MTN-037

MTN-037 was a Phase 1, open-label, sequential dose/volume escalation study designed to evaluate the safety and pharmacokinetics of PC-1005 (MIV-150/zinc acetate/carrageenan gel) when administered rectally. The study enrolled 12 healthy, HIV-uninfected men and women (cis or transgender) who are 18 years of age or older and who have a history of consensual receptive anal intercourse (RAI). PC-1005 was designed to be a dual compartment gel (vaginal or rectal use), with potential activity against HIV-1, herpes simplex virus type 2 (HSV-2), and human papilloma virus (HPV). MTN-037 is the first study to assess the safety and PK of PC-1005 gel applied rectally.

Study product was rectally administered by clinic staff. Each participant received a total of three doses of PC-1005 (1st dose = 4mL, 2nd dose = 16mL, and 3rd dose = 32mL), with a 2-6-week washout period between each dose. Study endpoint assessments were performed within 24-48 hours of each of the three product applications. It is hypothesized that PC-1005 gel will be safe when applied to the rectum and well-tolerated among healthy men and women (cis or transgender).

The study completed follow-up on April 19, 2019. Primary results were presented at the HIV Research for Prevention (HIVR4P) conference held virtually on January 27-28 and February 3-4 in 2021. The primary manuscript is currently in development.
