Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Tumor Absorbed Dose (Gy)
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.
Within 1 day following intervention
Secondary Outcomes (4)
Tumor-to-Normal Liver Ratio (T/N Ratio)
Within 1 day following intervention
Objective Response Rate (ORR) by RECIST 1.1
3 months and 6 months after radioembolization
Disease Control Rate (DCR) by RECIST 1.1
3 months and 6 months after radioembolization
Tumor Response by mRECIST for enhancing tumors
3 months and 6 months after radioembolization
Study Arms (1)
Single Group
EXPERIMENTALParticipants undergo Y-90 administration using both the TriNav Infusion System and a standard end hole microcatheter, with delivery sites randomized within the participant.
Interventions
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).
Eligibility Criteria
You may qualify if:
- Presence of multiple liver metastases
- Prior multidisciplinary clinical decision for treatment with radioembolization
- years of age or older
- ECOG less than or equal to 2
- Life expectancy \> 3 months
- Ability to understand and the willingness to provide written informed consent.
- At least 2 planned Y-90 delivery sites/vessels with the same target mean dose to tumor
- Angiosome for each delivery site has at least 1 measurable tumor per RECIST criteria
- At least 1 target tumor per delivery site is exclusively supplied by the angiosome of the delivery site.
- Vascular anatomy suitable for use with the TriNav Infusion System, including target vessel diameter 1.5-5 mm.
- The vessel level for each planned delivery site is no further distal than the segmental level.
You may not qualify if:
- Pregnant
- Breast-feeding
- Lung shunt fraction \> 20% or calculated lung dose \> 30 Gy
- Prior hepatic transarterial embolization in the hepatic lobe to be treated
