OSE Immunotherapeutics has launched a Phase 3 clinical trial to evaluate the efficacy and safety of OSE2101, a therapeutic cancer vaccine, compared to Docetaxel in patients with metastatic non-small cell lung cancer (NSCLC) who have developed secondary resistance to immune checkpoint inhibitors. This study is significant as it targets HLA-A2 positive patients, aiming to provide an alternative treatment for those who have limited options after resistance to standard therapies.
The intervention being tested is OSE2101, a peptidic cancer vaccine designed to target specific tumor-associated antigens. It is administered via subcutaneous injection, with a regimen that adjusts over a two-year period. The control group receives Docetaxel, a well-known chemotherapy drug, through intravenous infusion.
The study follows a randomized, open-label design with two parallel groups. There is no masking involved, and the primary purpose is treatment. This straightforward design allows for a clear comparison between the new vaccine and the existing chemotherapy option.
The study began on December 3, 2024, with primary completion expected in the near future. The latest update was submitted on July 9, 2025, indicating ongoing recruitment and progress. These dates are crucial for tracking the study’s development and potential market entry.
This clinical update could positively influence OSE Immunotherapeutics’ stock performance by showcasing progress in their innovative cancer treatment pipeline. Investors may view this as a promising development, especially if OSE2101 proves effective. The competitive landscape includes other companies developing cancer vaccines, but OSE’s focus on NSCLC with secondary resistance offers a unique market position.
The study is currently ongoing, with further details accessible on the ClinicalTrials portal.
