• The Company’s strategy to build a leading portfolio of best- and first-in-class cancer immunotherapies.
• OSE’s goal to position Tedopi® as a new standard of care in non-small cell lung cancer (NSCLC) after immune checkpoint inhibitor (ICI) failure and its ongoing clinical development as a maintenance therapy for ovarian and pancreatic cancers.
• Recent clinical data supporting development of first-in-class CD47/SIRPα pathway targeting antibody BI 765063 alone and in combination with anti-PD-1 ezabenlimab in solid tumours.
• OSE’s emerging best- and first-in-class immuno-oncology portfolio which includes a novel myeloid cell “Don’t Eat Me” signal targeting CLEC-1 and a bispecific antibody platform (BiCKI®) whose first candidate, BiCKI®-IL-7 both combines an anti-PD-1 and the cytokine signal interleukin-7 (IL-7).

Amongst the R&D Day’s key speakers are:

• Pr. Benjamin Besse, Director of Clinical Research at Gustave Roussy (Villejuif, France), will present the positive final results of the Phase 3 Tedopi® clinical program in NSCLC, called Atalante-1, as well as an overview of the current landscape in NSCLC post-ICI.
• Dr. Philippe Cassier, Medical Oncologist at Leon Berard Cancer Center (Lyon, France), will highlight Phase 1 results of BI 765063 alone and in combination with ezabenlimab.

ABOUT OSE Immunotherapeutics

OSE Immunotherapeutics is an integrated biotechnology company focused on developing and partnering therapies to control the immune system for immuno-oncology and autoimmune diseases. The company’s immunology research and development platform is focused on three areas: T-cell-based vaccination, Immuno-Oncology (focus on myeloid targets), Auto-immunity & Inflammation. Its balanced first-in-class clinical and preclinical portfolio has a diversified risk profile:

Vaccine platform

• Tedopi® (innovative combination of neoepitopes): the company’s most advanced product; positive final results of the Phase 3 trial (Atalante 1) in Non-Small Cell Lung Cancer patients after secondary resistance to checkpoint inhibitors.
  
  In Phase 2 in pancreatic cancer (TEDOPaM), sponsor GERCOR.
  
  In Phase 2 in ovary cancer, in combination with pembrolizumab (TEDOVA), sponsor ARCAGY-GINECO.
  
  In Phase 2 in non-small cell lung cancer in combination with nivolumab, sponsor Italian foundation FoRT.
• CoVepiT: a prophylactic second-generation vaccine against COVID-19, developed using SARS-CoV-2 optimized epitopes against multi variants. Positive preclinical and human ex vivo results. Voluntary and temporary Phase 1 enrollment suspension on-going (July 2021).
  
  

Immuno-oncology platform

• BI 765063 (OSE-172, anti-SIRPα mAb 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 or in combination with ezabenlimab (PD-1 antagonist); Expansion Phase 1 open for screening.
• CLEC-1 (novel myeloid checkpoint target): identification of mAb antagonists of CLEC-1 blocking the “Don’t Eat Me” signal that increase both tumor cell phagocytosis by macrophages and antigen capture by dendritic cells.
• BiCKI®: bispecific fusion protein platform built on the key backbone component anti-PD-1 (OSE-279) combined with new immunotherapy targets; 2^nd generation of PD-(L)1 inhibitors to increase antitumor efficacity.
  
  

Auto-immunity and inflammation platform

• FR104 (anti-CD28 monoclonal antibody): Licensing partnership agreement with Veloxis in the organ transplant market; ongoing Phase 1/2 in renal transplant (sponsored by the Nantes University Hospital); Phase 2-ready asset in an autoimmune disease indication.
• OSE-127/S95011 (humanized monoclonal antibody targeting IL-7 receptor): developed in partnership with Servier; positive Phase 1 results; in Phase 2 in ulcerative colitis (OSE sponsor) and an independent Phase 2a is being conducted in Sjögren’s syndrome (Servier sponsor).
• OSE-230 (ChemR23 agonist mAb): first-in-class therapeutic agent with the potential to resolve chronic inflammation by driving affected tissues to tissue integrity.
