Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

- - Subjects must be taking dabrafenib at a dose of at least 50mg twice daily (adults only) and / or trametinib at a dose of at least 1mg daily (adults only) for at least 7 days prior to surgery as prescribed by their treating physician.
- - Subjects must be undergoing surgery for clinical purposes.
- - Written informed consent - a signed informed consent and/or assent (as age appropriate) for study participation will be obtained according to institutional guidelines.
- - Subjects who are receiving any other investigational agents or chemotherapeutic agents.
- - Subjects for whom collection of blood, spinal fluid, or tissue samples is unsafe or clinically inadvisable.
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

The primary goal of this study is to establish concentrations of dabrafenib and trametinib in enhancing brain tissue and cerebrospinal fluid from people with BRAF-V600E mutant recurrent gliomas who undergo tumor resection. The exploratory goals are to measure the amount of ERK signaling pathway activity, to identify mechanisms of resistance to these drugs, and evaluate feasibility of measuring tumor DNA in cerebrospinal fluid. People (adults or children) with brain tumors who are already taking dabrafenib and / or trametinib and are in need of a surgical resection are potentially eligible. On the day of surgery, blood, cerebrospinal fluid, and tumor tissue will be collected for research purposes.
: Surgical Cohort
Blood, cerebrospinal fluid, and tumor tissue will be obtained from each participant on this arm.
Procedure: - Surgical Cohort
Blood, cerebrospinal fluid, and surgical tissue collected during procedure
