A Drug-Drug Interaction Study of GK Activator (2) and Glyburide in Patients With Type 2 Diabetes.
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.
