Introduction
Nicotine replacement therapy (NRT) benefits smokers who wish to quit; nicotine gum represents one NRT. New formulations of nicotine gum have been developed to consider consumer preferences and needs. A new mint-flavored nicotine gum with a different texture was developed that may provide a more appealing taste and chewing experience. This study evaluated this new nicotine gum (2 and 4 mg strengths) for bioequivalence versus the original flavor sugar-free nicotine gum at corresponding dosages.Methods
All subjects randomized in this crossover study received a single dose of all treatments, i.e., 2 and 4 mg doses of test and reference gums, separated by 2–7 days of washout between treatments. Subjects’ maximal plasma nicotine concentration (Cmax) and extent of nicotine absorption (AUC0–t) following the administration of each treatment were calculated from plasma nicotine concentrations. Ratios of test/reference for Cmax and AUC0–t were calculated to evaluate bioequivalence between the two products.Results
Both 2 and 4 mg doses of the new mint-flavored nicotine gum were bioequivalent to the dose-matched reference product as determined by the ratio of the geometric means and their 90% confidence intervals for Cmax and AUC0–t as well as secondary pharmacokinetic parameters. The safety profiles of the test and reference gums were similar; all treatments were well tolerated.Conclusions
A new mint-flavored nicotine gum with modified taste and texture is bioequivalent to the original flavor sugar-free nicotine gum at both the 2 and 4 mg dosage strengths and has a similar safety profile.Funding

Introduction
There is a growing interest in nutraceuticals improving cardiovascular risk factor levels and related organ damage.Methods
This double-blind, placebo-controlled randomized clinical trial aims to compare the effect of a combined nutraceutical containing red yeast rice (10 mg), phytosterols (800 mg), and l-tyrosol (5 mg) on lipid profile, blood pressure, endothelial function, and arterial stiffness in a group of 60 patients with polygenic hypercholesterolemia resistant to Mediterranean diet.Results
After 8 weeks of treatment, when compared to the placebo group, the active treated patients experienced a more favorable percentage change in total cholesterol (?16.3% vs 9.9%, P < 0.001 always), LDL-C (?23.4% vs ?13.2%, P < 0.001 always), and hepatic steatosis index (?2.8%, P < 0.01 vs ?1.8%, P < 0.05). Moreover, ALT (?27.7%, P < 0.001), AST (?13.8%, P = 0.004), and serum uric acid (?12.3%, P = 0.005) were reduced by the tested nutraceutical compound both compared to randomization and to placebo, which did not affect these parameters (P < 0.01 for all). Regarding the hemodynamic parameters, there was a decrease of systolic blood pressure (?5.6%) with the active treatment not observed with placebo (P < 0.05 vs baseline and placebo) and endothelial reactivity improved, too (?13.2%, P < 0.001 vs baseline). Consequently, the estimated 10-year cardiovascular risk score improved by 1.19% (SE 0.4%) (P = 0.01) in the nutraceutical-treated patients.Conclusion
The tested nutraceutical association is able to improve the positive effects of a Mediterranean diet on a large number of CV risk factors and consequently of the estimated CV risk.Trial registration

Introduction
Azilsartan is an angiotensin II receptor blocker indicated for the treatment of patients with hypertension. The efficacy and safety of azilsartan are established in adults, but have not been evaluated in pediatric patients, nor has its pharmacokinetic profile been determined in pediatric patients.Methods
In this phase 3, open-label, multicenter study, we investigated the pharmacokinetics and safety of single doses of azilsartan in six Japanese patients with hypertension, aged 9–14 years. The dose of azilsartan was 5 mg for three patients weighing less than 50 kg, with mean body weight at baseline of 27.5 kg, and 10 mg for three patients weighing at least 50 kg, with mean body weight at baseline of 65.9 kg.Results
Mean maximum plasma concentration (Cmax) of azilsartan was 888.3 and 831.3 ng/mL and median time to maximum concentration (Tmax) of unchanged azilsartan was 3.0 and 4.0 h, in the 5-mg and 10-mg groups, respectively. Mean areas under the plasma concentration–time curve (AUC) from 0–24 h post-dose (AUC0–24) and 0 h to infinity (AUC0–inf) were 6350.3 and 6635.7 ng h/mL, respectively, in the 5-mg group, and 6871.7 and 7433.3 ng h/mL, respectively, in the 10-mg group. Both doses were well tolerated; no treatment-emergent adverse events considered to be related to azilsartan occurred during the study.Conclusion
Our data suggest that pediatric patients weighing less than 50 kg may have? approximately 2-fold greater exposure to azilsartan than those weighing at least 50 kg at the same dose. Exposure to azilsartan in children weighing at least 50 kg is comparable to that in healthy adults at the same dose.Trial Registration

