Study Overview

Brief Summary

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

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.

Inclusion Criteria

  • Male or female patients aged of at least 18 years on day of signing informed consent.
  • Histologically-confirmed diagnosis of any histological type of solid tumors, excluding primary central nervous system (CNS) tumors.
  • Radiological evidence by MRI : At least one and a maximum of 5 brain metastases, and at least one brain lesion with a longest diameter ≥ 2 cm and eligible for FSRT.
  • Patient without progression on extracranial disease documented by radiological assessment as per RECIST v1.1 within 4 weeks before inclusion.
  • For patients treated with a systemic anti-cancer therapy: a minimal 2-week washout period is required from the date of last systemic treatment administration to Day 1, except for hormonal agents.
  • ECOG Performance Status (PS) ≤
  • Absolute neutrophil count (ANC) ≥ 1.0 G/L, Platelets ≥ 75 G/L, Hemoglobin ≥ 8 g/dL, Serum creatinine OR Creatinine clearance according to CKD-EPI ≤ 1.5 x Upper Limit of Normal (ULN) OR ≥ 50 mL/min/1.73m2, ASAT and ALAT ≤ 3 x ULN (or ≤ 5.0 ULN in case of liver metastasis or hepatic infiltration),INR and Activated Partial Thromboplastin Time (aPTT) ≤1.5 x ULN.
  • Women of child-bearing potential must have a negative serum pregnancy test at screening and must agree to use 2 effective forms of contraception from the time of the negative pregnancy test up to 3 months after the last dose of the study drug.
  • Fertile men must agree to use contraceptive measures up to 3 months after the last dose of study drug.
  • Patients who understand, sign, and date the written voluntary informed consent form at the screening visit prior to any protocol-specific procedures. Patient should be able and willing to comply with study visits and procedures as per protocol.
  • Patients must be covered by a medical insurance.

Exclusion Criteria

  • Prior local treatment with radiotherapy (whole / partial brain or stereotactic radiosurgery) or surgical resection of brain lesions.
  • Patient participating to another clinical trial with an investigational agent.
  • Patients who have not recovered from significant adverse events (i.e. Grade > 2 AE according to NCI CTCAE v5.0) due to prior treatment with anti-cancer agents with exception of any Grade alopecia or lab values presented in inclusion criteria.
  • Contra-indication for MRI enhanced with gadolinium (e.g. cardiac pacemaker, implanted defibrillator, certain cardiac valve replacements, certain metal implants).
  • Patients who are pregnant or breastfeeding.

Outcomes

Primary Outcomes

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 Outcomes

  • Tumor target volume(4 days)
  • Adverse events(From Day 1 to Day 45)
  • Distant Brain failure(6 month and at 1 year)
  • Time to brain relapse(6 month and 1 year)
  • Brain lesion 3-D volume variation(45 days and 3 month)
  • FACT-Br(45 days, 3 month, 6 month, 9 month and 12 month)
  • MMSE(45 days, 3 month, 6 month, 9 month and 12 month)
