NANTES, France--(BUSINESS WIRE)--Regulatory News:
OSE Immunotherapeutics SA (Paris:OSE) (ISIN: FR0012127173; Mnémo: OSE) today announced authorization by Federal Agency for Medicines and Health Products (FAMH) and Belgian Ethics Committee to initiate a Phase 1 clinical trial of OSE-127, a monoclonal antibody targeting the IL-7 Receptor (IL-7R) with a novel mechanism of action(1).
The first-in-human dose-escalation Phase 1 clinical study aims to evaluate the safety and tolerability of single- and multiple-ascending intravenous and subcutaneous doses of OSE-127. A total of 63 healthy volunteers will be enrolled in this randomized, double-blind, placebo-controlled study.
Alexis Peyroles, CEO of OSE Immunotherapeutics, said: “Initiating this Phase 1 study represents a leap forward for OSE-127. On the heels of publishing the unique mechanism of action of OSE-127 in Nature Communications(1), we believe even more strongly that this asset has significant potential therapeutic value for treatment of autoimmune diseases and chronic inflammation.”
Specifically targeting IL-7R expression, which has previously been shown to be predictive for non-response to inflammatory bowel disease treatments, and by enhancing regulatory T lymphocytes in the mucosa, OSE-127 offers a differentiated mechanistic profile in debilitating autoimmune conditions, such as intestinal bowel diseases.
OSE-127 is being developed under an option license agreement with Servier* up to the completion of a Phase 2 clinical trial, planned in ulcerative colitis, a bowel autoimmune disease, and in parallel in Sjögren’s syndrome.
*Servier is an independent international pharmaceutical company governed by a foundation with Headquarters based in France.
OSE-127 is a monoclonal immunomodulatory antibody targeting the CD127 receptor, the alpha chain of the interleukin-7 receptor (IL-7R) that induces a powerful antagonist effect on effector T lymphocytes. Interleukin-7 is a cytokine which specifically regulates the tissue migration of human effector T lymphocytes, especially in the gut. The blockage of IL-7R prevents the migration of pathogenic T lymphocytes while preserving regulator T lymphocytes (2,3) which have a positive impact in autoimmune diseases.
OSE Immunotherapeutics has signed a license option agreement with Servier in December 2016 for the development and commercialization of OSE-127.

ABOUT OSE Immunotherapeutics
OSE Immunotherapeutics is a clinical-stage biotechnology company focused on developing and partnering therapies to control the immune system for immuno-oncology and autoimmmune diseases. The company has a diversified first-in-class clinical portfolio consisting of several scientific and technological platforms including neoepitopes and agonist or antagonist monoclonal antibodies, all ideally positioned to fight cancer and autoimmune diseases. Our most advanced asset, Tedopi®, is a proprietary combination of 10 neo-epitopes aimed at stimulating T-lymphocytes and is currently in Phase 3 development in non-small cell lung cancer (NSCLC) after checkpoint inhibitor failure (anti PD-1 and anti PD-L1). In April 2018, Boehringer Ingelheim and OSE signed a global license and collaboration agreement to develop checkpoint inhibitor OSE-172 (anti-SIRPa monoclonal antibody) in multiple cancer indications. In July 2016, Janssen Biotech exercised a licensing option to continue clinical development of FR104 (an anti-CD28 mAb) in auto-immune diseases after positive Phase 1 results; termination of licence agreement effective Dec. 31, 2018 due to strategic portfolio prioritization and OSE regained all worldwide rights on this asset. In 2016, Servier signed a two-step license option to develop OSE-127 (monoclonal antibody targeting the CD127 receptor, the alpha chain of the interleukin-7 receptor) up to the completion of a Phase 2 clinical trial planned in autoimmune bowel diseases; in parallel, Servier plans a development in the Sjögren syndrome.
