About this trial

This is a phase 1 study for patients with newly diagnosed MGMT unmethylated IDH wild-type glioblastoma utilizing autologous activated T-cells armed with bispecific antibody (EGFR-BATs) that recognize the tumor. The investigators hypothesized that the combination of infusions of EGFR BATs and low-intensity focused ultrasound would induce blood-brain barrier opening and increase the permeability of the adoptive immunotherapy. The investigators will radiolabel the EGFR BATs with 89Zr-oxine for subsequent PET imaging to determine the trafficking and uptake of this approach. There is a concern that several infusions of EGFR BATs before BBB opening could change the immune tumor microenvironment that would not allow a permissive BBB after LIFU. Therefore, Arm A will have two LIFU with BBB opening after the 4th and the 8th infusion, and Arm B will have three LIFU with BBB opening after the 1st, 4th, and 8th infusions. This study will determine the safety and feasibility of the combination of low-intensity focused ultrasound (LIFU) with microbubbles BBB opening and EGFR BATs and the access of the adoptive cell immunotherapy to the tumor microenvironment to inform future studies.

Eligibility criteria

Qualifiers

Newly diagnosed supratentorial glioblastoma or gliosarcoma IDH wildtype and MGMT unmethylated that express EGFR (score ≥ 1 by IHC)) and confirmed by UVA pathology review.

Age ≥ 18 and ≤ 70 years at the time of signing informed consent.

Karnofsky Performance Status (KPS) ≥ 70.

Be willing and able to provide written informed consent for the trial.

Disqualifiers

Patients with a diagnosis of another malignancy within 2 years of being on-study. Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin that has undergone potentially curative therapy, or any type of in situ cancer. Patients must not be on any treatment for another malignancy.

Patients undergoing only biopsy (partial resection or greater is required).

Patients with cerebellar or brainstem tumors.

Patients with evidence of leptomeningeal dissemination or subependymal spread on initial MRI.
