Abstract
PURPOSE The aim of this study was to evaluate the blood pressure-lowering and cholesterol-lowering effects of a fixed-dose combination therapy using candesartan (CND)/rosuvastatin (RSV) compared with CND or RSV monotherapy in patients with hypertension and hypercholesterolemia. METHODS This study was a 12-week, randomized, double-blind, placebo-controlled, multicenter study. A total of 394 patients were screened. After a 4-week run-in period, 219 of these patients with hypertension and primary hypercholesterolemia were randomized. Patients received 1 of 3 regimens for 8 weeks: (1) CND 32 mg/RSV 20 mg, (2) RSV 20 mg, or (3) CND 32 mg. The primary outcome variables were changes in the systolic blood pressure (SBP) and diastolic blood pressure (DBP) and the percentage changes in LDL-C from baseline to the drug treatment at 8 weeks. The secondary outcome variables were percentage changes of total cholesterol, triglycerides, HDL-C, non-HDL-C, apolipoprotein B, apolipoprotein A-I, high-sensitivity C-reactive protein, and glucose metabolic indices, including percentage changes of the homeostasis model assessment of insulin resistance (HOMA-IR), adiponectin, and hemoglobin A1c. Tolerability of combination therapy was compared with other monotherapy groups. FINDINGS The percentage changes of LDL-C were -48.6% (from 157.2 to 80.1 mg/dL) in the RSV group and -49.8% (from 160.2 to 78.9 mg/dL) in the CND/RSV group from baseline to the end of 8 weeks of treatment. Mean SBP and DBP were significantly decreased in the CND/RSV and CND groups after 8 weeks (P < 0.001 for all); however, no significant differences were found between the 2 groups. Total cholesterol levels, triglycerides, non-HDL-C, and apolipoprotein B were significantly reduced in the CND/RSV and RSV groups, with no significant differences between the groups compared with the CND group (P < 0.001 for all). The percentage changes of HOMA-IR, adiponectin, and hemoglobin A1c had no significant differences between the combination groups and monotherapy groups. However, in a 2-sample t test, HOMA-IR was significantly decreased in the CND/RSV group compared with the RSV group in nondiabetic patients (mean [SD] percentage change of HOMA-IR, -8.7% [37.6%] vs 17.1% [53.1%]; P = 0.048). There were no significant differences in metabolic indices between the diabetic groups. Adverse events in the CND/RSV group were similar to those in the monotherapy group. IMPLICATIONS Once-daily fixed-dose combination therapy with CND/RSV is an effective, tolerable, convenient treatment option for patients with essential hypertension and hypercholesteremia.

Abstract
BACKGROUND Lanosterol demethylase is an enzyme that is essential for fungal growth and catalyzes an early step in the biosynthetic pathway of ergosterol, which is a sterol that is required for fungal cell membrane formation and integrity. Lanosterol demethylase is the molecular target of the class of drugs referred to as "azole antifungals." VT-1161 is a novel, oral, selective inhibitor of fungal lanosterol demethylase and is being developed for the treatment of recurrent vulvovaginal candidiasis. OBJECTIVE We evaluated the efficacy and safety of 4 dosing regimens of oral VT-1161 compared with placebo in women with recurrent vulvovaginal candidiasis, which was defined as at least 3 symptomatic episodes of acute vulvovaginal candidiasis within a 12-month period. STUDY DESIGN Two hundred fifteen women with a documented history of recurrent vulvovaginal candidiasis and who, at screening, were experiencing an episode of acute vulvovaginal candidiasis (acute vulvovaginal candidiasis; composite vulvovaginal signs and symptoms score of ≥3 and a positive potassium hydroxide test for yeast) were enrolled. After treatment of the acute infection with fluconazole, subjects were assigned randomly to 1 of 5 treatment regimens: (1) VT-1161 150 mg once daily for 7 days, then 150 mg once weekly for 11 weeks, followed by a once-weekly dose of placebo for 12 weeks; (2) VT-1161 300 mg once daily for 7 days, then 300 mg once weekly for 11 weeks, followed by a once-weekly dose of placebo for 12 weeks; (3) VT-1161 150 mg once daily for 7 days, then 150 mg once weekly for 23 weeks; (4) VT-1161 300 mg once daily for 7 days, then 300 mg once weekly for 23 weeks; or (5) a matching placebo regimen for 24 weeks. The primary efficacy outcome was the proportion of subjects with ≥1 culture-verified acute vulvovaginal candidiasis episodes through week 48. RESULTS In the intent-to-treat population, the proportion of subjects with ≥1 acute vulvovaginal candidiasis episodes ranged from 0-7% across the 4 VT-1161 arms vs 52% in the placebo arm, with all arms achieving statistical significance vs placebo. VT-1161 was well-tolerated with a favorable safety profile, and the incidence of adverse events was lower in all VT-1161 arms compared with placebo. In addition, no patient in any VT-1161 arm discontinued the study early because of an adverse event or laboratory abnormality. There was also no evidence of an adverse effect of VT-1161 on liver function or electrocardiogram recordings. CONCLUSION In this study, VT-1161 was shown to be efficacious and safe in the treatment of patients with recurrent vulvovaginal candidiasis. These data strongly support further clinical investigation of VT-1161 for the treatment of recurrent vulvovaginal candidiasis.

