Participant Flow

The study was conducted at five sites in United States, Canada, and the Netherlands between 04 Feb 2015 and 23 Jul 2018. A total of 12 participants were screened in the study. Out of 12 participants, 9 participants received the study treatment.

This study consisted of 2 screening periods: 1st for main study and 2nd for open label extension (OLE) period. Participants on stable background medical lipid-modifying therapy for at least 4 weeks prior to screening, or who didn't undergo lipid apheresis within 4 weeks prior to screening visit, were directly entered into a 2-week screening period.

Measure
REGN1500 250 mg SC/15 mg/kg IV/450 mg SC
n=9 Participants
Participants received single dose of REGN1500 subcutaneous (SC) injection of 250 milligrams (mg) at Week 0 (Day 1), followed by single dose of REGN1500 intravenous (IV) injection of 15 milligrams per kilogram (mg/kg) at Week 2 (Day 15) and then followed by 4 doses of REGN1500 SC injection of 450 mg once weekly starting from Week 12 (Day 85). Only the first 2 enrolled participants received 4 weekly REGN1500 450 mg SC doses at weeks 12, 13, 14, and 15 per the protocol. This dose regimen was removed under protocol amendment 4. Participants were followed for a period of 24 weeks (through Week 26 \[Day 183\]) after the last dose of study drug in the main study period.

REGN1500 250 mg SC/15 mg/kg IV/450 mg SC
n=8 Participants
Participants received single dose of REGN1500 subcutaneous (SC) injection of 250 milligrams (mg) at Week 0 (Day 1), followed by single dose of REGN1500 intravenous (IV) injection of 15 milligrams per kilogram (mg/kg) at Week 2 (Day 15) and then followed by 4 doses of REGN1500 SC injection of 450 mg once weekly starting from Week 12 (Day 85). Only the first 2 enrolled participants received 4 weekly REGN1500 450 mg SC doses at weeks 12, 13, 14, and 15 per the protocol. This dose regimen was removed under protocol amendment 4. Participants were followed for a period of 24 weeks (through Week 26 \[Day 183\]) after the last dose of study drug in the main study period.
