Abstract
In randomized clinical trials (RCTs) of nonvitamin K antagonist oral anticoagulants (NOACs) for acute venous thromboembolism (VTE), ~ 12-13% of patients were elderly and ~ 26% had mild-to-moderate renal impairment. Observational studies are not restricted by the selection and treatment criteria of RCTs. In this ancillary analysis of the RE-COVERY DVT/PE global observational study, we aimed to describe patient characteristics, comorbidities, and anticoagulant therapy for subgroups of age (< or ≥ 75 years) and renal impairment (creatinine clearance [CrCl; estimated with Cockcroft-Gault formula] < 30 [severe], 30 to < 50 [moderate], 50 to < 80 [mild], ≥ 80 [normal] mL/min). Of 6095 eligible patients, 25.3% were aged ≥ 75 years; 38.2% (1605/4203 with CrCl values) had mild-to-moderate renal impairment. Comorbidities were more common in older patients (73.9% aged ≥ 75 vs. 58.1% < 75 years) and in those with mild or moderate versus no renal impairment (75.9%, 80.9%, and 59.3%, respectively). At hospital discharge or 14 days after diagnosis (whichever was later), most patients (53.7% and 55.1%, respectively) in both age groups received NOACs; 20.8% and 23.4%, respectively, received vitamin K antagonists, 19.0% and 21.8% parenteral therapy, 2.3% and 3.8% other anticoagulant treatments. Use of NOACs decreased with worsening renal impairment (none 58.5%, moderate 49.6%, severe 25.7%) and, in younger versus older patients with moderate renal impairment (33.1% vs. 56.1%). In routine practice, there are more elderly and renally impaired patients with VTE than represented in RCTs. Decreasing renal function, but not older age, was associated with less NOAC use. Clinical Trial Registration: http://www.clinicaltrials.gov . Unique identifier: NCT02596230. Decreasing renal function, particularly in the subgroup with CrCl < 30 mL/min, but not older age, was associated with less use of nonvitamin K antagonist oral anticoagulants (NOACs). Nevertheless, more than half of the older patients with moderate renal impairment received a NOAC as their oral anticoagulant.

Abstract
IMPORTANCE Hypertension and carotid stenosis are both risk factors for stroke, but the presence of carotid stenosis might dampen enthusiasm for tight control of hypertension because of concerns for hypoperfusion. OBJECTIVE To determine the extent to which there are opportunities to potentially improve pharmacotherapy for hypertension in patients known to have asymptomatic high-grade carotid stenosis. DESIGN We examined anti-hypertensive medication prescription and adherence to evidence-based hypertension treatment guidelines in a cross-sectional analysis of baseline data of patients enrolled in a clinical trial. SETTING The Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis Trial (CREST-2) is a multicenter prospective randomized open blinded end-point clinical trial of intensive medical management with or without revascularization by endarterectomy or stenting for asymptomatic high-grade carotid stenosis. PARTICIPANTS 1479 participants (38.6% female; mean age 69.8 years) from 132 clinical centers enrolled in the CREST-2 trial as of April 6, 2020 who were taking ≥1 antihypertensive drug at baseline. EXPOSURES Pharmacotherapy for hypertension. MAIN OUTCOME Adherence to evidence-based guidelines for treating hypertension. RESULTS Of 1458 participants with complete data, 26% were on one, 31% on 2, and 43% on ≥3 antihypertensive medications at trial entry. Thirty-two percent of participants were prescribed thiazide; 74%, angiotensin converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB); 38%, calcium channel blocker (CCB); 56%, a beta blocker; 11%, loop diuretic; and 27%, other. Of those prescribed a single antihypertensive medication, the proportion prescribed thiazide was 5%; ACEI or ARB, 55%, and CCB, 11%. The prevalence of guideline-adherent regimens was 34% (95% CI, 31-36%). CONCLUSIONS AND RELEVANCE In a diverse cohort with severe carotid disease and hypertension, non-adherence to hypertension guidelines was common. All preferred classes of antihypertensive drug were under-prescribed. Using staged iterative guideline-based care for hypertension, CREST-2 will characterize drug tolerance and stroke rates under these conditions.

