Radiation Therapy + Bevacizumab for Recurrent Brain Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores the effectiveness of radiation therapy for individuals whose brain tumors have recurred after previous treatment. Researchers aim to determine the optimal radiation dose to maximize cancer cell destruction while monitoring for side effects. Some participants may also receive bevacizumab, a targeted therapy, alongside radiation to assess its potential benefits. Individuals who had a brain tumor treated with radiation at least six months ago and have imaging confirming the cancer's return may qualify for this study. As an unphased trial, this study provides patients the chance to contribute to groundbreaking research that could enhance future treatment options.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but you cannot take chemotherapy drugs during the trial, except for temozolomide or bevacizumab, if your doctor approves.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that radiation therapy for brain tumors is generally safe. Various delivery methods can effectively control tumors while protecting healthy brain tissue. For example, one study found that stereotactic radiosurgery, a precise type of radiation therapy, is safe and positively affects thinking skills.
Regarding bevacizumab, a drug often used for brain cancer, studies suggest it is also safe. In a review of nearly 1,000 patients with recurring glioblastoma (a type of brain tumor), bevacizumab helped manage the disease. Another study found that combining bevacizumab with radiation therapy was safe.
Overall, both radiation therapy and bevacizumab have been well-tolerated by people with brain tumors. While all treatments can have side effects, these treatments have shown a good safety record in previous studies.12345Why are researchers excited about this trial's treatments?
Researchers are excited about the combination of radiation therapy with bevacizumab for recurrent brain cancer because it offers a potential new approach to tackling this challenging condition. Unlike standard treatments that typically focus on either chemotherapy or radiation alone, bevacizumab is an antibody that targets and inhibits VEGF, a protein that promotes blood vessel growth in tumors. By combining bevacizumab with radiation, this treatment aims to enhance the effectiveness of radiation by starving the tumor of the blood supply it needs to grow. This dual approach could potentially improve outcomes for patients by making tumors more susceptible to radiation.
What evidence suggests that this trial's treatments could be effective for recurrent brain cancer?
This trial will compare two treatment approaches for recurrent brain cancer. In one arm, participants will receive radiation therapy with conventional fractionation. Research has shown that radiation therapy can effectively treat brain tumors like glioblastoma, and using standard radiation doses with techniques such as intensity-modulated radiation therapy (IMRT) can extend the lives of patients with aggressive brain tumors. However, for recurrent tumors, the outlook is generally less positive, with average survival times of less than five months.
In the other arm, participants will receive both radiation therapy and bevacizumab. Studies have found that bevacizumab is helpful for treating recurrent glioblastoma, offering about 4.2 months where the disease does not worsen. It can delay disease progression and improve symptoms. While bevacizumab does not significantly increase overall survival time, it can enhance quality of life by reducing symptoms.15678Who Is on the Research Team?

Are You a Good Fit for This Trial?
This trial is for patients with brain tumors that have returned after previous radiation therapy. Eligible participants must have had only one prior round of radiation, may have undergone surgery before re-radiation, and should not be pregnant or have recurrent diffuse intrinsic pontine glioma (DIPG). They need a performance status score of 50-100 and recent imaging showing recurrent disease.Inclusion Criteria
