2 Aims of the FIELD eye study A.“FIELD sub-analysis”; To analyse the reasons for reduction in laser therapy in FIELD B.“Ophthalmology sub-study”; To assess the effect of fenofibrate on the progression of diabetic retinopathy in a sub-group of FIELD patients FIELD Study Investigators. The Lancet. 2007

3 First course of laser therapy FIELD Study Investigators. The Lancet % Rapid benefits of fenofibrate were seen from eight months onward and increased throughout the study period These benefits were additive to tight blood pressure and glycaemic control

4 The risk reduction was essentially due to macular oedema A significant 31% reduction due to macular oedema related laser treatment A significant 30% (p=0.015) reduction for proliferative retinopathy FIELD Study Investigators. The Lancet. 2007

5 Multiple courses of laser therapy EventPlaceboFenofibrateHazard Ratio 95% CIP-value 1 laser only , , % reduction 2-12 laser courses 11770

6 Fenofibrate benefits patients from cumulative use of laser therapy The relative reduction seen with fenofibrate was significant in patients without prior retinopathy (49%, p=0.0002) FIELD Study Investigators. The Lancet Fenofibrate Favours fenofibrate

9 Sub-study main endpoint Development of retinopathy defined as at least a 2-step increase in the ETDRS grade after 2 or more years of follow-up for all patients. Also sub classified as:  Primary prevention: 2-step progression to retinopathy in those with a baseline grade of 15 or less.  Secondary prevention: 2-step progression of existing retinopathy in those with a baseline grade of 20 or greater

10 Sub-study composite endpoint Exploratory combined outcome characterizing significant retinal pathology, composed of:  2-step progression of retinopathy grade  development of macular oedema  or laser therapy

14 Clinical Application - 5 years treatment with fenofibrate With pre-existing retinopathy Avoid first laser: NNT = fewer multiple laser events per 100 Rx Without known prior eye disease Avoid first laser: NNT = fewer multiple laser events per 100 Rx

15 Conclusions In all subjects with diabetes, the use of fenofibrate could be considered for both its macro- and microvascular benefits Even for subjects on statin therapy at target LDL-C, fenofibrate could be considered as add- on therapy to further attenuate residual diabetes-mediated risk and its microvascular complications (ACCORD study will provide further evidence for combination statin-fenofibrate therapy)

19 Results

20 Conclusions Silent MI is common in individuals with type 2 diabetes - almost 40% of all MI There were 16% fewer first silent MI events on fenofibrate (p = 0.154) Fenofibrate significantly reduced the occurrence all MI events by 20% (95% CI 6- 31%, p=0.006) After silent MI, fenofibrate reduced the risk of further clinical CVD events (p=0.008)
