Outline What have we learned with ADVANCE trial? Why the other Glycemic intensive control trials didn’t achieve the aims ? How to translate in clinical practice the results of ADVANCE Trial

Diabetic vascular complications: what is the A 1c target? Previous studies: DCCT (1993) and UKPDS (1998) showed that a tighter control of A1c helps to prevent diabetic complications But the intention of these trials was to target normal Blood Glucose and not A1c

What have we learned with ADVANCE trial? A 1c progressive and sustained reduction Gliclazide MR at the dose of 120 mg in 70% of patients ADVANCE collaborative group. N Engl J Med 2008; 358: Mean HbA 1c at final visit Mean HbA1c (%) Follow-up (Months) % 6.5% Δ 0.67% (95% CI 0.64 – 0.70); p< Standard Intensive (Gliclazide MR)

What have we learned with ADVANCE trial? Progressive and sustained blood glucose control (6.5% of A1c) Reduction of serious complications (-10% primary endpoint) Kidney protection (-21% nephropathy, regression to normoalbuminuria) Reduction of CV risk markers (-30% in albuminuria) Trend toward CV mortality reduction (-12%) Safe and weight neutral ADVANCE collaborative group. N Engl J Med 2008; 358:

What have we learned with ADVANCE trial? Efficient glycemic control whatever the patient profile Gliclazide MR always provides an efficient glycemic control ADVANCE Collaborative Group. IDF Annual Meeting, Canada, Montreal. Posters

Zoungas Diabetes Care 2009 Cardiovascular death is reduced by 24% (p=0.04) Renal disease is reduced by 33% (p=0.005) What have we learned with ADVANCE trial? Interaction data

Multifactorial treatments including routine blood pressure lowering and intensive glucose control are indicated for all patients with type 2 diabetes What have we learned with ADVANCE trial? Conclusions on Joint effects The effects of the 2 treatments were independent of one another for all clinical outcomes Where both treatments had a significant effect, these effects were fully additive Where only one treatment had a significant effect, the second treatment preserved that effect

Morbidity-mortality study: ACCORD (2008) Morbidity-mortality study in type 2 diabetic patient aiming at HbA 1c  6% Increase in total mortality (HR 1.22, p=0.04) Non significant reduction in the primary end point Significant increase in cardiovascular mortality Reasons for increased mortality ? too sharp decrease in HbA 1c ? too sharp decrease in HbA 1c ? hypoglycemic events ? hypoglycemic events ? adverse events related to the choice of drugs ? adverse events related to the choice of drugs ?
