How TROGARZO Works

Trogarzo is a CD4-directed blocking antibody that functions as a post-attachment HIV-1 inhibitor. It targets the CD4 receptor on host cells to interfere with the viral infection process. By acting as a fusion inhibitor after the virus has already bound to the cell, the medication prevents HIV-1 from successfully entering and infecting the host cell.
