Arm Intervention/treatment
Active Comparator: Standard of Care
Participants received standard of care (SOC) treatment for the first year of the study (SOC-controlled period). At week 48, participants began treatment with evolocumab at a dose of either 140 mg every 2 weeks (Q2W) or 420 mg every month (QM), based on participant choice, for approximately 2 years during the all-investigational product [all-IP] period.
 Biological: Evolocumab
Administered by subcutaneous injection either every 2 weeks or once a month (patient preference) using a prefilled autoinjector pen
Other Names:
  • AMG 145
  • Repatha

Drug: Standard of Care
Standard of care therapy as per local practices. This could include prescribed therapies and/or dietary/exercise regimes
Experimental: Evolocumab + Standard of Care
Participants received subcutaneous evolocumab plus standard of care during the first year of the study (SOC-controlled period) and for approximately 2 years during the all-IP period. Evolocumab was administered at a dose of 140 mg every 2 weeks (Q2W) or 420 mg every month (QM) based on participant choice.
 Biological: Evolocumab

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of Participants With Adverse Events [ Time Frame: 48 weeks in the SOC-controlled period and up to 2 years in the All-IP period ]
    Adverse event (AE) severity assessments were made using National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) grading, version 4.0, where grade 1 = mild AE, grade 2 = moderate AE, Grade 3 = severe AE, grade 4 = life-threatening AE and Grade 5 = death due to AE.


Secondary Outcome Measures :
  1. Percent Change From Baseline in LDL-C at Weeks 48 and 104 [ Time Frame: Baseline of the parent study and weeks 48 amd 104 ]
  2. Change From Baseline in LDL-C at Weeks 48 and 104 [ Time Frame: Baseline of the parent study and weeks 48 amd 104 ]
