Summary
Brief summary (as posted)
Glioblastoma multiforme (GBM) are the most prevalent malignant tumor in central nervous system. At recurrence, no clear standard-of-care therapy is agreed for recurrent GBM (rGBM) and median overall survival is estimated to rarely exceed 6-9 months with effective therapies. Neoadjuvant therapy with anti-PD-1 monoclonal antibodies were confirmed to be helpful to extend survival in rGBM. Vaccine, dendritic cells (DCs) pulsed with glioblastoma stem-like cell (GSC) antigens (GSC-DCV), could extend survival for GBM patients in our previous clinical study (PMID: 30159779). The purpose of this study is to evaluate the safety and efficiency of using the neoadjuvant therapy with PD-1 antibody (Carilizumab) plus DC vaccine (GSC-DCV) in patients with recurrent glioblastoma.

Inclusion Criteria: 1. Age from 18 to 70 years. 2. Eastern Cooperative Oncology Group (ECOG) performance status of 0,1 or 2. 3. Estimated life expectancy \> 3 months. 4. Previous first-line therapy with radiotherapy and chemotherapy, first or second relapse with unequivocal evidence of tumor progression. 5. Pathological diagnosis or molecular diagnosis for lesion this time was confirmed to be recurrent brain glioma (WHO grade 4). 6. Patients with subtotal resection or above of the tumor confirmed with contrast MR within 72 hours after surgery. 7. No high-dose systemic corticosteroids (defined as \>10 mg day-1 of prednisone or bio-equivalent for at least seven consecutive days before administration). 8. No antibiotics for at least three consecutive days before administration. 9. Adequate organ function defined by: Adequate bone marrow reserve: absolute neutrophil (segmented and bands) count (ANC) ≥ 1.0×10\^9/L, platelets ≥100×10\^9/L; hemoglobin ≥ 8 g/dL. Hepatic: bilirubin 2×upper limit of normal (ULN), aspartate transaminase (AST) and alanine transaminase (ALT) \< 2.5×upper limit of normal (ULN). Renal: Normal serum Creatinine for age (below) or creatinine clearance \>60 ml/min/1.73 m2. Electrocardiogram: normal. 10. Written informed consent. 11. Patient should have good follow-up compliance. Exclusion Criteria: 1. Pregnant or breast-feeding patients. 2. Patients with uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, or psychiatric illness/social situations that would limit compliance with study requirements. 3. Patients with history of immune system abnormalities such as hyperimmunity (e.g., autoimmune diseases) and hypoimmunity (e.g., myelodysplastic disorders, marrow failures, AIDS, ongoing pregnancy, transplant immuno-suppression), or medication of cortisol. 4. Patients with any conditions that could potentially alter immune function (e.g., AIDS, multiple sclerosis, diabetes, renal failure). 5. Any previous investigational medication within 30 days before first administration of Camrelizumab. 6. History of allergy to study drug components or of severe hypersensitivity reactions to any monoclonal antibodies.
