RESUMO

CONTEXT: VERTIS CV evaluated the cardiovascular safety of ertugliflozin in patients with type 2 diabetes and atherosclerotic cardiovascular disease (ASCVD). OBJECTIVE: The aim of these analyses was to assess the insulin requirements of VERTIS CV patients over the trial duration. METHODS: Patients received ertugliflozin 5 mg, 15 mg, or placebo once daily; mean follow-up was 3.5 years. Time to insulin initiation in patients who were insulin naïve at baseline, change in insulin dose in patients receiving baseline insulin, and hypoglycemia incidence in both patient groups were assessed. RESULTS: In VERTIS CV, mean duration of type 2 diabetes was 13.0 years; glycated hemoglobin was 8.2%. Among 4348 (53%) insulin-naïve patients, the likelihood of insulin initiation was significantly reduced with ertugliflozin vs placebo (ertugliflozin 5 mg: hazard ratio [HR] 0.70, 95% CI 0.58-0.84; ertugliflozin 15 mg: HR 0.64, 95% CI 0.53-0.78). Time to insulin initiation was delayed with ertugliflozin; the estimated delay in reaching a 10% cumulative incidence of new insulin initiations vs placebo was 399 days with ertugliflozin 5 mg and 669 days with ertugliflozin 15 mg. Among 3898 (47%) patients receiving baseline insulin, the likelihood of requiring a ≥20% increase in insulin dose was significantly reduced with ertugliflozin vs placebo (ertugliflozin 5 mg: HR 0.62, 95% CI 0.52-0.75; ertugliflozin 15 mg: HR 0.51, 95% CI 0.41-0.62). The incidence of hypoglycemia events was not increased with ertugliflozin treatment. CONCLUSION: In VERTIS CV patients, ertugliflozin reduced the likelihood of insulin initiation, delayed the time to insulin initiation by up to ∼1.8 years, and reduced insulin dose requirements vs placebo, without increasing hypoglycemia events.

RESUMO

INTRODUCTION: The objective of this analysis was to assess disease activity metrics using a variety of disease outcome measures following methotrexate (MTX) withdrawal in ORAL Shift, a phase 3b/4 study of tofacitinib with/without MTX, in patients with rheumatoid arthritis (RA) achieving Clinical Disease Activity Index (CDAI)-defined low disease activity (LDA). METHODS: Patients aged ≥ 18 years with active RA and an inadequate response to MTX received open-label tofacitinib modified-release 11 mg once daily plus MTX for 24 weeks. In the double-blind MTX withdrawal phase, those who had achieved CDAI LDA (≤ 10) at week 24 were randomised 1:1 to receive tofacitinib monotherapy or continued tofacitinib plus MTX. Efficacy analyses were performed in subgroups defined by whether remission and/or LDA had been achieved at week 24 with: Disease Activity Score in 28 joints, erythrocyte sedimentation rate [DAS28-4(ESR)], Routine Assessment of Patient Index Data 3 (RAPID3), CDAI and Simplified Disease Activity Index (SDAI); or DAS28-4[C-reactive protein(CRP)] < 2.4/ < 2.6/ < 2.9/ ≤ 3.2. RESULTS: Five hundred and thirty patients received treatment in the double-blind MTX withdrawal phase. Proportions of patients achieving each disease activity criterion at week 24 varied by metric. Across disease activity metrics [excluding DAS28-4(ESR) remission], 58-89% of patients per group, and numerically more patients receiving tofacitinib plus MTX, achieved the same criterion at week 48 as at week 24. Differences between groups in least squares mean change from baseline (Δ) DAS28-4(ESR) from week 24-48 favoured tofacitinib plus MTX (nominal p values < 0.05). RAPID3 and DAS28-4(CRP) estimated a higher proportion of patients with acceptable disease state versus DAS28-4(ESR), CDAI remission and SDAI remission. CONCLUSION: Response rates at the beginning of the double-blind phase varied across metrics. A consistent trend towards higher response rates with tofacitinib plus MTX was observed across metrics after randomisation, with nominal differences in DAS28-4(ESR) responses. Compared with continued combination therapy, MTX withdrawal did not lead to a clinically meaningful reduction in the response to tofacitinib. DAS28-4(CRP) and RAPID3 were the least stringent metrics.