Abstract
Limited data are available regarding contemporary multiple myeloma (MM) treatment practices in Latin America. In this retrospective cohort study, medical records were reviewed for a multinational cohort of 1103 Latin American MM patients (median age, 61 years) diagnosed in 2008-2015 who initiated first-line therapy (LOT1). Of these patients, 33·9% underwent autologous stem cell transplantation (ASCT). During follow-up, 501 (45·4%) and 129 (11·7%) patients initiated second- (LOT2) and third-line therapy (LOT3), respectively. In the LOT1 setting, from 2008 to 2015, there was a decrease in the use of thalidomide-based therapy, from 66·7% to 42·6%, and chemotherapy from, 20·2% to 5·9%, whereas use of bortezomib-based therapy or bortezomib + thalidomide increased from 10·7% to 45·5%. Bortezomib-based therapy and bortezomib + thalidomide were more commonly used in ASCT patients and in private clinics. In non-ASCT and ASCT patients, median progression-free survival (PFS) was 15·0 and 31·1 months following LOT1 and 10·9 and 9·5 months following LOT2, respectively. PFS was generally longer in patients treated with bortezomib-based or thalidomide-based therapy versus chemotherapy. These data shed light on recent trends in the management of MM in Latin America. Slower uptake of newer therapies in public clinics and poor PFS among patients with relapsed MM point to areas of unmet therapeutic need in Latin America.

Abstract
PURPOSE During the alirocumab open-label extension study ODYSSEY OLE (open-label extension; NCT01954394), physicians could adjust alirocumab dosing for enrolled patients, who were diagnosed with heterozygous familial hypercholesterolemia (HeFH) and who had completed previous phase III clinical trials with alirocumab. This post hoc analysis evaluated the differences in physician-patient dosing decisions between the regions of Western Europe, Eastern Europe, North America, and the rest of the world (ROW). METHODS Patients (n = 909) who received starting dose alirocumab 75 mg every 2 weeks (Q2W) during ODYSSEY OLE (patients from FH I, FH II, and LONG TERM parent studies) were included. Low-density lipoprotein cholesterol (LDL-C) levels were blinded until week 8; subsequently, LDL-C values were communicated to physicians. From week 12, dose adjustment from 75 to 150 mg Q2W, or vice versa, was possible. RESULTS Mean LDL-C values used for the decision to increase dose from 75 to 150 mg Q2W were higher in Eastern Europe (3.7 mmol/L; 144.0 mg/dL) and ROW (3.8 mmol/L; 145.2 mg/dL) compared with Western Europe (3.1 mmol/L; 118.6 mg/dL) and North America (3.3 mmol/L; 126.6 mg/dL). Irrespective of region, the mean LDL-C at the time of decision to maintain at 75 mg Q2W was approximately 1.8 mmol/L (70 mg/dL). During ODYSSEY OLE (median treatment duration of 131.7 weeks), alirocumab was shown to have no unexpected long-term safety concerns. CONCLUSIONS In this OLE study, the observed variations in clinical treatment decisions suggest that physicians may perceive the severity of HeFH and/or the treatment of HeFH differently depending on their region.

Abstract
AIMS/INTRODUCTION Due to the paucity of tofogliflozin data, we assessed the safety and effectiveness of tofogliflozin among Japanese patients with type 2 diabetes mellitus in the clinical setting, stratifying the patients by age, sex, estimated glomerular filtration (eGFR) rate and body mass index. We report the results of a 12-month interim analysis. MATERIALS AND METHODS This was a 3-year prospective, observational and multicenter post-marketing study (Japanese Study of tofogliflozin with type 2 diabetes mellitus Patients/Long Term). RESULTS Out of 6,897 patients enrolled, the safety and effectiveness analysis populations consisted of 6,712 and 6,449 patients, respectively. During 12 months, adverse drug reactions and their incidence were 9.12 and 0.88%, respectively. The incidence of hypoglycemia was 0.67%. Polyuria/pollakiuria occurred more frequently in patients aged ≥65 years than in patients aged <65 years. Women experienced higher rates of urinary tract and genital infection than men. The lowest eGFR subgroup experienced maximum volume depletion-related events. Cardiovascular and cerebrovascular disorders occurred in 0.55% of the patients. Glycated hemoglobin (HbA1c) and bodyweight significantly decreased by -0.76% and -2.73 kg, respectively, from baseline to the last observation carried forward (P < 0.0001). Except for the lowest eGFR subgroup, other eGFR subgroups showed significantly decreased HbA1c values. All eGFR subgroups showed significantly decreased bodyweight, and all body mass index subgroups showed significantly decreased HbA1c and bodyweight. CONCLUSIONS Our interim 12-month data suggest that tofogliflozin could be used safely and effectively in Japanese patients with type 2 diabetes mellitus, as tofogliflozin was well tolerated with low hypoglycemia risk, and significantly improved HbA1c and bodyweight.

