Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Primary Objective:

To evaluate the efficacy of alirocumab administered every 2 weeks (Q2W) and every 4 weeks (Q4W) versus placebo after 24 weeks of double-blind (DB) treatment on low-density lipoprotein cholesterol (LDL-C) levels in participants with heterozygous familial hypercholesterolemia (heFH) 8 to 17 years of age on optimal stable daily dose of statin therapy ± other lipid modifying therapies (LMTs) or a stable dose of non-statin LMTs in case of intolerance to statins.

Secondary Objectives:

* To evaluate the efficacy of alirocumab versus placebo on LDL-C levels.
* To evaluate the effects of alirocumab versus placebo on other lipid parameters.
* To evaluate the safety and tolerability of alirocumab in comparison with placebo.
* To evaluate the efficacy, safety, and tolerability of alirocumab after open label treatment.
* To evaluate the development of anti-alirocumab antibodies.

Placebo/Alirocumab Q2W

Participants received subcutaneous (SC) injection of placebo (matched to alirocumab) based on their body weight (BW) (less than \[\<\] 50 kilograms \[kg\] or greater than or equal to \[\>=\] 50 kg) Q2W for 24 weeks in DB treatment period added to stable LMT. After completion of DB treatment period, eligible participants entered into OL treatment period and received alirocumab 40 milligrams (mg) (for BW \<50 kg) or 75 mg (for BW \>=50 kg) Q2W from Week 24 up to an additional 80 weeks (i.e., up to Week 104) added to stable LMT. After Week 24, dose up-titrated from 40 mg to 75 mg when BW increased from \<50 kg to \>=50 kg. From Week 32 up to Week 104, based on participant LDL-C value, alirocumab dose was either up-titrated as 40 mg to 75 mg (for BW \<50 kg) or 75 mg to 150 mg (for BW \>=50 kg) or down titrated as 75 mg to 40 mg (for BW \<50 kg) or 150 mg to 75 mg (for BW \>=50 kg).

Participants received SC injection of alirocumab 40 mg (for BW \<50 kg) or 75 mg (for BW \>=50 kg) Q2W for 24 weeks in DB treatment period added to stable LMT. Alirocumab dose was up-titrated to 75 mg or 150 mg Q2W from Week 12, when LDL-C level was \>=110 milligrams per deciliter (mg/dL) (2.85 millimoles per liter \[mmol/L\]) at Week 8. After completion of DB treatment period, eligible participants entered into OL treatment period and received alirocumab 40 mg (for BW \<50 kg) or 75 mg (for BW \>=50 kg) from Week 24 up to an additional 80 weeks (i.e., up to Week 104) added to stable LMT. After Week 24, dose up-titrated from 40 mg to 75 mg when BW increased from \<50 kg to \>=50 kg. From Week 32 up to Week 104, based on participant LDL-C value, alirocumab dose was either up-titrated as 40 mg to 75 mg (for BW \<50 kg) or 75 mg to 150 mg (for BW \>=50 kg) or down titrated as 75 mg to 40 mg (for BW \<50 kg) or 150 mg to 75 mg (for BW \>=50 kg).
