Keros Therapeutics Announces Global License Agreement with Takeda to Advance Elritercept

Keros Therapeutics to receive upfront payment of $200 million and is eligible to receive development, approval and commercial milestone payments with the potential to exceed $1.1 billion and tiered royalties on net sales

LEXINGTON, Mass., Dec. 03, 2024 (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 announced an exclusive global development and commercialization license agreement with Takeda (TSE:4502/NYSE:TAK) to advance elritercept. Elritercept is currently in two ongoing Phase 2 clinical trials; one in patients with very low-, low-, or intermediate-risk myelodysplastic syndrome (“MDS”) and one in patients with myelofibrosis (“MF”). The Phase 3 RENEW clinical trial evaluating elritercept in adult patients with transfusion-dependent anemia with very low-, low-, or intermediate-risk MDS will begin enrollment soon.

Under the terms of the agreement, Takeda will obtain an exclusive license to further develop, manufacture and commercialize elritercept worldwide outside of mainland China, Hong Kong and Macau. Takeda will be responsible for all development, manufacturing and commercialization as of the effective date of the agreement. Subject to the terms of the agreement, Keros will receive a $200 million upfront cash payment and is eligible to receive development, approval and commercial milestones with the potential to exceed $1.1 billion. Keros will also be eligible to receive tiered royalties on net sales.

“We are thrilled to announce this agreement with Takeda, a leader in the hematologic oncology treatment space,” said Jasbir S. Seehra, Ph.D., Chair and Chief Executive Officer of Keros. “We believe this global license further validates Keros’ position as a leader in understanding the role of the TGF-ß family of proteins and the broad potential of this biological pathway.”

“We believe Takeda is an ideal partner to maximize the potential of elritercept’s differentiated profile and continue to build on the great progress our team has accomplished with elritercept,” said Chris Rovaldi, President and Chief Operating Officer of Keros. “We expect that the net proceeds from the upfront payment will enable us to extend our operational runway into the fourth quarter of 2028, facilitating the continued advancement of cibotercept (KER-012) and KER-065, both of which are wholly-owned assets with near term clinical updates.”

“We are excited to partner with Keros, an accomplished team with exceptional expertise in TGF-ß biology,” said P.K. Morrow, Head of the Oncology Therapeutic Area Unit at Takeda. “Building on the promising results elritercept has shown in the clinic to date, we look forward to continuing to explore its potential and to having the opportunity to potentially deliver it to patients with hematologic disorders. This agreement aligns with our goal of advancing therapies that may shift the treatment paradigm for underserved patient populations.”

The effectiveness of the agreement is subject to clearance under the Hart-Scott-Rodino Antitrust Improvements Act (“HSR Act”).

About Elritercept

Elritercept is an engineered ligand trap comprised of a modified ligand-binding domain of the TGF-ß receptor known as activin receptor type IIA that is fused to the portion of the human antibody known as the Fc domain. Elritercept is being developed for the treatment of low blood cell counts, or cytopenias, including anemia and thrombocytopenia, in patients with MDS and in patients with MF.
