Study Summary

This is a research study to determine the best way to dose Truvada®, an oral medication licensed to be taken as Pre-Exposure Prophylaxis (PrEP) to prevent HIV infection, in transgender women who are also taking feminizing hormones. The duration of the study is about 4 months, and involves a screening visit, a baseline visit with colon biopsies and kidney function testing, and several outpatient visits, including 5 intensive sampling visits that last about 9 hours and involve colon biopsies, kidney function testing and other blood specimen collections. After the baseline visit, participants will start on PrEP, daily Truvada® pills, and will continue on the Truvada® for 5 weeks. Participants will then receive either an injection of Lupron, oral low-dose estradiol or oral high-dose estradiol, which will be taken along with the Truvada® PrEP for 1-2 weeks before returning for an intensive sampling visit.

Primary Outcome

Plasma TFV Cmax was defined as the highest observed concentration during the 24 hour (h) dosing interval and determined via non-compartmental analyses. Median maximum concentrations with interquartile ranges (IQR) were determined. Differences in TFV Cmax concentrations were determined for each participant, and each dosing period was compared to the PrEP Only Dosing Period. The median intra-individual difference in TFV Cmax, with IQRs, was calculated.
