This is a randomized, double-blind, placebo-controlled, two-to three center study. The study will consist of 2 treatment groups (Betahistine 48 mg/day or matching placebo). Approximately 30 subjects (15 per treatment group) will be randomized into this 6-week study. A single blinded placebo treated period of up to 14 days will be used to determine subjects suitability for inclusion in the trial. In order that a patient will be defined as valid for inclusion in the study, patients should be able to present consistent LDL-C values, taken prior to randomization (at screening visit 1 and screening visit 2), without deviation of more than 12% of each value from their mean. Within one week from the second screening visit, subjects who meet all inclusion criteria and none of the exclusion criteria will be randomly assigned to 1 of the following treatment groups: - Betahistine 24 mg BID (48 mg/day total), or - Matching placebo BID. Double-blind treatment will continue for 4 weeks. Study medication (betahistine and/or matching placebo) will be administered BID (before lunch and before dinner). During the study, subjects will undergo dietary assessment. The primary efficacy parameter is change in LDL-C from baseline (randomization) to Week 4 and the percentage of patients that reduce their LDL-C by 10% or more.
Elevated levels of D-dimer, a marker of procoagulant state, have been identified as a marker of an increased risk of recurrent VTE. Statins have proven antithrombotic properties, as suggested by the reduction of several prothrombotic markers, including D-dimer, in patients at high risk of arterial thrombosis. Such antithrombotic properties could also be observed in patients at high risk of venous thrombosis. Aim of the study is to assess the effect of statins on D-dimer levels in patients with previous VTE after oral anticoagulant treatment withdrawal.
The purpose of this study is to compare the effectiveness and safety of rosuvastatin 5mg in lowering blood cholesterol, compared to one other medicine, atorvastatin 10mg in Asian patients in the UK.
This is a 105-week clinical study in patients with heterozygous familial hypercholesterolemia on intensive Low Density Lipoprotein-cholesterol (LDL-C) lowering therapy intended to assess the affects of MK0524A on carotid intima media thickening using ultrasound compared to patients taking placebo. There will be 12 scheduled clinic visits involving review of medical history, physical exam, vital signs, laboratory testing, ultrasound imaging, and electrocardiograms.
Laparoscopic Adjustable Gastric Banding (LAGB) is a gold standard in the surgical treatment of morbid obesity. We hypothesize that the addition of truncal vagotomy (cutting of nerves to the stomach) will produce greater weight loss and better reduction of co-morbidities (diseases caused by or aggravated by morbid obesity) than LAGB alone. 25 patients will be enrolled and outcomes compared to LAGB historical controls over a post-operative period of 24 months.
To assess the cholesterol changing effects of MK0859 in patients with primary hypercholesterolemia or mixed dyslipidemia.
The natural thyroid hormones, thyroxine (T4) and triiodothyronine (T3), are known to have a cholesterol-lowering effect. Their pharmacologic use for this purpose is limited, however, by their actions on other organs, including the heart, bone, and brain, where there can be side effects of excessive thyroid hormone action. 3,5-diiodothyropropionic acid (DITPA) is a thyroid hormone analog with relative selectivity for a form of the thyroid hormone receptor expressed in the liver, where it regulates several aspects of lipid metabolism, including the clearance of low-density lipoprotein (LDL) cholesterol. This study is designed to determine whether DITPA is safe and effective in achieving LDL cholesterol levels that are consistent with the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) guidelines in patients who have not achieved those levels on conventional therapy, due to drug-resistant disease, drug intolerance, or both. This is a single-center, randomized, double-blind, placebo-controlled study. Following a 4-week Pre-Randomization Phase with dietary counseling and a 2-week placebo run-in, eligible patients will be randomized (1:1:1) to receive DITPA (90 mg/day, 180 mg/day), or placebo for a total treatment duration of 12 weeks. Sixty (60) patients will be randomized to 1 of 3 treatment groups in a 1:1:1 ratio (i.e., 20 patients per treatment group): - DITPA at 90 mg/day (45 mg twice a day [BID] taken orally) - DITPA at 180 mg/day (90 mg BID taken orally) - Placebo (BID taken orally) Those patients randomized to receive DITPA at 90 mg/day will receive 45 mg/day for the first 2 weeks, followed by 90 mg/day for 10 weeks. Those patients randomized to receive DITPA at 180 mg/day will receive 45 mg/day for the first 2 weeks, followed by 90 mg/day for the next 2 weeks, and then 180 mg/day for 8 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 %.
The Torcetrapib project was terminated on December 2, 2006 due to safety findings. Cholesterol levels will be measured over six weeks in subjects being treated with two different kinds of cholesterol medications to see how the different treatments compare to one another.
