OSE Immunotherapeutics Receives Notice of Allowance for New Patent by U.S. Patent and Trademark Office that Further Strengthens Intellectual Property Portfolio Around Tedopi® in Immuno-Oncology Applications

NANTES, France, Jan. 25, 2018 (GLOBE NEWSWIRE) — OSE Immunotherapeutics (ISIN:FR0012127173) (Mnémo:OSE), today announces that it has received a notice of allowance from the U.S. Patent and Trademark Office (USPTO) for a new patent that further expands the Company’s intellectual property portfolio around Tedopi®, a combination of neoepitopes optimised to induce specific T activation in immuno-oncology.

The new patent extends the U.S. protection of Tedopi® to several combinations of  neoepitopes (peptides from various tumourous antigens optimized to bind strongly with HLA-A2 and T lymphocyte receptors) for use in cancer treatment, complementary to those already covered under existing intellectual property. Tedopi®, being evaluated in a Phase 3 clinical trial in patients with advanced or metastatic non-small cell lung cancer (NSCLC), was previously granted orphan drug designation in the U.S. in this indication.   

“Following this patent being granted in Europe, Australia, Canada and Japan, this allowance from the USPTO significantly strengthens the patent protection of Tedopi® and reinforces its position as a key product in our immuno-oncology portfolio. Patient accrual in the Phase 3 trial in advanced lung cancer will resume in the first quarter of 2018, upon approval by the competent authorities of the program’s new recruitment strategy, which is focused on a subgroup of patients who have failed a previous treatment with immune checkpoint inhibitors. The trial addresses a specific population for which there are currently no approved treatment options, and for which a significant medical need exists,” said Dominique Costantini, CEO of OSE Immunotherapeutics.

Tedopi® is a combination of 10 neoepitopes that generate a specific response from the T cytotoxic cells against the malignant cells, which express at least one of these tumorous antigens and an associated T helper response.

ABOUT OSE IMMUNOTHERAPEUTICS
Our ambition is to become a world leader in activation and regulation immunotherapies:
OSE Immunotherapeutics is a biotechnology company focused on the development of innovative immunotherapies for immune activation and regulation in the fields of immuno-oncology, autoimmune diseases and transplantation. The company has several scientific and technological platforms: neoepitopes, agonist or antagonist monoclonal antibodies, ideally positioned to fight cancer and autoimmune diseases. Its first-in-class clinical portfolio offers a diversified risk profile.

In immuno-oncology:

  • Tedopi®, 10 combined neo-epitopes to induce a specific T lymphocyte activation. Phase III trial in advanced NSCLC: after temporary pause of new patient accrual end of June 2017, new recruitment strategy in December 2017, following the recommendation of the trial’s Independent Data Monitoring Committee, to focus the trial on patients who failed a previous treatment with a PD-1/PD-L1 immune checkpoint inhibitor. Enrollment will resume after formal approval of the new recruitment strategy from the Competent Authorities.
    Phase II with Tedopi® in combination with an immune checkpoint inhibitor planned in advanced pancreatic cancer, in collaboration with GERCOR, a cooperative group of clinical research.
  • OSE-172, new generation checkpoint inhibitor targeting myeloid cells via the SIRP-α receptor – In preclinical development for several cancer models. Clinical program planned end of 2018.
  • OSE-703, cytotoxic monoclonal antibody against the alpha chain of IL-7R – Under a research collaboration with Memorial Sloan Kettering Cancer Center, New York.

In auto-immune diseases and transplantation:

  • FR104, CD28-antagonist in immunotherapy – Phase 1 trial completed – For the treatment of autoimmune diseases and for use with transplantation – Licensed to Janssen Biotech Inc. to pursue clinical development.
  • OSE-127, interleukin receptor-7 antagonist – In preclinical development for inflammatory bowel diseases and other autoimmune diseases. Clinical phase planned end of 2018. License option agreement with Servier for the development and commercialization.

The portfolio’s blockbuster potential gives OSE Immunotherapeutics the ability to enter global agreements at different stages of development with major pharmaceutical players.
Immunotherapy is a highly promising and growing market. By 2023 Immunotherapy of cancer could represent nearly 60% of treatments against less than 3% at present * and the projected market is estimated at $67 billion in 2018 **. There are more than 80 autoimmune diseases that represent a significant market including major players in the pharmaceutical industry with sales towards $10 billion for the main products. The medical need is largely unmet and requires the provision of new innovative products involved in the regulation of the immune system.
