Clinical Trial Summary

This study is a prospective, open-label, single-arm intervention study in African-American/Black subjects with heart failure and reduced ejection fraction (HFrEF). There will be a 7-day screening period, a 57-day open-label treatment period, and a safety follow-up at day 87 or 30 days after the last administration of the investigational product.


Description:

The goal of this study is to determine the impact of adding ivabradine therapy to the standard of care (SOC) in African-American/Black subjects with Heart Failure (HF) and reduced ejection fraction (HFrEF) on changes in heart rate (HR) from baseline (SOC alone). Changes in HR from baseline will be correlated with the changes from baseline in activity level of the subjects, as measured by both a standard 6-minute walk distance and an accelerometer device. The primary hypothesis is that ivabradine effectively reduces HR between baseline and day 57 in African-American/Black subjects. Because mean reductions of approximately 5 beat per minute (bpm) have been observed in the overall placebo-treated subjects in the SHIFT study as well as in the placebo-treated subjects of the subgroup analysis of non-African-American/Black subjects enrolled in the SHIFT study, we will test whether the mean reduction with ivabradine exceeds 5 bpm, and estimate the degree to which the mean reduction with ivabradine exceeds 5 bpm.

Other investigational procedures while participating in this study are excluded. - Female subject is pregnant or breastfeeding or planning to become pregnant or breastfeed during treatment and for an additional 14 days after the last dose of investigational product. Females of childbearing potential should only be included in the study after a confirmed menstrual period and a negative highly sensitive urine pregnancy test. - Female subjects of childbearing potential unwilling to use 1 highly effective method of contraception during treatment and for an additional 14 days after the last dose of investigational product. - Subject has known sensitivity to any of the products or components to be administered during dosing. - Subject likely not to be available to complete all protocol required study visits or procedures, and/or to comply with all required study procedures to the best of the subject and investigator's knowledge. - History or evidence of any other clinically significant disorder, condition or disease (with the exception of those outlined above) that, in the opinion of the investigator or Amgen physician, if consulted, would pose a risk to subject safety or interfere with the study evaluation, procedures or completion.

Outcome

Type Measure Description Time frame Safety issue
Primary Change From Baseline in Heart Rate (HR) at Day 57 Summary is based on observed data, and no imputation is used for missing values.
Least-square mean is from the repeated measures model which includes scheduled visits and baseline HR measurement as covariates.
The mean change from baseline in heart rate is compared to -5 beats/min which is observed in the placebo group in the Systolic Heart Failure Treatment with the IF Inhibitor Ivabradine Trial (SHIFT) study ( NCT02441218, PMID 20801500).
Day1 (baseline), Day 57
