Trial Summary

Do I need to stop my current medications to join the trial?

The trial does not specify if you need to stop all current medications, but certain drugs are prohibited, especially if you are in regimen B. These include MAOIs, UGT1A9 inhibitors, probiotics, and warfarin. If you are on these, you may need to stop them before joining the trial.

What data supports the effectiveness of the drug combination therapy including Bevacizumab for treating glioblastoma?

Research shows that adding Bevacizumab to radiation therapy and Temozolomide can prolong the time before glioblastoma progresses, although it may not extend overall survival. This combination has been studied for safety and effectiveness, particularly in certain subgroups of patients.12345

Is the combination of Bevacizumab and radiation therapy safe for treating glioblastoma?

Bevacizumab, when combined with radiation therapy, has been linked to safety concerns such as stroke, bleeding, and wound-healing issues, especially in glioblastoma patients. However, studies have shown that while these side effects are known, the combination is generally considered feasible and provides additional safety data for treating high-grade gliomas.24567

What makes this treatment for glioblastoma unique?

This treatment combines bevacizumab, which targets blood vessel growth in tumors, with epacadostat and retifanlimab, which are immune-modulating drugs, alongside radiation therapy. This combination aims to enhance the effectiveness of radiation by inhibiting tumor blood supply and boosting the immune response, offering a novel approach compared to standard treatments.12689

What is the purpose of this trial?

This trial is testing a combination of treatments including a new drug, radiation therapy, and other medications for patients with aggressive brain cancer that has returned. The goal is to boost the body's immune system to better fight the cancer, shrink tumors, and help patients live longer.

Treatment Details

Interventions

  • Bevacizumab
  • Epacadostat
  • Radiation therapy
  • Retifanlimab
Trial Overview The study tests combining retifanlimab with radiation therapy and bevacizumab with/without epacadostat in treating recurrent brain tumors. It aims to enhance anti-tumor immune response and improve survival by leveraging the synergy between radiation therapy and immune modulators.

Findings from Research

In a retrospective analysis of the AVAglio trial involving 921 glioblastoma patients, those with IDH1 wild-type proneural tumors showed a significant overall survival (OS) benefit from bevacizumab treatment compared to placebo, with an OS of 17.1 months versus 12.8 months.
While patients with mesenchymal and proneural tumors experienced progression-free survival (PFS) benefits from bevacizumab, only the proneural subtype demonstrated a corresponding OS advantage, highlighting the importance of molecular subtypes in treatment efficacy.

In a study involving 25 patients with recurrent glioblastoma and anaplastic gliomas, the combination of bevacizumab and hypofractionated stereotactic radiotherapy (HFSRT) was found to be safe and well tolerated, with no cases of radiation necrosis reported.
The treatment showed promising efficacy, with a 50% overall response rate and a median overall survival of 12.5 months, indicating that this regimen could be an effective option for patients with recurrent malignant gliomas.

In a Phase II pilot study involving 10 patients with newly diagnosed glioblastoma, the combination of bevacizumab (BV), temozolomide (TMZ), and regional radiation therapy (RT) showed acceptable safety and tolerability, with some patients experiencing serious toxicities like presumed radiation-induced optic neuropathy and high rates of fatigue and myelotoxicity.
Preliminary results indicated encouraging mean progression-free survival, but further research with more patients and longer follow-up is needed before considering routine use of this treatment combination.
