Prevention of HPV-Associated Anogenital Cancers Using HIV Protease Inhibitors

At a Glance

Human papillomavirus (HPV) is the most commonly sexually transmitted disease in the United States – an estimated 79 million Americans are currently infected— and the number one risk factor for developing anogenital cancers, such as squamous cell carcinoma of the anus (SCCA). In Wisconsin, HPV-positive SCCA disproportionately affects underserved populations, particularly those living with HIV. Once HPV-driven anal pre-cancers are diagnosed, there are few treatment options that are effective or well-tolerated. This project builds on recent findings that show select FDA-approved protease inhibitors, previously used orally to treat HIV infection, can also be used topically to prevent HPV-associated cancers, in particular SCCA.

This team of interdisciplinary researchers will work to determine the molecular mechanisms supporting these effects and repurpose these drugs as an approach for anal cancer prevention in Wisconsin. The long-term goal of this research is to develop a new strategy to prevent HPV-associated cancers, particularly SCCA, especially in high-risk patients such as people living with HIV. This project also includes collaborators from UW–Madison.
