Brief summary: 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.

Withdrawal Criteria:

A subject who is randomized into the study, but who does not complete the study will be considered prematurely discontinued.

At any point during the study all subjects have the right to withdraw without prejudice to future care. Documentation to whether or not each subject completed the clinical study will be recorded. If for any subject, study treatment was discontinued, the reason(s) will be documented.

The Investigator can discontinue a subject at any time if in their clinical judgment it is considered to be medically necessary. Investigators considering discontinuing study treatment should contact the medical monitor prior to such discontinuation. Subjects who have study treatment discontinued will continue to be followed per protocol (i.e., to complete EOT Visit and Visit 11 assessments), whenever possible. Subjects who have study treatment discontinued due to a serious adverse event will be followed until resolution or stabilization of the event. Reasons for subject withdrawal/discontinuation may constitute one of the following:

* Voluntary withdrawal of his/her informed consent
* Administration of any prohibited medication unless otherwise approved by the investigator(s)
* Serious adverse event or adverse drug reaction that causes withdrawal from the study, such as development of acute pancreatitis investigator(s)
* Any evidence of pancreatic inflammation on pancreatic imaging (CT Scan or Magnetic resonance cholangiopancreatography (MRCP) or Ultrasound)
* Severe breach against this protocol such as breach of any inclusion or exclusion criteria
* When Investigator judges aortic valve surgery or procedure is necessary due to progression of disease as per the Critical Pathways presented in American and European Society of Cardiology
* Failure to trace the subject - out of contact, etc. - for follow-up observation
* Pregnancy
* Discontinuation of study by the Sponsor
