DEBIRI Plus Chemotherapy vs. Chemotherapy Alone in Colorectal Cancer Liver Metastases

NCT ID: NCT06555003

Last Updated: 2025-04-23

Basic Information

• Recruitment Status: RECRUITING
• Clinical Phase: PHASE3
• Total Enrollment: 116 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2025-01-20
• Study Completion Date: 2027-12-31

Brief 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.

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.

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: SINGLE

Study Groups

DEBIRI+ Chemotherapy +/- Targeted therapy

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

Group Type: EXPERIMENTAL

Drug-Eluting Embolic Bead

Intervention Type: DRUG

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.

Chemotherapy +/- Targeted therapy

Patients will receive 4 cycles of systemic chemotherapy.

Group Type: ACTIVE_COMPARATOR

Chemotherapy drug

Intervention Type: 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.
