Kokeellinen: Neoantigen DC Vaccine (YS247) for Glioblastoma
This is a single-center, open-label, dose-escalation, multiple-dose investigator-initiated trial (IIT).
The trial aims to evaluate the safety and tolerability of autologous dendritic cell injection sensitized with tumor neoantigens (YS247) in participants with recurrent or progressive glioblastoma, as well as to assess preliminary efficacy and pharmacodynamic characteristics.
The study consists of four phases: screening, baseline, treatment, and follow-up.
During the treatment phase, participants will be assigned to three dose groups (low, medium, and high) and enrolled following the "3+3" dose-escalation principle.
YS247 will be administered subcutaneously once every 2 weeks for a total of 8 consecutive doses.

Safety and Treatment Tolerability
Aikaikkuna: From subject enrollment until completion of the 8th treatment cycle (each cycle is 14 days)
|
Evaluate the incidence of treatment-related adverse events (TRAEs) of Tumor Neoantigen-pulsed Autologous Dendritic Cell Injection (YS247, Beijing YSCell Biotech Co., Ltd., abbreviated as YS) in patients with recurrent or progressive glioblastoma based on CTCAE v5.0, to assess the safety and tolerability of the product.

|
|
Maximum Tolerated Dose (MTD) and Recommended Expanded Dose(RP2D)
Aikaikkuna: From subject enrollment until completion of the 8th treatment cycle (each cycle is 14 days)
|
Based on the incidence of dose-limiting toxicities (DLTs), establish the MTD of Tumor Neoantigen-pulsed Autologous Dendritic Cell Injection (YS247) for patients with recurrent or progressive glioblastoma, and define the RP2D. DLT is defined as any study drug-related AE (per CTCAE 5.0) or laboratory abnormality occurring from first dose to 4 weeks post-dose, unrelated to disease progression, comorbidity, or concomitant medication, including:
