ABOUT OSE PHARMA
OSE Pharma is a biotech company that designs and develops cancer immunotherapy treatments using its Memopi® technology, through "neo-epitopes” (small synthetic peptides chemically modified to increase the binding the HLA A2 or TCR receptors) which triggers a cytotoxic T-cell response and leads the immune system to destroy cancer cells. More than 10,000 epitopes were selected.

Its lead product Tedopi® (OSE-2101) combines 10 optimized "neo-epitopes” simultaneously acting against 5 tumor-associated antigens (TAAs). These 5 antigens have been selected because they are a factor of poor prognosis in several types of cancers. The 10 optimized "neo-epitopes” have been selected and modified to enhance their binding to HLA-A2 and TCR receptors, and trigger a stronger T-cell response. These strong cytotoxic T-cell responses lead the immune system to destroy tumor cells expressing HLA-A2 antigens and one of the targeted tumor antigens (TCR).

The most advanced clinical stage of Tedopi® is a pivotal Phase 3 study to be launched soon in Europe and in the U.S. in patients diagnosed with non-small cell lung cancer (NSCLC). It will target patients whose cells are expressing HLA-A2 antigens, a key receptor for the cytotoxic T-immune response that can be found in nearly 45% of patients with lung cancer. Patients expressing the HLA-A2 positive receptor are those responsive to Tedopi®®. The trial will focus on patients with stage IIIb (invasive) or stage IV (metastatic) NSCLC after at least one first line therapy failure. Its objective will be to evaluate the benefits of Tedopi® compared to current standard chemotherapy treatments (docetaxel or pemetrexed) in this patient population. The primary endpoint of this trial will be overall survival (the Phase 2 study demonstrated a long survival of patients, considering how advanced their pathology was). 500 patients will be included in Europe and in the U.S.

Tedopi® can be developed in Phase 2 in combination with other immunotherapeutic products or targeted therapies. It is also considered for other oncology indications (ovary, colontriple negative breast cancer) for HLA-A2 positive patients.
