Brief summary
A double-blind, randomized, placebo-controlled, parallel study to evaluate the effects of add-on RANCAD on exercise tolerance and angina frequency in patients with stable angina pectoris.
Detailed description
Primary objective is to to determine the effects of add-on RANCAD on exercise treadmill test (ETT) duration at trough plasma level of RANCAD level after 12-weeks therapy.

Inclusion criteria
1. Male or female patients aged ≥ 20 years old 2. A minimum 3-month history of stable angina 3. Patients with diagnosis of coronary artery disease (CAD) 4. Patients present with the symptoms of stable angina after withdrawn from other antianginal drugs and given the required background therapy for at least 7 days will be qualified for entering this study and performing 1st ETT qualifying test 5. Patients developed exercise-induced ECG ischemiai during two qualifying exercise treadmill testsii. The difference between twoiii tests should be ≤ 20% of the longer test or ≤ 1 minute i. Exercise-induced ECG ischemia is defined as the new development of horizontal or down-sloping ST-segment depression of ≥1mm at 60-80ms after the J point; if patients with baseline ST depression at rest (\<1mm), qualifying ST segment depression is defined as additional ST depression of at least 1 mm below the resting value ii. Exercise treadmill test (ETT) will be performed by Modified Bruce Protocol. iii. Two qualifying tests will be conducted 1 week apart, a 3rd ETT test will be performed ≤ 3 days when differences between previous two qualifying ETTs \>20% of the longer test or \>1 minute 6. Willing and able to provide a written informed consent
Exclusion criteria
1. Factors that might compromise ECG or ETT interpretation * Patients with resting ST-segment depression ≥ 1mm in any lead * Left bundle-branch block * Patients implanted with pacemaker * Patients under Digitalis therapy 2. Patients with family history of (or congenital) long QT syndrome 3. Patients with congenital heart disease 4. Patients with uncorrected valvular heart disease 5. Patients with unstable angina, or MI, or coronary revascularization procedure ≤ 2 months prior enter this study 6. Female who is pregnant/lactating or planning to be pregnant, or female of childbearing potential\* who is not using medically recognized method of contraception \*Other than those who have been surgically sterilized (defined as having undergone hysterectomy or bilateral oophorectomy or bilateral salpingectomy; tubal ligation alone is not considered sufficient) or one year post-menopausal. 7. Patients are under any one of the following conditions: * New York Heart Association (NYHA) Class III or Class IV congestive heart failure (CHF) * QTc \> 450 msec at screening * Active myocarditis, pericarditis, hypertrophic cardiomyopathy * Uncontrolled hypertension (defined as SBP \> 180 mmHg) Voltage criteria for left ventricular hypertrophy in the absence of repolarization abnormalities will not be
