Description of intervention(s) / exposure
Treatment: Drugs - SOF/VEL/VOX
Treatment: Drugs - VOX
Treatment: Drugs - Norgestimate/ethinyl estradiol

Experimental: SOF/VEL/VOX + VOX - Part A: Participants without a documented history of taking norgestimate/ethinyl estradiol for at least one menstrual cycle will receive norgestimate/ethinyl estradiol. Participants with a documented history of taking norgestimate/ethinyl estradiol may enroll directly into Part B of the study.

Part B: Participants will continue taking norgestimate/ethinyl estradiol for the remainder of the study and will receive SOF/VEL/VOX FDC plus VOX.

400/100/100 mg FDC tablet administered orally once daily

Treatment: Drugs: VOX
100 mg tablet administered orally once daily

Treatment: Drugs: Norgestimate/ethinyl estradiol
Norgestimate 0.180 mg/0.215 mg/0.25 mg/ethinyl estradiol 0.025 mg tablet administered orally once daily according to the package insert

Summary
Brief summary
This study will evaluate the effect of sofosbuvir (SOF)/velpatasvir (VEL)/voxilaprevir (VOX) fixed-dose combination (FDC) + voxilaprevir on the pharmacokinetics (PK) of a representative hormonal contraceptive medication, norgestimate/ethinyl estradiol (Ortho Tri-Cyclen® Lo (OC)) and will assess the effect of norgestimate/ethinyl estradiol on the PK of SOF/VEL/VOX+VOX.
