LEXINGTON, Mass., Nov. 07, 2022 (GLOBE NEWSWIRE) -- Keros Therapeutics, Inc. (“Keros”) (Nasdaq: KROS), a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of novel treatments for patients suffering from hematological, pulmonary and cardiovascular disorders with high unmet medical need, today announced results from a preclinical study of a research form of KER-012 ("RKER-012") on cardiac and pulmonary pathology in an established rat model of pulmonary arterial hypertension (“PAH”), which were presented at the American Heart Association 2022 Scientific Sessions on Monday, November 7, 2022.
“We are pleased to have reported encouraging preclinical data from our KER-012 program showing that treatment with RKER-012 led to improvement in cardiac and pulmonary function in a rat model of PAH. This cardiopulmonary improvement was associated with reductions in inflammatory and fibrotic markers, including TGFβ-1, which is the most potent driver of fibrosis in the transforming growth factor-beta (“TGF-β”) family of ligands,” said Jasbir S. Seehra, Ph.D., President and Chief Executive Officer of Keros. “We believe these data further validate that KER-012 has the potential to treat not only PAH but also other inflammatory and fibrotic diseases of the heart and the lungs.”
RKER-012 improved cardiopulmonary function in a rat PAH model.
Keros combined administration of SUGEN5416, a tyrosine kinase inhibitor of vascular endothelial growth factor receptors 1/2, with exposure to chronic hypoxia to induce PAH in adult rats. RKER-012 was tested in this SUGEN/hypoxia (“SH”) rat PAH model. Adult rats subjected to SH received either vehicle or 10 mg/kg of RKER-012 twice weekly for three weeks. Rats maintained under normal oxygen conditions (“normoxic controls”) received only vehicle.
About KER-012
KER-012 is designed to bind to and inhibit the signaling of TGF-β ligands that stimulate smooth muscle hypertrophy and fibrosis, including activin A, activin B and myostatin (GDF8). Keros believes that KER-012 has the potential to increase the signaling of bone morphogenic protein (“BMP”) pathways through this inhibition of activin A and activin B signaling, and consequently treat diseases such as PAH that are associated with reduced BMP signaling. KER-012 is being developed for the treatment of PAH and for the treatment of cardiovascular disorders associated with cardiac hypertrophy.
About Keros Therapeutics, Inc.
Keros is a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of novel treatments for patients suffering from hematological, pulmonary and cardiovascular disorders with high unmet medical need. Keros is a leader in understanding the role of the TGF-β family of proteins, which are master regulators of red blood cell and platelet production as well as of the growth, repair and maintenance of a number of tissues, including blood vessels and heart tissue. Keros’ lead protein therapeutic product candidate, KER-050, is being developed for the treatment of low blood cell counts, or cytopenias, including anemia and thrombocytopenia, in patients with MDS and in patients with myelofibrosis. Keros’ lead small molecule product candidate, KER-047, is being developed for the treatment of functional iron deficiency. Keros’ third product candidate, KER-012, is being developed for the treatment of pulmonary arterial hypertension and for the treatment of cardiovascular disorders associated with cardiac hypertrophy.
