The Precision CAD Trial
Use of Biomarker Risk Score to Optimize Therapy in Patients With Coronary Artery Disease: The Precision CAD Trial
Study Overview

Intervention / Treatment
Detailed Description
People with Coronary Artery Disease (CAD) have narrow or blocked arteries that supply blood to the heart. Reduced blood flow to the heart muscle from CAD can cause chest pain or aching, especially with exercise or activity. CAD can lead to weakening of the heart muscle or heart failure, and a higher risk of heart attack or death. Certain proteins in the blood, known as biomarkers, can be found in people with CAD. Higher levels of these biomarkers are associated with a greater risk of complications from CAD. The purpose of this study is to see if a customized treatment based on biomarkers will reduce the biomarker levels and lead to lower risk of complications from CAD.
Participants with high biomarker levels will be randomly assigned (like flipping a coin) to either the treatment group or usual care. Both groups will have physical exams, blood tests, and answer questionnaires. Participants in the treatment group will have their medications adjusted based on their biomarker levels. They will also be asked to make lifestyle changes like diet, exercise, and quitting smoking. Participants in the usual care group will receive the standard of care prescribed by their doctor.
This study will take place in research rooms at Emory University Hospital and the Woodruff Memorial Research Building.
Participants will be paid for being in the study.
Participants will be recruited from Emory Healthcare outpatient cardiology clinics and cath labs. Participants will be identified through the medical record and by their doctors. Written consent will be obtained from Participants before they can join the study.
Study data and blood samples will be collected and banked for possible research in the future. These may also be shared with other researchers including researchers outside of Emory.
This study will advance scientific knowledge and benefit human health by giving us more treatment options for CAD.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Optimization Group
Participants with CAD and a BRS greater than 0 who are randomized to the Optimization Group have treatment goals that include achieving LDL-C<70 mg/dL, hemoglobin A1c <7%, blood pressure <130/80 mmHg, smoking cessation, at least 30 minutes of moderate-intensity aerobic activity 5 days a week and weight loss to body mass index <30 kg/m2.
To achieve these goals, both pharmacological and lifestyle interventions will be considered and individualized for each patient.
|
|
Active Comparator: Usual Care Group
Participants with CAD and a BRS greater than 0 who are randomized to the usual care group will receive standard of care therapy prescribed by their primary care physician and/or cardiologist.
Patients and their physicians will be informed that their BRS is ≥1 and they have been randomized to the usual care group.
|
Participants will receive standard of care therapy prescribed by their primary care physician and/or cardiologist.
|
Other: Registry Group
Participants with BRS of 0 at baseline and after 3 months will undergo follow-up including measurements of BRS at the time-points specified for the randomized subjects and also for adverse events.
Laboratory results and questionnaire data will be obtained on the phone.
|
Participants with BRS of 0 will get measurements of BRS at the time-points specified for the randomized subjects and also for adverse events.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in plasma levels of hsCRP
Time Frame: Baseline, 1 year post intervention
|
Blood will be drawn for measurement of plasma levels of hsCRP to compare the optimization group and the usual care group.
|
Baseline, 1 year post intervention
|
Change in plasma levels of hs-cTnI
Time Frame: Baseline, 1 year post intervention
|
Blood will be drawn for measurement of plasma levels of hs-cTnI to compare the optimization group and the usual care group.
|
Baseline, 1 year post intervention
|
Change in plasma levels of BNP
Time Frame: Baseline, 1 year post intervention
|
Blood will be drawn for measurement of plasma levels of BNP to compare the optimization group and the usual care group.
|
Baseline, 1 year post intervention
|
Change in plasma levels of suPAR
Time Frame: Baseline, 1 year post intervention
|
Blood will be drawn for measurement of plasma levels of suPAR to compare the optimization group and the usual care group.
|
Baseline, 1 year post intervention
|
Change in Biomarker Risk Score (BRS)
Time Frame: Baseline, 1 year post intervention
|
The BRS score is a simple and manual observation of 4 biomarker results above a predetermined cutpoint that are run on FDA cleared and or CE marked platforms.
The BRS is calculated using levels of the 4 biomarkers.
Biomarker levels will be considered abnormal if hsCRP is >3 mg/L, suPAR (pg/mL) >2863 (males) and >4063 (women), hs-TnI (pg/mL)> 6.3 (men), >5.5 (women), and BNP (pg/mL) >122 (men), >184.1 (women).
The BRS ranges from 0 to 4 based on the number of biomarkers that are elevated above these cut off values.
Higher score correlates with worse outcome.
