In some aspects, the disclosure relates to GDF/BMP antagonists and methods of using GDF/BMP antagonists to treat, prevent, or reduce the progression rate and/or severity of pulmonary hypertension (PH), particularly treating, preventing or reducing the progression rate and/or severity of one or more PH-associated complications. The disclosure also provides methods of using a GDF/BMP antagonist to treat, prevent, or reduce the progression rate and/or severity of a variety of conditions including, but not limited to, pulmonary vascular remodeling, pulmonary fibrosis, and right ventricular hypertrophy. The disclosure further provides methods of using a GDF/BMP antagonist to reduce right ventricular systolic pressure in a subject in need thereof.

The present invention provides a recombinant exosome comprising a membrane-bound EGF protein on the surface of the recombinant exosome and provides a use of the recombinant exosome.

In some aspects, the disclosure relates to compositions and methods comprising ActRII polypeptides to treat, prevent, or reduce the progression rate and/or severity of pulmonary arterial hypertension, particularly treating, preventing or reducing the progression rate and/or severity of one or more pulmonary arterial hypertension associated complications.

Provided herein are methods of treating anemia or for enhancing late stage erythropoiesis in a subject comprising administering to the subject an activin type IIB (ActRIIB) ligand trap and an mTOR inhibitor.

Provided herein are methods of treating anemia or for enhancing late stage erythropoiesis in a subject comprising administering to the subject an activin type IIB (ActRIIB) ligand trap and an mTOR inhibitor.

A liquid formulation of a long-acting conjugate of a peptide having activities for a glucagon receptor and a GLP-1 receptor, and a method for preparing the liquid formulation are disclosed. The liquid formulation contains 18 nmol/mL to 940 nmol/mL of the long-acting conjugate, a buffering agent in an amount for maintaining the pH of the liquid formulation in the range of 4.5 to 7.5, and 1% (w/v) to 20% (w/v) of saccharide, and 0.001% (w/v) to 0.2% (w/v) of a nonionic surfactant.

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.

Disclosed herein are compositions and methods for increasing visual acuity in patients in need thereof and for treating vascular disorders of the eye.

In part, the invention provides a new combination comprising (1) a GLP-1R agonist and (2) an ACC inhibitor or a DGAT2 inhibitor, or a KHK inhibitor or FXR agonist. The invention further provides new methods for treating diseases and disorders, for example, fatty liver, nonalcoholic fatty liver disease, nonalcoholic steatohepatitis, nonalcoholic steatohepatitis with liver fibrosis, nonalcoholic steatohepotitis with cirrhosis, and nonalcoholic steatohepatitis with cirrhosis and with hepatocellular carcinoma or with a metabolic-related disease, obesity, and type 2 diabetes, for example, using the new combination described herein.

The invention features polypeptides that include an extracellular ActRlla variant. In some embodiments, a polypeptide of the invention includes an extracellular ActRlla variant fused to an Fc domain monomer or moiety. The invention also features pharmaceutical compositions and methods of using the polypeptides to treat diseases and conditions involving bone damage, e.g., primary osteoporosis, secondary osteoporosis, osteopenia, osteopetrosis, fracture, bone cancer or cancer metastasis-related bone loss, Paget's disease, renal osteodystrophy, treatment-related bone loss, diet-related bone loss, bone loss associated with the treatment of obesity, low gravity-related bone loss, or immobility-related bone loss.
