| Main Objective: The primary objective is to compare the effect on glucose control of 4 different AZD1656 dosing regimens with placebo in type 2 diabetes mellitus patients on metformin treatment, as evaluated by the difference in HbA1c between baseline and final visit at 4 months. Extension Objectives: - To investigate the safety and tolerability of AZD1656 compared to placebo and glipizide after 6 months by assessments of adverse events occurring during the study (including hypoglycaemic events), blood pressure, pulse, physical examination, body weight, safety laboratory variables and electrocardiogram. - To evaluate other cardiovascular risk factors, such as total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides and creactive protein, after 6 months in patients receiving AZD1656 as add-on treatment to metformin compared to placebo as add-on treatment to metformin. ;Secondary Objective: •To characterise the population pharmacokinetic and pharmacodynamic properties of AZD1656 in T2DM patients treated with metformin by utilisation of non-linear mixed effects modelling methodology. •To evaluate other variables of glucose control after 4 months in patients receiving AZD1656 as add-on treatment to metformin compared to placebo as add-on treatment to metformin. •To evaluate other cardiovascular risk factors after 4 months in patients receiving AZD1656 as add-on treatment to metformin compared to placebo as add-on treatment to metformin. •To investigate the safety and tolerability of AZD1656 compared to placebo and glipizide by assessments of adverse events occurring during the study (including hypoglycaemic events), blood pressure, pulse, physical examination, body weight, safety laboratory variables and electrocardiogram. •To explore the safety and tolerability of AZD1656 in patients with severely impaired glucose control during a 4 months treatment period.;Primary end point(s): Change in HbA1c from baseline to the fi | — |