Introduction
Tiotropium bromide has been widely used in clinical practice, while theophylline is another treatment option for chronic obstructive pulmonary disease (COPD). However, only a few relevant studies have investigated the long-term outcomes and efficacy of both in patients with COPD. We evaluated the effects of tiotropium and low-dose theophylline on stable COPD patients of groups B and D.Methods
Eligible participants (n?=?170) were randomized and received either tiotropium 18 µg once daily with theophylline 100 mg twice daily (Group I) or tiotropium 18 µg once daily (Group II) for 6 months. COPD assessment test (CAT), modified Medical Research Council (mMRC) dyspnea scores and pulmonary function tests were measured before randomization and during the treatment.Results
After 6 months of treatment, the CAT scores in both groups decreased significantly (11.41?±?3.56 and 11.08?±?3.05, p?<?0.0001). The changes of CAT (p?=?0.028) and mMRC scores (p?=?0.049) between the two groups differed after 1 month of treatment. In Group I, forced expiratory flow after 25% of the FVC% predicted (MEF25% pred) was significantly improved after 3 months (4.84?±?8.73%, p?<?0.0001) and 6 months (6.21?±?8.65%, p?<?0.0001). There was a significant difference in small airway function tests (MEF50% pred, MEF25% pred, and MMEF% pred) between the two groups after 6 month of treatment (p?=?0.003, p?<?0.0001, and p?=?0.021, respectively).Conclusions
Tiotropium combined with low-dose theophylline significantly improved the symptoms and general health of patients with stable COPD of groups B and D after 6 months of follow-up. Additionally, this therapy also improved the indicators of small airway function.Trial Registration

Objective
To investigate the effect of enteral Synbiotic 2000 FORTE® (a mixture of lactic acid bacteria and fibre) on the incidence of ventilator associated pneumonia (VAP) in critically ill patients.Design
Prospective, randomised, double blind, placebo controlled trial.Setting
Tertiary referral centre, general Adult Intensive Care Unit (ICU).Patients and participants
259 enterally fed patients requiring mechanical ventilation for 48 h or more were enrolled.Intervention
All patients were enterally fed as per a standard protocol and randomly assigned to receive either synbiotic 2000 FORTE® (twice a day) or a cellulose-based placebo for a maximum of 28 days.Measurements and results
Treatment group (n = 130) was well matched with placebo group (n = 129) for age (mean 49.5 and 50 years, respectively) and APACHE II score (median 17 for both). Oropharyngeal microbial flora and colonisation rates were unaffected by synbiotics. The overall incidence of VAP was lower than anticipated (11.2%) and no statistical difference was demonstrated between groups receiving synbiotic and placebo in the incidence of VAP (9 and 13%, P = 0.42), VAP rate per 1,000 ventilator days (13 and 14.6, P = 0.91) or hospital mortality (27 and 33%, P = 0.39), respectively.Conclusions
Enteral administration of Synbiotic 2000 FORTE® has no statistically significant impact on the incidence of VAP in critically ill patients.6.
Introduction
Mifepristone, a competitive glucocorticoid receptor antagonist approved for Cushing syndrome, and ketoconazole, an antifungal and steroidogenesis inhibitor, are both inhibitors of and substrates for cytochrome P450 (CYP3A4). This study evaluated the pharmacokinetic effects of concomitant ketoconazole, a strong CYP3A4 inhibitor, on mifepristone.Methods
In an open-label, two-period, single-center study, healthy adult men received mifepristone 600 mg orally daily for 12 days (period 1) followed by mifepristone 600 mg daily plus ketoconazole 200 mg orally twice daily for 5 days (period 2). Serial pharmacokinetic blood samples were collected predose and over 24 h postdose on days 12 (period 1) and 17 (period 2). A cross-study comparison (using data on file) further examined whether systemic exposure to mifepristone plus ketoconazole exceeded the exposure following mifepristone 1200 mg orally administered for 7 days.Results
Sixteen subjects were enrolled and 14 completed the study. Concomitant administration with ketoconazole increased the systemic exposure to mifepristone, based on geometric least squares mean ratios, by 28% for C max and 38% for AUC0–24. This increase was 85% and 87% of the exposure observed following mifepristone’s highest label dose of 1200 mg/day for C max and AUC0–24, respectively. Adverse events (AEs) were reported in 56.3% (9/16) of subjects during administration of mifepristone alone and in 57.1% (8/14) during combination with ketoconazole. No serious AEs were reported.Conclusion
Systemic exposure to mifepristone increased following multiple doses of mifepristone 600 mg daily plus ketoconazole 200 mg twice daily. Little to no increase in AEs occurred. Dose adjustment of mifepristone may be needed when given with ketoconazole.Funding

