Open Label Randomized Phase II/III Trial of Dendritic Cell Immunotherapy Against Cancer Stem Cells in Glioblastoma Patients Receiving Standard Therapy (DEN-STEM)
Open, randomized study of a trivalent dendritic cell therapy compared to standard therapy in primary treated patients with IDH wild-type, MGMT-promotor methylated glioblastoma. The IMP is dendritic cells transfected with mRNA of survivin, hTERT og autologous tumor stem cells derived from tumorspheres.
⁃ All of the following conditions must apply:
• Must be at least 18 years and less than 70 years of age.
• Must be ambulatory with a ECOG performance status 0 or 1
• Must have histologically confirmed glioblastoma IDH wild-type, with unmethylated MGMT-gene promotor, and a candidate for combined radiation therapy and chemotherapy (Stupps Regimen).
• Must have accessible volume and quality of tumor tissue for vaccine production (proliferation of cells and extraction of tumor mRNA) at first surgery.
• Must have postoperative MRI after surgery with contrast enhancing tumor remnant of less than 1 cm3 or less than 10% of original tumor volume.
• Normal organ function defined by laboratory values as following: ANC \> 1.5 x 109/L; platelets \>100 x109/L, Hb \>9g/dL (\> 5.6 mmol/L). Creatinine \< 140 µmol/L (1.6 mg/dL); if borderline, the creatinine clearance \>40 mL/min, Bilirubin \< 20% above the upper limit of normal, ASAT and ALAT \< 2.5 the upper limit of normal. Albumin \>2.5 g/L.
• Serology indicating contagious HIV, HBV, HCV and Treponema pallidum must be negative.
• Signed informed consent and expected cooperation of the patients for the treatment and follow up must be obtained and documented according to ICH GCP, and national/local regulations.
