Current HIV/AIDS Reports
Purpose of Review
The purpose of this study is to summarize recent advances in the use of broadly neutralizing antibodies (bNAbs) as therapeutics in human clinical trials and in non-human primate (NHP) models. We seek to highlight lessons from these studies with an emphasis on consequences to the virus and immune system.
In the past 10 years, advances in HIV-1 trimer structure and B cell isolation methods have precipitated the identification of “new-generation” anti-HIV antibodies with broad and potent neutralization. In the past 2 years, the concept of using these bNAbs as therapeutic tools has moved from NHP models into human clinical trials. These trials have investigated the effects of bNAb infusions into patients chronically infected with HIV-1, while the NHP model has investigated treatment during acute infection.
Through this work, the relationship between in vitro breadth and potency and in vivo clinical effect, although unresolved, is gradually being elucidated. These results emphasize the need for combination antibody therapy.
