Keros Therapeutics to Present at the 64th American Society of Hematology Annual Meeting and Exposition, Including Presenting Data from its Phase 2 Clinical Trials Evaluating KER-050 and KER-047

LEXINGTON, Mass., Nov. 03, 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 that five abstracts will be presented from the KER-050 and KER-047 hematology programs at the 64^th American Society of Hematology (“ASH”) Annual Meeting and Exposition, to be held in person and virtually from December 10 through 13, 2022. Keros will be presenting additional and initial preliminary results, respectively, from its two Phase 2 clinical trials of KER-050, one in patients with very low-, low-, or intermediate-risk myelodysplastic syndromes (“MDS”) and one in patients with myelofibrosis. In addition, Keros will be presenting preliminary results from its Phase 2 clinical trial of KER-047 in patients with iron-refractory iron deficiency anemia.

“We are excited to have multiple abstracts accepted for presentation at ASH, which provides us with the opportunity to share updates from our preclinical and Phase 2 clinical programs, including biomarker data from our ongoing Phase 2 clinical trial of KER-050 in patients with MDS,” said Jasbir S. Seehra, Ph.D., President and Chief Executive Officer of Keros. “We remain on track to release additional efficacy data from our KER-050 Phase 2 MDS trial by mid-December 2022.”

The following abstracts were posted to the ASH website on November 3, 2022, 9:00 a.m. Eastern time.

About KER-050

Keros’ lead protein therapeutic product candidate, KER-050, is an engineered ligand trap comprised of a modified ligand-binding domain of the transforming growth factor-beta (“TGF-β”) superfamily receptor known as activin receptor type IIA that is fused to the portion of the human antibody known as the Fc domain. 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.

About KER-047

Keros’ lead small molecule product candidate, KER-047, is designed to selectively and potently inhibit activin receptor-like kinase-2, a TGF-β superfamily receptor. KER-047 is being developed for the treatment of functional iron deficiency which is a consequence of elevated ALK2 signaling.
