Brief Summary
We hypothesized that fimasartan, a new generation ARBs, would improve exercise capacity and decrease the rate of progression of AS by modifying hemodynamic factors and reducing adverse LV remodeling favorably in patients with asymptomatic moderate to severe AS.

Outcome Measures
Primary Outcomes (1)
Change of VmaxO2 in Cardiopulmonary Exercise Test
Change of VmaxO2 from baseline to 1 year follow-up. VmaxO2 is defined as the highest oxygen uptake, averaged over 5 consecutive breaths, during the last minute of symptom-limited cardiopulmonary exercise test. For each patient, the change in VamxO2 is calculated as (VmaxO2 at 1 year follow-up) - (VmaxO2 at baseline)
Baseline and 1 year
Secondary Outcomes (13)
Change of peak aortic jet velocity in echocardiography
Baseline and 1 year
Change of mean pressure gradient across aortic valve
Baseline and 1 year
Diastolic function - LA area (cm2), E/E' value
Baseline and 1 year
Left ventricular mass index (LVMI)
Baseline and 1 year
Development of aortic stenosis symptoms
Baseline and 1 year
- +8 more secondary outcomes
Study Arms (2)
Placebo Arm
PLACEBO COMPARATORPlacebo: Capsule that is containing lactate hydrate, identically appearing with fimasartan will be administered to patient in placebo group, once daily. Same placebo drug which was used in phase 3 clinical trial of fimasartan will be provided by Boryoung Phamaceutical company. Dose titration will be done with same criteria of fimasartan group. 30mg form and 60 mg form of placebo will be identical in its morphology.
Fimasartan
ACTIVE COMPARATORFimasartan, Initial dose will be started with 30mg per day. At 12 months follow-up after the enrollment, dose titration up to 60 mg per day will be made with target blood pressure of 120/80. Dose escalization from 30mg/day to 60mg/day will be performed in the case of follow-up systolic blood pressure is over 120. If the follow-up systolic blood pressure is less than 120, initial dose of 30mg/day will be maintained throughout the study duration. If hypotension (BP \< 90/60) is developed, the study medication will be discontinued and the patient will be included safety outcome analysis and intention to treat analysis. Per protocol analysis will be also performed. The dose of placebo will be adjusted identically, according to the blood pressure criteria of fimasartan.
Interventions
Fimasartan, Initial dose will be started with 30mg per day. At 12 months follow-up after the enrollment, dose titration up to 60 mg per day will be made with target blood pressure of 120/80. Dose escalization from 30mg/day to 60mg/day will be performed in the case of follow-up systolic blood pressure is over 120. If the follow-up systolic blood pressure is less than 120, initial dose of 30mg/day will be maintained throughout the study duration. If hypotension (BP \< 90/60) is developed, the study medication will be discontinued and the patient will be included safety outcome analysis and intention to treat analysis. Per protocol analysis will be also performed. The dose of placebo will be adjusted identically, according to the blood pressure criteria of fimasartan.
Placebo was used in phase 3 clinical trial of fimasartan (NCT00922480, NCT01135212, and NCT01258673). The same placebo, which is manufactures at Boryoung pharmaceutical company, will be used in this trial. After enrollment and randomization, placebo will be administered one capsule once daily in placebo group.
Eligibility Criteria
You may qualify if:
- Male or female
- Age: 20-75 years
- Moderate to severe aortic stenosis defined as a continuous wave Doppler determined peak aortic valve jet velocity of 3.0 - 4.5 m/s, mean pressure gradient of 25 - 49 mmHg, or aortic valve area of 0.76 - 1.5 cm2.
- Asymptomatic aortic stenosis patients, Stationary or minimum dyspnea on exertion (NYHA Fc ≤ I or II) will be included.
- Patients who were prescribed ACEI or ARBs for treatment of hypertension will be enrolled after 2 weeks wash-out period.
- SBP 120-140 mmHg with or without medication regardless of presence of hypertension or not.
- Patients with BP \> 140/90 mmHg with or without medication will be included after their BP is controlled with anti-hypertensive medication other than ACEI/ARBs.
- Patients who are able to perform appropriate cardiopulmonary exercise test with treadmill.
- The patient agrees to the study protocol and the schedule of clinical, cardiopulmonary exercise test, and echocardiographic follow-up, and provides informed, written consent, as approved by the appropriate Institutional Review Board/Ethical Committee of the respective clinical site.
You may not qualify if:
- Symptomatic aortic stenosis: presence of exertional dyspnea (≥ NYHA Fc III), angina or syncope
- Very severe aortic stenosis regardless of presence of symptoms. It was defined as a critical stenosis in the aortic valve area ≤ 0.75 cm2 accompanied by a peak aortic jet velocity ≥4.5 m/s or a mean transaortic pressure gradient ≥50 mm Hg on Doppler echocardiography.
- Uncontrolled HTN (SBP \> 160 or DBP \>100) without ACEI or ARBs during 2-weeks wash out period in patients who were prescribed ACEI or ARBs for treatment of hypertension.
- Patients with known history of coronary artery disease including myocardial infarction, regardless of the treatment (medication only, percutaneous coronary intervention, or coronary artery bypass grafting).
- Planned cardiac surgery or planned major non-cardiac surgery within the study period.
- Stroke or resuscitated sudden death in the past 6 months.
- Chronic disease requiring treatment with oral, intravenous, or intra-articular corticosteroids (use of topical, or nasal corticosteroids is permissible).
- Untreated hyperthyroidism or hypothyroidism with TSH levels more than 2 times upper limit of normal.
- A diagnosis of cancer (other than superficial squamous or basal cell skin cancer) in the past 3 years or current treatment for the active cancer.
- Female of child-bearing potential who do not use adequate contraception and women who are pregnant or breast-feeding.
- Any clinically significant abnormality identified at the screening visit, physical examination, laboratory tests, or electrocardiogram which, in the judgment of the Investigator, would preclude safe completion of the study.
- Evidence of congestive heart failure, or left ventricular ejection fraction \< 50%.
- Significant renal disease manifested by serum creatinine \> 2.0mg/dL
- Hepatic disease or biliary tract obstruction, or significant hepatic enzyme elevation (ALT or AST \> 3 times upper limit of normal).
- Documented bilateral renal artery stenosis or known contraindication of ACEI or ARBs
- +5 more criteria
