About this study

Official title: Phase I Study of Intraventricular Infusions of Autologous Ex Vivo-Expanded NK Cells in Children With Recurrent/Refractory Malignant Posterior Fossa Tumors of the Central Nervous System. NOAH's (New Opportunity, Advancing Hope) Protocol

This phase I trial studies the side effects and best dose of expanded natural killer cells in treating younger patients with brain tumors that have come back or do not respond to treatment. Infusing a particular type of a patient's own white blood cells called natural killer cells that have been through a procedure to expand (increase) their numbers may work in treating patients with recurrent/refractory brain tumors.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To establish the safety, feasibility, efficacy, and maximum tolerated dose (MTD) of administering autologous natural killer (NK) cells that have been propagated ex vivo with artificial antigen-presenting cells (aAPC) and administered directly into the ventricle in recurrent /refractory malignant posterior fossa tumors.

SECONDARY OBJECTIVES:

  1. To assess the antitumor activity based on imaging and cytology of autologous NK cell locoregional administration directly into the lateral or fourth ventricle.

II. To determine the persistence of adoptively-transferred expanded NK cells (as performed with excess NK cells, via optional correlative studies).

III. Determine the immunophenotype and function of expanded NK cells. IV. Determine the overall response of medulloblastoma to NK-cell therapy. V. Correlate NK cell persistence, phenotype, and function with overall response.

OUTLINE: This is a dose-escalation study.

Patients receive autologous expanded NK cells intravenously (IV) into the ventricle over 3 minutes once weekly on weeks 1-3. Treatment repeats every 4 weeks for up to 3 courses in the absence of disease progression or unacceptable toxicity. Patients experiencing disease progression may continue treatment at the discretion of the treating physician if pseudo-progression or benefit of slowed progression is suspected.

After completion of study treatment, patients are followed up within 30 days.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maximum tolerated dose (MTD) of natural killer (NK) cells

    Defined as the highest dose studied in which 6 patients have been treated at most 1 patient with dose limiting toxicities are observed. Toxicities will be summarized by tabulation in terms of type, grade and attribution for each dose level of each group of patients studied at the end of the trial.

    Measured: 4 weeks

Secondary outcomes (6)
  1. Activation status of NK cells

    Determined by flow-based activation assay determining cluster of differentiation (CD)107a expression of NK cells in response to standardized targets.

    Measured: Up to 30 days after the last infusion in course 3

  2. Persistence of NK cells

    Peripheral blood and cerebrospinal fluid (CSF) will be obtained before therapy, during the NK cell treatment period, and after NK cell treatment.

    Measured: Up to 30 days after the last infusion in course 3

  3. Function of NK cells

    Assessed by cell lysis of standardized targets.

    Measured: Up to 30 days after the last infusion in course 3

  4. Response of medulloblastoma to NK cells

    Antitumor activity will be described for each group of patients based on imaging and cytology. Clinical response will be correlated with NK cell persistence in vivo, cytokine levels, and expression of activation markers.

    Measured: Up to 30 days after the last infusion in course 3

  5. Feasibility of NK cell manufacturing

    If analysis shows < 50% successful product generation after at least six patients have been enrolled, the study will be temporarily stopped to address possible changes in the manufacturing process.

    Measured: Up to 12 weeks

  6. Feasibility of delivering NK cells

    Therapy will be considered feasible if at least 2/3 of subjects treated receive at least 21 of the planned 27 NK cell infusions.

    Measured: Up to 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Laboratory Biomarker Analysis and Natural Killer Cell Therapy in people with Recurrent Childhood Medulloblastoma and Recurrent Ependymoma, run by M.D. Anderson Cancer Center 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 13 inclusion and 6 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 2 Sep 2020. 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 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.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Maximum tolerated dose (MTD) of natural killer (NK) cells (time frame: 4 weeks). 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 2 Sep 2020.
