Abstract: The disclosure relates to antibodies that bind FcRn and methods of using these antibodies.

Abstract: Provided herein are methods and kits for analyzing a biological sample obtained from a subject having, suspected of having, or being at risk for a disease associated with the contact activation system.

Abstract: Methods for differentiating full-length high molecular weight kininogen (HMWK) and cleaved HMWK in a sample are provided herein. Such methods may comprise treating a biological sample with a protease to generate a plurality of digested peptides, and measuring one or more signature peptides, which are indicative of cleaved HMWK and/or full-length HMWK.

Abstract: Disclosed herein are evacuated blood collection tubes comprising protease inhibitor cocktails in liquid form and uses thereof for assessing features associated with the contact system in a subject, including the endogenous level of contact system activation, the endogenous level of a drug that targets a component of contact system during treatment, and/or the immunogenicity of such a drug.

Abstract: Provided herein are methods for treating acute respiratory distress syndrome (ARDS), such as ARDS associated with respiratory virus infection, involving administering an inhibitor of the contact activation pathway. Also provided herein are methods for treating pneumonia and methods for reducing and/or preventing thrombosis associated with extracorporeal membrane oxygenation (ECMO) in a subject having acute respiratory distress syndrome (ARDS), involving administering an inhibitor of the contact activation pathway.

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: Plasma kallikrein binding proteins and methods of using such proteins are described.

Abstract: Aspects of the present application provide for methods and apparatuses for modeling, simulating, and treating hereditary angioedema (HAE). According to some aspects, a quantitative systems pharmacology (QSP) model is provided for simulating the efficacy of drug intervention under context of HAE pathophysiology. The QSP model may comprise a plurality of individual models including one or more PK models and/or one or more PD models for simulating drug exposure, target engagements and acute attack rate in HAE patients. A virtual patient population representing a plurality of virtual patients may be developed and input into the QSP model for executing a virtual clinical trial. In some embodiments, the QSP model may be used evaluate a response of the contact system and/or an effectiveness of a therapeutic intervention for treating HAE.

Abstract: Provided herein are plasma kallikrein antibodies binding to active plasma kallikrein and methods of using such antibodies in preventing hereditary angioedema attack or reducing the rate of hereditary angioedema attack.

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.
