Methods of Treating Inflammatory Pain
The invention relates to an anti-CGRP antibody for use in the prevention and/or treatment of inflammatory pain and/or symptoms of inflammatory pain, and to a method of treating and/or preventing inflammatory pain and/or symptoms of inflammatory pain using an anti-CGRP antibody.
1 . A method for preventing and/or treating inflammatory pain and/or symptoms of inflammatory pain, comprising peripheral administration to the individual of an effective amount of an anti-CGRP antagonist antibody.
2 . The method according to claim 1 , wherein the medicament is prepared to be peripherally administered.
3 . The method according to claim 1 , wherein the medicament is administered peripherally.
4 . The method according to claim 1 , wherein the medicament is prepared to be administered orally, sublingually, via inhalation, transdermally, subcutaneously, intravenously, intra-arterially, intra-articularly, peri-articularly, locally and/or intramuscularly.
5 . The method according to claim 4 , wherein the medicament is prepared to be administered subcutaneously or intravenously.
6 . The method according to claim 1 , wherein the anti-CGRP antagonist antibody acts peripherally on administration.
7 . The method according to claim 1 , wherein the inflammatory pain is arthritic pain.
8 . The method according to claim 7 , wherein the arthritic pain is osteoarthritis pain.
9 . The method according to claim 1 , wherein the anti-CGRP antagonist antibody:
(a) binds to CGRP;
(b) blocks CGRP from binding to its receptor;
(c) blocks or decreases CGRP receptor activation;
(d) inhibits blocks, suppresses or reduces CGRP biological activity;
(e) increases clearance of CGRP; and/or
(g) inhibits CGRP synthesis, production or release.
10 . The method according to claim 1 , wherein the anti-CGRP antagonist antibody:
(i) is a human antibody,
(ii) is a humanized antibody,
(iii) is a monoclonal antibody,
(iv) binds CGRP with a Kd of 50 nM or less (as measured by surface plasmon resonance at 37° C.); and/or
(v) has a half life in-vivo of at least 7 days.
11 . The method according to claim 1 , wherein the anti-CGRP antagonist antibody specifically binds to the C-terminal region of CGRP.
12 . The method according to claim 10 , wherein the anti-CGRP antagonist antibody specifically recognises the epitope defined by the sequence GSKAF.
13 . The method according to claim 1 , wherein the anti-CGRP antibody comprises a VH domain that is at least 90% identical in amino acid sequence to SEQ ID NO: 1 or 19.
14 . The method according to claim 1 , wherein the anti-CGRP antibody comprises a VL domain that is at least 90% identical in amino acid sequence to SEQ ID NO: 2 or 20.
15 . The method according to claim 14 , wherein the anti-CGRP antibody further comprises a VH domain that is at least 90% identical in amino acid sequence to SEQ ID NO: 1 or 19.
16 . The method according to claim 1 , wherein the anti-CGRP antibody comprises at least one CDR selected from the group consisting of:
(a) CDR H1 as set forth in SEQ ID NO: 3 or 21;
(b) CDR H2 as set forth in SEQ ID NO: 4 or 22;
(c) CDR H3 as set forth in SEQ ID NO: 5 or 23;
(d) CDR L1 as set forth in SEQ ID NO: 6 or 24;
(e) CDR L2 as set forth in SEQ ID NO: 7 or 25;
(f) CDR L3 as set forth in SEQ ID NO: 8 or 26; and
(g) variants of L1, L2 and H2.
17 . The method according to claim 1 , wherein the anti-CGRP antibody comprises a VH domain that is at least 90% identical in amino acid sequence to SEQ ID NO: 1 and a VL domain that is at least 90% identical in amino acid sequence to SEQ ID NO: 2.
18 . The method according to claim 1 , wherein the anti-CGRP antibody comprises a heavy chain produced by the expression vector with ATCC Accession No. PTA-6867.
19 . The method according to claim 1 , wherein the anti-CGRP antibody comprises a light chain produced by the expression vector with ATCC Accession No. PTA-6866.
20 . The method according to claim 1 , wherein the anti-CGRP antibody is produced by the expression vectors with ATCC Accession Nos. PTA-6867 and PTA-6866.
