E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
• To investigate the effects of four weeks of bi-daily dosing of XEN-D0501 (4 mg BID) as add-on to metformin on fasting blood glucose in patients with diabetes mellitus type 2 |
|
E.2.2 | Secondary objectives of the trial |
• To investigate the effects of bi-daily doses of XEN-D0501 on self-monitored blood glucose (SMBG) concentrations during an 8-point profile in patients with diabetes mellitus type 2 • To investigate the effects of bi-daily doses of XEN-D0501 on plasma HbA1c in patients with diabetes mellitus type 2 • To investigate the effects of bi-daily doses of XEN-D0501 on the glucose tolerance of patients with diabetes mellitus type 2 during a 2 h oral glucose tolerance test (OGTT) in patients with diabetes mellitus type 2 • To investigate the effects of bi-daily doses of XEN-D0501 (4 mg) on insulin secretion during a 2 h oral glucose tolerance test (OGTT) in patients with diabetes mellitus type 2 • To investigate the effects of bi-daily doses of XEN-D0501 on beta-cell function during a 2 h oral glucose tolerance test (OGTT) in patients with diabetes mellitus type 2 |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. The subject must give his/her signed and dated informed consent before any trial-related activities. Trial-related activities are any procedures that would not have been performed during the normal management of the subject 2. Diagnosis of type 2 diabetes mellitus 3. In treatment with a stable metformin dose during the last three months, but no other anti-diabetic drugs 4. HbA1C (glycosylated haemoglobin A1C): 6.5-10 % 5. Age above 25

E.4 | Principal exclusion criteria |
1. A subject with a history of significant multiple drug allergies or with a known or suspected allergy to the trial product or any medicine chemically related to the trial product, as judged by the Investigator 2. A subject who has a clinically significant abnormal ECG at screening, as judged by the investigator 3. A subject who has participated in any other trials involving investigational products within the 3 months preceding the start of dosing 4. A subject who has donated any blood or plasma in the past month or in excess of 500 mL within 1 month preceding screening 5. A subject who has a significant history of alcoholism or drug/chemical abuse as per investigator’s judgement 6. A subject with mental incapacity or language barriers which preclude adequate understanding or cooperation, who is unwilling to participate in the trial, or who in the opinion of their general practitioner or the Investigator should not participate in the trial 7. Surgery or trauma with significant blood loss within the last 2 months prior to dosing 8. A subject with a clinically significant abnormal haematology or biochemistry tests at screening visit, as judged by the Investigator considering the underlying disease 9. Current treatment with drugs known to interfere with glucose metabolism such as systemic corticoids and monoamine oxidase inhibitors (MAO) inhibitors 10. Haemoglobin < 6.2 mmol/l (<99.8 g/l), total leukocyte count < 3.0 x 109/l, thrombocytes <100 x 109/l, serum creatinine levels ≥ 126 μmol/l (male) or ≥ 111 μmol/l (female), bilirubin > 3 x ULN, alanine aminotransferase > 2 x the upper limit of normal (ULN), alkaline phosphatase > 2 x ULN, one re-test within a week is permitted 11. Previous participation (randomisation) in this trial 12. Any condition that would interfere with trial participation or evaluation of results, as judged by the investigator and/or sponsor 13. Recurrent major hypoglycaemia or hypoglycaemic unawareness, as judged by the Investigator 14. Females of childbearing potential (i. e. not post-menopausal ≥ 12 months or surgically sterilised) who are pregnant, breast-feeding or intend to become pregnant or are not using adequate contraceptive methods (adequate contraceptive measures include sterilisation, hormonal intrauterine devices, oral hormonal contraceptives (p-pills), implantants, transdermal patches, p-ring or depot injection, sexual abstinence or vasectomised partner). A male subject who is sexually active and has not been surgically sterilised must be informed that he must ensure that his partner practices effective contraception, as stated above, or he must refrain from sexual intercourse during the trial and until 90 days after completion of the trial. This is to prevent the possibility of a pregnancy from spermatocytes that can potentially be damaged by trial medication |
