Eligibility Criteria

undefined - 21 Years (Child, Adult)All SexesDoes not accept healthy volunteers

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.

    • Patient must have recovered (< Grade 1) from any acute toxicity potentially related to the agent and received their last dose of the investigational or biologic agent ≥ 7 days prior to study enrollment.

      • For agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur and discussed with the principal investigator.
    • Monoclonal antibody treatment and agents with known prolonged half-lives: At least three half-lives must have elapsed prior to enrollment due to the potential risk of pseudoprogression.
    • Checkpoint inhibitors, vaccine, or CAR T cell therapy: At least 3 months must have elapsed from last treatment prior to enrollment due to the risk of pseudo-progression.
    • Convection Enhanced Delivery (CED)

      • Patients must be at least 4 weeks from last CED procedure, have no permanent indwelling CED device, and no evidence of acute or ongoing intra-tumoral hemorrhage as demonstrated by gradient echo MRI. Additionally, patients must have recovered (< Grade 1) from any acute toxicity potentially related to the infused agent or procedure.
    • Intra-arterial therapy: Patient must be at least 4 weeks from most recent procedure, regardless of chemotherapeutic agent(s) infused and no evidence of acute or ongoing intratumoral hemorrhage as demonstrated by gradient echo MRI. Additionally, patients must have recovered (< Grade 1) from any acute toxicity potentially related to the infused agent or procedure.
    • Information regarding any prior investigational therapy or procedure, including (but not limited to) agent(s), dose, method of administration, dates of administration, concomitant therapies, all toxicities reported to date and anticipated toxicities, must be available for review by this study PI prior to patient enrollment. This includes any investigational therapy, including (but not limited to) those given in other countries or in private clinics.

If information on an investigational therapy is unavailable or the PI cannot assess ongoing potential risk of a prior therapy, the patient is not eligible.

  • Patients must have adequate organ and marrow function as defined below:

    • Absolute neutrophil count (ANC) ≥ 1,000/mm3

Brief Summary
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
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.
