollment.
- Patients must have one of the following:
1. Patient must have relapsed/refractory acute myelogenous leukemia (AML) with ≥ 5%
blast in the bone marrow or biopsy confirmed chloroma. Patient may have CNS 1, 2
or 3 disease. Isolated CNS relapse is not eligible.
2. Patient must have relapsed/refractory acute lymphoblastic leukemia (ALL) with ≥
5 blasts in the bone marrow or biopsy confirmed extramedullary disease. Patient
may have CNS 1, 2 or 3 disease. Isolated CNS relapse is not eligible.
3. Patient must have relapsed or refractory non-Hodgkin's lymphoma (NHL) or
Hodgkin's disease. Patients must have CNS 1 disease. Patient must have
histologic verification of disease at original diagnosis. Patient must have
measurable disease documented by clinical or radiographic criteria or bone
marrow disease present at study entry.
- Karnofsky > 50% for patients > 16 years of age and Lansky > 50% for patients less
than or equal to 16 years of age. (See Appendix I for Performance Scales).
- Patient must have a life expectancy of 8 weeks.
- PRIOR THERAPY Patients must have fully recovered from the acute toxic effects of all
prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study.
1. Patients with AML must have had at least 2 prior therapeutic attempts including
2. Patients with ALL must have had at least 3 prior therapeutic attempts including
3. Radiotherapy: At least 28 days must have elapsed since and radiation therapy.
4. Hematopoietic Stem Cell Transplant:
Patients who have had previous allogeneic HSCT must have grade I or less of
Graft-versus-Host Disease (GVHD) and have not received immunosuppressive
medication for at least 90 days.
5. Hematopoietic grow factors: It must have been at least 7 days since the
completion of therapy with GCSF or other growth factors at the time of
enrollment. It must have been at least 14 days since the completion of therapy
with pegfilgrastim (Neulasta®).
6. Biologic/Immunologic (anti-neoplastic) therapy: It must be at least 28 days
since the completion of therapy with a biologic/immunologic agent such as a
monoclonal antibody prior to study enrollment and at least 28 days since
non-study chemotherapy has been administered, excluding CNS directed therapy as
described in Section 4.1.
7. Prior HSCT for Hodgkin's Lymphoma: Patients with Hodgkin's lymphoma must have
had prior attempt at autologous HSCT.
- Renal and Hepatic Function
1. Patient's serum creatinine must be ≤ 1.5 x institutional upper limit of normal
(ULN) according to age. If the serum creatinine is greater than 1.5 times
normal, the patient must have a calculated creatinine clearance or radioisotope
GRF ≥ 70mL/min/1.73m2.
- Pediatric Population (age <18): Calculated creatinine clearance ≥ 90
ml/min/1.73m2 as calculated by the Schwartz formula for estimated
glomerular filtration rate (GFR)
- Adult Population (age >18): Serum creatinine <1.0 mg/dL; if serum
creatinine >1.0 mg/dL, then the estimated glomerular filtration rate (GFR)
must be >60 mL/min/1.73 m2
2. Patient's ALT must be < 5 x institutional upper limit of norm ULN.
3. Patient's total bilirubin must be ≤ 1.5 x ULN.
- Cardiac Function
a. Patient must have a shortening fraction ≥ 29% or an ejection fraction ≥ 40% by

1. Female patients of childbearing potential must have a negative urine or serum
pregnancy test confirmed prior to enrollment.
2. Female patients with infants must agree not to breastfeed their infants while on

effective method of contraception approved by the investigator during the study.
