Study results and endpoints

In the 16-week Phase 2 trial, mosliciguat demonstrated a statistically significant 56% reduction in pulmonary vascular resistance compared to a placebo. This metric measures blood pressure and flow within the artery connecting the heart to the lungs. The study also met its key secondary endpoints. Patients treated with the drug showed a 35-meter improvement in six-minute walk distance compared to the placebo group, as well as a 53% reduction in NT-proBNP, which serves as a blood-based marker for heart failure.
