Abstract: Described herein are bispecific antibodies that bind to plasma kallikrein (pKal) and Factor XII and methods of producing and using such bi-specific antibodies for treating diseases or disorders associated with the contact system, e.g., hereditary angioedema or thrombosis. One aspect of the present disclosure is a bispecific antibody, comprising: a first polypeptide that comprises a light chain of a first antibody, the light chain comprising a light chain variable region (VL) and a light chain constant region (CL) (e.g., a kappa light chain or a lambda light chain); and a second polypeptide that comprises a heavy chain of the first antibody, the heavy chain comprising a heavy chain variable region (VH) and a heavy chain constant region (CH).

Abstract: Provided herein are plasma kallikrein binding proteins such as antibodies binding to active plasma kallikrein and methods of using such proteins in treating hereditary angioedema.

Abstract: Methods and assays for determining the activation level of the plasma kallikrein (pKal) system and the uses thereof for assessing the activity of pKal modulators on the pKal system.

Abstract: Methods, kits and compositions for diagnosing and treating autoimmune diseases such as rheumatiodi arthritis, Crohn's disease, and ulcerative colitis.

Abstract: The present disclosure provides methods of evaluating a subject, e.g., a subject at risk for or suffering from a pKal-mediated or bradykinin-mediated disorder, based on values (e.g., percentages) of intact and/or cleaved kininogen in a sample of the subject. Provided methods permit analysis of patients with plasma kallikrein-mediated angioedema (KMA), or other diseases mediated by pKal useful in the evaluation and treatment. Such methods can involve the use of a detection agent that preferentially binds cleaved kininogen or intact kininogen.

Abstract: Disclosed herein are methods for administering an IL-1 or IL-17 antagonist for treating ocular surface disorders, e.g., a dry eye disorder. The antagonists can be administered topically using an opthalmic composition.

Abstract: Methods of treating viral disorders are disclosed.

Abstract: Methods of treating viral disorders are disclosed.

Abstract: The invention relates generally to the treatment and inhibition of immunological complications of the eye. Such complications include unwanted immune responses resulting in an ocular inflammatory disease, resulting from a corneal or retinal graft transplantation or resulting from ocular angiogenesis, particularly ocular neovascularization. The invention relates in particular to the inhibition, treatment, or reversal of immune-system driven rejection of grafted corneal or retinal tissue or cells in a recipient host and to the treatment or inhibition of ocular inflammatory disease or ocular neovascularization in a host.

Abstract: Methods and compositions for attenuating or mitigating; suppressing; preventing; delaying onset of; or, reversing exogenous protein inhibitor syndromes, exemplified by clotting factor (e.g., Factor VIII) inhibitor syndromes. The described methods use a CD40:CD154 binding interrupter, such as a CD154 blocking agent, to attenuate or ameliorate counter-adaptive, bioinhibitory humoral immunity directed against an exogenous protein of therapeutic value.
