RESUMO
BACKGROUND: Patients with heart failure with preserved ejection fraction have significant impairment in health-related quality of life. In the EMPEROR-Preserved trial (Empagliflozin Outcome Trial in Patients With Chronic Heart Failure With Preserved Ejection Fraction), we evaluated the efficacy of empagliflozin on health-related quality of life in patients with heart failure with preserved ejection fraction and whether the clinical benefit observed with empagliflozin varies according to baseline health status. METHODS: Health-related quality of life was measured with the Kansas City Cardiomyopathy Questionnaire (KCCQ) at baseline and 12, 32, and 52 weeks. Patients were divided by baseline KCCQ Clinical Summary Score (CSS) tertiles, and the effect of empagliflozin on outcomes was examined. The effect of empagliflozin on KCCQ-CSS, Total Symptom Score, and Overall Summary Score was evaluated. Responder analyses were performed to compare the odds of improvement and deterioration in KCCQ related to treatment with empagliflozin. RESULTS: The effect of empagliflozin on reducing the risk of time to cardiovascular death or heart failure hospitalization was consistent across baseline KCCQ-CSS tertiles (hazard ratio, 0.83 [95% CI, 0.69-1.00], 0.70 [95% CI, 0.55-0.88], and 0.82 [95% CI, 0.62-1.08] for scores <62.5, 62.5-83.3, and ≥83.3, respectively; P trend=0.77). Similar results were seen for total heart failure hospitalizations. Patients treated with empagliflozin had significant improvement in KCCQ-CSS versus placebo (+1.03, +1.24, and +1.50 at 12, 32, and 52 weeks, respectively; P<0.01); similar results were seen for Total Symptom Score and Overall Summary Score. At 12 weeks, patients on empagliflozin had higher odds of improvement ≥5 points (odds ratio, 1.23 [95% CI, 1.10-1.37]), ≥10 points (odds ratio, 1.15 [95% CI, 1.03-1.27]), and ≥15 points (odds ratio, 1.13 [95% CI, 1.02-1.26]) and lower odds of deterioration ≥5 points in KCCQ-CSS (odds ratio, 0.85 [95% CI, 0.75-0.97]). A similar pattern was seen at 32 and 52 weeks, and results were consistent for Total Symptom Score and Overall Summary Score. CONCLUSIONS: In patients with heart failure with preserved ejection fraction, empagliflozin reduced the risk for major heart failure outcomes across the range of baseline KCCQ scores. Empagliflozin improved health-related quality of life, an effect that appeared early and was sustained for at least 1 year.

BACKGROUND: The presence of ischemic heart disease impacts prognosis in patients affected by heart failure and reduced ejection fraction (HFrEF). It is not well known how the extent of vascular disease impacts prognoses and responses to therapy in this setting. METHODS: In this post hoc analysis of the EMPEROR-Reduced trial, outcomes and the effects of empagliflozin, were assessed in study participants according to the extent (none vs mono1 vs poly [≥ 2] vascular bed) of vascular disease. Vascular disease was defined as investigator-reported coronary artery disease (CAD), peripheral artery disease (PAD) and cerebrovascular disease at baseline. Cox proportional-hazards models were used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs). Incidence rates are presented per 100 person-years (py) of follow-up. RESULTS: Of the 3730 study participants enrolled, 1324 (35.5%) had no vascular disease, 1879 (50.4%) had monovascular disease, and 527 (14.1%) had polyvascular disease. Participants with polyvascular disease tended to be older and male and to have had histories of hypertension, diabetes and smoking. In the placebo arm, a significantly higher risk for cardiovascular death existed in those with polyvascular disease (HR 1.57, 95% CI1.02, 2.44, compared to those with no vascular disease). In adjusted analysis, the benefit of empagliflozin in cardiovascular death or hospitalization due to HF, HF hospitalization, cardiovascular death, renal composite endpoint, estimated glomerular filtration slope changes, and health status scores were seen across the 3 groups (interaction P > 0.05 for all) but were attenuated in those with polyvascular disease. Adverse events were higher in those with polyvascular disease, but no major differences were noted between empagliflozin or placebo assignment in the 3 groups. CONCLUSION: In patients with HFrEF, the extent of vascular disease is associated with the risk for adverse cardiovascular outcomes. Empagliflozin offers cardiovascular and renal benefits in HFrEF across the extent of vascular disease, but this benefit is attenuated in those with polyvascular disease.
RESUMO
AIMS: To study the oral 11 beta-hydroxysteroid dehydrogenase-1 (11ß-HSD1) inhibitor BI 187004 (NCT02150824), as monotherapy and in combination with metformin, versus placebo in patients with type 2 diabetes mellitus (T2DM) affected by overweight or obesity. MATERIALS AND METHODS: This Phase II, randomized controlled trial investigated multiple rising doses of BI 187004 as monotherapy (Arm 1: 20, 80 or 240 mg) and in combination with metformin (Arm 2: 240 mg), in adults with T2DM and a body mass index of 28-40 kg/m2 . RESULTS: In total, 103 patients (Arm 1: n = 62, Arm 2: n = 41) were included in this study. BI 187004 was rapidly absorbed and exposure increased approximately dose-dependently. Target engagement of 11ß-HSD1 was observed with near-full inhibition of 11ß-HSD1 in the liver [decreased (5α-tetrahydrocortisol + 5ß-tetrahydrocortisol)/tetrahydrocortisone ratio]; hypothalamic-pituitary-adrenal axis activation was also seen (increased total urinary corticosteroids). No clinically relevant changes from baseline with BI 187004 treatment were observed for bodyweight or meal tolerance test parameters, or in most efficacy endpoints testing glucose and lipid metabolism; a significant increase was observed in weighted mean plasma glucose (p < .05 for 80 and 240 mg BI 187004) but not fasting plasma glucose. Drug-related adverse events were reported for 14 patients (22.6%) in Arm 1 and 10 patients (24.4%) in Arm 2, most frequently headache, diarrhoea, flushing and dizziness. A dose-dependent increase in heart rate was seen with BI 187004 treatment. CONCLUSIONS: BI 187004 was generally well tolerated in patients with T2DM. Despite complete 11ß-HSD1 inhibition, no clinically relevant effects were observed with BI 187004.

