Anti-NGF antibodies that selectively inhibit the association of NGF with TrkA, without affecting the association of NGF with p75
View Patent ↗This invention pertains to NGF antagonists including antibodies and antibody fragments thereof having binding specificity to human Nerve Growth Factor (“NGF”), and methods of treating pain. Methods of treating pain or eliciting an analgesic effect in an individual comprising administering an effective amount of an NGF antagonist inhibits the association of NGF with TrkA without inhibiting the association of NGF with p75. The methods may further comprise administering an effective amount of a second anti-human NGF antibody or fragment thereof which inhibits the association of NGF with p75, that may further also inhibit the association of NGF with TrkA.

4. The antibody or antibody fragment of claim 1 , wherein said antibody or antibody fragment comprises (i) a V H chain polypeptide at least 95% identical to the amino acid sequence of SEQ ID NO:143 or SEQ ID NO:144, and/or (ii) a V L chain polypeptide at least 95% identical to the amino acid sequence of SEQ ID NO:141 or SEQ ID NO:142.
5. The antibody or antibody fragment of claim 1 , wherein said antibody or antibody fragment comprises (i) a V H chain polypeptide identical to the amino acid sequence of SEQ ID NO:143 or SEQ ID NO:144, and/or (ii) a V L chain polypeptide identical to the amino acid sequence of SEQ ID NO:141 or SEQ ID NO:142.
6. The antibody or antibody fragment of claim 1 , wherein said antibody or antibody fragment thereof is aglycosylated.
7. The antibody or antibody fragment of claim 1 , wherein said antibody or antibody fragment thereof comprises an F c region that has been modified to alter effector function, half-life, proteolysis, and/or glycosylation.
8. The antibody or antibody fragment of claim 1 , wherein said antibody or antibody fragment thereof is a human, humanized, single chain or chimeric antibody.
9. The antibody or antibody fragment of claim 1 , wherein said antibody or antibody fragment thereof specifically binds to NGF expressing human cells and/or to circulating soluble NGF molecules in vivo.
10. The antibody or antibody fragment of claim 9 , wherein said antibody or antibody fragment thereof specifically binds to NGF expressed on or by human cells in a patient with a disease associated with cells that bind NGF.
11. The antibody or antibody fragment of claim 10 , wherein the disease is inflammatory pain, post-operative incision pain, complex regional pain syndrome, cancer pain, primary or metastatic bone cancer pain, fracture pain, osteoporotic fracture pain, pain resulting from burn, osteoporosis, gout joint pain, pain associated with sickle cell crises, hepatocellular carcinoma, breast cancer, liver cirrhosis, neurogenic pain, neuropathic pain, nociceptic pain, trigeminal neuralgia, post-herpetic neuralgia, phantom limb pain, fibromyalgia, menstrual pain, ovarialgia, reflex sympathetic dystrophy, osteoarthritis or rheumatoid arthritis pain, lower back pain, diabetic neuropathy, sciatica, or migraine.
12. The antibody or antibody fragment of claim 1 , wherein said antibody or antibody fragment thereof is directly or indirectly attached to a detectable label or a therapeutic agent.
13. The antibody or antibody fragment of claim 1 , wherein the antibody or antibody fragment thereof is a chimeric antibody comprising a human F c region.
14. The antibody or antibody fragment of claim 13 , wherein the human F c region is selected from the group consisting of IgG1, IgG2, IgG3, IgG4, IgG5, IgG6, IgG7, IgG8, IgG9, IgG10, IgG11, IgG12, IgG13, IgG14, IgG15, IgG16, IgG17, IgG18 and IgG19.
15. The antibody or antibody fragment of claim 1 , wherein said antibody inhibits the association of NGF with TrkA, but does not inhibit the association of NGF with p75.
16. The antibody or antibody fragment of claim 1 , wherein said antibody or antibody fragment thereof binds to NGF with an off-rate (K off ) of less than or equal to 10 −4 S −1 , 5×10 −5 S −1 , 10 −5 S −1 , 5×10 −6 S −1 , 10 −6 S −1 , 5×10 −7 S −1 , or 10 −7 S −1 .
17. The antibody or antibody fragment of claim 1 , wherein said antibody or antibody fragment further comprises an effector moiety.
18. The antibody or antibody fragment of claim 17 , wherein the effector moiety is a detectable moiety or a functional moiety.
19. The antibody or antibody fragment of claim 18 , wherein said detectable moiety is a fluorescent dye, an enzyme, a substrate, a bioluminescent material, a radioactive material, or a chemiluminescent material.
20. The antibody or antibody fragment of claim 18 , wherein said functional moiety is streptavidin, avidin, biotin, a cytotoxin, a cytotoxic agent, or a radioactive material.