RESUMO

OBJECTIVE: Tofacitinib is an oral Janus kinase for the treatment of rheumatoid arthritis (RA). This post hoc analysis assessed whether baseline body mass index (BMI) impacts tofacitinib efficacy in patients with RA. METHODS: Pooled data from six phase 3 studies in patients receiving tofacitinib 5 mg (N=1589) or 10 mg (N=1611) twice daily or placebo (advancing to active treatment at months 3 or 6; N=680), ±conventional synthetic disease-modifying antirheumatic drugs, were stratified by baseline BMI (<25, 25 to <30, ≥30 kg/m2). Endpoints (through to month 6) were assessed descriptively: American College of Rheumatology 20/50/70 response rates; changes from baseline (∆) in Disease Activity Score in 28 joints, erythrocyte sedimentation rate (DAS28-4(ESR)), DAS28-4(C-reactive protein), Clinical Disease Activity Index (CDAI), Health Assessment Questionnaire-Disability Index (HAQ-DI) and pain; and proportions of patients achieving DAS28-4(ESR) ≥1.2 and HAQ-DI ≥0.22 decreases from baseline, low disease activity (DAS28-4(ESR) ≤3.2 or CDAI ≤10) and radiographic non-progression (Δmodified Total Sharp Score ≤0.5; months 12 and 24). Estimates were adjusted using multivariable models for selected outcomes. Univariate/multivariable regression analyses determined predictors of month 6 outcomes. RESULTS: Of 3880 patients included, 1690 (43.6%), 1173 (30.2%) and 1017 (26.2%) had baseline BMI <25, 25 to <30 and ≥30 kg/m2, respectively. Tofacitinib showed greater efficacy improvements versus placebo in each BMI category. Differences in efficacy outcomes (adjusted and unadjusted) were generally not clinically meaningful across BMI categories within treatment groups. In regression analyses, BMI was not consistently associated with selected outcomes. CONCLUSIONS: Baseline BMI did not consistently affect tofacitinib response suggesting that tofacitinib is an effective oral treatment option for adults with moderate to severe RA regardless of baseline BMI, including patients with BMI ≥30 kg/m2.

RESUMO

BACKGROUND: This post hoc analysis assessed clinical and functional responses to tofacitinib monotherapy, tofacitinib + methotrexate (MTX), and adalimumab + MTX, in patients with rheumatoid arthritis enrolled in the ORAL Strategy study, including evaluation of patient-level data using cumulative probability plots. METHODS: In the 12-month, phase IIIb/IV ORAL Strategy study, patients with rheumatoid arthritis and an inadequate response to MTX were randomized to receive tofacitinib 5 mg twice daily (BID), tofacitinib 5 mg BID + MTX, or adalimumab 40 mg every other week + MTX. In this post hoc analysis, cumulative probability plots were generated for mean percent change from baseline (%∆) in the Clinical Disease Activity Index (CDAI; clinical response) and mean change from baseline (∆) in the Health Assessment Questionnaire-Disability Index (HAQ-DI; functional response) at month 12. Median C-reactive protein (CRP) levels by time period were summarized by CDAI remission (≤ 2.8) status at months 6 and 12. RESULTS: Data for 1146 patients were analyzed. At month 12, cumulative probability plots for %∆CDAI and ∆HAQ-DI were similar across treatments in patients with greater response. At lower levels of response, patients receiving tofacitinib monotherapy did not respond as well as those receiving combination therapies. With tofacitinib + MTX, numerically higher baseline CRP levels and numerically larger post-baseline CRP reductions were seen in patients achieving CDAI remission at months 6 and 12 vs those who did not. CONCLUSIONS: These results suggest that patients with a greater response did well, irrespective of which therapy they received. Patients with lesser response had better outcomes with combination therapies vs tofacitinib monotherapy, suggesting they benefitted from MTX. High pre-treatment CRP levels may be associated with better response to tofacitinib + MTX. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02187055. Registered on 08 July 2014.

