Release Details

LEXINGTON, Mass., March 03, 2023 (GLOBE NEWSWIRE) -- Keros Therapeutics, Inc. (“Keros” or the “Company”) (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 provided a business update and reported financial results for the fourth quarter and full year ended December 31, 2022.

“2022 was another momentous year for Keros - consistent execution throughout last year has positioned Keros to deliver on several key upcoming milestones in 2023,” said Jasbir S. Seehra, Ph.D., President and Chief Executive Officer. “We are excited by the momentum and engagement around our two ongoing Phase 2 clinical trials of KER-050, one in patients with myelodysplastic syndromes ("MDS") and one in patients with myelofibrosis, as we believe KER-050 has significant potential to address unmet patient need in a differentiated way. Additionally, we will continue to leverage our understanding of the transforming growth factor-beta family of proteins to research our library of proprietary molecules, in order to expand our development programs related to hematological, pulmonary and cardiovascular disorders.”

Recent Corporate Highlights:

• Cash position strengthened: The Company has utilized its existing at the market offering ("ATM") to sell additional shares of common stock, which strengthened its cash position. The Company expects that its cash and cash equivalents as of December 31, 2022, together with the net proceeds from the ATM through February 28, 2023, will enable the Company to fund its operating expenses and capital expenditure requirements into the third quarter of 2025.

2022 Financial Results

Keros reported a net loss of $29.7 million for the fourth quarter and $104.7 million for the year ended December 31, 2022, as compared to a net loss of $6.9 million for the fourth quarter and $58.7 million for the year ended December 31, 2021. The increase in net loss for the fourth quarter and the increase in net loss for the year was largely due to increased research and development efforts, including the progression of the Company's two Phase 2 clinical trials in KER-050, one in patients with MDS and one in patients with myelofibrosis, plus an upfront payment from the Company's license agreement with Hansoh (Shanghai) Healthtech Company Limited (“Hansoh”) in the fourth quarter of 2021.

Keros did not generate any revenue for the year ended December 31, 2022. The revenue for the year ended December 31, 2021 was $20.1 million, which was primarily related to the license agreement Keros entered into with Hansoh.

Research and development expenses were $24.9 million for the fourth quarter and $87.3 million for the year ended December 31, 2022, as compared to $18.8 million for the fourth quarter and $55.1 million for the year ended December 31, 2021. The increase in research and development expenses for the fourth quarter and the year was driven by the continued advancement of the Company's pipeline, notably the progression of its two Phase 2 clinical trials of KER-050, as well as an increase in the infrastructure to support operations and expansion of its programs.

General and administrative expenses were $7.1 million for the fourth quarter and $27.5 million for the year ended December 31, 2022, as compared to $6.0 million and $21.3 million for the year ended December 31, 2021. The increase was primarily due to an increase in personnel expenses, which includes additional stock-based compensation costs to support the Company's organizational growth and achievement of its corporate goals, an increase in facilities, supplies and other office expenses due to growth of the Company's organization, and an increase in professional fees and director and officer insurance premiums.

Keros’ cash and cash equivalents as of December 31, 2022 was $279.0 million compared to $230.0 million as of December 31, 2021. Keros expects that the cash and cash equivalents it had on hand at December 31, 2022, together with the net proceeds from the ATM through February 28, 2023, will fund its operating expenses and capital expenditure requirements into the third quarter of 2025.
