Mouse surrogate anti-FcRn mAb in an immune thrombocytopenia (ITP) disease model
“The ability of a mouse surrogate (4470) of rozanolixizumab to increase clearance of IgG was evaluated in a mouse disease model of immune thrombocytopenia (ITP).”
EMA: adequate evidence of MoA, supported by disease models though none of gMG
“Overall, the primary PD studies provided adequate evidence of MoA, which is considered well-established for rozanolixizumab both in vitro and in vivo and supported by meaningful effects as observed in in vivo disease models, however not in a model of gMG.”
