Abstract: The present invention provides monoclonal antibodies that bind to the Activin A type I receptor (ACVR1) protein, and methods of use thereof. In various embodiments of the invention, the antibodies are fully human antibodies that bind to ACVR1. In some embodiments, the antibodies of the invention are useful for inhibiting ACVR1-mediated bone morphogenetic protein (BMP) signal transduction, thus providing a means of treating or preventing a disease, disorder or condition associated with ACVR1.

Abstract: Provided herein are monoclonal antibodies that bind to the transmembrane serine protease 6 (TMPRSS6) protein, and methods of use thereof. In various embodiments of the disclosure, the antibodies are fully human antibodies that bind to TMPRSS6. In some embodiments, the antibodies disclosed herein are useful in a method for treating or preventing a disease, disorder or condition associated with TMPRSS6 in humans.

Abstract: A genetically modified rodent is provided that comprises a modified Acvr1 gene that comprises a conditional altered exon 7 encoding R258G in antisense orientation, flanked by site-specific recombinase recognition sites, wherein the altered exon is inverted to sense orientation upon action of a recombinase, resulting in ectopic bone formation.

Abstract: The present invention provides antibodies that bind to BMP6, and methods of use. According to certain embodiments of the invention, the antibodies are fully human antibodies that bind to BMP6. The antibodies of the invention are useful for inhibiting binding of BMP6 to the hemojuvelin receptor, thereby down-regulating transcription and expression of hepcidin, thus providing a means of preventing or treating an iron-deficiency anemia or an iron-deficiency related disorder. In some embodiments, the antibodies of the present invention are used in treating at least one symptom or complication of an iron-deficiency anemia or an iron-deficiency related disorder.

Abstract: Methods for treating Fibrodysplasia Ossificans Progressiva (FOP) are provided. Such methods involve administering to a subject having FOP an effective regime of an activin receptor type 2A (ACVR2A) and/or an activin receptor type 2B (ACVR2B) antagonist or an activin receptor type 1 (ACVR1) antagonist. Antagonists include fusion proteins of one or more extracellular domains (ECDs) of ACVR2A, ACVR2B and/or ACVR1 and the Fc domain of an immunoglobulin heavy chain, and antibodies against ACVR2A, ACVR2B, ACVR1 or Activin A.
