Abstract: The present invention concerns differential therapeutic treatment of cancer patients based on prognostic antigen/antibody profiles used for predicting (prognosticating) a clinical response (efficacy) and/or adverse event to an immunotherapy for treatment of a malignancy in a subject, and for treating or delaying the onset or relapse of a malignancy in a subject.

Abstract: Autoantibodies in biological samples such as serum can result from changes to biomolecules (e.g., proteins, polysaccharides, and lipids) that are associated with disease. Such autoantibodies are useful biomarkers because they frequently appear early in disease and are readily accessible, particularly in biological fluids such as blood and serum. CT antigens are particularly useful for detecting autoantibodies correlated with cancer. Numerous population-based profiles for pluralities of different autoantibody species, at least some of which are specifically reactive with CT antigens, allow for simultaneous assessment of multiple disease-associated analytes is a single test, which can be more effective in diagnostics and drug development than individual profiles. The instant invention provides autoantibody detection array devices that include a plurality of independently selected autoantibody-reactive reagent species, such as full-length CT antigens or the antigenic portions thereof, disposed on a substrate.
