Glyburide Healthy Volunteer Study
A Phase 1 study testing Glyburide in people with Healthy Volunteers, run by Washington University School of Medicine at 1 site in United States.
Trial summary
Glyburide is a medication that has been safely used for several decades to treat non-insulin dependent diabetes. This pilot study seeks to evaluate whether glyburide, administered at the lowest dose (1.5 mg/dL daily) to healthy (non-diabetic) subjects is safe both physically and cognitively.

About this study
Glyburide is a medication that has been safely used for several decades to treat non-insulin dependent diabetes. This pilot study seeks to evaluate whether glyburide, administered at the lowest dose (1.5 mg/dL daily) to healthy (non-diabetic) subjects is safe both physically and cognitively. The investigators are hopeful that the results of this study will provide the necessary foundation to evaluate this medication's use on a larger scale to determine the feasibility of using glyburide in soldiers either prophylactically or for the treatment of brain injury.
Read the detailed description
This study is a placebo controlled (2:1 drug vs. placebo), randomized clinical trial of 21 healthy, non-diabetic volunteers receiving daily doses of oral glyburide (1.5 mg) vs. placebo while under careful medical monitoring in an inpatient Clinical Research Unit (CRU)within the Center for Applied Research Sciences (CARS) at the Washington University in St. Louis Medical Center for a duration of 7 days and nights (24 hours per day). Interested subjects who call for more information about the study will be scheduled for a screening visit. Subjects will participate first in an informed consent process, and those wishing to take part will be asked to undergo a comprehensive interview detailing their past medical history and formal physical examination (which includes laboratory tests of the urine and blood). If a subject is deemed appropriate by the team, he/she will be asked to perform an exercise test (treadmill for 30 minutes) and will have an Electrocardiogram (ECG) completed to further determine eligibility. Individuals who do not meet inclusion criteria based on screening activities will be notified immediately that they are not eligible. Volunteers meeting all eligibility criteria will be scheduled for the week long in-patient evaluation.
Each subject will undergo a battery of physical, cognitive, and laboratory tests in addition to receiving oral glyburide or placebo each day for one week.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants with Adverse Events
The primary objective of this study is to evaluate the safety of glyburide in healthy, non-diabetic volunteers while simulating strenuous activity to observe for any adverse events (i.e. hypoglycemia, dizziness, confusion, etc.). Neuropsychological testing, physical exams, vital signs, ECGs, cognitive assessments, and laboratory values (including serum glucose levels collected 4 x's per day and as needed) will be conducted throughout the 7 day in-patient study to assess for any adverse/serious adverse events.
Measured: 7 days
Secondary outcomes (1)
Cognitive impact
Determine the impact after 7 days of glyburide 1.5mg daily (with breakfast) in healthy volunteers who are able to participate in scheduled strenuous activities and adhere to a structured meal plan on cognitive performance using a computer program to test cognition before study drug administration and at the end of the study in addition to daily physical examinations which include mini mental status exams.
Measured: 7 days

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Glyburide in people with Healthy Volunteers, run by Washington University School of Medicine at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 16 Sep 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants with Adverse Events (time frame: 7 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Sep 2014.