Introduction
In our previous study investigating effects of luseogliflozin, a sodium–glucose cotransporter 2 inhibitor, on 24-h glycemic variability by continuous glucose monitoring (CGM), luseogliflozin elicited parallel downward shifts in fasting and postprandial glucose levels. However, further review of individual patients’ data revealed that postprandial hyperglycemia was not reduced in some patients, while preprandial glucose was ameliorated in most patients. Therefore, we divided patients into two groups according to their postprandial glucose responses and conducted a post hoc subanalyses to elucidate which factors contributed to the differential effects of luseogliflozin.Methods
Thirty-four Japanese type 2 diabetic patients in our previous randomized, double-blind, placebo-controlled, crossover study with 7-day luseogliflozin administration were divided into postprandial glucose responders (PGR, n = 23, ameliorated peak glucose) and postprandial glucose non-responders (PGNR; n = 11, non-ameliorated peak glucose). Baseline characteristics, variations in CGM-measured 24-h glucose levels, and other pharmacodynamic variabilities were compared.Results
Baseline characteristics did not differ significantly between groups. Placebo-subtracted peak glucose was significantly lowered in PGR and significantly increased in PGNR (?43.8 and 17.9 mg/dL; both p < 0.05). Luseogliflozin significantly lowered “lowest glucose” (defined as the lowest level measured throughout a 24-h period) similarly in PGR and PGNR (?19.2 and ?24.0 mg/dL; both p < 0.05), significantly reduced the mean amplitude of glucose excursions in PGR (?15.50 mg/dL; p < 0.05), and increased the area under the curve for plasma glucagon over 24 h in PGNR (median difference vs. placebo: 240 pg/mL h; p < 0.05). Luseogliflozin increased urinary glucose excretion (UGE) and decreased serum insulin by similar magnitudes in both groups.Conclusions
Luseogliflozin diminished glucose fluctuations in most patients by lowering peak glucose to a greater extent than lowest glucose. Luseogliflozin may also lower lowest glucose in patients whose peak glucose was not ameliorated despite increasing UGE. The glucagon increase in PGNR might explain its hypoglycemic effect on postprandial glucose.Funding

