OSE Immunotherapeutics to Present New Data on Tedopi® from Phase 3 Clinical Trial in Patients with Advanced Non-Small Cell Lung Cancer after Failure to Immune Checkpoint Inhibitors at ESMO Congress 2022
NANTES, France--(BUSINESS WIRE)--Regulatory News:
OSE Immunotherapeutics SA (ISIN: FR0012127173; Mnemo: OSE) announces the presentation of two new analyses from the Phase 3 Atalante-1 study of immunotherapy Tedopi®, in patients with advanced non-small cell lung cancer (NSCLC) in secondary resistance after failure of previous checkpoint inhibitor treatments, at the 2022 European Society for Medical Oncology (ESMO) Congress, being held September 9-13, in Paris.
Alexis Vandier, Chief Executive Officer of OSE Immunotherapeutics, commented: "In patients with no treatment option after failure of two therapeutic classes, in particular post-checkpoint inhibitors, Tedopi® has shown an overall clinical benefit in this phase 3 study, integrating both efficacy and tolerance compared to chemotherapy treatments. This new specific immunotherapy offers prospects for therapeutic management, both in monotherapy and in combination, and we will do our best to make this treatment available as soon as possible for these patients.”
The first analysis compared Tedopi® to the Standard of Care (SoC) in patients with advanced NSCLC after secondary resistance to sequential use of chemotherapy followed by immunotherapy (CT-IO).
The results have shown that in advanced HLA-A2+ NSCLC patients with IO secondary resistance after sequential CT-IO (n=118), overall survival (OS) was longer with Tedopi® versus SoC regardless of the use (or not) of post progression anticancer treatment (with 13.5 months versus 10.6, HR=0.71; without 6.3 months versus 4.5, HR=0.76).
This analysis will be presented by Dr Maria Rosario Garcia Campelo (Head of Medical Oncology Department, Thoracic Tumors Unit, Investigator of Atalante-1 study, University Hospital A Coruña, Spain).
Dr Garcia Campelo said: “There is a strong medical need for a new therapeutic alternative in these heavily pretreated NSCLC patients, aiming not only at a prolonged survival but desiring a maintained global health status.”
The second analysis assessed the overall benefit/risk of Tedopi® versus SoC chemotherapy in patients with NSCLC who failed therapy with immune checkpoint inhibitors. The Net Treatment Benefit (NTB)*, a new statistical method combining efficacy, safety and quality of life, was assessed in the overall population (n=219). NTB of Tedopi® was of 19% and reached statistical significance (p=0.035).
This analysis will be presented by Dr Marc Buyse, (Founder and Chief Scientific Officer, International Drug Development Institute (IDDI), Brussels, Belgium).
*The Net Benefit of a treatment should take the correlation between benefits and harms into account Marc Buyse et al.; Journal of Clinical Epidemiology, 2021.
