  • Publication number: 20240117334
    Abstract: Provided herein are engineered proteases of the S1A family that are specific for, and capable of, cleaving Factor B. Also provided herein are methods of making and using such engineered proteases. The engineered proteases provided herein may be useful for treating a disease or condition associated with dysregulation of the complement system by reducing complement activation through cleavage and inactivation of Factor B.

  • Publication number: 20240018502
    Abstract: Provided are MTSP-1 polypeptides modified to have altered activity and/or specificity so that they cleave a complement protein, such as complement protein C3, to inhibit its activity and thereby inhibit complement activation. The modified MTSP-1 polypeptides that inhibit complement activation can be used for treatment of diseases and conditions in which complement activation plays a role. Such diseases and conditions include inflammatory diseases and diseases with an inflammatory component. Exemplary of these disorders are ischemic and reperfusion disorders, including myocardial infarction and stroke, sepsis, autoimmune diseases, ophthalmic disorders, such as diabetic retinopathies and macular degeneration, including age-related macular degeneration (AMD), and transplanted organ rejection, such as renal delayed graft function (DGF).

  • Publication number: 20230242895
    Abstract: Provided are nucleic acid molecules, including vectors and plasmids, encoding modified u-PA polypeptides and fusion proteins containing the modified u-PA polypeptides. The u-PA polypeptides are modified to have altered activity and/or specificity so that they cleave a complement protein, such as complement protein C3, to thereby inhibit complement activation. The nucleic acids and encoded modified u-PA polypeptides and fusion proteins that inhibit complement activation can be used for treatment of diseases and conditions that are mediated by complement activation, or in which complement activation plays a role. These disorders include ischemic and reperfusion disorders, including myocardial infarction and stroke, sepsis, autoimmune diseases, diabetic retinopathies, age-related macular degeneration, transplanted organ rejection, inflammatory diseases and diseases with an inflammatory component.