Introduction
Healthy eating is a critical aspect of the prevention and management of type 2 diabetes (T2DM). Disrupted eating patterns can result in poor glucose control and increase the likelihood of diabetic complications. Teneligliptin inhibits dipeptidyl peptidase-4 activity for 24 h and suppresses postprandial hyperglycemia after all three daily meals. This interim analysis of data from the large-scale post-marketing surveillance of teneligliptin (RUBY) in Japan examined eating patterns and their relationship with metabolic parameters and diabetic complications. We also examined whether eating patterns affected safety and efficacy of teneligliptin.Methods
We analyzed baseline data from survey forms collected in RUBY between May 2013 and June 2017, including patient characteristics, metabolic parameters, and eating patterns (eating three meals per day or not; timing of evening meal) before teneligliptin treatment was initiated. Safety and efficacy of 12 months’ teneligliptin (20–40 mg/day) treatment was assessed.Results
Data from 10,532 patients were available for analysis. Most patients who did not eat three meals per day (n??=757) or who ate their evening meal after 10 PM (n??=206) were 64 years old or younger. At baseline, glycated hemoglobin (HbA1c), fasting blood glucose, triglycerides, total and low-density lipoprotein cholesterol, body mass index, alanine aminotransferase, and aspartate aminotransferase levels were higher in those patients who did not eat three meals per day (p?<?0.05) or who ate their evening meal late (p?<?0.05). Diabetic complications were more common in patients who did not eat three meals per day. Treatment with teneligliptin reduced HbA1c over 6 or 12 months across all eating patterns, with a low incidence of adverse drug reactions.Conclusions
Eating patterns may be associated with altered metabolic parameters and diabetic complications among Japanese patients with T2DM. Teneligliptin may be well tolerated and improve hyperglycemia in patients with T2DM irrespective of eating patterns.Funding

Introduction
The PARP inhibitor olaparib is efficacious as monotherapy and has potential application in combination with endocrine therapy for the treatment of breast cancer. This phase I study assessed the safety and pharmacokinetic (PK) profiles of olaparib combined with tamoxifen, anastrozole or letrozole in patients with advanced solid tumours.Methods
During part A, PK profiles were assessed in three consecutive treatment periods: (1) olaparib (tablet) 300 mg bid, days 1–5 followed by a 4-day washout; (2) cohort 1, tamoxifen 60 mg loading dose qd days 10–13, 20 mg qd days 14–26; cohort 2, anastrozole 1 mg qd days 10–19; cohort 3, letrozole 2.5 mg qd days 10–38; (3) as for period 2, with concomitant olaparib 300 mg bid for 5 days. Patients could then enter part B and receive olaparib monotherapy (300 mg bid continuously). Safety was assessed in parts A and B until 12 months after the last patient entered part B.Results
Seventy-nine patients (20.3% with breast cancer) received treatment in part A; 72 completed part A and 69 entered part B. Anastrozole and letrozole had no effect on the PK profile of olaparib and vice versa. Co-administration with tamoxifen produced a modest decrease in exposure to olaparib [geometric least-squares mean (GLSmean) Cmax,ss and AUC0–τ decreased by 20% (90% CI 0.71–0.90) and 27% (0.63–0.84), respectively]. Exposure to tamoxifen was slightly increased when combined with olaparib [GLSmean Cmax,ss and AUC0–τ increased by 13% (1.06–1.22) and 16% (1.11–1.21), respectively]; however, the 90% CI fell within the 0.7–1.43 boundary and there were no changes in exposure to tamoxifen metabolites. The safety profile for olaparib alone and in combination with the antihormonal therapies was acceptable.Conclusions
The combination of olaparib and either anastrozole, letrozole or tamoxifen was generally well tolerated, with no clinically relevant PK interactions identified.Funding

