(MENAFN- GlobeNewsWire - Nasdaq) LEXINGTON, Mass., Nov. 05, 2025 (GLOBE NEWSWIRE) -- Keros Therapeutics, Inc. (“Keros” or the“Company”) (Nasdaq: KROS), a clinical-stage biopharmaceutical company focused on developing and commercializing novel therapeutics to treat a wide range of patients with disorders that are linked to dysfunctional signaling of the transforming growth factor-beta (“TGF-ß”) family of proteins, today reported financial results for the quarter ended September 30, 2025.

“We are excited that our partner Takeda plans to advance elritercept into a Phase 3 clinical trial to evaluate elritercept in the first-line setting in myelodysplastic syndromes,” said Jasbir S. Seehra, Ph.D., President and Chief Executive Officer.“We are pleased with the continued progress of both our partner and our internal pipeline, as we advance toward initiating a Phase 2 clinical trial of KER-065 in patients with Duchenne muscular dystrophy.”

Third Quarter 2025 Financial Results

Keros reported a net loss of $7.3 million in the third quarter of 2025 as compared to a net loss of $53.0 million in the third quarter of 2024. The decrease of $45.7 million was largely due to revenue recognized related to Keros' license agreement with Takeda Pharmaceuticals U.S.A., Inc. (“Takeda”), partially offset by research and development efforts as well as additional investments to support the achievement of Keros' clinical and corporate goals.

Research and development expenses were $19.5 million for the third quarter of 2025 as compared to $49.2 million for the same period in 2024. The decrease of $29.7 million was primarily due to the transition of elritercept-related research and development expenses to Takeda.

General and administrative expenses were $10.1 million for the third quarter of 2025 as compared to $9.8 million for the same period in 2024. The increase of $0.3 million was primarily due to an increase in other external expenses partially offset by a decrease in compensation costs, including stock-based compensation costs, in connection with a reduction in headcount.

Keros' cash and cash equivalents as of September 30, 2025 was $693.5 million compared to $559.9 million as of December 31, 2024. Based on current operating assumptions, Keros expects that its cash and cash equivalents as of September 30, 2025, less $375.0 million of excess capital that the Company's Board of Directors has determined to return to stockholders, will enable Keros to fund its operating expenses and capital expenditure requirements into the first half of 2028.

About Keros Therapeutics, Inc.

Keros is a clinical-stage biopharmaceutical company focused on developing and commercializing novel therapeutics to treat a wide range of patients with disorders that are linked to dysfunctional signaling of the TGF-ß family of proteins. Keros is a leader in understanding the role of the TGF-ß family of proteins, which are master regulators of the growth, repair and maintenance of a number of tissues, including blood, bone, skeletal muscle, adipose and heart tissue. By leveraging this understanding, Keros has discovered and is developing protein therapeutics that have the potential to provide meaningful and potentially disease-modifying benefit to patients. Keros' lead product candidate, KER-065, is being developed for the treatment of neuromuscular diseases, with an initial focus on Duchenne muscular dystrophy. Keros' most advanced product candidate, elritercept, is being developed for the treatment of cytopenias, including anemia and thrombocytopenia, in patients with myelodysplastic syndrome and in patients with myelofibrosis.
