Study Details
Study Description
Brief Summary
This is a Phase 3 single-arm, open-label, international, multi-center clinical trial to evaluate the efficacy and safety of lomitapide in pediatric patients with HoFH who are receiving stable lipid-lowering therapy, including LDL apheresis. The study is comprised of a 12-week Run-in Period, a primary 24-week Efficacy Phase, followed by an 80-week Safety Phase.
