Detailed Description
Background:
Blacks have twice the risk of stroke compared to Whites and a recent analysis found that stroke incidence was decreasing in Whites but not Blacks. Identifying new avenues for stroke prevention is important in African Americans.
The Stroke Prevention through Aggressive Reduction of Cholesterol Levels (SPARCL) trial showed that treatment with atorvastatin 80 mg/d reduced the frequency of stroke by 16%. In the SPARCL trial, the mean low density lipoprotein-cholesterol (LDL-C in the treatment group was 73 mg/dl. On the basis of the SPARCL trial, the American Stroke Association now recommends statins with "intensive lipid lowering effects" for secondary prevention in the 2008 guideline update. Achieving target levels is most important for secondary prevention of stroke, when patients have an annual risk of stroke recurrence of 3-15% per year. Rosuvastatin is well suited for these secondary prevention goals due to its potent lipid-lowering effects.
Objectives
The objectives of this study are to establish the following:
- That a dose escalation regimen of rosuvastatin 20-40 mg will achieve 70% success in reaching the LDL-C target of <100 mg/dl
- That a dose escalation regimen of rosuvastatin 20-40 mg will achieve 50% success in reaching the LDL-C target of <70 mg/dl for individuals at highest risk
Design
60 patients will be identified from the inpatient and outpatient settings from two medical centers. African American patients with a diagnosis of ischemic stroke or transient ischemic attack (TIA) within the previous 12 months will be identified.
Both patients already on other statins and statin naïve patients will be recruited. For patients on other statins, a washout period will not be required due to ethical reasons. After providing informed consent, baseline lipid values will be obtained. Study subjects will be initiated on a starting dose of rosuvastatin of 20 mg. Subjects will be followed every six weeks for a 3 month period. A lipid profile and LFT's will be obtained at 6 weeks and 3 months. Patients not at the intensive LDL-C target of <70 mg/dl will be increased to 40 mg, if necessary.
The final 3 month lipid profile will be used to determine achievement of the targets.
Treatments
Rosuvastatin 20 mg will be the starting dose. As described above, patients may be titrated to 40 mg if the 6 week LDL cholesterol is >70 mg/dl.
Safety monitoring Adverse Event An Adverse Event (AE) is the development of an undesirable medical condition or the deterioration of a pre-existing medical condition following or during exposure to a pharmaceutical product, whether or not considered causally related to the product. An undesirable medical condition can be symptoms (eg, nausea, chest pain), signs (eg, tachycardia, enlarged liver) or the abnormal results of an investigation (eg, laboratory findings, ECG). In clinical studies, an AE can include an undesirable medical condition occurring at any time, including run-in or washout periods, even if no study treatment has been administered.
Any detrimental change in a patient's condition subsequent to them entering the study and during the follow-up period should be considered an AE. When there is a deterioration in the condition for which the study treatment is being used, there may be uncertainty as to whether this is lack of efficacy or an AE. In such cases, unless the reporting physician considers that study treatment contributed to the deterioration or local regulations state to the contrary, the deterioration should be considered a lack of efficacy. Signs and symptoms of disease progression are therefore not considered AEs.
