[{"type":"text","content":"LEXINGTON, Mass., June 13, 2022 (GLOBE NEWSWIRE) -- Keros Therapeutics, Inc. (“Keros” or the “Company”) (Nasdaq: KROS), a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of novel treatments for patients suffering from hematological and musculoskeletal disorders with high unmet medical need, today announced results from a preclinical study of RKER-012 on cardiac and pulmonary pathology in an established rodent model of pulmonary arterial hypertension (“PAH”), which were presented at the Pulmonary Hypertension Association International Conference and Scientific Sessions held on June 10 through 12, 2022. RKER-012 reduced cardiac and pulmonary pathology in a rodent PAH model. RKER-012, a Novel Activin Receptor Type IIB (“ActRIIB”) Ligand Trap, Reduced Cardiac and Pulmonary Pathology in a Sugen/Hypoxia Model of PAH Keros combined administration of SUGEN5416, a tyrosine kinase inhibitor of vascular endothelial growth factor receptors 1/2, with exposure to chronic hypoxia to recapitulate the biology in PAH. A research form of KER-012 (“RKER-012”) was tested in this SUGEN/hypoxia (“SH”) rat model of PAH. Adult male rats were subjected to SH and received either vehicle, 10 mg/kg of activin receptor type IIA-Fc (“ActRIIA-Fc”) or 10 mg/kg RKER-012 twice weekly for three weeks. Rats maintained under normal oxygen conditions (“normoxic controls”) received only vehicle. Consistent with the development of cardiac and pulmonary impairment, vehicle-treated SH rats exhibited increases in Fulton index, which measures enlargement of the right ventricle (p0.05) relative to the vehicle-treated SH rats. However, relative to the vehicle-treated SH rats, treatment of the SH rats with RKER-012 significantly attenuated increased Fulton index (p","length":2086,"tagName":"div"}]
