Research on Nicorandil Treatment of Patients Diagnosed as CHD (Coronary Heart Disease) With Stable Angina (SIGMART)
March 15, 2016 updated by: Merck KGaA, Darmstadt, Germany
A Prospective, Multi-center, Random, Open-label Research on Nicorandil Treatment of Patients Diagnosed as CHD (Coronary Heart Disease) With Stable Angina
This study of 402 cases of stable angina subjects who were diagnosed as Coronary Heart Disease (CHD) is a randomized, blank controlled, multi-center clinical study.
Subjects who are taking standard treatment with stable symptoms will receive a 24-hour ambulatory electrocardiogram (ECG) (Holter) examination.
They will be randomly divided into two groups.
The nicorandil group will receive nicorandil 5 milligram (mg) (3 times a day = tid) on top of the standard treatment for 12 weeks, while the control group will stay on standard treatment.
Nitrates and beta blockers need to be maintained on a stable dose.
Other drugs that do not affect the primary endpoint may be adjusted per investigators decision.

Intervention / Treatment |
---|---|
Experimental: Standard treatment plus nicorandil
The subjects will receive nicorandil 5 milligram (mg ) tablet orally three times daily for a period of 12 weeks along with one of the standard antianginal therapies (such as aspirin, beta-blockers, lipid lowering statins and angiotensin-converting enzyme inhibitors [(ACEIs] as permitted by disease condition /as per standard local practices/prescribed per discretion of investigators).

The subjects will receive Nicorandil 5 mg tablet orally three times daily for a period of 12 weeks along with the standard treatment.
The subjects will receive one of the standard anti-anginal therapies which included but not limited to aspirin, ACEI, lipid lowering statins and beta blockers according to the recommendation of guidelines.
If the subject's condition permitted, they should take all these medicines.
However, the dose, route, frequency and duration were determined by investigators according to subject's specific condition.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Myocardial Ischemia Attacks in 24 Hours
Time Frame: At Week 12
|
Myocardial ischemia attack was evaluated by 24-hour Holter monitoring based on the following criteria: 0.08 seconds after the J point in electrocardiogram (ECG) or compared with baseline levels, ST-segment with horizontal or downward sloping down greater than or equal to (>=) 0.1 millivolts (mV), and lasted for >= 1 minute, and at least 1 minute of interval with another ischemic attack, as one array myocardial ischemia.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in Total Myocardial Ischemic Burden at Week 12
Time Frame: Baseline, Week 12
|
The total myocardial ischemic burden was defined as the product of the decrease, total array and total time of ST-segment in symptomatic and asymptomatic myocardial ischemia subjects within 24 hours.
|
Baseline, Week 12
|
Change From Baseline in Maximum ST-depression at Week 12
Time Frame: Baseline, Week 12
|
The maximum ST- depression was evaluated from sum of all leads for all the subjects with myocardial ischemia attack.
Absolute value of maximum ST-depression was used for calculation.
|
Baseline, Week 12
|
Change From Baseline in Longest Duration of ST Segment Depression at Week 12
Time Frame: Baseline, Week 12
|
The maximum ST- depression was evaluated from sum of all leads for all the subjects with myocardial ischemia attack.
The longest duration of ST segment depression of all leads for all the subjects with myocardial ischemia attack.
|
Baseline, Week 12
|
Percentage of Subjects Experienced Ischemic Heart Attack During the Six-minute Walk Test
Time Frame: At Week 12
|
The percentage of subjects who experienced ischemic heart attack during the Six-minute walk test (6-MWT) were evaluated.The 6-MWT was the distance that a subject could walk in 6 minutes.
Subjects were asked to perform the test at a pace that was comfortable to them, with as many breaks as they needed.
The 6-MWT was completed within 1-hour after wearing Holter.
|
At Week 12
|
Heart Rate Variability (HRV) Rate: Time Domain
Time Frame: At Week 12
|
HRV is the degree of fluctuation in the length of the intervals between heart beats.
All HRV parameters are calculated on 'normal-to-normal' (NN) inter-beat intervals (or NN intervals) caused by normal heart contractions.
Standard deviation of all NN intervals (SDNN) and Standard deviation of the averages of NN intervals (SDANN) are the two time domain methods used to determine heart rate variability.
Two variants of the SDNN, created by dividing the 24-hour monitoring period into 5-minute segments, are the SDNN index and the SDANN index.
The SDNN index is the mean of all the 5-minute standard deviations of NN (normal RR) intervals during the 24-hour period, while the SDANN index is the standard deviation of all the 5-minute NN interval means.

HRV is the degree of fluctuation in the length of the intervals between heart beats.

Time Frame: From the first dose of study drug administration up to 30 days after the last dose of study drug administration (up to 16 weeks )
|
An AE was defined as any new untoward medical occurrences/worsening of pre-existing medical condition without regard to possibility of causal relationship.
SAE was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect.
TEAEs were defined as the AEs that occurred between first dose of study drug and up to 30 days after last dose that were absent before treatment or that worsened relative to pretreatment state.
|
From the first dose of study drug administration up to 30 days after the last dose of study drug administration (up to 16 weeks )
|
Number of Subjects Who Showed Compliance to Nicorandil
Time Frame: Baseline up to 12 Weeks
|
Compliance percent (%) was calculated by using the formula: (actual total dose divided by planned total dose) multiplied by 100.
If subject compliance was less than 80% or greater than 120%, then that subject was considered as non compliant.
The compliance of subjects taking nicorandil was evaluated.
