    Author: Herregods MC, Daubresse JC, Michel G, Lamotte M, Vissers E, Vandenhoven G, Discovery Belux.
    Journal: Acta Cardiol; 2008 Aug; 63(4):493-9. PubMed ID: 18795588.
    Abstract:
    METHODS: Discovery Belux is an open-label, multicentre, randomised, phase IIIb, parallel group study comparing the efficacy of rosuvastatin (RSV) and atorvastatin (ATV) on changes in lipid levels and the achievement of European Atherosclerosis Society (EAS) lipid goals. Patients (> or = 18 years) with primary hypercholesterolaemia, with a low-density lipoprotein (LDL-C) level > 120 mg/dl (on treatment) or > 135 mg/dl (naive subjects), and with a statin indication, were randomised to receive RSV 10 mg/day or ATV 10 mg/day for 12 weeks. Patients not at goal after 12 weeks and receiving ATV 10 were further switched to RSV 10 mg for another 12 weeks. Patients not at goal with RSV 10 mg were further titrated to RSV 20 mg. RESULTS: 938 patients were randomised to the two treatment groups. After 12 weeks of treatment, a significantly greater percentage of patients receiving RSV 10 compared with ATV 10 achieved EAS LDL-C target goal (< 115 mg/dl) (85% vs. 67%). LDL-C was reduced by 47% and total cholesterol (TC) by 33% with RSV 10.This was 38% and 27% for ATV 10, respectively. After 24 weeks, an additional 57% of patients initially taking RSV 10 and uncontrolled, reached the target with RSV 20. In the patient group, initially taking ATV 10 and uncontrolled, 65% reached the target with RSV 10 after 24 weeks. Both treatments were well tolerated with a similar incidence of adverse events. In addition, a health economic analysis was performed. As RSV 10 is available at a lower cost in Belgium and as it is more effective, compared to ATV 10, it appeared to be the option of choice from a cost-effectiveness perspective. CONCLUSIONS: Rosuvastatin 10 mg treatment is significantly more effective than atorvastatin 10 mg at achieving European LDL-C goals, at lowering LDL-C and TC. These results were obtained with a similar safety profile. From a cost-effectiveness perspective RSV 10 is the preferred therapeutic option in comparison with ATV 10. Uptitration of uncontrolled patients to RSV 20 mg and switch from ATV 10 to RSV 10 allowed significantly more patients to reach the LDL-C and TC target goal.
