Acceptability and Feasibility of Injectable Cabotegravir Pre-exposure Prophylaxis (PrEP) Versus Oral PrEP in Routine Care up to 15 Months in Private Pharmacies in South Africa

This is a mixed methods study employing a convergence model triangulation design. Participants in the study will be sexually active young adults starting Pre-exposure Prophylaxis at private pharmacies, who will be offered either Cabotegravir Long-Acting Injectable, oral Pre-exposure Prophylaxis (TDF/FTC\[3TC\]), or Pre-exposure Prophylaxis deferment at each of their regular visits, with the option to switch between options for up to 15 months, with a final exit interview following the transition to standard-of-care. The number of study visits will vary, depending on participant Pre-exposure Prophylaxis choices. Those choosing oral Pre-exposure Prophylaxis will be seen 3 monthly from V2 onwards, but those choosing Cabotegravir Long-Acting Injectable will be seen 2 monthly from V2. A maximum of 9 visits is possible.
