Abstract: Described herein are methods for treating rheumatoid arthritis by determining whether a subject having rheumatoid arthritis will respond to an anti-TNF-alpha therapy based on the number of innate and adaptive immune cells in a sample from the subject prior to treatment.

Abstract: Methods disclosed herein include an improved technique for comparing a glycosylation profile of a first protein (e.g., an innovator protein drug) with a glycosylation profile of a second protein (e.g., a corresponding biogeneric/biosimilar). For example, a method of manufacture can include providing or obtaining a batch of a test glycoprotein drug substance, using mass spectrometry to acquire a test oxonium ion profile from a sample of the test glycoprotein drug substance batch, comparing the test oxonium ion profile to a corresponding target oxonium ion profile of a target glycoprotein drug product, and processing the batch of the test glycoprotein drug substance as a drug product if the difference between the test oxonium ion profile and the corresponding target oxonium ion profile is tolerable, or taking an alternative action if the difference between the test oxonium ion profile and the target oxonium ion profile is not tolerable.

Abstract: The present invention features methods of treating a subject having an autoimmune disease and/or inflammation including determining the genotype, and/or the glycophenotype of the subject and administering to the subject an Fc-activity modulating agent or an anti-TNF? agent based on the genotype and/or the glycophenotype of the subject. The invention also features methods of predicting the responsiveness of a patient to an anti-TNF? treatment by identifying a patient having inflammation or an autoimmune disease, determining the genotype, or glycophenotype of the subject, and selecting the patient for treatment with an Fc-activity modulating agent or an anti-TNF? agent based on the genotype and/or the glycophenotype of the subject.

Abstract: A method of making a glycoprotein having a selected glycostructure.
