5 Rosuvastatin versus Atorvastatin Změny v HDL-C The STELLAR Study
Change in HDL-C from baseline (%) 12 Rosuvastatin Atorvastatin * 10 ns n=473 8 6 4 2 n=634 Data from STELLAR demonstrates that rosuvastatin produces a significant HDL-C raising effect which is maintained across the dose range, in contrast to atorvastatin where the HDL-C raising effect diminishes with increasing dose1. In practice, this means that increasing the atorvastatin dose to achieve the same level of LDL-C reduction as rosuvastatin will result in less favourable effect on HDL-C. rosuvastatin 10 mg raised HDL-C statistically significantly more than pravastatin 10 mg (p<0.002). rosuvastatin 20 mg raised HDL-C statistically significantly more than atorvastatin 20, 40 and 80 mg, simvastatin 40 mg, and pravastatin 20, 40 mg (p<0.002). rosuvastatin 40 mg raised HDL-C statistically significantly more than atorvastatin 40 and 80 mg, simvastatin 40 mg, and pravastatin 40 mg (p<0.002). Mean baseline HDL-C for rosuvastatin group: 51 mg/dL. Remember that the NCEP Expert Panel have estimated, based on data from epidemiology studies as well as intervention studies, that every 1% increase in HDL-C equates to a 3% reduction in CHD risk2.

The superiority of rosuvastatin 10 mg over atorvastatin 10 mg was confirmed in MERCURY I. In this study, significantly more patients achieved their NCEP ATP III LDL-C goal when treated with rosuvastatin 10 mg than with atorvastatin 20 mg (80% vs. 74%, p<0.01).2 In patients with documented atherosclerosis or Type 2 diabetes who have a more challenging NCEP ATP III LDL-C goal of <100 mg/dL (<2.6 mmol/L), the superiority of rosuvastatin 10 mg over atorvastatin 10 mg was particularly marked (60% vs. 19%, p<0.001).1 References Shepherd J, Hunninghake DB, Barter B et al.

Semiannual Reporting Rates for All Reports of Rhabdomyolysis US Cases* Worldwide Cases‡ Rosuvastatin Cerivastatin 120 80 100 120 60 40 20 -20 Fluvastatin 100 Atorvastatin Lovastatin 80 Pravastatin Reporting Rate Per 1,000,000 US Prescriptions ** Simvastatin 60 Reporting Rate Per 1,000,000 rosuvastatin prescriptions worldwide‡ Ezetimibe 40 Rosuvastatin AZ global database 20 UPDATED VERSION 17 MARCH 2005 Key Point: Postmarketing surveillance clearly demonstrates that the rate of rhabdomyolysis for rosuvastatin is in line with to that for other currently marketed statins. Rhabdomyolysis is an expected adverse event that occurs with all marketed statins,1 and rare cases with acute renal failure secondary to myoglobinuria have been reported with rosuvastatin and other drugs in this class.2 To address concerns of rhabdomyolysis with rosuvastatin, a comparison of postmarketing data for rosuvastatin, other statins and ezetimibe was performed. Data for comparator statins and ezetimibe were obtained from the Federal Drug Administration (FDA) Adverse Event Reporting System (AERS), available to the public through the Freedom of Information Act (FOI); these data are presented on the left hand side of this chart, reported as semiannual rates from 1999 up to August US prescription data obtained from the IMS were used to calculate the reporting rate of rhabdomyolysis per 1,000,000 prescriptions. The addition of rosuvastatin data to the FDA database has only recently started and currently is too limited to allow a semi-annual rate trend to be plotted. The left hand side of the above chart does not therefore include rosuvastatin data. However, data relating to worldwide spontaneous reports up to and including February 2005 is held within the internal global safety database of AstraZeneca and for completeness, the right hand side of this chart presents data from this database as a semi-annual reporting rate (calculated by dividing the worldwide spontaneous reports of rhabdomyolysis by the number of worldwide prescriptions for rosuvastatin). This worldwide data, which covers the time frame from March 2003 to the end of February 2005, therefore represents the most up to date and comprehensive information for rosuvastatin available. As shown here, the worldwide semiannual reporting rate for rosuvastatin was in line with the reporting rates of other statins. This is particularly noteworthy because new drugs are expected to have higher reporting rates of adverse events in their first year of launch.3 As clearly depicted on the slide, the reporting rate of rhabdomyolysis for cerivastatin was much higher compared with the other currently marketed statins. The increase in reporting rate of rhabdomyolysis with cerivastatin over the time period shown may be due in part to the US launch of higher doses - cerivastatin 0.4 mg in May 1999 and subsequently 0.8 mg in July The increase in reporting rate of rhabdomyolysis was clearly seen within 1 year of the launch of these higher doses. It is important to note that this type of analysis has the following limitations: The FDA AERS safety reports are spontaneous, not fully investigated, and do not imply a causal relationship; spontaneous reporting rates are likely to be lower than the actual incidence of adverse events due to underreporting; the spontaneous reporting rates of rhabdomyolysis for rosuvastatin, other comparator statins and ezetimibe do not represent head-to-head comparative studies and must be interpreted with caution; and the use of reporting rates as proxy measures of risk also has the limitation of secular trends.4 References 1.

