Summary
This is a Phase 2, multi-site, two-period, open label randomized crossover (Period 1 and 2) study. Participants are randomized 1:1 to one of two 8-week on-demand product sequences - TFV douche then oral F/TDF or oral F/TDF then TFV douche - with a 2 to 4-week washout period in between. Domains of safety, acceptability, adherence, and PK/PD (sub-study only) are assessed for each product.
Who is the study for?
This trial is for individuals willing to compare two forms of a drug called Tenofovir: one taken by mouth and the other used as a rectal douche. Participants will try both methods in different sequences with a break in between. The study aims to assess safety, how well people like the method, if they stick with it, and how the body processes the drug.
What is being tested?
The study is testing oral F/TDF pills against TFV rectal douches in an on-demand fashion over two periods. Each participant will use both formulations for 8 weeks each, separated by a short break. Researchers want to see which form is safer, more acceptable and effective based on adherence rates and drug levels in the body.
What are the potential side effects?
Possible side effects are not detailed here but may include gastrointestinal discomfort from either formulation or irritation from the rectal douche. Side effects related to Tenofovir typically can include nausea, vomiting, diarrhea, dizziness or fatigue.

Experimental Treatment
Group I: Group BExperimental Treatment2 Interventions
Those participants assigned to Group B will start with the on-demand oral F/TDF 200 mg/300 mg sequence for 8 weeks and then after a 2-4 week washout will switch to the rectal TFV 660 mg douche for the next 8 weeks (Period 2).
Group II: Group AExperimental Treatment2 Interventions
Those participants assigned to Group A will start with the rectal TFV 660 mg douche for the first 8 weeks (Period 1) and then after a 2-4 week washout will switch to the on-demand oral F/TDF 200 mg/300 mg sequence for the next 8 weeks (Period 2).