RESUMO

OBJECTIVES: To report the efficacy, safety and patient-reported outcome measures (PROs) of tofacitinib modified-release 11 mg once daily plus methotrexate in patients with rheumatoid arthritis (RA) from the open-label phase of Oral Rheumatoid Arthritis Trial (ORAL) Shift. METHODS: ORAL Shift was a global, 48-week, phase 3b/4 withdrawal study in patients with moderate to severe RA and an inadequate response to methotrexate. Patients received open-label tofacitinib modified-release 11 mg once daily plus methotrexate; those who achieved low disease activity (LDA; Clinical Disease Activity Index (CDAI)≤10) at week 24 were randomised to receive blinded tofacitinib 11 mg once daily plus placebo (ie, blinded methotrexate withdrawal) or continue with blinded tofacitinib 11 mg once daily plus methotrexate for another 24 weeks. Efficacy, PROs and safety from the open-label phase are reported descriptively. RESULTS: Following screening, 694 patients were enrolled and received tofacitinib plus methotrexate in the open-label phase. At week 24, 527 (84.5%) patients achieved CDAI-defined LDA. Improvements from baseline to weeks 12 and 24 were generally observed for all efficacy outcomes (including measures of disease activity, and response, LDA and remission rates) and PROs. Adverse events (AEs), serious AEs and discontinuations due to AEs were reported by 362 (52.2%), 20 (2.9%) and 41 (5.9%) patients, respectively. No deaths were reported. CONCLUSIONS: Tofacitinib modified-release 11 mg once daily plus methotrexate conferred improvements in disease activity measures, functional outcomes and PROs, with most (84.5%) patients achieving CDAI-defined LDA after 24 weeks of open-label treatment; the safety profile was generally consistent with the historic safety profile of tofacitinib.Funded by Pfizer Inc; NCT02831855.

RESUMO

AIM: To assess the efficacy and safety of ertugliflozin in patients with type 2 diabetes mellitus (T2DM) and established atherosclerotic cardiovascular disease (ASCVD) inadequately controlled by insulin. MATERIALS AND METHODS: VERTIS CV was the cardiovascular outcome study for ertugliflozin. Patients were randomly assigned to placebo, or ertugliflozin 5 mg or 15 mg once daily. We report the results of a substudy in patients on a stable dose of insulin ≥20 units/d. The primary endpoint was glycated haemoglobin (HbA1c) change from baseline to 18 weeks. Secondary endpoints were changes in fasting plasma glucose (FPG), body weight (BW), the proportion of patients with HbA1c <53 mmol/mol (<7%), systolic blood pressure (SBP), diastolic blood pressure and insulin dose. RESULTS: Of 8246 patients randomized in VERTIS CV, 1065 were included in the substudy (68.2% men, mean [SD] age 64.8 [7.8] years, T2DM duration 16.7 [9.0] years, HbA1c 8.4 [1.0]%). At week 18, the least squares (LS) mean change from baseline in HbA1c was significantly greater with ertugliflozin 5 mg and 15 mg versus placebo (placebo-adjusted LS mean change -0.58%, 95% confidence interval [CI] -0.71, -0.44 and -0.65%, 95% CI -0.78, -0.51, respectively; P < 0.001 for both). Ertugliflozin significantly reduced FPG, BW and SBP. In women, the incidence of genital mycotic infections was higher with ertugliflozin (3.5%) versus placebo (0.0%). The incidence of symptomatic hypoglycaemia was similar across treatment groups. CONCLUSIONS: Ertugliflozin added to insulin improved glycaemic control, BW and SBP versus placebo at 18 weeks in patients with T2DM and ASCVD.

