Keros Therapeutics Reports Recent Business Highlights and Fourth Quarter and Full Year 2020 Financial Results

LEXINGTON, Mass., March 25, 2021 (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 and musculoskeletal 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, 2020.

“2020 was a transformative year for Keros, as we continued to make important preclinical and clinical progress across our pipeline and brought the company public,” said Jasbir S. Seehra, Ph.D., President and Chief Executive Officer. “While our open-label Phase 2 clinical trial of KER-050 in patients with myelodysplastic syndromes is ongoing, we are also working to initiate three more Phase 2 clinical trials this year: a KER-050 trial in patients with myelofibrosis and two KER-047 trials, one in patients with iron deficiency anemia and one in patients with iron-refractory iron deficiency anemia. Our ability to progress multiple product candidates over the last year reflects the dedication of our team and the potential reach of our discovery approach, particularly given the many challenges resulting from the ongoing COVID-19 pandemic.”

Recent Corporate Highlights:

  • Completed public offering: In November 2020, Keros completed its public offering of 2,990,000 shares of common stock, which included the exercise in full by the underwriters of their option to purchase up to 390,000 additional shares, at a public offering price of $50.00 per share, for aggregate gross proceeds to Keros of $149.5 million. Keros received approximately $140.1 million in net proceeds after deducting underwriting discounts and commissions and offering costs.
  • Strengthened leadership with board appointment: In December 2020, Keros appointed Mary Ann Gray, Ph.D., to its board of directors. Concurrent with Dr. Gray joining Keros’ Board of Directors, Alon Lazarus stepped down as a director of the Company.

Recent Program Highlights:

  • KER-050 for the treatment of ineffective hematopoiesis to address cytopenias:
    • Keros has initiated dosing of the first two cohorts (0.75 mg/kg and 1.5 mg/kg) of Part 1 of its Phase 2 clinical trial evaluating KER-050 in patients with myelodysplastic syndromes. The Company expects to report initial data from Part 1 of this trial in mid-2021.
    • Presented preclinical data at the virtual European School of Haematology (“ESH”) 2nd Translational Research E-Conference in March 2021, demonstrating that a research form of KER-050 induced red blood cell production by promoting multiple stages of erythroid differentiation.
  • KER-047 for the treatment of anemia resulting from iron imbalance and for the treatment of fibrodysplasia ossificans progressiva:
    • Presented preclinical data on an ALK2 inhibitor closely related to KER-047 at the March 2021 ESH E-Conference, demonstrating targeted ALK2 inhibition as a potential therapeutic approach to reducing hepcidin and elevating serum iron.
    • Keros expects to initiate two Phase 2 clinical trials of KER-047, one in patients with iron deficiency anemia and one in patients with iron-refractory iron deficiency anemia, in the second half of 2021 and to report initial data from both trials in 2022.

Selected Anticipated 2021 Corporate Milestones:

  • Report initial data from Part 1 of the Phase 2 clinical trial of KER-050 in patients with myelodysplastic syndromes in mid-2021
  • Initiate a Phase 2 clinical trial of KER-050 in patients with myelofibrosis in mid-2021
  • Initiate two Phase 2 clinical trials of KER-047, one in patients with iron deficiency anemia and one in patients with iron-refractory iron deficiency anemia, in the second half of 2021
  • Initiate a Phase 1 clinical trial of KER-012 in the second half of 2021

2020 Financial Results

Keros reported a net loss of $10.7 million for the fourth quarter and $45.4 million for the year ended December 31, 2020, as compared to a net loss of $2.8 million for the fourth quarter and $12.3 million for the year ended December 31, 2019. The increase in net loss for the fourth quarter and the year was largely due to increased research and development efforts as well as the infrastructure to support operations as a publicly traded company.

Research and development expenses were $9.7 million for the fourth quarter and $33.9 million for the year ended December 31, 2020 as compared to $4.2 million for the fourth quarter and $17.4 million for the year ended December 31, 2019. The increase in research and development expense for the fourth quarter and the year was primarily due to additional preclinical, clinical and manufacturing activities, as well as an increase related to personnel expenses, including additional share-based compensation cost, driven primarily by increased headcount.

General and administrative expenses were $3.6 million for the fourth quarter and $12.8 million for the year ended December 31, 2020 as compared to $1.1 million and $3.2 million for the year ended December 31, 2019. The increase was primarily due to an increase in personnel expenses to support Keros' organizational growth, additional share-based compensation costs and an increase in professional fees to support Keros' transition to a public company.

Keros’ cash and cash equivalents as of December 31, 2020 was $265.9 million compared to $7.0 million as of December 31, 2019. Keros substantially extended its cash runway, largely by raising $55.8 million in net proceeds from its March 2020 Series C preferred stock offering, $100.1 million in net proceeds from its April 2020 initial public offering and $140.1 million in net proceeds from its November 2020 public offering. Keros expects that the cash and cash equivalents it had on hand at December 31, 2020 will fund its operating expenses and capital expenditure requirements into the fourth quarter of 2023.
