To Evaluate the Effects of Odalasvir and AL-335 With Simeprevir on the Single-Dose Pharmacokinetics of Ethinylestradiol and Drospirenone in Healthy Female Participants

A Phase 1, Open-label Study in Healthy Female Subjects to Investigate the Effects of Odalasvir and AL-335 at Steady-state, Given as Single Agents and in Combination With Simeprevir, on the Single-dose Pharmacokinetics of Ethinylestradiol and Drospirenone

The purpose of this study is to evaluate the effect of steady-state concentrations of odalasvir (ODV), AL-335 and the combination of the 3-direct-acting anti-viral agents (3-DAA) ODV, AL-335, and simeprevir (SMV) on the single-dose pharmacokinetic (PK) of drospirenone and ethinylestradiol in healthy female participants.

Inclusion Criteria:

• Participant must be a female of childbearing potential with a normal menstrual cycle
• Participant must have a body mass index (BMI; weight in kg divided by the square of height in meters) between 18.0 and 30.0 kilogram per square meter (kg/m^2), extremes included, and a body weight not less than 50.0 kilogram (kg)
• Participant must have a blood pressure (after the participant is supine for 5 minutes) between 90 and 140 millimeter of mercury (mmHg) systolic, inclusive, and no higher than 90 mmHg diastolic. If blood pressure is out of range, up to 2 repeated assessments are permitted
• Participant must have a negative serum (beta human chorionic gonadotropin [beta- hCG]) pregnancy test at screening
• Participant must have a negative highly sensitive urine pregnancy test at Day -1

Exclusion Criteria:

• Participant is peri- or postmenopausal, or participant with bilateral oophorectomia
• Participant has a history of hepatitis B surface antigen (HBsAg) or hepatitis C antibody (anti-HCV) positive, or other clinically active liver disease, or tests positive for HBsAg or anti-HCV at screening
• Participant has previously been dosed with simeprevir (SMV), odalasvir (ODV), or AL-335 in more than 3 single dose studies, or a multiple-dose study with SMV, ODV, or AL-335
• Participant with currently active gynecological disorders including, but not limited to, vaginal bleeding without an obvious reason and hyperprolactinemia with or without galactorrhea
• Participant with a past history of: heart arrhythmias (example, extrasystolic rhythms or tachycardia at rest). Isolated extrasystolic beats are not exclusionary; risk factors associated with Torsade de Pointes such as hypokalemia; family history of short/long QT syndrome; sudden unexplained death (including sudden infant death syndrome [SIDS]) in a first-degree relative (that is, sibling, offspring, or biological parent)