Introduction
G protein-coupled receptor 119 (GPR119) is a promising target for the treatment of type 2 diabetes mellitus (T2DM), as both insulin and glucagon-like peptide-1 secretion can be promoted with a single drug. We compared the efficacy and safety of the GPR119 agonist DS-8500a with placebo and sitagliptin 50 mg in Japanese patients with T2DM.Methods
This randomized, double-blind, parallel-group comparison study was conducted in Japan (trial registration NCT02628392, JapicCTI-153068). Eligible patients aged ≥ 20 years with T2DM and hemoglobin A1c (HbA1c) ≥ 7.0% and < 10.0% were randomized to receive placebo, DS-8500a (25, 50, or 75 mg), or sitagliptin 50 mg once daily for 12 weeks. The primary efficacy endpoint was change in HbA1c from baseline to week 12. Secondary endpoints included change in fasting plasma glucose (FPG), glucose AUC0–3h during a meal tolerance test, 2-hour postprandial glucose (2hr-PPG), and changes in lipid parameters (total, low-density lipoprotein (LDL-) and high-density lipoprotein (HDL-) cholesterol, and triglycerides) at week 12. Safety endpoints included adverse events, hypoglycemia, and clinical/laboratory variables.Results
DS-8500a demonstrated dose-dependent HbA1c lowering compared with placebo at week 12: change from baseline ? 0.23% (p = 0.0173), ? 0.37% (p = 0.0001), and ? 0.44% (p < 0.0001) in the 25-mg, 50-mg, and 75-mg groups, respectively. At 50- and 75-mg doses, DS-8500a significantly lowered FPG, glucose AUC0–3h, and 2hr-PPG compared with placebo. The glucose-lowering effect was maintained up to 12 weeks. DS-8500a did not lower any of the above parameters to a greater extent than sitagliptin. Compared with placebo and sitagliptin, DS-8500a 50 and 75 mg significantly reduced total cholesterol, LDL-cholesterol, and triglycerides, and significantly increased HDL-cholesterol. All DS-8500a doses were well tolerated. Two cases of clinically relevant drug-related hypoglycemia occurred in the DS-8500a 50-mg group.Conclusion
DS-8500a was well tolerated and demonstrated significant glucose-lowering effects and favorable changes in lipid profiles up to 12 weeks in Japanese patients with T2DM.Funding

Introduction
Vonoprazan (TAK-438) is a novel potassium-competitive acid blocker that inhibits gastric H+, K+-ATPase. The objectives of this study were to evaluate the influence of triple therapy with vonoprazan–amoxicillin–clarithromycin or vonoprazan–amoxicillin–metronidazole on the pharmacokinetics of each component of the triple therapies (primary) and to evaluate the safety and tolerability of vonoprazan-based triple therapies (secondary) in healthy adults.Methods
In this single-center, phase 1, open-label, randomized, four-way crossover study, Helicobacter pylori-negative, healthy Japanese male subjects were randomly assigned to 1 of 4 treatment sequences in two cohorts (12 subjects per cohort). Each treatment sequence comprised four treatment periods separated by a washout period of 7 or 14 days. Pharmacokinetic parameters for vonoprazan, amoxicillin, clarithromycin and metronidazole in single therapy or triple therapies were assessed. All adverse events were recorded.Results
Compared with single therapy, triple therapy with vonoprazan–amoxicillin–clarithromycin increased the area under the plasma concentration–time curve from time 0–12 h (AUC0-12) and maximum plasma concentration (C max) of plasma vonoprazan free base by 1.846- and 1.868-fold, respectively, and increased the AUC0-12 and C max of plasma clarithromycin by 1.450- and 1.635-fold, respectively. Triple therapy with vonoprazan–amoxicillin–metronidazole had no influence on the pharmacokinetics of vonoprazan or metronidazole. The pharmacokinetics of amoxicillin was not influenced by vonoprazan-based triple therapies. Seven adverse events were reported. Two subjects discontinued because of an adverse event (rash, liver function test abnormal); both events were considered to be study drug-related.Conclusion
In healthy Japanese male subjects, triple therapy with vonoprazan–amoxicillin–clarithromycin increased vonoprazan and clarithromycin exposure. The safety and tolerability profile of triple therapy with vonoprazan–amoxicillin–clarithromycin or vonoprazan–amoxicillin–metronidazole was favorable in this population.Funding

