This first-in-human Phase 1 study evaluates locoregional administration of dual-targeting chimeric antigen receptor natural killer (CAR-NK) cells in adults with recurrent or progressive glioblastoma (GBM) or other high-grade glioma (HGG) after standard therapy. Participants undergo tumor antigen profiling for IL13Ra2, EGFR/EGFRvIII and B7-H3 (CD276), and each receives the most suitable dual-target CAR construct to reduce the risk of antigen escape; delivery uses an intracranial catheter or reservoir alongside cyclophosphamide and fludarabine. Eligible patients are aged 18 to 75 with histologically confirmed glioblastoma (WHO grade 4) or diffuse high-grade glioma (WHO grade 3 or 4) and a planned clinically indicated tumor resection or stereotactic biopsy.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
Inclusion Criteria: * Age 18 to 75 years at the time of consent. * Histologically confirmed glioblastoma (WHO grade 4) or diffuse high-grade glioma (WHO grade 3 or 4) that is recurrent or progressive after standard therapy. * Planned clinically indicated tumor resection or stereotactic biopsy (or availability of adequate archived tumor tissue) to support antigen testing and locoregional catheter placement. * Tumor demonstrates expression of at least two of the following antigens above protocol-defined thresholds: IL13Rα2, EGFR (wild-type) and/or EGFRvIII, B7-H3 (CD276). * Karnofsky Performance Status (KPS) ≥ 60. * Adequate organ function (hematologic, renal, hepatic) as defined by protocol laboratory criteria. * Ability to undergo brain MRI with contrast (unless contraindicated and alternative imaging is permitted). * Negative pregnancy test for women of childbearing potential; agreement to use effective contraception during study participation and for a protocol-defined period after infusion. * Ability to understand and willingness to sign informed consent. Exclusion Criteria: * Active, uncontrolled infection (including uncontrolled bacterial, viral, or fungal infection). * Known HIV infection with uncontrolled viral load; active hepatitis B or hepatitis C with detectable viral load (unless permitted per protocol). * Clinically significant autoimmune disease requiring systemic immunosuppression within the past 6 months. * Requirement for high-dose systemic corticosteroids (e.g., \>4 mg/day dexamethasone equivalent) within 7 days prior to lymphodepletion/infusion (physiologic replacement permitted). * Prior gene-modified cellular therapy (e.g., prior CAR-T/CAR-NK) within 6 months, or prior therapy targeting IL13Rα2, EGFR/EGFRvIII, or B7-H3 where residual engineered cells could confound safety assessments. * Diffuse leptomeningeal disease as the only site of disease, or anatomy that precludes safe catheter placement (unless specifically allowed by protocol). * Uncontrolled seizures despite optimal medical therapy. * Clinically significant cardiovascular disease (e.g., recent myocardial infarction, uncontrolled arrhythmia) that would increase risk with lymphodepletion or infusion procedures. * Pregnant or breastfeeding. * Any condition that, in the investigator's judgment, would make the participant unsuitable for the study or could interfere with protocol adherence.
