When the initial study of this vaccine was conducted at the University of California, Los Angeles, two-thirds of the patients were still alive after two years, compared to one-third who only received standard treatment. In two-fifths of the vaccine-treated patients, who survived two years there has been no evidence of the disease, the study said.
The vaccine is made by taking a portion of a patient's brain tumor and combining it with dendritic white blood cells. Once the vaccine is injected beneath the skin of the patient it should create an immune reaction resulting in killing the cancer cells.
Patients who are candidates for this phase II trial must be newly-diagnosed, and have not had any other treatment, including chemotherapy and/or radiation. They will first undergo a minimally-invasive procedure to remove the tumor, Kelly said.
