Compositions, methods and uses of alpha 1-antitrypsin for early intervention in bone marrow transplantation and treatment of graft versus host disease
View Patent ↗Embodiments of the present invention relate to compositions and methods for treatment of subjects in need of or having a bone marrow transplant. Certain embodiments describe compositions and methods for treatment of conditions associated with bone marrow transplantations in a subject, for example, Graft versus Host Disease (GvHD) or bone marrow transplantation rejection. Some embodiments concern early or immediate bone marrow transplantation rejection. Certain embodiments relate to compositions and uses of alpha1-antitrypsin (α1-antitrypsin, AAT) and carboxyterminal peptide derivatives thereof and/or compositions and uses of serine protease inhibitors, immunomodulators or anti-inflammatory agent activity similar to that of AAT.
1. A method for treating acute graft versus host disease (GvHD) in a human subject in need thereof, said method comprising administering to the human subject a composition comprising alpha 1-antitrypsin (AAT) and treating GvHD in the human subject.
2. The method of claim 1 , wherein the composition further comprises one or more anti-inflammatory agents.
3. The method of claim 1 , wherein the AAT is full-length and is part of a fusion polypeptide.
4. The method of claim 3 , wherein the fusion polypeptide comprises the full-length AAT fused to an immunoglobulin constant region.
5. The method of claim 1 , wherein the human subject has undergone allogeneic bone marrow implantation.
