OSE Immunotherapeutics unveiled on October 19 the first results of the Combi-TED trial, selected for an oral presentation at the ESMO congress. The two combinations associating Tedopi with docetaxel or nivolumab achieved the one-year overall survival criterion, with rates of 47% and 46%, respectively, compared to 29% for docetaxel alone. The press release also mentions higher rates of adverse events in the combined arms than in the reference arm.

On September 28, the company indicated it had liquidity funded until the end of 2026 and was continuing discussions with investors in the United States and Europe. Its third-quarter cash position will be published on October 27.
