Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 2 to 21 years
  • All sexes
  • No healthy volunteers
  • Child, Adult

Who may be able to join

  • Patients with newly diagnosed DIPG by magnetic resonance imaging (MRI); defined as patients with a pontine location and diffuse involvement of at least 2/3 of the pons are eligible without histologic diagnosis. For lesions with typical imaging features, biopsy is neither encouraged nor required for eligibility. Tumors that are biopsied will be eligible if proven to be supportive of the diagnosis of a DIPG. Consensus of diagnosis by the study team must be met.
  • Patients who have completed focal radiotherapy within 14 weeks from time of enrollment are eligible.
  • Treatment must begin at a minimum of 4 weeks after, but no later than 14 weeks after, the date of completion of focal radiotherapy.
  • Prior chemotherapy: Patients should be at least 30 days from last chemotherapy dose prior to start of CED infusion, with exception of antibody half-lives. For antibody therapies, at least 3 half-lives of the antibody after last dose of monoclonal antibody should have passed prior to CED infusion. Patients less than 30 days from last chemotherapy dose should be discussed with the study chair(s).
  • Prior radiation: Patients must have received prior treatment with focal radiotherapy as part of initial treatment for DIPG and had their last dose at least 4 weeks prior to and no later than 14 weeks from the first CED treatment. Standard focal radiation therapy will include 54 to 60 Gy by external beam radiotherapy to the brainstem.
  • Age ≥ 2 years of age to 21 years. Patients younger than 3 years of age may be enrolled on study at the discretion of the Study Chair(s) if supporting evidence that brainstem lesion represents a brainstem glioma.

  • Karnofsky Performance Score ≥ 50 for patients > 16 years of age and Lansky Performance Score ≥ 50 for patients ≤ 16 years of age. Patients who are unable to walk because of paralysis, but who are able to mobilize using a wheelchair, will be considered ambulatory for the purpose of assessing the performance score.
  • Life expectancy of greater than 12 weeks measured from the date of completion of radiotherapy.
  • Corticosteroids: Patients who are receiving dexamethasone must be on a stable or decreasing dose for at least 1 week prior to registration.
  • Peripheral absolute neutrophil count (ANC) ≥ 1000/mm^3.
  • Hemoglobin ≥ 8g/dl.
  • Platelet count ≥ 100,000/mm^3 (transfusion independent, defined as not receiving platelet transfusions for at least 7 days prior to enrollment).
  • Normal coagulation defined as normal International Normalized Ratio (INR) or per institutional guidelines.
  • Creatinine clearance or radioisotope glomerular filtration rate (GFR) ≥ 70 milliliters (mL)/minute (min)/1.73 m^2.

  • Serum glutamate pyruvate transaminase (SGPT) [alanine aminotransferase (ALT)] ≤ 110 U/L.
  • Serum albumin ≥ 2 g/dL.
  • Patients with seizure disorder may be enrolled if on non-enzyme inducing anticonvulsants and well controlled.
  • The effects of MTX110 on the developing human fetus are unknown. For this reason women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation and 4 months after completion of MTX110 injection administration. 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.

  • Untreated symptomatic hydrocephalus determined by treating physician.
  • Patients with evidence of intra-tumoral hemorrhage > 5 mm maximal diameter. These subjects should be discussed with the study chair.
  • Subjects with prolonged corrected QT (QTc) (> 450 msec) will be excluded from the study.

About this study

Official title: An Open Label Single Arm Phase I/II Study of MTX110 Delivered by Convection-enhanced Delivery (CED) in Patients With Diffuse Intrinsic Pontine Glioma (DIPG) Previously Treated With External Beam Radiation Therapy

This phase I/II trial studies the side effects of panobinostat nanoparticle formulation MTX110 (MTX110) in treating participants with newly-diagnosed diffuse intrinsic pontine glioma. Panobinostat nanoparticle formulation MTX110 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the safety and tolerability of repeated administration of MTX110 co-infused with gadoteridol given by intratumoral convection enhanced delivery in children with newly diagnosed diffuse intrinsic pontine glioma (DIPG).

SECONDARY OBJECTIVES:

  1. To determine the clinical efficacy of repeated administration of MTX110 given by intratumoral convection-enhanced delivery (CED) in children with newly diagnosed DIPG in the confines of a phase I and early efficacy study.

OUTLINE: This is a phase I, dose-escalation study followed by a phase II study.

Participants receive panobinostat nanoparticle formulation MTX110 intratumorally (IT) by CED infusion on day 1 or days 1 and 2 as determined by dose level. Courses repeat every 4-8 weeks for up to 24 months in the absence of disease progression or unacceptable toxicity.

After completion of study treatment participants are followed up at 30 days and then every 2 months.

    Adverse events and clinically significant laboratory abnormalities which meet Grade 3, 4, or 5 criteria according to Common Terminology Criteria for Adverse Events (CTCAE) classified by investigators and treating physicians as related to study treatment (probable, possible, and definite) will be summarized by maximum intensity/grade. Adverse events will be graded according to CTCAE version 4.0.

    Measured: Up to 12 Months

Secondary outcomes (1)
  1. Overall Survival Rate (OS) at 12 Months

    Overall survival is defined as the percentage of participants alive from time of diagnosis up to 12 months.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Panobinostat Nanoparticle Formulation MTX110 and Convection-Enhanced Delivery (CED) in people with Diffuse Intrinsic Pontine Glioma, run by Sabine Mueller, MD, PhD at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 27 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 25 Feb 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of Participants With Grade 3 or Higher, Treatment-related, Adverse Events (time frame: Up to 12 Months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Feb 2022.
