Abstract

The present invention provides methods for treating, preventing or reducing the severity of eosinophilic esophagitis. The methods of the present invention comprise administering to a subject in need thereof a therapeutic composition comprising an interleukin-4 receptor (IL-4Rα) inhibitor such as an anti-IL-4Rα antibody.

Claims (16)

1. A method of treating or ameliorating at least one symptom of eosinophilic esophagitis (EoE) in a subject, the method comprising administering to the subject one or more doses of an interleukin-4 receptor (IL-4R) inhibitor, wherein the IL-4R inhibitor is an antibody or antigen-binding fragment thereof that binds IL-4Rα and comprises a heavy chain complementarity determining region (HCDR)1 comprising the amino acid sequence of SEQ ID NO:3, an HCDR2 comprising the amino acid sequence of SEQ ID NO:4, an HCDR3 comprising the amino acid sequence of SEQ ID NO:5, a light chain complementarity determining region (LCDR)1 comprising the amino acid sequence of SEQ ID NO:6, an LCDR2 comprising the amino acid sequence of SEQ ID NO:7, and an LCDR3 comprising the amino acid sequence of SEQ ID NO:8, and wherein the IL-4R inhibitor is administered to the subject subcutaneously or intravenously.

2. The method of claim 1 , wherein, prior to the onset of treatment the subject exhibits an esophageal eosinophilic infiltration of ≥15 eosinophils per high-power field as measured by esophageal biopsy.

3. The method of claim 1 , wherein the subject is inadequately responsive to treatment with a swallowed topical corticosteroid.

4. The method of claim 1 , wherein the subject is inadequately responsive to diet modification.

5. The method of claim 1 , wherein the subject has concomitant food allergy, atopic dermatitis, asthma, or allergic rhinitis.

6. The method of claim 1 , wherein the subject is an adult.

7. The method of claim 1 , wherein the IL-4R inhibitor is administered subcutaneously.

8. The method of claim 1 , wherein each dose of the IL-4R inhibitor is from 50 mg to 600 mg.

9. The method of claim 8 , wherein each dose of the IL-4R inhibitor is 300 mg.

10. The method of claim 1 , wherein the IL-4R inhibitor is administered once a week, once every two weeks, once every three weeks, or once a month.

11. The method of claim 1 , wherein the IL-4R inhibitor is administered at a dose of 300 mg once a week or once every two weeks.

12. The method of claim 1 , wherein the antibody or antigen-binding fragment thereof comprises a heavy chain variable region (HCVR) comprising the amino acid sequence of SEQ ID NO:1 and a light chain variable region (LCVR) comprising the amino acid sequence of SEQ ID NO:2.

13. The method of claim 1 , wherein the antibody or antigen-binding fragment thereof comprises a heavy chain comprising the amino acid sequence of SEQ ID NO:13 and a light chain comprising the amino acid sequence of SEQ ID NO:14.

14. The method of claim 1 , wherein the antibody or antigen-binding fragment thereof is dupilumab or a bioequivalent thereof.

15. The method of claim 1 , wherein the IL-4R inhibitor is contained in a syringe.

16. The method of claim 1 , wherein the IL-4R inhibitor is contained in a pen delivery device.
