End Hole vs. Pressure-Modulated Delivery of Y-90 Resin Microspheres to Liver Metastases.
Pressure-Enabled Selective SIR-Sphere Uptake for Radiation Efficacy (PRESSURE): A Prospective Randomized Clinical Trial of End Hole vs. Pressure-Modulated Delivery of Y-90 Resin Microspheres to Liver Metastases.
Patients with liver metastases undergoing planning arteriography for Y-90 administration by interventional radiology will be screened for study enrollment. If there are at least 2 planned delivery sites with the same target mean dose to tumor and at least 1 tumor in each angiosome that is measurable by RECIST criteria, the patient is potentially eligible for this study (see full inclusion and exclusion criteria). On the day of Y-90 administration, one delivery site will be randomized to a standard end hole microcatheter while the other delivery site will be assigned to the TriNav Infusion System.
A standard of care post-Y-90 PET/CT will be performed and dosimetry analysis will be conducted. The patient will also undergo a standard of care MRI 3 months and 6 months following Y-90 administration and disease response will be graded according to RECIST/mRECIST criteria.

Deltakergruppe / Arm |
Intervensjon / Behandling |
|---|---|
|
Eksperimentell: Single Group
Participants undergo Y-90 administration using both the TriNav Infusion System and a standard end hole microcatheter, with delivery sites randomized within the participant.
|
The Y-90 dose to be delivered by the TriNav Infusion System will be determined and recorded by the Investigator or Sub-Investigator, calculated using partition-based dosimetry software (i.e.
MIM SurePlan or Simplicit90y)
The comparator is a standard end hole microcatheter, defined as any commercially available microcatheter utilizing a single end hole without balloon occlusion or other tip modifications.
The Y-90 dose delivered by the standard end hole microcatheter will be determined and recorded by the Investigator or Sub-Investigator and calculated using partition-based dosimetry software (e.g., MIM SurePlan or Simplicit90Y).

Tumor Absorbed Dose (Gy)
Tidsramme: Within 1 day following intervention
|
Tumor absorbed dose (Gy) measured using post-radioembolization ^90Y PET/CT and Simplicit90Y dosimetry analysis software.
The endpoint will compare the absorbed dose delivered to tumors following Y-90 administration using the TriNav Infusion System versus a standard end-hole microcatheter.

Tumor-to-Normal Liver Ratio (T/N Ratio)
Tidsramme: Within 1 day following intervention
|
T/N ratio measured on post-radioembolization ^90Y PET/CT using Simplicit90Y dosimetry analysis software.
This endpoint evaluates preferential microsphere deposition within tumor relative to normal liver tissue and compares results between treatment groups.

Objective Response Rate (ORR) by RECIST 1.1
Tidsramme: 3 months and 6 months after radioembolization

Tumor Response by mRECIST for enhancing tumors
Tidsramme: 3 months and 6 months after radioembolization
|
For tumors demonstrating arterial enhancement on pre-treatment imaging, treatment response will be assessed using mRECIST criteria on contrast-enhanced MRI of the abdomen at 3 and 6 months following radioembolization.