Abstract
BACKGROUND Cholesterol and blood pressure (BP) can be effectively and safely lowered with statin drugs and BP-lowering drugs, reducing major cardiovascular (CV) events by 20%-30% within 5 years in high-risk individuals. However, there are limited data in lower-risk populations. The Heart Outcomes Prevention Evaluation-3 (HOPE-3) trial is evaluating whether cholesterol lowering with a statin drug, BP lowering with low doses of 2 antihypertensive agents, and their combination safely reduce major CV events in individuals at intermediate risk who have had no previous vascular events and have average cholesterol and BP levels. METHODS A total of 12,705 women 65 years or older and men 55 years or older with at least 1 CV risk factor, no known CV disease, and without any clear indication or contraindication to the study drugs were randomized to rosuvastatin 10 mg/d or placebo and to candesartan/hydrochlorothiazide 16/12.5 mg/d or placebo (2 × 2 factorial design) and will be followed for a mean of 5.8 years. The coprimary study outcomes are the composite of CV death, nonfatal myocardial infarction (MI), and nonfatal stroke and the composite of CV death, nonfatal MI, nonfatal stroke, resuscitated cardiac arrest, heart failure, and arterial revascularization. RESULTS Participants were recruited from 21 countries in North America, South America, Europe, Asia, and Australia. Mean age at randomization was 66 years and 46% were women. CONCLUSIONS The HOPE-3 trial will provide new information on cholesterol and BP lowering in intermediate-risk populations with average cholesterol and BP levels and is expected to inform approaches to primary prevention worldwide (HOPE-3 ClinicalTrials.gov NCT00468923).

Abstract
PURPOSE A fixed-dose combination of a stain and an antihypertensive drug may be useful for the treatment of patients with hypertension and hyperlipidemia. It may also improve patient drug compliance to help control risk factors of cardiovascular disease. This study was designed to evaluate the blood pressure-lowering and cholesterol-lowering effect of a fixed-dose combination of irbesartan-atorvastatin compared with monotherapy by either agent over an 8-week treatment period. METHODS Patients with comorbid hypertension and hypercholesterolemia were screened for this randomized, double-blind, Phase III study. Eligible study patients were randomly assigned to test groups receiving a combination of irbesartan 300 mg and atorvastatin 40 mg or 80 mg (IRB300 + ATO40 and IRB300 + ATO80). Comparator groups comprised monotherapy groups with irbesartan 300 mg (IRB300) or atorvastatin 40 mg (ATO40) or atorvastatin 80 mg (ATO80), or placebo. Patients who were eligible at screening were subjected to a 4- to 6-week washout period before commencing 8 weeks of therapy per their assigned group. The primary efficacy end points were percent change in LDL-C and sitting diastolic blood pressure (DBP) levels from baseline to end of therapy. Tolerability profiles of combination therapy were compared with other groups. FINDINGS A total of 733 patients with comorbid hypertension and hypercholesterolemia were screened for this study; 230 eligible patients were randomized to treatment. The mean age of patients was 58.9 (8.5) years, and their mean body mass index was 25.8 (3.2) kg/m2. More than two thirds (70.9%) of the study patients were male. Mean LDL-C and sitting DBP levels at baseline were 149.54 (29.19) mg/dL and 92.32 (6.03) mm Hg, respectively. Percent reductions in LDL-C after 8 weeks were 46.74% (2.06%) in the IRB300 + ATO40 group and 48.98% (2.12%) in the IRB300 + ATO80 group; these values were 47.13% (3.21%) and 48.30% (2.98%) in the ATO40 and ATO80 comparator groups. Similarly, a reduction in sitting DBP after 8 weeks was -8.50 (1.06) mm Hg in the IRB300 + ATO40 group and 10.66 (1.08) mm Hg in the IRB300 + ATO80 group compared with 8.40 (1.65) mm Hg in the IRB300 group. The incidence rate for treatment-emergent adverse events was 22.27% and was similar between the monotherapy and combination groups. IMPLICATIONS A once-daily combination product of irbesartan and atorvastatin provided an effective, safe, and more compliable treatment for patients with coexisting hypertension and hyperlipidemia.

