Experience with Lojuxta® in Italy Review of the recent experience of Lojuxta® in Italy with Lojuxta® used as an adjunct to apheresis

Claudia Morozzi Department of Molecular Medicine,

Sapienza University Rome, Italy

2

Traditional lipid-lowering therapies (statins and ezetimibe) are largely ineffective in HoFH patients, and extracorporeal lipoprotein apheresis (LA) forms the mainstay of treatment. Lomitapide is a microsomal triglyceride transfer protein inhibitor approved for the treatment of HoFH as an adjunct to LA. We undertook to examine the efficacy and safety of lomitapide in seven HoFH patients treated with LA in the Lipid Clinic and Therapeutic Apheresis Unit in Rome, Italy outside of a clinical trial setting.

Background

3

Methods Seven patients with genetically determined HoFH were treated with lomitapide in the normal course of their therapy. All patients received LA either weekly or biweekly. Lomitapide was administered according to the approved EU prescribing information. LDLC levels, liver enzymes and hepatic fat were monitored. Length of follow-up varied between 12 and 50 weeks.

Treatment history

Results After titration, lomitapide doses ranged from 10–30 mg/day for most (5/7) patients. One patient received lomitapide 50 mg/day and another 5 mg/day. Three patients achieved LDLC reductions of >50%. The patient on the lowest lomitapide dose did not gain significant benefit. Gastrointestinal adverse events were managed via alterations to dietary fat intake.

Conclusion Lomitapide is an effective adjunct to LA in patients with HoFH. Adverse events are manageable; GI adverse events can be managed with a low-fat eating plan.
