Evaluate the Effect of Ethinyl Estradiol/Norgestimate on the Pharmacokinetics of Lomitapide in Healthy Female Subjects

The primary objective of this study is to assess the effect of ethinyl estradiol (EE)/norgestimate, a weak cytochrome P450 (CYP) 3A4 inhibitor, on the pharmacokinetics (PK) of lomitapide and 2 primary metabolites, M1 and M3.

This study will be a single center, randomized, open-label, 2 arm study to evaluate the effects of EE/norgestimate, a weak CYP3A4 inhibitor, on the PK of lomitapide in healthy female subjects when EE/norgestimate is administered simultaneously with lomitapide and when administration is separated by 12 hours.

Eligibility Criteria:

4. no known history of hypersensitivity or previous intolerance to lomitapide or EE/norgestimate
5. creatine phosphokinase, AST, and ALT levels must be below 1.5 times the upper limit of normal
6. clinical laboratory evaluations within the reference range for the test laboratory
7. negative test for selected drugs of abuse
8. negative hepatitis panel and negative HIV antibody screens

10. participation in any other investigational study drug trial within 30 days prior to Check-in;
11. use of any prescription medications/products within 14 days prior to Check-in unless deemed acceptable by the Investigator and Sponsor
12. use of any over-the-counter, nonprescription preparations within 7 days prior to Check-in, unless deemed acceptable by the Investigator and Sponsor

18. receipt of blood products within 2 months prior to Check-in;
19. any acute or chronic condition, scheduled hospitalization (inclusive of elective surgery during study) or scheduled travel prior to completion of all study procedures which, in the opinion of the Investigator, would limit the subject's ability to complete and/or participate in this clinical study;
20. subjects who, in the opinion of the Investigator, should not participate in this study.
