What You Need to Know Before You Apply

What is the purpose of this trial?

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

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, you cannot have had chemotherapy or radiotherapy within 4 to 6 weeks before joining the study.

How is the Pressure-enabled Drug Delivery (PEDD) treatment for liver cancer different from other treatments?

The PEDD treatment for liver cancer is unique because it uses a specialized microcatheter system to deliver drugs directly to the liver with enhanced precision, potentially improving drug distribution and reducing side effects compared to standard methods. ^{1 2 3 4 5}

Are You a Good Fit for This Trial?

Adults with liver cancer or colorectal metastases to the liver, who can't have surgery or thermal ablation. They should be in relatively good health (ECOG <2), with a life expectancy over 16 weeks and adequate organ function. Participants must not be pregnant, nursing, or planning to conceive soon. Those with stable extrahepatic disease may qualify.

Inclusion Criteria

My organs and bone marrow are working well.

I can do most of my daily activities by myself.

Exclusion Criteria

I have had radiation or specific artery treatments to my liver before.

More than half of my liver is affected by cancer.

I have received treatment for a condition affecting the Ampulla of Vater.

What Are the Treatments Tested in This Trial?

Interventions

• PEDD device
• Standard microcatheter

Trial Overview The study is testing whether using a Pressure Enabled Drug Delivery (PEDD) device during mapping for radioembolization improves treatment delivery to liver tumors compared to a standard microcatheter.

How Is the Trial Designed?

Group I: Sequence B: PEDD device for Mapping #1 and standard microcatheter for Mapping #2. Experimental Treatment 2 Interventions

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 the PEDD device catheter 2-21 days before their radioembolization treatment day. Then on day of radioembolization treatment, an extra mapping procedure using a standard microcatheter will be done just prior to the treatment.

Group II: Sequence A: Standard microcatheter for Mapping #1 and PEDD device for Mapping #2. Experimental Treatment 2 Interventions

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.

PEDD device is already approved in United States for the following indications:

Approved in United States as TriNav Infusion System for:

• Liver cancer

Published Research Related to This Trial

The coaxial reservoir system with a non-braided microcatheter was successfully implanted in 100% of the 80 patients, demonstrating its efficacy for hepatic arterial infusion chemotherapy.

While the system is generally safe, there were some complications, including a 10% rate of hepatic arterial occlusion, indicating that while effective, careful monitoring is necessary during treatment.

A totally implanted drug delivery system for hepatic arterial chemotherapy was successfully evaluated in 13 patients, showing reliable performance with stable flow rates and excellent patient acceptance over a median treatment duration of 6 months.

The system led to partial tumor regressions in 11 out of 13 patients, indicating its efficacy in delivering chemotherapy directly to liver tumors, while allowing patients to maintain normal daily activities.

Antireflux microcatheters (ARMs) are a new type of microcatheter that can enhance liver-directed therapies like selective internal radiotherapy (SIRT) and trans-arterial chemoembolization (TACE) by reducing particle reflux and improving drug delivery to tumors.

Using ARMs may lead to better particle distribution and embolization efficiency, potentially resulting in improved disease response for patients with liver cancers, particularly hepatocellular carcinoma.

A new implantable port design allows for easy insertion of a microcatheter, enabling repeated transarterial chemoembolization (TACE) and hepatic arterial infusion chemotherapy (HAIC) for advanced liver cancer.

In both in vitro and in vivo studies, the port demonstrated successful catheterization and repeated selective embolization in a pig model, indicating its potential effectiveness for ongoing cancer treatment.

A new model for hepatic arterial chemotherapy using large dogs and an implantable infusion pump allows for over 90% perfusion of the liver, making it a reliable method for studying liver-targeted treatments.

The implantation of the pump does not cause acute liver damage or affect the dogs' mobility, indicating its safety for use in preclinical studies of chemotherapeutic agents.
