OSE Immunotherapeutics Presents Update on BiCKI®-IL-7v and CLEC-1 Immuno-Oncology Programs at International Conferences

At the Society for Immunotherapy of Cancer (SITC 2022) and
At the Macrophage-directed Therapies Summit 2022

Nantes, France – October 12, 2022, 6:00 p.m. CET – OSE Immunotherapeutics SA (ISIN: FR0012127173; Mnemo: OSE) today announced that three posters have been accepted for presentation at the Society for Immunotherapy of Cancer (SITC) 37^th Annual Meeting which will be held in person and virtually in Boston, MA,  November 8 – 12. The posters will feature the latest preclinical data on the Company’s pioneering drug discovery BiCKI® and Myeloid platforms and including BiCKI®-IL-7 (bifunctional therapy targeting PD-1 and IL-7) and CLEC-1 (new myeloid immune checkpoint). The Company was also invited for an oral presentation at the Macrophage-directed Therapies Summit of its CLEC-1 program (Boston, October 2022).

ABOUT OSE Immunotherapeutics

OSE Immunotherapeutics is a biotech company dedicated to developing first-in-class assets in immuno-oncology and immuno-inflammation. 

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

·        Tedopi® (T-cell specific immunotherapy, off-the-shelf, neoepitope-based): 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): advanced preclinical stage.

·        OSE-127/S95011 (humanized monoclonal antibody antagonist of IL-7 receptor) developed in partnership with Servier; ongoing Phase 2 in ulcerative colitis (sponsor OSE Immunotherapeutics) and ongoing Phase 2a in Sjögren’s syndrome (sponsor Servier).

·        VEL-101/FR104 (anti-CD28 monoclonal antibody): developed in partnership with Veloxis Pharmaceuticals, Inc. in transplantation; ongoing Phase 1/2 in renal transplant (sponsor Nantes University Hospital); Phase 1 ongoing in the US (sponsor Veloxis Pharmaceuticals, Inc.).

·        BI 765063 (anti-SIRPα monoclonal antibody on CD47/SIRPα pathway): developed in partnership with Boehringer Ingelheim in advanced solid tumors; positive Phase 1 dose escalation results of BI 765063 in monotherapy and in combination, in particular with anti-PD-1 antibody ezabenlimab; BI sponsored international Phase 1b ongoing clinical trial in combination with ezabenlimab alone or with other drugs in patients with recurrent/metastatic head and neck squamous cell carcinoma (HNSCC) and hepatocellular carcinoma (HCC).    

OSE Immunotherapeutics expects to generate further significant value from its two proprietary R&D platforms, which are central to its ambitious goal to deliver next-generation first-in-class immunotherapeutics:

·      BiCKI® platform focused on immuno-oncology (IO) is a bispecific fusion protein platform built on the key backbone component of anti-PD1 combined with a new immunotherapy target to increase anti-tumor efficacy. The most advanced BiCKI® candidate is targeting anti-PD1xIL-7.

·      Myeloid platform focused on optimizing the therapeutic potential of myeloid cells in IO and immuno-inflammation (I&I). OSE-230 (ChemR23 agonist mAb) is the most advanced candidate generated by the platform, with the potential to resolve chronic inflammation by driving affected tissues to tissue integrity.
