Factor IX/factor IXa activating antibodies and antibody derivatives
An antibody or antibody derivative against factor IX/activated factor IX (FIXa) which increases the procoagulant activity of FIXa.
1. A method for treating patients afflicted with hemophilia A comprising administering to said patients a pharmaceutically effective amount of a pharmaceutical preparation comprising:
an antibody that binds factor IX/factor IXa and increases the procoagulant activity of FIXa, wherein said antibody is produced by a hybridoma selected from the group consisting of cell lines having ECACC deposit numbers 99090924, 99090925, 99090926, 99121614, 99121615, 99121616, 99121617, 99121618, 99121619 and 99121620; and
a pharmaceutically acceptable carrier.
2. The method of claim 1 , additionally comprising the step of selecting hemophilia inhibitor patients.
3. A method for increasing the amidolytic activity of factor IXa comprising administering an antibody that binds factor IX/factor IXa and increases the procoagulant activity of FIXa, wherein said antibody is produced by a hybridoma selected from the group consisting of cell lines having ECACC deposit numbers 99090924, 99090925, 99090926, 99121614, 99121615, 99121616, 99121617, 99121618, 99121619 and 99121620.
4. A method for treating patients afflicted with hemophilia A comprising administering to said patients a pharmaceutically effective amount of a pharmaceutical preparation comprising:
an antibody or antibody fragment that binds factor IX/factor IXa and increases the procoagulant activity of FIXa, wherein the variable region of said antibody or antibody fragment comprises amino acids 1-119 and amino acids 135-242 set forth in SEQ ID NO:82; and
a pharmaceutically acceptable carrier.
5. A method for treating patients afflicted with hemophilia A comprising administering to said patients a pharmaceutically effective amount of a pharmaceutical preparation comprising:
an antibody or antibody fragment against factor IX/factor IXa which increases the procoagulant activity of FIXa, wherein the variable region of said antibody or antibody fragment comprises amino acids 1-121 and amino acids 137-249 as set forth in SEQ ID NO:84; and
a pharmaceutically acceptable carrier.
6. A method for treating patients afflicted with hemophilia A comprising administering to said patients a pharmaceutically effective amount of a pharmaceutical preparation comprising:

a pharmaceutically acceptable carrier.
7. A method for increasing the amidolytic activity of factor IXa comprising administering an antibody or antibody an antibody or antibody fragment against factor IX/factor IXa which increases the procoagulant activity of FIXa, wherein the variable region of said antibody or antibody fragment comprises amino acids 1-119 and amino acids 135-242 set forth in SEQ ID NO:82.
8. A method for increasing the amidolytic activity of factor IXa comprising administering an antibody or antibody fragment that binds factor IX/factor IXa and increases the procoagulant activity of FIXa, wherein the variable region of said antibody or antibody fragment comprises amino acids 1-121 and amino acids 137-249 as set forth in SEQ ID NO:84.
9. A method for increasing the amidolytic activity of factor IXa comprising administering an antibody or antibody fragment that binds factor IX/factor IXa and increases the procoagulant activity of FIXa, wherein the variable region of said antibody or antibody fragment comprises amino acids 1-122 and amino acids 138-249 as set forth in SEQ ID NO:86.