AIMS: In this secondary analysis of the EMPEROR-Reduced trial, we sought to evaluate whether the benefits of empagliflozin varied by baseline health status and how empagliflozin impacted patient-reported outcomes in patients with heart failure with reduced ejection fraction. METHODS AND RESULTS: Health status was assessed by the Kansas City Cardiomyopathy Questionnaires-clinical summary score (KCCQ-CSS). The influence of baseline KCCQ-CSS (analyzed by tertiles) on the effect of empagliflozin on major outcomes was examined using Cox proportional hazards models. Responder analyses were performed to assess the odds of improvement and deterioration in KCCQ scores related to treatment with empagliflozin. Empagliflozin reduced the primary outcome of cardiovascular death or heart failure hospitalization regardless of baseline KCCQ-CSS tertiles [hazard ratio (HR) 0.83 (0.68-1.02), HR 0.74 (0.58-0.94), and HR 0.61 (0.46-0.82) for <62.5, 62.6-85.4, and ≥85.4 score tertiles, respectively; P-trend = 0.10]. Empagliflozin improved KCCQ-CSS, total symptom score, and overall summary score at 3, 8, and 12 months. More patients on empagliflozin had ≥5-point [odds ratio (OR) 1.20 (1.05-1.37)], 10-point [OR 1.26 (1.10-1.44)], and 15-point [OR 1.29 (1.12-1.48)] improvement and fewer had ≥5-point [OR 0.75 (0.64-0.87)] deterioration in KCCQ-CSS at 3 months. These benefits were sustained at 8 and 12 months and were similar for other KCCQ domains. CONCLUSION: Empagliflozin improved cardiovascular death or heart failure hospitalization risk across the range of baseline health status. Empagliflozin improved health status across various domains, and this benefit was sustained during long-term follow-up. CLINICAL TRIAL REGISTRATION: URL: https://www.clinicaltrials.gov.

