Brief Summary
This is a study evaluating the effectiveness of CRD-740 in patients with either Heart Failure with Reduced Ejection Fraction (HFrEF) or Heart Failure with Preserved Ejection Fraction (HFpEF) after 12 weeks of treatment. The primary objective in Part A is to assess the effect of CRD-740 compared to placebo in plasma cGMP at Week 4 in HFrEF. Part B of the study was not conducted in favor of redesigned new studies.

Interventions
Eligibility Criteria
You may qualify if:
- Males or Females ≥18 years of age, at screening.
- Diagnosis of clinical heart failure syndrome, New York Heart Association functional class II - III for at least 6 months prior to screening
- For Part A:
- Ejection Fraction ≤40% by echocardiography at screening.
- NT-proBNP level ≥600 pg/ml at screening. Subjects with atrial fibrillation or flutter at screening are required to have an NT-proBNP level of ≥1000 pg/mL at screening.
- \. Stable doses of guideline-directed heart failure therapy for a minimum of 4 weeks prior to screening that has been individually optimized according to standard practice guidelines and no addition of guideline-directed heart failure therapy within 3 months of screening.
You may not qualify if:
- \. Recent HF exacerbation defined by hospitalization or requirement for intravenous diuretics within 60 days of screening.
- \. Subjects with planned interventions (e.g., percutaneous coronary intervention, devices) etc. occurring during their involvement in this study.
- \. Acute coronary syndrome, stroke, transient ischemic attack, cardiac, carotid or other major cardiovascular surgery or carotid angioplasty within 60 days of screening.
- \. Subjects with clinical suspicion of infiltrative cardiomyopathy (e.g., amyloid, sarcoid), hypertrophic cardiomyopathy (obstructive or non-obstructive), or HF secondary to severe valvular disease, active myocarditis, active pericarditis, or clinically significant congenital heart disease.
- \. Prior or planned orthotopic heart transplantation.
- \. Presence of or plan for mechanical circulatory support.
