MTN-014 was a Phase 1, two-arm, crossover, randomized trial in healthy, HIV-negative, sexually active women aged 21 to 45 (inclusive) years to assess the level of tenofovir in both the rectal and vaginal compartments after the rectal and vaginal application of RG tenofovir 1% gel. Women were randomized to the sequence of vaginal or rectal RG tenofovir 1% gel application for two weeks. Blood, vaginal and rectal samples, including tissue, were collected to assess the PK endpoints at the end of the first period of product use. Following a minimum 6-week washout period, women who initially applied the product vaginally were crossed-over to apply product rectally and vice versa. Secondary objectives of MTN-014 study included safety assessment of RG tenofovir 1% gel after 2 weeks of rectal and after 2 weeks of vaginal use. The protocol was amended in May 2013 to incorporate directly observed dosing (DOD) to ensure complete compliance to the study product regimen, critical for this Phase 1 PK clinical trial. Results were presented at the International AIDS Conference (IAS) (HIV Pathogenesis Treatment and Prevention) held on July 19-22, 2015 in Vancouver, Canada. The primary manuscript was published in Journal of Acquired Immune Deficiency Syndromes on June 1, 2018.
