What this trial studies

This study evaluates a behavioral economics-informed intervention aimed at increasing persistence on pre-exposure prophylaxis (PrEP) among men who have sex with men (MSM) in South Africa. Participants will be randomized to receive either standard care or an intervention package that includes reminders, commitment pledges, and planning prompts to enhance their adherence to PrEP. The study aims to assess the feasibility and acceptability of this approach in a routine healthcare setting, with the ultimate goal of informing a larger effectiveness trial.

Why it matters

Potential benefit: If successful, this intervention could significantly improve adherence to PrEP, thereby reducing the incidence of HIV infections among MSM.

How similar studies have gone: Other studies have shown promise in using behavioral economics strategies to improve medication adherence, suggesting that this approach may be effective.
