Safety of rosuvastatin

The safety and tolerability of rosuvastatin were assessed (as of August 2003) using data from 12,400 patients who received 5 to 40 mg of rosuvastatin in a multinational phase II/III program, which represented 12,212 patient-years of continuous exposure to rosuvastatin. An integrated database was used to examine adverse events and laboratory data. In placebo-controlled trials, adverse events, irrespective of causality assessment, occurred in 57.4% of patients who received 5 to 40 mg of rosuvastatin (n = 744) and 56.8% of patients who received placebo (n = 382). In fixed-dose trials with comparator statins, 5 to 40 mg of rosuvastatin showed an adverse event profile similar to those for 10 to 80 mg of atorvastatin, 10 to 80 mg of simvastatin, and 10 to 40 mg of pravastatin. Clinically significant elevations in alanine aminotransferase (>3 times the upper limit of normal) and creatine kinase (>10 times the upper limit of normal) were uncommon (≤0.2%) in the groups that received rosuvastatin and comparator statins. Myopathy (creatine kinase >10 times the upper limit of normal with muscle symptoms) that was possibly related to treatment occurred in ≤0.03% of patients who took rosuvastatin at doses ≤40 mg. A positive finding of proteinuria with dipstick testing at rosuvastatin doses ≤40 mg was comparable to that seen with other statins, and the development of proteinuria was not predictive of acute or progressive renal disease. No deaths in the program were attributed to rosuvastatin, and no rhabdomyolysis occurred in patients who received 5 to 40 mg of rosuvastatin. Rosuvastatin was well tolerated by a broad range of patients who had dyslipidemia, and its safety profile was similar to those of the comparator statins investigated in this extensive clinical program.

Ethical considerations

The trials in the rosuvastatin clinical development program were designed and conducted in accordance with the Declaration of Helsinki (versions amended October 1996 and October 2000) and in compliance with the ethical principles of good clinical practice. Appropriate ethics committees or institutional review boards approved the research protocols; all patients (or their parents or guardians) gave their written, informed consent before initiation of any trial procedure.

Demographic and baseline characteristics

Demographic and baseline characteristics of the 12,400 patients who received 5 to 40 mg of rosuvastatin in the phase II/III program are listed in Table 1. This population included large numbers of patients ≥65 years old, women, and patients who had cardiovascular disease, diabetes mellitus, hypertension, and renal impairment. The 8 patients who were <18 years of age were included in a trial in patients with homozygous familial hypercholesterolemia. No major differences in demographic or

Discussion

The rosuvastatin phase II/III program was designed to study a patient population that had dyslipidemia and was representative of the patients who should receive statin therapy in clinical practice, particularly those patients characterized as “high risk” according to international cholesterol guidelines.12, 13 Altogether, 12,400 patients received 5 to 40 mg of rosuvastatin, representing >12,000 patient-years of continuous exposure in clinical trials. In this program, rosuvastatin was well