RESUMO

BACKGROUND: Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). We examined the degree to which Patient Global Assessment of Disease Activity (PtGA) was driven by patient-reported assessments of pain (Pain), physical function, and fatigue in patients receiving tofacitinib 5 mg twice daily or placebo, each with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs). METHODS: This post hoc analysis used data pooled from three randomized controlled trials in csDMARD-inadequate responder (csDMARD-IR) patients (ORAL Scan: NCT00847613; ORAL Standard: NCT00853385; ORAL Sync: NCT00856544). Using subgroup analysis from 2 × 2 tables, associations between PtGA and Pain, Health Assessment Questionnaire-Disability Index (HAQ-DI), and Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) at month 3 were evaluated using Pearson's Phi correlation coefficients. To support the main analysis, associations between select patient-reported outcomes (PROs) were also evaluated in csDMARD-naïve (ORAL Start; NCT01039688) and biologic (b)DMARD-IR (ORAL Step; NCT00960440) patients. RESULTS: Across csDMARD-IR treatment groups, low disease activity (defined as PtGA ≤ 20 mm), and moderate (≥ 30%) and substantial (≥ 50%) improvements from baseline in PtGA were associated with mild Pain (Visual Analog Scale score ≤ 20 mm), and moderate (≥ 30%) and substantial (≥ 50%) improvements from baseline in Pain; lack of Pain improvement was associated with little/no improvement in PtGA. In contrast, large proportions of csDMARD-IR patients who reported PtGA improvements did not report HAQ-DI or FACIT-F scores ≥ normative values (≤ 0.25 and ≥ 43.5, respectively) or changes in HAQ-DI or FACIT-F scores ≥ minimum clinically important difference (≥ 0.22 and ≥ 4.0, respectively). Generally, PtGA and Pain outcomes were moderately-to-strongly correlated at month 3 in csDMARD-IR patients, with weaker correlations evident between PtGA and HAQ-DI/FACIT-F outcomes. Similar findings were generally evident in csDMARD-naïve and bDMARD-IR patients. CONCLUSIONS: This analysis supports the role of Pain as a key driver of PtGA in RA; physical function and fatigue play lesser roles in patients' perceptions of disease activity. These findings corroborate the importance of improved PROs and attainment of low symptom states for optimizing patient care.

RESUMO

Introduction: Pediatric thyroidectomy is performed by a variety of surgical specialties. Thyroidectomy can result in a number of complications. Previous studies cite that the most common complications in children are pain and transient hypocalcemia. The purposes of this report are to assess the adverse events of thyroidectomies performed in the pediatric population and to assess the relationship between surgical specialties and postoperative thyroidectomy complications. Methods: We conducted a cross-sectional analysis of cases from January 1, 2014 through November 1, 2015 using the National Surgical Quality Improvement Program database for patients undergoing excision of cyst or adenoma of the thyroid, unilateral thyroid lobectomy, or total thyroidectomy. Results: Of the 344 patients who underwent thyroidectomy, 10 (2.9%) experienced at least one complication. The most common complications were readmission, surgical site infections, and wound disruption. There was a statistically significant association between complication incidence and surgical specialty (p=0.006). Pediatric otolaryngology had a statistically significantly higher number of complications than pediatric surgery (p<0.008). Conclusion: Overall, the incidence of adverse events following pediatric thyroidectomy was low.

RESUMO

AIM: To evaluate the long-term efficacy and safety of ertugliflozin in adults with type 2 diabetes mellitus inadequately controlled on metformin. MATERIALS AND METHODS: A 104-week Phase III, randomized double-blind study with a 26-week placebo-controlled period (Phase A) and a 78-week period (Phase B) where blinded glimepiride was added to non-rescued placebo participants with fasting fingerstick glucose ≥6.1 mmol/L. Results through week 104 are reported. RESULTS: Mean (standard error) change in HbA1c from baseline was -0.7% (0.07) and -1.0% (0.07) at week 52; -0.6% (0.08) and -0.9% (0.08) at week 104 for ertugliflozin 5 and 15 mg. At week 52, 34.8% and 36.6% participants had HbA1c <7.0%, and 24.6% and 33.7% at week 104, for ertugliflozin 5 and 15 mg. Ertugliflozin reduced fasting plasma glucose (FPG), body weight and systolic blood pressure (SBP) from baseline through week 104. The incidence of female genital mycotic infections (GMIs) was higher with ertugliflozin, and symptomatic hypoglycaemia was lower for ertugliflozin versus placebo/glimepiride. Minimal bone mineral density (BMD) changes were observed, similar to placebo/glimepiride, except at total hip where reduction in BMD was greater with ertugliflozin 15 mg versus placebo/glimepiride: difference in least squares means (95% CI) -0.50% (-0.95, -0.04) at week 52 and -0.84% (-1.44, -0.24) at week 104. CONCLUSIONS: Ertugliflozin maintained improvements from baseline in HbA1c, FPG, body weight and SBP through week 104. Ertugliflozin was well tolerated, with non-clinically relevant changes in BMD. Compared with placebo/glimepiride, ertugliflozin increased female GMIs, but reduced the incidence of symptomatic hypoglycaemia. ClinicalTrials.gov Identifier: NCT02033889.

