Crossover of Higher Dose Statins in Patients With Low High-density Lipoproteins Cholesterol (HDLc)

The subject will be asked to come in for all study visits in a fasting state (only water for past 12 hours). Both blood pressure and pulse will be checked at the screening visit as well as all study visits. The baseline (screening) visit will include the consenting process and completion of the first section of the Data Collection Sheet to further screen for appropriate inclusion and exclusion criteria. Subjects who are on a statin will need to have an 8-week wash out period prior to beginning the trial. The subject and their primary provider must agree to the washout. At the screening visit for subjects not taking a statin drug, 13 ml of blood will be drawn. The blood will be processed by the OCTRI Core Laboratory staff. All of the lipid parameters (complete lipid profile, apoB, apoA1, hs-CRP) will be tested at the OHSU lipid core lab. Some of the blood collected will be sent to the OHSU core lab for testing of ALT as well as for obtaining the long-term storage sample. Blood samples will be frozen and stored on the 14th floor of the CHH building in the laboratory of the Oregon State University School of Pharmacy. Samples will be batched for processing (see sample processing below). The lipid profile and ALT from the screening visit will be processed within approximately one week. If necessary laboratory parameters meet inclusion and exclusion criteria, the subject will be scheduled for the first study visit. Encapsulated placebo will be given to the subject to take in between the screening and first study visit. At the screening visit for subjects taking a statin drug, the study will be described and consent to enroll will be obtained but no bloodwork will be performed. Subjects will be given an encapsulated placebo to take for an 8 week washout period. At the second screening visit, blood will be drawn to ascertain baseline laboratory values as described above for subjects not on a statin drug. The subject will then be scheduled for their first study visit 2 weeks later. The other laboratory parameters (hs-CRP, apoA1 and apoB) and all future bloodwork which is not necessary for the ongoing conduct of the trial may be batched and processed periodically. The ALT from the second study visit (after first course of study medication) will be processed prior to the third study visit to confirm that ALT remains less than 3 times ULR. If ALT is elevated (\>105 IU/L) at the second study visit, the subject will be discontinued from the study and the subjects primary physician notified. Additionally, if the subject complains of myopathy which is felt to be consistent with possible drug-induced myositis, a creatine phospho-kinase (CPK) test will be ordered. Consistent with the product package insert (PI) for both atorvastatin and simvastatin, therapy will be stopped and the subject discontinued from the study if CPK is greater than 10X the ULR. At the first study visit, the subject will be randomized by the OHSU Research Pharmacy to receive either 6 weeks of 80mg atorvastatin or 6 weeks of 80mg of simvastatin. The subject will be scheduled for follow-up 6 weeks from the trial entry date and asked to bring the investigational drug vial back at the next visit. The subjects will also be given a diary to record their daily dose of medication taken. A urine pregnancy test will be done at the first and third study visit in all women who are not post-menopausal as defined as at least 6 months without menstruation over the age of 50. Women who do not meet the post-menopausal criteria, are sexually active and not on any form of birth control will be counseled to begin and remain on birth control for the duration of the trial. Inability or unwillingness to comply with chosen birth control measures will result in exclusion from the trial. Women of child bearing potential not on birth control at the time of the screening visit who are willing to begin birth control will be scheduled for their first study visit not sooner than 6 weeks after their screening visit to allow time for implementation of chosen birth control. Subjects who are on hormone replacement therapy (HRT) will be allowed to enroll provided that their regimen is stable and not expected to change during the study period. Subjects will be informed that if their regimen does change during the study, they will need to be removed from the study. At the second visit, the appropriate section of the Data Collection Sheet will be completed, a pill count of remaining drug doses will be done and 13 ml of blood will be drawn and processed as previously outlined. The subject will then be scheduled for follow-up in 6 weeks and leave without any study medicine. At the third visit, the appropriate section of the Data Collection Sheet will be completed and 13 ml of blood will be drawn and processed as previously outlined. The subject will be given a 6 week supply of the second medication (as previously determined by first randomization scheme) and scheduled for follow-up in 6 weeks. At the fourth and final visit, the appropriate section of the data collection sheet will be completed and 13 ml of blood will be drawn and processed as previously outlined. In between study visits, the study staff will contact subjects by phone to remind them of their next appointment and ask about any adverse effects or other problems that the subject may be experiencing. In the event that the phone number of record becomes inactive, a letter will be sent to the address of record.
