PRIMARY outcome

Timeframe: Pre dose and 1, 2, 3, 4, 5, 6, 8, 10, 12, 18, 24, 48, 72, 96, 120, 144, and 168 hours post dose.

Population: Only 13 subjects who had evaluable PK data in both study periods were included in the PK analysis of lomitapide. One subject was excluded from PK analysis of M1 and M3 during Period 1 due to early termination. Another subject was excluded from PK analysis of M1 and M3 during Period 2 because the subject did not complete both Periods 1 and 2.

Measure
Period 1
n=15 participants at risk
All 15 subjects who were enrolled in the study received at least one 20 mg dose of lomitapide and had assessments for the analysis of safety during Period 1.
Period 2
n=13 participants at risk
Only 13 subjects who were enrolled in the study received 2 single daily doses of 20 mg lomitapide as planned (one dose in each of the two study periods). 2 subjects who only received one dose in Period 1 due to early withdrawal were not included in analysis of safety during Period 2.