AIMS: The EMPERIAL (Effect of EMPagliflozin on ExeRcise ability and HF symptoms In patients with chronic heArt faiLure) trials evaluated the effects of empagliflozin on exercise ability and patient-reported outcomes in heart failure (HF) with reduced and preserved ejection fraction (EF), with and without type 2 diabetes (T2D), reporting, for the first time, the effects of sodium-glucose co-transporter-2 inhibition in HF with preserved EF (HFpEF). METHODS AND RESULTS: HF patients with reduced EF (HFrEF) (≤40%, N = 312, EMPERIAL-Reduced) or preserved EF (>40%, N = 315, EMPERIAL-Preserved), with and without T2D, were randomized to empagliflozin 10 mg or placebo for 12 weeks. The primary endpoint was 6-minute walk test distance (6MWTD) change to Week 12. Key secondary endpoints included Kansas City Cardiomyopathy Questionnaire Total Symptom Score (KCCQ-TSS) and Chronic Heart Failure Questionnaire Self-Administered Standardized format (CHQ-SAS) dyspnoea score. 6MWTD median (95% confidence interval) differences, empagliflozin vs. placebo, at Week 12 were -4.0 m (-16.0, 6.0; P = 0.42) and 4.0 m (-5.0, 13.0; P = 0.37) in EMPERIAL-Reduced and EMPERIAL-Preserved, respectively. As the primary endpoint was non-significant, all secondary endpoints were considered exploratory. Changes in KCCQ-TSS and CHQ-SAS dyspnoea score were non-significant. Improvements with empagliflozin in exploratory pre-specified analyses of KCCQ-TSS responder rates, congestion score, and diuretic use in EMPERIAL-Reduced are hypothesis generating. Empagliflozin adverse events were consistent with those previously reported. CONCLUSION: The primary outcome for both trials was neutral. Empagliflozin was well tolerated in HF patients, with and without T2D, with a safety profile consistent with that previously reported in T2D. Hypothesis-generating improvements in exploratory analyses of secondary endpoints with empagliflozin in HFrEF were observed.

Latin Americans are highly heterogeneous regarding the type of Native American ancestry. Consideration of specific associations with common diseases may lead to substantial advances in unraveling of disease etiology and disease prevention. Here we investigate possible associations between the type of Native American ancestry and leading causes of death. After an aggregate-data study based on genome-wide genotype data from 1805 admixed Chileans and 639,789 deaths, we validate an identified association with gallbladder cancer relying on individual data from 64 gallbladder cancer patients, with and without a family history, and 170 healthy controls. Native American proportions were markedly underestimated when the two main types of Native American ancestry in Chile, originated from the Mapuche and Aymara indigenous peoples, were combined together. Consideration of the type of Native American ancestry was crucial to identify disease associations. Native American ancestry showed no association with gallbladder cancer mortality (P = 0.26). By contrast, each 1% increase in the Mapuche proportion represented a 3.7% increased mortality risk by gallbladder cancer (95%CI 3.1-4.3%, P = 6×10-27). Individual-data results and extensive sensitivity analyses confirmed the association between Mapuche ancestry and gallbladder cancer. Increasing Mapuche proportions were also associated with an increased mortality due to asthma and, interestingly, with a decreased mortality by diabetes. The mortality due to skin, bladder, larynx, bronchus and lung cancers increased with increasing Aymara proportions. Described methods should be considered in future studies on human population genetics and human health. Complementary individual-based studies are needed to apportion the genetic and non-genetic components of associations identified relying on aggregate-data.

The addition of sequence data from own-study individuals to genotypes from external data repositories, for example, the HapMap, has been shown to improve the accuracy of imputed genotypes. Early approaches for reference panel selection favored individuals who best reflect recombination patterns in the study population. By contrast, a maximization of genetic diversity in the reference panel has been recently proposed. We investigate here a novel strategy to select individuals for sequencing that relies on the characterization of the ancestral kernel of the study population. The simulated study scenarios consisted of several combinations of subpopulations from HapMap. HapMap individuals who did not belong to the study population constituted an external reference panel which was complemented with the sequences of study individuals selected according to different strategies. In addition to a random choice, individuals with the largest statistical depth according to the first genetic principal components were selected. In all simulated scenarios the integration of sequences from own-study individuals increased imputation accuracy. The selection of individuals based on the statistical depth resulted in the highest imputation accuracy for European and Asian study scenarios, whereas random selection performed best for an African-study scenario. Present findings indicate that there is no universal 'best strategy' to select individuals for sequencing. We propose to use the methodology described in the manuscript to assess the advantage of focusing on the ancestral kernel under own study characteristics (study size, genetic diversity, availability and properties of external reference panels, frequency of imputed variants ).

