About this study

This study will investigate the role of polygenic risk scores (PRS) in preventive health.

Read the detailed description

This study will investigate the role of polygenic risk scores (PRS) in preventive health. Specifically, the purpose of this study is to determine whether knowledge of the degree of coronary artery disease (CAD) genetic risk or glaucoma genetic risk, as measured and conveyed by a PRS, influences patient and physician decision-making as well as clinical outcomes during short-term (6-month / 2-year) and long-term (3-year / 5-year) follow-up. A CAD and glaucoma PRS will be calculated for all study participants, with participants randomized to receiving either their CAD or glaucoma PRS. This study design allows for causal attribution of preventive actions and clinical outcomes to the receipt and degree of genetic risk. The design is informed by a pilot (MyGeneRank) and phase 1 (PEPRS first phase) study, with the key extensions being the addition of randomization and increasing the study population size to power causal association with long-term, hard clinical outcomes.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Composite MACE in intermediate to high clinical risk population

    Incident MACE. Binary outcome measured at 5-years post-enrollment by EHR analysis. An interim analysis will be performed at 3-years. MACE is defined as arterial revascularization or hospitalization for unstable angina, myocardial infarction, stroke, or death from cardiovascular causes. The rate of incident MACE will be compared across CAD vs glaucoma arms overall in individuals achieving a baseline PCE≥7.5%.

    Measured: 5 years post enrollment

Secondary outcomes (9)
  1. Composite MACE in high PRS

    Incident MACE. Binary outcome measured at 3- and 5-years post-enrollment by EHR analysis. The rate of incident MACE will be compared across high CAD PRS individuals receiving vs blinded to their genetic risk in individuals achieving a baseline PCE≥5%.

    Measured: 5 years post enrollment

  2. MACE Components

    Incident MACE components (arterial revascularization or hospitalization for unstable angina, myocardial infarction, stroke, or death from cardiovascular causes). Binary outcomes measured at 3- and 5-years post-enrollment by EHR analysis. The rate of each incident MACE component will be compared across CAD vs glaucoma arms overall in individuals achieving a baseline PCE≥7.5%.

    Measured: 5 years post enrollment

  3. Treated Glaucoma

    Incident glaucoma diagnosis with initiation of treatment. Binary outcome measured at 3- and 5-years post-enrollment by EHR analysis. Incident treated glaucoma is defined as any individual with a claim for ophthalmic surgery (laser trabeculoplasty, laser peripheral iridotomy, cycloablation) or a prescription ophthalmic solution with one or a combination of the following active ingredients: prostaglandin analogs (tafluprost, bimatoprost, latanoprostene, travaprost, latanoprost), beta blockers (timolol, levobunolol, metipranolol, betaxolol, carteolol), alpha agonists (brimonidine, apraclonidine), cholinergic agonists (pilocarpine, carbachol), carbonic anhydrase inhibitors (methazolamide, dorzolamide, brinzolamide), and/or rho kinase inhibitor (netarsudil). The rate and age of incident glaucoma diagnosis with treatment will be compared across CAD and glaucoma arms overall, as well as across high glaucoma PRS individuals receiving vs blinded to their genetic risk.

    Measured: 5 years post enrollment

  4. LDL-C lowering

    Adequate LDL-C lowering. Binary outcome measured at 2-, 3-, and 5-years post enrollment by EHR entry. Adequate LDL-C lowering is defined as 30% or more reduction from baseline study measured LDL-C. The rate of adequate LDL-C lowering will be compared across CAD vs glaucoma arms overall, across high CAD PRS individuals receiving vs blinded to their genetic risk, and in association with high vs low CAD PRS in individuals receiving vs blinded to their genetic risk. Within these groups, the rate of adequate LDL-C lowering will be determined in the total population, as well as subgroups stratified by baseline PCE status. PCE strata are: <5%, 5%≤PCE<7.5%, and ≥7.5%.

    Measured: 5 years post enrollment

  5. Statin or other lipid lowering therapy initiation or intensification

    New or intensified prescriptions for statins or other LDL lowering therapy. Binary outcome measured at 6-months post-enrollment by survey-based self-report and EHR analysis. A prescription is considered new if no equivalent EHR entry exists 1-year prior to enrollment. A statin prescription is considered intensified if it changes intensity tiers (high-, moderate-, and low-intensity) as described in the 2013 ACC/AHA Guidelines on the Treatment of Blood Cholesterol12. The rate of lipid lowering therapy initiation and intensification will be compared across high CAD PRS individuals receiving vs blinded to their genetic risk, and in association with high vs low CAD PRS in individuals receiving vs blinded to their genetic risk. Within these groups, the rate of statin or other lipid lowering therapy initiation or intensification will be determined in the total population, as well as subgroups stratified by baseline PCE status. PCE strata are: <5%, 5%≤PCE<7.5%, and ≥7.5%.

    Measured: 1 year post enrollment

  6. Statin or other lipid lowering therapy persistence

    Statin or other lipid lowering therapy prescription renewal. Binary outcome measured at 2-years post-enrollment by EHR analysis. Statin persistence is defined as prescription renewal within 60 days of the end of the duration of an index statin prescription made after study enrollment13. The rate of lipid lowering therapy persistence will be compared across high CAD PRS individuals receiving vs blinded to their genetic risk, and in association with high vs low CAD PRS in individuals receiving vs blinded to their genetic risk. Within these groups, the rate of statin or other lipid lowering therapy persistence will be determined in the total population, as well as subgroups stratified by baseline PCE status. PCE strata are: <5%, 5%≤PCE<7.5%, and ≥7.5%.

    Measured: 2 years post enrollment

  7. Statin or other lipid lowering therapy adherence

    Statin or other lipid lowering therapy prescription possession. Binary outcome measured at 2-years post-enrollment by EHR entry. Statin adherence is defined as prescription coverage of no less than 80% of the days between the index statin prescription and the end of the 2-year follow-up period13. The rate of lipid lowering therapy adherence will be compared across high CAD PRS individuals receiving vs blinded to their genetic risk, and in association with high vs low CAD PRS in individuals receiving vs blinded to their genetic risk. Within these groups, the rate of statin or other lipid lowering therapy adherence will be determined in the total population, as well as subgroups stratified by baseline PCE status. PCE strata are: <5%, 5%≤PCE<7.5%, and ≥7.5%.

    Measured: 2 years post enrollment

  8. Glaucoma screening

    Adoption of glaucoma screening. Binary outcome measured at 6-months and 2-years post-enrollment by self-report electronic survey. An analysis using claims and EHR data will be conducted if the degree of missingness data (due to, e.g. uncaptured optometrist visits) is no greater than 20%. The rate of glaucoma screening will be compared across high glaucoma PRS individuals receiving vs blinded to their genetic risk, and in association with high vs normal glaucoma PRS in individuals receiving vs blinded to their genetic risk.

    Measured: 2 years post enrollment

  9. Physician Utility

    Physician confidence, perceived utility, and actions attributable to genomic testing. Measured at 6-months and 1-year by survey-based self-report. Physician utility is characterized using a survey. Analyses are descriptive.

    Measured: 1 year
