New drug shows promise for repairing damaged hearts in stable heart failure patients
NCT ID NCT07405944
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether the drug vericiguat can help repair the hearts of adults with stable heart failure with reduced ejection fraction (HFrEF). Researchers will compare people taking vericiguat plus standard care to those on standard care alone, measuring changes in heart structure and function over 12 months. The study involves 60 participants and includes blood tests, heart scans, and glucose tests to understand how the drug works.

Inclusion Criteria: * Written informed consent from an adult patient (≥ 18 years old) to participate in the clinical study, * Stable HFrEF defined as no heart failure worsening in the 6 months before randomization that required hospitalization or outpatient diuretic treatment, * Confirmed diagnosis of chronic heart failure with reduced ejection fraction (LVEF ≤ 40%, confirmed by echocardiography) within 12 months before randomization, * Stable GDMT for HFrEF for at least 3 months prior to randomisation. Exclusion Criteria: * Systolic blood pressure \< 100 mmHg or symptomatic hypotension, * Current or planned use of long-acting nitrates, soluble guanylate cyclase stimulators, or phosphodiesterase type V inhibitors, * Known allergy/hypersensitivity to soluble guanylate cyclase stimulators, * Awaiting heart transplantation or dependence on continuous inotropic therapy * Cardiac amyloidosis, sarcoidosis, myocarditis, stress cardiomyopathy, or tachycardic cardiomyopathy, * Acute coronary syndrome, coronary artery bypass grafting, or percutaneous coronary intervention in the past three months before randomisation, * Long-term mechanical circulatory support of the left ventricle, * Active infection, * Chronic kidney disease stage 4 or 5, and * Advanced liver failure classified as Child-Pugh B or C.
