Abstract
Purpose of review: Fostemsavir is a recently Food and Drug Administration-approved HIV-1 attachment inhibitor that binds to HIV-1 gp120 and prevents viral attachment to the cellular CD4 receptor. Here, we review the pharmacology, efficacy, tolerability, and resistance profile of fostemsavir.
Recent findings: Fostemsavir is well tolerated and maintains virologic activity in individuals harboring multidrug-resistant HIV-1. In conjunction with optimal background therapy, a majority of heavily treatment-experienced clinical trial participants treated with fostemsavir achieved virologic suppression.
Summary: The approval of fostemsavir represents an important advance for individuals harboring multidrug resistant HIV-1 due to its novel mechanism of action and lack of cross-resistance to other antiretrovirals. Further study will better define the role of resistance testing for fostemsavir and fostemsavir's potential role outside of salvage therapy in heavily treatment-experienced individuals.
