In the fight against brain cancer, scientists are turning to the power of the immune system. One promising approach is the brain tumor vaccine, an anti-cancer Immunotherapy designed to train the body to recognize and destroy cancerous cells. Could this revolutionary treatment offer new hope in fighting this devastating disease?
Glioblastoma: The Most Common And Aggressive Brain Tumor
Much of the current brain tumor vaccine research focuses on glioblastoma (GBM), the most common and aggressive type of primary brain tumor. Glioblastoma is a fast-growing cancer that forms from glial cells in the brain and typically has a poor prognosis.
Scientists are also investigating how a brain cancer vaccine like that might be used to treat other types of brain cancer. These vaccines work by ‘teaching’ the body’s immune system to identify specific proteins found on tumor cells, triggering an attack against the cancer.
In the relentless battle against brain cancer, scientists are exploring innovative strategies to harness the power of the immune system. Among these promising approaches is a brain tumor vaccine, a form of immunotherapy that aims to train the body’s natural defenses to recognize and attack cancer cells.
Personalized Brain Tumor Vaccines: A Revolutionizing Approach to Glioblastoma Treatment?
Glioblastoma is an aggressive brain tumor. Surgery is often the first treatment, but it can be difficult to remove all of the tumor. Additionally, traditional treatments like radiation and chemotherapy can have negative side effects. Immunotherapy is a newer treatment option that shows promise for glioblastoma patients.
Biotherapy International, an international cancer center with over 30 years of experience treating brain cancers, is at the forefront of developing cancer vaccines and other immunotherapies for glioblastoma. Recognizing that every cancer case is unique, their goal is to provide patients with treatments based on the latest scientific research to improve their chances of overcoming even the most challenging cancer diagnoses.
By combining personalized cancer vaccines with other cutting-edge therapies like oncolytic viruses, Biotherapy International is working to improve outcomes and extend survival for glioblastoma patients.

Vaccines Targeting Specific Proteins In Brain Tumors
One of the leading contenders in the race for a brain tumor vaccine is MimiVax’s SurVaxM. This vaccine candidate targets survivin, a protein that is overexpressed in cancer cells and plays a crucial role in tumor growth and survival. SurVaxM is administered after surgery and radiotherapy when the tumor burden is low, and the immune system is more responsive. The vaccine is given subcutaneously every two weeks for four doses, followed by a maintenance dose every eight weeks thereafter.
The results from MimiVax’s phase 2a trial in newly diagnosed glioblastomas (GBMs) are encouraging. When used as an add-on to standard therapy, SurVaxM demonstrated a median overall survival of 28.4 months from diagnosis, which is an improvement compared to standard therapy alone. The immune response to the vaccine also shows several characteristics that may serve as useful biomarkers in the future. The U.S. Food and Drug Administration (FDA) has granted SurVaxM both orphan drug and fast track designations for newly diagnosed GBMs, highlighting its potential.
Brain Tumor Vaccines: Still in Experimental Stages
While these results offer great hope, it’s important to remember that brain tumor vaccines are still in experimental stages. Further research and larger trials are needed to confirm their long-term effectiveness.
Building on these promising findings, MimiVax launched a larger, prospective randomized phase 2b trial called SURVIVE (SurVaxM Plus Adjuvant Temozolomide for Newly Diagnosed Glioblastoma) in 2022. The study is currently ongoing at 11 cancer centers across the United States and has been one of the fastest-enrolling trials for this diagnosis, with two-thirds of the patients recruited in just six months, according to MimiVax’s CEO, Michael Ciesielski.
The World’s First Brain Tumor Vaccine
Another breakthrough in brain tumor treatment is DCVax, which is the world’s first brain tumor vaccine. DCVax is produced by combining proteins from a patient’s own tumor with their white blood cells, effectively training the immune system to recognize and fight the cancer. The educated white blood cells help the rest of the immune system identify the tumor as a threat and mount an attack against it.
Although DCVax is not yet available on the National Health Service (NHS) in the United Kingdom, Northwest Biotherapeutics, the U.S. company behind the vaccine, plans to seek regulatory approval to make it more widely accessible. Brain Tumor Research, a charity organization, emphasizes the importance of making DCVax affordable and potentially a standard of care treatment. Glioblastoma patients have had limited new clinical options since the introduction of temozolomide chemotherapy in 2005.
The Future of Brain Tumor Vaccines
As research into brain tumor vaccines continues to advance, there is growing hope that these innovative immunotherapies may offer significant progress in treating brain cancer. One challenge facing the widespread use of brain tumor vaccines is the complexity of their development and the potential for high costs. Personalized cancer vaccines, like DCVax, require the creation of individualized treatments using the patient’s own tumor cells, which can be a time-consuming and expensive process. Highlighting the need to make these therapies more accessible and affordable is crucial to ensure that patients can benefit from these promising treatments.
A Promising Tool in the Fight Against Brain Cancer
The promising results from ongoing clinical trials and the dedication of scientists and medical professionals worldwide bring us closer to this goal. While brain tumor vaccines show great promise, it is essential to recognize that they are not yet a cure and should be seen as a potential tool in the larger fight against brain cancer. With continued research and support, we may one day see brain tumor vaccines become a standard part of treatment, offering new hope to patients and their families. The potential of brain tumor vaccines to revolutionize the treatment landscape and improve patient outcomes is undeniable, but there is still much work to be done to make this a reality.
