The purpose of the study is to determine if the type of catheter used in the mapping procedure prior to radioembolization improves the delivery of radioactivity to tumor(s) in participants with liver cancer.
The name of the devices involved in this study are:
- Pressure Enabled Drug Delivery (PEDD)/TriNav Infusion System
- Standard 2.4F microcatheter, not otherwise specified
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Liver Cancer Hepatocellular Carcinoma Metastatic Colorectal Cancer | Device: Standard microcatheter Device: PEDD device | Not Applicable |
This is a prospective, randomized, open-label, single-center, investigator-initiated study to determine if the type of catheter used to deliver the radiotracer in the mapping procedure improves the delivery of radioactive microspheres during radioembolization treatment for liver cancer.
Both catheters being used, the Pressure Enabled Drug Delivery (PEDD)/TriNav Infusion System and theStandard 2.4F microcatheter have been cleared for clinical use by the U.S. Food and Drug Administration.
Radioembolization for the treatment of liver tumors typically requires 2 separate procedures. The first procedure is called the mapping procedure. During the mapping procedure, the blood supply to the liver and tumor are evaluated with a type of x-ray called angiography. Once the optimal catheter position is determined for treatment, a "simulation" run is performed with the injection of a fluid that acts like the radiation that will be delivered to treat the tumors. This fluid is called a radiotracer. The study is looking to learn if the Pressure Enabled Drug Delivery device increases the ratio of radiotracer delivered to liver tumor tissue relative to normal liver tissue compared to a standard microcatheter. An improved delivery of radiotracer may indicate improved delivery of radioactive microspheres which may lead to improved tumor response rates and less liver toxicity
The research study procedures include assessments for eligibility, study treatment including evaluations, and follow-up visits.
Participants will undergo the study procedures in the normal course of their radioembolization procedure, with the addition of a second mapping procedure on the treatment day. Participants will be randomly assigned to one of two mapping procedures: Sequence A or Sequence B.
It is expected that about 10-20 people in total will take part in this research study.

Experimental: Sequence A: Standard microcatheter for Mapping #1 and PEDD device for Mapping #2.
Participants with either hepatocellular carcinoma (HCC) or colorectal liver metastases tumors receiving standard of care radioembolization treatment will be randomly assigned to undergo a routine mapping procedure first using a standard microcatheter 2-21 days before their radioembolization treatment day. Then on day of radioembolization treatment, an extra mapping procedure using the PEDD device catheter will be done just prior to the treatment.

- Radiotracer distribution [ Time Frame: Up to 2 years ]The primary endpoint of the study is radiotracer distribution, as measured by tumor to normal liver (T:N) ratio. Using SPECT/CT images collected subsequent to radiotracer delivery in mapping procedures, the volumetric tumor to normal liver (T:N) ratio of 99mTc-MAA distribution will be calculated using advanced imaging processing software, such as MIM SurePlan MRT. The T:N ratio of 99mTc-MAA delivered via the standard microcatheter will be compared to the PEDD device for each patient. The T:N ratio will be calculated for each tumor as well as in aggregate for the three largest tumors as described in Section 12.
- Mapping procedure comparison of Tumor to Normal (T:N) ratio between standard microcatheter and pressure-enabled delivery catheter [ Time Frame: Up to 2 years ]Compare the mapping procedure radiotracer T:N ratio to therapeutic microsphere T:N ratio for both the standard microcatheter and the PEDD device when both the radiotracer and therapeutic microspheres were delivered by the same catheter
- Technical success of radiotracer delivery as measured by ability to deliver radiotracer [ Time Frame: Up to 2 years ]Technical success of radiotracer delivery of each catheter, where success is defined as the satisfactory positioning and delivery of radiotracer.

- Known HCC or CLM that are not amenable to curative resection or thermal ablative techniques such as microwave ablation.
- Prior clinical decision for treatment by radioembolization.

- Age ≥18 years. Because there is limited data with respect to radioembolization in patients <18 years of age with respect to tumor dosimetry and associated adverse events participants <18 years of age, children are excluded from this study.

- Ability to understand and the willingness to sign a written informed consent document.
- Prior to study entry women of child-bearing potential must agree to not become pregnant, nurse a baby, or use any milk expressed for 2 weeks following radioembolization. Men must agree to not father a baby for 2 months after treatment with radioembolization (This is confirmed during the consenting process and documented when the patient signs the informed consent form. The effects of Yttrium-90 and radiation associated with the procedures, radiotracers, and subsequent imaging are known to have teratogenic effects on the developing human fetus. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother breastfeeding should be discontinued for the duration of study participation.)
