| E.1.2 Medical condition or disease under investigation |
| E.1.2 | Version | 9.1 |
| E.1.2 | Level | LLT |
| E.1.2 | Classification code | 10045242 |
| E.1.2 | Term | Type II diabetes mellitus |
|
| E.1.3 | Condition being studied is a rare disease | No |
| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| The primary objective is to demonstrate non-inferiority (by means of comparing the upper limit of a two-sided 95% confidence interval with the non-inferiority margin of 1.3) of treatment with linagliptin in comparison to glimepiride (as monotherapy or as add-on therapy) with respect to time to first occurrence of any of the adjudicated components of the primary composite endpoint (i.e. cardiovascular [CV] death, non-fatal stroke, non-fatal myocardial infarction [MI] and hospitalisation for unstable angina pectoris [UAP]) in patients with type 2 diabetes mellitus [T2DM]. If the non-inferiority hypothesis with margin 1.3 has revealed a significant result, then secondly, the primary composite endpoint will be tested with a superiority hypothesis. |
|
| E.2.2 | Secondary objectives of the trial |
| If the superiority test has revealed a significant result, then thirdly the first key secondary endpoint will be tested hierarchically. If the test of the first key secondary hypothesis has revealed a significant result, then fourthly the second key secondary endpoint will be tested hierarchically. |
|
| E.2.3 | Trial contains a sub-study | Yes |
| E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
| Sub-studies are planned that could further advance our understanding of important issues in the management of patients with T2DM related to oral DPP-IV inhibition. The sub-studies currently planned are three: one addressing glycaemic variability and its importance; one addressing cognitive function and factors associated with its decline; and one addressing long term ?-cell function associated with the two different treatment strategies. The sub-studies will be described in separate protocols, which will be reviewed separately by IECs/IRBs and HAs. To date protocols of substudies are not yet available. |

- Proliferative retinopathy defined as retinal neovascularisation or previous retinal laser coagulation therapy.
C) Age ? 70 years (at Visit 1a)
D) At least two of the following CV risk factors:
- Type 2 diabetes mellitus duration > 10 years at Visit 1a.
- Systolic blood pressure (SBP) > 140 mmHg (or on at least one blood pressure lowering treatment at Visit 1a)
- Current daily cigarette smoking
- LDL cholesterol ? 135 mg/dL (3.5 mmol/l) (or specific current treatment for this lipid abnormality) at Visit 1a
3) Body Mass Index (BMI) ? 45 kg/m2 at Visit 1a
4) Age ? 40 and ? 85 years at Visit 1a

| E.4 | Principal exclusion criteria |
? Type 1 diabetes mellitus
? Treatment with other antidiabetic drugs (e.g. rosiglitazone, pioglitazone, GLP-1 analogue/agonists, DPP-IV inhibitors or any insulin) prior to informed consent. Note: previous short term use of insulin (up to two weeks) is allowed (e.g. during hospitalisation) if taken at least 8 weeks prior informed consent.
? Treatment with anti-obesity drugs (e.g. sibutramine, orlistat) within 3 months prior to informed consent
? Any previous (or planned within next 12 months) bariatric surgery (open or laparascopic) or intervention (gastric sleeve)