AIM: Numerous genes are known to cause dilated cardiomyopathy (DCM). However, until now technological limitations have hindered elucidation of the contribution of all clinically relevant disease genes to DCM phenotypes in larger cohorts. We now utilized next-generation sequencing to overcome these limitations and screened all DCM disease genes in a large cohort. METHODS AND RESULTS: In this multi-centre, multi-national study, we have enrolled 639 patients with sporadic or familial DCM. To all samples, we applied a standardized protocol for ultra-high coverage next-generation sequencing of 84 genes, leading to 99.1% coverage of the target region with at least 50-fold and a mean read depth of 2415. In this well characterized cohort, we find the highest number of known cardiomyopathy mutations in plakophilin-2, myosin-binding protein C-3, and desmoplakin. When we include yet unknown but predicted disease variants, we find titin, plakophilin-2, myosin-binding protein-C 3, desmoplakin, ryanodine receptor 2, desmocollin-2, desmoglein-2, and SCN5A variants among the most commonly mutated genes. The overlap between DCM, hypertrophic cardiomyopathy (HCM), and channelopathy causing mutations is considerably high. Of note, we find that >38% of patients have compound or combined mutations and 12.8% have three or even more mutations. When comparing patients recruited in the eight participating European countries we find remarkably little differences in mutation frequencies and affected genes. CONCLUSION: This is to our knowledge, the first study that comprehensively investigated the genetics of DCM in a large-scale cohort and across a broad gene panel of the known DCM genes. Our results underline the high analytical quality and feasibility of Next-Generation Sequencing in clinical genetic diagnostics and provide a sound database of the genetic causes of DCM.

AIMS: Dilated cardiomyopathy (DCM) is one of the leading causes for cardiac transplantations and accounts for up to one-third of all heart failure cases. Since extrinsic and monogenic causes explain only a fraction of all cases, common genetic variants are suspected to contribute to the pathogenesis of DCM, its age of onset, and clinical progression. By a large-scale case-control genome-wide association study we aimed here to identify novel genetic risk loci for DCM. METHODS AND RESULTS: Applying a three-staged study design, we analysed more than 4100 DCM cases and 7600 controls. We identified and successfully replicated multiple single nucleotide polymorphism on chromosome 6p21. In the combined analysis, the most significant association signal was obtained for rs9262636 (P = 4.90 × 10(-9)) located in HCG22, which could again be replicated in an independent cohort. Taking advantage of expression quantitative trait loci (eQTL) as molecular phenotypes, we identified rs9262636 as an eQTL for several closely located genes encoding class I and class II major histocompatibility complex heavy chain receptors. CONCLUSION: The present study reveals a novel genetic susceptibility locus that clearly underlines the role of genetically driven, inflammatory processes in the pathogenesis of idiopathic DCM.

AIMS: Baseline body mass index (BMI) and weight loss promoted by sodium-glucose cotransporter 2 inhibitors may impact outcomes in patients with heart failure with reduced ejection fraction (HFrEF). We assessed in the EMPEROR-Reduced population treated with empagliflozin versus placebo the relationship between baseline BMI, weight loss and effects on the primary (time to first hospitalization for heart failure [HHF] or cardiovascular death) and key secondary outcomes. METHODS AND RESULTS: We categorized patients according to their baseline BMI: <20 kg/m2 (n = 180); 20 to <25 kg/m2 (n = 1038); 25 to <30 kg/m2 (n = 1345); 30 to <35 kg/m2 (n = 774) and ≥35 kg/m2 (n = 393). The treatment effect of empagliflozin on the primary outcome was consistent across all BMI categories (hazard ratios in subgroups 0.66-0.88, interaction trend p = 0.32), as was the effect on total (first plus recurrent) HHF (interaction trend p = 0.31). Empagliflozin reduced the rate of estimated glomerular filtration rate decline consistently across the BMI categories (interaction trend p = 0.67). Overall, incidence rates of any or serious adverse events were comparable between the treatment groups across all BMI categories. A total of 313 (17.4%) patients treated with empagliflozin experienced a weight loss of more than 5% at week 52 versus 230 (12.8%) in placebo. When analysed separately within each treatment group, presence of weight loss was similarly associated with an increased risk of all-cause mortality. CONCLUSION: The benefits of empagliflozin versus placebo were consistently present across all BMI categories in HFrEF patients. Weight loss was associated with higher risk of all-cause mortality, regardless of treatment group.

