The purpose of this study is to determine whether AZD1656 will affect the pharmacokinetics (PK) of digoxin in type 2 diabetes mellitus (T2DM) patients.

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

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: 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 of Digoxin During Co-administration With AZD1656

Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • evaluate the pharmacokinetics of digoxin after a single dose when administered alone and in combination with AZD1656 at steady state, by assessment of AUC and Cmax of digoxin [ Time Frame: Serial PK blood samples will be taken on days 4-8 during the treatment periods ]

Secondary Outcome Measures:
  • evaluate the safety of AZD1656 in combination with digoxin 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. ]
  • describe the pharmacokinetics of AZD1656 and its metabolite during concomitant digoxin administration by assessment of AUC(0-24), Cmax, Ctrough, tmax, t1/2 and CL/F (AZD1656 only). [ Time Frame: Serial PK blood samples will be taken on days 4-8 during the treatment periods ]
  • describe the pharmacokinetics of digoxin when administered alone or in combination with AZD1656 by assessment of tmax and t1/2. [ Time Frame: Serial PK blood samples will be taken on days 4-8 during the treatment periods ]
