About SP-01A

SP-01A is an HIV oral entry inhibitor drug. In order for viruses to reproduce, they must infect or hi-jack a cell, and use it to make new viruses. Just as your body is constantly making new skin cells, or new blood cells, each cell often makes new proteins in order to stay alive and to reproduce itself. Viruses hide their own DNA in the DNA of the cell, and then, when the cell tries to make new proteins, it accidentally makes new viruses as well. HIV mostly infects cells in the immune system.

Clinical studies to date suggest that SP-01A prevents HIV from entering cells by inhibiting HIV-1 viral replication through a novel mechanism that is unique to any antiviral drug. SP-01A reduces intracellular cholesterol and corticosteroid biosynthesis, which causes the inability of lipid rafts in the cellular membrane to organize, ultimately preventing fusion of an HIV receptor and both the CCR5 and CXCR4 cellular receptors.
