Mechanism of action

PRO 542 binds to the viral surface glycoprotein gp120 and blocks attachment and entry of virus into CD4(+) cells.Unlike currently approved therapies that block viral replication in cells already infected with HIV, PRO 542 is an antibody-like molecule that is designed to target and neutralize the virus in the bloodstream.

Single doses of PRO 542 reduced concentrations of the human immunodeficiency (HIV) in the blood by 60% to 80% in a target population of highly treatment-experienced patients with PRO 542-sensitive virus.
