7 results about "Contact activation" patented technology

Novel binding molecules comprising humanized antibodies, fragments, variants, and derivatives thereof, as well as compositions, methods, and kits comprising the same, are described, wherein the binding molecules specifically bind to FX1 and FX1a. The binding molecules are capable of binding to the factor X1A2 domain and forming immune complexes, thereby disrupting the contact activation molecule complex without affecting the activity or activation of hemostatic factor XI. The binding molecules disclosed herein are suitable for safely inhibiting thrombosis and inflammation without impairing hemostasis. Thus, the binding molecules, compositions, methods, and kits provided herein are intended for treating diseases and conditions, particularly those associated with thrombosis and inflammation. In addition, polynucleotides encoding the binding molecules disclosed herein, vectors comprising the polynucleotides, and host cells for producing the polynucleotides are also provided.

The present invention provides compositions and methods for inhibiting thrombosis in subjects at risk of thrombosis, such as those with a genetic, acquired, or environmental risk of thrombosis. [Solution] The present invention provides RNAi agents, such as double-stranded RNAi agents, that target kallikrein B, plasma (Fletcher factor) 1 (KLKB1) gene, factor XII (Hageman factor (F12) gene, or kininogen 1 (KNG1) gene, as well as methods for inhibiting the expression of the KLKB1 gene, F12 gene, and / or KNG1 gene using such RNAi agents, and methods for treating subjects with hereditary angioedema (HAE) and / or contact activation pathway-related disorders.

To provide methods for identifying a subject having, suspected of having, or being at risk for a disease associated with the contact activation system.SOLUTION: A method for analyzing a sample includes measuring the level of a RNA biomarker set including at least one RNA biomarker disclosed herein.SELECTED DRAWING: None

The present invention relates to RNAi agents, e.g., double stranded RNAi agents, targeting the Kallikrein B, Plasma (Fletcher Factor) 1 (KLKB1) gene, the Factor XII (Hageman Factor (F12) gene, or the Kininogen 1 (KNG1) gene, and methods of using such RNAi agents to inhibit expression of a KLKB1 gene, an F12 gene, and / or a KNG1 gene, and methods of treating subjects having an hereditary angioedema (HAE) and / or a contact activation pathway-associated disorder.

To provide a method and a kit for analyzing a biological sample obtained from a subject having, suspected to have, or at the risk for a disease associated with a contact activation system.SOLUTION: There is provided a method for analyzing a sample including: (i) preparing a biological sample (for example, serum sample or plasma sample) obtained from a subject (human subject) having, suspected to have, or at the risk for a disease associated with a contact activation system; and measuring the level of a set of biomarkers including at least one type of protein selected from a table 1, in which when the set of biomarkers consists of one type of protein, the protein is not C4, plasma prekallikrein, thrombin, a tissue-type plasminogen activator (tPA), and heat shock protein 90.SELECTED DRAWING: Figure 1

This invention provides methods for treating acute respiratory distress syndrome (ARDS), including ARDS associated with respiratory viral infections. [Solution] Administer plasma kallikrein (pKal) inhibitors such as anti-pKal antibodies as inhibitors of the contact activation pathway. Immunomodulators such as IL-6R inhibitors, antiviral agents such as lopinavir, ritonavir, interferon beta, umfenovir, and remdesivir, antimalarial agents such as chloroquine, and / or inhibitors of the contact activation pathway such as C1 inhibitors, pKal inhibitors, and bradykinin receptor antagonists may be administered to the patient as additional therapeutic agents.
