METHODS AND SYSTEMS FOR SELECTION AND TREATMENT OF PATIENTS WITH INFLAMMATORY DISEASES
Described herein are methods and systems for identifying subjects suitable for treatment with an inhibitor of CD30L activity or expression, such as an anti-CD30L antibody. Methods and systems disclosed herein identify subjects suitable for treatment based on a presence of a genotype that is indicative of a disease or condition in the subject for which an inhibitor of CD30L is a suitable treatment. Exemplary conditions include both Crohn's disease and primary sclerosing cholangitis. Compositions used to detect the genotypes described herein, and methods of using them are also provided.
1 - 8 . (canceled)
9 . A method of treating moderate to severe Crohn's disease (CD) in a subject, the method comprising:
a) identifying a subject with CD as being a carrier of a genotype comprising a polymorphism at least one of rs911605 and rs1006026, the genotype associated with a risk that the subject will develop a moderate to severe form of CD comprising obstructive CD; and
b) administering to the subject a therapeutically effective amount of an inhibitor of CD30 ligand (CD30L) activity or expression.
10 . The method of claim 9 , further comprising determining whether the subject has or will develop at least one of a non-response or a loss-of-response to a standard treatment.
11 . The method of claim 10 , wherein the standard treatment is selected from the group consisting of glucocorticosteriods, anti-TNF therapy, anti-a4-b7 therapy, anti-IL12p40 therapy, Thalidomide, and Cytoxan.
12 . The method of claim 9 , wherein the polymorphism at rs911605 comprises an “A” allele at nucleobase 501 within rs911605 (SEQ ID NO: 1), and wherein the polymorphism at rs1006026 comprises a “G” allele at nucleobase 501 within rs1006026 (SEQ ID NO: 3).
13 . The method of claim 12 , wherein the genotype comprises the polymorphism at rs911605 and the polymorphism at rs1006026.
14 . The method of claim 9 , wherein the inhibitor of CD30 ligand activity is an antibody or an antigen-binding fragment targeting CD30 ligand or CD30, or a combination thereof.
15 - 30 . (canceled)
31 . The method of claim 11 , wherein the anti-a4-b7 therapy is vedolizumab.
32 . The method of claim 11 , wherein the anti-IL12p40 therapy is ustekinumab.