Abstract
AIMS/INTRODUCTION The present study analysis was carried out to evaluate the safety and efficacy of tofogliflozin, a sodium-glucose cotransporter 2 inhibitor, in Japanese patients with type 2 diabetes mellitus in real-world clinical practice. MATERIALS AND METHODS This was a 3-year non-interventional observational study of patients with type 2 diabetes mellitus newly administered tofogliflozin who were uncontrolled on current therapy. We carried out a 12-week interim analysis of tofogliflozin as part of 3-year post-marketing surveillance study. The incidence of adverse drug reactions was evaluated as a safety end-point. As efficacy end-points, glycated hemoglobin and bodyweight were evaluated. RESULTS A total of 6,897 patients were enrolled. Tofogliflozin significantly reduced mean changes from baseline glycated hemoglobin (-0.63%, P < 0.0001) and bodyweight (-2.02 kg, P < 0.0001). The change in glycated hemoglobin and bodyweight reductions in response to tofogliflozin was consistently observed in all body mass index subgroups. Adverse drug reactions occurred in 345 of 6,712 patients (5.14%). There was a low incidence of adverse drug reactions known to be associated with sodium-glucose cotransporter 2 inhibitors, and they were reported as non-serious. The incidences of polyuria/pollakiuria were higher in patients aged ≥65 years than <65 years, and were significantly different among estimated glomerular filtration rate subgroups. Urinary tract and genital infections occurred more frequently in women than in men. CONCLUSIONS Tofogliflozin was well tolerated, and no emerging new safety concerns were observed. Tofogliflozin significantly improved glycemic control with no impact on bodyweight gain. The short-term administration of tofogliflozin is considered to have a favorable benefit-risk profile in Japanese patients with type 2 diabetes mellitus.

Abstract
BACKGROUND Although cholesterol-lowering medications can reduce the risk of recurrent cardiovascular events, premature discontinuation limits effectiveness. Discontinuation rates have not been systematically reported for lipid-lowering trials. METHODS AND RESULTS We evaluated medication discontinuation in IMPROVE-IT (Improved Reduction of Outcomes: Vytorin Efficacy International Trial), which evaluated placebo+simvastatin versus ezetimibe+simvastatin in patients hospitalized with the acute coronary syndrome and followed longitudinally postdischarge. Reasons for discontinuation were evaluated from randomization through study end (median 71.9 [interquartile range 51.8-85.8] months). Kaplan-Meier (KM) discontinuation rates were evaluated at 30 days, 1 year, and through year 7, and compared by treatment arm and region, with Cox proportional hazards modeling used to evaluate predictors of discontinuation. Overall, 46.7% of subjects discontinued study medication (KM rate by study end 50.9% [95% CI, 50.1%-51.7%]). The risk of discontinuation was highest early in the trial but decreased with increasing time, with a terminal KM rate per 100 person-years of 8.4 (8.2-8.6) from years 1 to 7. Discontinuation was higher in the placebo+simvastatin versus ezetimibe+simvastatin arm (KM rate 52.0% versus 49.8%, P=0.049) and was highest in the United States (7-year KM rate 57.4%). In multivariable modeling, smoking, prior revascularization, hypertension, unstable angina, female sex, nonwhite race, and US location were associated with higher discontinuation rates. CONCLUSIONS Although discontinuation was highest early and stabilized to 8% per year, because of prolonged follow-up, most discontinuation occurred after year 1. Adding ezetimibe to statin therapy did not increase discontinuation risk. Geographic differences and patient-level factors should be considered in trial design and analysis.

