Galecto Announces Acquisition of Damora Therapeutics

Acquisition of Damora and concurrent oversubscribed $285 million private investment positions the company to advance potentially best-in-class portfolio to improve outcomes in patients with Myeloproliferative Neoplasms

Damora Therapeutics, the sixth company launched based on assets developed by Paragon Therapeutics, is advancing a portfolio of anti-mutant calreticulin (mutCALR) targeted therapies, led by DMR-001, a potentially best-in-class monoclonal antibody targeting

mutCALR

Combined company with complementary assets expected to have financial runway into 2029 to support multiple data milestones, including Phase 1 clinical proof-of-concept data for DMR-001 anticipated in 2027

BOSTON, November 10, 2025 – Galecto, Inc. (“Galecto”) today announced the completion of the acquisition of Damora Therapeutics, Inc. (“Damora”), a privately held biotechnology company advancing a pipeline of antibody therapeutics aimed at transforming the treatment of mutant calreticulin- (mutCALR)-driven Myeloproliferative Neoplasms (MPNs), including Essential Thrombocythemia (ET) and Myelofibrosis (MF). The acquisition gives the combined company a pipeline covering a broad spectrum of hematological cancers and leverages the deep expertise of both teams, and positions Galecto to advance Damora’s complementary assets for people living with blood cancers, with the goal of developing safer, more effective, and more convenient disease-modifying therapies.

A concurrent private placement of Series C non-voting convertible preferred stock was led by Fairmount with participation from the following institutional investors: Viking Global Investors, Venrock Healthcare Capital Partners, Commodore Capital, Janus Henderson Investors, Wellington Management, RA Capital Management, TCGX, Forbion, BB Biotech, Blackstone Multi-Asset Investing, Perceptive Advisors, Vestal Point Capital, Balyasny Asset Management, Andreessen Horowitz (a16z Bio + Health), and a leading life sciences investment firm. The private placement resulted in gross proceeds to Galecto of approximately $284.9 million and is expected to fund operations into 2029, enabling advancement of Damora’s lead program, DMR-001, through key Phase 1 proof-of-concept data expected in 2027, as well as pipeline programs, DMR-002 and DMR-003, into Phase 1 studies.

MPNs are a group of rare, chronic blood cancers characterized by the abnormal production of blood cells in the bone marrow. MutCALRs drive uncontrolled proliferation and disease progression in 25% of ET and 35% of MF cases. There are approximately 42,000 patients in the United States living with mutCALR-driven MPNs.

Damora is the sixth company launched based on assets developed by Paragon Therapeutics. DMR-001 is a potentially best-in-class anti-mutCALR monoclonal antibody demonstrated to have enhanced activity in Type 1 and Type 2 mutCALR-driven preclinical models, with approximately 10-fold greater potency against Type 2 mutCALR-driven cell proliferation, as compared to internal data generated using a reference molecule in clinical development, supporting its potential to address the full spectrum of mutCALR mutations in both ET and MF. DMR-001 is engineered with validated half-life extension technology to enable infrequent low-volume, subcutaneous dosing. An IND submission for DMR-001, with anticipated first-in-human administration via subcutaneous administration, is expected to occur in mid-2026.

“The acquisition of Damora marks a pivotal milestone for Galecto as we evolve our focus toward advancing Damora’s highly differentiated mutCALR portfolio, which addresses significant unmet need across the full spectrum of blood cancers driven by mutCALR,” said Dr. Hans Schambye, President and CEO of Galecto. “This pipeline, led by DMR-001, is designed to overcome the limitations of current candidates in early clinical development and has the potential to establish a new standard of care in the treatment of ET and MF. With a strong balance sheet, we believe we are well-positioned to drive these programs rapidly into the clinic and ultimately deliver meaningful benefit to patients.”

“The immediate access to public capital markets and the strengthened financial position achieved through this acquisition and concurrent private placement provides momentum to accelerate the development of our highly specialized portfolio,” added Peter Harwin, incoming Galecto Board Member and Managing Member at Fairmount. “Our team is eager to leverage Galecto’s infrastructure to rapidly transition DMR-001 from IND-enabling studies to first-in-human trials by mid-2026, ensuring these assets, focused on superior efficacy and convenience, reach patients as quickly as possible.”

In addition, Galecto is excited to combine these newly acquired complementary pipeline assets with its investigational candidate GB3226, a dual ENL-YEATS and FLT3 inhibitor for multiple genetic subsets of acute myeloid leukemia (AML). As previously disclosed, GB3226 will be featured in two poster presentations at the 67th American Society of Hematology (ASH) Annual Meeting and Exposition, taking place December 6 – 9, 2025, in Orlando, Florida. Galecto also announced that it received constructive feedback from the U.S. Food and Drug Administration (FDA) in response to its pre-Investigational New Drug (pre-IND) submission and plans to submit an IND application in the first quarter of 2026 to enable future clinical evaluation of GB3226 in AML.
