Description

Tosatoxumab (AR-301; KBSA301) is a human immunoglobulin G1 monoclonal antibody that specifically neutralizes alpha-toxin (alpha-hemolysin; Hla) of S. aureus. Tosatoxumab binds to an N-terminal epitope of alpha-toxin, thereby preventing functional toxin pore oligomerisation. Tosatoxumab has the potential for passive immunotherapy in the S. aureus pneumonia as an adjunctive therapy to standard antibiotic agent.
