RecruitingPhase 1

Sponsor: Novartis Pharmaceuticals

Conditions: Heart Failure With Reduced Ejection Fraction

Interventions: HJB647 low dose, HJB647 high dose, Placebo

Countries: United States, Canada

The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of HJB647 at two different doses in participants with chronic stable heart failure with reduced or mildly reduced ejection fraction (HFrEF/HFmrEF).
