Title: Liraglutide Effect and Action in Diabetes (LEAD-2): Effect on Glycaemic Control After Once Daily Administration of Liraglutide in Combination With Metformin Versus Metformin Monotherapy Versus Metformin and Glimepiride Combination Therapy in Subjects With Type 2 Diabetes
Brief Summary: This trial is conducted in Europe, Oceania, Africa, Asia and South America. This trial is designed to show the effect of treatment with liraglutide when adding to existing metformin therapy and to compare it with the effects of metformin monotherapy and combination therapy of metformin and glimepiride. Two trial periods: A 6 month (26 weeks) randomised, double-blinded period followed by an 18 months open-label extension, in total 2 years (104 weeks).


Options:
A: Eligibility Criteria:

* The major criteria for eligibility included insulin dependence, as evidenced by deficient C-peptide secretion; an age of 13 to 39 years; and the absence of hypertension, hypercholesterolemia, and severe diabetic complications or medical conditions. To be eligible for the primary-prevention cohort, patients were required to have had insulin dependent diabetes mellitus (IDDM) for one to five years, to have no retinopathy as detected by seven-field stereoscopic fundus photography, and to have urinary albumin excretion of less than 40 mg per 24 hours. To be eligible for the secondary-intervention cohort, the patients were required to have IDDM for 1 to 15 years, to have very-mild to moderate nonproliferative retinopathy, and to have urinary albumin excretion of less than 200 mg per 24 hours.
B: Inclusion Criteria:

1. A diagnosis of type 2 diabetes mellitus first made at age 30 years or older
2. Age 55 years or older at entry
3. Ability to provide informed consent
4. A substantially elevated risk of cardiovascular disease, indicated by:

   * A history of major macrovascular disease defined as any one of: stroke, myocardial infarction, hospital admission for transient ischaemic attack, hospital admission for unstable angina, coronary artery bypass graft, percutaneous transluminal coronary angioplasty (with or without stenting), peripheral revascularisation (angioplasty or surgery) or amputation secondary to vascular disease or
   * A history of major microvascular disease defined as any one of nephropathy (albumin:creatinine ratio \>300ug/mg), retinal photocoagulation therapy, proliferative retinopathy (new blood vessels on the disc or elsewhere, vitreous haemorrhage, pre-retinal haemorrhage, or fibrous proliferations on the disc or elsewhere), macular oedema (retinal thickening within one disc diameter of the macular centre) or blindness in either eye (corrected visual acuity 6/60 or worse, persisting for three months or more) not known to be due to non-diabetic causes or
   * A first diagnosis of type 2 diabetes made 10 or more years prior to entry or
   * Another major risk factor for vascular disease defined as any one of: current daily cigarette smoking, total cholesterol greater than 6.0 mmol/l (with or without cholesterol lowering treatment), HDL cholesterol \<1.0 mmol/l, microalbuminuria (albumin:creatinine ratio 30-300ug/mg) or
   * Age 65 years or over

Exclusion Criteria:

1. A definite contraindication to treatment with an ACE inhibitor or a thiazide-like diuretic
2. A specific indication for treatment with an ACE inhibitor other than perindopril 2-4 mg daily (see also section 5.2.3) or a thiazide-like diuretic
3. A definite and specific indication for treatment with gliclazide or a haemoglobin A1c control target of 6.5% or less
4. A definite contra-indication to treatment with gliclazide or a haemoglobin A1c control target of 6.5% or less
5. A definite indication for long-term full-dose or bed-time insulin therapy
6. Participation in a trial within the month prior to the Registration Visit or current participation in another trial

Other potential reasons for ineligibility include:

* High probability of non-adherence to study treatment or follow-up
* Current clinical instability (e.g. a major cerebral or coronary event or sight-threatening retinopathy or macular oedema within the previous few weeks)
* Life threatening non-vascular disease other than diabetes and its complications
* Moderate or severe dementia
* Major disability that is likely to prevent regular attendance at study clinics

Final decisions about eligibility were made at the discretion of the study investigator and the potential study participant, in the light of any requirements or guidance from local ethics committees and other regulatory bodies.
C: Inclusion Criteria:

* Subjects diagnosed with type 2 diabetes and treated with oral anti-diabetic drugs (OADs) for at least 3 months
* HbA1c: 7.0-11.0 % (both incl.) in subjects on OAD monotherapy. 7.0-10.0 % (both incl.) in subjects on OAD combination therapy
* Body Mass Index (BMI) less than or equal 40 kg/m2

Exclusion Criteria:

* Subjects treated with insulin within the last three months
* Subjects with any serious medical condition
* Females of child bearing potential who are pregnant, breast-feeding or have the intention of becoming pregnant or not using adequate contraceptive methods
* Subjects using any drug (except for OADs), which in the Investigator's opinion could interfere with the glucose level (e.g. systemic corticosteroids)
D: Inclusion Criteria:

* Type 2 diabetes
* Stable treatment with Oral Anti-Diabetic Drugs (metformin, sulphonylurea or a combination of both) for at least 3 months at the discretion of the Investigator
* HbA1C equal to or greater than 7.0% and equal to or lower than 11.0%
* Body Mass Index (BMI) equal to or lower than 45.0 kg/m2

Exclusion Criteria:

* Previous treatment with insulin
* Treatment with any anti-diabetic drug other than metformin and sulphonylurea
* Any previous exposure to exenatide or liraglutide
* Impaired liver or/and renal function
* History of any significant cardiac events
* Known retinopathy or maculopathy requiring acute treatment
* Recurrent major hypoglycaemia or hypoglycaemic unawareness
