Exhibit 99.1
Keros Therapeutics Reports Recent Business Highlights and Second Quarter 2022 Financial Results


KER-050 data from ongoing Phase 2 study in patients with lower risk myelodysplastic syndromes demonstrated meaningful responses across both ring sideroblast-positive and non-RS patients; 44% of high transfusion burden patients achieved transfusion independence

KER-012 preliminary Phase 1 data exhibited encouraging treatment profile in healthy volunteers with improvements in biomarkers of bone formation with no clinically meaningful changes in red blood cell parameters

Strengthened cash position and extended cash runway to fund operations into Q3 2024

LEXINGTON, Mass., August 4, 2022 (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 musculoskeletal disorders with high unmet medical need, today provided a business update and reported financial results for the quarter ended June 30, 2022.

“We continued the positive momentum for our pipeline programs into the second quarter of 2022. The clinical data demonstrated the potential of differentiated profiles of KER-050 and KER-012,” said Jasbir S. Seehra, Ph.D., President and Chief Executive Officer. “We shared promising clinical data for KER-050 in patients with MDS demonstrating the potential for transfusion independence in RS+ and non-RS patients and in those patients with high transfusion burden. Additionally, we also presented encouraging initial safety and biomarker data for KER-012 from our Phase 1 study in healthy volunteers. We continue making progress and remain on track to report additional data from both studies later this year.”

Recent Program Highlights

•KER-050 for the treatment of ineffective hematopoiesis to address cytopenias associated with myelodysplastic syndromes (MDS) and myelofibrosis (MF)
◦In June 2022, Keros presented data from an ongoing, open-label, two-part Phase 2 clinical trial evaluating KER-050 for the treatment of anemia in patients with very low, low, or intermediate-risk (lower risk) MDS patients at the Annual Congress of the European Hematology Association.
◦As of the data cutoff date (April 3, 2022), 51.9 % of evaluable patients (n=27) achieved overall erythroid response.
◦Importantly, in patients with high transfusion burden (HTB), the overall erythroid response rate (hematologic improvement-erythroid (HI-E) or transfusion independence (TI)) was 68.8 % while 43.8% achieved TI. A 52.9% mean maximum increase in soluble transferrin receptor, a marker of erythropoiesis, was observed with KER-050 treatment. Additionally, a 29.1% mean maximum reduction in serum ferritin, a marker of iron overload was observed with KER-050 treatment.
◦HTB patients achieving HI-E or TI also exhibited a sustained increase in platelets further illustrating the potential that KER-050 has to treat both anemia and thrombocytopenia in MDS patients.
◦KER-050 was generally well-tolerated at all doses evaluated in Part 1, and no drug-related serious adverse events (SAE) or dose-limiting toxicities (DLT) were observed.
◦Following recommendation of the Safety Review Committee, dosing for Part 2 of the KER-050 Phase 2 MDS trial was initiated. The Company expects to report additional data from the trial by end of 2022.
◦KER-050 is also being evaluated in an ongoing Phase 2 trial for treating MF-associated cytopenias and the Company remains on track to report initial data by the end of 2022.



•KER-012 for the treatment of pulmonary arterial hypertension (PAH) and disorders associated with bone loss
◦In May 2022, Keros announced preliminary topline data from the Phase 1 clinical study of KER-012 in healthy postmenopausal women. This is an ongoing randomized, double-blind, placebo controlled, two-part dose-escalation study to evaluate the safety, tolerability, pharmacokinetic, and pharmacodynamic effects of treatment with KER-012.
◦In the single ascending dose portion of the study, dosing with KER-012 was generally observed to be well tolerated at all doses up to 5 mg/kg with no SAEs noted. Majority of adverse events were mild (Grade 1 category).
◦Maximal target engagement was seen with the 5 mg/kg dose (39.6% mean reduction in follicle-stimulating hormone levels) on day 22 post-treatment.
◦Robust changes in bone formation markers were also observed, with up to 36.4% mean maximal increase in bone specific alkaline phosphatase (BSAP) elicited upon a single treatment of KER-012. These increases are consistent with restoration of bone morphogenic protein (BMP) signaling. Keros believes this supports the development of KER-012 as a potential treatment for patients with PAH, which is associated with reduced BMP signaling.
◦Further, no clinically meaningful changes in hemoglobin, red blood cells or reticulocytes were observed at any dose level.
◦An ongoing multiple ascending dose (MAD) portion of the Phase 1 KER-012 study is expected to report additional data in the second half of 2022. The Company anticipates announcing the design of a Phase 2 trial in PAH in early 2023.

•KER-047 for the treatment of anemias resulting from iron imbalance
◦In June 2022, Keros commenced an open label, two-part, MAD Phase 2 clinical trial to evaluate single (Part 1) and multiple ascending doses (Part 2) of KER-047 in patients with iron-refractory iron deficiency anemia. The Company anticipates reporting initial data from this trial by the end of 2022.
◦The Company expects to initiate a Phase 2 study in iron-deficiency anemia in the second half of 2022 and anticipates reporting initial data in first half of 2023.

•Cash position strengthened
◦The Company has utilized its "at-the-market" shelf registration statement to sell shares of common stock, which strengthened its cash position, and extended its cash runway to fund operations into the third quarter of 2024.

Second Quarter 2022 Financial Results

Keros reported a net loss of $27.3 million in the second quarter of 2022 as compared to a net loss of $15.6 million in the second quarter of 2021. The increase in net loss for the second quarter was largely due to increased research and development efforts as well as additional infrastructure expenses to support the achievement of Keros' corporate goals.

Research and development expenses were $23.3 million for the second quarter of 2022 as compared to $10.0 million for the same period in 2021. The increase of $13.3 million was primarily due to additional research and development efforts, manufacturing activities, and personnel expenses to support the advancement of Keros' pipeline.

General and administrative expenses were $7.4 million for the second quarter of 2022 as compared to $5.7 million for the same period in 2021. The increase of $1.8 million was primarily due to increase in personnel expenses and other external expenses to support Keros' organizational growth.



Keros’ cash and cash equivalents as of June 30, 2022 was $215.6 million compared to $230.0 million as of December 31, 2021. Keros expects that the cash and cash equivalents it had on hand at June 30, 2022 will fund its operating expenses and capital expenditure requirements into the third quarter of 2024.
