Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Single (Participant)

Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • Safety variables (AE, BP, pulse, plasma glucose, laboratory variables, weight and ECG [ Time Frame: AE will be collected from the time for randomisation until follow-up visit. Safety variables and vital signs will be measured at the pre-entry, during study days -2 to 10 and at the follow-up visit. ]

Secondary Outcome Measures:
  • Pharmacokinetic variables: (Area under the plasma concentration vs. time curve (AUC), maximum plasma concentration (Cmax), time to reach maximum plasma concentration (tmax), terminal elimination half-life (t½) and apparent oral clearance (CL/F) [ Time Frame: Blood samples for analysis of plasma concentrations of AZD1656 will be collected on study days 6 and 9. The samples for analysis of glipizide will be collected on study days -1 and 6. ]
  • Pharmacodynamic variables: 24 h plasma glucose, Insulin [ Time Frame: Samples for 24-hour plasma glucose and insulin will be collected on study days -1, 6 and 9. ]

Enrollment: 75
Study Start Date: October 2009
Study Completion Date: February 2010
Primary Completion Date: February 2010 (Final data collection date for primary outcome measure)
