Primary outcomePrimary: Cmax for Arm 1 (Lomitapide & EE/Noregestimate - Taken Together) — 1.03; 1.39; 2.96; 2.95 ng/mL
Summary
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.
