2026-02-18

Odimma Therapeutics, a biotechnology company developing next-generation personalized cancer immunotherapies, today announced that the French National Agency for Medicines and Health Products Safety (ANSM) has authorized the Centre Georges François Leclerc (CGFL) to initiate a Phase I clinical trial of ODI-2001 in patients with solid tumors.

This authorization confirms that the manufacturing, quality, preclinical and clinical components of the clinical trial application have been reviewed and deemed acceptable for first-in-human administration. The study represents the first clinical evaluation of Odimma’s personalized immunotherapy platform.

ODI-2001 is a multi-component immunotherapy designed to induce tumor-specific immune responses through a personalized neoantigen approach combining synthetic DNA, Modified Vaccinia Ankara (MVA), and immune checkpoint blockade. The therapy is produced individually for each patient based on tumor-specific mutations.

The trial is sponsored by the Centre Georges François Leclerc (CGFL) in Dijon, France, and will be conducted at specialized oncology centers.

“This regulatory authorization marks a major milestone for Odimma Therapeutics as we transition into the clinical stage,” said Jean-Marc Limacher, MD, Chairman and Chief Medical Officer of Odimma Therapeutics. “It reflects the extensive development work required to establish a clinically applicable personalized immunotherapy platform.”

“Personalized neoantigen immunotherapies represent one of the most promising strategies to extend the benefit of immunotherapy to a broader population of patients. This study will evaluate the feasibility of manufacturing and administering an innovative individualized treatment in a real clinical setting, which represents an important step for the field,” said Prof. Ghiringhelli, MD, PhD, Principal Investigator of the study at the Centre Georges François Leclerc.

The Phase I study is designed to evaluate safety, tolerability, feasibility, as well as exploratory immunologic and clinical endpoints.
