结局指标
主要结局
Change From Baseline in Hemoglobin (Hb) to the Average Over the Primary Efficacy Period (Weeks 24 to 36)
时间窗: Baseline; Weeks 24 to 36
The Baseline average was calculated as the average of the Hb values obtained at the screening visit closest to the date of randomization and the randomization visit. The average for the Primary Efficacy Period was calculated as the average Hb value over Weeks 24 to 36. Analysis was conducted using an analysis of covariance (ANCOVA) model with multiple imputation for missing data with Baseline hemoglobin concentration (\<10.0 versus ≥10.0 g/dL), geographic region (United States \[US\] versus European Union \[EU\] versus Rest of World \[ROW\]), and New York Heart Association congestive heart failure (NYHA CHF) class (Class 0 \[no CHF\] or I versus II or III) as covariates.
Median Time to First Major Adverse Cardiovascular Event (MACE)
时间窗: Up to 170 weeks
MACE was defined as all-cause mortality, non-fatal myocardial infarction (MI), or non-fatal stroke. The primary safety outcome was positively adjudicated first MACE, which was defined as any death, Endpoint Adjudication Committee (EAC)-confirmed non-fatal MI, or EAC-confirmed non-fatal stroke occurring between the first dose date and each participant's last participation date. INNOVATE MACE results and analysis, by design, was performed on pooled data from studies AKB-6548-CI-0016 (NCT02865850) and AKB-6548-CI-0017 (NCT02892149). Results and statistical analysis from study AKB-6548-CI-0017 has been reported in below table and under section "Statistical Analysis 1". Results and statistical analysis of the pooled data from studies AKB-6548-CI-0016 and AKB-6548-CI-0017 has been reported under section "Statistical Analysis 2" of this outcome measure.
