Methods of using a bispecific antibody that recognizes coagulation factor IX and/or activated coagulation factor IX and coagulation factor X and/or activated coagulation factor X

摘要

An objective of the present invention is to provide an effective pharmaceutical composition or a dosage regimen for preventing and/or treating bleeding, a disease accompanying bleeding, or a disease caused by bleeding. The inventors discovered that by administering a pharmaceutical composition comprising a bispecific antigen-binding molecule that recognizes (a) blood coagulation factor IX and/or activated blood coagulation factor IX and (b) blood coagulation factor X and/or activated blood coagulation factor X according to a given dosage regimen, bleeding, a disease accompanying bleeding, or a disease caused by bleeding can be prevented and/or treated more effectively.
