Acceptability of Event-Driven and Long-Acting HIV Pre-Exposure Prophylaxis Formulations Among Transgender Women Engaged in Street-Based Sex Work in Baltimore, Maryland.

We assessed acceptability of nonoral HIV pre-exposure prophylaxis (PrEP) formulations among transgender women (TW) engaged in street-based sex work in Baltimore, Maryland. In a K -means cluster analysis, TW ( N =36) were partitioned into groups characterized by high interest in long-acting injectable PrEP only ( Injectable Enthusiasts , 36%), high interest in injectables and subdermal implants ( Long-Acting Acceptors , 36%), and low interest across PrEP formulations ( Non-Acceptors , 28%). TW's interest in novel PrEP agents varied widely across formulations (range: 22-66%) and clustered around numerous relational, occupational, and structural factors, highlighting the importance of availing multiple PrEP formulations for this impacted population.
