Study Arms:
- Cohort 1 - Alirocumab 30 mg Q2W: <50 kg (Type: EXPERIMENTAL): 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.
- Cohort 1 - Alirocumab 50 mg Q2W: >=50 kg (Type: EXPERIMENTAL): Period 1: Participants with body weight greater than or equal to (\>=) 50 kg received SC injection of alirocumab 50 mg administered Q2W up to 8 weeks added to LMT.~Period 2: Participants with body weight \>= 50 kg received SC injection of alirocumab 50 mg administered Q2W from Week 16 until switch to Cohort 2 dosage then SC injection of alirocumab 75 mg administered Q2W until Week 130.
- Cohort 2 - Alirocumab 40 mg Q2W: <50 kg (Type: EXPERIMENTAL): Period 1: Participants with body weight \< 50 kg received SC injection of alirocumab 40 mg administered Q2W up to 8 weeks added to LMT.~Period 2: Participants with body weight \< 50 kg received SC injection of alirocumab 40 mg administered Q2W from Week 16 until switch of dosage in Cohorts 1 and 3. If body weight was still \< 50 kg, participants continued to receive 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.
- Cohort 2 - Alirocumab 75 mg Q2W: >=50 kg (Type: EXPERIMENTAL): Period 1: Participants with body weight \>= 50 kg received SC injection of alirocumab 75 mg administered Q2W up to 8 weeks added to LMT.~Period 2: Participants with body weight \>= 50 kg received SC injection of alirocumab 75 mg administered Q2W from Week 16 until Week 130.
- Cohort 3 - Alirocumab 75 mg Q4W: <50 kg (Type: EXPERIMENTAL): Period 1: Participants with body weight \< 50 kg received SC injection of alirocumab 75 mg administered every 4 weeks (Q4W) up to 8 weeks added to LMT.~Period 2: Participants with body weight \< 50 kg received SC injection of alirocumab 75 mg administered Q4W from Week 14 until switch to Cohort 2 dosage including dose adjustment to body weight as required, then Cohort 2 dosage: 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.
- Cohort 3 - Alirocumab 150 mg Q4W: >=50 kg (Type: EXPERIMENTAL): Period 1: Participants with body weight \>= 50 kg received SC injection of alirocumab 150 mg administered Q4W up to Week 8 added to LMT.~Period 2: Participants with body weight \>= 50 kg received SC injection of alirocumab 150 mg administered Q4W from Week 14 until switch to Cohort 2 dosage then SC injection of alirocumab 75 mg administered Q2W until Week 130.
- Cohort 4 - Alirocumab 150 mg Q4W: <50 kg (Type: EXPERIMENTAL): Period 1: Participants with body weight \< 50 kg received SC injection of alirocumab 150 mg administered Q4W up to 12 weeks added to LMT.~Period 2: Participants with body weight \< 50 kg received SC injection of Alirocumab 150 mg administered Q4W from Week 12 until Week 48.
- Cohort 4 - Alirocumab 300 mg Q4W: >=50 kg (Type: EXPERIMENTAL): Period 1: Participants with body weight \>= 50 kg received SC injection of alirocumab 300 mg administered Q4W up to 12 weeks added to LMT.~Period 2: Participants with body weight \>= 50 kg received SC injection of alirocumab 300 mg administered Q4W from Week 12 until Week 48.
