A Phase 2b/3, Adaptive, Randomized, Double-blind, Placebo-controlled, Multicenter Study to Assess the Efficacy and Safety of Danicamtiv in Participants With Symptomatic Genetic and Familial Dilated Cardiomyopathy

The Sponsor is studying an investigational medication called danicamtiv to determine if it can help people with genetic and familial dilated cardiomyopathy (DCM). Investigational means that the safety and effectiveness of danicamtiv have not been established. Currently, there are no approved drugs that are designed specifically to treat genetic or familial DCM.

The purpose of this study is to evaluate how well danicamtiv works compared to a placebo (sugar pill that looks like danicamtiv pill but does not contain any danicamtiv) and see how safe it is for people with genetic and familial DCM. In DCM, the heart muscle weakens and enlarges, making it harder for the heart to pump blood; this can happen for different reasons. Some people have DCM because of a change in a gene (called genetic DCM). Others may have DCM that runs in their family, even if no specific gene change is found (called familial DCM).

The main goals of the study are:

* To assess the effect of danicamtiv on cardiac function using echocardiogram. * To evaluate the impact of danicamtiv on exercise capacity * To evaluate the safety and tolerability of danicamtiv

Participants will:

* Take danicamtiv or placebo every day for approximately 6 months * Visit the clinic about 12 times for initial evaluation, checkups, tests and follow up

Bevonási feltételek: Has a diagnosis of DCM due to probable disease-causing variants of MYH7, TTN, or other identified genetic DCM variants, or with familial DCM; Has New York Heart Association (NYHA) Class II-IV at Screening with stable symptoms for ≥1 month; Has at least mild left ventricular enlargement (LVE) and has adequate acoustic windows to enable accurate TTEs according to the Echocardiography Core Laboratory; Has a LVEF of ≤45%; Is on stable doses of maximally tolerated standard-of-care heart failure (HF) therapies reflecting current guidelines for at least 4 weeks prior to the first visit; Has DCM not attributed to substance abuse, amyloidosis, sarcoidosis, or any other secondary form of cardiomyopathy per the Investigator; Can perform an upright cardiopulmonary exercise training (CPET) with a peak oxygen uptake (pV̇O2) of 80% or less of predicted for a healthy individual and respiratory exchange ratio (RER) of ≥1.05.

Kizáró feltételek: Has heart failure with reduced ejection (HFrEF) caused primarily by ischemic heart disease, chronic valvulopathy, or another condition, as determined by the Investigator; Recent (<90 days) clinically significant cardiac events, including acute coronary syndrome, hemodynamically significant epicardial coronary disease (per Investigator), coronary revascularization (percutaneous coronary intervention [PCI] or coronary artery bypass graft [CABG]), or hospitalization for heart failure/intravenous (IV) diuretic use; Presence of disqualifying cardiac rhythms that might interfere with reliable echocardiographic measurements of left ventricle (LV) function, as determined by the Investigator including: (a) inadequately rate-controlled atrial fibrillation, (b) ectopic beats (atrial, junctional or ventricular) of sufficient frequency (e.g. > 10% of total beats) that the participant's cardiac rhythm is irregular potentially interfering with reliable echocardiographic measurements of LV function; History of malignancy of any type within 5 years prior to Screening; History or evidence of any other clinically significant disorder, condition, or disease that, in the opinion of the Investigator or Sponsor, would pose a risk to participant safety or interfere with the study evaluation; History of heart transplantation or anticipated heart transplantation in the next 6 months; Ongoing or anticipated advanced cardiac interventions, including chronic IV inotropic therapy, planned cardiac resynchronization therapy (CRT) or major surgery, or current/anticipated ventricular assist device placement within 6 months; Severe renal insufficiency (defined at the time of Screening as current estimated glomerular filtration rate [eGFR] <15 mL/min/1.73m2 by simplified Modification of Diet in Renal Disease equation [sMDRD]); Clinically significant laboratory abnormalities at Screening; Unstable or untreated severe ventricular arrythmia (eg, ventricular tachycardia or ventricular fibrillation).
