Safe Study of Dendritic Cell (DC) Based Therapy Targeting Tumor Stem Cells in Glioblastoma

Phase 1

Completed

• Conditions: Brain Tumor; Glioblastoma

• Registration Number: NCT00846456
• Lead Sponsor: Oslo University Hospital

Brief Summary

The study induces an immune response towards the stem-cell like part of glioblastomas in combination with standard therapy. The aim is to define and characterize the feasibility, potential adverse effects of such therapy and measure time to progression and survival.

Inclusion Criteria

• Accessible volume and quality of tumor tissue for vaccine production
• MRI after surgery with minimal tumor remnant.
• Between 18 and 70 years of age.
• Must have histologically confirmed glioma grade IV, and a candidate for combined radiation therapy and chemotherapy ("Stupps regimen").

Exclusion Criteria

• Tumor in a localization where a modest increase in size due to reactive oedema may have a large impact on patients neurological condition.
• Large tumor remnant after surgery.
• History of prior malignancy other than glioma, with the exception of curatively treated basal cell or squamous cell carcinoma of the skin and ca. cervicis stage IB.
• Chronic active infection requiring antibiotic therapy.
• Significant cardiac or other medical illness that would limit activity or survival, such as severe congestive heart failure, unstable angina, or serious cardiac arrhythmia.
• Prior splenectomy.
• Glucocorticoid treatment not possible to terminate due to autoimmune disease or increased intracranial pressure.
• Adverse reactions to vaccines such as asthma, anaphylaxis or other serious reactions.
• History of immunodeficiency or autoimmune disease such as rheumatoid arthritis, systemic lupus erythematosus, scleroderma, polymyositis- dermatomyositis, juvenile onset insulin dependent diabetes, or a vasculitic syndrome.
• Chemotherapy or other potentially immune-suppressive therapy that has been administered within 4 weeks prior to vaccination.
• Pregnancy or lactation.
• Any reason why, in the opinion of the investigator, the patient should not participate.
