Primary Outcome(s)

Secondary Objective: -To evaluate the efficacy of alirocumab after treatment on LDL-C levels.
-To evaluate the effects of alirocumab on other lipid parameters.

5. Percent change in total cholesterol (total-C) (pre-apheresis, if applicable).
6. Percent change in lipoprotein (a) (Lp(a)) (pre-apheresis, if applicable).
7. Percent change in high-density lipoprotein cholesterol (HDL-C) (pre-apheresis, if applicable).