Abstract
BACKGROUND Non-vitamin K antagonist oral anticoagulants (NOACs), including apixaban, are recommended for prevention of stroke and systemic embolism in non-valvular atrial fibrillation (NVAF). AIMS To describe the characteristics of patients starting anticoagulant treatment, identify the characteristics associated with apixaban prescription, and describe apixaban use in France. METHODS This was a non-interventional multicentre French study. Patients with NVAF (aged≥18 years) with anticoagulant treatment started in the preceding 3 months were evaluated in four groups (NOAC [apixaban, dabigatran or rivaroxaban] or vitamin K antagonist [VKA]). RESULTS Data from 2027 patients were eligible for analysis. Mean age was 73.0±11.2 years, 56.6% were men and 80.2% were anticoagulant naïve. Stage≥4 chronic kidney disease was present in 2.2% of patients prescribed apixaban, none of those prescribed dabigatran or rivaroxaban, and 16.8% of those prescribed VKAs. The median CHA2DS2-VASc score was 3 for all three NOACs and 4 for VKAs; the median HAS-BLED score was≥3 for 2.5-5.9% of patients prescribed NOACs and 12.0% of those prescribed VKAs. Apixaban was more likely to be prescribed than other NOACs in older patients with higher bleeding risk and decreased renal function, and VKAs in patients with lower bleeding risk and better renal function. Patients received a reduced dose (5mg/day; 30.4% patients) or a full dose (10mg/day; 69.6% patients) of apixaban. Only 79.3% of patients prescribed apixaban had doses consistent with the summary of product characteristics; underdosing was more frequent than overdosing. Off-label use of apixaban was observed, mainly in elderly patients, despite normal renal function and weight. CONCLUSIONS Initiation of apixaban versus NOACs was more common among patients with increased age, higher bleeding risk and decreased renal function, whereas initiation of apixaban versus VKAs was more common among patients with lower bleeding risk and better renal function.

Abstract
OBJECTIVES Gout management includes non-pharmacological measures (NPM). The main objective of this study was to describe the NPM proposed by physicians and their implementation by patients after 3-6 months. The secondary objective was to identify NPM compliance profiles among these patients. METHODS Ancillary observational study using the GOSPEL French cohort of 1003 patients with gout, based on questionnaires for physicians and patients at inclusion and then after 3-6 months. Patients were included by a representative sample of 398 general practitioners (GP) and 109 private-practice rheumatologists. Modifiable risk factors of hyperuricemia and proposed NPM were compared. Patient compliance profiles were identified by multiple correspondence and hierarchical clustering analysis. RESULTS The study included 630 patients: 80.7% were obese or overweight, 51% reported excessive alcohol consumption. Physicians identified fewer modifiable risk factors than their real prevalence in the cohort. Physicians proposed NPM to 57% of patients, particularly diet modifications (46.4%). Increasing physical activity (P < 0.0001) was the best followed NPM. The physician's influence in the decision of starting NPM was more frequent among GPs' patients (P = 0.01). Three patients' compliance profiles were identified. "Very good responders" (55.8%) implemented all the proposed NPM. "Good responders" (12.7%) had a more severe disease and followed the proposed NPM, but for alcohol consumption. "Bad responders" (31.5%) did not modify their life style: these were older patients with a very recent gout diagnosis. CONCLUSION More personalized care about NPM requires adapting the practitioner's approach to patients' compliance profiles, especially elderly patients with recent gout.

Abstract
BACKGROUND Non-vitamin K antagonist oral anticoagulants (NOACs) are indicated for stroke prevention in atrial fibrillation (AF) but require lower doses in certain patients. We sought to describe the frequency, appropriateness (according to Food and Drug Administration labeling), and outcomes of patients prescribed reduced doses of NOACs in community practice. METHODS AND RESULTS We analyzed data from the ORBIT-AF II (The Outcomes Registry for Better Informed Treatment of Atrial Fibrillation II) registry, a prospective, national, observational registry of AF patients. Among 7925 AF patients receiving NOACs, we assessed patterns of use of reduced NOAC doses and associated cardiovascular and bleeding outcomes at median follow-up of 1 year. Overall, 6636 patients (84%) received a NOAC at standard dose, which was consistent with US Food and Drug Administration labeling in 6376 (96%). Reduced NOAC dose was prescribed to 1289 (16% overall), which was consistent with Food and Drug Administration labeling in only 555 patients (43%). Compared with those whose NOAC dose was appropriately reduced, patients receiving inappropriate dose reductions were younger (median age 79 versus 84, P<0.0001) and had lower ORBIT bleeding risk scores (26% ≥4 versus 45%, P<0.0001). Compared with those appropriately receiving standard dosing, patients receiving inappropriately reduced-dose NOACs had higher unadjusted rates of thromboembolic events (2.11 versus 1.35 events per 100 patient years, hazard ratio 1.56, 95% confidence interval 0.92-2.67) and death (6.77 versus 2.60, hazard ratio 2.61, 95% confidence interval 1.86-3.67). After adjustment, outcomes were not significantly different but tended to favor patients dosed appropriately. CONCLUSIONS The majority of dose reductions of NOACs in AF are inconsistent with US Food and Drug Administration recommendations. There appear to be opportunities to improve current NOAC dosing in community practice. CLINICAL TRIAL REGISTRATION URL: http://www.clinicaltrials.gov. Unique identifier: NCT01701817.
