Strengthened Board and Leadership Team

NANTES, France - March 26, 2025, 6:15 p.m. CET - OSE Immunotherapeutics SA (ISIN: FR0012127173; Mnemo: OSE), a biotech company dedicated to developing first-in-class therapies in immuno-oncology and immuno-inflammation, today announced its consolidated annual financial results for 2024, along with key updates on proprietary programs as well as licensed assets, and the Company's outlook for 2025.

"2024 was transformative for OSE, marked by positive efficacy results, major partnerships, and accelerated preclinical programs. We signed strategic agreements with AbbVie and Boehringer Ingelheim, strengthening our financial position and bolstering our capabilities in immuno-inflammation and immuno-oncology.

"Lusvertikimab showed positive and clinically meaningful Phase 2 induction results for ulcerative colitis, proving its excellent efficacy and safety profile, with further data to be presented at the Digestive Disease Week conference in San Diego in May, for the 24-week open-label extension period. This success, built on 10 years of research and development by the OSE teams, reinforces our confidence in Lusvertikimab's promise. It serves as a strong catalyst to explore the best strategic opportunities for its further development in a maintenance study in ulcerative colitis, as well as other chronic autoimmune and inflammatory diseases.

"In immuno-oncology, we launched Artemia, the global pivotal Phase 3 study of Tedopi® monotherapy in Non-Small Cell Lung Cancer (NSCLC) second-line treatment in patients with secondary resistance to immune checkpoint inhibitors. Everything is on track. The study leverages our previous randomized positive efficacy results from NSCLC third-line treatment. We are also pleased with the positive topline results in pancreatic cancer, which will be presented at an upcoming medical conference this year. Additionally, we expect further combination study readouts in ovarian and lung cancer in 2026.

"With over €90 million non-dilutive cash accumulated in 2024, and a cash runway until 2027, we are well-positioned to develop novel therapeutic options for patients, supported by our strong and diversified clinical and pre-clinical portfolio, and our dedicated expert teams. Going forward, we will prioritize and strategically advance our two late-stage proprietary programs, aiming to fully realize their potential and create significant value for patients and our shareholders,” said Nicolas Poirier, CEO of OSE Immunotherapeutics.

THREE PHARMACEUTICAL AGREEMENTS SIGNED in H1 2024 STRENGTHEN FINANCIAL POSITION TO SUPPORT STRATEGY IMPLEMENTATION UNTIL 2027

  • February 2024: OSE Immunotherapeutics and AbbVie signed a licensing and collaboration agreement to develop ABBV-230 (formerly OSE-230), a monoclonal antibody designed to resolve chronic and severe inflammation. AbbVie received an exclusive global license to develop, manufacture and commercialize ABBV-230. OSE Immunotherapeutics received a $48 million upfront payment and is eligible for up to $665 million in clinical development, regulatory and commercial milestones, plus potential tiered royalties on global net sales.
  • May 2024: OSE Immunotherapeutics and Boehringer Ingelheim announced a major expansion of their partnership:
    • Amended licensing and collaboration agreement for SIRPα programs in immuno-oncology and metabolic associated steatohepatitis (MASH): a one-time payment of €25.3 million. All other agreed development, regulatory and sales milestone payments of up to €1.1 billion remain as agreed between the parties under the initial agreement.
    • New asset acquisition from OSE's cis-targeting anti-PD1/cytokine platform: €13.5 million received upon signature and a €17.5 million potential near-term milestone.
MAJOR CLINICAL ADVANCES OF TWO LATE-STAGE ASSETS

Anti-IL-7R Lusvertikimab in ulcerative colitis (UC): Significant clinical and preclinical advances were presented at ECCO 2025 (Top 10 congress highlights) and a KOL webinar:

