Drug Information available for: Evolocumab

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 52 participants began treatment with evolocumab 420 mg once a month (QM) for 4 years during the all-investigational product [all-IP] period.
Biological: Evolocumab
Administered by subcutaneous injection
Other Names:
  • AMG 145
  • Repatha

Other: Standard of care
Standard of care therapy as per local practices. This could include prescribed therapies and/or dietary/exercise regimes

Experimental: Evolocumab + SOC
Participants received evolocumab 420 mg once a month plus standard of care for the first year of the study (SOC-controlled period). At week 52 participants continued treatment with evolocumab 420 mg QM for another 4 years during the all-IP period.
Biological: Evolocumab
Administered by subcutaneous injection
Other Names:
  • AMG 145
  • Repatha




Primary Outcome Measures :
  1. Number of Participants With Adverse Events [ Time Frame: 52 weeks in the SOC-controlled period and up to 4 years in the All-IP period; actual median duration of treatment in the All-IP period was 46.9 months. ]
    Adverse event (AE) severity assessments were made using National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) grading, version 4.03, 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. Low-density Lipoprotein Cholesterol (LDL-C) Level at Week 24 and Week 52 [ Time Frame: Baseline of parent study and extension study weeks 24 and 52 ]
  2. Non-high-density Lipoprotein Cholesterol (Non-HDL-C) Level at Week 24 and Week 52 [ Time Frame: Baseline of parent study and extension study weeks 24 and 52 ]
  3. Apolipoprotein B Level at Week 24 and Week 52 [ Time Frame: Baseline of parent study and extension study weeks 24 and 52 ]
  4. Total Cholesterol/HDL-C Ratio at Week 24 and Week 52 [ Time Frame: Baseline of parent study and extension study weeks 24 and 52 ]
  5. Apolipoprotein B/Apolipoprotein A1 Ratio at Week 24 and Week 52 [ Time Frame: Baseline of parent study and extension study weeks 24 and 52 ]
