Key inclusion & exclusion criteria

Secondary cancer, Liver metastases

Inclusion criteria:

- Age = 18

- Written Informed Consent obtained, signed and dated

- ECOG performance status 0 or 1

- Life expectancy > 6 months

- Liver metastases from other primary cancers 1) with histologic confirmation of
metastases, or 2) History of primary cancer with histology available and lesions in
the liver consistent with metastases, or 3) histologic confirmation of primary cancer
and a growing enhancing lesion in the liver consistent with a metastasis

- Unresectable tumor/s, based on the opinion of an experienced surgeon specializing in
hepatic resection, or the patient must be medically inoperable

- Patients with extra-hepatic metastases controlled by supportive care or concomitant
hormonotherapy are eligible.

- Previous liver resection or local treatment (radiofrequency ablative therapy,
chemoembolization, microwave treatment…) is permitted

- Patients must have recovered from the effects of previous therapy (residual AE grade 0
or 1)

- Radiological disease progression according to the investigator evaluation or according
to RECIST 1.1

- At least one tumor lesion that can be accurately measured in at least one dimension
according to RECIST 1.1

- Normal permeability of hepatic artery evaluated by injected CT-scan (arterial phase)

- Total target volume of lesions < 500cc and < 50% of the total liver volume

- 700 cc of liver volume without tumor involvement and a radiation therapy dose < 15 Gy

- The following laboratory parameters:

- Platelet count = 50 x 10^9/L

- Hemoglobin = 8.5 g/dL

- Absolute neutrophil count = 1.5 x 10^9/L,

- Prothrombin rate (PR)> 50%

- International Normalized Ratio (INR) < 1.5 or correctable with vitamin K. Patients
receiving anti-coagulation or anti-aggregation therapy must stop temporarily during
treatment.

- Total bilirubin <30 µmol/l

- Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) = 5 x upper limit
of normal

- Albumin >2.5 g/dL

- Very low or undetectable HBV DNA and HCV RNA

- Serum Creatinine = 1.5 time the upper limit of normal value

- Glomerular Filtration Rate > 44mL/min/1.73m2

- All female patients of childbearing potential must have a negative serum/urinary
pregnancy test within the 7 days prior to NBTXR3 administration. Otherwise, Patients
must be post-menopausal, surgically sterile, or using 'effective contraception'. The
definition of 'effective contraception' will be based on the judgment of the
investigator.

Exclusion criteria:

- Patients with ongoing chronic active viral B or C hepatitis must have received an
antiviral treatment with negative or very low viremia before the onset of the
radiation therapy

- Biliary tract dilatation, biliodigestive anastomosis, bile duct drainage

- Uncontrolled extra-hepatic metastatic disease with a symptomatic treatment or well
tolerated hormonotherapy (AE 0/1)

- Previous anticancer treatment (chemotherapy or/and biologicals) with a wash out < 4
weeks

- Previous treatment with intra-arterial injection of Y90 loaded microspheres in the
same hepatic lobe than the current tumor.

- Previous intra-arterial chemotherapy

- Prior radiation therapy to the right upper abdomen, precluding re-irradiation of the
liver. That is, any previous radiation therapy in which a mean dose to the liver of 15
Gy in conventional fractionation was delivered, or previous doses to critical normal
structures that would make re-irradiation unsafe

- Impossibility to follow the dosimetry constraints (mean total liver dose > 15Gy)

- Presence of arterio-venous intra tumoral shunting

- Encephalopathy related to liver failure

- Clinical ascitis

- Presence of another scalable tumor disease except cervical carcinoma in situ, treated
basal cell carcinoma, or superficial bladder tumors (Ta, Tis &T1)

study entry is permitted)

- Active, clinically severe bacterial or fungal infections (> grade 2 NCI-CTCAE, version
5.0)

- Complete initial work up earlier than 4 weeks prior to patient registration

- Patient whose general health condition does not allow treatment feasibility

- Patients unable and/or unwilling to comply with scheduled visits, treatment plans,
laboratory tests, and other study procedures

- Patients participating in another clinical investigation at the time of signature of
the informed consent.
