Radiotherapy of Multiple Brain Metastases Using AGuIX®

Study Purpose

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.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT03818386
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

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.
