Summary

This trial will study PrEP levels in trans/non-binary folks taking gender-affirming hormones. They'll get personalized text reminders and take F/TAF for 48 weeks. 60 people will be enrolled.

Who is the study for?
This trial is for transgender or non-binary adults over 18 who are HIV-negative, currently taking F/TDF for PrEP, and have good kidney function. They must be willing to switch to F/TAF for PrEP. People with active hepatitis B, gastrointestinal issues affecting drug absorption, severe bone density conditions, major psychiatric disorders, certain kidney diseases, suspected drug allergies or those on conflicting medications cannot participate.
What is being tested?
The study tests the effectiveness of a daily oral dose of Emtricitabine Tenofovir Alafenamide (F/TAF) as an alternative to Emtricitabine / Tenofovir Disoproxil (F/TDF) in preventing HIV. It also examines how gender-affirming hormone therapy affects PrEP levels. Participants will receive adherence support via personalized text messages for 48 weeks.
What are the potential side effects?
Potential side effects may include digestive issues like nausea or diarrhea; headaches; fatigue; and changes in liver enzymes which could affect organ function. There might also be rare risks related to bone health or kidney function.