AIM: To quantify and compare the responsiveness within the meaning of clinical relevance of efficacy endpoints in a clinical trial with over the counter (OTC) analgesics for headache. Efficacy endpoints and observed differences in clinical trials need to be clinically meaningful and mirror the change in the clinical status of a patient. This must be demonstrated for the specific disease indication and the particular patient population based on the application of treatments with proven efficacy. METHODS: Patient's global efficacy assessment during two study phases (pre-phase and treatment phase) was used to classify patients as satisfied or non-satisfied with the efficacy of their medication. The analysis is based on 1734 patients included in the efficacy analysis of a randomized, placebo-controlled, double-blind, multi-centre parallel group trial with six treatment arms. Based on this classification and the pain intensity recorded by the patients on a 100 mm visual analogue scale, group differences by assessment categories and receiver operating characteristic (ROC) curve methods were used to quantify responsiveness of the efficacy endpoints 'time to 50% pain relief', 'time until reduction of pain intensity to 10 mm', 'weighted sum of pain intensity difference' (%SPIDweighted), 'pain intensity difference (PID) relative to baseline at 2 hours', and 'pain-free at 2 hours'. RESULTS: Clinically relevant differences between patients satisfied and non-satisfied with the treatment were observed for all efficacy endpoints. Patients with the highest rating of efficacy had the fastest and strongest pain relief. In comparison, patients assessing efficacy as 'less good' reached a 50% pain relief on average nearly an hour later than those scoring efficacy as at least 'good'. Simultaneously, their extent of pain relief was only half as great 2 hours after medication intake. Patients scoring efficacy as 'poor' experienced practically no pain relief within the 4 hour observation interval. ROC curve calculations confirmed an adequate responsiveness for all continuous endpoints. The following cut-off points for differentiating between satisfied and non-satisfied patients were deduced from the data in the pre- and treatment phase, respectively: 'time to 50% pain relief' 1:10 and 1:31 h:min, 'time until reduction of pain intensity to 10 mm' 2:40 and 3:00 h:min, '%SPIDweighted' 68 and 64%, 'PID at 2 hours' 35 and 35 mm. The sensitivity and specificity based on these cut-off points ranged from 70 to 79%. The binary endpoint 'pain-free at 2 hours' showed a clearly higher specificity (80 and 87%) than sensitivity (65 and 61%) in the pre- and treatment phase, respectively. CONCLUSIONS: When global assessment of efficacy by the patient was used as external criterion, ROC curve calculations confirmed a high responsiveness for all efficacy endpoints included in this study. Clinically relevant differences between patients satisfied and non-satisfied with the treatment were observed. The endpoint '%SPIDweighted' proved slightly but consistently superior to the other endpoints. SPID and %SPIDweighted are not easy to interpret and the time course of pain reduction is of high importance for the patients in the treatment of acute pain, including headache. The endpoint 'pain-free at 2 hours' showed the expected high specificity, but at the cost of a concurrently low sensitivity and clearly makes less use of the available information than the endpoint 'time to 50% pain reduction', which combines the highly relevant aspects of time course and extent of pain reduction. Responsiveness, the ability of an outcome measure to detect clinically important changes in a specific condition of a patient, should be added in future revisions of IHS guidelines for clinical trials in headache disorders.

BACKGROUND: Differences in clinically important thresholds in patient-reported outcomes measures such as the Kansas City Cardiomyopathy Questionnaire (KCCQ) remain less well-established in patients with heart failure with preserved ejection fraction (HFpEF) versus heart failure with reduced ejection fraction (HFrEF). OBJECTIVES: The purpose of this study was to estimate meaningful thresholds for improvement or deterioration in the KCCQ-Total Symptom Score (TSS) in patients with HFrEF versus HFpEF. METHODS: This secondary analysis of EMPERIAL program used anchor- and distribution-based approaches to estimate thresholds for improvement or deterioration in the KCCQ-TSS using Patient Global Impression of Severity (PGIS) as the primary anchor. Mean change in KCCQ-TSS from baseline to week 12 was calculated for each PGIS. RESULTS: A total of 312 HFrEF and 315 HFpEF patients were enrolled. At week 12, mean changes in KCCQ-TSS corresponding to PGIS changes of "any improvement," "1-category improvement," and "1-category deterioration" were 13 ± 17, 12 ± 17, -3 ± 16 points in HFrEF, and 15 ± 18, 13 ± 17, -7 ± 18 points in HFpEF. Threshold for meaningful within-patient change in KCCQ-TSS was ≥9 points in HFrEF and ≥7 points in HFpEF patients. Sensitivity and specificity of ≥9 points/≥7 points change was 0.65 and 0.70 for HFrEF and 0.64 and 0.66 for HFpEF. Cumulative distribution function curves of KCCQ-TSS change from baseline to week 12 showed a shift to higher scores in both HFrEF and HFpEF patients. CONCLUSIONS: In the EMPERIAL program, a change in KCCQ-TSS of ≥9 points in HFrEF and ≥7 points in HFpEF represents the minimal clinically important difference for improvement, confirming the broad range of 5-10 points as meaningful thresholds.

