Read more
Objective:
To see if treatment with HAIPs to deliver liver-directed FUDR and Dexamethasone chemotherapy in combination with PDS01ADC is effective for certain cancers.
Eligibility:
People aged 18 and older who have cancer of the bile ducts that is only in the liver, or colorectal cancer that has spread to the liver, or cancer of the adrenal glands that has spread to the liver, who are also receiving or planning to receive standard systemic chemotherapy for their disease.
Design:
Participants will be screened with:
Medical history
Physical exam
Blood tests
Pregnancy test (if needed)
Tumor biopsy (if needed)
Electrocardiogram
Computed tomography (CT) scans
Participants will have an abdominal operation. A catheter will be placed into an artery that feeds blood to the liver. The catheter will then be attached to the HAIP. The HAIP will lay under the skin on the left side of the abdomen.
All participants will have liver-directed FUDR and Dexamethasone chemotherapy drugs or heparin with saline infused into the HAIP every 2 weeks. PDS01ADC will be injected under the skin every 4 weeks. They will receive this treatment until their cancer gets worse or they have bad side effects.
Participants will also receive standard systemic chemotherapy for their disease, assigned based on diagnosis, through an IV by their medical oncologist (at NIH or by a local provider) every 2 weeks.
Participants will have 2 study visits at NIH each month. They will have CT scans every 8 weeks. At visits, they will repeat some screening tests.
Participants will have a follow-up visit 1 month after treatment ends. Then they will be contacted every 6 months for 5 years.
Read the detailed description
Background:
Regional chemotherapy for hepatic malignancies takes advantage of the fact that tumors are perfused almost exclusively by the hepatic artery and, that the agent used (Floxuridine, FUDR) has a 95% first-pass metabolism by the liver.
Early clinical trials performed during the 1970's and 1980's demonstrated impressive response rates that led to the adoption of hepatic artery infusion pump chemotherapy (HAIP) at select centers; however, little has changed in the ensuing decades with respect to regional
therapy for the liver, although there has been continued and even renewed interest.
Dose reductions of FUDR are common after several treatments, which has limited both the magnitude and duration of treatment responses in many cases.
We posit that the logical and much-needed "next step" in regional therapy is to take advantage of the FUDR-induced tumor necrosis with an agent able to activate local tumor immunity for a synergistic effect.
PDS01ADC is an immunocytokine composed of two IL-12 heterodimers, each fused to the H-chain of the NHS76 antibody. The NHS76 IgG1 antibody has affinity for both single- and double-stranded DNA (dsDNA), and targets regions of tumor necrosis where DNA has become exposed. PDS01ADC targets necrotic areas of the tumor and activates immune cells in the tumor microenvironment to induce a Th1 polarization of lymphocytes and the release of IFN-gamma. IFN-gamma in turn induces a host of immunomodulatory effects that contribute to robust antitumor responses that are localized within the tumor microenvironment, with no systemic distribution or exposure to IL-12.
Data from a recent Phase I study demonstrate that subcutaneous administration of PDS01ADC is safe and a MTD has been determined. Moreover, preclinical models indicate that PDS01ADC synergizes with therapies able to effectively induce tumor necrosis, which may also minimize toxicity by limiting off-target exposure.
Objective:

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
DexamethasoneDrug
HAIP FUDR and Dexamethasone treatment on D1 of every cycle. Dexamethasone: (1 mg/day X pump volume / pump flow rate)
PDS01ADCDrug
PDS01ADC will be administered by subcutaneous injection on Day 15 of every cycle. Cycle 1 at 12 mcg/kg; Cycle 2 reduced to 8 mcg/kg with the addition of systemic chemotherapy, to continue for further cycles. Note: any dose reduction in FUDR = 50% due to liver enzyme elevations means that the dose of PDS01ADC will be reduced to 4 mcg/kg.
Intera 3000 Hepatic Artery Infusion Pump (HAIP)Device
Intera 3000 HAIP will be filled with mixture of Floxuridine and Dexamethasone in 25,000 units heparin/saline (Heparin + 0.9% Sodium Chloride) on Day 1; Days 1-14 of every cycle pump will perfuse drugs to liver. On Day 15 of each cycle, the pump will be emptied and filled with 30,000 units heparin/saline (Heparin + 0.9% Sodium Chloride); Days 15-28 of every cycle will perfuse heparin/saline to liver.
FloxuridineDrug
HAIP FUDR and Dexamethasone treatment on D1 of every cycle. Floxuridine: (0.12 mg/kg x ideal average body weight in kg X 30 mL [pump volume] / Pump Flow Rate)

