Conditions

Glioblastoma

Outcome Measures

Primary Outcomes (1)

  From the date of glioblastoma (GBM) surgery until death from any cause, assessed up to 36 months.

Secondary Outcomes (1)

• Progression-Free Survival (PFS)

  From date of glioblastoma (GBM) surgery until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 36 months.

Study Arms (1)

Survivin-loaded dendritic cell injection

EXPERIMENTAL

Drug: Survivin-targeted DC Cell Injection

Interventions

Survivin-targeted DC Cell Injection DRUG

The standard treatment regimen for glioblastoma (GBM) is postoperative combined chemoradiotherapy plus adjuvant chemotherapy. Concurrent radiotherapy with temozolomide (TMZ) at 75 mg/m² is administered for 6 weeks in total. After an interval of 4 weeks (28 days), patients proceed to multiple cycles of adjuvant TMZ chemotherapy. Each 28-day cycle consists of oral temozolomide 150-200 mg/m² daily for 5 consecutive days, followed by a 23-day drug holiday, and the regimen is repeated every 28 days. Survivin-targeted DC cell injection regimen The Survivin-targeted DC cell injection is administered on Day 9 (±1 day) after completion of the 6-week standard concurrent chemoradiotherapy. Administration routes include intradermal and intravenous injection. Dosing is performed on Day 0, Day 14 (±1 day) and Day 28 (±2 day), for a total of 3 administrations. The total specification of Survivin-targeted DC cell injection is 6 mL per dose. The dose is divided between intradermal and intravenous route
