Abstract:
This disclosure relates to antagonistic dual receptor antigen-binding proteins, e.g. antibodies and methods of using the dual receptor antibodies for treatment of pathological diseases. The dual receptor antibodies may comprise an antibody to ActRII receptors and may be used to treat pathological condition. The pathological conditions can comprise muscle wasting diseases or any disease that requires stimulation of muscle growth.
Abstract:
The disclosure provides compositions and methods relating to or derived from anti-activin A binding proteins, including antibodies. In particular embodiments, the disclosure provides fully human, humanized, and chimeric anti-activin A antibodies that bind human activin A, activin A-binding fragments and derivatives of such antibodies, and activin A-binding polypeptides comprising such fragments. Other embodiments provide nucleic acids encoding such antibodies, antibody fragments and derivatives and polypeptides, cells comprising such polynucleotides, methods of making such antibodies, antibody fragments and derivatives and polypeptides, and methods of using such antibodies, antibody fragments and derivatives and polypeptides, including methods of treating or diagnosing subjects having activin A-related disorders or conditions including cachexia related to gonadal cancer, other cancers, rheumatoid arthritis, and other diseases.
