                                        Comment: Ibalizumab was originally reported as anti-CD4 monoclonal antibody 5A8 by Burkly et al. (1992 ) [1]. It is a non-immunosuppressive, humanised monoclonal antibody that acts as an HIV entry inhibitor [2,4].  Anti-HIV activity of TNX-355 (later to be assigned the INN ibalizumab) in patients was reported in 2004 [5].
