Brief Title  ICMJE Multi-antigen T Cell Infusion Against Neuro-oncologic Disease
Official Title  ICMJE Phase I REsearch on Multi-antigen T Cell Infusion Against Neuro-oncologic Disease
Brief Summary

This Phase I dose-escalation trial is designed to determine the safety and feasibility of rapidly generated tumor multi-antigen associated specific cytotoxic T lymphocytes (TAA-T) in patients with newly diagnosed diffuse intrinsic pontine gliomas DIPGs (Group A) or recurrent, progressive, or refractory non-brainstem CNS malignancies (Group B).

Pediatric and adult patients who have high-risk CNS tumors known to typically have positivity for one or more Tumor Antigen Associated (TAA) (WT1, PRAME and/or Survivin) will be eligible. TAA-T will all be generated from patient peripheral blood mononuclear cells (PBMC).

Group A patients (DIPG): The first TAA-T dose will be infused any time >14 days after completion of radiotherapy.

Group B patients (other recurrent/progressive/refractory CNS tumors): The first TAA-T dose will be infused any time >14 days after completing most recent course of conventional (non-investigational) therapy for their disease AND after appropriate washout periods as detailed in eligibility criteria.

Detailed Description

This protocol is designed as a phase I dose-escalation study. Three different TAA-T dose levels will be evaluated in each treatment group (A and B) (see below) with 2 to 4 patients enrolled at each dose level.

Dose Level 1: 2 x 107 cells/m2 Dose Level 2: 4 x 107 cells/m2 Dose Level 3: 8 x 107 cells/m2

Two patients will be initially enrolled to the lowest dose level cohort (separately on each arm) and followed for 42 days after initial TAA-T for DLT evaluations. The decision on whether it is safe to escalate to next dose level or not will be made after at least two patients in each dose level have finished their 42-days toxicity follow up after initial TAA-T. If the first two patients have not finished their 42 days follow-up, up to 2 additional incoming patients can be enrolled at the current dose level.

Ideally, patients should not receive other systemic antineoplastic agents for at least 42 days after infusion of TAA-T (for purposes of evaluation), although such treatment may be added if deemed critical for patient care by the attending physician.

Each patient will receive at least one TAA-T infusion and may receive a maximum of 8 subsequent infusions. The first and second infusions will be administered at least 42 days apart then additional infusions will be spaced at least 28 days apart from each other. The expected volume of each infusion is 1 to 10 ml.

If patients with disease have a response of stable disease or better by RANO criteria (see section 3.2.2.4) at the day 28 evaluation after the second infusion OR if they have clinical stability and a clinical assessment of possible pseudoprogression on MRI, they are eligible to receive up to 6 additional infusions of TAA-T at 28 day intervals if available. Each subsequent infusion will be the same as the enrollment dose level (i.e. no subsequent dose escalation). The first and second infusions will be administered at least 42 days apart then additional infusions will be spaced at least 28 days apart from each other. Following the first infusion, if a patient's TAA-T supply is insufficient for subsequent infusions at the enrollment dose level, further treatments may be administered at a lower dose level at the treating physician's discretion.

If patients who are clinically stable are deemed to have likely pseudoprogression at the disease evaluation after the second infusion or on subsequent imaging, then these patients may still be eligible for infusion if serial imaging and clinical assessments demonstrate stability most consistent with pseudoprogression. In these patients, disease assessment after the imaging that first raises the concern for pseudoprogression (potential progressive disease versus pseudoprogression) must be at least stable when compared with the first scan demonstrating pseudoprogression.

Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 1
Study Design  ICMJE Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE Brain Tumor
Intervention  ICMJE Biological: TAA-T
Patients with newly diagnosed diffuse intrinsic pontine gliomas DIPGs (Group A) or recurrent, progressive, or refractory non-brainstem CNS malignancies (Group B). The goal of this cell infusion will be to initiate an immune response against brain tumors that includes multiple antigens and may prevent tumor evasion (through decreased expression of a single antigen)
Study Arms  ICMJE Experimental: TAA-T

Three different dosing schedules will be evaluated.

Dose Level One: 2 x 107 cells/m2 Dose Level Two: 4 x 107 cells/m2 Dose Level Three: 8 x 107 cells/m2

Group A patients (DIPG): The first TAA-T dose will be infused any time more than or equal to 14 days after completion of radiotherapy.

Group B patients (other recurrent/progressive/refractory CNS tumors): TAA-T will be infused any time more than or equal to 14 days after completing most recent course of conventional (non-investigational) therapy for their disease AND after appropriate washout periods as detailed in eligibility criteria.

Ideally, patients should not receive other systemic antineoplastic agents for at least 42 days after the infusion of TAA-T, although such treatment may be added if deemed critical for patient care by the attending physician.

Intervention: Biological: TAA-T

Eligibility Criteria  ICMJE

Inclusion Criteria:

Recipient Procurement Inclusion Criteria

  • Diagnosis of high-risk CNS tumors: DIPG, high-grade glioma, medulloblastoma, ependymoma, embryonal tumors, choroid plexus carcinoma, other aggressive CNS malignancies.

    o Group A (newly diagnosed DIPG): Radiographic diagnosis with DIPG defined as tumors with a pontine epicenter and diffuse intrinsic involvement of the pons. For Group A, procurement within the first 12 weeks after completion of radiotherapy is required.

    • Group B: Recurrent, progressive, or refractory disease after standard treatment. Refractory disease includes high-risk tumors with residual disease after completion of standard treatment or tumors with known poor cure rates with standard treatment.
  • 6 months to 80 years of age at enrollment
  • Karnofsky/Lansky score of ≥ 60%

These include the following: Tumor with any evidence of uncal herniation or significant midline shift Tumor with a significant brainstem component Patients who are deemed to have overly bulky tumor by the PI of the study

    • Pregnancy assessment on all patients >7 years will be performed. If patient has child bearing potential (per PI/Sub-I discretion), then pregnancy testing will be performed.

Recipient Inclusion Criteria for Initial TAA-T Administration and for Subsequent Infusions

  • Steroids < 0.5 mg/kg/day dexamethasone or equivalent
  • Karnofsky/Lansky score of greater than or equal to 60%
  • Organ function:

    o ANC greater than or equal to750/µL

    o Platelets greater than or equal to 75K

    • Bilirubin less than or equal to 1.5x ULN
    • AST/ALT less than or equal to 5x ULN

    o Investigational agent: 28 days prior to TAA-T infusion. For investigational agents that have known adverse events occurring beyond 28 days after administration, this period must be extended beyond the time when new adverse events are known to commonly occur.

    • Biologic agents: 7 days prior to TAA-T infusion. For agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time when new adverse events are known to commonly occur.
    • Bevacizumab: bevacizumab may be used if clinically indicated in order to control potential pseudoprogression* or inflammation thought to be due to the cellular product. There will not be a standard required washout period for bevacizumab if used for this indication.
    • Surgery: patients must have recovered from all acute effects of prior surgical intervention
  • Neurologic status: Patients with neurologic deficits must have deficits that are stable for a minimum of 7 days prior to TAA-T infusion

    • Pseudoprogression is a retrospective assessment that some (or all) noted tumor enlargement by radiographic criteria may reflect immune cell infiltration rather than true tumor progression. This diagnosis is commonly accepted to be retrospectively true if, in the context of clinical stability, radiographic progression plateaus when it would have been expected to progress.
