摘要:
This invention disclosure provides novel bifunctional antagonistic polypeptides comprising at least one TNF-α binding domain and at least one Activin-binding domain, which are highly capable of sequestering TNF-α 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-α-mediated NF-κB signaling pathway and Activin-mediated Smad2/3 signaling pathway.
摘要:
The present invention provides binding agents comprising peptides capable of binding myostatin and inhibiting its activity. In one embodiment the binding agent comprises at least one myostatin-binding peptide attached directly or indirectly to at least one vehicle such as a polymer or an Fc domain. The binding agents of the present invention produced increased lean muscle mass when administered to animals and decreased fat to muscle ratios. Therapeutic compositions containing the binding agents of the present invention are useful for treating muscle-wasting disorders and metabolic disorders including diabetes and obesity.

摘要:
This invention disclosure describes novel polypeptide antagonists capable of neutralizing multiple members of TGF-β family in a selective manner. Specifically, the multispecific polypeptide antagonists disclosed herein comprise at least one Activin-binding domain and at least one TGF-β-binding domain and therefore, are capable of neutralizing TGF-β and Activin as well as Activin-related ligands in parallel. Moreover, this invention disclosure also discloses bifunctional multispecific polypeptide antagonists designed to inhibit Activin, TGF-β and T-Cell immune checkpoint (i.e., PD1, PDL1 or CTLA4) in a simultaneous manner. Specifically, the bifunctional multispecific antagonists disclosed herein comprise at least one Activin-binding domain, at least one TGF-β-binding domain and at least one PD1-, PDL1- or CTLA4-binding domain. Also provided are pharmaceutical compositions of such multispecific or bifunctional multispecific polypeptide antagonists and their therapeutic uses for treating certain disease conditions, which involve overexpression of both TGF-β and Activin, such as fibrosis and cancer.
