A Pilot Study to evaluate the pharmacokinetic, pharmacodynamic, and resistance profile to trametinib and dabrafenib in BRAF-V600E mutated recurrent gliomas
This research is being done to understand how much of two drugs (dabrafenib and trametinib) is able to enter brain tumors and how well the drugs are able to turn off this pathway in brain tumors. The study will also look at how tumors lose sensitivity to this treatment. People with primary brain tumors who are already taking dabrafenib and trametinib and who need a brain surgery are eligible for this study. Biospecimens (tissue, blood, and cerebrospinal fluid (CSF)) taken during the surgery will help us understand how much of these two study drugs actually get into the brain, their effect, and how the tumors become resistant to treatment.
