The Safety and Efficacy of SNC-109 CAR-T Cells Therapy the rGBM

Phase 1
Conditions
Recurrent Glioblastoma Multiforme (GBM)
Interventions
Registration Number
NCT06616727
Lead Sponsor
Shanghai Simnova Biotechnology Co.,Ltd.
Brief Summary

A phase I study to evaluate the safety, tolerance and pharmacokinetics of SNC109 in patients with rGBM

Detailed Description

It is planned to recruit about 50 patients with rGBM subjects. The protocol consists of screening period, Lymphocytes apheresis period, Operation period, pre-infusion evaluation (-2\~-1 days), infusion (day 0), infusion observation (day 1-post infusion), and follow-up period (last infusion-720 days). The incidence of dose limitation toxicity (DLT) will be observed within 28 days after the first infusion. Subjects in this study will receive multiple infusions, starting with 5×104 CAR+ T cells/dose in the first subject, and the Safety Review Committee (SRC) will evaluate the subsequent dosing regimen, dose, infusion interval, and number of treatment cycles. Subsequent subjects will be evaluated by the SRC on the basis of available PK and safety data, and the SRC will determine the dosing regimen, dose, infusion interval and number of treatment cycles based on observed evidences.
