Research Excerpts

Overview

Darapladib is an oral, selective inhibitor of the Lp-PLA2 enzyme. It has been shown to reduce lysophosphatidylcholine content and expression of multiple genes associated with macrophage and T-lymphocyte functioning.

Treatment

Darapladib treatment significantly reduced (p<0.05) foam cells number as well as iNOS expression in aorta in rats with T2DM after both treatment times. Treatment was associated with a decrease in necrotic core, but was not associated with decreases in percentage atheroma volume.

Mean sCD40L Levels as Circulating Biomarkers Associated With Inflammatory Burden at Week 26 and Week 52

Blood was collected at baseline, Week 4, 13, 26 and 52 for evaluation of biomarkers. Mean sCD40L levels as circulating biomarker associated with inflammatory burden at Week 26 and Week 52 were assessed and reported. sCD40L had a skewed distribution and values were log transformed before analysis. The statistics was calculated on the log transformed data and back transformed. The adjusted geometric means of sCD40L levels at Week 26 and 52 were reported. The levels were analyzed using ANCOVA, with ACS status, pooled country and treatment included as covariates. (NCT00268996)

Change From Baseline in Mean Plaque Area, Mean Vessel Area, and Mean Lumen Area as IVUS-Grey Scale Assessments at Week 52.

Change from baseline in was mean plaque area, mean vessel area, and mean lumen area were derived from IVUS system at each IVUS grey scale assessment recorded. The baseline value for each participant was defined as the last value prior to the first dose of study drug. Change from baseline was calculated as mean area of the parameter (plaque/vessel/lumen) at Week 52 minus baseline value. The data was reported based on observed cases. Data analyzed using ANCOVA, with ACS status, pooled country, baseline value, matched segment length and treatment included as covariates. (NCT00268996)

Mean Lipoprotein Phospholipase A2 (Lp-PLA2) Activity at the End of Week 26 and Week 52

Lp-PLA2 is a calcium-independent phospholipase A2 enzyme associated with low density lipoprotein (LDL) in plasma. Blood samples were collected at baseline and at Week 4, 13, 26, and 52 and Lp-PLA2 activity was determined. Percentage inhibition of Lp-PLA2 activity relative to baseline was calculated as, percent inhibition = ([baseline value - post baseline value] x 100) / baseline value.

Change From Baseline to Week 4 in Plasma Lipoprotein-associated Phospholipase A2 (Lp-PLA2) Activity

Blood sample for Lp-PLA2 activity was collected before administration of study medication on the sampling day. Participants were instructed to visit without meal and study medication in the morning. The study medication was administered with food following test. Baseline value was defined as the assessment done on Week 0 (Visit 2). Change from Baseline was calculated as the post-Baseline (Week 4) assessment value minus the Baseline assessment value. If either value was missing, then the change from Baseline was set to be missing. The natural logarithm (log) was used for transformation in Lp-PLA2 activity. In case of zero values, an offset of 0.0001 was added to the zero values to ensure that the log transformation was successfully applied. The log transformation was conducted on the original value and then taken the change from Baseline on that log original value, calculated as log (post-Baseline value [week 4]) minus log (Baseline value).

Timeframe: From randomization until the End-of-Treatment visit or the last date on which endpoints were able to be assessed (up to 3.80 years)

Number of Participants With First Occurrence of Any Event in the Composite of Total Coronary Events (CHD Death, Non-fatal MI, Hospitalization for Unstable Angina, or Any Coronary Revascularization Procedure) During the Time Period for FU of CV Events

CHD death, acute MI, and prior MI diagnosed post-randomization are defined in the primary endpoint (major coronary events). Hospitalization for unstable angina=one of the following, but not fulfilling the criteria for MI: ischemic discomfort at rest associated with electrocardiogram (ECG) changes leading to hospitalization; ischemic discomfort at rest regardless of ECG changes leading to hospitalization and revascularization during the same admission; ischemic discomfort at rest in hospital associated with ECG changes; ischemic discomfort at rest in hospital without ECG changes resulting in revascularization during the same admission. NOTE: The event was not considered to be unstable angina if, after invasive/non-invasive testing or other diagnostic testing, the discomfort was found not to be caused by myocardial ischemia. Coronary revascularization procedures exclude PCI planned prior to randomization but performed after randomization. (NCT01000727)
Timeframe: From randomization until the End-of-Treatment visit or the last date on which endpoints were able to be assessed (up to 3.80 years)

Number of Participants With First Occurrence of Any Event in the Composite of Major Coronary Events During the Time Period for Follow-up (FU) of Cardiovascular (CV) Event

Coronary heart disease (CHD) death=occurrence of a fatal myocardial infarction (MI), death caused by documented cardiac arrest, death resulting from heart failure in a participant with known CHD, death from other forms of acute/chronic CHD, unwitnessed death of unknown origin, or sudden death. Acute MI=evidence of myocardial necrosis in a clinical setting consistent with myocardial ischemia. Prior MI diagnosed post-randomization (e.g., silent MI)=the development of new pathological Q waves with/without symptoms OR imaging evidence of a region of loss of viable myocardium that is thinned and fails to contract, in the absence of a nonischemic cause (pre-event imaging data required for verification of new abnormality), OR pathological findings of a healed/healing MI. Urgent coronary revascularization (CR) for MI=ischemic discomfort at rest that prompted CR during the same hospitalization or resulted in hospital transfer for the purpose of CR. (NCT01000727)

Number of Participants With Urgent Coronary Revascularization for Myocardial Ischemia During the Time Period for Follow-up of Cardiovascular Events

Urgent coronary revascularization for myocardial ischemia is defined as ischemic discomfort at rest that prompts coronary revascularization (PCI or coronary artery bypass graft [CABG]) during the same hospitalization or resulting in hospital transfer for the purpose of coronary revascularization. PCI is defined as any attempt at revascularization even if not successful (e.g., angioplasty, atherectomy or stenting). (NCT01000727)
Timeframe: From randomization until the End-of-Treatment visit or the last date on which endpoints were able to be assessed (up to 3.80 years)

Percentage Change in Coronary Blood Flow (CBF)

The change in coronary blood flow was measured in response to maximal dose of acetylcholine administered intracoronary during an invasive coronary endothelial function assessment. Percentage change in coronary blood flow provides a measure of endothelium dependent microvascular function. (NCT01067339)
Timeframe: baseline, six months

Percentage Change in Coronary Artery Diameter

The change of coronary artery diameter was measured in response to a maximal dose of acetylcholine administered intracoronary during an invasive coronary endothelial function assessment. Percentage change in coronary artery diameter provides a measure of endothelium dependent epicardial function. (NCT01067339)