Purpose
To evaluate the efficacy of superselective transcatheter arterial embolization (TAE) in the treatment of acute peripancreatic bleeding complications.Methods
During a 9-year period, 44 patients with acute bleeding of the peripancreatic arteries underwent TAE in our institution. Thirty-eight patients were treated using microcatheters and 6 patients with a diagnostic catheter. Embolic agents included coils (n = 38), polyvinyl alcohol (PVA) particles (n = 2), isobutyl cyanoacrylate (n = 2), coils plus PVA particles (n = 1), and coils plus isobutyl cyanoacrylate (n = 1). Outcome measures included technical success, clinical success, and the rate of complications.Results
Identified bleeding sources included gastroduodenal artery (n = 14), splenic artery (n = 9), pancreaticoduodenal artery (n = 6), common hepatic artery (n = 5), superior mesenteric artery branches (n = 4), proper hepatic artery (n = 3), and dorsal/transverse pancreatic artery (n = 3). Technical success with effective control of active bleeding was achieved in 41/44 patients (93 %). Clinical success attributed to TAE alone was documented in 40/44 patients (91 %). The rate of major complications was 2 % including death in one patient.Conclusions
Superselective TAE allows effective, minimally invasive control of acute peripancreatic bleeding complications with a low rate of therapeutically relevant complications.14.

Introduction
The phase III MPACT trial in patients with metastatic pancreatic cancer (MPC) demonstrated superior efficacy of nab-paclitaxel (nab-P) plus gemcitabine (Gem) compared with Gem monotherapy, including the primary endpoint of overall survival (OS; median 8.7 vs. 6.6 months; hazard ratio [HR] 0.72; P < 0.001). A significant treatment difference favoring nab-P + Gem over Gem was observed for OS in patients treated in North America. The majority of patients were from the US (88%) with only 12% from Canada. Healthcare systems and treatment patterns are different between the 2 countries, and there is limited published information on outcomes of Canadian patients treated with first-line nab-P + Gem. This analysis evaluated efficacy and safety outcomes in Canadian patients in the MPACT trial.Methods
Treatment-naive patients with MPC (N = 861) received either nab-P 125 mg/m2 + Gem 1000 mg/m2 on days 1, 8, and 15 every 4 weeks or Gem 1000 mg/m2 weekly for the first 7 of 8 weeks (cycle 1) and then on days 1, 8, and 15 every 4 weeks (cycle ≥2).Results
The MPACT trial enrolled 63 patients in Canada. Baseline characteristics were well balanced and comparable with those of the intent-to-treat population. Both OS (median 11.9 vs. 7.1 months; HR 0.76; P = 0.373) and progression-free survival (median 7.2 vs. 5.2 months; HR 0.65; P = 0.224) were numerically longer and overall response rate (27% vs. 17%; P = 0.312) was numerically higher with nab-P + Gem vs. Gem. The most common grade ≥3 adverse events with nab-P + Gem vs. Gem were neutropenia (22% vs. 10%), fatigue (34% vs. 33%), and neuropathy (25% vs. 0%).Conclusion
This subanalysis confirmed that nab-P + Gem is an efficacious treatment option and has a manageable safety profile in patients with MPC treated in Canada.Trial registration

Introduction
Amenamevir is a nonnucleoside antiherpes virus compound available for treating herpes zoster infections. Four studies aimed to determine any potential interactions between amenamevir and ketoconazole, rifampicin, midazolam, or warfarin in healthy male participants.Methods
Two studies were open-label studies that evaluated the effects of multiple doses of ketoconazole (400 mg) and rifampicin (600 mg) on the pharmacokinetics of a single oral dose of amenamevir. The other two studies were randomized, double-blind, parallel-group studies that evaluated the effects of multiple doses of amenamevir on the pharmacokinetics of a single dose of midazolam (7.5 mg) and warfarin (25 mg). A drug interaction was considered to occur if the 90% confidence interval (CI) of the least squares geometric mean ratio (GMR) of amenamevir to the comparator was outside the prespecified interval of 0.80–1.25.Results
Interactions were observed between amenamevir and ketoconazole, rifampicin, and midazolam, but not between amenamevir and warfarin. After a single 400-mg dose of amenamevir, the GMRs of amenamevir plus ketoconazole or rifampicin versus amenamevir alone for C max and the area under the plasma concentration–time curve from time zero to infinity (AUCinf) were 1.30 (90% CI 1.17–1.45) and 2.58 (90% CI 2.32–2.87), respectively, for ketoconazole and 0.42 (90% CI 0.37–0.49) and 0.17 (90% CI 0.15–0.19), respectively, for rifampicin. Following multiple doses of amenamevir (400 mg), the GMRs of midazolam plus amenamevir versus midazolam alone for AUCinf and C max were 0.53 (90% CI 0.47–0.61) and 0.63 (90% CI 0.50–0.80), respectively. After a single dose of warfarin, the (S)-warfarin and (R)-warfarin mean C max increased and mean AUCinf decreased in the presence of amenamevir; however, the 90% CIs of the GMRs for these parameters remained within the predefined limits.Conclusion
These findings confirm that amenamevir (as a cytochrome P450 3A4 substrate) can interact with ketoconazole or rifampicin, and (as a cytochrome P450 3A4 inducer) can interact with midazolam; however, no interaction between amenamevir and (S)-warfarin was observed, indicating that amenamevir is not an inducer of cytochrome P450 2C9.Funding

