The primary hypothesis is that a dose of evolocumab (AMG 145) every-4-weeks (Q4W) subcutaneous (SC) will be well tolerated and will result in greater lowering of Low-Density Lipoprotein Cholesterol (LDL-C) at week 12 than placebo in subjects with heterozygous familial hypercholesterolemia

Primary Outcome Measures:
  • The percent change from baseline in Low-Density Lipoprotein Cholesterol (LDL-C) at week 12 [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Absolute change from baseline in Low-Density Lipoprotein Cholesterol (LDL-C) at week 12 [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Percent change from baseline in non-High Density Lipoprotein Cholesterol (HDL-C) at week 12 [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Percent change from baseline in Apolipoprotein B (ApoB) at week 12 [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Percent change from baseline in the total cholesterol/High Density Lipoprotein Cholesterol (HDL-C) at week 12 [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Percent change from baseline in Apolipoprotein B (ApoB)/Apolipoprotein A-1 (ApoA1) ratio at week 12 [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
