Brief Summary:
This study evaluates the clinical impact of AGuIX® nanoparticles in combination with Fractionated Stereotactic Radiation in oligo brain metastases.

Condition or disease Intervention/treatment Phase
Brain Metastases Drug: AGuIX Phase 2

Detailed Description:

AGuIX® (Activation and Guidance of Irradiation by X-ray, NH TherAguix) are Gadolinium chelated polysiloxane based nanoparticles with Magnetic Resonance contrast properties, able to accumulate in the tumor through the enhanced permeability and retention effect and sufficiently small (sub-5 nm diameter) to allow for renal clearance.

AGuIX® nanomedicine can be used as:

  • Positive contrast agent for Magnetic Resonance Imaging (MRI). It displays higher efficacy than commercial contrast agents and so it can be used to delineate precisely the tumors.
  • A booster of Radiotherapy during the radiotherapy protocol, after the localization of the tumor.

This is permitted by the high radiosensitizing potential of AGuIX® that allows a local increase of efficacy of X-ray damages. French and international groups have demonstrated the radiosensitizer effect of AGuIX® to improve the efficacy of radiotherapy.

Thanks to a difference in porosity between the vascular networks, AGuIX® penetrates and resides in tumor tissues, but not in healthy tissues.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 55 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Intervention Model Description: This study is a paucicentric, single arm Phase II trial conducted according to a single stage Fleming-A'Hern design and aiming to evaluate the efficacy of AGuIX® during FSRT of brain metastasis.
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase II Study Evaluating AGuIX® Nanoparticles in Combination With Stereotactic Radiation for Oligo Brain Metastases.
Actual Study Start Date : January 17, 2020
Estimated Primary Completion Date : April 2021
Estimated Study Completion Date : April 2022

Arm Intervention/treatment
Experimental: Aguix + Stereotactic Radiation Drug: AGuIX
2 IV injections (100 mg/Kg/injection) at day 4 and day 8 + Strereotactic Radiation from day 8 to day 15 as per standard practice.

Primary Outcome Measures :
  1. Rate of local control [ Time Frame: 1 year ]
    The primary endpoint is the rate of local control defined as the proportion of patients with a complete response, a partial response or a stable disease. Response of Brain lesion will be evaluated using the RECIST classifications with partial response (PR, > 30% decrease in longest diameter), stable disease (SD <30% decrease and <20% increase in longest diameter), progressive disease (PD > 20% increase in longest diameter) and Complete response (CR) (complete disappearance of the brain lesion).

Secondary Outcome Measures :
  1. Distant Brain failure [ Time Frame: 6 month and at 1 year ]
    Distant Brain failure is defined as the presence of new brain metastases or leptomeningeal enhancement outside the irradiated volume.

  2. Time to brain relapse [ Time Frame: 6 month and 1 year ]
    The event of interest will be the local progression on any irradiated lesion.

  3. Tumor target volume [ Time Frame: 4 days ]
    The Tumor target volume agreement is the comparison between both the MRI images with AGuIX® and Gd-chelates. It is defined as the correlation between the irradiation volume calculated based on the MRI before nanoparticles injection and the volume calculated after nanoparticles injection.

  4. Brain lesion 3-D volume variation [ Time Frame: 45 days and 3 month ]
    Brain lesion 3-D volume variation will be analysed using volumetric T1 post-gadolinium MRI.

  5. Adverse events [ Time Frame: From Day 1 to Day 45 ]
    The assessment of safety will be based mainly on the frequency of adverse events based on the common toxicity criteria (CTCAE-V5.0) grade.

  6. FACT-Br [ Time Frame: 45 days, 3 month, 6 month, 9 month and 12 month ]
    The FACT-Br consists of a general version (FACT-G) and a brain subscale (BRCS). The FACT-G consist of 27 questions with 4 domains assessing physical well-being (score range: 0-28), social/family well-being (score range: 0-28), emotional well-being (score range: 0-24) and functional well-being (score range: 0-28). The BRCs is a 23-item questionnaire related to neurological concerns that provides an additional set of disease-specific questions pertaining to brain neoplasms (score range: 0-92). The FACT-Br total score is the sum of the FACT-G total score and the BrCS score. Positive change scores indicate improved quality of life.

  7. MMSE [ Time Frame: 45 days, 3 month, 6 month, 9 month and 12 month ]
    The MMSE is an 11-item measure that tests five areas of cognitive function: orientation, registration, attention and calculation, recall and language. The minimum score is 0 and the maximum score is 30 with higher MMSE scores indicating better cognition.
