clinical trial

Servier and French biotech company OSE Immunotherapeutics SA have completed patient enrollment in a phase 2a clinical trial evaluating the efficacy and safety of monoclonal antibody OSE-127/S95011 in primary Sjögren’s syndrome.

The international, randomized, double-blind, placebo-controlled, phase 2a study is designed to evaluate the efficacy and tolerance of the monoclonal antibody OSE-127/S95011 in primary Sjögren’s syndrome

The study includes 48 patients across the U.S., Australia and Europe. Results are expected in 2023.

Important step for Servier and OSE Immunotherapeutics

Patricia Belissa-Mathiot, Servier’s director of clinical development and R&D chief medical officer, said: “We are humbled with the progress of this clinical study and look forward to announcing the initial results in the coming year. Primary Sjögren’s syndrome, one of the most common systemic autoimmune diseases, is a disease with significant unmet need and we are grateful to the patients for their participation in this study.”

Nicolas Poirier, chief executive officer of OSE Immunotherapeutics said: “We are thankful for our partnership with Servier as we continue to progress this phase 2a clinical trial, which represents an important step forward in determining the clinical safety and efficacy of OSE-127/S95011 for patients living with Sjögren’s syndrome.”

OSE-127/S95011, for which Servier has worldwide rights, is being developed in a partnership between OSE Immunotherapeutics and Servier via a collaboration agreement, with the possibility for Servier to exercise a licensing option. Two clinical studies evaluating OSE-127/S95011 are ongoing: a phase 2a study conducted by Servier in primary Sjögren’s syndrome and a phase 2 study conducted by OSE Immunotherapeutics in ulcerative colitis.
