Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Received any prior external beam radiation treatment to the liver
- Received any prior yttrium-90 microsphere treatment to the liver
- Received previous peptide receptor radionuclide therapy (PRRT)
- Presence of ongoing adverse event due to prior therapy as judged by the principal investigator or sub-investigator to affect the safety evaluation of the study device.
- Previous liver function decompensation within the last 6 months (ascites, encephalopathy, jaundice)
- Have any disease or condition that would preclude the safe use of BSJ019T, including concurrent dialysis treatment, or unresolved serious infections
- Participating in concurrent clinical studies or interventional clinical studies
- Previous gastrointestinal bleeding related to portal hypertension within the last 3 months (preventive treatment is acceptable)
- \[Exclusion Criteria based on the imaging evaluation\]
Other illness
- Vp4 according to the Liver Cancer Study Group of Japan (LCSGJ) portal vein tumor thrombosis classification1
- History of severe allergy or intolerance to contrast agents, narcotics sedatives or atropine that cannot be managed medically.
- Evidence of pulmonary insufficiency or clinically evident chronic obstructive pulmonary disease
- Patient with infiltrative disease presentation (not suitable for repeated measurement)
- Any condition where the Investigator feels the patient would not be able to participate/finish the study
Other
- \[Exclusion Criteria based on the clinical evaluation\]
- Contraindications to angiography and selective visceral catheterization
- Plan to start systemic anticancer treatment in the next 3 month after the index procedure.
- Undergone any intervention for, or compromise of, the Ampulla of Vater within that last 3 months or patient with biliodigestive anastomosis.
- Presence of ascites, clinical or radiological, "trace" of ascites is acceptable.
- Presence of Hepatic encephalopathy (Grade ≥2)
- Patients who are pregnant or breast-feeding and does not want to stop.
- Dose to the lung \> 30Gy for a single treatment or cumulative \>50 Gy
- Evidence of any off-target extrahepatic and liver deposition on 99mTc-MAA that cannot be corrected using angiographic techniques
- Cone Beam CT (CBCT) or 99mTc-MAA hepatic arterial perfusion scintigraphy shows poor tumor perfusion and/or poor tumor targeting that would lead to a dose that does not meet the liver dosing criteria as specify in the protocol
Who the study is looking for
- \[Inclusion criteria based on the clinical evaluation\]
- Patient aged \>18 years at time of consent
- Patient is able and willing to participate in the study and has provided written informed consent
- Patient who is determined to have failed or not be eligible for standard treatment by the multidisciplinary board
- Primary or secondary liver cancer (by histology or imaging)
- Measurable disease defined as at least one uni-dimensional measurable liver lesion by CT/MRI (according to RECIST 1.1)
- Liver dominant disease (patient prognosis is driven by liver tumor)
- Tumor replacement \<50% of total liver volume based on visual estimation by the investigator
- Expected life expectancy ≥ 3 months or more from the index procedure
- ECOG Performance Status score of 0 or 1
- Negative pregnancy test in women of child-bearing potential
- Adequate contraception for the patient and his/her sexual partner when applicable.
- Adequate liver function, as defined by:
- Child Pugh A or to B7 (HCC)
- Must have bilirubin ≤ 2 mg/dL
- ALT and AST must be \<5 x ULN
- Albumin ≥3.0 g/dL
- Adequate renal function, as defined by:
- Serum creatinine must be ≤1.5 x ULN
- Adequate hematological function, as defined by:
- Neutrophil count \> 1200 /mm3
- hemoglobin ≥85 mg/L
- platelet count \>50 x 109/L
- INR must be \<2.0 or \>50% prothrombin activity
- \[Inclusion Criteria based on the imaging evaluation\]
- After 99mTc MAA administration, in SPECT/CT imaging, good PVT targeting and uptake of 99mTc MAA, if present
- Future liver remnant volume (FLRV) \>30% of whole liver volume. FRLV is the volume of liver not planned to be treated with TheraSphere and free of tumor
