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 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • One of the following diagnoses of GBM:
  • Newly diagnosed glioblastoma multiforme that is histologically confirmed by pathology review of surgically resected tissue; OR b. An integrated molecular/pathologic diagnosis of diffuse astrocytic glioma, IDH-wildtype, with molecular features of glioblastoma, WHO grade IV. This diagnosis requires patients have one of the following: i. High-level amplification of EGFR; OR ii. Combined whole chromosome 7 gain and whole chromosome 10 loss (+7/-10); OR iii. TERT promoter mutation.
  • Undergone tumor resection.
  • No prior systemic therapies, radiation, tumor-treating fields, or intratumoral therapeutic agents including Gliadel wafers are allowed. Tumor resection must be the only tumor-directed treatment that the patient has received for glioboblastoma.
  • Tumor tissue is positive for EGFRvIII expression, as performed by either the University of Pennsylvania's in-house fusion transcript panel (RNA-based assay using Illumina HiSeq platform) or NeoGenomics Laboratories (quantitative RT-PCR assay).
  • Tumor tissue is negative for MGMT promoter methylation (i.e. the tumor is MGMT-unmethylated), as performed by either the University of Pennsylvania's in-house pyrosequencing protocol or NeoGenomics Laboratories.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CART-EGFRvIII T cellsBiological

    autologous T cells that have been engineered to express an extracellular Humanized single chain antibody (scFv) with specificity for EGFRvIII linked to an intracellular signaling molecule comprised of a tandem signaling domain of the 4-1BB and TCRζ signaling modules.

  • PembrolizumabBiological

    Also called Keytruda

    humanized monoclonal immunoglobulin (Ig) G4 antibody directed against human cell surface receptor PD-1 (programmed death-1 or programmed cell death-1) with potential immune checkpoint inhibitory and antineoplastic activities.

What is being measured

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

  1. Number of subjects with treatment-related adverse events, using NCI CTCAE v5.0.

    Measured: 15 Years

Secondary outcomes (3)
  1. Overall survival Rate

    Number of days from the date of the first CART-EGFRvIII infusion to the date of death of any cause. The survival function of OS will be calculated by the Kaplan-Meier method.

    Measured: 15 Years

  2. Progression-free survival (PFS)

    The number of days from the date of the first CART-EGFRvIII infusion to the first documented disease progression (based on standard MRI evaluation using the modified RANO criteria) or date of death, whichever occurs first. PFS will be calculated by the Kaplan-Meier method.

    Measured: 15 Years

  3. Objective response rate (ORR)

    The proportion of patients with complete response (CR) or partial response (PR) out of the total number of efficacy evaluable subjects. Exact 90%confidence interval for ORR will be computed.

    Measured: 15 Years

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CART-EGFRvIII T cells and Pembrolizumab in people with Glioblastoma, run by University of Pennsylvania 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 15 inclusion and 17 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 22 Jun 2023. 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?

Number of subjects with treatment-related adverse events, using NCI CTCAE v5.0. (time frame: 15 Years). 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 22 Jun 2023.
