Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
The primary purpose of this clinical trial is to compare the effects of study medicine (Ponsegromab/PF-06946860) with a placebo (an injection that looks like the study medicine but does not contain the active medicine) to find out if the study medicine is better than the placebo (an injection that looks like the study medicine but does not contain the active medicine) for treatment of symptoms related to heart failure. Participants will not know which treatment group they are assigned to. Most participants in this study will receive the study medicine or placebo by shots under the skin every four weeks. People may be able to participate in this study if they have heart failure. Participants will take part in this study for about 9 months. During this time participants will visit the study clinic once a month.

A separate PK cohort within this clinical trial will receive open-label study medicine (Ponsegromab/PF-06946860) only. Participants in this open-label, PK cohort will not receive placebo. These participants will receive the study medicine by shots under the skin every four weeks. People may be able to participate in this study cohort if they also have heart failure. Participants will take part in the open-label, PK cohort for about 7 months.
