7. For those patients with a history of clinical ASCVD, serum LDL-C ≥ 70 mg/dL at
screening (1 repeat lab is allowed)

8. For those patients without a history of clinical ASCVD, serum LDL-C ≥ 100 mg/dL at
screening (1 repeat lab is allowed)

9. Provide signed informed consent


Exclusion Criteria

2. Presence of any clinically significant uncontrolled endocrine disease known to
influence serum lipids or lipoproteins

3. Newly diagnosed diabetes (within 3 months prior to screening)

4. Use of thyroid medications (except for replacement therapy which has been stable for
at least 12 weeks before screening)

5. Laboratory findings during screening period (not including randomization labs):

1. Triglycerides > 400 mg/dL (> 4.52 mmol/L) for patients without a known history of
diabetes mellitus; OR Triglycerides > 300 mg/dL (> 3.39 mmol/L) for patients with
a known history of diabetes mellitus

2. Positive test for Hepatitis B surface antigen and/or Hepatitis C antibody
(associated with a positive HCV ribonucleic acid [RNA] polymerase chain reaction)

of childbearing potential

4. Estimated glomerular filtration rate < 30 mL/min/1.73 m^2

5. TSH > 1.5 x ULN

visit or time of randomization

7. History of heart failure (New York Heart Association [NYHA] Class III-IV) within 12
months before screening

8. History of MI, unstable angina leading to hospitalization, CABG surgery, PCI,
uncontrolled cardiac arrhythmia, carotid surgery or stenting, stroke, TIA, carotid
revascularization, endovascular procedure or surgical intervention for peripheral
vascular disease within 3 months prior screening

9. History of cancer within the past 5 years (except for adequately treated basal cell
skin cancer, squamous cell skin cancer, or in situ cervical cancer)

10. Having received LDL apheresis within 2 months before screening

11. Pregnant or breast-feeding women

12. Women of childbearing potential who are unwilling to practice a highly effective birth
control method

13. Sexually active men unwilling to use acceptable birth control.

Detailed Description

The primary objective of the study is to evaluate the reduction of LDL-C by evinacumab in comparison to placebo after 16 weeks in patients with primary hypercholesterolemia (HeFH, or non-HeFH with a history of clinical ASCVD) with persistent hypercholesterolemia despite receiving maximally-tolerated LMT. Persistent hypercholesterolemia is defined as LDL-C ≥70 mg/dL (1.81 mmol/L) for those patients with clinical ASCVD and LDL-C ≥100 mg/dL (2.59 mmol/L) for those patients without clinical ASCVD.
