1. A method of inhibiting alternative complement pathway activation in a mammal, the method comprising:
- administering to the mammal an isolated anti-properdin antibody or antigen binding portion thereof that specifically binds to properdin and inhibits alternative complement pathway activation, wherein the isolated anti-properdin antibody or antigen binding portion thereof (i) comprises at least one CDR having at least 80% sequence identity to SEQ ID NO;
6, SEQ ID NO;
7, SEQ ID NO;
8, SEQ ID NO;
14, SEQ ID NO;
15, or SEQ ID NO;
16, or (ii) competitively inhibits binding of an isolated anti-properdin antibody or antigen binding portion thereof, which comprises at least one CDR having at least 80% sequence identity to SEQ ID;
6, SEQ ID NO;
7, SEQ ID NO;
8, SEQ ID NO;
14, SEQ ID NO;
15, or SEQ ID NO;
16, to properdin.

19. A method of inhibiting alternative pathway activation in a mammal that has, or is at risk of developing, a condition or disease in which the alternative pathway contributes to disease pathology, or exacerbates at least one symptom caused by the condition or disease, the method comprising:
- administering to the mammal an isolated anti-properdin antibody or antigen binding portion thereof that specifically binds to properdin and inhibits alternative complement pathway activation, wherein the isolated anti-properdin antibody or antigen binding portion thereof competitively inhibits binding of an isolated anti-properdin antibody or antigen binding portion thereof, which comprises a heavy chain variable domain which contains the sequences of the three CDRs with the sequences of SEQ ID NOs;
6, 7 and 8, and a light chain variable domain which contains the sequences of the three CDRs with the sequences of SEQ ID NOs;
14, 15 and 16 to properdin. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
