A Study of Ponsegromab in People With Heart Failure

The primary purpose of this study is to assess the effect of repeated subcutaneous administration of ponsegromab (PF-06946860) compared to placebo on frequency, severity, and burden of symptoms as well as physical limitations in participants with heart failure and different ranges of circulating GDF-15 concentrations. The study will also assess the safety, tolerability, PK, PD, and immunogenicity of ponsegromab. A separate, open-label, PK cohort, with more frequent PK and GDF-15 collection after single and multiple subcutaneous administration of ponsegromab (PF-06946860), will be enrolled at certain sites to facilitate a more comprehensive assessment of PK characteristics and PK/PD relationship for GDF-15 in participants with heart failure and elevated circulating GDF-15 concentrations.