  • Efficacy and Safety: Lusvertikimab showed high rates of clinical and endoscopic remission, histological improvement, and Histo-Endoscopic Mucosal Improvement (HEMI) with a favorable safety profile.
  • Subgroup analysis: Early promising efficacy signals in both biologic-naïve and experienced populations, from a week 10 induction study (two to four weeks earlier than many contemporary studies) indicate rapid onset of effect, suggesting potential as a first-line biologic or for patients resistant to anti-TNF and anti-IL-12/23 therapies by addressing upstream (IL-7) pathway mechanisms.
  • Future Data: Additional efficacy and safety data from the 24-week open-label extension period will be presented in May 2025 at the Digestive Disease Week conference in San Diego. Pre-and post-treatment mucosal and peripheral biomarkers are under exploration.
  • Strategic Evaluation: development in a maintenance study in UC is being explored, as well as expansion to other Th1 and Th17-related diseases with strong biological and translational IL-7 rational. We are considering various strategic options to support these initiatives and ultimately create value for patients and shareholders.
Tedopi® Clinical Trials Update:

  • ARTEMIA: Launched international pivotal Phase 3 trial in September 2024 comparing Tedopi monotherapy to standard of care docetaxel for second-line treatment of HLA-A2 positive patients with metastatic NSCLC and secondary resistance to immune checkpoint inhibitors.
  • TEDOPaM: Achieved primary endpoint of one-year overall survival rate in March 2025, for Phase 2 trial in HLA-A2 positive patients with advanced pancreatic cancer. Results to be shared at upcoming oncology congress this year by study sponsor, GERCOR Group.
  • TEDOVA: Completed Phase 2 trial enrollment in December 2024 in HLA-A2 positive patients with ovarian cancer (alone or in combination with pembrolizumab), led by French oncology group ARCAGY-GINECO. Readout expected in Q2 2026.
  • CombiTED: Patient enrollment on track to complete in Q2 2025 for Phase 2 trial in second-line HLA-A2 positive patients with NSCLC in combination with nivolumab or docetaxel. The trial is led by Italian foundation FoRT. Readouts are expected in H2 2026.
  • Tedopi® + OSE-279: Positive Phase 1 efficacy and safety results announced in February 2024 of OSE-279 monotherapy; ongoing evaluation of Tedopi® + OSE-279 in first-line HLA-A2 positive patients with NSCLC with PD-L1≥50%.

PROGRESS ON PARTNERED ASSETS

  • Positive Phase 1/2 analysis of pegrizeprument (FR104/VEL-101) immunotherapy in kidney transplantation: In June 2024, OSE Immunotherapeutics and Nantes University Hospital presented positive data from the Phase 1/2 FIRsT trial at the American Transplant Congress (ATC) in Philadelphia. The data demonstrated the safety and initial efficacy of pegrizeprument in combination therapy. Veloxis Pharmaceuticals also featured Phase 1 dose escalation results for subcutaneous administration of pegrizeprument, which will facilitate dose selection in preparation for a Phase 2 study in kidney transplant recipients.
  • Advancement of first-in-class SIRPα treatment BI 770371: In July 2024, Boehringer Ingelheim and OSE Immunotherapeutics announced progression of their first-in-class SIRPα immuno-oncology program. Boehringer Ingelheim will advance a next generation SIRPα inhibitor antibody in Phase 1b for solid tumors (first-line metastatic or recurrent head and neck squamous cell carcinomas) and in Phase 2 for MASH-related compensated cirrhosis.
  • Advancement of AbbVie Inc. and OSE Immunotherapeutics strategic partnership to develop ABBV-230: in April 2024, the Hart-Scott-Rodino waiting period expired enabling teams to commence work around the transfer of technology and preparation for moving the asset from pre-clinical to a Phase 1 clinical trial.

PROGRESS ON PRECLINICAL PROGRAMS

OSE Immunotherapeutics announced significant advancements in 2024, including a CAR cell therapy commercial and revenue sharing agreement with Memorial Sloan Kettering Center and updates on novel CLEC-1 immune checkpoint or pro-resolutive mAb research, IL-35 mRNA therapeutic preclinical proof of concept data, and established a strategic AI collaboration in the field of Precision Immunotherapy in 2025.
