Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Pharmacokinetics (PK): Concentration Before Morning Dose (Cpredose) Over Time
Time Frame: Before morning dose on Week 2 (Day 15), Week 4 (Day 28), Week 12 (Day 84), Week 16 (Day 112)
Before morning dose on Week 2 (Day 15), Week 4 (Day 28), Week 12 (Day 84), Week 16 (Day 112)
PK: Area Under the Curve Until 8 Hours After Morning Dose at Week 8 (AUC0-8)
Time Frame: Week 8 (Day 56) at predose, at 2 hours ±30 minutes; 4 hours ±30 minutes; 6 hours ±30 minutes; 8 hours ±30 minutes after morning dose
Week 8 (Day 56) at predose, at 2 hours ±30 minutes; 4 hours ±30 minutes; 6 hours ±30 minutes; 8 hours ±30 minutes after morning dose

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline at Week 16 in Systolic Ejection Time (SET)
Time Frame: Baseline, Week 16 (Day 112)
LS mean was from the repeated measures model, which included treatment group, stratification factor (from IVRS), scheduled visit, baseline value, and the interaction of treatment group with scheduled visit as covariates.
Baseline, Week 16 (Day 112)

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Treatment-Emergent Adverse Events (TEAEs)
Time Frame: From first dose of study drug up to Week 20 (Day 140 + 3 days)
An adverse event (AE) is defined as any untoward medical occurrence. Serious AEs are defined as AEs that meets at least 1 of the following serious criteria: fatal, life threatening, requires in-patient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, congenital anomaly/birth defect, other medically important serious event. AEs are graded as: 1=mild, 2=moderate, 3=severe, 4=life-threatening, 5=death. TEAEs are defined as events occurring after the first dose of study drug.
From first dose of study drug up to Week 20 (Day 140 + 3 days)

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
