A Study to Evaluate the Effectiveness and Safety of DA-1229 (Evogliptin) in Delaying Progression of Mild or Moderate Calcific Aortic Stenosis (EVOID-AS trial)


About this study

The purpose of this study is to evaluate the effectiveness and safety of DA-1229 compared to placebo in patients with calcific aortic valve disease with mild to moderate aortic stenosis. There are 3 arms in this study to which patients will be randomized in a ratio of 1:1:1 to receive the DA-1229 or placebo orally once daily for a period of 104 weeks. The 3 arms are: placebo, DA-1229 5mg Group, 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 is 112 Weeks.
