Keros Therapeutics Presents Results from a Preclinical Study of RKER-012 in Pulmonary Arterial Hypertension-Associated Bone Loss at the American Society for Bone and Mineral Research 2021 Annual Meeting
Keros Therapeutics, Inc. (Nasdaq: KROS), presented preclinical results of KER-012 at the ASBMR 2021 Annual Meeting, showcasing its efficacy in preventing bone loss in a rodent pulmonary arterial hypertension (PAH) model. RKER-012 demonstrated significant improvements in bone metrics compared to untreated controls, suggesting its potential for treating secondary osteoporosis related to PAH. KER-012 is designed to promote bone growth by inhibiting transforming growth factor-Beta ligands. The company emphasizes KER-012's therapeutic promise for bone loss disorders.
- RKER-012 showed ability to prevent bone loss in rodent PAH model, indicating substantial efficacy.
- Significant improvements in bone volume and structure metrics compared to vehicle-treated controls.
- KER-012 has potential therapeutic applications for treating osteoporosis related to PAH.
- None.
LEXINGTON, Mass., Oct. 04, 2021 (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 and musculoskeletal disorders with high unmet medical need, today announced that it presented results from a preclinical study of KER-012 at the American Society for Bone and Mineral Research (ASBMR) 2021 Annual Meeting held October 1 through 4, 2021.
RKER-012 prevented loss of bone volume, bone volume fraction and trabecular number, and reduced trabecular separation in a rodent PAH model.
- RKER-012, a Novel Activin Receptor Type II Ligand Trap, Protected Rats from Pulmonary Arterial Hypertension-Associated Bone Loss in a SUGEN/Hypoxia Model
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 of pulmonary arterial hypertension (“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 or 20 mg/kg RKER-012 twice weekly for four weeks. Rats maintained under normal oxygen conditions (“normoxic controls”) received only vehicle. Relative to normoxic controls, vehicle-treated SH rats had reduced bone volume (-
“We are excited to announce additional preclinical data from our KER-012 program, which we presented at the ASBMR 2021 Annual Meeting. The results of this study suggest that RKER-012 prevented bone loss in this PAH model, which we believe supports that KER-012 has the potential to treat bone loss resulting from secondary osteoporosis, such as in PAH,” said Jasbir S. Seehra, Ph.D., President and Chief Executive Officer of Keros.
About KER-012
KER-012 is designed to bind to and inhibit the transforming growth factor-Beta ligands that suppress bone growth, including activin A and activin B, in order to promote bone growth to potentially treat diseases such as osteogenesis imperfecta and osteoporosis. 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 due to inactivating mutations in the BMP receptors. KER-012 is being developed for the treatment of disorders associated with bone loss, such as osteogenesis imperfecta and osteoporosis, and for the treatment of PAH.