Abstract
UNLABELLED Simultaneous inhibition of the renin-angiotensin-aldosterone system and the system of degradation of natriuretic peptides can potentially provide unique therapeutic effects in patients with chronic heart failure (CHF) with reduced ejection fraction (EF). Aim of this study was to assess tolerability of therapy with LCZ696--first representative of a class of inhibitors of angiotensin receptor and neutral endopeptidase neprilysin--and to study its pharmacodynamic effects. METHODS We included into open uncontrolled study 30 patients with stable functional class II-III CHF and EF ≤ 40%. After 24-hour run-in period during which angiotensin converting enzyme inhibitors (ACEI) were withdrawn the patients were given LCZ696 (100 mg/day for 7 days followed by 200 mg/day for 14 days). Other CHF therapy remained unchanged. RESULTS Transition from therapy with ACEI to LCZ696 was well tolerated. Three patients were excluded because of hyperkalemia ≥ 5mmol/l. After 21 days of treatment elevation of plasma biomarkers of inhibition of neprilysin and angiotensin receptors occurred: cyclic guanosine monophosphate, renin concentration and activity rose 1.38, 3.50, and 2.27 times from baseline level (p < 0.05 for all). After 7 and 21 days of LCZ696 administration we noted significant lowering of NT-proBNP; significant lowering of aldosterone and endothelin-1 in blood plasma, was observed on day 21. CONCLUSION Administration of LCZ696 to patients with CHF with reduced ejection fraction (EF) was well tolerated and associated with potentially favorable for this category of patients dynamics of biomarkers.

Cleveland Clinic journal of medicine. 2015;(10):693-701
Abstract
The PARADIGM-HF trial (Prospective Comparison of ARNI With ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure) found a combination drug containing sacubitril (a neprilysin inhibitor) and valsartan (an angiotensin II receptor blocker) superior to enalapril (an angiotensin-converting enzyme inhibitor) in patients with systolic heart failure. Recently approved by the US Food and Drug Administration, sacubitril-valsartan is the first new drug in over a decade to decrease death rates in patients with systolic heart failure.

Abstract
OBJECTIVES Whether angiotensin II receptor blockade improves skeletal muscle fatty acid oxidation in overweight and obese humans is unknown. The purpose of the study was to test the hypothesis that the angiotensin II receptor blocker, olmesartan, would increase fatty acid oxidation and the activity of enzymes associated with oxidative metabolism in skeletal muscle of overweight and obese humans. METHODS A total of 12 individuals (6 men and 6 women) aged 18-75 and with a body mass index ⩾25 kg/m2 were assigned to olmesartan or placebo for 8 weeks in a crossover fashion. Fatty acid oxidation was measured before and after each intervention by counting the (14)CO2 produced from [1-(14)C] palmitic acid in skeletal muscle homogenates. RESULTS Fatty acid oxidation was not significantly different between treatment periods at baseline and post intervention. In addition, the enzyme activities of citrate synthase and β-hydroxyacyl-coenzyme A dehydrogenase in skeletal muscle homogenates did not differ between treatment periods at baseline or post intervention. CONCLUSIONS Treatment with olmesartan for 8 weeks does not improve fatty acid oxidation or the activity of enzymes associated with oxidative metabolism in skeletal muscle from overweight and obese individuals. Taken together, our results indicate that improvements in skeletal muscle metabolism are not among the additional benefits of olmesartan that extend beyond blood pressure reduction.

Abstract
PURPOSE The objective of this study was to evaluate the efficacy and safety of a fimasartan/amlodipine combination in patients with hypertension and to determine the optimal composition for a future single-pill combination formulation. METHODS This Phase II study was conducted by using a randomized, multicenter, double-blind, placebo-controlled, 3 × 3 factorial design. After a 2-week placebo run-in period, eligible hypertensive patients (with a sitting diastolic blood pressure [SiDBP] between 90 and 114 mm Hg) were randomized to treatment. They received single or combined administration of fimasartan at 3 doses (0, 30, and 60 mg) and amlodipine at 3 doses (0, 5, and 10 mg) for 8 weeks. The primary efficacy end point was the change in SiDBP from baseline and at week 8; secondary end points included the change in SiDBP from baseline and at week 4 and the changes in sitting systolic blood pressure from baseline and at weeks 4 and 8. Treatment-emergent adverse events (AEs) were also assessed. FINDINGS 420 Korean patients with mild to moderate hypertension were randomly allocated to the 9 groups. Mean (SD) SiDBP changes in each group after 8 weeks were as follows: placebo, -6.0 (8.5) mm Hg; amlodipine 5 mg, -10.6 (9.2) mm Hg; amlodipine 10 mg, -15.9 (7.2) mm Hg; fimasartan 30 mg, -10.1 (9.1) mm Hg; fimasartan 60 mg, -13.0 (10.0) mm Hg; fimasartan 30 mg/amlodipine 5 mg, -16.2 (8.5) mm Hg; fimasartan 30 mg/amlodipine 10 mg, -19.5 (7.5) mm Hg; fimasartan 60 mg/amlodipine 5 mg, -16.6 (6.9) mm Hg; and fimasartan 60 mg/amlodipine 10 mg, -21.5 (8.3) mm Hg. All treatment groups produced significantly greater reductions in blood pressure compared with the placebo group. In addition, all combination treatment groups had superior reductions in blood pressure compared with the monotherapy groups. In the combination treatment groups, doubling fimasartan dose in the given dose of amlodipine did not show further BP reduction, whereas doubling amlodipine dose showed significantly further BP reduction in the given dose of fimasartan. During the study period, 75 (17.9%) of 419 patients experienced 110 AEs. Ninety-five AEs were mild, 9 were moderate, and 6 were severe in intensity. Eight patients discontinued the study due to AEs. There was no significant difference in incidence of AEs among groups (P = 0.0884). The most common AE was headache (12 patients [2.9%]), followed by dizziness (11 patients [2.6%]) and elevated blood creatine phosphokinase levels (6 patients [1.4%]). IMPLICATIONS Fimasartan combined with amlodipine produced superior blood pressure reductions and low levels of AEs compared with either monotherapy. Therefore, a single-pill combination with fimasartan 60 mg/amlodipine 10 mg will be developed. ClinicalTrials.gov: NCT01518998.