RESUMO

OBJECTIVE: Aldosterone stimulates cardiac collagen synthesis. Circulating biomarkers of collagen turnover provide a useful tool for the assessment of cardiac remodeling in patients with an acute myocardial infarction (MI). METHODS: The REMINDER trial assessed the effect of eplerenone in patients with an acute ST-elevation Myocardial Infarction (STEMI) without known heart failure (HF), when initiated within 24 h of symptom onset. The primary outcome was almost totally (>90%) driven by natriuretic peptide (NP) thresholds after 1-month post-MI (it also included a composite of cardiovascular death or re-hospitalization or new onset HF or sustained ventricular tachycardia or fibrillation or LVEF ≤40% after 1-month post-MI). This secondary analysis aims to assess the extracellular matrix marker (ECMM) levels with regards to: (1) patients` characteristics; (2) determinants; (3) and eplerenone effect. RESULTS: Serum levels of ECMM were measured in 526 (52%) of the 1012 patients enrolled in the REMINDER trial. Patients with procollagen type III N-terminal propeptide (PIIINP) above the median were older and had worse renal function (p < 0.05). Worse renal function was associated with increased levels of PIIINP (standardized ß ≈ 0.20, p < 0.05). Eplerenone reduced PIIINP when the levels of this biomarker were above the median of 3.9 ng/mL (0.13 ± 1.48 vs. -0.37 ± 1.56 ng/mL, p = 0.008). Higher levels of PIIINP were independently associated with higher proportion of NP above the prespecified thresholds (HR = 1.95, 95% CI 1.16-3.29, p = 0.012). CONCLUSIONS: Eplerenone effectively reduces PIIINP levels when baseline values were above the median. Eplerenone may limit ECMM formation in post-MI without HF.

RESUMO

AIM: We evaluated the efficacy and safety of ertugliflozin, an SGLT2 inhibitor, in type 2 diabetes mellitus (T2DM) inadequately controlled (HbA1c, 7.0%-10.5%) with metformin monotherapy (≥1500 mg/d for ≥8 weeks). METHODS: This was a double-blind, 26-week, multicentre study with ongoing 78-week extension (ClinicalTrials.gov identifier: NCT02033889). A total of 621 participants were randomized 1:1:1 to placebo, or ertugliflozin 5 or 15 mg/d. The primary endpoint was change from baseline at week 26 in HbA1c. Secondary efficacy endpoints were change from baseline at week 26 in fasting plasma glucose (FPG), body weight, systolic/diastolic blood pressure (SBP/DBP) and number of participants with HbA1c <7.0% (53 mmol/mol). Pre-specified adverse events (AEs) of special interest and percent change from baseline in bone mineral density (BMD) were also assessed at week 26. RESULTS: At week 26, the placebo-adjusted least-squares mean change from baseline HbA1c (8.1%) was -0.7% and -0.9% for ertugliflozin 5 and 15 mg, respectively (both P < .001), to final means of 7.3% and 7.2%, respectively. The odds of HbA1c <7.0% were significantly greater in both ertugliflozin groups vs placebo. Ertugliflozin significantly reduced FPG, body weight, SBP and DBP vs placebo. The incidence of genital mycotic infections was higher in the ertugliflozin groups (female subjects: placebo, 0.9%; ertugliflozin 5 mg, 5.5%; ertugliflozin 15 mg, 6.3% [P = .032]; male subjects: 0%; 3.1%; 3.2%, respectively), as was the incidence of urinary tract infections and symptomatic hypoglycaemia. The incidence of hypovolaemia AEs was similar across groups. Ertugliflozin had no adverse impact on BMD at week 26. CONCLUSIONS: Ertugliflozin added to metformin in patients with inadequately controlled T2DM improved glycaemic control, reduced body weight and BP, but increased the incidence of genital mycotic infections.

