Overview
This is a dose exploration clinical trial to assess the safety and feasibility of the IL13Ra2-targeted CAR-T in glioma.
Description
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.
Eligibility
Inclusion criteria:
- Male or female aged 18-75 years (including 18 and 75 years old).
- Karnofsky scale score (KPS)≥50.
- Subjects with WHO grade 4 gliomas who have relapsed or progressed during or after standard treatments such as surgery, radiotherapy, and chemotherapy.
- Tumor with IL13Rα2 positive expression.
- Availability in collecting peripheral blood mononuclear cells (PBMCs).
- Adequate laboratory values and adequate organ function.
- Patients with childbearing/fathering potential must agree to use highly effective contraception.
Exclusion criteria:
- Pregnant or breastfeeding females.
- Contraindication to bevacizumab.
- Within 5 days prior to the infusion of CAR-T cells, subjects receiving systemic administration of steroids with dosage more than 10mg/d prednisone or the equivalent doses of other steroids (not including inhaled corticosteroid).
- Comorbid with other uncontrolled malignancy.
- Active immunodeficiency virus (HIV) or hepatitis B virus or hepatitis C virus or tuberculosis infection.
- Autoimmune diseases.
- Severe or uncontrolled psychiatric diseases or condition that could increase adverse events or interfere the evaluation of outcomes.
- Subjects who have previously received cell therapy (such as TCR-T, CAR-T, TIL, etc.).
- Subjects with other conditions that would interfere trial participation at the investigator's discretion.
