About this study
Official title: An Open-label, Crossover Study to Investigate the Potential Pharmacodynamic and Potential Pharmacokinetic Interaction Between Glyburide and GK Activator(2) in Type 2 Diabetes Patients Inadequately Controlled With Glyburide as Standard Prescribed Therapy.
This study will assess the potential pharmacodynamic and potential pharmacokinetic interaction between GK Activator (2) and glyburide, in type 2 diabetes patients not adequately controlled with glyburide as standard prescribed therapy. Patients will enter the study taking a dose of glyburide (10-20mg po daily) as prescribed prior to study start. GK Activator (2) 100mg bid will be added for 5 days. From days 6-12 patients will receive GK Activator (2) monotherapy, and from day 13 GK Activator (2) will be discontinued and glyburide treatment re-started. The anticipated time on study treatment is <3 months, and the target sample size is <100 individuals.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing GK Activator (2) and Glyburide in people with Diabetes Mellitus Type 2, run by Hoffmann-La Roche at 4 sites 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 3 inclusion and 3 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 2 Nov 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites 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. 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?
AUC0-6h of plasma glucose (time frame: Days -1, 6 and 12). The study lists 3 primary outcomes in all. 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 2 Nov 2016.
