Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Documented diagnosis of heart failure (HF) based on medical records.
  • Left ventricular ejection fraction (LVEF) ≥ 35% and \< 50% at Screening, or documented within the 3 months before Screening, measured by transthoracic echocardiogram (TTE) or cardiac magnetic resonance imaging (MRI).
  • New York Heart Association (NYHA) HF Class I or II.
  • On a stable regimen of cardiovascular medication(s) for a duration of at least 4 weeks before Screening.

You may not qualify if:

  • Hospitalized for cardiovascular causes within 3 months before Screening.
  • Symptoms of angina pectoris at Screening.
  • History of sustained ventricular tachycardia or atrial fibrillation/atrial flutter with a ventricular response ≥ 110 beats per minute (bpm) at the time of Screening.
  • History of hypersensitivity to any components of the investigational product (IP).
  • Participant has received or is expected to receive a COVID-19 vaccination within 7 days of the planned date of IP administration.
  • For SAD cohort participants to be rolled over into the MAD stage, have experienced a dose-limiting toxicity (DLT) in a SAD cohort.
  • Participation in another clinical study of another IP within 30 days before Screening or within 5 terminal elimination half-lives of the IP, whichever is longer.
  • Any other clinically significant medical condition that, in the Investigator's opinion, could interfere with the interpretation of study results or limit the participant's participation in the study, including poorly controlled diabetes mellitus.
