An interventional study of TheraSphere Y-90 glass microsphere in Liver Neoplasms, sponsored by Boston Scientific Corporation. Recruiting at 4 sites in Japan. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-08-20.
Sponsored by Boston Scientific Corporation · Not applicable, Interventional, and Treatment
To investigate the safety and effectiveness of BSJ019T in Japanese patients with primary or secondary liver who are not candidate for standard treatment.

[Exclusion Criteria based on the imaging evaluation]
Device: TheraSphere Y-90 glass microsphere
TheraSphere Y-90 glass microsphere therapy administered through the hepatic artery at index procedure.
Rate of hepatic disease control (DCR = complete response [CR], partial response [PR] or stable disease [SD]) at 3 months using the localized RECIST 1.1 criteria.
Time frame: 3-months post index procedure
Rate of objective response (ORR = complete response [CR] or partial response [PR]) at 3 months using the localized RECIST 1.1 criteria and localized mRECIST
Time frame: 3-months post index procedure
Rate of hepatic disease control (DCR) and objective response (ORR) at 6 months using localized RECIST 1.1 and localized mRECIST criteria
Time frame: 6-months post index procedure
Best response using localized RECIST 1.1 and localized mRECIST criteria.
Time frame: Through 6-months post index procedure
Proportion of patient receiving concomitant and post BSJ019T treatment, including subsequent local and systemic anticancer treatment, surgery, intervention and best supportive care.
Time frame: Through 6-months post index procedure
Safety assessment: rate of treatment emergent adverse events (TEAEs) of any grade, rate of grade 3 or above TEAEs, rate of SAEs of any causality and rate of SAEs related to treatment with TheraSphere.
All AEs will be evaluated using the standardized grading criteria (National Cancer Institute- Common Terminology Criteria for Adverse Events- Version 5.0 (NCI-CTCAE v 5.0))
Time frame: Through 6-months post index procedure
Technical success in delivering the Y-90 microspheres
Technical success is determined successful if residual waste is ≦2% with optimal tumor targeting and extrahepatic deposition is not seen on post treatment imaging, and the success rate of entire of the subjects will be summarized.
Time frame: During the index procedure
Health-related quality of life (HRQoL) using EQ-5D questionnaires at regular intervals
Time frame: Baseline, 1-, 3- and 6-months post treatment
Health-related quality of life (HRQoL) using FACT-G questionnaires at regular intervals
Time frame: Baseline, 1-, 3- and 6-months post treatment
Overall survival
Time frame: Through study completion, an average of 1 year