Derosa, G, Cicero, AF, Carbone, A, Querci, F, Fogari, E, D'Angelo, A, Maffioli, P
Inflammation. 2014;(1):154-62
Abstract
This study aims to evaluate the effects of an angiotensin receptor blocker (ARB)/calcium channel blocker combination on blood pressure control, lipid profile, insulin sensitivity, and inflammation markers. We randomized 276 hypertensive patients to olmesartan 20 mg, amlodipine 10 mg, or a single pill containing an olmesartan/amlodipine combination 20/5 mg for 12 months. We evaluated the following: body weight, systolic and diastolic blood pressure, fasting plasma glucose, fasting plasma insulin (FPI), M value, lipid profile, adiponectin (ADN), high sensitivity C-reactive protein (Hs-CRP), monocyte chemoattractant protein-1 (MCP-1), and macrophage migration inhibitory factor-1β (MIP-1β). Olmesartan/amlodipine combination better reduced blood pressure, FPI, homeostasis model assessment index, and increased M value and ADN compared to olmesartan and amlodipine monotherapies. Olmesartan/amlodipine significantly decreased Hs-CRP, MCP-1, and MIP-1β. In this multicenter, randomized, double-blind, clinical study, ARB/calcium antagonist combination resulted to be more effective than single monotherapies in reducing blood pressure, in improving insulin sensitivity, and in reducing inflammation parameters in patients with stage I essential hypertension.

The effects of fluid balance and colloid administration on outcomes in patients with aneurysmal subarachnoid hemorrhage: a propensity score-matched analysis.
Ibrahim, GM, Macdonald, RL
Neurocritical care. 2013;(2):140-9
Abstract
BACKGROUND Delayed ischemic neurological deficit (DIND) following aneurysmal subarachnoid hemorrhage (SAH) remains a significant cause of mortality and disability. The administration of colloids and the induction of a positive fluid balance during the vasospasm risk period remain controversial. Here, we compared DIND and outcomes among propensity score-matched cohorts who did and did not receive colloids and also tested the effect of a positive fluid balance on these endpoints. METHODS Exploratory analysis was performed on 413 patients enrolled in CONSCIOUS-1, a prospective randomized trial of clazosentan for the prevention of angiographic vasospasm. Propensity score matching was performed on the basis of age, gender, pre-existing heart conditions, hypertension, nicotine use, World Federation of Neurosurgical Societies scores, aneurysm location, clazosentan treatment, subarachnoid clot burden, and severity of angiographic vasospasm. Inferential statistics were used for group-wise comparisons. RESULTS One hundred twenty-three subjects were matched (41 received colloids, whereas 82 did not). The covariate balance and propensity score distributions were acceptable. There was no difference between the groups with respect to DIND (17 vs. 22%; p = 0.64) or the presence (48 vs. 51%; p = 0.71) or volume of delayed infarcts (volume >7.5 cm3; 62 vs. 48%; p = 0.41). Similarly, no differences were found on multivariate analysis between patients who did and did not have a positive fluid balance, although patients with severe angiographic vasospasm had more delayed infarcts with a negative fluid balance (p = 0.01). Among all subjects, the administration of colloids and a positive fluid balance were associated with worse outcomes on the NIHSS (p = 0.04) and modified Rankin (p = 0.02) scales, respectively. CONCLUSIONS Colloid administration and induction of a positive fluid balance during the vasospasm risk period may be associated with poor outcomes in specific patient groups. Patient selection is of utmost importance when managing the fluid status of patients with aneurysmal SAH.
