This is a multi-center, double blind, prospective, longitudinal, randomized, 12-week study with a 52-week open-label follow-up to evaluate the safety and efficacy of daily administration of Pravastatin 40 mg or Fenofibrate 160 mg or Pravafen (the combination of both Pravastatin and Fenofibrate 40/160 mg) in the treatment of combined hyperlipidemia. There will be an open-label, 8-week, Selection Phase prior to randomization in which all patients will be stabilized on Pravastatin 40 mg/day. Following the Selection Phase, and if the patients meet all inclusion/exclusion criteria, they will be randomized to a three arm, double blind, 12-week Efficacy Phase during which they would receive either Pravastatin 40 mg or Fenofibrate 160 mg or Pravafen (the combination of Pravastatin and Fenofibrate 40/160 mg). The 12-week Efficacy Phase will be followed by an open-label, 52-week, Safety Phase in which all patients will receive Pravafen. After the 8-week Selection Phase, patients that still meet the inclusion/exclusion criteria will be randomized on a 1:1:2 ratio to Pravastatin 40 mg or Fenofibrate 160 mg or Pravafen (the combination of both Pravastatin and Fenofibrate 40/160 mg) for 12 weeks. After the completion of the 12-week double-blind phase of the study, all patients that haven't had changes in their well being, will be allowed to roll-over into the 52-week, open-label, follow-up portion of the study. During the 52 week, open label, Safety Phase of the study, all patients will receive Pravafen (the combination of Pravastatin and Fenofibrate 40/160 mg). Patients will be evaluated at baseline and every three weeks thereafter throughout the initial 12-week Efficacy Phase of the study. Patients that roll-over into the 52-week, open-label, follow-up Safety Phase will be evaluated at 12, 24, 36 and 52 weeks. Participation in the study can be up to 72 weeks.
Despite undeniable progress in the reduction of morbidity and mortality of coronary heart disease (CHD) prevention is a mainstay for medical intervention. The importance of elevated serum cholesterol for the formation and progress of CHD can be regarded as proved after the results of the major intervention studies became available. These studies have provided key evidence for a positive correlation of lipid lowering and decreased mortality. Other studies in patients with established CHD have shown that stabilization and regression of atherosclerotic lesions is possible with lowering of cholesterol using a variety of agents. Different studies have also investigated the long-term effects of lipid lowering strategies on atherosclerosis by means of coronary angiography and have demonstrated that lipid reduction reduces progression of atherosclerosis and can promote atherosclerosis regression. Thus, it has been demonstrated that cholesterol lowering therapy reduces the risk of CHD and diminishes cardiovascular morbidity and mortality. Policosanol is a drug that presumably possesses both hypocholesterolemic and antiplatelet effects. Furthermore there are hints to even more positive effects that influence the development of atherosclerosis, i.e. inhibition of LDL peroxidation and smooth muscle cell proliferation. Previous studies showed efficacy in dose ranges of mostly 5 to 20 mg Policosanol per day. As nearly all previous studies have been performed in Latin America it cannot be excluded that either ethnic or nutritional factors contribute to the dose found to be optimal in this region. This circumstance as well as the requirement to meet the ICH Guideline “Ethnic Factors in the Acceptability of Foreign Clinical Data” make further studies, i.e. a dose-finding clinical trial, an efficacy clinical trial in European patients and a long-term tolerability clinical trial in Caucasian patients necessary. It is known from more than 60 clinical studies performed so far that Policosanol has an excellent safety profile. A placebo-controlled design was considered appropriate as patients with two or more risk factors for the development of cardiovascular events and a LDL of greater than 190 mg/dl were excluded; the chance of getting an active lipid-lowering agent during the treatment phase was 80 %.
