Method of reducing pruritis using IL-31 monoclonal antibodies
The present invention relates to methods of treating pruritic diseases, including but not limited to Contact dermatitis, Atopic Dermatitis, Drug induced delayed type cutaneous allergic reactions, Toxic epidermal necrolysis, Cutaneous T cell Lymphoma, Bullous pemphigoid, Alopecia wereata, Vitiligo, Acne Rosacea, Prurigo nodularis, Scleroderma, Herpes simplex virus, or combination thereof by administering IL-31 monoclonal antibodies. The invention further provides the hybridomas that generate the monoclonal antibodies.
1. A method of reducing pruritus in a mammal comprising administering to the mammal a therapeutically effective amount of a monoclonal antibody or antigen-binding fragment thereof that is capable of competing for binding to a polypeptide consisting of amino acid residues 27 to 164 of SEQ ID NO:2 with the monoclonal antibody produced by the hybridoma deposited with the American Type Culture Collection having ATCC Patent Deposit Designation selected from the group consisting of:
a) ATCC Patent Deposit Designation PTA-6815;
b) ATCC Patent Deposit Designation PTA-6816;
c) ATCC Patent Deposit Designation PTA-6829;
d) ATCC Patent Deposit Designation PTA-6830;
e) ATCC Patent Deposit Designation PTA-6831;
f) ATCC Patent Deposit Designation PTA-6871;
g) ATCC Patent Deposit Designation PTA-6872;
h) ATCC Patent Deposit Designation PTA-6875; and
i) ATCC Patent Deposit Designation PTA-6873, and
wherein after administration of the monoclonal antibody or antigen-binding fragment thereof the pruritus is reduced.
2. The method of claim 1 , wherein the monoclonal antibody or antigen-binding fragment thereof neutralizes the signal transduction of the polypeptide through its cognate receptor.
3. The method of claim 1 , wherein the monoclonal antibody or antigen-binding fragment thereof further comprises a radionuclide, enzyme, substrate, cofactor, fluorescent marker, chemiluminescent marker, peptide tag, magnetic particle, or toxin.
4. The method of claim 1 , wherein the monoclonal antibody or antigen-binding fragment thereof is conjugated to a polyethylene glycol.
5. The method of claim 1 , wherein the monoclonal antibody or antigen-binding fragment thereof is chimeric, humanized, a Fab or a F(ab′) 2 .
6. The method of claim 1 , wherein the monoclonal antibody or antigen-binding fragment thereof is the monoclonal antibody produced by the hybridoma deposited with the American Type Culture Collection having ATCC Patent Deposit Designation PTA-6815.
7. The method of claim 6 , wherein the monoclonal antibody or antigen-binding fragment thereof is humanized.
8. A method of reducing pruritus in a mammal comprising administering to the mammal a therapeutically effective amount of a monoclonal antibody or antigen-binding fragment thereof, wherein the monoclonal antibody is produced by the hybridoma deposited with the American Type Culture Collection having ATCC Patent Deposit Designation PTA-6815 and is humanized, wherein the pruritus is a symptom of atopic dermatitis, and wherein after administration of the monoclonal antibody or antigen-binding fragment thereof the pruritus is reduced.