RESUMO

AIMS: Although hypokalaemia is common among patients with heart failure (HF), the prognostic significance of baseline hypokalaemia and hypokalaemia during follow-up in HF patients receiving a mineralocorticoid receptor antagonist (MRA) remains uncertain. METHODS AND RESULTS: Results of the EMPHASIS-HF trial in patients (n = 2737) with HF and reduced EF with mild symptoms, randomized to eplerenone or placebo, were analysed with regard to the presence or occurrence of hypokalaemia (serum K+ <4.0 mmol/L) and the risk of cardiovascular death or hospitalization for HF (primary endpoint). Median follow-up was 21 months. Baseline hypokalaemia and hypokalaemia during follow-up were common occurrences (19.6% and 40.6%, respectively). Hypokalaemia during follow-up was associated with worse outcomes in multivariable analyses [hazard ratio (HR) 1.26, 95% confidence interval (CI) 1.05-1.52, P = 0.01] without evidence of interaction with eplerenone. In contrast, baseline hypokalaemia was associated with outcomes in the placebo group (HR 1.37, 95% CI 1.05-1.79, P = 0.02) but not in the eplerenone group (HR 0.87, 95% CI 0.62-1.23, P = 0.44; P for interaction = 0.04). Concurrently, eplerenone was found to be more protective in patients with baseline hypokalaemia vs. patients without baseline hypokalaemia compared with placebo (HR 0.44, 95% 0.30-0.64, P < 0.0001 vs. 0.69, 95% CI 0.57-0.83, P = 0.0001; P for interaction = 0.04). In patients without baseline hypokalaemia, eplerenone use decreased the rate of hypokalaemia during follow-up (HR 0.69, 95% CI 0.59-0.80, P < 0.001). A potassium level >4.0 mmol/L at 1 month after randomization mediated 26.0% (0.6-51.4%) of the eplerenone treatment effect (P = 0.04). CONCLUSION: In HF patients receiving optimal therapy but not treated with eplerenone, baseline hypokalaemia was associated with worse outcomes. Conversely, hypokalaemia amplified the treatment effect of eplerenone.

RESUMO

AIMS: We aimed to assess the impact of eplerenone on cardiovascular (CV) outcomes in STEMI without known heart failure, when initiated within 24 h of symptom onset. METHODS AND RESULTS: In this randomized, placebo-controlled, double-blind trial, we assigned 1012 patients with acute STEMI and without a history of heart failure to receive either eplerenone (25-50 mg once daily) or placebo in addition to standard therapy. The primary endpoint was the composite of CV mortality, re-hospitalization, or, extended initial hospital stay, due to diagnosis of HF, sustained ventricular tachycardia or fibrillation, ejection fraction ≤40%, or elevated BNP/NT-proBNP at 1 month or more after randomization. BNP elevation was defined as BNP levels or values above 200 pg/mL or NT-proBNP values above 450 pg/mL (in patients aged below 50); above 900 pg/mL (age 50-75 years) or above 1800 pg/mL (patients older than 75). After a mean follow-up of 10.5 months, the primary endpoint occurred in 92 patients (18.2%) in the eplerenone group and in 149 patients (29.4%) in the placebo group [adjusted hazard ratio (HR), 0.58; 95% confidence interval (CI), 0.45-0.76; P < 0.0001]. The primary endpoint was driven by a high BNP/NT-proBNP level (adjusted HR, 0.60; 95% CI, 0.45-0.79; P < 0.0003). Adverse event rates were similar in both groups. Serum potassium levels exceeded 5.5 mmol/L in 5.6 vs. 3.2% (P = 0.09) and were below 3.5 mmol/L in 1.4 vs. 5.6% of patients (P = 0.0002), in the eplerenone and placebo groups, respectively. CONCLUSION: The addition of eplerenone during the acute phase of STEMI was safe and well tolerated. It reduced the primary endpoint over a mean 13 months follow-up mostly because of significantly lower BNP/NT-proBNP levels. Additional studies are needed to clarify the role of early use of MRAs in STEMI patients without heart failure. CLINICAL TRIAL REGISTRATION: NCT01176968.

