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.

Detailed description

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.

Masking description

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 description

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.

The short form (SF) 7A consisted of 7 items that study participants rated from 1: "Never" to 5: "Always". A global raw score ranged from 7 to 35 was calculated and translated into a T-score with minimum of 29.4 and maximum of 83.2 (mean = 50, a standard deviation \[SD\] = 10) using the applicable score conversion provided in the PROMIS user's manual. Higher scores indicated more fatigue.

An AE was considered a TEAE if the event started during the effective duration of treatment. TESAE was a TEAE which met the definition of SAE viz. any untoward medical occurrence at any dose that resulted in death; was life-threatening; required inpatient hospitalization or prolongation of existing hospitalization; resulted in persistent or significant disability/incapacity; was a congenital anomaly/birth defect or was considered an important medical event.
