About this trial

This study is being done to help doctors improve how they treat liver tumors that cannot be removed by surgery or treated with standard ablation techniques. The researchers want to find out the best amount of radiation that needs to be delivered to completely destroy (or ablate) parts of the liver that have cancer.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Diagnosis of hepatocellular carcinoma (HCC), cholangiocarcinoma, or liver-dominant metastatic disease not amenable to surgical resection or ablation.

Age ≥18 years.

Child-Pugh class A or B liver function

Eastern Cooperative Oncology Group (ECOG) performance status of 0-2.

Disqualifiers

Extrahepatic metastases.

Pregnant or breastfeeding individuals.

Tumors requiring treatment of more than two Couinaud segments.

Known hypersensitivity to gadolinium-based contrast agents.

Trial design

Design model

Parallel

Treatments tested in this trial

  • Yttrium-90 Radiation Segmentectomy (Y90 RS) using glass microspheres

    Other intervention

    The objective of this study is to define an optimal "ablative dose" range for Y90 Radiation Segmentectomy that achieves complete sectoral ablation detectable on dual contrast MRI and to determine whether this dose-response relationship differs between cirrhotic and non-cirrhotic patients.

Treatment groups

30 Participants
are divided into 2 treatment groups
Group A: CirrhoticActive comparator 1 intervention
Group B: Non-cirrhoticActive comparator 1 intervention

Trial outcomes

Primary outcomes

1

Ablative Dose Threshold for Y90 Radiation Segmentectomy

To prospectively define the "ablative dose" threshold for Y90 Radiation Segmentectomy (RS) using post-treatment PET dosimetry and hepatobiliary phase MRI

Time frame
From enrollment to the end of post-treatment Y90 12 month follow up visit
2

Impact of Cirrhosis on Ablative Dose Requirements

To determine whether cirrhotic patients require a higher threshold dose for ablation compared to non- cirrhotic patients

Time frame
From enrollment to enrollment to post-treatment Y-90 12 month follow-up visit

Secondary outcomes

1

Correlation of Y90 Dose with Imaging Biomarkers

To evaluate the correlation between delivered Y90 dose and imaging biomarkers, including signal loss on hepatobiliary phase MRI, ablative margins, extracellular volume fraction, and perfusion changes

Time frame
Assessed at 1, 4-9, and 12 month follow up visits
2

Tumor Response and Time-to-Progression Assessment

To assess tumor response by mRECIST and determine time to progression (TTP)

Time frame
From enrollment to end of post-treatment Y-90 12 month follow up visit
3

Safety and Tolerability of Escalating Y90 Doses

To assess the safety and tolerability of escalating segmental Y90 doses (200- 500 Gy) using Bayesian optimal interval (BOIN) dose-escalation design under Data and Safety Monitoring Committee (DSMC) oversight

Time frame
From enrollment to end of post-treatment Y90 12 month follow up visit

Other outcomes

1

Pathologic Necrosis in Explanted Tumors

To evaluate complete pathological necrosis in explanted tumors from patients who undergo liver resection or transplantation

Time frame
From enrollment to end of post-treatment Y90 12 month follow-up visit
2

Early Imaging Biomarkers for Ablation Success

To identify novel early imaging biomarkers (Eovist hepatobiliary phase defects, extracellular volume mapping, perfusion changes) that may serve as surrogates for ablation success

Time frame
From enrollment to post-treatment Y90 12 month follow-up visit
