About this study
Official title: An Open-label, Prospective, Multi-center Clinical Trial to Evaluate the Efficacy and Safety of Ablative Radioembolization Using Yttrium-90 Glass Microspheres in Patients With Locally-advanced Hepatocellular Carcinoma
The RESOLVE trial, an open-label, single-arm, multi-center study, aims to assess the efficacy and safety of ablative radioembolization using TheraSphere Yttrium-90 microspheres. This trial specifically targets patients diagnosed with hepatocellular carcinoma accompanied by localized portal vein tumor thrombosis (Vp1-Vp3) and who maintain good liver function.
Read the detailed description
Patients diagnosed with unilobar hepatocellular carcinoma and localized portal vein tumor thrombosis (Vp1-Vp3), who also exhibit good liver function, will undergo ablative radioembolization with a dose exceeding 205 Gy to the tumor using TheraSphere glass microspheres. These patients will be monitored over a two-year period to evaluate their clinical course, treatment outcomes, and safety.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Ablative radioembolizationProcedure or surgery
The interventional radiologist utilizes a pre-test with 99mTc-MAA SPECT-CT and cone-beam CT for procedural planning. For tumors confined to a single segment, the treatment area is planned to receive a radiation dose of over 400 Gy using the single-compartment MIRD technique. For tumors extending beyond a single segment, the multi-compartment MIRD technique is used to plan a radiation dose of 700 Gy (± 20%) to the tumor. The upper limit for the estimated lung dose is set at 25 Gy, and the upper limit for the perfused non-tumoral liver dose is 250 Gy. In cases where tumors extending beyond a single segment cannot receive the planned dose of 700 Gy (± 20%) due to limits on lung or normal liver dose, the plan is adjusted to deliver the maximum dose to the tumor within the permissible range for lung and normal liver doses. Radioembolization is typically performed in a single session, and any methods not mentioned here should follow the instructions for use of TheraSphere.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Ablative radioembolization in people with Hepatocellular Carcinoma, run by Seoul National University Hospital at 5 sites in South Korea.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 22 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 20 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Jin Woo Choi, MD, PhD (+82-220722584, jwchoi.med@snu.ac.kr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overall survival (time frame: Time of treatment up to participant's death, opposition to data collection, lost to follow-up, or study termination (24 months after the last patient is enrolled)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06166576, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Aug 2026; AzTrials last refreshed its copy on 8 Nov 2026.
