Tris-CAR-T Cell Therapy for Recurrent Glioblastoma

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 or ventricle. Patients with pathological confirmation of glioblastoma and radiological evidence of recurrence are candidates for this clinical trial. If the patient meets all other eligibility criteria, and meets none of the exclusion criteria, will have leukapheresis, and a subsequent Ommaya reservoir implantation. T cells will be isolated from the PBMC sample and then be bioengineered into a 4th generation CAR-T cell, Tris-CAR-T cells. Recipients will be assigned to three courses in the order of enrollment. The first 2 patients will be assigned to the low-dose group. The second 2 patients will be assigned to the high dose group. The first 4 patients will have at least one dose of autologous Tris-CAR-T cells delivery via the Ommaya reservoir, at a maximum of 6 doses. The interval between the first and the second dose is 28 days, and the rest doses will be administered weekly. The last 6 patients will be assigned to the consecutive multidose group, and will receive a weekly dose of autologous Tris-CAR-T cells for a maximum of 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 the Ommaya reservoir to allow the CAR-T cells to directly interact with the tumor cells for each patient enrolled in the study. The primary aim of the study will be to evaluate the safety of Tris-CAR-T administration. Secondary aims of the study will include evaluating CAR-T cell distribution within cerebrospinal fluid and peripheral blood, tumor progress post-CAR-T cell infusion, and, if tissue 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.
