Summary
Brief summary
Participants with documented homozygous familial hypercholesterolemia (HoFH) who have
provided informed consent will receive 2 open-label doses of ARO-ANG3 and be evaluated for
safety and efficacy parameters through 36 weeks. Participants who complete the first 36 week
treatment period may opt to continue in an additional 24-month extension period during which
they will receive up to 8 doses open-label doses of ARO-ANG3.
