Long-acting Injectable Cabotegravir for PrEP

The purpose of this study is to understand PrEP user choices, preferences and implementation impact of the roll-out of long-acting injectable PrEP alongside oral PrEP among women in Blantyre, Malawi.

This study is being done to understand how long-acting injectable cabotegravir (CAB-LA) used for HIV pre-exposure prophylaxis (PrEP) and hormonal contraceptive methods affect each other when used at the same time. Women who are already using CAB-LA or not using PrEP will choose to join one of several groups based on whether they use injectable contraceptive (IM DMPA), an etonogestrel implant, or no hormonal contraceptive. Participants will have study visits every 4 to 12 weeks for up to 12 or 24 weeks after starting a contraceptive method to collect blood samples and measure levels of CAB-LA and hormone concentrations. The study will compare these levels to see if taking CAB-LA changes hormone concentrations or if using hormonal contraception changes CAB-LA drug levels. Safety, side effects, satisfaction, and continuation of CAB-LA PrEP and contraceptive methods will also be evaluated.

The purpose of this study is to identify the effectiveness of a bundle of strategies to support continuation of clients on pre-exposure prophylaxis, including long-acting injectable cabotegravir and oral pre-exposure prophylaxis to high priority groups.
