Alleles and polymorphisms predictive of responsiveness to biologic therapy in psoriasis

摘要

The invention provides methods for predicting responsiveness to a biologic agent in a subject suffering from psoriasis. The methods involve assaying for the presence or absence of an allele or polymorphism in the subject that is predictive of responsiveness to biologic therapy, such as an HLA-Cw6 allele, a TNFα 238 polymorphism or a TNFα 308 polymorphism. The methods can further comprise selecting a treatment regimen with a biologic agent in a psoriasis subject based upon presence or absence of the allele or polymorphism in the subject. The methods can further comprise administering a biologic agent to the subject according to the selected treatment regimen. Kits that include means for assaying an allele or polymorphism that is predictive of responsiveness to biologic therapy for psoriasis are also provided. Methods of preparing and using databases, and computer program products therefore, for selecting a psoriasis subject for treatment with a biologic agent are also provided.
