Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To evaluate adherence to a single dual-prevention pill (DPP) compared with a two-pill regimen (2PR) for pre-exposure prophylaxis (PrEP) and pregnancy prevention in women without HIV.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To evaluate adherence to a single DPP consisting of co-formulated Tenofovir Disoproxil Fumarate and Emtricitabine (FTC/TDF) plus combined ethinyl estradiol/levonorgestrel oral contraceptive (COC), compared with a two-pill regimen (2PR) consisting of daily oral FTC/TDF pill and combined COC pill, for pre-exposure prophylaxis PrEP and pregnancy prevention in women without HIV.
