Symptomatic Genetic Dilated Cardiomyopathy (DCM)
Conditions
Brief summary
Danicamtiv is an investigational medication, which means it is still being studied and has not been approved. The purpose of this study is to learn how well danicamtiv works, how safe it is, how well people can take it when used in patients with genetic or familial dilated cardiomyopathy (DCM). There are currently no approved medicines made specifically to treat genetic or familial DCM.
Detailed description
The Sponsor is studying an investigational medication called danicamtiv to understand its long-term benefits and risks in patients with symptomatic genetic or familial DCM. This study will examine the durability of treatment effects with continued exposure and evaluate appropriateness of chronic dosing over time. Participants will: * Take the investigational medicine, danicamtiv, twice daily throughout the study, which is up to 5 years * Visit the clinic about 16 times for clinical evaluations and diagnostic tests
Interventions
Danicamtiv will be administered twice daily for up to 5 years

Study design
Intervention model description
Global, multicenter study of danicamtiv in participants with symptomatic genetic or familial DCM who previously completed Part 1 or Part 2 of DAN-301 study. Once eligibility is confirmed, participants will receive danicamtiv twice daily dosing.
Eligibility
Inclusion criteria
1. Completed 24 weeks of blinded study treatment (corresponding to the Week 26 Visit in DAN-301) and planned assessments in Part 1 or Part 2 of the DAN-301 study. 2. If sexually active, must use a highly effective birth control method from the Screening Visit through 3 months after the last dose. 3. Is able to understand and comply with the study procedures, understand the risks involved in the study, and provide written informed consent according to local and institutional guidelines before the first study-specific procedure.
Exclusion criteria
1. Acute coronary syndrome or hemodynamically significant epicardial coronary disease, or coronary revascularization (percutaneous coronary intervention \[PCI\] or coronary artery bypass graft \[CABG\]) performed within 90 days of DAN-302 Screening Visit. 2. Recent (\<90 days) hospitalization for heart failure (HF) or use of IV diuretic. 3. Other recent (\<90 days) cardiovascular events (e.g., cerebrovascular accident). 4. Hospitalization for sepsis or other systemic infections within 30 days of Screening. A systemic infection includes suspected or confirmed infection associated with fever, hemodynamic instability, bacteremia, or organ dysfunction typically requires urgent evaluation and/or acute care. 5. Any malignancy requiring treatment after enrollment in DAN-301 that could limit patient's survival.
