Safety, PK/PD, acceptability, and desirability or a novel HIV prevention douche among adolescent men (DREAM)

 

DREAM logoThe purpose of the overall study is to ensure the inclusion of adolescent and young adults’ perspectives as next generation biomedical prevention, specifically a rectal douche (TFV microbicide; 660mg TFV in 125mL half-normal saline), during its clinical testing and development for safety and efficacy.  

We recruited young men who have sex with men (YMSM) who have expressed interest in being contacted to screen for eligibility into a Phase I HIV prevention biomedical trial. We expected to initially screen 48 YMSM living in the greater Baltimore Metropolitan Area to enroll 16 evaluable participants. YMSM who are willing and cleared to participate in the Trial visit were reconsented and asked to use a single dose of the TFV douche at the Hopkins study site. Prior to using the douche, baseline samples (see Appendix 1) were collected to establish pre-dose conditions for safety assessments as well as sample collection for TFV analyte concentration in multiple matrices for participants taking oral TDF/FTC PrEP. These concentrations were used to adjust post-dose PK and PD assessments. Participants also completed a post-dose survey and an in-depth interview (IDI) regarding product acceptability and experiences participating in the study at their termination visit. 

As a second aim of this protocol, we also conducted in-depth interviews with individuals who choose not to participate in the Phase I Safety Trial or who were not eligible after medical screening (N=32) in order to examine perceived barriers and facilitators to their willingness to participate in biomedical trials, and examine their suggestions to maximize YMSM’s engagement in future biomedical trials.

Accrual is expected to be complete within approximately 9 months. Each participant will be on study for approximately 2-3 months. The total duration of the study will be approximately 1 year.

We are recruiting 48 YMSM who gave permission to be contacted and expressed initial interest in an in-person Screening Visit. These 48 YMSM come from a larger online survey (n=500) focused on YMSM’s willingness to participate in biomedical trials. We will then aim to screen and consent approximately 48 YMSM in-person to enroll 16 YMSM for the Phase I Safety Trial.
