Method of treating atherosclerosis
The present disclosure relates to a method of treating or preventing atherosclerosis in a subject by administering an inhibitor of FXII.
1. A method for treating atherosclerosis in a subject, comprising administering to the subject an effective amount of an inhibitor of Factor XII (FXII), wherein the inhibitor of FXII is an anti-FXII antibody or antigen binding fragment thereof comprising:
(i) a V H comprising the polypeptide sequence set forth in SEQ ID NO: 18 and a V L comprising the polypeptide sequence set forth in SEQ ID NO: 19; or
(ii) a heavy chain comprising the polypeptide sequence set forth in SEQ ID NO: 20 and a light chain comprising the polypeptide sequence set forth in SEQ ID NO: 21.
2. The method of claim 1 , wherein the method (i) reduces atherosclerotic plaques in the subject, (ii) stabilizes vulnerable atherosclerotic plaques in the subject, and/or (iii) reduces the risk of atherosclerotic plaque rupture in the subject.
3. The method of claim 1 , wherein the anti-FXII antibody or antigen binding fragment thereof is an IgG antibody.
4. The method of claim 1 , wherein the inhibitor of FXII is linked to a fusion partner comprising polyethylene glycol (PEG) or a half-life enhancing polypeptide, and wherein the half-life enhancing polypeptide is selected from the group consisting of albumin, afamin, alpha-fetoprotein, vitamin D binding protein, and human albumin.
5. The method of claim 4 , wherein the half-life enhancing polypeptide is linked to the inhibitor of FXII via a linker.
6. The method of claim 3 , wherein the inhibitor of FXII is a fusion protein comprising human albumin linked to an inhibitor of FXII via a linker peptide.
7. The method of claim 1 , wherein the inhibitor of FXII is administered to the subject intravenously, subcutaneously, or intrathecally.
8. The method of claim 1 , wherein the inhibitor of FXII is administered to the subject:
(i) in a single dose;
(ii) in a plurality of doses; or
(iii) as a continuous dose.
9. The method of claim 1 , wherein the inhibitor of FXII is administered to the subject at a concentration of from about 0.01 to about 100 mg/kg body weight.
10. The method of claim 1 , wherein the subject suffers from diabetes and/or obesity.
11. The method of claim 1 , wherein the inhibitor of FXII is administered to the subject at a concentration of from about 1 to about 20 mg/kg body weight.
12. An anti-Factor XII (FXII) antibody or antigen binding fragment thereof, comprising:
(i) a V H comprising the polypeptide sequence set forth in SEQ ID NO: 18 and a V L comprising the polypeptide sequence set forth in SEQ ID NO: 19; or
(ii) a heavy chain comprising the polypeptide sequence set forth in SEQ ID NO: 20 and a light chain comprising the polypeptide sequence set forth in SEQ ID NO: 21.
13. A kit comprising:
(a) at least one inhibitor of FXII comprising the anti-FXII antibody or antigen binding fragment thereof of claim 12 ;
(b) instructions for using the kit for treating or preventing atherosclerosis in a subject; and
(c) optionally, at least one further therapeutically active compound or drug.
