简要总结
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.
