About

This is a single-center, single-arm, open label and dose escalation clinical study of anti-CD147 CART cells in patients with recurrent malignant glioma.

Full description

Patients autologous T cells are activated and then engineered to express chimeric antigen receptors (CARs) specific for CD147(CD147-CART). CAR-T cells are expanded in culture and returned to the patient by Ommaya Reservoir at specific cell doses. Three CD147-CART doses patient are planned at 1-week intervals. Serum cytokine level and CAR-T cell number will be measured in whole treatment session.

Enrollment: 31 estimated patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Age ≥ 18 year and ≤ 65 years, both male and female;
2. Recurrent glioblastoma patients confirmed by histology or cytology, which have received standard care of STUPP protocol (TMZ concurrent chemoradiotherapy and adjuvant chemotherapy protocol) after surgery;
3. Cerebral ventricle was not opened after glioma surgery;
4. More than 6 months after the first glioma surgery;
5. Tumor lesions that can be evaluated or measured according to RANO criteria (Measurable enhancement lesions were defined as enhancement lesions with clear upper boundary of CT or MRI, capable of developing on ≥2 axial films with layer thickness of 5 mm, and the length and diameter of each other were >10 mm. If the scanning layer thickness is large, the minimum measurable lesion should be >2 times thick);
6. CD147+ was confirmed by histologically diagnosis (IHC staining).
7. Adequate PBMC can be obtained according to the requirements of cell preparation, and there are no other contraindications for lymphocyte collection;
8. KPS score ≥70;
9. Patient with a life expectancy of greater than three months;
