These steps allow strategy implementation relying on both proprietary late-stage immunotherapy assets in oncology (Phase 3 in NSCLC to be launched) and inflammation (Phase 2 in Ulcerative Colitis with other potential indications), and in accelerating and strengthening first-in-class preclinical programs from its innovative discovery platforms.

Our business-model, which is based on recurrent and strategic pharmaceutical partnerships, has been reinforced and allows us to develop our first-in-class clinical late-stage multi-products. We look forward to reaching new milestones in 2024, a transformative year for the Company with potential clinical inflection points from our proprietary and partnered assets, the anti-IL-7R monoclonal antibody Lusvertikimab in Phase 2 in Ulcerative Colitis and cancer vaccine Tedopi® in pivotal Phase 3 in Non-Small Cell Lung Cancer. We are preparing the next steps of the Company’s growth via our promising preclinical programs in immuno-inflammation and immuno-oncology.”

Dominique Costantini, Chairwoman of OSE Immunotherapeutics, comments: “In just a few years, we have built a fully integrated biotech company with a rich and differentiated drug-candidate portfolio of both proprietary and partnered programs with pharmaceutical companies, highly recognized as experts in their development fields and markets. The OSE team has already delivered significant achievements and is working to discover and develop innovative immunotherapies. All these significant milestones position 2024 to be a transformational year for OSE with the ambition to become one of the key European biotechs in immunotherapy. We propose a strategic evolution of the Board of directors with both highly experienced and international pharmaceutical and financial experts who will be able to support the Company in its future strategic choice growth.”

The Company’s current well-balanced first-in-class clinical pipeline includes:

• Tedopi^® (immunotherapy activating tumor specific T-cells, off-the-shelf, neoepitope-based): this cancer vaccine is the Company’s most advanced product; positive results from the Phase 3 trial (Atalante 1) in Non-Small Cell Lung Cancer patients in secondary resistance after checkpoint inhibitor failure. Other Phase 2 trials, sponsored by clinical oncology groups, of Tedopi^® in combination are ongoing in solid tumors.
• OSE-279 (anti-PD1): first positive results in the ongoing Phase 1/2 in solid tumors.
• OSE-127 - lusvertikimab (humanized monoclonal antibody antagonist of IL-7 receptor); ongoing Phase 2 in Ulcerative Colitis (sponsor OSE Immunotherapeutics); ongoing preclinical research in leukemia (OSE Immunotherapeutics).
• FR-104/VEL-101 (anti-CD28 monoclonal antibody): developed in partnership with Veloxis Pharmaceuticals, Inc. in transplantation; ongoing Phase 1/2 in renal transplant (sponsor Nantes University Hospital); successful Phase 1 in the US (sponsor Veloxis Pharmaceuticals, Inc.).

OSE-230 (licensed to AbbVie) is the first candidate generated by the platform, additional discovery programs ongoing on new pro-resolutive GPCRs.
• Myeloid Checkpoint platform focused on optimizing the therapeutic potential of myeloid cells in IO by targeting immune regulatory receptors expressed by Macrophages and Dendritic cells. BI 765063 and BI 770371 (licensed to Boehringer Ingelheim) are the most advanced candidates generated by the platform. Ongoing additional discovery programs, in particular with positive preclinical results obtained in monotherapy with new anti-CLEC-1 mAbs.
