Patent
Acceleron Pharma Inc. | Date: 2016-08-04

In part, the present disclosure relates methods for treating, preventing, or reducing the severity of a myeloproliferative disorder (e.g., polycythemia vera, essential thrombocythemia, and myelofibrosis) or one or more complications of a myeloproliferative disorder. The present disclosure further relates methods for treating, preventing, or reducing the severity of a Janus kinase-associated disorder or one or more complications of a Janus kinase-associated disorder. In certain aspects the disclosure provides TRII antagonists for treating, preventing, or reducing the severity of a myeloproliferative disorder (e.g., polycythemia vera, essential thrombocythemia, and myelofibrosis) or a Janus kinase-associated disorder or one or more complications of a myeloproliferative disorder or a Janus kinase-associated disorder.

In certain aspects, the present invention provides compositions and methods for modulating (promoting or inhibiting) growth of a tissue, such as bone, cartilage, muscle, fat, and/or neuronal tissue. The present invention also provides methods of screening compounds that modulate activity of an ActRIIB protein and/or an ActRIIB ligand. The compositions and methods provided herein are useful in treating diseases associated with abnormal activity of an ActRIIB protein and/or an ActRIIB ligand.


Compositions for increasing red blood cell levels or treatment of anemia comprising erythropoietin receptor activators and a variant Activin RIIB (ActRIIB) polypeptide having a leucine residue replaced by a acidic amino acid residue, where the variant ActRIIB polypeptide has a reduced affinity for activin B and may be called a GDF trap. Methods for the use of these compositions.


Some aspects of this disclosure provide methods and compositions for the treatment of cancer, for example, head and neck cancer, in a subject using ALK1 inhibitors, e.g., ALK1-ECD polypeptides, ALK1-Fc fusion proteins, or ALK1-inhibitory antibodies. In some embodiments, methods and compositions are provided for treating certain cancers with ALK1 inhibitors in combination with a chemotherapeutic platinum agent. In some embodiments, methods are provided for identifying whether a cancer in a subject will react to treatment with an ALK1 antagonist, either alone or in combination with a chemotherapeutic platinum agent, for example, based on a determination that the cancer or the subject is positive for human papilloma virus.

In certain aspects, the present disclosure relates to the insight that a polypeptide comprising a ligand-binding portion of the extracellular domain of activin-like kinase I (ALK1) polypeptide may be used to inhibit angiogenesis in vivo, particularly in mammals suffering angiogenesis-related disorders. In certain aspects, the disclosure demonstrates that antagonists of BMP9 and/or BMP10, ligands for ALK1, may also be used to inhibit angiogenesis in vivo.

In certain aspects, the present invention provides compositions and methods for increasing red blood cell and/or hemoglobin levels in vertebrates, including rodents and primates, and particularly in humans.


In certain aspects, the present invention provides compositions and methods for treating or preventing breast cancer in humans.

In certain aspects, the present invention provides compositions and methods for promoting bone growth and increasing bone density.


In certain aspects, the present disclosure provides compositions and methods for increasing red blood cell and/or hemoglobin levels in a subject in need thereof comprising administering an effective amount of an agent/s that inhibits activin B and/or GDF11. Subjects in need include, for example, subject having an anemia and subjects have an ineffective erythropoiesis disorder.


The present invention relates to follistatin-Fc fusion proteins that have effects in the tissue of administration (such as an injected muscle), rather than systemic effects. The Fc domain results in dimerization of the follistatin-Fc fusion protein, and provides enhanced tissue retention. The description includes fusion proteins comprising a human follistatin polypeptide consisting of FST288, FST291 (a non-natural truncated follistatin) or FST315; and a human IgGl or IgG2 Fc domain.
