IL13Rα2 CAR-T for Patients With r/r Glioma

Interleukin 13 receptor subunit alpha-2 (IL13Ra2A) is a high-affinity membrane receptor of the anti-inflammatory Th2 cytokine IL13, which is overexpressed in glioma and correlated with poor prognosis. Chimeric antigen receptor (CAR) T cell therapy is a promising treatment approach for many malignancies. IL13Ra2-targeted CAR-T cells are under investigation in several clinical trials in primary CNS malignancies. The investigators now designed a new structure CAR targeted IL13Ra2, and initiated a single arm, open, dose exploration clinical trial to evaluate the safety, tolerability, clinical efficacy, and pharmacokinetic characteristics of IL13Rα2 CAR-T for patients with glioma. This clinical trial will enroll 12-30 cases of patients with IL13α2-positive recurrent or refractory WHO grade 4 glioma (r/r WHO4 glioma), aiming to find the maximum tolerable dose (MTD), the recommended phase 2 dose (RP2D) and preliminary efficacy of the new structure IL13Ra2 CAR-T.
