Antwerp, Belgium, August 6, 2026 – Agomab Therapeutics NV (Nasdaq: AGMB) (“Agomab”), a clinical-stage biopharmaceutical company focused on fibro-inflammation, today reported financial results for the half year period ended June 30, 2026, and confirmed its outlook for the second half of 2026.

“In the first half of 2026, we continued to execute on our clinical and operational strategy, and we are on track with the clinical read-outs and trial initiations of ontunisertib and AGMB-447 expected later this year,” said Tim Knotnerus, Chief Executive Officer of Agomab. “Our recent engagement with the FDA provides important support for our development strategy with ontunisertib, and we believe the NOV-ERA Phase 2b study will be a crucial next step in evaluating ontunisertib’s potential as a differentiated therapy to address the high unmet medical need in FSCD. As we head into a catalyst-rich second half of 2026, we especially look forward to the OLE results with ontunisertib and first IPF data with AGMB-447.”

Pierre Kemula, Chief Financial Officer of Agomab, added, “The first half of 2026 marked a defining moment for Agomab, with our Nasdaq IPO raising $208 million in gross proceeds, extending the cash runway into the first half of 2029. We are well-resourced to drive our clinical programs forward with both focus and discipline. As we look ahead to important milestones across our fibro-inflammatory disease portfolio, we are well positioned to deliver meaningful value for patients and shareholders alike.”

First Half 2026 Program Highlights and Anticipated Milestones

• Ontunisertib (AGMB-129), a gut-restricted small molecule inhibitor of ALK5 for the treatment of FSCD
• • We announced the design of the NOV-ERA study, a randomized, double-blind, placebo-controlled, dose-ranging, multicenter Phase 2b trial designed to evaluate the efficacy and safety of ontunisertib in adults with symptomatic FSCD. We have aligned with the FDA on the NOV-ERA design, including the study’s primary efficacy endpoint of endoscopic passability at Week 24 as assessed by the SES-CD narrowing score, as well as several secondary efficacy endpoints relevant to patients with FSCD.
    
  • The protocol has been submitted to the FDA and has cleared central Institutional Review Board (IRB) approval in the U.S. In addition, the study has received approval by Health Canada and the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK. The Company has also submitted Clinical Trial Applications (CTAs) in multiple countries globally, including in the European Union and Asia Pacific territories. We plan to initiate the NOV-ERA study following receipt of applicable regulatory and ethics approvals and expect to dose the first participants in the second half of 2026.
  • We are progressing the OLE part of the STENOVA study (Part B) with ontunisertib in FSCD patients, with topline results expected in the coming months. The 48-week data may provide important insights into extended treatment with ontunisertib in FSCD patients.
  • As of February 2026, the Data Safety and Monitoring Board has not raised any safety issue and has recommended for the OLE study to continue as per the protocol with 200mg BID ontunisertib for up to 60 weeks.
  • The results of the 12-week placebo-controlled double-blind part of the STENOVA Phase 2a study with ontunisertib in FSCD (Part A) were presented as a late-breaker at the 21^st Congress of ECCO (ECCO’26) in Stockholm, Sweden in February 2026. The late-breaking presentation was also featured by Nature Reviews Gastroenterology & Hepatology as one of the highlights of ECCO’26. 

• AGMB-447, an inhaled small molecule inhibitor of ALK5 in development for the treatment of IPF
  
  
  • In January 2026, we announced positive interim results of the Phase 1 study of AGMB-447 in 108 healthy participants. The data pointed to a generally favorable safety, tolerability and pharmacokinetic profile of AGMB-447, with robust target engagement of ALK5 observed in the lungs of healthy participants.
    
  • We have enrolled 10 participants in the IPF cohort of the Phase 1b study with AGMB-447. In this cohort, participants receive multiple doses of AGMB-447 or placebo over 14 days. We expect to report topline results from the IPF patient cohort in the coming months.
  • We are on track to initiate a Phase 2 trial with AGMB-447 in IPF in the second half of the year.
  • We were granted a patent covering the composition of matter of AGMB-447 by the United States Patent and Trademark Office (USPTO), solidifying the foundational intellectual property for AGMB-447 in the U.S. 

Half Year 2026 Financial Results (consolidated)

• Cash Position: Cash, cash equivalents and short-term cash investments totaled €252.0 million as of June 30, 2026. In February 2026, we completed our IPO, in which we raised gross proceeds of approximately $208 million, including the proceeds from the underwriters’ partial exercise of their overallotment option, before deducting underwriting discounts and commissions and other offering expenses. We expect that our existing cash and cash investments, including the net proceeds from our IPO, will enable us to fund our operating expenses and capital expenditure requirements into the first half of 2029.
• R&D Expenses: Research and development (R&D) expenses were €23.0 million for the six months ended June 30, 2026, as compared with €22.0 million for the six months ended June 30, 2025.
• G&A Expenses: General and administrative (G&A) expenses were €12.2 million for the six months ended June 30, 2026, as compared with €6.7 million for the six months ended June 30,2025. The increase of €5.5 million for the period mainly relates to one-off expenses incurred for the IPO.
• Net Loss: Net loss was €31.0 million for the six months ended June 30, 2026, compared to €26.9 million for the six months ended June 30, 2025.

Ontunisertib and AGMB-447 are investigational drugs and not approved by any regulatory authority. Their efficacy and safety have not been established.

About ontunisertib

Ontunisertib (AGMB-129) is an oral small molecule GI-restricted inhibitor of ALK5 (or TGF-β RI) currently in clinical development for the treatment of Fibrostenosing Crohn’s Disease (FSCD). TGF-β is a major driver of fibrosis. Ontunisertib is specifically designed to inhibit ALK5/TGF-β in the GI-tract. Rapid first-pass metabolism in the liver prevents clinically relevant systemic exposure, potentially delivering an improved safety profile over systemically available inhibitors in this class. Ontunisertib has received U.S. FDA Fast Track Designation.

About Fibrostenosing Crohn’s Disease

Crohn’s disease is a chronic progressive disease of the gastrointestinal tract. It is estimated that approximately 46% of patients with Crohn’s disease have fibrosis of the gastrointestinal tract, resulting in stricture formation and intestinal obstructions, most frequently in the terminal ileum. These strictures can cause obstructive symptoms leading to dietary change, malnutrition and surgery. Despite the large unmet medical need, there are no approved pharmacological therapies for FSCD.