BACKGROUND: It is important to evaluate whether a new treatment for heart failure with reduced ejection fraction (HFrEF) provides additive benefit to background foundational treatments. As such, we aimed to evaluate the efficacy and safety of empagliflozin in patients with HFrEF in addition to baseline treatment with specific doses and combinations of disease-modifying therapies. METHODS: We performed a post-hoc analysis of the EMPEROR-Reduced randomised, double-blind, parallel-group trial, which took place in 520 centres (hospitals and medical clinics) in 20 countries in Asia, Australia, Europe, North America, and South America. Patients with New York Heart Association (NYHA) classification II-IV with an ejection fraction of 40% or less were randomly assigned (1:1) to receive the addition of either oral empagliflozin 10 mg per day or placebo to background therapy. The primary composite outcome was cardiovascular death and heart failure hospitalisation; the secondary outcome was total heart failure hospital admissions. An extended composite outcome consisted of inpatient and outpatient HFrEF events was also evaluated. Outcomes were analysed according to background use of angiotensin-converting enzyme (ACE) inhibitors, angiotensin II receptor blockers (ARBs) or angiotensin receptor neprilysin inhibitors (ARNIs), as well as ß blockers and mineralocorticoid receptor antagonists (MRAs) at less than 50% or 50% or more of target doses and in various combinations. This study is registered with ClinicalTrials.gov, NCT03057977. FINDINGS: In this post-hoc analysis of 3730 patients (mean age 66·8 years [SD 11·0], 893 [23·9%] women; 1863 [49·9%] in the empagliflozin group, 1867 [50·1%] in the placebo group) assessed between March 6, 2017, and May 28, 2020, empagliflozin reduced the risk of the primary outcome (361 in 1863 participants in the empagliflozin group and 462 of 1867 in the placebo group; HR 0·75 [95% CI 0·65-0·86]) regardless of background therapy or its target doses for ACE inhibitors or ARBs at doses of less than 50% of the target dose (HR 0·85 [0·69-1·06]) and for doses of 50% or more of the target dose (HR 0·67 [0·52-0·88]; pinteraction=0·18). A similar result was seen for ß blockers at doses of less than 50% of the target dose (HR 0·66 [0·54-0·80]) and for doses of 50% or more of the target dose (HR 0·81 [0·66-1·00]; pinteraction=0·15). Empagliflozin also reduced the risk of the primary outcome irrespective of background use of triple therapy with an ACE inhibitor, ARB, or ARNI plus ß blocker plus MRA (given combination HR 0·73 [0·61-0·88]; not given combination HR 0·76 [0·62-0·94]; pinteraction=0·77). Similar patterns of benefit were observed for the secondary and extended composite outcomes. Empagliflozin was well tolerated and rates of hypotension, symptomatic hypotension, and hyperkalaemia were similar across all subgroups. INTERPRETATION: Empagliflozin reduced serious heart failure outcomes across doses and combinations of disease-modifying therapies for HFrEF. Clinically, these data suggest that empagliflozin might be considered as a foundational therapy in patients with HFrEF regardless of their existing background therapy.

INTRODUCTION: Back and neck pain are common musculoskeletal disorders. Topical non-steroidal anti-inflammatory drugs (NSAIDs) are frequently used to reduce pain and inflammation with fewer systemic side effects and drug interactions compared with oral NSAIDs. This study assessed efficacy and tolerability of a topical combination of capsaicin + diclofenac to treat acute back/neck pain. METHODS: In a randomized, double-blind, controlled, multicenter, parallel group trial, 746 patients were treated twice-daily for 5 days with diclofenac 2% + capsaicin 0.075%, diclofenac 2%, capsaicin 0.075% or placebo. Efficacy assessments included change and area under the curve in pain on movement for the worst procedure (POMWP), change in pressure algometry, and number of patients with decrease in POMWP of ≥ 30% and ≥ 50%. Adverse events (AEs) were recorded. RESULTS: Change in POMWP between baseline and day 2 evening, 1 h after drug application, demonstrates superiority of the combination (- 3.05 cm) versus diclofenac alone (- 2.33 cm) and placebo (- 2.45 cm), but not capsaicin alone (- 3.26 cm). AEs were consistent with known safety profiles. CONCLUSION: Capsaicin alone and capsaicin + diclofenac showed superior benefit compared with placebo. However, diclofenac alone demonstrated efficacy comparable with placebo, and therefore its addition to capsaicin added no increased pain relief over capsaicin alone.