RESUMO

BACKGROUND: Bazedoxifene/conjugated estrogens (BZA/CE), a novel tissue-selective estrogen complex (TSEC), has been evaluated in the Selective estrogens, Menopause And Response to Therapy (SMART) trials. Secondary outcomes from these trials were evaluated to determine whether the effects of BZA/CE are influenced by years since menopause (YSM). METHODS: SMART-1 and SMART-2 were randomized, double-blind, placebo (PBO)-controlled phase 3 trials in nonhysterectomized postmenopausal women. Outcomes were evaluated for women <5 or ≥5 YSM in SMART-1 (BZA 20 mg/CE 0.45 mg, n=433; BZA 20 mg/CE 0.625 mg, n=414; PBO, n=427) and SMART-2 (BZA 20 mg/CE 0.45 mg, n=127; BZA 20 mg/CE 0.625 mg, n=128; PBO, n=63). Hot-flush frequency and severity, health-related quality of life (HRQoL), sleep, treatment satisfaction, cumulative amenorrhea, and breast pain were assessed for each study individually, using defined statistical analysis protocols. RESULTS: For <5 and ≥5 YSM subgroups, BZA 20 mg/CE 0.45 and 0.625 mg showed significant decreases in hot-flush frequency and severity at 3 months compared with PBO (p<0.05 for both). Both BZA/CE doses showed significant improvements compared with PBO in HRQoL scores, sleep parameters, and satisfaction with treatment at 3 months irrespective of YSM (p≤0.05 vs. PBO for all). Similar to PBO, BZA/CE showed high proportions of cumulative amenorrhea (SMART-1) and low incidences of breast pain (SMART-1 and SMART-2) for women <5 and ≥5 YSM. CONCLUSIONS: The positive effects of BZA/CE on secondary outcomes were consistent among women <5 or ≥5 YSM.

RESUMO

BACKGROUND: Mineralocorticoid receptor antagonists improve outcomes in patients with systolic heart failure but may induce worsening of renal function (WRF) and hyperkalemia (HK). We assessed the risk factors for mineralocorticoid receptor antagonist-related WRF and for HK, as well as the association between HK and WRF with clinical outcomes in the Eplerenone in Mild Patients Hospitalization and Survival Study in Heart Failure (EMPHASIS-HF). METHODS AND RESULTS: Serial changes in estimated glomerular filtration rate and in serum potassium were available in 2737 patients during a median 21-month follow-up. HK variably defined as serum K>4.5, 5, or 5.5 mmol/L occurred in 74.7%, 32.5%, and 8.9% patients enrolled in EMPHASIS-HF, respectively. WRF defined as a decrease in estimated glomerular filtration rate>20% or >30% from baseline occurred in 27% and 14% of patients, respectively. Patients assigned eplerenone displayed modest and early but significant and persistent (1) rise in serum potassium and (2) reduction in estimated glomerular filtration rate when compared with those assigned placebo. In multivariate analyses, eplerenone was associated with a higher incidence of WRF and HK, which were interrelated and also associated with baseline patient characteristics (eg, age≥75 years, hypertension, diabetes mellitus, nonwhite race, ejection fraction<30%, and treatment with an antiarrythmics drug or loop diuretic). Eplerenone retained its survival benefits without any significant interaction with the association between HK>5.5 mmol/L only and WRF and worse outcomes. CONCLUSIONS: In patients with heart failure receiving optimal therapy, WRF and HK were more frequent when eplerenone was added, but their occurrence did not eliminate the survival benefit of eplerenone.

RESUMO

OBJECTIVES: The study sought to investigate the safety and efficacy of eplerenone in patients at high risk for hyperkalemia or worsening renal function (WRF) in EMPHASIS-HF, a trial that enrolled patients at least 55 years old with heart failure and reduced ejection fraction (HF-REF), in New York Heart Association (NYHA) functional class II and with an estimated glomerular filtration rate (eGFR) >30 ml/min/1.73 m(2) and serum potassium <5.0 mmol/l. Patients were receiving optimal therapy and most had been hospitalized for a cardiovascular reason within 180 days of inclusion. BACKGROUND: Underuse of eplerenone in patients with HF-REF may be due to fear of inducing hyperkalemia or WRF in high-risk patients. METHODS: This was a pre-specified analysis of subgroups of patients at high risk of hyperkalemia or WRF (patients ≥ 75 years of age, with diabetes, with eGFR <60 ml/min/1.73 m(2), and with systolic blood pressure < median of 123 mm Hg), examining the major safety measures (potassium >5.5, >6.0, and <3.5 mmol/l; hyperkalemia leading to study-drug discontinuation or hospitalization; and hospitalization for WRF) as well as the primary outcome (hospitalization for HF or cardiovascular mortality). RESULTS: In all high-risk subgroups, patients treated with eplerenone had an increased risk of potassium >5.5 mmol/l but not of potassium >6.0 mmol/l, and of hospitalization for hyperkalemia or discontinuation of study medication due to adverse events. Eplerenone was effective in reducing the primary composite endpoint in all subgroups. CONCLUSIONS: In patients with chronic HF-REF, in NYHA functional class II, and meeting specific inclusion and exclusion criteria, including an eGFR >30 ml/min/1.73 m(2) and potassium <5.0 mmol/l, eplerenone was both efficacious and safe when carefully monitored, even in subgroups at high risk of developing hyperkalemia or WRF.

