CAMBRIDGE, Mass. and COPENHAGEN, Denmark, May 21, 2026 (GLOBE NEWSWIRE) -- Hemab Therapeutics Holdings, Inc., a clinical-stage biotechnology company developing therapies that reimagine the treatment of blood coagulation disorders to sustain life and human resilience, today announced financial results for the first quarter ended March 31, 2026 and noted recent business highlights.

“As a public company we continue our journey to accelerate progress and broaden impact for people living with serious coagulation disorders with strong momentum across our clinical programs,” said Benny Sørensen, Chief Executive Officer of Hemab Therapeutics. “The Breakthrough Therapy Designation for sutacimig in Glanzmann thrombasthenia recognizes both the potential for sutacimig to address a significant unmet need, and the urgency of bringing new treatment options to people living with Glanzmann thrombasthenia. With the successful completion of our IPO, our team remains focused on advancing sutacimig toward pivotal trials, advancing HMB-002, while continuing to expand our pipeline with the goal of bringing new therapies to those living with high unmet need coagulation disorders.”

Corporate Highlights

In May 2026, the Company completed an upsized IPO of 19,262,500 shares of its common stock, including the exercise in full of the underwriters’ option to purchase an additional 2,512,500 shares, at a public offering price of $18.00 per share. The offering raised gross proceeds of $346.7 million before deducting underwriting discounts and commissions and offering expenses payable by the Company. The Company’s common stock is now trading on the Nasdaq Global Select Market under the ticker symbol “COAG”.

Recent Business Highlights and Anticipated Milestones

Sutacimig: Sutacimig, a bispecific antibody, is the Company's most advanced product candidate. The Company is advancing the clinical development of sutacimig for two indications: Glanzmann thrombasthenia (GT) and Factor VII Deficiency.

Glanzmann Thrombasthenia:

GT is a serious inherited bleeding disorder with a prevalence of between 1 in 350,000 and 1 in 600,000 in the United States and caused by defects in platelet aggregation. Current treatment options are limited to platelet transfusions, antifibrinolytics, recombinant Factor VIIa, and bone marrow transplantation.

• The Company is conducting a Phase 1/2 clinical trial of sutacimig in patients with GT. Part B of the trial, which evaluated the safety and tolerability profile of sutacimig and explored clinical efficacy over three months at multiple dose levels, is complete, and patients are continuing treatment with sutacimig in the long-term extension portion of the trial.
• In March, sutacimig received Breakthrough Therapy Designation from the US Food and Drug Administration (FDA) for GT, a designation awarded to medicines that treat serious or life-threatening conditions where preliminary clinical evidence suggests the potential for a substantial improvement over the current standard of care.
• The Company is preparing for a planned Phase 3 pivotal clinical trial in patients with GT that it anticipates initiating in the second half of 2026.
• Sutacimig has received Orphan Drug Designation from both the FDA and the European Medicines Agency (EMA) for the treatment of GT.
  
  

Factor VII Deficiency

Factor VII deficiency is a serious inherited coagulation disorder affecting approximately 1 in 500,000 people globally, that is characterized by impaired blood clotting and increased bleeding risk.

• The Company is conducting an ongoing Phase 2 clinical trial of sutacimig for Factor VII deficiency. The Company expects to report data from the trial in late 2026 or early 2027.
  
  

HMB-002 - Von Willebrand Disease

HMB-002 is a novel monovalent antibody designed for subcutaneous prophylactic treatment of Von Willebrand Disease (VWD), one of the most common inherited bleeding disorders affecting approximately 140,000 patients.

• The Company is evaluating HMB-002 in an ongoing Phase 1/2 clinical trial. The Company expects to report data from the trial in late 2026 or early 2027.
  
  

Pipeline Expansion

The Company is also advancing multiple preclinical and discovery-stage assets focused on coagulation disorders with the goal of addressing critical gaps in the treatment landscape.

First Quarter 2026 Financial Results

• Cash Position and Cash Runway: Cash, cash equivalents, and marketable securities totaled $163.5 million as of March 31, 2026, compared to $185.5 million as of December 31, 2025. The Company believes its current cash, cash equivalents, and marketable securities, together with net proceeds from the initial public offering completed in May 2026 of approximately $317.2 million, will enable it to fund its operating expenses and capital expenditure requirements into 2029.
• Research and Development Expenses: Research and development expenses were $19.5 million for the three months ended March 31, 2026, compared to $14.1 million for the three months ended March 31, 2025, reflecting advancement of clinical programs and regulatory activities.
• General and Administrative Expenses: General and administrative expenses were $4.2 million for the three months ended March 31, 2026, compared to $2.5 million for the three months ended March 31, 2025, including costs associated with preparing for and completing the initial public offering.
• Net Loss: Net loss was $22.7 million, or $23.98 per share, for the three months ended March 31, 2026, compared to a net loss of $15.3 million, or $16.18 per share, for the three months ended March 31, 2025.
