Summary
Brief summary (as posted)
B7-H3 is expressed at low levels in normal tissues but overexpressed in various tumor tissues. The ubiquitous expression of B7-H3 in tumors of different grades is a key feature for brain gliomas. The immunohistochemistry study showed that B7-H3 is abundantly expressed on both glioma (especially high-grade glioma) cells and tumor-associated endothelial cells. For GBM, the expression of B7-H3 is intensely positive, especially on tumor cells and vascular endothelial cells, which makes B7-H3 a potential immunotherapeutic target. γδ T cells recognize tumor cells without being restricted by MHC molecules, and thus can be used in allogeneic therapy without the risk of causing graft-versus-host disease. This study is an open-label, single-arm, dose-escalation and dose-expansion clinical study aimed at evaluating the safety and efficacy of allogeneic B7-H3 CAR γδT in patients with malignant glioma.

- Phase 1: Incidence of Adverse Events (AEs)
- timeFrame
- 12 months
- description
- AE is defined as any adverse medical event from the date of the cell infusion to 12 months after B7-H3 CAR-γδT cells infusion. Among them, cytokine release syndrome (CRS) and immune cell-associated neurotoxicity syndrome (ICANS) were graded according to American Society for Transplantation and Cellular Therapy (ASTCT) criteria, graft-versus-host disease (GVHD) according to criteria defined by the Mount Sinai Acute GVHD International Consortium. Other AEs were graded according to common terminology criteria for adverse events (CTCAE) v5.0.
