Brief Summary
The purpose of this study is to determine if treatment with omecamtiv mecarbil when added to standard of care is well tolerated and superior to placebo in reducing the risk of cardiovascular death or heart failure events in adults with chronic heart failure with reduced ejection fraction (HFrEF).
Brief Title
Registrational Study With Omecamtiv Mecarbil (AMG 423) to Treat Chronic Heart Failure With Reduced Ejection Fraction
Detailed Description
This study was conducted by Amgen as the IND holder, with Cytokinetics as a collaborator. Due to the termination of the collaboration agreement between Amgen and Cytokinetics in May 2021 and subsequent transfer of the omecamtiv mecarbil IND from Amgen to Cytokinetics, Cytokinetics is now listed as the sponsor.

Official Title
A Double-blind, Randomized, Placebo-controlled, Multicenter Study to Assess the Efficacy and Safety of Omecamtiv Mecarbil on Mortality and Morbidity in Subjects With Chronic Heart Failure With Reduced Ejection Fraction (GALACTIC-HF)
Primary Outcomes
Outcome Description
The primary outcome was a composite of a heart-failure (HF) event or cardiovascular (CV) death, whichever occurred first, in a time-to-event analysis.
A heart-failure event was defined as an urgent clinic visit, emergency department visit, or hospitalization for subjectively and objectively worsening heart failure leading to treatment intensification beyond a change in oral diuretic therapy.
All deaths and HF events were adjudicated by an independent external clinical events committee (CEC) at the Duke Clinical Research Institute, using standardized definitions based on the recent American College of Cardiology/American Heart Association (ACC/AHA) standards for endpoint definitions in cardiovascular clinical trials.
Time to cardiovascular death or first HF event was analyzed using Kaplan-Meier (KM) methods. Since the median was not calculated, the percentage of participants with a positively adjudicated event during the study is reported.

Outcome Description
Cardiovascular death includes acute myocardial infarction (MI), sudden cardiac death, death due to heart failure, death due to stroke, death due to cardiovascular (CV) procedures, death due to CV hemorrhage, and death due to other CV causes.
All deaths were adjudicated by an independent external clinical-events committee at the Duke Clinical Research Institute, using standardized definitions based on the recent ACC/AHA standards for endpoint definitions in cardiovascular clinical trials.

Outcome Description
The Kansas City Cardiomyopathy Questionnaire is a self-administered questionnaire with a 2-week recall period that includes 23 items that map to 7 domains: symptom frequency; symptom burden; symptom stability; physical limitations; social limitations; quality of life; and self-efficacy (the patient's understanding of how to manage their heart failure). The symptom frequency and symptom burden domains are merged into a total symptom score. Scores are represented on a 0-to-100-point scale, where lower scores represent more frequent and severe symptoms and scores of 100 indicate no symptoms.
The change from baseline in KCCQ TSS was analyzed separately for each randomization setting (inpatient and outpatient).
Least squares means are from the mixed model which includes baseline total symptom score value, region, baseline eGFR, scheduled visit, treatment group and interaction of treatment with scheduled visit as covariates.

Outcome Description
A HF hospitalization is defined as an event that met all of the following criteria:
1. The participant was admitted to the hospital with a primary diagnosis of HF;
2. The length of stay in the hospital extended for at least 24 hours;
3. The participant exhibited documented new or worsening symptoms due to HF on presentation;
4. The participant had objective evidence of new or worsening HF;
5. The participant received initiation or intensification of treatment specifically for HF, including an intravenous diuretic or vasoactive agent, mechanical or surgical intervention, or mechanical fluid removal.
Events were adjudicated by an independent external CEC at the Duke Clinical Research Institute using standardized definitions based on the ACC/AHA standards for endpoint definitions in CV clinical trials.
Time to first HF hospitalization was analyzed using KM methods. Since the median was not calculated, the percentage of participants with a positively adjudicated event is reported.
