About this study

Official title: Phase II Study of AVELUMAB and CETUXIMAB and Modified FOLFOXIRI as Initial Therapy for RAS Wild-type Unresectable Metastatic Colorectal Cancer Patients

The aim of this study is to evaluate the efficacy of mFOLFOXIRI plus cetuximab and avelumab as first line treatment of patients with initially unresectable and previously untreated RAS wild-type metastatic colorectal cancer (mCRC), in terms of Progression-free Survival.

Read the detailed description

This is a prospective, open-label, multicentric phase II single-arm trial in which patients with initially unresectable and previously untreated RAS wild-type mCRC will receive induction treatment with mFOLFOXIRI plus cetuximab and avelumab up to 12 cycles followed by maintenance with 5-FU/LV plus cetuximab plus avelumab until disease progression, unacceptable toxicity or patient's refusal. The second- and subsequent lines of treatment will be at investigators' choice.

Being tested
5Fluorouracil, L-leucovorin, Irinotecan, Oxaliplatin, Cetuximab

What is being measured

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

  1. Progression-free Survival

    Progression-free survival is defined as the time from enrollment to the first documentation of objective disease progression or death due to any cause, whichever occurs first.

    Measured: 19 months

Secondary outcomes (7)

  1. Toxicity Rate

    Toxicity Rate is defined as the percentage of patients, relative to the total of enrolled subjects, experiencing a specific adverse event of grade 3/4, according to National Cancer Institute Common Toxicity Criteria (version 5.0), during the induction and the maintenance phases of treatment.

    Measured: 24 months

  2. Objective Response Rate

    Objective Response Rate is defined as the percentage of patients, relative to the total of enrolled subjects, achieving a complete (CR) or partial (PR) response, according to RECIST 1.1 criteria, during the induction and the maintenance phases of treatment. The determination of clinical response will be based on investigator reported measurements. Responses will be evaluated every 8 weeks.

    Measured: 19 months

  3. Immuno-related Objective Response Rate

    Immuno-related Objective Response Rate is defined as the percentage of patients, relative to the total of enrolled subjects, achieving a complete (CR) or partial (PR) response, according to immune-modified RECIST criteria, during the induction and the maintenance phases of treatment. The determination of clinical response will be based on investigator reported measurements. Responses will be evaluated every 8 weeks.

    Measured: 19 months

  4. Early Objective Response Rate

    Early Objective Response Rate is defined as the percentage of patients, relative to the total of the enrolled subjects, achieving a ≥ 20% decrease in the sum of diameters of RECIST target lesions at week 8 compared to baseline.

    Measured: up to 2 months from randomization

  5. Deepness of Response

    Deepness of Response is defined as the relative change in the sum of longest diameters of RECIST target lesions at the nadir, in the absence of new lesions or progression of non-target lesions, when compared with baseline.

    Measured: 19 months

  6. R0 Resection Rate

    R0 Resection Rate is defined as the percentage of patients, relative to the total of enrolled subjects, undergoing secondary R0 resection of metastases. Secondary R0 surgery is defined as microscopically margin free complete surgical removal of all residual disease, performed during treatment or after its completion, allowed by tumoral shrinkage and/or disappearance of one or more lesions.

    Measured: 19 months

  7. Overall survival

    Overall survival is defined as the time from registration to the date of death due to 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: 48 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 5Fluorouracil, L-leucovorin and Irinotecan in people with Metastatic Colorectal Cancer, 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 16 inclusion and 42 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: finished, as of the sponsor's last update on 9 Jan 2025. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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 (time frame: 19 months). 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 NCT04513951.

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 9 Jan 2025; AzTrials last refreshed its copy on 7 Nov 2026.
