Is this trial a fit for you?

Likely a good fit

Adults with symptomatic genetic or familial dilated cardiomyopathy who completed prior blinded treatment in related studies and meet safety criteria.

Probably not a fit

Patients with recent serious cardiovascular events or contraindications may not benefit from this treatment.

What this trial studies

This Phase 3 trial investigates the long-term safety and potential benefits of danicamtiv in adults who have symptomatic genetic or familial dilated cardiomyopathy. Participants will take danicamtiv twice daily for up to five years and undergo about 16 clinical visits with tests to monitor health and response. The study focuses on durability of treatment effects and appropriate chronic dosing over time. Enrollment requires prior participation in a related study and certain safety criteria, with exclusions including recent acute coronary events or recent heart failure hospitalization. Lead sponsor is Kardigan, Inc., with sites at University of Alabama Birmingham, Cedars-Sinai, and UCLA.

Why it matters

Potential benefit: If successful, participants may experience improved heart function and symptom relief from danicamtiv with long-term treatment.

How similar studies have gone: Prior related studies have explored similar long-term approaches, but data on danicamtiv in this specific genetic/familial DCM population remains development-stage.

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.
