PHASE1

Dual-Targeting CAR-NK Cells for Recurrent/Progressive Glioblastoma and High-Grade Glioma

Sponsor: Beijing Biotech

View on ClinicalTrials.gov

Summary

This is a draft, ClinicalTrials.gov-style example record for a first-in-human Phase 1 study evaluating 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). Participants will undergo tumor antigen profiling for IL13Rα2, EGFR/EGFRvIII, and B7-H3 (CD276). Based on this assessment, each participant will receive the most suitable dual-target CAR construct to reduce antigen-escape risk.

Official title: A Phase 1, First-in-Human, Biomarker-Guided, Dose-Escalation and Expansion Study of Locoregional Dual-Targeting CAR-NK Cells Directed Against IL13Rα2, EGFR/EGFRvIII, and/or B7-H3 (CD276) in Adults With Recurrent or Progressive Glioblastoma or High-Grade Glioma

Interventions

BIOLOGICAL

Dual-target CAR-NK cells

Dual-target CAR-NK cells (IL13Rα2/EGFR/EGFRvIII construct): Allogeneic natural killer (NK) cells genetically engineered to express a chimeric antigen receptor (CAR) designed to recognize tumor-associated antigens including IL13Rα2, EGFR, and EGFRvIII. This multi-targeting strategy aims to enhance tumor recognition, reduce antigen escape, and improve cytotoxic activity against heterogeneous tumor cell populations. The engineered CAR-NK cells are administered via locoregional delivery (e.g., intracavitary or through an Ommaya reservoir) to achieve targeted anti-tumor effects while minimizing systemic toxicity.

DRUG

Cyclophosphamide

An alkylating chemotherapy agent used as part of lymphodepleting conditioning prior to CAR-NK cell infusion to enhance cell expansion, persistence, and anti-tumor activity.

DEVICE

Intracranial catheter/reservoir for locoregional delivery

A device (e.g., Ommaya reservoir) implanted in the brain to enable direct, repeated administration of CAR-NK cells or other therapies into the tumor site or cerebrospinal fluid, improving local drug delivery and reducing systemic exposure.

DRUG

Fludarabine

A purine analog chemotherapy used in lymphodepletion prior to CAR-NK cell therapy to enhance the expansion, persistence, and anti-tumor activity of the infused cells.

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.
