Abstract: The disclosure is directed to novel predictive methods and personalized therapies for treating dry eye disease (DED). Specifically, this disclosure relates to methods of treating a patient having DED by selectively administering a TNF? antagonist, e.g., a TNF? antibody, such as LME636, to the patient on the basis of that patient being genetically predisposed to have a favorable response to treatment with the TNF? antagonist. Also disclosed herein are transmittable forms of information, diagnostic methods, and kits useful in predicting the likelihood that a patient having DED will respond to treatment with a TNF? antagonist, e.g., a TNF? antibody, such as LME636.
