  • Histologically proven diagnosis of colorectal adenocarcinoma, with or without primary tumour in situ;
  • Liver-only disease at radiological exams involving less than 50% of liver volume;
  • Eastern Cooperative Oncology Group Performance Status (ECOG PS) ≤2;
  • Patients with partial response or stable disease according to RECIST 1.1 criteria deemed unresectable after 6-12 cycles of induction first-line chemotherapy;
Show all 21Show fewer
  • Life expectancy of at least 12 weeks;
  • Hematopoietic function: absolute neutrophil count ≥ 1,500/mm3; platelet count
  • ≥100,000/mm3; haemoglobin level ≥ 9 g/dL;

For this trial, women of childbearing potential are defined as all women after puberty, unless they are postmenopausal for at least 12 months, are surgically sterile, or are sexually inactive. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy. However, in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient;
  • Subjects and their partners must be willing to avoid pregnancy during the trial. Male subjects with female partners of childbearing potential and female subjects of childbearing potential must, therefore, be willing to use adequate contraception as outlined in Section 7.5 - Contraception, starting during study screening visit throughout the study period up to 180 days after the last dose of chemotherapy Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject;

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Progression-free survival (PFS) Rate

    PFS is defined as the time from study enrolment to the first documentation of objective disease progression or death due to any cause, whichever occurs first. PFS will be censored on the date of the last evaluable on study tumor assessment documenting absence of progressive disease for patients who are alive, on study and progression free at the time of the analysis.

    Measured: 36 months

Secondary outcomes (9)
  1. Overall Toxicity rate

    Overall Toxicity rate is defined as the percentage of patients, relative to the total of enrolled subjects, who receive 166Ho-TARE and at least one cycle of chemotherapy, experiencing any adverse event, according to National Cancer Institute Common Toxicity Criteria (version 5.0) during the study treatment.

    Measured: 36 months

  2. Grade 3/ Grade 4 Toxicity rate

    Grade 3/ Grade 4 Toxicity rate is defined as the percentage of patients, relative to the total of enrolled subjects, who receive 166Ho-TARE and at least one cycle of chemotherapy, experiencing a specific adverse event of severity grade 3/ grade 4, according to National Cancer Institute Common Toxicity Criteria (version 5.0) during the study treatment.

    Measured: 36 months

  3. Post-treatment Disease Control Rate (DCR)

    Post-treatment DCR, is defined as the percentage of patients, relative to the total of enrolled subjects, achieving a complete (CR), partial (PR) response or stable disease (SD), according to RECIST 1.1 criteria, during the study treatment. The determination of clinical response will be based on investigator reported measurements. Tumor re-assessment with CT scan will be repeated every 8- weeks.

    Measured: 36 months

  4. Progression free survival

    Progression free survival (PFS), is defined as the time from study enrolment to the first documentation of objective disease progression or death due to any cause, whichever occurs first. PFS will be censored on the date of the last evaluable on study tumor assessment documenting absence of progressive disease for patients who are alive, on study and progression free at the time of the analysis.

    Measured: 36 months

  5. Overall Survival

    Overall Survival (OS), is defined as the time from enrolment to death from any cause. For patients still alive at the time of analysis, the OS time will be censored on the last date the patients were known to be alive.

    Measured: 36 months

  6. Dose-response relationships

    Dose-response relationships are defined as the relationships between the tumor-absorbed doses calculated on post-treatment SPECT-CT (dependent variables) and the following independent variables: tumor response (SD, PR, CR according to RECIST CRITERIA v 1.1), progression free survival rate, and Overall Survival.

    Measured: 36 months

  7. Quality of Life (QoL) assessed using the EORTC QLQ-CR29 questionnaire

    The EORTC QLQ-CR29 is a patient-reported outcome measure to evaluate health-related quality of life among colorectal cancer patients in research and clinical practice.

    QoL assessed using the EORTC QLQ-CR29 questionnaire will be evaluate at specific time-points (baseline, tumor reassessment and disease progression) and will be assessed through descriptive summary statistics.

    Measured: 36 months

  8. Quality of Life (QoL) assessed using the EORTC QLQ-CR30 questionnaire

    The EORTC QLQ-CR30 is 30-item instrument designed to measure quality of life in all cancer patients.

    QoL assessed using the EORTC QLQ-CR30 questionnaire will be evaluate at specific time-points (baseline, tumor reassessment and disease progression) and will be assessed through descriptive summary statistics.

    Measured: 36 months

  9. Quality of Life (QoL) assessed using the EuroQol EQ-5D questionnaire

    The EuroQol EQ-5D comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems.

    QoL assessed using the EuroQol EQ-5D questionnaire will be evaluate at specific time-points (baseline, tumor reassessment and disease progression) and will be assessed through descriptive summary statistics.

    Measured: 36 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 166Holmium TARE, Cetuximab and Panitumumab in people with Colorectal Cancer Metastatic, run by Gruppo Oncologico del Nord-Ovest at 1 site in Italy.

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 21 inclusion and 12 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: stopped early, as of the sponsor's last update on 5 Jan 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 Italy. 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?

The study was stopped early (reason given: Medical devices (QuiremScout/QuiremSpheres) no longer available due to discontinuation of production by the manufacturer). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression-free survival (PFS) Rate (time frame: 36 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 5 Jan 2026.
