The transcription factor PPAR- was influenced by diabetes Figure 2 ; , suggesting that atheromas from these patients might respond differently. Our cell culture studies suggest that the PPAR- ligand rosiglitazone increased secretion of TFPI from HAECs. In contrast, Western blotting suggested that rosiglitazone had the unfavorable effect of reducing atheroma TFPI expression. This further suggests that it is difficult to model the complex responses of human atheromas in cell culture studies Figure 4 ; . In any case, we were unable to demonstrate any significant TFPI activity even in untreated atheromas, suggesting that any effect of rosiglitazone on TFPI action may be clinically irrelevant. Carotid endarterectomy has been clearly shown to reduce the risk of subsequent stroke in patients with a recent TIA associated with a tight carotid stenosis; however, population studies suggest that a significant number of patients experience strokes while awaiting revascularization after the initial consultation.25 We therefore sought to use cell and explant cultures to investigate the potential of medication to acutely reduce thromboembolic events. The ability of cell culture to model the environment of the human atheroma is limited owing to the complex nature of the cellular and cytokine interactions in vivo. For example, in cell culture, TF must be upregulated in endothelial cells by added cytokines, whereas this is already the case in atheromas in vivo.24 Similarly, explant culture can only give a guide to the response of the atheroma over the short term in vivo, which is the period of interest in patients with symptomatic carotid atheromas. The heterogeneous nature of atheromas complicates drug incubation studies of this type. We therefore used paired, targeted biopsy specimens from the macroscopically diseased PICA and CCA. This approach controlled for patient difference, but even adjacent biopsy specimens from a macroscopically similar site may differ. In preliminary studies, we found that the coefficient of variation for TF in paired biopsy specimens was low at 5%. The inclusion of samples from patients who were receiving similar medication all were prescribed statins and antiplatelet drugs ; and the repetition of studies in 144 biopsy specimens support the validity of our findings. We thought that this was the most appropriate way to establish a medication for human trials of acute plaque stabilization. Another alternative would have been to study an animal model. However, the complex nature of human advanced unstable carotid atheromas is difficult to replicate, even in knockout mouse models.22, 25 A number of the cytokine changes that are seen in human atherosclerosis are not demonstrated in mouse models.25 Two recent trials examined the effects of fenofibrate and pioglitazone on cardiovascular events in patients with diabetes, although both studies were not designed to examine stroke as a primary outcome and did not specifically include patients with significant or symptomatic carotid atherosclerosis.26, 27 The FIELD study, in which 9795 patients were randomized between the PPAR- ligand fenofibrate and placebo, reported a reduction in total cardiovascular events but not stroke, although the results were confounded by the fact that more than twice as many patients in the placebo group commenced statin therapy.26 The PROACTIVE study, which randomized 5238 patients between the PPAR- ligand and buy atenolol.

Indicating that PPAR does not exert posttranslational modification of eNOS activity. This seems to be in contrast with cases of other nuclear receptors such as estrogen receptor36 and glucocorticoid receptor, 37 both of which are capable of stimulating phosphatidylinositol 3-kinase PI3-K ; and Akt PKB. Simoncini et al36 have shown that WY14643 failed to activate PI3-K activity in PPAR immunoprecipitates. However, it is not possible from our results to determine the effect of fenofibrate on phosphorylation of eNOS. Further studies will be needed to clarify this issue. Analysis of the human eNOS promoter sequence 1600 to 22 nucleotides ; did not reveal the presence of any discernible PPAR response elements, 38 suggesting that PPAR may not directly interact with eNOS promoter region.