Data for comparator statins and ezetimibe were obtained from the Federal Drug Administration (FDA) Adverse Event Reporting System (AERS), available to the public through the Freedom of Information Act (FOI); these data are presented on the left hand side of this chart, reported as semiannual rates from 1999 up to August US prescription data obtained from the IMS were used to calculate the reporting rate of fatal rhabdomyolysis per 1,000,000 prescriptions. The addition of rosuvastatin data to the FDA database has only recently started and currently is too limited to allow a semi-annual rate trend to be plotted. The left hand side of the above chart does not therefore include rosuvastatin data.

This worldwide data, which covers the time frame from March 2003 to the end of February 2005, therefore represents the most up to date and comprehensive information for rosuvastatin available. The expected rate of rhabdomyolysis related fatalities for the statin class is 1/1,000,000. Thus, the actual rate observed with rosuvastatin in this analysis is below that anticipated. This is particularly noteworthy because new drugs are expected to have higher reporting rates of adverse events in their first year of launch.1 The increase in reporting rate of fatal rhabdomyolysis with cerivastatin over the time period shown may be due in part to the US launch of higher doses - cerivastatin 0.4 mg in May 1999 and subsequently 0.8 mg in July The increase in reporting rate of fatal rhabdomyolysis was clearly seen within 1 year of the launch of these higher doses. It may be noted that the FDA data appears to show a rosuvastatin related case of fatal rhabdomyolysis in the period 09/03 to 02/04. Although initially reported as a case of fatal rhabdomyolysis (and hence listed as a report within the FDA database) subsequent post-mortem confirmed that the cause of death was myocardial infarction unrelated to the use of rosuvastatin. It is important to note that this type of analysis has the following limitations: The FDA AERS safety reports are spontaneous, not fully investigated, and do not imply a causal relationship; spontaneous reporting rates are likely to be lower than the actual incidence of adverse events due to underreporting; the spontaneous reporting rates of rhabdomyolysis for rosuvastatin, other comparator statins and ezetimibe do not represent head-to-head comparative studies and must be interpreted with caution; and the use of reporting rates as proxy measures of risk also has the limitation of secular trends.2 References 1.

Two of these studies, COMETS and LUNAR also assess the effects of Rosuvastatine on inflammatory markers. Studies designed to investigate the effect of Rosuvastatine on ‘atherosclerosis’ are METEOR, ASTEROID and ORION. Studies designed to investigate the effect of Rosuvastatine on ‘cardiovascular morbidity and mortality’ are AURORA, CORONA and JUPITER. The GALAXY Programme currently includes 16 clinical studies. However, as the GALAXY Programme is constantly evolving new studies will be included as the statin environment changes, research needs dictate and the clinical development of Rosuvastatine continues.

Outcome of Rosuvastatin Treatment on Carotid Artery Atheroma: a Magnetic Resonance Imaging ObservatioN Měření změn velikosti aterosklerotického plátu na karotidě pomocí MR u asymptomatických pacientů s hypercholesterolémií léčených 5mg rosuvastatinu nebo 40 mg rosuvastatinu. Core slide The early detection of atherosclerosis allows more effective targeting of preventive intervention. Magnetic resonance imaging (MRI) is a non-invasive technique that permits the quantification of atherosclerotic lesion size and the identification of plaque characteristics (Zhao et al 2001). In a study of asymptomatic patients with hypercholesterolaemia, the vascular effects of statin treatment have been monitored using MRI (Corti et al 2001). After 12 months’ treatment, significant reductions in vessel wall thickness and vessel wall area were observed (Corti et al 2001). The primary objective is to measure the change in carotid atheroma volume as assessed by MRI in hypercholesterolaemic patients with asymptomatic carotid disease after 24 months’ treatment with rosuvastatin 5 mg or rosuvastatin 40 mg. The secondary objectives are to evaluate the effects of rosuvastatin on lesion composition, intima media thickness of the carotid arteries, and lipids, lipoprotein and markers of inflammation. Safety and tolerability will also be assessed. References Corti R et al.

Approximately 200 individuals from 2 centres in the US were screened and after an initial enrolment period, 39 patients were randomised to receive either rosuvastatin 5 mg or rosuvastatin 40 mg once daily for 24 months. The primary end point is change from baseline in carotid atheroma volume after 24 months. The secondary end points are: carotid wall composition (as assessed by index of lesion MRI signal), unilateral and bilateral measurements minimal carotid lumen cross-sectional area, unilateral and bilateral measurements carotid artery wall volume, unilateral measurement mean intima media thickness (IMT) of the carotid arteries by B-mode ultrasound cell infiltration, expression of markers of vascular inflammation (eg intercellular adhesion molecule-1 and CD-40 ligand) and possible rosuvastatin content in patients progressing to endarterectomy change (%) from baseline in CRP, IL-6 and homocysteine change (%) from baseline in TC, TG, LDL-C, HDL-C and lipoprotein particle size safety.