RESUMO

AIMS: Our objective was to create a simple prognostic risk score for patients with systolic heart failure and mild symptoms. We then assessed the efficacy of eplerenone across different categories of risk. METHODS AND RESULTS: The Eplerenone in Mild Patients Hospitalization and Survival Study in Heart Failure trial (EMPHASIS-HF) was an international randomized trial, comparing eplerenone with placebo in 2737 patients with systolic heart failure and mild symptoms. The primary outcome was a composite of cardiovascular death or hospitalization for heart failure, over a median 2.1 years follow-up. Using multivariable Cox modelling age, sex, systolic blood pressure, estimated glomerular filtration rate, diabetes, BMI, haemoglobin, prior heart failure (HF) hospitalization, prior myocardial infarction/coronary artery bypass surgery (CABG), and heart rate were identified as strong independent risk factors. Estimates from the model were converted into a simple integer risk score which was categorized into three groups of low-, medium-, and high risk. In placebo patients, the rates (per 100 patient-years) for the primary outcome were 7.6, 19.0, and 39.4 in the low-, medium-, and high-risk groups, respectively. On eplerenone, these rates were reduced to 5.6, 12.2, and 24.2, respectively. Eplerenone was beneficial across all risk categories and the hazard ratios were similar. The absolute treatment benefit was greatest among those at highest risk. Similar patterns emerged for all-cause mortality and for all HF hospitalizations. CONCLUSION: This easy-to-use integer risk score should be of value in quantifying individual patient risk in patients with systolic HF and mild symptoms. The relative benefits of eplerenone appeared consistent across the whole spectrum of risk, including those at lower risk.

RESUMO

OBJECTIVE: A post hoc exploratory analysis was conducted to examine correlations between changes in bone density, bone markers, and hot flushes after the treatment of postmenopausal women with bazedoxifene (BZA)/conjugated estrogens (CE). METHODS: In a 2-year phase 3 study, 3,397 postmenopausal women were randomized to BZA 10 mg/CE 0.45 mg, BZA 20 mg/CE 0.45 mg, BZA 40 mg/CE 0.45 mg, BZA 10 mg/CE 0.625 mg, BZA 20 mg/CE 0.625 mg, BZA 40 mg/CE 0.625 mg, raloxifene 60 mg, or placebo. In this analysis, bone density changes at 2 years were compared with baseline levels of the bone markers serum C-telopeptide and osteocalcin. Correlations between changes in bone density and changes in 12-week hot flush composite scores in symptomatic women were also analyzed. RESULTS: Treatment with BZA 20 mg/CE 0.45 mg or BZA 20 mg/CE 0.625 mg increased lumbar spine bone density more in women with higher bone resorption and formation, categorized by baseline levels of C-telopeptide and osteocalcin (P < 0.001, both BZA/CE doses). With placebo, larger decreases in lumbar spine bone density were seen in the highest tertile of serum C-telopeptide. There was no correlation between changes in total hip bone density and baseline bone markers. There were significant correlations between percent change in hot flush score at week 12 and percent changes in lumbar spine (r = -0.31, P = 0.006) and total hip (r = -0.23, P = 0.044) bone densities at month 24. CONCLUSIONS: With 2-year BZA/CE treatment, women with larger increases in lumbar spine and total hip densities also have higher baseline bone markers. Early reductions in hot flush score (12 wk) are predictive of long-term increases in bone density (24 mo).
