A Relative Bioavailability Study Measuring the Extent and Rate of Absorption of Different Tablet Formulations of AZD1656 in Type 2 Diabetes Mellitus (T2DM) Patients

Randomized, Open, 4-way Crossover, Single Center, Phase I Relative Bioavailability Study in Type 2 Diabetes Mellitus Patients to Measure the Extent and Rate of Absorption of AZD1656 From Different Tablet Formulations

The purpose of this study is to assess the relative bioavailability by measuring the extent and rate of absorption of different tablet formulations of AZD1656 in T2DM patients.

Inclusion Criteria:

• Provision of signed and dated, written informed consent prior to any study specific procedures.
• Males or females of non-childbearing potential (post-menopausal, and/or have undergone hysterectomy and/or bilateral oophorectomy or salpingectomy/ tubal ligation) aged ≥18 years. Females will be defined as post-menopausal if last menstruation period was >1 year ago and serum follicle stimulating hormone (FSH) is within the post-menopausal range, or if age >50 years and with last menstruation period >2 years ago.
• A confirmed clinical diagnosis of T2DM for at least 1 year, treated with metformin as a single treatment or in combination with one other oral anti-diabetic (ie, DPPIV inhibitor or SU) for at least 2 months prior to screening. Doses of anti-diabetic treatment should have been stable for at least 1 month prior to screening.
• Treatment with at least 1000mg of Metformin for 2 months and being stable on the Metformin Therapy for 1 month
• Hb A1c >6.5% (international standard) at enrolment.
• Body mass index (BMI) between ≥19 and ≤42 kg/m2.

Exclusion Criteria:

• Clinically significant illness or clinically relevant trauma, as judged by the Investigator, within 2 weeks prior to the first administration of AZD1656
• Participation in another clinical study during the 30 days prior to screening or intake of another investigational drug within 30 days (or at least 5 x t1/2 of the drug) prior to the first administration of AZD1656.
• History of, or ongoing, ischemic heart disease or heart failure. Stroke, transitory ischemic attack, or symptomatic peripheral arterial disease within the last 6 months.
• Clinically significant abnormalities in ECG, clinical chemistry, hematology or urinalysis results.
• Positive test for Hepatitis B surface antigen (HBsAg) or antibodies to human immunodeficiency virus (HIV) or Hepatitis C virus.
