Brief Summary

Please note that enrollment on this study terminated early due to the end of grant funding. Newly diagnosed WHO grade IV malignant glioma subjects who are eligible were enrolled following surgery to remove their brain tumor. They then underwent a leukapheresis to harvest cells for the generation of the study drug, Epidermal Growth Factor variant III Chimeric Antigen Receptor (EGFRvIII CAR) T cells prior to beginning standard of care (SOC) radiation therapy (RT) with temozolomide (TMZ). Once SOC RT with TMZ was completed, subjects returned for the post-RT brain imaging assessment, and, if stable, started post-RT TMZ cycles. Patients received up to 3 cycles of dose-intensified TMZ prior to receiving the EGFRvIII CAR T cells, which was infused in dose escalation cohorts. Following a one-month delay between cycles, the subject resumed post-RT cycles of TMZ and were monitored with blood work and brain imaging as per SOC. An expanded cohort of 12 subjects was originally planned for once the maximally tolerated dose (MTD) was reached in the dose escalation cohorts, in order to obtain a more precise estimate of the probability of unacceptable toxicity and to track the EGFRvIII CAR T cells using 111 Indium (111In) labeling. Computed Tomography (CT) was planned on days 1, 2, and 3 post-infusion to determine intracerebral (IC) localization.

Outcome Measures

Primary Outcomes (1)

  • Maximally Tolerated Dose

    Within this "3+3" phase I study, the primary objective is to determine the MTD of a single IV infusion of EGFRvIII CAR T cells in patients with newly-diagnosed WHO grade IV malignant glioma. Four dose levels were to be considered based on transduced cells/kg: #1: 4.5 x 10\^6/kg, #2: 1.5 x 10\^7/kg, #3: 4.5 x 10\^7/kg, and #4: 1.5 x 10\^8/kg. The MTD is the highest dose level at which ≤1 of 3-6 patients experience dose-limiting toxicity during the 4 weeks after CAR infusion.

    12-18 months

Secondary Outcomes (1)

  • Number of Patients Who Experienced a Dose-limiting Toxicity (DLT)

    12-18 months

Study Arms (1)

EGFRvIII CAR T cells

EXPERIMENTAL

Dose escalation cohorts for 4 dose levels will be considered: #1: 4.5 x 10\^6/kg, #2: 1.5 x 10\^7/kg, #3: 4.5 x 10\^7/kg, and #4: 1.5 x 10\^8/kg. Starting at dose level 1, cohorts of 3-6 subjects will be accrued at each dose level.

Biological: EGFRvIII CAR T cells

Interventions

The name of the drug is CAR gene-modified T cells or abbreviated as EGFRvIII CARs. The class of action is a biological and the mechanism of action is cytotoxicity. The drug substance is autologous T cells transduced with a retroviral vector encoding for a chimeric antigen receptor (CAR) directed against the tumor specific antigen, EGFRvIII. EGFRvIII CARs are genetically engineered T cells that have been taken from patients with GBM ex vivo to express a CAR recognizing the GBM tumor-specific antigen EGFRvIII, which is expressed on a subset of GBMs but not in normal human tissues with the aim of mediating regression of their tumors. Patients' CARs will be radiolabeled with 111In for correlative studies in the expanded cohort.

Also known as: EGFRvIII CARs, CAR-specific T cells, CAR T cells, CARs, 111Indium Labeled EGFRvIII CARs, 111In-Labeled EGFRvIII CARs, CAR gene-modified T cells, 111In-labeled CARs
