OSE Immunotherapeutics SA announced the departure of Alexis Peyroles as Chief Executive Officer. Dominique Costantini, current Chairwoman of OSE Immunotherapeutics' Board of Directors, and previously CEO from 2012 to 2018, has been appointed interim Chief Executive Officer, effective immediately. A search for a new CEO has been launched with the assistance of a leading executive search firm.

Alexis Peyroles is stepping down for health reasons and he remains committed to OSE's success. He will continue to support the company in a consulting capacity for the upcoming months to ensure a smooth transition. During this transition period, Dominique Costantini will rely on OSE's reinforced leadership team, including notably Laurence de Schoulepnikoff, Chief Business Officer, appointed as Chief Operating Officer of the Company, functions which she previously held at AMAL Therapeutics.
