Subjects with HeFH:
-Completed Study 20120123 while still on assigned investigational product.
Subjects with HoFH:
-Male or female, = 10 to = 17 years of age at time of enrollment
-Diagnosis of HoFH by genetic confirmation or a clinical diagnosis based on a
history of an untreated LDL cholesterol concentration > 500 mg/dL (13 mmol/L)
together with either xanthoma before 10 years of age or evidence of
heterozygous familial hypercholesterolemia in both parents.
All subjects:
- Subject must be on a low-fat diet and receiving background lipid-lowering therapy
-Lipid-lowering therapy, including statin dose, must be unchanged for = 4 weeks
prior to LDL-C screening; fibrates must be stable for at least 6 weeks prior to
screening.
Are the trial subjects under 18? yes
Number of subjects for this age range: 115
F.1.2 Adults (18-64 years) no
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) no
F.1.3.1 Number of subjects for this age range
Subjects with HoFH:
- estimated glomerular filtration rate (eGFR) < 30 ml/min/1.73m2; CK > 3x ULN; AST or ALT > 3x ULN; (all screening by central laboratory);
- known active infection or major hematologic, renal, metabolic, gastrointestinal or endocrine dysfunction;
- subject has taken a cholesterylester transfer protein (CETP) inhibitor in the last 12 months, or mipomersen or lomitapide in the last 5 months prior to LDL-C screening, or has received any therapy to inhibit proprotein convertase subtilisin/kexin type 9 (PCSK9) within 12 weeks prior to screening;
- subject has a history or evidence of any other clinically significant disorder, condition or disease, or planned or expected procedure that, in the opinion of the Investigator or Amgen physician, would pose a risk to subject safety or interfere with the study evaluation, procedures or completion.
The following are major exclusion criteria for all subjects:
- subjects cannot be receiving treatment in another investigational device or drug study, or less than 30 days since ending treatment on another investigational device or drug study;
- female subjects of childbearing potential cannot be pregnant or breast feeding or planning to become pregnant or planning to breast feed and must be willing to use acceptable method(s) of effective birth control (may include true sexual abstinence) during treatment with evolocumab and for an additional 15 weeks after the end of treatment with evolocumab.

Name Time Method Main Objective: To describe the safety and tolerability of 80 weeks of SC evolocumab when added to standard of care in pediatric subjects 10 to 17 years of age with HeFH or HoFH.;Secondary Objective: To describe percent change and change from baseline in LDL-C, and on percent change from baseline in non-high-density lipoprotein cholesterol (non-HDL-C), apolipoprotein B (ApoB), total cholesterol/HDL-C ratio, and ApoB/Apolipoprotein A-1 (ApoA1) ratio.;Primary end point(s): Subject incidence of treatment emergent adverse events;Timepoint(s) of evaluation of this end point: Screening, day 1, weeks 4, 12, 24, 36, 48, 60, 72 and 80.