RESUMO
AIMS: Heart failure (HF) is associated with considerable symptom burden and impairment in physical functioning and quality of life. The sodium-glucose co-transporter 2 inhibitor empagliflozin reduced the risk of HF hospitalisation and cardiovascular death in patients with type 2 diabetes and established cardiovascular disease in the EMPA-REG OUTCOME trial, and could potentially improve congestion symptoms and exercise capacity in patients with HF. We describe the designs of the EMPERIAL-Preserved and EMPERIAL-Reduced trials of empagliflozin in patients with chronic stable HF, with or without type 2 diabetes. METHODS: EMPERIAL-Preserved and EMPERIAL-Reduced are randomised, placebo-controlled trials designed to investigate the effects of empagliflozin on exercise capacity and patient-reported outcomes in patients with chronic stable HF with preserved ejection fraction [HFpEF; left ventricular ejection fraction (LVEF) > 40%] and HF with reduced ejection fraction (HFrEF; LVEF ≤ 40%), respectively. In each trial, approximately 300 patients will be randomised 1:1 to receive empagliflozin 10 mg or placebo once daily for 12 weeks. In both trials, the primary endpoint is the change from baseline in 6-min walk test distance at week 12. Key secondary endpoints are the change from baseline in Kansas City Cardiomyopathy Questionnaire total symptom score and change from baseline in dyspnoea score of the Chronic Heart Failure Questionnaire at week 12. CONCLUSION: The EMPERIAL-Preserved and EMPERIAL-Reduced trials will determine the effects of empagliflozin on exercise capacity and patient-reported outcomes in patients with HFpEF and HFrEF, respectively, and provide insight into the potential of empagliflozin in the treatment of patients with HF. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT03448406 (EMPERIAL-Preserved), NCT03448419 (EMPERIAL-Reduced).

INTRODUCTION: We used European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) data from the LUME-Colon 1 study to illustrate different methods of statistical analysis for health-related quality of life (HRQoL), and compared the results. PATIENTS AND METHODS: Patients were randomized 1:1 to receive nintedanib 200 mg twice daily plus best supportive care (n = 386) or matched placebo plus best supportive care (n = 382). Five methods (mean treatment difference averaged over time, using a mixed-effects growth curve model; mixed-effects models for repeated measurements (MMRM); time-to-deterioration (TTD); status change; and responder analysis) were used to analyze EORTC QLQ-C30 global health status (GHS)/QoL and scores from functional scales. RESULTS: Overall, GHS/QoL and physical functioning deteriorated over time. Mean treatment difference slightly favored nintedanib over placebo for physical functioning (adjusted mean, 2.66; 95% confidence interval [CI], 0.97-4.34) and social functioning (adjusted mean, 2.62; 95% CI, 0.66-4.47). GHS/QoL was numerically better with nintedanib versus placebo (adjusted mean, 1.61; 95% CI, -0.004 to 3.27). MMRM analysis had similar results, with better physical functioning in the nintedanib group at all timepoints. There was no significant delay in GHS/QoL deterioration (10%) and physical functioning (16%) with nintedanib versus placebo (TTD analysis). Status change analysis showed a higher proportion of patients with markedly improved GHS/QoL and physical functioning in the nintedanib versus placebo groups. Responder analysis showed a similar, less pronounced pattern. CONCLUSION: Analyses of EORTC QLQ-C30 data showed that HRQoL was not impaired by treatment with nintedanib versus placebo. Analysis and interpretation of HRQoL endpoints should consider symptom type and severity and course of disease.

