Brief Summary

Calcific aortic valve stenosis (CAVS) is a condition in which the aortic valve progressively narrows and stiffens due to calcium deposition, eventually impairing blood flow from the heart to the body. No drug therapy has been proven to slow CAVS progression. Individuals with mild-to-moderate CAVS are managed with periodic monitoring until the stenosis becomes severe, at which point surgical or transcatheter valve replacement is the only treatment option. The goal of this clinical trial is to determine whether vericiguat, an oral soluble guanylate cyclase (sGC) stimulator, can slow the progression of mild-to-moderate CAVS. The primary questions this study aims to answer are: Does vericiguat slow the progression of aortic valve calcium accumulation, as measured by the change in aortic valve calcium score from baseline to 24 months, compared to placebo? The study will compare vericiguat against a placebo (an inactive pill that is identical in appearance but contains no active drug). Both participants and the research team will not know which treatment each participant is receiving throughout the study. Participants will: Take vericiguat or placebo orally once daily for 24 months; Begin treatment at 2.5 mg/day and undergo a stepwise dose increase every two weeks to a target dose of 10 mg/day, provided the drug is tolerated; Attend approximately 8 scheduled study visits over two years, during which they will undergo cardiac imaging examinations (transthoracic echocardiography and non-contrast cardiac CT), blood sample collection, physical assessment, and completion of standardized questionnaires on quality of life and heart failure symptoms; Undergo cardiac magnetic resonance imaging (MRI) at the beginning and end of the study, if there are no contraindications. Approximately 238 participants will be enrolled across roughly 19 hospitals in China.

Outcome Measures

Primary Outcomes (1)

  • Change in Aortic Valve Calcium (AVC) Score at 24 months

    Change in log-transformed aortic valve calcium score from baseline, measured by non-contrast electrocardiographic-gated cardiac CT (Agatston method). Higher scores mean worse outcome.

    At 24 months

Secondary Outcomes (17)

  • Hierarchical Composite Endpoint including Time to all-cause death, Time to aortic valve-related clinical events and Change in aortic valve calcification (AVC) score from baseline at 24 months (log-transformed).

    Up to 24 months

  • Change in Aortic Valve Calcium (AVC) Score at 12 Months

    At 12 months

  • Change from baseline in aortic valve calcium volume

    At 12 and 24 months

  • Change in Aortic Valve Peak Velocity

    At 6, 12, 18, and 24 months

  • Change in Aortic Valve Mean Pressure Gradient

    At 6, 12, 18, and 24 months

  • +12 more secondary outcomes

Other Outcomes (3)

  • Change in Coronary Artery Calcium Score at 12 and 24 Months

    At 12 and 24 months

  • Change in Cardiac Magnetic Resonance Parameters at 24 Months

    At 24 months

  • Change in Echocardiographic Left Ventricular Mass Index

    At 6, 12, 18, and 24 months

Study Arms (2)

Vericiguat

ACTIVE COMPARATOR

Vericiguat orally once daily.

Drug: Vericiguat (BAY1021189)

Placebo

PLACEBO COMPARATOR

Matching placebo tablets orally once daily

Drug: Placebo

Interventions

Vericiguat 2.5 mg orally once daily, titrated every 2 weeks (2.5 mg → 5 mg → 10 mg) to a target maintenance dose of 10 mg once daily. Total treatment duration: 24 months

Also known as: MK-1242, BAY 1021189
Vericiguat

Matching placebo tablets orally once daily, with a dose-titration schedule synchronized to the vericiguat arm to maintain blinding. Placebo tablets are identical to vericiguat tablets (2.5 mg, 5 mg, and 10 mg dose strengths) in size, shape, color, and texture. The same SBP-based dose-adjustment rules are applied. Total treatment duration: 24 months.
