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

Condition or disease Intervention/treatment Phase
Diffuse Intrinsic Pontine Glioma Pediatric Brainstem Glioma Pediatric Brainstem Gliosarcoma, Recurrent Pediatric Cancer Pediatric Brain Tumor Diffuse Glioma Drug: Marizomib Drug: Panobinostat Phase 1

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.

    • 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
    • Platelets ≥ 100,000/ mm3 (unsupported, defined as no platelet transfusion within 7 days, and recovery from post-transfusion nadir)

    • Potassium within institutional normal range
    • Serum total calcium (correct for serum albumin) or ionized calcium within institutional normal range
    • Serum creatinine based on age/gender as noted in Table 2. Patients who do not meet the criteria in the table but who have a 24-hour Creatinine Clearance or GFR (radioisotope or iothalamate) ≥ 70 mL/min/1.73 m2 are eligible.

      • Table 2: Serum Creatinine for age/sex Serum Creatinine for age/sex Age Maximum Serum Creatinine (mg/dL) Male Female < 3 years < 0.8 < 0.8 3 to < 6 years 0.8 0.8 6 to < 10 years 1 1 10 to < 13 years 1.2 1.2 13 to < 16 years 1.5 1.4

        • 16 years 1.7 1.4 The threshold creatinine values in this Table were derived from the Schwartz formula for estimating GFR(63) utilizing child length and stature data published by the CDC.

    • Patient must have a QTcF interval < 450 milliseconds (ms).
  • Patients must be off all colony-forming growth factor(s) (i.e. filgrastim, sargramostim or erythropoietin) for at least 7 days prior to enrollment; 14 days must have elapsed if patients received PEG formulations.
  • Patients must agree to avoid grapefruit or grapefruit juice and Seville (sour) oranges during the entire study as these are known to interfere with panobinostat pharmacokinetics.
  • Pregnant and breastfeeding women are excluded from this study because marizomib and panobinostat's potential for teratogenic or abortifacient effects is unknown. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with marizomib or panobinostat, breastfeeding should be discontinued if the mother is treated with marizomib or panobinostat.
  • The effects of marizomib and panobinostat on the developing human fetus are unknown. For this reason, women of child-bearing potential and men (including those who have had a vasectomy) must agree to use contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation and up to 3 months for a female and 6 months for a male after the last dose of the drug (either marizomib or panobinostat, whichever is administered last). If you are able to become pregnant, you will have repeat pregnancy tests during the test. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.
  • Ability to understand and the willingness to sign a written informed consent document.

Exclusion Criteria:

  • Patients who have received > 60 Gy total radiation to the pons (e.g. patients who have received re-irradiation) due to potential increased risk of intratumoral hemorrhage
  • Patients who have had prior bone marrow transplant or received marrow ablative therapy
  • Patients with implanted CED catheters (e.g. Renshaw) due to inability to fully evaluate disease status
  • Patients with a history of spinal radiation or those with an indication for acute spine radiation (e.g. significant cord compression) (Patients with leptomeningeal disease may be eligible but should be reviewed with study PI prior to enrollment).

  • Patients with current or prior history of posterior reversible encephalopathy syndrome (PRES)
  • Patients with significant (i.e. requiring active/ongoing treatment) GI dysfunction or GI disease, e.g. inflammatory bowel disease.
  • Patients with chronic diarrhea or current diarrhea (≥ 4 stools/day).
  • Patients with any clinically significant unrelated systemic illness (e.g. serious 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.
  • Any ventricular arrhythmias with the exception of benign premature ventricular contractions
  • Patients known to be refractory to red blood cell or platelet transfusions. Patients who are receiving any other anticancer or investigational drug therapy
  • Patients who are required to receive any medication listed in Appendix B or is otherwise known to significantly prolong the QTc interval. (Note: Loperamide use is acceptable at doses no higher than listed in this protocol).
  • Patients who are taking cannabinoids, cannabinoid oils, any psychoactive supplement, narcotics, or any agent that can potentially cause hallucinations, disorientation, confusion or dizziness