Patients who were previously untreated or required a change in medication were treated with a fixed combination of perindopril/amlodipine (3.5/2.5 or 7.0/5.0 mg) for 12 weeks. Changes in office, home and ambulatory blood pressure (BP) were recorded. Adherence was assessed by the Hill-Bone medication adherence scale.Results
Overall, 1814 patients (mean age 60.0 ± 13.4 years) were included in 614 German practices, and data of 1770 patients were analyzed. At study entry, 97.7% of patients received perindopril/amlodipine at a daily dose of 3.5 mg/2.5 mg, and 47.9% of patients remained on this dose during the study period. Treatment with perindopril/amlodipine decreased mean office BP from 163.7/95.4 to 133.6/80.3 mmHg (p < 0.0001), resulting in a hypertension control rate of 69.1%. Blood pressure control was comparable in previously untreated and treated patients (70.3 vs. 68.1%), and in younger and older patients (70.6 < 65 vs. 66.3% ≥ 65 years). Ambulatory BP measurements were available in a subgroup of patients (n = 167), and mean 24 h ambulatory BP decreased from 150.6 ± 12.6/88.9 ± 8.8 to 132.4 ± 11.9/79.4 ± 8.5 mmHg (p < 0.0001). Furthermore, the proportion of patients with severe hypertension European Society of Hypertension/European Society of Cardiology (ESH/ESC) grade II or III decreased from 64.4 to 3.9%, and patients with pre-existing isolated systolic hypertension (n = 284) converted to normal BP in 67.6% of cases. Nearly half of the patients (47.2%) were perfectly adherent during the study. In previously treated patients, the percentage of patients with perfect adherence increased from 20.6% prior to study to 43.5% at final visit (p < 0.0001). Adverse drug reactions were documented for 4.9% of patients.Conclusion
A fixed-dose combination of perindopril/amlodipine shows significant blood pressure reduction and improvement in medication adherence in a primary care setting.Trial Registration

Introduction
This study aimed to compare the efficacy and safety of two mesalazine formulations in the treatment of Chinese patients with ulcerative colitis (UC) in the remission phase.Methods
In this multicenter, single-blind, randomized controlled study conducted from November 2010 to August 2012, 251 patients with UC from 18 hospitals were enrolled. The patients were randomized to treatment with mesalazine modified-release tablets (MR group, n = 126) or other enteric-coated tablets (EC group, n = 125), at 800 mg three-times daily for 48 weeks. The primary efficacy parameter was the rate of non-emergence of bloody stool. If the lower limit of the 95% confidence interval (CI) of the primary efficacy measure was over ?10%, the modified-release tablets were considered non-inferior to the enteric-coated tablets. The secondary efficacy parameters included the period of non-emergence of bloody stool and the period of non-recurrence of UC. The incidences of adverse events and adverse drug reactions were compared between the two groups.Results
At 48 weeks of maintenance treatment, the rates of non-emergence of bloody stool were 82.99% (95% CI 73.53–92.45%) and 73.30% (95% CI 64.04–82.56%) in the MR and EC groups, respectively, and the difference between the two groups was 9.69% (95% CI ?1.15–20.53%). There was no significant difference in the period of non-emergence of bloody stool and the period of non-recurrence of UC between the two groups (P > 0.05). The incidences of adverse events were 48.78% (60/123) and 48.00% (60/125) in the MR and EC groups, respectively (P = 0.902). The incidences of adverse drug reactions were 16.26% (20/123) and 13.60% (17/125) in the MR and EC groups, respectively (P = 0.556).Conclusion
Mesalazine modified-release tablets were non-inferior to the enteric-coated tablets and may be considered an effective and safe treatment alternative for the maintenance of remission in Chinese patients with UC.Trial registration

