This research aims to evaluate the safety and effects of the study medicine PF-07328948 for adults with heart failure. It focuses on how this medicine works compared to a placebo in people who are already using standard heart failure treatments that include sodium-glucose cotransporter 2 (SGLT2) inhibitors. The trial is a Phase 2 study designed to better understand if PF-07328948 is safe and effective for managing heart failure symptoms and improving patients' health. Participants will be randomly assigned to receive either placebo tablets or one of three doses of PF-07328948 (low, medium, or high dose). All medications are taken once daily by mouth for 36 weeks. The treatment period is followed by ongoing study visits to monitor participants. The study involves 15 visits over about 48 weeks, with 10 visits at the study site and 5 visits conducted remotely by phone. During the study, researchers will assess participants at the start and after 36 weeks by measuring clinical events, changes in the six-minute walk test distance, and changes in heart failure symptoms using the Kansas City Cardiomyopathy Questionnaire. Safety and treatment effects will be closely monitored through these visits and assessments throughout the study period.
