Antagonist anti-CD28 antibodies prevent T cell costimulation and differentiate from CTLA4Ig
since they cannot block CTLA-4 and PDL-1 coinhibitory signals. They demonstrated efficacy
in suppressing effector T cells while enhancing regulatory T cells function and immune
tolerance. However, anti-CD28 antibodies devoid of immunotoxicity and with a good
pharmacokinetic profile have not yet been developed. Here, we describe FR104, a novel
humanized pegylated anti-CD28 Fab′ antibody fragment presenting a long elimination half …
