All patients will initially receive marizomib (MRZ) alone (Course A1) The dose escalation and de-escalation for single agent and combination will be guided using the Bayesian optimal interval (BOIN) design

-Intravenously initially given every other week over a 28 day course but may go to weekly x 3 and weekly x 4 as the dose levels increase. Up to 26 courses.

If tolerated,combination of Marizomib: and panobinostat on subsequent cycles. The dose escalation and de-escalation for single agent and combination will be guided using the Bayesian optimal interval (BOIN) design.

* Intravenously initially given every other week over a 28 day course but may go to weekly x 3 and weekly x 4 as the dose levels increase. Up to 26 courses.
* Panobinostat: Oral dosage is given 3 times weekly, every other week over a 28 day course

- Intravenously initially given every other week over a 28 day course but will go to weekly x 3 and weekly x 4 as the dose levels increase Up to 26 courses.

This research study is evaluating the safety, tolerability and preliminary efficacy of the drugs marizomib and panobinostat in pediatric patients with diffuse intrinsic pontine glioma (DIPG).

The names of the study drugs involved in this study are:

* Marizomib
* Panobinostat

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.

Phase 1 Trial of Marizomib Alone and in Combination With Panobinostat for Children With Diffuse Intrinsic Pontine Glioma

The Dana-Farber / Harvard Cancer Center encourages and supports the responsible and ethical sharing of data from clinical trials. De-identified participant data from the final research dataset used in the published manuscript may only be shared under the terms of a Data Use Agreement.

To determine the toxicity profile and any dose-limiting toxicity (DLT) of marizomib as a single agent at doses up to 0.8 mg/m2 , in children with DIPG

To determine the toxicity profile and any DLT of marizomib at doses up to 0.8 mg/m2 when administered in combination with panobinostat to children with DIPG

To estimate the maximum-tolerated dose (MTD) or recommended Phase 2 dose (RP2D) of marizomib when administered as a single agent in children with DIPG

To estimate the MTD or RP2D of marizomib when administered in combination with panobinostat in children with DIPG

Estimated using compartmental methods. Plasma drug concentrations and pharmacokinetic parameters will be presented in tabular and graphical form
