Inclusion Criteria:

1. Acute type I (spontaneous) NSTEMI defined as chest pain (or equivalent) with an onset of symptoms within 12 hours of presentation, a duration of >15 minutes, and elevated cardiac troponin I levels, with or without electrocardiographic changes [with the exclusion of ST elevation];
2. On medical therapy with high intensity statin prior to admission (either atorvastatin 40-80 mg or rosuvastatin 20-40 mg) as documented by hospital or pharmacy records and with known LDL cholesterol ≥70 mg/dL within the prior 12 months.

Exclusion Criteria:

1. Age <21 years of age
2. Inability to give informed consent
3. Previous, current or planned treatment with a PCSK9 inhibitor
4. Known history of loss of function of PCSK9 (genetic mutation or sequence variation)
5. Patient with homozygous familial hypercholesterolemia (clinically or by previous genotyping)
6. Recent (<14 days) or active use of immunosuppressive drugs (including but not limited to high-dose corticosteroids [>1mg/kg of prednisone equivalent], Tumor Necrosis Factor-α blockers, cyclosporine) not including non-steroidal antinflammatory drugs or corticosteroids used for IV dye allergy or corticosteroids used as replacement therapy for pituitary/adrenal disease with a stable regimen for at least 6 weeks prior to randomization (note: topical, intra-articular, nasal, inhaled, and ophthalmic steroid therapies are not considered "systemic" and are allowed);
7. Chronic auto-immune or auto-inflammatory disease (including but not limited to rheumatoid arthritis, systemic lupus erythematosus);
8. 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;
9. Known chronic hepatitis B or C infection (excluding patients with a positive antibody who were successfully treated or who have demonstrated no viral load);
10. Known human immunodeficiency virus infection.
11. Use of fibrates other than fenofibrate within 6 weeks of the screening visit.
12. Uncontrolled hypothyroidism. Note: patients on thyroid replacement therapy can be included if the dosage of thyroxin has been stable for at least 12 weeks prior to screening.
13. Known history of a hemorrhagic stroke.
14. Has been previously treated with at least 1 dose of alirocumab or any other anti-PCSK9 monoclonal antibody in other clinical studies.

15. Conditions/situations such as:

    1. Any clinically significant abnormality identified at the time of screening that in the judgment of the investigator or any sub-investigator would preclude safe completion of the study or constrain assessment of endpoints, such as major systemic diseases or patients with short life expectancy.
    2. Patients considered by the investigator or any sub-investigator to be inappropriate for this study for any reason:

    i. Those patients deemed unable to meet specific protocol requirements, such as scheduled visits.

    ii. Those patients the investigator deems unable to administer or tolerate long-term injections.

    c. Investigator or any sub-investigator, pharmacist, study coordinator, other study staff, or relative thereof directly involved in the conduct of the protocol.

    d. Presence of any other conditions (geographic or social), actual or anticipated, that the investigator feels would restrict or limit the patient's participation for the duration of the study.

16. Thyroid-stimulating hormone (TSH) < lower limit of normal (LLN) or > upper limit of normal (ULN); if TSH is abnormal due to controlled hypothyroidism (patient is on a stable dose of thyroid replacement therapy), the patient may be enrolled into the study;
17. Exclusion Criteria Related to the Active Comparator and/or Mandatory Background Therapies: All contraindications to the background therapies or warnings/precautions of use (when appropriate) as displayed in the respective national product labeling.

18. Exclusion Criteria Related to the Current Knowledge of Alirocumab

    1. Known hypersensitivity to monoclonal antibody therapeutics
    2. Pregnant or breastfeeding women
19. Women of childbearing potential who are not protected by highly effective method(s) of birth control throughout the entire duration of study treatment and for 10 weeks after the last dose of study drug and/or who are unwilling or unable to be tested for pregnancy.
20. Men capable of impregnating women who are not protected by highly effective method(s) of birth control and/or who are unwilling to use an effective contraceptive method throughout the entire duration of study treatment and for 10 weeks after the last dose of study drug.
