Long Term, Follow-on Study of Lomitapide in Patients With Homozygous Familial Hypercholesterolemia

A Phase III, Long Term, Open Label, Follow on Study of Microsomal Triglyceride Transfer Protein (MTP) Inhibitor 'Lomitapide' (LOMITAPIDE) in Patients With Homozygous Familial Hypercholesterolemia

This was a long term follow on study to assess the continued long term safety and efficacy of lomitapide in patients with homozygous familial hypercholesterolemia.

This was a phase III open label clinical trial to evaluate the long-term efficacy and safety of lomitapide at the maximum tolerated dose (for each patient) established during the clinical trial 733-005/UP1002. Subjects completing the 78-week treatment period in study 733-005/UP1002 who have not met any of the stopping criteria will be eligible to participate in 733-012. The treatment period continued until a decision was made by the local competent authority regarding marketing authorization. Lomitapide will be given orally once daily. Patient specific doses will be carried forward from 733-005/UP1002, but will not exceed the maximum tolerated dose the patient received during 733-005 /UP1002. The maximum dose for any patient was 80 mg/day. There was no reference therapy in this trial. The effects of the study drug were compared to baseline data (from 733-005/UP1002). Concomitant lipid-lowering therapy including plasmapheresis or LDL apheresis is permitted.

Note that hereafter, Week 0 in Study 733-005/UP1002 will be referred to as Baseline and Week 48 in Study AEGR-733-012 will be referred to as Week 126 (of overall treatment).
