Glyburide vs Placebo as Prophylaxis Against Cerebral Edema in Patients

Status Terminated

Clinical Trial Summary

Primary Objectives: Pilot Portion: To determine the feasibility and safety of administering oral glyburide to non-diabetic patients receiving stereotactic radiosurgery (SRS) for newly diagnosed brain metastases. Randomized Portion: To determine the number of patients with newly diagnosed brain metastases who have an increase in edema as measured on volumetric FLAIR imaging and the number of patients that require dexamethasone administration (or any corticosteroid administration with the purpose of treating cerebral edema) from the day of SRS to one month follow-up MRI in the group receiving glyburide versus placebo.

Clinical Trial Description

Many patients with cancer that has spread to the brain have side effects caused by swelling around the tumors. A common treatment for this swelling is a medicine called dexamethasone. Dexamethasone is a steroid. Long-term use of steroids has several known side effects. Recent studies have shown that a drug commonly used in to control high blood sugar in diabetes, called glyburide, can decrease brain swelling in patients with brain damage or stroke. Animal studies have shown that this drug may also reduce swelling from tumors in the brain. Researchers are interested in whether glyburide could treat brain swelling as well as dexamethasone with fewer side effects. This study is being done to see whether glyburide is safe to be used in patients without diabetes in combination with receiving SRS for brain metastases. This study will also find out if glyburide will decrease brain swelling in patients that get radiosurgery (SRS) for brain metastases. This study will also find out if taking glyburide will decrease the chance of needing steroids due to brain swelling that is causing symptoms. It is not yet known, but it is the investigators' hope that glyburide will both decrease brain swelling and lessen the chance of needing steroids. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
