NCT05492500

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.

Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in Kansas City Cardiomyopathy Questionnaire (KCCQ)-23 - Clinical Summary Score (CSS) at Week 22: Cohort A, Ponsegromab 300 mg Versus Placebo

    KCCQ is a self-reported 23-item questionnaire that assessed health related quality of life (HRQL) in participants with heart failure (HF) over the past 2 weeks. KCCQ quantifies 7 domains: physical limitations (6 items), symptom stability (1 item), symptom frequency (4 items), symptom burden (3 items), self-efficacy (2 items), quality of life (3 items) and social limitations (4 items). Scores were generated for each domain and scaled from 0 (worst status) to 100 (best possible status). KCCQ total symptom score (TSS): mean of domains- symptom frequency and symptom burden; and was transformed to a single score which ranged from 0 (worst) to 100 (best possible status). KCCQ-23-CSS: mean of the TSS and physical limitation domain score; and was transformed to a single score which ranged from 0 (worst) to 100 (best possible status), where higher KCCQ-23-CSS signified better health status.

Masking Details
In the main cohort (Cohort A), Cohort C and Cohort D, investigators, sponsor, participants and other site staff will be blinded to participants' assigned study intervention, including the site staff assigned to prepare and administer the study intervention. Pharmacists and site personnel will be blinded to study intervention versus placebo within each study arm. The separate PK cohort (Cohort B) will be open-label and study treatment will be prepared and administered as per treatment assignment by qualified personnel. There is no blinding in the open-label, PK cohort (Cohort B).

Intervention Model
PARALLEL
Model Details: In the main cohort (Cohort A), ponsegromab will be administered at low, medium and high doses every 4 weeks by subcutaneous injections for a total of 6 doses. Participants will be randomized to 1 of the 3 doses of ponsegromab or placebo. In optional Cohort C, ponsegromab will be administered at low doses every 4 weeks by subcutaneous injections for a total of 6 doses. Participants will be randomized to the low dose of ponsegromab or placebo. In optional Cohort D, ponsegromab will be administered at high doses every 4 weeks by subcutaneous injections for a total of 6 doses. Participants will be randomized to the high dose of ponsegromab or placebo. In a separate open-label, PK cohort (Cohort B), ponsegromab will be administered at low, medium and high doses every 4 weeks by subcutaneous injections for a total of 4 doses. Participants will be randomized to 1 of the 3 doses of ponsegromab. There is no placebo in the open-label, PK cohort.
