Evaluate the Effect of Atorvastatin on the Pharmacokinetics of Lomitapide in Healthy Subjects.

Phase 1

Completed

Conditions: Effect of Atorvastatin on the Pharmacokinetics of Lomitapide

Interventions: Drug: lomitapide
Drug: Atorvastatin

Registration Number: NCT02080455

Lead Sponsor: Aegerion Pharmaceuticals, Inc.

Brief Summary: The primary objective of this study is to assess the effect of atorvastatin, a weak cytochrome P450 (CYP) 3A4 inhibitor, on the pharmacokinetics (PK) of lomitapide and its 2 primary metabolites, M1 and M3.

Detailed Description: This study will be a single center, randomized, open-label, 2-arm study to evaluate the effects of atorvastatin, a weak CYP3A4 inhibitor, on the PK of lomitapide in healthy male and female subjects when atorvastatin is administered simultaneously with lomitapide and when it is administered 12 hours after lomitapide.
