Vericiguat for the Inhibition of Calcific Aortic Valve Stenosis Progression

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.

A Study to Evaluate the Efficacy and Safety of DA-1229 (Evogliptin) in Patient's Calcific Aortic Valve Disease With Mild to Moderate Aortic Stenosis (EVOID-AS)

This is an adaptive Phase 2/3 multicenter, double-blind, placebo-controlled, randomized, parallel, 2 arm study to evaluate the efficacy and safety of DA-1229 compared to placebo in patients with calcific aortic valve disease with mild to moderate aortic stenosis. There are 2 arms in this study to which patients will be randomized in a ratio of 1:1 to receive the DA-1229 or placebo orally once daily for a period of 104 weeks. The 2 arms are: placebo and DA-1229 10 mg Group. The study will have three phases: Screening Period (up to 4 weeks), Treatment Period (104 weeks), and Follow-Up Period (2-4 weeks). Total Study Duration is112 Weeks.

Exploration of Manidipine to Reverse Aortic Valve Calcification

This is a prospective, randomized, comparative, clinical trial conducted by Wuhan Union Hospital that aims to evaluate the efficacy and safety of manidipine compared to placebo in patients with calcific aortic valve disease with mild aortic valve stenosis.
