METHODS FOR TREATING CONDITIONS ASSOCIATED WITH MASP-2 DEPENDENT COMPLEMENT ACTIVATION

摘要

In one aspect, the invention provides methods of inhibiting the effects of MASP-2-dependent complement activation in a living subject. The methods comprise the step of administering, to a subject in need thereof, an amount of a MASP-2 inhibitory agent effective to inhibit MASP-2-dependent complement activation. In some embodiments, the MASP-2 inhibitory agent inhibits cellular injury associated with MASP-2-mediated alternative complement pathway activation, while leaving the classical (C1q-dependent) pathway component of the immune system intact. In another aspect, the invention provides compositions for inhibiting the effects of lectin-dependent complement activation, comprising a therapeutically effective amount of a MASP-2 inhibitory agent and a pharmaceutically acceptable carrier.

主权项

1. A method of inhibiting adverse effects of transplantation in a subject that has undergone, is undergoing, or will undergo an organ or tissue transplant procedure comprising administering to the subject, or pretreating the organ or tissue to be transplanted with, a composition comprising a monoclonal MASP-2 inhibitory antibody, or antigen-binding fragment thereof, that specifically binds to a portion of SEQ ID NO:6 and inhibits MASP 2 dependent complement activation.
