This study is a prospective, open-label, single-arm intervention study in African-American/Black subjects with 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.
|Condition or disease||Intervention/treatment||Phase|
|Heart Failure (HF)||Drug: 5mg Ivabradine||Phase 4|
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 genetic background of a subset of subjects with available genetic data in the studied population, as well as 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.

Experimental: Initial Dose: 5 mg BID
5mg Ivabradine: On day 1, eligible subjects with confirmed sinus rhythm and HR ≥ 70 bpm will be enrolled into a 57-day open-label treatment period. The starting dose of ivabradine is 5 mg twice daily (BID).
2.5mg Ivabradine: In subjects with a history of conduction defects, or in subjects in whom bradycardia could lead to hemodynamic compromise, therapy is to be initiated at 2.5 mg BID.
Changes in HR from baseline will be correlated with the genetic background of the studied population, as well as 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.
Drug: 5mg Ivabradine
On day 15, the 5mg dose will be titrated according to HR :
HR ≥ 60 bpm 7.5 mg BID HR ≥ 50 bpm, < 60 bpm 5.0 mg BID HR < 50 bpm and/or signs or symptoms of bradycardia 2.5 mg BID
Ivabradine dose levels can be adapted to HR at any clinical visit if necessary.
Other Name: Corlanor
