The brain is separated from the rest of the blood stream by the blood-brain barrier. This is like a filter that protects the brain. But is also a challenge when medicines need to get into the brain. Researchers want to give the new drug LB100 to people before brain tumor surgery. They will measure how much LB100 is in the blood and how much gets into the brain. This may help with the use of LB100 to treat brain tumors in the future.
To see if LB100 can pass into the brain.
People at least 18 years old with a brain tumor that requires surgery
Participants will be screened with:
Tumor sample. This can be from a previous procedure.
Participants will have their brain surgery at the Clinical Center.
Participants will get a dose of the study drug through a plastic tube in a vein for 2 hours during surgery.
Participants will have blood taken 7 times in the 8 hours after getting the study drug.
Tumor samples will be taken during surgery.
Participants will have a heart test after getting the study drug. Sticky pads on the skin will measure electrical activity of the heart.
Two-three weeks after leaving the hospital, participants will have a follow-up visit. They will have a physical exam and blood tests.
One month after surgery, they will be contacted in person or by phone to see how they are doing.

Treatment with LB100
LB-100 will be infused over 2 hours via IV infusion 2 to 4 hours before surgery. The dose established from a Phase I study will be 2.33 mg/m2.
- Drug Level in tumor tissue [ Time Frame: Post Surgery ]To determine the pharmacokinetic properties of LB100 in glioblastoma tumor tissues
- Relationship between drug concentration at the site of action and the resulting effect and the presence of correlation to identify predictive markers. [ Time Frame: 8 hours post infusion ]Intra-patient PD effect in PBMC and tumor tissue will be evaluated in all subjects for presence of correlation to identify potential predictive markers
- Plasma concentration and calculated LB100 [ Time Frame: 8 hours post infusion ]determine the plasma concentration and calculated PK parameters of LB100 and LB100M (endothall).
- Concentration of LG100 and its major metabolite LB100 in glioblastoma tumor tissue [ Time Frame: 8 hours post infusion ]determine the concentration LB100 and its major metabolite, 7-oxabicyclo [2.2.1] heptanes-2,3-dicarboxylic acid (LB100M) in glioma tumor tissue when a known non-toxic dose of LB100 is delivered intravenously over 2 hours
- Changes in phospho-protein expression in circulating PBMC [ Time Frame: 8 hours post infusion ]determine changes in phospho-protein expression in circulating PBMC
