Study summary

A total of 116 patients who meet the inclusion criteria and are chemotherapy-naïve for their metastatic disease, will be randomly assigned to either the treatment group (DEBIRI plus systemic chemotherapy) or the control group (systemic chemotherapy alone).

After 4 cycles of chemotherapy and 2 cycles of DEBIRI, patient reassessment to evaluate treatment response, based on RECIST criteria, will be performed using MRI or CT scan within 1-3 months of treatment initiation.

The feasibility of secondary tumor resection, as primary endpoint, will be reassessed at a three-month follow-up multidisciplinary team (MDT) meeting, guided by established clinical guidelines.

Read the detailed description

Upon acquiring ethical approval, patients with histologically proven, unresectable or borderline resectable liver metastases from colorectal origin who are referred to the hepatobiliary clinic between September 2024 and September 2026 will be enrolled to the study. Informed consent will be obtained for their participation prior to enrollment.

A total of 116 patients who are chemotherapy-naïve for their metastatic disease, will be randomly assigned to either the treatment group or the control group.

With the aim of controlling major confounding factors, Stratified randomization will be performed based on synchronous/metachronous liver metastases and unresectable/borderline resectable status.

Targeted therapy administration for each treatment group in based on oncologist's decision and will be tailored to the tumor's biological characteristics and the patient's clinical status. Ultimately, patients will be categorized into one of the two following treatment groups:

Group 1: DEBIRI+ standard systemic chemotherapy ± Targeted therapy Group 2: Standard systemic chemotherapy ± Targeted therapy The Tumor characteristics, including the number, size, and anatomical location, as well as the presence or absence of extrahepatic metastases, will be assessed based on initial imaging (MRI).

The treatment protocol is defined as the administration of a chemotherapy regimen on days 0 and 14, followed by DEBIRI on days 7 and 21. Each patient of the treatment arm will receive at least two doses of DEBIRI unless treatment-limiting adverse events occur.

After 4 cycles of chemotherapy and 2 cycles of DEBIRI, patient reassessment to evaluate treatment response will be performed using MRI or CT scan within 1-3 months of treatment initiation. All imagings will be reviewed by 2 radiologists who are blinded to clinical information regarding treatment arm. Treatment response will be determined using RECIST criteria.

Conversion to resectability, as primary endpoint, will be evaluated at a three-month follow-up multidisciplinary team (MDT) meeting, guided by established clinical guidelines.

Secondary endpoints of the study will encompass evaluation of treatment tolerability and adverse event rate, alongside analyzing progression-free survival and overall survival.

Inclusion criteria

  • unresectable/borderline resectable colorectal cancer liver , chemotherapy-naïve for metastatic disease, (ECOG) performance status of 2 or less adequate hematologic, hepatic, and renal function ( ≥ 1.5 × 10\^9/L, ≥ 75 ×10\^9/L, ≤ 1.3, Total ≤ 2.0 mg/dL, and alanine aminotransferase ≤ 5 × the (ULN), Albumin ≥ 2.5 g/dL, Creatinine ≤ 2.0 mg/dL)

Exclusion criteria

Exclusion Criteria:

Terms in these criteria, in plain language(11)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Study arms

  • Experimental
    DEBIRI+ Chemotherapy +/- Targeted therapy

    Patients will receive systemic chemotherapy on day 0 and 14 and DEBIRI on day 7 and 21.

    Drug: Drug-Eluting Embolic Bead

  • Active comparator
    Chemotherapy +/- Targeted therapy

    Patients will receive 4 cycles of systemic chemotherapy.

    Drug: Chemotherapy drug

Interventions

  • DrugDrug-Eluting Embolic Bead

    A minimum of 2 sessions of DEBIRI treatment and 2-4 cycles of systemic chemotherapy are administered (based on tumor size, bilobar or unilobar involvement of the liver, treatment response rate, treatment tolerance, occurrence of side effects, and liver function). Prior to performing DEBIRI, initial angiography is done via the femoral or axillary artery to determine the anatomy of the right and left hepatic arteries as well as the arteries supplying the tumor. Subsequently, a vial of irinotecan (100 mg) eluted with a vial of beads(hepaSphere 25mg) is injected into the blood vessels feeding the tumor. The intervention will be repeated to deliver 200 mg of irinotecan intravascularly to the liver mass. A 14-day interval between the procedures is established to minimize side effects. Targeted therapy administration for each treatment group based on oncologist's decision and will be tailored to the tumor characteristics and the patient's clinical status as explained in control arm.

    Also known as: Irinotecan-loaded drug-eluting beads (DEBIRI) plus systemic chemotherapy +/- targeted therapy

  • DrugChemotherapy drug

    Control group will receive 2-4 cycles of systemic chemotherapy based on functional status of the patient, adverse event rate and treatment tolerance, tumor size and characteristics. Targeted therapy administration for each treatment group in based on oncologist's decision and will be tailored to the tumor characteristics and the patient's clinical status (e.g., administration of Pembrolizumab for patients with high rosatellite instability (MSI-H) or Bevacizumab for tumors harboring KRAS mutations). Due to the targeted nature of these therapies, they can not be administered to all participants of the trial, while It is not ethically justifiable to withhold targeted therapies from patients who are candidates for these treatments based on their tumor characteristics and deprive them of potentially life-extending options.

    Also known as: Systemic chemotherapy +/- targeted therapy

This study also gives Pembrolizumab. No intervention listed here names it: that was found by reading the record.

What researchers measure

Primary outcomes

  1. Conversion to resectability: The proportion of patients who were initially deemed unresectable but, after undergoing specific intervention (Based on study arm) are reassessed for tumor shrinkage and found to be candidates for surgical resection.

    The feasibility of secondary tumor resection after receiving treatment, based on follow up imaging and tumor downsizing, will be discussed in multidisciplinary meeting (including surgeons, radiologists and oncologists).

    Time frame: within 3 months after treatment initiation

Secondary outcomes

  1. Adverse event rate

    Unfavorable and unintended signs and symptoms associated with the treatment.

    Time frame: Within 1 year of treatment administration

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 23, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
