OSE Immunotherapeutics Granted Approval to Resume Patient Accrual in U. S. for Phase 3 Tedopi® Clinical Trial in Advanced Non-Small Cell Lung Cancer Patients Following Immune Checkpoint Inhibitor Treatment


Posted on: 27 Feb 18

NANTES, France, Feb. 27, 2018 (GLOBE NEWSWIRE) -- OSE Immunotherapeutics (ISIN:FR0012127173) (Mnémo:OSE), today announces that the first approvals to resume patient accrual in the global Tedopi® Phase 3 trial have been granted in the United States by the Institutional Review Boards. Recruitment into this trial is based on a revised protocol focused on patients with Non-Small Cell Lung Cancer (NSCLC) who have failed a previous treatment with PD-1/PD-L1 immune checkpoint inhibitors.

The U.S. is the first region in which the trial will resume patient accrual under the revised protocol. By focusing exclusively on NSCLC patients who have failed a previous treatment with PD-1/PD-L1 immune checkpoint inhibitors, Tedopi® has the potential to address a significant unmet medical need, as no product is currently approved for the treatment of this population in immune escape.

The trial will be conducted in two steps:

  1. Enrollment of approximately 100 patients and a performance analysis of the survival data, with results expected in approximately two years.
  2. Based on this analysis, the observed clinical benefit of Tedopi® will determine the registration strategy to be implemented in a second step.

"We are pleased to resume recruitment in this Tedopi® Phase 3 study, with a design that addresses the treatment needs of a specific patient population, for whom there is currently no approved therapeutic option. We warmly thank all of the clinical investigators participating in this clinical trial for their continued support," said Dominique Costantini, Chief Executive Officer of OSE Immunotherapeutics.

The Tedopi® Phase 3 trial, Atalante 1, is evaluating the benefit of Tedopi® in HLA-A2 positive patients with NSCLC at invasive stage IIIB or metastatic stage IV, in 2nd or 3rd line treatment following failure of a checkpoint inhibitor, compared to current standard chemotherapy treatments in this patient population. The primary endpoint of the trial is overall survival.

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 neoepitopes 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. In February 2018, the first approvals to resume patient accrual have been granted in the United States by the Institutional Review Boards.
    • 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.
