About OSE PHARMA

OSE Pharma is a European cancer immunotherapy company with a multi-epitope technology named Memopi® that directs the body’s immune system to generate a specific cytotoxic T response to prevent cancer cell growth.

OSE Pharma’s lead product, Tedopi®, combines 10 "neo-epitopes” directed against five tumour associated antigens. In its most advanced application it is about to enter a pivotal Phase 3 study in patients with advanced non-small cell lung cancer (NSCLC) who express HLA-A2 and who have failed first line therapy. Tedopi® has orphan drug status in the USA and is considered as personalised medicine in Europe in HLA-A2 positive patients.

Tedopi® could also be developed in a new Phase 2 clinical trial in combination with another immunotherapy treatment in NSCLC.
Tedopi® targets five tumour associated antigens (TAA), selected because their presence is linked to a poor prognosis and the severity of various cancers. Tedopi® contains a total of ten optimised epitopes, or "neo- epitopes”, designed on the binding of HLA-A2 and TCR. These neo-epitopes generate strong specific T cytotoxic responses that fight cancer and prevent tumour escape. (ISIN: FR0012127173 ; Mnémo : OSE).
