Brief Summary

This is a Phase 1 study of recurrent glioblastoma locoregional adoptive therapy with autologous peripheral blood T cells lentivirally transduced to express a dual-target, truncated IL7Ra modified chimeric antigen receptor (CAR), delivered by Ommaya reservoir, a pre-indwelled catheter in the tumor resection cavity. Patients with recurrent glioblastoma will have surgical treatment and pathological test for target expression at their home institution or at Beijing Tiantan Hospital. If the tumor is target positive and the patient meets all other eligibility criteria, and meets none of the exclusion criteria, will have Ommaya reservoir implantation, and a subsequent Peripheral Blood Mononuclear Cells (PBMCs) collection. T cells will then be isolated from the PBMC sample and then be bioengineered in to a 4th generation CAR-T cell, Tris-CAR-T cells. Recipients with Ommaya reservoir implanted will be assigned to three courses. The first 2 patients will be assigned to low dose group, and will have one dose of autologous Tris-CAR-T cells delivery via Ommaya reservoir. The second 2 patients will be assigned to high dose group, and will have one dose of autologous Tris-CAR-T cells delivery via Ommaya reservoir. The last 4 patients will be assigned to multidose group, and will receive a weekly dose of autologous Tris-CAR-T cells for maximum 8 weeks. All patients will undergo studies including MRI to evaluate the effect of the CAR-T cells, physical examination and cerebrospinal fluid cytokine assays to evaluate side effects. All patients will undergo a long-term follow-up. The hypothesis is that an adequate amount of Tris-CAR-T cells can be manufactured to complete all the three courses. The other hypothesis is that Tris-CAR-T cells can safely and effectively be administered through Ommaya reservoir to allow the CAR-T cells to directly interact with the tumor cells for each patient enrolled on the study. The primary aim of the study will be to evaluate the safety of Tris-CAR-T administering. Secondary aims of the study will include to evaluate CAR-T cell distribution within cerebrospinal fluid and peripheral blood, tumor progress post CAR-T cell infusion, and, if tissues samples from multiple time points are available, also evaluate the degree of target expression, biological characteristics of samples at diagnosis versus at recurrence or progression.

Detailed Description

The autologous Tris-CAR-T cell, targeting both CD44 and CD133, the two inverse correlated targets, introduced truncated IL7Ra to the intracellular domain of CAR molecule, has shown ideal survival and tumor suppression in our previous studies. The cells will be tested for safety and kinetics in this clinical trial. All patients are required to have an Ommaya reservoir in tumor resection cavity prior to CAR-T cell infusion. Ommaya reservoir placement is done by a surgery. Autologous Tris-CAR-T cell will be manufactured via CliniMACS Instrument (Miltenyi Biotec). Cells will be frozen and stored to infuse to the patients. Each infusion will take between 5 and 10 minutes. We will then monitor the patient in the hospital for at least 3 days post the first dose of infusion. If the first infusion is tolerated well and the patient is assigned to multidose group, a second infusion may be given 7 days after the initial infusion and patient will be monitored in the hospital for no longer than 1 day. And the subsequent infusion will be done in the same manner. The treatment will be given by the Department of neurosurgery, Beijing Tiantan hospital. If patient is receiving a single dose of the cells, the patient will be monitored at least 3 days after the infusion. Patients assigned to multidose group will be needed to stay in Beijing for up to 8 weeks from the first infusion so we can monitor for side effects and will be readmitted to the hospital if patient develops a fever. If patient develops severe fevers after discharge from the hospital, patient will be readmitted to the hospital for close monitoring for at least one night during safety observation Patients receive single dose infusion will have follow-up visits at weeks 2, 3, 4, then at months 3, 6,9 post infusion. Patients receive multiple dose infusion will have follow-up visits at week 2, then at months 1, 3post infusion. All patients receive long-term twice a year for a total of 15 years. Medical tests before treatment-- Before being treated, the patient will receive a series of standard medical tests: Physical exam Blood routine, serum biochemical test, kidney and liver function Measurements of the tumor by routine MRI Medical tests during and after treatment-- The patient will receive standard medical tests when they are getting the infusions and afterwards: Physical exams Blood routine, serum biochemical test, kidney and liver function, serum and (or) cerebrospinal fluid analysis Measurements of the tumor by MRI. Cerebrospinal fluid may be drawn from the patient's existing Ommaya reservoir preferentially, or via lumbar puncture before each infusion and at each time of follow-up. This procedure can be done at the bedside under local anesthesia and about 1ml of cerebrospinal fluid will be removed. Additional cerebrospinal fluid may be removed when intracranial hypertension occurs or other clinical needs. To learn more about pharmacokinetics of autologous Tris-CAR-T cell, peripheral blood will be obtained simultaneously with cerebrospinal fluid collection. The amount of blood taken will be based on clinical need, for approximately 5 mL each time. If the tumor samples of the patients are obtained, we will request a sample to be used for research purposes. The patient will receive supportive care for any acute or chronic cytotoxicity, including blood components, cytokine antagonist, glucocorticoid, antibiotics, and other intervention as appropriate.

Intervention Description

Intratumorally administrate via Ommaya reservoir. Dose level 0: 1×10^7 autologous Tris-CAR-T cells, one dose, 2 patients. Dose level 1: 1×10^8/ 5×10^6autologous Tris-CAR-T cells, one dose, 2 patients. The dose of Dose level 1 will refer to the adverse effect of Dose level 0. When 1 of the 2 patients in the Dose level 0 had dose-related toxic side effects, 2 patients in the Dose level 1 could be enrolled. When dose-related side effects occurred in 2 patients in the Dose level 0, the dose should be reduced to 5×10^6cells to continue enrollment. Dose level2: 5×10^7 autologous Tris-CAR-T cells, weekly administered, maximum 8 weeks, 4 patients. If the results of Dose level 0 and 1 suggested that dose-related toxic side effects could be occurred in the 1×10^7cells dose, the researcher would re-determine the dosage of the multidose clinical exploration study.
