摘要:
A pharmaceutical composition comprising a pharmaceutically acceptable carrier and an isolated antibody or antigen-binding fragment thereof that binds to a free C5a polypeptide, where free C5a is a human polypeptide (C5ah) having the amino acid sequence represented in SEQ ID NO: 1, and wherein the antibody or antigen-binding fragment thereof binds to the free C5ah polypeptide in vitro with a KD that is less than 1.25 x 10-9 M as measured by resonance of surface plasmon (SPR) in the presence of a non-cleaved natural human C5 molar excess: and wherein the antibody or antigen-binding fragment thereof comprises a light chain polypeptide comprising: a light chain CDR1 comprising the amino acid sequence depicted in SEQ ID NO: 20; a light chain CDR2 comprising the amino acid sequence depicted in SEQ ID NO: 21; and a light chain CDR3 comprising the amino acid sequence depicted in SEQ ID NO: 22; and further wherein the antibody or antigen binding fragment thereof comprises a heavy chain polypeptide comprising: a heavy chain CDR1 comprising the amino acid sequence depicted in SEQ ID NO: 28; a heavy chain CDR2 comprising the amino acid sequence depicted in SEQ ID NO: 46; and a heavy chain CDR3 comprising the amino acid sequence depicted in SEQ ID NO: 47.Una composición farmacéutica que comprende un vehículo farmacéuticamente aceptable y un anticuerpo aislado o fragmento de unión a antígeno del mismo que se une a un polipéptido C5a libre, donde C5a libre es un polipéptido de ser humano (C5ah) que tiene la secuencia de aminoácidos representada en la SEC ID Nº: 1, y en la que el anticuerpo o fragmento de unión a antígeno del mismo se une al polipéptido C5ah libre in vitro con una KD que es menor que 1,25 x 10-9 M según se mide por resonancia de plasmones superficiales (SPR) en presencia de un exceso molar de C5 de ser humano natural no escindido: y en el que el anticuerpo o fragmento de unión a antígeno del mismo comprende un polipéptido de cadena ligera que comprende: una CDR1 de
