Background:The mineralocorticoid receptor antagonist eplerenone improved clinical outcomes among patients with heart failure with reduced ejection faction (HFrEF) in the EMPHASIS-HF (Eplerenone in Mild Patients Hospitalization And SurvIval Study in Heart Failure) study. However, similar efficacy and safety have not been established in Japanese patients. We evaluated the efficacy and safety of eplerenone in patients with HFrEF in a multicenter, randomized, double-blind placebo-controlled outcome study (ClinicalTrials.gov Identifier: NCT01115855). The aim of the study was to evaluate efficacy predefined as consistency of the primary endpoint with that of EMPHASIS-HF at a point estimate of <1 for the hazard ratio.Methods and Results:HFrEF patients with NYHA functional class II–IV and an EF ≤35% received eplerenone (n=111) or placebo (n=110) on top of standard therapy for at least 12 months. The primary endpoint was a composite of death from cardiovascular causes or hospitalization for HF. The primary endpoint occurred in 29.7% of patients in the eplerenone group vs. 32.7% in the placebo group [hazard ratio=0.85 (95% CI: 0.53–1.36)]. Hospitalization for any cause and changes in plasma BNP and LVEF were favorable with eplerenone. A total of 17 patients (15.3%) in the eplerenone group and 10 patients (9.1%) in the placebo group died. Adverse events, including hyperkalemia, were similar between the groups.Conclusions:Eplerenone was well-tolerated in Japanese patients with HFrEF and showed results consistent with those reported in the EMPHASIS-HF study.

Background:Anticoagulation is recommended as standard of care for venous thromboembolism (VTE) (pulmonary embolism [PE]/deep vein thrombosis [DVT]), for which unfractionated heparin (UFH) and warfarin are used in Japan. In the multi-regional AMPLIFY study, a fixed-dose regimen of apixaban alone was non-inferior to conventional therapy for treatment of PE/DVT and was associated with significantly fewer bleeding events.Methods and Results:Japan phase 3 study (AMPLIFY-J), randomized, active-controlled, open-label study in Japanese subjects with acute PE/DVT, was designed based on AMPLIFY. Key objectives were to investigate safety and efficacy of apixaban in symptomatic PE/DVT subjects during 24-week treatment. UFH/warfarin was used as control treatment. Apixaban was initiated at 10 mg twice daily for 7 days, followed by 5 mg twice daily for 23 weeks. All endpoints and imaging for thrombotic burden were assessed by an event adjudication committee. Eighty subjects were randomized, 33 subjects (41.3%) were aged <65 years. Proportion of major/clinically relevant non-major bleeding was lower in apixaban (7.5%) compared with well-controlled UFH/warfarin (28.2%; median TTR, 70.1%). Recurrent VTE occurred in no subjects in apixaban and in 1 subject in UFH/warfarin. Thrombotic burden results were similar in both groups. Proportions of subjects with adverse events was generally similar in both groups.Conclusions:Apixaban was well-tolerated and had a favorable safety profile. No clinically important efficacy difference compared with UFH/warfarin was observed.
