Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
To evaluate the effect of alirocumab on low-density lipoprotein cholesterol (LDL-C) levels after 8 weeks of treatment in heterozygous familial hypercholesterolemia (heFH) participants aged of 8 to 17 years, with LDL-C \>=130 milligrams per deciliter (mg/dL) (3.37 millimoles per litre \[mmol/L\]) 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 for at least 4 weeks prior to the screening period.
Secondary Objective:
* To evaluate the safety and tolerability of alirocumab.
* To evaluate the pharmacokinetics profile of alirocumab.
* To evaluate the effects of alirocumab on other lipid parameters.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
For Cohort 4, a study duration of approximately 14-19 weeks (screening period up to 6 \[+1\] weeks, open-label dose finding treatment period: 12 weeks).
Optional extension period: up to a maximum of 2 years for the first participants enrolled in Cohorts 1 to 3, but a maximum of approximately 5 months for the first participants enrolled in Cohort 4.
For all participants who declined participation in the phase 3 study, their last alirocumab injection was on December 2018.

Cohort 1 - Alirocumab 30 mg Q2W: <50 kg
Period 1: Participants with body weight less than (\<) 50 kilograms (kg) received subcutaneous (SC) injection of alirocumab 30 milligram(mg) administered every 2 weeks (Q2W) up to 8 weeks added to lipid modifying therapy (LMT).
Period 2: Participants with body weight \< 50 kg received SC injection of alirocumab 30 mg administered Q2W from Week 16 until they started receiving dose matching to Cohort 2 dosage including dose adjustment to body weight as required. Cohort 2 dosage was: if body weight was still \< 50 kg, participants received SC injection of alirocumab 40 mg administered Q2W until Week 130; if body weight was \> = 50 kg participants received SC injection of alirocumab 75 mg administered Q2W until Week 130.
