Methods for treating systemic lupus erythematosus with an anti-apolipoprotein B antibody
Described herein are peptides and antibodies for prevention and/or therapeutic treatment of mammals, including humans, against systemic lupus erythematosus, as well as diagnosing the presence or absence of antibodies related to increased or decreased risk of developing SLE and/or to disease grading, staging, and/or prognosis.
1. A method for treating systemic lupus erythematosus (SLE) in a subject in need thereof by passive immunization, comprising administering a therapeutically or prophylactically effective amount of an antibody that binds at least one oxidized fragment of apolipoprotein B100 (ApoB100), so as to treat SLE, wherein the antibody comprises a variable heavy region (V H ) and a variable light region (V L ), wherein the V H region comprises the sequence set forth in SEQ ID NO: 324 and the variable light region (V L ) comprises the sequence set forth in SEQ ID NO: 325.
2. The method of claim 1 , wherein the antibody is a human antibody.
3. The method of claim 1 , wherein the V H region consists of the sequence set forth in SEQ ID NO: 324 and the variable light region (V L ) consists of the sequence set forth in SEQ ID NO: 325.
4. A method for treating, reducing the severity of, slowing progression of or inhibiting systemic lupus erythematosus (SLE) in a subject in need thereof, comprising:
administering to the subject an effective amount of an antibody or antibody fragment,
wherein the antibody or antibody fragment comprises heavy chain complementarity determining region (HCDR) 1 (HCDR1), HCDR 2 (HCDR2) and HCDR 3 (HCDR3) whose sequences comprise SEQ ID NOs: 318, 319 and 320, respectively, and light chain complementarity determining region (LCDR) 1 (LCDR1), LCDR 2 (LCDR2) and LCDR 3 (LCDR3) whose sequences comprises SEQ ID NOs: 321, 322 and 323, respectively.
5. The method of claim 4 , wherein the antibody or antibody fragment is capable of binding to a fragment of apolipoprotein B100 (ApoB100), and the fragment of ApoB100 comprises an amino acid sequence of SEQ ID NO:45 and is an aldehyde derivative.
6. The method of claim 4 , wherein the antibody or antibody fragment comprises a variable heavy region (V H ) of SEQ ID NO: 324, a variable light region (V L ) of SEQ ID NO: 325, or both.
7. The method of claim 6 , wherein the antibody or antibody fragment comprises a heavy chain of SEQ ID NO: 316, a light chain of SEQ ID NO: 317, or both.
8. The method of claim 4 , wherein the antibody is orticumab and is administered intravenously at an initial dose of at least 5 mg/kg, followed by a plurality of subsequent doses, each at least 2 mg/kg/week, at least 2.5 mg/kg/two weeks, or at least 6 mg/kg/month.
9. The method of claim 8 , wherein the subsequent doses are administered over at least 2 weeks, 3 weeks, or 1 month.
10. The method of claim 4 , wherein the subject is a human, the antibody is orticumab, and the orticumab is administered subcutaneously at a dose of about 330 mg/month for about 3, 4, 5, 6, 7, 8, 9, 10, 11 or 12 months.
11. The method of claim 4 , wherein the antibody or antibody fragment is administered at 10-150 μg/kg, 150-750 μg/kg, 1-5 mg/kg, 5-10 mg/kg, 10-15 mg/kg, 15-20 mg/kg, 20-25 mg/kg, 25-50 mg/kg or 50-75 mg/kg.
12. The method of claim 4 , further comprising selecting a subject exhibiting symptoms of SLE or a subject who has been diagnosed with SLE.
13. The method of claim 4 , comprising administering an anti-malarial therapeutic, a corticosteroid, mycophenolate mofetil, azathioprine, cyclophosphamide, cyclosporine, leflunomide, or methotrexate in combination with the antibody or antibody fragment to the subject.
14. A method for treating, reducing the severity of, slowing progression of or inhibiting atherosclerosis in a subject exhibiting symptoms of or having been diagnosed with systemic lupus erythematosus (SLE), comprising:
administering to the subject an effective amount of an antibody or antibody fragment capable of binding to a fragment of apolipoprotein B100 (ApoB100),
wherein the fragment of ApoB100 comprises an amino acid sequence of SEQ ID NO: 45 or an active site thereof, and wherein the antibody or antibody fragment comprises heavy chain complementarity determining region (HCDR) 1 (HCDR1), HCDR 2 (HCDR2) and HCDR 3 (HCDR3) whose sequences comprise SEQ ID NOs: 318, 319 and 320, respectively, and one, two or three light chain complementarity determining region (LCDR) 1 (LCDR1), LCDR 2 (LCDR2) and LCDR 3 (LCDR3) whose sequences comprise SEQ ID NOs: 321, 322 and 323, respectively.
15. The method of claim 14 , wherein the antibody or antibody fragment comprises a variable heavy region (V H ) of SEQ ID NO: 324, a variable light region (V L ) of SEQ ID NO: 325, or both.
16. The method of claim 14 , wherein the antibody or antibody fragment comprises a heavy chain of SEQ ID NO: 316, a light chain of SEQ ID NO: 317, or both.
17. The method of claim 14 , wherein the subject exhibits symptoms of atherosclerosis and SLE before the administration, and after the administration the subject has reduced plaque volume in artery.
18. The method of claim 14 , wherein the antibody is orticumab and is administered intravenously at an initial dose of at least 5 mg/kg, followed by a plurality of subsequent doses, each at least 2 mg/kg/week, at least 2.5 mg/kg/two weeks, or at least 6 mg/kg/month.
19. The method of claim 14 , wherein the subject is a human, the antibody is orticumab, and the orticumab is administered subcutaneously at a dose of about 330 mg/month for about 3, 4, 5, 6, 7, 8, 9, 10, 11 or 12 months.
20. The method of claim 14 , wherein the atherosclerosis is accelerated atherosclerosis.
