Brief Summary:
cvMOBIUS is a North American registry of patients with ASCVD aimed at understanding patterns of care in ASCVD while evaluating the real world effectiveness of PCSK9 inhibitors.

Condition or disease
ASCVD

Detailed Description:
The purpose of this registry is to evaluate the effectiveness of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors (PCSK9i) to reduce cardiovascular events among subjects presenting with a recent atherosclerotic cardiovascular disease (ASCVD) event in real-world practice. A total of 8500 patients with a recent cardiovascular event who are likely to be eligible for non-statin lipid lowering therapy will be enrolled and followed prospectively for five years. In addition, the study will assess longitudinal patterns of lipid control, clinical outcomes, and LLT including statins, ezetimibe, and PCSK9 inhibitors in adults with an ASCVD event and/or revascularization. This study will also compare the clinical characteristics and outcomes of subjects enrolled in both arms of the registry to understand the strengths and limitations of data harvested directly from electronic health record (EHR) systems as compared with prospectively collected information.

Group/Cohort
Consented Arm
Subjects with a recent (within 18 months) hospitalization for myocardial infarction, unstable angina, ischemic stroke, or critical limb ischemia, and subjects undergoing coronary, peripheral, or carotid revascularization, including surgical and percutaneous revascularization, with an LDL-C greater than or equal to 70 mg/dL who may be eligible for PCSK9 inhibitor therapy.
Electronic Health Record (EHR) arm
Subjects with an inpatient or outpatient diagnosis of clinical ASCVD within the prior 12 months including coronary heart disease, ischemic cerebrovascular disease, atherosclerotic peripheral arterial disease, or prior coronary or peripheral or carotid revascularization.


Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Incident event rate for the composite of all-cause mortality, non-fatal myocardial infarction (MI), and non-fatal ischemic stroke (IS). [ Time Frame: Through study completion, a minimum of 4.5 years and maximum of 5 years ]
    Number of incident all-cause deaths, non-fatal MI, and non-fatal IS events (whichever occurs first) divided by the person-time at risk


Secondary Outcome Measures :
  1. Incident event rate for all-cause mortality [ Time Frame: Through study completion, a minimum of 4.5 years and maximum of 5 years ]
    Number of all-cause deaths divided by the person-time at risk

  2. Incident event rate for non-fatal MI [ Time Frame: Through study completion, a minimum of 4.5 years and maximum of 5 years ]
    Number of incident non-fatal MI events divided by the person-time at risk

  3. Incident event rate for non-fatal IS [ Time Frame: Through study completion, a minimum of 4.5 years and maximum of 5 years ]
    Number incident non-fatal IS events divided by the person-time at risk

  4. Incident rate of coronary or peripheral or carotid revascularication procedures [ Time Frame: Through study completion, a minimum of 4.5 years and maximum of 5 years ]
    Number of incident coronary or peripherial or carotid revascularization procedures

  5. Incident event rate for major adverse limb events (MALE) including amputation [ Time Frame: Through study completion, a minimum of 4.5 years and maximum of 5 years ]
    Number of incident MALE events divided by the person-time at risk. MALE is defined as the composite of ALI, major amputation (above the knee or below the knee, excluding forefoot or toe), or urgent revascularization (thrombolysis or urgent vascular intervention for ischemia).

  6. Incident event rate for cardiovascular death [ Time Frame: Through study completion, a minimum of 4.5 years and maximum of 5 years ]
    Number of cardiovascular deaths divided by the person-time at risk

  7. Incident event rate for transient ischemic attack (TIA) [ Time Frame: Through study completion, a minimum of 4.5 years and maximum of 5 years ]
    Number of incident TIA events divided by the person-time at risk

  8. Incident event rate for unstable angina (UA) [ Time Frame: Through study completion, a minimum of 4.5 years and maximum of 5 years ]
    Number of incident UA events divided by the person-time at risk

  9. Longitudinal patterns of lipid control, use of and persistence with lipid lowering therapies (LLT) including statins, ezetimibe, and PCSK9 inhibitors [ Time Frame: Through study completion, a minimum of 4.5 years and maximum of 5 years ]
    Describe patterns of lipid control and LLT's over time

  10. The strengths and limitations of data harvested directly from electronic health record (EHR) systems as compared with prospectively collected information [ Time Frame: Through study completion, a minimum of 4.5 years and maximum of 5 years ]
    Describe and compare clinical characteristics, ASCVD events, patterns of lipid control, and use of LLT's assessed via prospective data collection to those captured directly via an EHR data harvest.

Study Population

Subjects with a recent ASCVD event or coronary, peripherial or carotid revascularization (in the prior 18 months).

Criteria

Inclusion Criteria:
