Compositions and methods for treatment of diabetic macular edema
View Patent ↗Disclosed herein are compositions comprising one or more antibodies that specifically bind active plasma kallikrein (e.g., human plasma kallikrein) and methods of using such compositions for the treatment of retinal diseases, such as diabetic macular edema.
1. A method for treating a retinal disease in a subject, the method comprising:
administering an effective amount of a composition comprising an antibody to a subject in need thereof, wherein
the antibody comprises:
a heavy chain variable region comprising a complementarity determining region (CDR) 1 set forth as HYIMM (SEQ ID NO: 5), a CDR2 set forth as GIYSSGGITVYADSVKG (SEQ ID NO: 6), and a CDR3 set forth as RRIGVPRRDEFDI (SEQ ID NO: 7); and
a light chain variable region comprising a CDR1 set forth as RASQSISSWLA (SEQ ID NO: 8), a CDR2 set forth as KASTLES (SEQ ID NO: 9), and a CDR3 set forth as QQYNTYWT (SEQ ID NO: 10);
wherein the retinal disease is selected from the group consisting of diabetic macular edema (DME), age-related macular degeneration (AMD), and retinal vein occlusion (RVO).
2. The method of claim 1 , wherein the retinal disease is diabetic macular edema.
3. The method of claim 1 , wherein the antibody is a full-length antibody or an antigen-binding fragment thereof.
4. The method of claim 1 , wherein the antibody is a human antibody or a humanized antibody.
5. The method of claim 1 , wherein the antibody comprises the HC variable domain set forth as SEQ ID NO: 3, and the LC variable domain set forth as SEQ ID NO: 4.
6. The method of claim 5 , wherein the antibody is a Fab.
7. The method of claim 1 , wherein the antibody is a Fab comprising a HC variable region set forth as SEQ ID NO:3, and a LC variable region set forth as SEQ ID NO:4.
8. The method of claim 1 , wherein the composition is administered via intravitreal injection.
9. The method of claim 1 , wherein the antibody is the only active agent administered to the subject for treating the retinal disease.
