Table 1 Key inclusion criteria CAROLINA®

From: Rationale and design of the CAROLINA® - cognition substudy: a randomised controlled trial on cognitive outcomes of linagliptin versus glimepiride in patients with type 2 diabetes mellitus

Insufficient glycaemic control defined as one of the criteria (A or B)

AND

Elevated risk of cardiovascular events defined as any (one or more) of the criteria (A, B, C or D)

(A) HbA1c 6.5 - 8.5% (48–69 mmol/mol) while patient is treatment naïve or treated with:

 (I) Metformin monotherapy

 (II) α-Glucosidase inhibitor monotherapy (e.g. acarbose, voglibose)

 (III) Metformin plus α-glucosidase inhibitor (e.g. acarbose, voglibose)

(B) HbA1c 6.5 - 7.5% (48–58 mmol/mol) while patient is treated with:

 (I) SU monotherapy

 (II) Glinide monotherapy (e.g. repaglinide, nateglinide)

 (III) Metformin plus SU (for a maximum of 5 years)

 (IV) Metformin plus glinide (for a maximum of 5 years)

 (V) α-Glucosidase inhibitor plus SU (for a maximum of 5 years)

 (VI) α-Glucosidase inhibitor plus glinide (for a maximum of 5 years)

(A) Previous vascular disease:

(I) MI (>6 weeks prior to informed consent IC)

(II) Documented coronary artery disease (50% luminal diameter narrowing of left main coronary artery or in at least two major coronary arteries in angiogram)

(III) Percutaneous coronary intervention (>6 weeks prior to IC)

(IV) Coronary artery bypass grafting (>4 years prior to IC) or with recurrent angina following surgery

(V) Ischaemic or haemorrhagic stroke (>3 months prior to IC)

(VI) Peripheral occlusive arterial disease

(B) Evidence of vascular-related end-organ damage:

(I) Moderately impaired renal function (as defined by MDRD formula) with eGFR 30–59 ml/min/1.73 m2

(II) Random spot urinary albumin:creatinine ratio 30 μg/mg in two of three unrelated specimens in the previous 12 months.

(III) Proliferative retinopathy defined as retinal neovascularization or previous retinal laser coagulation therapy

(C) Age ≥ 70 years

(D) At least two of the following cardiovascular risk factors:

(I) T2DM duration >10 years

(II) Systolic BP > 140 mmHg (or on at least 1 BP-lowering treatment) <6 months prior to IC

(III) Current daily cigarette smoking

(IV) LDL-cholesterol 135 mg/dL (3.5 mmol/L) (or specific current treatment for this lipid abnormality) <6 months prior to IC
