A Trial of CRD-4730 in HFrEF
Recruiting now · Phase 2 · Has a placebo group
Conditions studied: Heart Failure With Reduced Ejection Fraction (HFrEF)
In brief
CRD-4730 is a calcium/calmodulin-dependent protein kinase II (CaMKII) inhibitor. The CALIBRATE-HF trial is a Phase 2, global, multi-center, randomized, double-blind, parallel-group, placebo-controlled trial. The trial will evaluate the efficacy, safety, and tolerability of CRD-4730 in addition to guideline directed medical therapy in participants with heart failure with reduced ejection fraction (HFrEF). Participants will be randomized to 1 of 4 study groups and receive investigational study drug or placebo twice daily (BID) for 24 weeks of treatment.

You may qualify if…
- Adult male or female patient ≥ 18 years of age and ≤ 85 years of age at the time of screening.
- Has a medical history supporting a diagnosis of clinical chronic heart failure (HF) syndrome with a duration of at least 8 weeks prior to the time of screening and current NYHA functional class II to III (based on investigator's assessment).
- Has left ventricular ejection fraction ≤ 40% by a centrally read transthoracic echocardiogram performed during screening.
- Has NT-proBNP level ≥ 600 pg/mL (70.8 pmol/L) at the time of screening. Patients in atrial fibrillation or flutter at the time of screening are required to have an NT-proBNP level of ≥ 900 pg/mL (106.4 pmol/L).

You may not qualify if…
- Has evidence of recent HF exacerbation defined by hospitalization or requirement for IV or SQ diuretics within 4 weeks of the time of screening or during the Screening Period.
- Has a requirement for routine, scheduled outpatient IV infusions for HF (ie, inotropes, vasodilators, or diuretics) or routinely scheduled ultrafiltration.
- Has acute coronary syndrome, unstable angina, persistent angina at rest, stroke, transient ischemic attack, cardiac, carotid or other major cardiovascular surgery, cardiac valve repair (surgical or nonsurgical) or surgical replacement, or carotid angioplasty within 8 weeks prior to screening or during the Screening Period.
- Has clinical suspicion of infiltrative cardiomyopathy (eg, 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.
- NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.
