Phase IIb Safety and Efficacy Study of Four Dose Regimens of BAY1021189 in Patients With Heart Failure With Reduced Ejection Fraction Suffering From Worsening Chronic Heart Failure (SOCRATES-REDUCED)

Study Overview

Brief Summary
-----------------
Objective of the study is to find the optimal dose of the once daily oral soluble guanylate cyclase stimulator (sGC) BAY1021189 for Phase III that can be given in addition to standard therapy for heart failure with reduced ejection fraction (HFrEF).
