Keros Therapeutics Reports Recent First Quarter 2026 Financial Results

LEXINGTON, Mass., May 14, 2026 (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 March 31, 2026.

“Continuing to progress our pipeline remains our top priority, setting the stage for future catalysts and growth opportunities,” said Jasbir S. Seehra, Ph.D., President and Chief Executive Officer. “In addition, we are excited that our partner, Takeda Pharmaceuticals U.S.A., Inc. (“Takeda”), plans to advance elritercept into a Phase 3 clinical trial to evaluate elritercept as a treatment of anemia in myelofibrosis, broadening the indication opportunity beyond myelodysplastic syndromes.”

First Quarter 2026 Financial Results

Keros reported a net loss of $23.7 million in the first quarter of 2026 as compared to a net income of $148.5 million in the first quarter of 2025. The decrease of $172.2 million was largely due to revenue recognized in 2025 related to Keros' license agreement with Takeda and decreased research and development efforts.

Research and development expenses were $16.1 million for the first quarter of 2026 as compared to $48.7 million for the same period in 2025. The decrease of $32.6 million was primarily due to the transition of elritercept-related research and development expenses to Takeda and the corporate restructuring that was completed in 2025.

General and administrative expenses were $10.1 million for the first quarter of 2026 as compared to $10.5 million for the same period in 2025. The decrease of $0.4 million was primarily due to a decrease in compensation costs in connection with the 2025 corporate restructuring.

Keros’ cash and cash equivalents as of March 31, 2026 was $281.5 million compared to $287.4 million as of December 31, 2025. Based on current operating assumptions, Keros expects that its cash and cash equivalents as of March 31, 2026 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 skeletal muscle, bone, adipose, heart tissue and blood. 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, rinvatercept, is being developed for the treatment of Duchenne muscular dystrophy and for the treatment of amyotrophic lateral sclerosis. 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.