BACKGROUND: The global Phase III LUX-Lung 8 trial (ClinicalTrials.gov: NCT01523587) identified significant improvements in progression-free survival (PFS), overall survival (OS), and patient-reported outcomes (PROs) with second-line afatinib vs erlotinib in patients with advanced squamous cell carcinoma (SCC) of the lung. MATERIALS AND METHODS: We conducted a post hoc analysis of data for patients in LUX-Lung 8 from mainland China (n=67). Compared with erlotinib, afatinib reduced the risk of disease progression or death (PFS) in the Chinese subgroup by 30% (HR=0.70; 95% CI: 0.38-1.27). RESULTS: The risk of death was reduced by 31% (HR=0.69; 95% CI: 0.39-1.21). The proportion of Chinese patients with improvements in PROs also favored afatinib vs erlotinib (global health status/quality of life [QoL], 52.8% vs 29.6%, P=0.072; dyspnea, 47% vs 26%, P=0.091; "dyspnea walked", 44% vs 15%, P=0.017; QoL rate, 53% vs 26%, P=0.037). DISCUSSION: While this analysis was not powered to demonstrate differences compared to the overall trial population (OTP), and there were some differences in baseline characteristics (eg, the proportion of patients aged ≥65 years old), the benefits of afatinib treatment in Chinese patients with SCC of the lung appeared to be at least comparable to that observed in LUX-Lung 8. As with the OTP, the most common adverse events (AEs) with afatinib in the Chinese subgroup were diarrhea and rash/acne, and the incidence and type of the most frequently occurring AEs were similar. CONCLUSION: The results suggest that afatinib represents a feasible treatment option for Chinese patients with advanced SCC of the lung following progression on platinum-based chemotherapy.
RESUMO
INTRODUCTION: Non-small-cell lung cancer (NSCLC) is the leading cause of cancer death in China. Four epidermal growth factor receptor (EGFR)-targeted tyrosine kinase inhibitors - afatinib, erlotinib, icotinib, and gefitinib - are available for first-line treatment of NSCLC in China; however, there are few data to guide treatment choice. The Phase III LUX-Lung 6 trial compared afatinib with platinum-based chemotherapy for first-line treatment of patients from Southeast Asia with EGFR mutation-positive advanced NSCLC. This post hoc analysis assessed the findings from LUX-Lung 6 in Chinese patients. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov: NCT01121393. MATERIALS AND METHODS: Previously untreated patients with EGFR mutation-positive stage IIIB/IV lung adenocarcinoma were randomized 2:1 to receive afatinib or ≤6 cycles of gemcitabine/ cisplatin. The key outcomes were progression-free survival (PFS; primary), objective response rate, disease control rate, overall survival (OS), duration of response and disease control, patient-reported outcomes, and safety. Three hundred and twenty-seven patients from mainland China were treated (89.8% of overall LUX-Lung 6 population; afatinib 217, gemcitabine/cisplatin 110). RESULTS: PFS was significantly longer with afatinib than gemcitabine/cisplatin (median 11.0 versus 5.6 months; hazard ratio [HR], 0.30 [95% CI, 0.21, 0.43]; P,0.0001). Overall, there was no significant difference in OS between treatment arms; however, in a subgroup analysis, afatinib significantly improved OS versus gemcitabine/cisplatin in patients with an EGFR Del19 mutation (median 31.6 versus 16.3 months; HR, 0.61 [95% CI, 0.41, 0.91]; P=0.0146). Afatinib was well tolerated, with most treatment-related adverse events (TRAEs) being of grade 1 or 2 severity. The most common grade 3/4 TRAEs with afatinib were rash/acne (15.9%/0.5%), stomatitis (6.1%/0%), and diarrhea (5.6%/0%). TRAEs leading to permanent discontinuation were reported in 12 patients (5.6%) receiving afatinib and 43 (41.7%) receiving gemcitabine/cisplatin. Afatinib significantly improved PFS compared with standard first-line chemotherapy in Chinese patients with EGFR mutation-positive NSCLC and demonstrated a manageable safety profile. CONCLUSION: The findings support the rationale for using afatinib as a first-line treatment option for this patient population.
RESUMO
BACKGROUND: Afatinib is approved in the US, Europe, and several other regions for first-line treatment for epidermal growth factor receptor mutation-positive (EGFRm+) non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Treatment-naive patients with advanced EGFRm+ NSCLC were randomized to afatinib (40 mg/d) versus cisplatin/pemetrexed (LUX-Lung 3 [LL3]) or cisplatin/gemcitabine (LUX-Lung 6 [LL6]), or versus gefitinib (250 mg/d; LUX-Lung 7 [LL7]). We report subgroup analyses according to age, including 65 years or older versus younger than 65 years (preplanned; LL3/LL6) and additional cutoffs up to 75 years and older (exploratory; LL7). Progression-free survival (PFS), overall survival (OS), and adverse events (AEs) were evaluated. RESULTS: Among the 134 of 345 (39%) and 86 of 364 (24%) patients aged 65 years and older in LL3 and LL6, median PFS was improved with afatinib versus chemotherapy (LL3: hazard ratio [HR], 0.64 [95% confidence interval (CI), 0.39-1.03]; LL6: HR, 0.16 [95% CI, 0.07-0.39]). Afatinib significantly improved OS versus chemotherapy in elderly patients with Del19+ NSCLC in LL3 (HR, 0.39 [95% CI, 0.19-0.80]). Among the 40 of 319 patients (13%) aged 75 years or older in LL7, median PFS (HR, 0.69 [95% CI, 0.33-1.44]) favored afatinib, consistent with the overall population. Afatinib-associated AEs in older patients were consistent with the overall populations. CONCLUSIONS: Subgroup analyses of the LL3, LL6, and LL7 trials show that afatinib is an effective and tolerable treatment for patients with EGFRm+ NSCLC, independent of age.
