Keros Therapeutics Reports Second Quarter 2025 Financial Results

LEXINGTON, Mass., Aug. 06, 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 June 30, 2025.

“The second quarter marked an important point for Keros, as Keros’ Board of Directors (the “Board”) completed its comprehensive strategic review,” said Jasbir S. Seehra, Ph.D., Chair and Chief Executive Officer. “Following the review, our focus remains on creating long-term value through advancing the development of our pipeline of novel therapeutics, including our lead asset, KER-065, which the team is progressing towards initiation of a Phase 2 clinical trial in patients with Duchenne muscular dystrophy in the first quarter of 2026.”

Second Quarter 2025 Financial Results

Keros reported a net loss of $30.7 million in the second quarter of 2025 as compared to a net loss of $45.3 million in the second quarter of 2024. The decrease of $14.6 million was largely due to revenue recognized related to Keros’ license agreement with Takeda Pharmaceuticals U.S.A., Inc., partially offset by increased research and development efforts as well as additional investments to support the achievement of Keros’ clinical and corporate goals.

Research and development expenses were $43.5 million for the second quarter of 2025 as compared to $40.5 million for the same period in 2024. The increase of $3.0 million was primarily due to additional research and development efforts.

General and administrative expenses were $14.5 million for the second quarter of 2025 as compared to $10.0 million for the same period in 2024. The increase of $4.5 million was primarily due to an increase in other external expenses.

Keros’ cash and cash equivalents as of June 30, 2025 was $690.2 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 June 30, 2025, less $375.0 million of excess capital that the Board 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.
