FIELD trial
Effects of long-term fenofibrate therapy on cardiovascular events in 9795 people with type 2 diabetes mellitus (the FIELD study): randomised controlled trial.
The bottom line
In patients with type 2 diabetes not on statins, fenofibrate did not significantly reduce coronary events but did reduce total cardiovascular events, driven by fewer nonfatal heart attacks and revascularizations, with a small increase in pancreatitis and pulmonary embolism.

- Who took part
- 9795 participants aged 50-75 years, with type 2 diabetes mellitus, not taking statin therapy at study entry; 2131 with previous cardiovascular disease and 7664 without; total-cholesterol 3.0-6.5 mmol/L and total-cholesterol/HDL-cholesterol ratio of 4.0 or more or plasma triglyceride of 1.0-5.0 mmol/L

- Main question
- Coronary events (coronary heart disease death or non-fatal myocardial infarction)
Main result
5.9% (n=288) of patients on placebo and 5.2% (n=256) of those on fenofibrate had a coronary event (relative reduction of 11%; hazard ratio [HR] 0.89, 95% CI 0.75-1.05; p=0.16)

Other results
Total cardiovascular disease events were significantly reduced from 13.9% to 12.5% (0.89, 0.80-0.99; p=0.035), including a 21% reduction in coronary revascularisation (0.79, 0.68-0.93; p=0.003); non-fatal MI reduced 24% (0.76, 0.62-0.94; p=0.010); CHD mortality non-significantly increased (1.19, 0.90-1.57; p=0.22); total mortality 6.6% placebo vs 7.3% fenofibrate (p=0.18)
Safety
Fenofibrate was associated with less albuminuria progression (p=0.002), and less retinopathy needing laser treatment (5.2% vs 3.6%, p=0.0003). There was a slight increase in pancreatitis (0.5% vs 0.8%, p=0.031) and pulmonary embolism (0.7% vs 1.1%, p=0.022), but no other significant adverse effects.