TABLE 2: Clinical Adverse Reactions Occurring in 2% of Patients Treated with ZETIA Co-Administered with a Statin and at an Incidence Greater than Statin, Regardless of Causality ZETIA + All Statins All Statins Body System Organ Class % ; % ; Adverse Reaction n 9361 n 11, 308 Gastrointestinal disorders Diarrhea 2.2 2.5 General disorders and administration site conditions Fatigue 1.6 2.0 Infections and infestations Influenza 2.1 2.2 Nasopharyngitis 3.3 3.7 Upper respiratory tract infection 2.8 2.9 Musculoskeletal and connective tissue disorders Arthralgia 2.4 2.6 Back pain 2.3 2.4 Myalgia 2.7 3.2 Pain in extremity 1.9 2.1 All Statins all doses of all statins Combination with Fenofibrate: This clinical study involving 625 patients with mixed dyslipidemia age range 20-76 years, 44% women, 79% Caucasians, 0.1% Blacks, 11% Hispanics, 5% Asians ; treated for up to 12 weeks and 576 patients treated for up to an additional 48 weeks evaluated co-administration of ZETIA and fenofibrate. This study was not designed to compare treatment groups for infrequent events. Incidence rates 95% CI ; for clinically important elevations 3 X ULN, consecutive ; in hepatic transaminase levels were 4.5% 1.9, 8.8 ; and 2.7% 1.2, 5.4 ; for fenofibrate monotherapy n 188 ; and ZETIA coadministered with fenofibrate n 183 ; , respectively, adjusted for treatment exposure. Corresponding incidence rates for cholecystectomy were 0.6% 95% CI: 0.0%, 3.1% ; and 1.7% 95% CI: 0.6%, 4.0% ; for fenofibrate monotherapy and ZETIA co-administered with fenofibrate, respectively [see Drug Interactions 7.3 ; ]. The numbers of patients exposed to co-administration therapy as well as fenofibrate and ezetimibe monotherapy were inadequate to assess gallbladder disease risk. There were no CPK elevations 10 X ULN in any of the treatment groups. 6.2 Post-marketing Experience Because the reactions below are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The following additional adverse reactions have been identified during post-approval use of ZETIA: Hypersensitivity reactions, including anaphylaxis, angioedema, rash, and urticaria; arthralgia; myalgia; elevated creatine phosphokinase; myopathy rhabdomyolysis [see Warnings and Precautions 5.3 ; ]; elevations in liver transaminases; hepatitis; thrombocytopenia; pancreatitis; nausea; dizziness; paresthesia; depression; cholelithiasis; cholecystitis. DRUG INTERACTIONS [See Clinical Pharmacology 12.3 ; .] 7.1 Cyclosporine Caution should be exercised when using ZETIA and cyclosporine concomitantly due to increased exposure to both ezetimibe and cyclosporine. Cyclosporine concentrations should be monitored in patients receiving ZETIA and cyclosporine. The degree of increase in ezetimibe exposure may be greater in patients with severe renal insufficiency. In patients treated with cyclosporine, the potential effects of the increased exposure to ezetimibe from concomitant use should be carefully weighed against the benefits of alterations in lipid levels provided by ezetimibe. 7.2 Fibrates The efficacy and safety of co-administration of ezetimibe with fibrates other than fenofibrate have not been studied. Fibrates may increase cholesterol excretion into the bile, leading to cholelithiasis. In a preclinical study in dogs, ezetimibe increased cholesterol in the gallbladder bile [see Nonclinical Toxicology 13.2 ; ]. Co-administration of ZETIA with fibrates other than fenofibrate is not recommended until use in patients is adequately studied. 7.3 Fenofibrate If cholelithiasis is suspected in a patient receiving ZETIA and fenofibrate, gallbladder studies are indicated and alternative lipid-lowering therapy should be considered [see Adverse Reactions 6.1 ; and the product labeling for fenofibrate]. 7.4 Cholestyramine Concomitant cholestyramine administration decreased the mean area under the curve AUC ; of total ezetimibe approximately 55%. The incremental LDL-C reduction due to adding ezetimibe to cholestyramine may be reduced by this interaction. 7.5 Coumarin Anticoagulants If ezetimibe is added to warfarin, a coumarin anticoagulant, the International Normalized Ratio INR ; should be appropriately monitored. USE IN SPECIFIC POPULATIONS Pregnancy Pregnancy Category C: There are no adequate and well-controlled studies of ezetimibe in pregnant women. Ezetimibe should be used during pregnancy only if the potential benefit justifies the risk to the fetus. In oral gavage ; embryo-fetal development studies of ezetimibe conducted in rats and rabbits during organogenesis, there was no evidence of embryolethal effects at the doses tested 250, 500, 1000 mg kg day ; . In rats, increased incidences of common fetal skeletal findings extra pair of thoracic ribs, unossified cervical vertebral centra, shortened ribs ; were observed at 1000 mg kg day ~10 times the human 8 8.1 7.
