This study is researching an experimental drug called alirocumab, referred to as "study drug". In the United States, alirocumab is approved for the treatment of hypercholesterolemia (high blood cholesterol levels).

The aim of the study is to see how safe and effective alirocumab is when given weekly to adult participants who have hypercholesterolemia.

The study is looking at several other research questions, including:

• What side effects may happen from taking the study drug once a week
• How much study drug is in the blood at different times

Key Inclusion Criteria:

1. Participant has elevated LDL-C level, as defined in the protocol

Key Exclusion Criteria:

1. Participant plans to initiate or change dose of lipid-lowering therapy
2. Use of any PCSK9 inhibitors

NOTE: Other Protocol-Defined Inclusion/Exclusion Criteria Apply

All Individual Patient Data (IPD) that underlie publicly available results will be considered for sharing.

When Regeneron has:

• received marketing authorization from major health authorities (e.g., FDA, European Medicines Agency (EMA), Pharmaceuticals and Medical Devices Agency (PMDA), etc.) for the product and indication or has globally discontinued development of the product for all indications on or after April 2020 and has no plans for future development
• made the study results publicly available (e.g., scientific publication, scientific conference, clinical trial registry)
• the legal authority to share the data, and
• ensured the ability to protect participant privacy

Qualified researchers can submit a proposal for access to individual patient or aggregate level data from a Regeneron-sponsored clinical trial through Vivli.
