Rectal Safety and Acceptability Study of Tenofovir 1% Gel

Summary

MTN-007 is a Phase 1, randomized, blinded, placebo-controlled safety and acceptability study of vaginally formulated tenofovir 1% gel (a reduced-glycerin formulation), when applied rectally. The primary objective of this study is to assess the safety of vaginally formulated tenofovir 1% gel when applied rectally. After completing screening and baseline evaluation, eligible participants will be randomized to receive tenofovir 1% gel, 2% nonoxynol-9 gel (N-9) or placebo gel. The study will also include a no treatment arm. There will be 15 participants in each arm. Participants will return to the clinic, where they will self-administer a single dose of the study gel under observation. Within approximately 30 minutes, lavage, stool, and rectal biopsy specimens will be obtained. After a one-week recovery period, participants will return to the clinic for assessment. If no significant adverse events (AEs) are reported they will begin to self-administer once-daily outpatient doses of the study gel for 7 days. Participants will return to clinic for evaluation and specimen collection after completion of 7 days of daily dosing.
