  Purpose
The purpose of this study is to determine whether AZD1656 will affect the Pharmacokinetics and Pharmacodynamics of Warfarin in T2DM patients.

Condition Intervention Phase
Type 2 Diabetes Mellitus Drug: Warfarin Drug: Placebo Drug: AZD1656 Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open-Label, Randomised, Placebo-Controlled, Two-Way Crossover, Phase I Single Centre Study in Type 2 Diabetes Mellitus Patients Treated With Metformin to Evaluate the Pharmacokinetics and Pharmacodynamics of Warfarin During Co-administration With AZD1656

Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • To evaluate the pharmacokinetics of warfarin after a single dose when administered alone and in combination with AZD1656 at steady state by assessment of AUC and Cmax of both enantiomers of warfarin (S- and R-warfarin). [ Time Frame: Serial PK blood samples will be taken on days 4-10 during the treatment periods ]

Secondary Outcome Measures:
  • To evaluate the anticoagulant activity of warfarin upon co-administration with AZD1656 by assessment of prothrombin time (PT) and international normalised ratio (INR). [ Time Frame: Serial blood samples for warfarin PD measurements will be taken on days 4-10 during the treatment periods ]
  • To evaluate the safety of AZD1656 in combination with warfarin by assessment of electrocardiogram, weight, pulse, blood pressure, laboratory variables (including 7-point glucose), physical examination and adverse events [ Time Frame: Safety assessments will be monitored throughout the study, from screening visit until follow up visit. ]
  • To describe the pharmacokinetics of AZD1656 and its metabolite during concomitant warfarin administration by assessment of AUC0-24, Cmax, Ctrough, tmax, t1/2 and CL/F (AZD1656 only). [ Time Frame: Serial PK blood samples will be taken on days 4-10 during the treatment periods ]
