Treating diffuse alveolar hemorrhage with masp-2 inhibitory antibody
A recently granted patent (Publication Number: US11896621B2) discloses a method for treating diffuse alveolar hemorrhage associated with hematopoietic stem cell transplant in human subjects. The method involves administering a composition containing a MASP-2 inhibitory antibody or its antigen-binding fragment to inhibit MASP-2-dependent complement activation. The antibody can be a monoclonal antibody specifically binding to human MASP-2, with various forms such as recombinant, chimeric, humanized, or human antibodies being suitable for use.
Furthermore, the method includes identifying subjects at risk for diffuse alveolar hemorrhage before administering the MASP-2 inhibitory antibody systemically. The antibody used in the treatment does not substantially inhibit the classical pathway and effectively inhibits C3b deposition in human serum. The patent also covers cases where the subject has undergone or will undergo a hematopoietic stem cell transplant, emphasizing the importance of this method in managing complications associated with such procedures. The specific amino acid sequences of the antibody variable regions are also disclosed in the claims, providing detailed information on the composition used in the treatment process.
