The purpose of this study is to evaluate if ataciguat slows the progression of moderate calcific aortic valve stenosis in adults.
Inclusion: Adult male or female at least 50 years of age; Has moderate CAVS as defined by:; An AVA of ≥1.0 cm2 to ≤1.50 cm2; An AVC score between >300 to 1200 Agatston units (AU) for women and between >300 to 2000 AU for men; Has a left ventricular ejection fraction (EF) of ≥45% at the time of Screening as determined by the echocardiography Imaging Core Laboratory; For participants in CPET sub-study in Part A and all participants in Part B: If on beta blockade, the dose must be stable for at least 90 days prior to the Screening Visit with no anticipated changes during the study.
Exclusion: Anticipated or planned prior aortic valve replacement, repair, surgery, or intervention in the next 6 months; For participants in the CPET sub-study in Part A and all participants in Part B: Has any medical or physical condition that, in the Investigator's opinion, could lead to an inability to complete Protocol-required CPET procedures (eg, pulmonary disease, joint, leg, hip, back conditions that limit physical activity, or other absolute contraindications for CPET); Has suspected or known congenital aortic valve disease including bicuspid aortic valve; New York Heart Association (NYHA) Class IV heart failure symptoms and/or requires continuous inotropes; Has history of hypertrophic, genetic/familial cardiomyopathy or cardiomyopathy related to amyloid or sarcoid; Has untreated obstructive coronary artery disease or anticipating coronary stenting surgery; Has moderate, moderate-to-severe, or severe (Grade 2 or higher) mitral stenosis, mitral regurgitation, and/or aortic regurgitation; Abnormal electrocardiogram (ECG) results or long-standing persistent or permanent atrial fibrillation.
