Informations complémentaires
Schéma : This is a Prospective Randomized Open Blinded Endpoint phase II clinical trial. The study will be adaptive: an interim analysis is planned after enrolment of 20 patients in each arm of treatment (WBRT and AGuIX® + WBRT), to select and continue the study with group(s) that present the best response rate to the experimental treatment (AGuIX® + WBRT).

The main endpoint will be evaluated by a blinded endpoint committee.

The occurrence of brain metastases is a common event in the history of cancer and negatively affects the life expectancy of patients. Their incidence varies between 15 and 50% according to the histologic types. Surgery, stereotactic radiosurgery, radiotherapy and chemotherapy are the main treatments currently proposed.

For patients with multiple brain metastases, whole brain radiation therapy (WBRT) remains the standard of care. However, the median overall survival is less than 6 months and new approaches need to be developed to improve treatment of these patients.

In this context, the weak control of the disease comes from three main factors: the multiplicity of the brain lesions, the radioresistance of certain histologies and the poor distribution of cytotoxic agents in brain metastases.

The use of radiosensitizing agents is here of great interest. The radiosensitizing agent chosen in this study is AGuIX®. It is a Gadolinium-chelated polysiloxane based nanoparticle developed by NH TherAguix company for its theranostic properties (radiosensitization and diagnosis by multimodal imaging). Preclinical studies have demonstrated the radiosensitizing effect of AGuIX® in vivo in 8 tumor models xenografted in rodents, and particularly in brain tumors.
