Brief Summary:

This is a single arm, open label, multi centre phase III study to evaluate the efficacy and long term safety of lomitapide in paediatric patients with HoFH receiving stable LLT (including LA, when applicable) comprising of the following phases:

  • Screening Period (starting at Week 12, i.e. ≤12 weeks prior to Baseline for up to 6 weeks)
  • Stratified Enrolment and Start of Run in Period (starting at minimum at Week 6, i.e., 6 weeks prior to Baseline for a minimum of 6 weeks):
  • Efficacy Phase (starting at Baseline, i.e. Day [D] 0 for 24 weeks±3 days
  • Safety Phase (starting at Week 24±3 days for 80±1 weeks)

Condition or disease Intervention/treatment Phase
Homozygous Familial Hypercholesterolaemia (HoFH) Drug: Lomitapide Phase 3

Detailed Description:

Lomitapide has been approved for use in adult patients with HoFH in the European Union (EU) and European Economic Area (EEA), United States of America (USA), Israel, Argentina, Canada, Colombia, and Japan. This study is designed to determine if lomitapide is effective and can be safely administered to paediatric patients with HoFH. If the efficacy and safety so far observed in adults is confirmed in paediatric patients, the potential exists to significantly lower LDL C levels in paediatric patients with HoFH. Furthermore, the lower LDL C levels may reduce atherosclerosis progression and would be expected to benefit these paediatric patients with HoFH.

A single arm, non comparator design has been selected due to the rarity of the disease and because the evaluation of safety variables such as growth and sexual maturation requires longer term observation than would be feasible in the context of a placebo controlled study.

To mitigate the disadvantages of a single arm design, the study includes a Run in Period of at least 6 weeks during which current LLT (including LA, when applicable) will be stabilised to establish baseline levels allowing each patient to serve as his/her own control. Patients will also remain on stable LLT (including LA, when applicable) during the Efficacy Phase of the study through Week 24±3 days.

Primary Outcome Measures :
  1. Efficacy endpoint Percent change in LDL C [ Time Frame: Baseline through Week 104±1 week ]
    To evaluate the efficacy of lomitapide, as defined by the percent change in low density lipoprotein cholesterol (LDL C) at the maximum tolerated dose (MTD)

  2. Safety endpoints AE reporting [ Time Frame: Baseline through Week 104±1 week ]
    Incidence, severity, and relatedness of AEs


Secondary Outcome Measures :
  1. Percent change from Baseline at Week 24±3 days for the following lipid parameters: TC, Non HDL C, VLDL C, TG, Lp(a), and apoB [ Time Frame: Baseline through Week 104±1 week ]
  2. Percent change from Baseline at all other time points through Week 104±1 week for the following lipid parameters: LDL C, TC, Non HDL C, VLDL C, TG, Lp(a), and apo B [ Time Frame: Baseline through Week 104±1 week ]
  3. • Change in LLT and LA from Week 24±3 days through Week 104±1 week [ Time Frame: Baseline through Week 104±1 week ]
  4. • Total number and percent of patients achieving the EAS recommended target LDL C of <135 mg/dL (3.5 mmol/L) in paediatric HoFH patients at Week 24±3 days and at any time on study [ Time Frame: Baseline through Week 104±1 week ]
