A Phase 1 interventional study of Ex-Vivo expanded autologous IL-8 receptor (CXCR2) modified CD70 CAR (8R-70CAR) T cells in Glioblastoma Multiforme and Glioblastoma, sponsored by University of Florida. Active, not recruiting at 1 site in United States. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2026-09-23.

This is a phase I study to assess the safety and feasibility of IL-8 receptor modified patient-derived activated CD70 CAR T cell therapy in CD70+ adult glioblastoma
Newly diagnosed CD70 positive adult GBM patients who have undergone surgery for maximal debulking will be enrolled in this 3+3 design dose-escalation clinical trial and undergo peripheral venipuncture for collection of PBMCs for generation of investigational 8R-70CAR T Cell vaccine. Patients will then undergo standard of care chemoradiation. Immunotherapy will begin 2 weeks (-7/+4 days) after completion of radiation. One single dose of 8R-70CAR T cells will be administered IV. The dose will depend on the enrolling cohort. Dose escalation will follow the traditional 3+3 design.
1,919 studies on the registry are indexed under Glioblastoma; 449 are open to participants now.
This study's planned enrollment of 39 is close to the median of 36 across 1,617 interventional studies indexed under Glioblastoma.

Of its 170 completed or terminated interventional studies of FDA-regulated products, 136 (80%) have results posted.
Counted across the registry records on this site, refreshed daily.
Tumor expression will be scored on a scale of 0 to 3 staining intensity:
0 = Negative
= High level
The criteria for inclusion will be at least 5% of the cells scoring 1+ staining intensity (> 5%, 1+).
Hemoglobin ≥ 10 g/dl. (The use of transfusion or other intervention to achieve Hgb ≥ 10 g/dl is acceptable.)
Creatinine ≤ 1.7 mg/dl
AST ≤ 5 times institutional upper limits of normal for age
Exclusion Criteria (Adult GBM):
Rationale: The need to exclude patients with the immunosuppressive disease or human
Severe, active co-morbidity, defined as follows:
Cohort 1 will receive 1 x 10\^6 cells/kg. Cohort 2 will receive 1 x 10\^7 cells/kg. Cohort 3 will receive 1 x 10\^8 cells/kg. Cohort 4 will receive Cy/Flu + CAR T cells at established maximum tolerated dose.

Single dose of 8R-70CAR T cells administered IV
Also known as: 8R-70CAR T cells
Safety of 8R-70CAR T-cell therapy in adult patients with de novo CD70+ GBM
Defined as ≤ 1 DLT out of 6 patients is observed at the 1x10\^8 cells/Kg dose. Dose-Limiting toxicity (DLT) will be defined as any adverse event attributable (possible, probable, or definite) to the administration of 8R-70CAR T cells and occurring from the time of infusion through 28 days post-infusion.
Time frame: 28 days post-infusion
Feasibility of 8R-70CAR T-cell therapy in adult patients with de novo CD70+ GBM
Feasibility will be defined as the ability to infuse 8R-70CAR T-cell safely in 66.7 % of enrolled patients (patients who signed consent and were deemed eligible for the study).
Time frame: 10 weeks
