Summary
This phase I trial studies the side effects and best dose of panobinostat in treating younger patients with diffuse intrinsic pontine glioma (DIPG). Panobinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Stratum 1 treats patients with DIPG that has returned or gotten worse (progressed). Stratum 2 treats patients with DIPG that has not yet gotten worse. Currently, only Stratum 2 is enrolling patients.Phase:

Criteria
STRATUM 1 - INCLUSION CRITERIA- DIAGNOSIS - Patients with progressive DIPG, as defined by progressive neurologic
abnormalities or worsening neurologic status not explained by causes unrelated to
tumor progression (e.g., anticonvulsant or corticosteroid toxicity wean, electrolyte
disturbances, sepsis, hyperglycemia, etc.), OR an increase in the bi-dimensional
measurement, taking as a reference the smallest disease measurement recorded since
diagnosis, OR the appearance of a new tumor lesion since diagnosis.
- Please note: patients with a radiographically typical DIPG, defined as a tumor
with a pontine epicenter and diffuse involvement of more than 2/3 of the pons,
are eligible without histologic confirmation.
- Patients with pontine lesions that do not meet these radiographic criteria will
be eligible if there is histologic confirmation of malignant glioma WHO II-IV.
- AGE - Patients must be ≥ 2 but < 22 years of age at the time of enrollment.

administration, this period must be extended beyond the time during which adverse
events are known to occur, and discussed with the principal investigator.)

least three half-lives must have elapsed prior to enrollment. (Note: A list of
