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.

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.

Interventions

• Device
  The TriNav Infusion Systems

  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)

• Device
  Standard End Hole Microcatheter

  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).
