Scientific title	The effect of the peroxisome proliferator-activated receptor alpha agonist fenofibrate on insulin sensitivity compared to atorvastatin in type 2 diabetes mellitus: A randomised, double-blind controlled trial
Study objectives	The peroxisome proliferator-activated receptor alpha agonist fenofibrate may increase insulin sensitivity compared to atorvastatin in type 2 diabetes mellitus.
Ethics approval(s)	Local Research and Ethics Committee of the Queen's University of Belfast. Date of approval: 29/10/2003 (ref: 175/03)
Health condition(s) or problem(s) studied	Type 2 diabetes mellitus, insulin resistance
Intervention	This is a randomised, cross-over trial. Treatment 1: Micronised fenofibrate (oral) 267 mg once daily Treatment 2: Atorvastatin (oral) 10 mg once daily Intervention schedule: Previous lipid-lowering therapy was withdrawn for 4 weeks prior to assessment for entry eligibility criteria. Subjects then commenced a 4-week placebo run-in after which baseline assessments were carried out. The participants were then randomised to either fenofibrate or atorvastatin in a double-blinded manner and continued for 12 weeks, after which end-point assessments were carried out. A 4-week placebo-controlled washout period followed, and then subjects proceeded to 12 weeks therapy with the alternative blinded therapy (atorvastatin or fenofibrate). End-points were again assessed after this treatment period. The full period of follow-up of each individual volunteer was 36 weeks, and is broken down as follows: 1. 4 week washout period from previous therapy 2. 4 week placebo run-in period 3. 12 week treatment period 1 4. 4 week placebo wash-out period 5. 12 week treatment period 2
Intervention type	Drug
Pharmaceutical study type(s)
Phase	Not Specified
Drug / device / biological / vaccine name(s)	Fenofibrate, atorvastatin
Primary outcome measure	Glucose infusion rate required to maintain isoglycaemia in the last 30 minutes of a 2-hour insulin infusion at a rate of 2 mU/kg/minute. This was assessed within three days of the end of each treatment period.
Secondary outcome measures	The following were assessed within three days of the end of each treatment period: 1. Isotopically-determined total body glucose disposal rate and suppression of endogenous glucose production in the last 30 minutes of a 2-hour insulin infusion at a rate of 2 mU/kg/minute 2. Serum total, low-density and high density cholesterol and fasting total triglyceride
