The present invention relates to methods of treating ovarian cancer in a subject by administering to the subject by evaluating the subject's expression levels of specific biomarkers or angiogenic an anti-activin-A compound, such as an anti-activin-A antibody or an activin-A-binding receptor. In some embodiments, at least two compounds are administered to the subject, where the first compound is an anti-activin A compound, and the second compound is a chemotherapeutic compound, for example capecitabine. The invention further relates to methods of identifying subjects for treatment factors.

Administration of an anti-activin-a compound to a subject

The present disclosure describes novel hybrid soluble ActRIIB-ECD polypeptides which fully retain binding affinity for myostatin and activin A but demonstrate significantly reduced binding to BMPs, especially BMP-9. The novel compositions described herein can be used to prepare novel hybrid ActRIIB ligand trap proteins, which can be used for modulating the growth of muscle, bone, cartilage, fat, fibroblast, blood and neuronal tissue to counteract muscle wasting, bone loss, anemia, inflammation and fibrosis in a therapeutically meaningful manner. Because these novel next-generation myostatin/activin inhibitors are safer and more effective molecules than the currently available myostatin inhibitors, they are useful in a wide variety of clinical indications.

Hybrid ActRIIB ligand trap proteins for treating muscle wasting diseases

Administration of an anti-activin-A compound to a subject

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.

Anti-activin A antibodies and uses thereof

This disclosure related 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.

Dual receptor antagonistic antigen-binding proteins and uses thereof

The present invention provides variant activin IIB soluble receptor polypeptides and proteins capable of binding and inhibiting the activities of activin A, myostatin, or GDF-11. The present invention also provides polynucleotides, vectors and host cells capable of producing the variant polypeptides and proteins. Compositions and methods for treating muscle-wasting and other diseases and disorders are also provided.

Variant activin receptor

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.

Variant activin receptor polypeptides, alone or in combination with chemotherapy, and uses thereof
