The invention relates to antibodies that are capable of specifically binding tissue factor pathway inhibitor (TFPI), neutralising free TFPI and reducing the clotting time of blood. Furthermore, the invention relates to polynucleotides that encode such antibodies and to cells that comprise the polynucleotides or that express the antibodies of the invention. Such antibodies have utility in the treatment of subjects with a coagulopathy, alone as well as in combination with a second agent.本發明係關於能夠專一性結合組織因子路徑抑制子(TFPI)、中和游離的TFPI及減少血液的凝結時間的抗體。此外,本發明係關於編碼該等抗體之聚核苷酸及包含該等聚核苷酸或表現本發明之抗體的細胞。該等抗體單獨或與第二藥劑結合使用時,對有凝血病變的個體具有治療效用。
