Abstract: 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.

Abstract: This invention disclosure provides novel bifunctional antagonistic polypeptides comprising at least one TNF-? binding domain and at least one Activin-binding domain, which are highly capable of sequestering TNF-? and Activin or Activin-related ligand in parallel. Also provided are pharmaceutical compositions of such bifunctional polypeptide antagonists and their uses to treat various complex disease conditions, whose pathogenesis involve the activation of both TNF-?-mediated NF-?B signaling pathway and Activin-mediated Smad2/3 signaling pathway.

Abstract: This invention disclosure provides novel bifunctional molecules comprising at least one RANKL binding molecule and at least one Activin or TGF-? binding molecule, which are capable of sequestering RANKL and Activin or TGF-? in parallel. Also provided are pharmaceutical compositions of such bifunctional antagonist molecules and their therapeutic uses to treat various bone disorders whose pathogenesis involves the activation of both RANKL-NF?B and Activin/TGF?-Smad2/3 signaling pathways, such as bone metastasis, bone loss in cancer, bone fragility in neuromuscular diseases, osteogenesis imperfecta, fracture, osteopenia and osteoporosis.
