Ovr115 antibody compositions and methods of use
The invention encompasses a method of inhibiting growth of tumor cells in vivo, comprising contacting the cells with an anti-Ovr115 antibody, or antigen binding fragment thereof. This invention also encompasses a method of alleviating an Ovr115-expressing cancer in a mammal, comprising administering a therapeutically effective amount of an anti-Ovr115 antibody, or antigen binding fragment thereof, to the mammal.
1. A method for inhibiting growth of tumor cells in vivo, comprising contacting the cells with an anti-Ovr115 antibody, or antigen binding fragment thereof, in an amount effective to inhibit growth of the tumor cells, wherein the antibody, or antigen binding fragment thereof, inhibits Ovr115 activity and wherein the antibody, or antigen binding fragment thereof, binds an epitope consisting of the cleavage peptide RVVGG (SEQ ID NO:3).
2. The method of claim 1 , wherein the inhibited Ovr115 activity is selected from the group consisting of protease activity, LDLa receptor binding and scavenger receptor binding or the Ovr115 activity is inhibited by inhibiting cleavage of the Ovr115 proenzyme.
3. The method of claim 1 , wherein the tumor cells express Ovr115.
4. The method of claim 1 , wherein the antibody, or antigen binding fragment thereof, is a human, humanized or chimeric antibody, or antigen binding fragment thereof, which competes for binding with an antibody, or antibody fragment thereof.
5. A method of inhibiting tumor growth in a mammal comprising administering a therapeutically effective amount of an anti-Ovr115 antibody, or antigen binding fragment thereof, to the mammal wherein the antibody, or antigen binding fragment thereof, inhibits Ovr115 activity and wherein the antibody, or antigen binding fragment thereof, binds an epitope consisting of the cleavage peptide RVVGG (SEQ ID NO:3).
6. The method of claim 5 , wherein the inhibited Ovr115 activity is selected from the group consisting of protease activity, LDLa receptor binding and scavenger receptor binding or the Ovr115 activity is inhibited by inhibiting cleavage of the Ovr115 proenzyme.
7. The method of claim 5 , wherein the tumor expresses Ovr115.
8. The method of claim 5 , wherein the antibody, or antigen binding fragment thereof, is a human, humanized or chimeric antibody, or antigen binding fragment thereof.
9. A method of alleviating an Ovr115-expressing cancer in a mammal and/or increasing survival of a mammal with an Ovr115-expressing cancer, comprising administering a therapeutically effective amount of an anti-Ovr115 antibody, or antigen binding fragment thereof, to the mammal wherein the antibody, or antigen binding fragment thereof, inhibits Ovr115 activity and wherein the antibody, or antigen binding fragment thereof, binds an epitope consisting of the cleavage peptide RVVGG (SEQ ID NO:3).
10. The method of claim 9 , wherein the inhibited Ovr115 activity is selected from the group consisting of protease activity, LDLa receptor binding and scavenger receptor binding or the Ovr115 activity is inhibited by inhibiting cleavage of the Ovr115 proenzyme.
11. The method of claim 9 , wherein the antibody, or antigen binding fragment thereof, is a human, humanized or chimeric antibody, or antigen binding fragment thereof.
