Detailed Description

This research study involves chemotherapy as a possible treatment for pediatric patients with Diffuse intrinsic pontine glioma (DIPG) - The research study procedures include screening for eligibility and study treatment including evaluations and follow up visits. - The names of the study drugs involved in this study are: - Marizomib - Panobinostat This study consists of 2 parts: - Part A : The investigators are looking at the highest dose (up to a targeted maximum dose) of the study drug Marizomib that can be administered safely without severe or unmanageable side effects in participants that have DIPG, not everyone who participates in this research study will receive the same dose of the study intervention. The dose given will depend on the number of participants who have been enrolled prior and how well the dose was tolerated. - Part B: Participants who tolerate Marizomib alone will be treated with Marizomib and panobinostat, but at lower dose of marizomib than the dose of marizomib when given alone. Participants are expected to be on study treatment for up to 2 years followed for up to 5 years. It is expected that up to 45 people will take part in this research study. This research study is a Phase I clinical trial, which tests the safety of an investigational drug and also tries to define the appropriate dose of the investigational drug to use for further studies. "Investigational" means that the drug is being studied. - Marizomib has not been approved by the U.S. Food and Drug Administration (FDA) as a treatment for any disease. -- This is the first time Marizomib will be given to children. - Panobinostat has not approved by the U.S. Food and Drug Administration (FDA) for the treatment of diffuse intrinsic pontine glioma but it has been approved for other uses.

Criteria

Inclusion Criteria:

- Patients must have DIPG, as defined below, to be eligible for this protocol. Given the
poor prognosis of all patients with DIPG, patients may enroll at any point in their
disease course provided they have received standard radiation therapy (also defined
below) and meet all other eligibility requirements.

- DIPG is defined, for this study, as a diffusely infiltrative lesion with the epicenter
in the pons, involving at least 2/3 of the pons as assessed by T2 or FLAIR imaging,
and with no major or primary exophytic component, OR a pontine-based lesion that is
biopsy proven non-pilocytic, WHO II-IV glioma. H3K27M status will be assessed in
patients when tissue is available, but patients are eligible regardless of H3K27M
status. (Biopsy will NOT be performed as part of this study).

- Standard radiation therapy is defined, for this study, as 54-60 Gy standard focal
(photon or proton) radiation therapy, administered over 6 weeks (+/- 10 days).
Patients who receive standard radiation therapy with concurrent chemotherapy may be
eligible as long as other criteria are met.

- Patients must be < 22 years of age at the time of enrollment. - Patient must be able to swallow capsules whole. - Karnofsky Performance Scale (KPS, for ≥ 16 years of age) or Lansky Performance Scale (LPS, for < 16 years of age) assessed within 7 days prior to treatment initiation must be ≥ 50%.

This includes any investigational therapy, including (but not limited to) those given in other countries or in private clinics.

infections, mental illness, or significant cardiac, pulmonary, hepatic or other organ
dysfunction), that, in the opinion of the investigator, would compromise the ability
of the patient to tolerate protocol therapy or put them at additional risk for
toxicity or would interfere with the study procedures, ability to assign attribution,
or results.

narcotics, or any agent that can potentially cause hallucinations, disorientation,
confusion or dizziness

are eligible if they discontinue enzyme-inducing antiepileptic drugs and/or valproic
acid prior to enrollment and have a washout period of least 5 half-lives.

for required follow-up visits or obtain follow-up studies required to assess toxicity
to therapy or to adhere to drug administration plan, other study procedures, and study
restrictions