What is being measured
The primary outcome is the main question the study is designed to answer.
Determine overall response rates
Simon optimal two-stage Phase II trial design will be used to determine overall response using RECIST criteria. The clinical response rate (CR+PR) will be determined and reported along with a 95% confidence interval, separately by cohort.
Measured: baseline, every 8 weeks while on treatment, and 4-8 weeks following initial documentation of objective response; an additional scan is performed at Week 12.
Secondary outcomes (4)
Determine overall survival (OS)
CT will be used for response criteria. Overall survival (OS) probability will be determined using Kaplan-Meier estimates for all participants, separately by cohort; the median OS will be reported along with a 95% confidence interval.
Measured: date of enrollment until death from any cause, or after 5 years off treatment
Determine extra-hepatic progression-free survival (PFS)
CT will be used for response criteria. Extra-hepatic progression-free survival (PFS) probability will be determined using Kaplan-Meier estimates for all participants, separately by cohort; the median PFS will be reported along with a 95% confidence interval.
Measured: date of operation to date of first observation of progressive disease within the liver or death, or after 5 years off treatment whichever comes first
Evaluate safety of PDS01ADC in combination with HAIP therapy
Safety will be assessed by analyzing the type, grade and frequency. Toxicities by grade and per participant will be determined and reported separately by disease cohort.
Measured: on-going from treatment start through end of treatment visit
Determine hepatic progression-free survival (PFS)
CT will be used for response criteria. Hepatic progression-free survival (PFS) probability will be determined using Kaplan-Meier estimates for all participants, separately by cohort; the median PFS will be reported along with a 95% confidence interval.
Measured: date of operation to date of first observation of progressive disease within the liver or death, or after 5 years off treatment whichever comes first

Interventions
| Intervention | Type | Arms |
|---|---|---|
| DexamethasoneHAIP FUDR and Dexamethasone treatment on D1 of every cycle. Dexamethasone: (1 mg/day X pump volume / pump flow rate) | Drug | 1/ HAIP +PDS01ADC+FOLFOX or FOLFORI, 2/ HAIP +PDS01ADC+GemOx or FOLFOX, 3/ HAIP +PDS01ADC+GemOx |
| PDS01ADCPDS01ADC will be administered by subcutaneous injection on Day 15 of every cycle. Cycle 1 at 12 mcg/kg; Cycle 2 reduced to 8 mcg/kg with the addition of systemic chemotherapy, to continue for further cycles. Note: any dose reduction in FUDR = 50% due to liver enzyme elevations means that the dose of PDS01ADC will be reduced to 4 mcg/kg. | Drug | 1/ HAIP +PDS01ADC+FOLFOX or FOLFORI, 2/ HAIP +PDS01ADC+GemOx or FOLFOX, 3/ HAIP +PDS01ADC+GemOx |
| Intera 3000 Hepatic Artery Infusion Pump (HAIP)Intera 3000 HAIP will be filled with mixture of Floxuridine and Dexamethasone in 25,000 units heparin/saline (Heparin + 0.9% Sodium Chloride) on Day 1; Days 1-14 of every cycle pump will perfuse drugs to liver. On Day 15 of each cycle, the pump will be emptied and filled with 30,000 units heparin/saline (Heparin + 0.9% Sodium Chloride); Days 15-28 of every cycle will perfuse heparin/saline to liver. | Device | 1/ HAIP +PDS01ADC+FOLFOX or FOLFORI, 2/ HAIP +PDS01ADC+GemOx or FOLFOX, 3/ HAIP +PDS01ADC+GemOx |
| FloxuridineHAIP FUDR and Dexamethasone treatment on D1 of every cycle. Floxuridine: (0.12 mg/kg x ideal average body weight in kg X 30 mL [pump volume] / Pump Flow Rate) | Drug | 1/ HAIP +PDS01ADC+FOLFOX or FOLFORI, 2/ HAIP +PDS01ADC+GemOx or FOLFOX, 3/ HAIP +PDS01ADC+GemOx |
Primary outcome
Determine overall response rates
Time frame: baseline, every 8 weeks while on treatment, and 4-8 weeks following initial documentation of objective response; an additional scan is performed at Week 12.
Simon optimal two-stage Phase II trial design will be used to determine overall response using RECIST criteria. The clinical response rate (CR+PR) will be determined and reported along with a 95% confidence interval, separately by cohort.
4 secondary outcomes
Determine overall survival (OS)
Time frame: date of enrollment until death from any cause, or after 5 years off treatment
Determine extra-hepatic progression-free survival (PFS)
Time frame: date of operation to date of first observation of progressive disease within the liver or death, or after 5 years off treatment whichever comes first
Evaluate safety of PDS01ADC in combination with HAIP therapy
Time frame: on-going from treatment start through end of treatment visit
Determine hepatic progression-free survival (PFS)
Time frame: date of operation to date of first observation of progressive disease within the liver or death, or after 5 years off treatment whichever comes first

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Dexamethasone, PDS01ADC and Intera 3000 Hepatic Artery Infusion Pump (HAIP) in people with Metastatic Colorectal Cancer (Mcrc) and Intrahepatic Cholangiocarcinoma (Icc), run by National Cancer Institute (NCI) at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 55 inclusion and 34 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 16 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?
Determine overall response rates (time frame: baseline, every 8 weeks while on treatment, and 4-8 weeks following initial documentation of objective response; an additional scan is performed at Week 12.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05286814, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Oct 2026.
