- Planned Phase 2 Studies in Ulcerative Colitis and Sjögren’s Syndrome to Start in 2020
NANTES, France I December 02, 2019 I OSE Immunotherapeutics (ISIN: FR0012127173; Mnémo: OSE) today announced completion and positive results from the Phase 1 study of OSE-127, a humanized monoclonal antibody with a differentiated mechanism of action as a full-antagonist of the CD127 receptor, the alpha chain of the interleukin-7 receptor (IL-7R). OSE-127 has been shown in previous studies to induce a powerful antagonistic effect on effector T lymphocytes responsible for causing autoimmune diseases.
The Phase 1 study results show a good safety and tolerability profile for OSE-127. All pharmacokinetic and pharmacodynamic parameters are consistent and demonstrate a dose-proportionality across the several dose-levels up to 10 mg/kg. These findings will help determine the dosing and administration schedule for the two planned Phase 2 trials in ulcerative colitis and Sjögren’s syndrome. Both trial initiations are expected in 2020.
“These encouraging Phase 1 findings, together with the novel and differentiated mechanism of action of OSE-127, the only full-antagonist of IL-7R, provide a firm foundation for further clinical development. These data support the potential of this compound to be a relevant therapy in ulcerative colitis, a chronic inflammatory bowel disease, representing 12.2 per 100,000 people by year* and Sjögren’s syndrome, representing 7 per 100,000 people by year**. We look forward to evaluating the product’s efficacy in both indications through two independent Phase 2 studies expected to be initiated in 2020,” said Alexis Peyroles, Chief Executive Officer of OSE Immunotherapeutics.
This study was a first-in-human dose-escalation, randomized, double-blind, placebo-controlled Phase 1 trial, aimed to evaluate the safety and tolerability of single- and multiple-ascending intravenous and subcutaneous doses of OSE-127 in 63 healthy volunteers. Secondary endpoints included measures of pharmacokinetics, pharmacodynamics and immunogenicity to help assess and understand how the drug is absorbed and metabolized.
OSE-127 is being developed in partnership with Servier¹ under an option agreement up to the completion of a Phase 2 clinical trial planned in autoimmune bowel diseases. In parallel, Servier plans to develop OSE-127 in Sjögren’s syndrome.
¹ Servier is an independent international pharmaceutical company, governed by a non-profit foundation, with headquarters based in France.

ABOUT OSE-127
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 which have a positive impact in autoimmune diseases.
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 autoimmune 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. The most advanced therapeutic-candidate, 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) in patients in failure after checkpoint inhibitor treatment (anti PD-1 and anti PD-L1) and in Phase 2 testing in pancreatic cancer in combination with checkpoint inhibitor Opdivo®. BI 765063 (OSE-172) (anti-SIRPa monoclonal antibody) is under a license and collaboration agreement with Boehringer Ingelheim; this checkpoint inhibitor is currently under Phase 1 clinical trial in advanced solid tumors. BiCKI® is a bispecific fusion protein platform built on the key backbone component anti-PD-1 (OSE-279) and targeting innovative targets. FR104 (an anti-CD28 mAb) has successfully completed Phase 1 testing and has potential to treat autoimmune diseases. OSE-127 (monoclonal antibody targeting the CD127 receptor, the alpha chain of the interleukin-7 receptor) is partnered with Servier under an option agreement up to the completion of a Phase 2 clinical trial planned in autoimmune bowel diseases; in parallel, Servier plans a development in the Sjögren’s syndrome. The Phase 1 clinical phase of OSE-127 is completed and has shown positive results; planned Phase 2 studies in ulcerative colitis and Sjögren’s syndrome to start in 2020.
