Immunotherapy + Radiotherapy for Brain Stem Glioma
(BRAVO Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
The standard of care for children with DIPG includes focal radiotherapy (RT) but outcomes have remained dismal despite this treatment. The addition of oral Temozolomide (TMZ) concurrently with RT followed by monthly TMZ was also found to be safe but ineffective. Recent studies in adults have shown that certain types of chemotherapy induce a profound but transient lymphopenia (low blood lymphocytes) and vaccinating and/or the adoptive transfer of tumor-specific lymphocytes into the cancer patient during this lymphopenic state leads to dramatic T cell expansion and potent immunologic and clinical responses. Therefore, patients in this study will either receive concurrent TMZ during RT and immunotherapy during and after maintenance cycles of dose-intensive TMZ (Group A) or focal radiotherapy alone and immunotherapy without maintenance DI TMZ (Group B). Immune responses during cycles of DC vaccination with or without DI TMZ will be evaluated in both treatment groups.

Are You a Good Fit for This Trial?
This trial is for children with a specific brain tumor called DIPG or other diffuse intrinsic brain stem gliomas. They must be stable after surgery, have certain blood and organ function levels, and agree to use birth control if applicable. Those with severe allergies to the drugs used in this study, significant organ dysfunction, unstable medical conditions, or who cannot follow the study procedures are not eligible.Inclusion Criteria
