Study Details

The primary objective of the study is to assess the pharmacodynamic (PD) effect of alirocumab on serum low density lipoprotein cholesterol (LDL-C) during 14 weeks of subcutaneous (SC) administered alirocumab in patients with autosomal dominant hypercholesterolemia (ADH) and gain-of-function mutation (GOFm) in 1 or both alleles of the proprotein convertase subtilisin/kexin type 9 (PCSK9) gene or with loss-of-function mutation (LOFm) in 1 or more alleles of the apolipoprotein (ApoB) gene.

Arms

  • Experimental: GOFm PCSK9 (Cohort 1): Alirocumab From Day 1
    Participants with gain-of-function mutation (GOFm) in proprotein convertase subtilisin/kexin type 9 (PCSK9) gene (Cohort 1): Alirocumab 150 mg subcutaneous (SC) injection at Week 0 (Day 1), Week 2 (Day 15), Week 4, 6 and 10 (matching placebo at Week 8, 12 and 14) during the double-blind period (Group A). Afterwards, participants have the possibility to continue in an open-label extension period with 150 mg alirocumab SC twice per week (Q2W) for an additional 3 years.
  • Experimental: GOFm PCSK9 (Cohort 1): Alirocumab From Day 15
    Participants with gain-of-function mutation (GOFm) in proprotein convertase subtilisin/kexin type 9 (PCSK9) gene (Cohort 1): Alirocumab 150 mg subcutaneous (SC) injection at Week 2 (Day 15), Week 4, 6, 8 and 12 (\[matching placebo at Week 0 (Day 1), 10 and 14\]) during the double-blind period (Group B). Afterwards, participants have the possibility to continue in an open-label extension period with 150 mg alirocumab SC twice per week (Q2W) for an additional 3 years.
  • Experimental: GOFm PCSK9 or LOFm ApoB (Cohort 2): Alirocumab from Day 1
    Participants with gain-of-function mutation (GOFm) in the proprotein convertase subtilisin/kexin type 9 (PCSK9) gene or loss-of-function mutation (LOFm) in the apolipoprotein (Apo) B gene (Cohort 2): Alirocumab 150 mg subcutaneous (SC) injection at Week 0 (Day 1), Week 2 (Day 15), Week 4, 6 and 10 (matching placebo at Week 8, 12 and 14) during the double-blind period (Group C). Afterwards, participants have the possibility to continue in an open-label extension period with 150 mg alirocumab SC twice per week (Q2W) for an additional 3 years.
  • Experimental: GOFm PCSK9 or LOFm ApoB (Cohort 2): Alirocumab from Day 15
    Participants with gain-of-function mutation (GOFm) in proprotein convertase subtilisin/kexin type 9 (PCSK9) gene or loss-of-function mutation (LOFm) in apolipoprotein (Apo) B gene (Cohort 2): Alirocumab 150 mg subcutaneous (SC) injection at Week 2 (Day 15), Week 4, 6, 8 and 12 (\[matching placebo at Week 0 (Day 1), 10 and 14\]) during the double-blind period (Group D). Afterwards, participants have the possibility to continue in an open-label extension period with 150 mg alirocumab SC twice per week (Q2W) for an additional 3 years.