Introduction
Comparative data on the burden of atopic dermatitis (AD) in adults relative to the general population are limited. We performed a large-scale evaluation of the burden of disease among US adults with AD relative to matched non-AD controls, encompassing comorbidities, healthcare resource utilization (HCRU), and costs, using healthcare claims data. The impact of AD disease severity on these outcomes was also evaluated.Methods
Adult AD patients in the Commercial (n = 83,106), Medicare (n = 31,060), and Medi-Cal (n = 5550) databases were matched (1:1) to non-AD controls by demographic characteristics. AD patients were stratified by disease severity (higher, lower) using treatment as a surrogate measure of severity. The comorbidity burden, HCRU, and costs were evaluated during a 12-month follow-up period.Results
In the Commercial, Medicare, and Medi-Cal populations, patients with AD had a significantly higher overall comorbidity burden (P < 0.0001), an increased risk of asthma and allergic rhinitis (both P < 0.0001), higher HCRU (P < 0.05), and higher mean total per patient costs (Commercial: US$10,461 versus US$7187; Medicare: US$16,914 versus US$13,714; Medi-Cal; US$19,462 versus US$10,408; all P < 0.0001), compared with matched non-AD controls. Higher disease severity was associated with an increased comorbidity burden (P < 0.0001), HCRU (P < 0.05), and total costs (Commercial: US$14,580 versus US$7192; Medicare: US$21,779 versus US$12,490; Medi-Cal; US$22,123 versus US$16,639; all P < 0.0001) relative to lower severity disease.Conclusion
In this large-scale, healthcare claims database analysis, AD patients had a significantly higher comorbidity burden, HCRU, and costs compared with matched non-AD controls. Higher disease severity was associated with an even greater comorbidity and economic burden.Funding

Introduction
This study compared the efficacy and safety of two mesalazine formulations in the treatment of Chinese patients with mildly to moderately active ulcerative colitis (UC).Methods
In this multicenter, single-blind, randomized controlled study of 251 patients with active UC conducted from November 2010 to January 2012, subjects were randomized to treatment with mesalazine modified-release tablets (MR group, n = 123) or enteric-coated tablets (EC group, n = 128) at 800 mg three-times daily for 8 weeks. The primary efficacy measure was the decrease in UC Disease Activity Index (UCDAI) at final evaluation. If the 95% confidence interval (CI) lower limit of the difference of the decrease in UCDAI between groups was over ?1.0, mesalazine modified-release tablets were considered non-inferior to mesalazine enteric-coated tablets. The change in UCDAI in patients with mild and moderate (UCDAI 3–5 and 6–8 at enrollment, respectively) UC was analyzed. Secondary efficacy measures were remission and efficacy rates. Incidences of adverse drug reactions (ADRs) were calculated.Results
The decreases in UCDAI at final evaluation were 2.84 and 2.56 in the MR and EC groups, respectively, with a difference of 0.27 between groups (95% CI ?0.34, 0.88). The remission rates were 48.33% (58/120) and 55.65% (69/124), and the efficacy rates were 63.33% (76/120) and 66.94% (83/124) in the MR and EC groups, respectively (all P > 0.05). In patients with mild UC, the decreases in UCDAI were 2.16 and 2.05 in the MR and EC groups, respectively, while in patients with moderate UC they were 3.49 and 3.03, respectively (all P > 0.05). The incidences of ADRs in the MR and EC groups were 6.61% (8/121) and 10.24% (13/127), respectively (P > 0.05). No serious ADRs were reported during the study.Conclusion
Mesalazine modified-release tablets are non-inferior to enteric-coated tablets and are an effective and safe treatment option in Chinese patients with mildly to moderately active UC.Trial registration
