What is being measured

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

  1. Progression-free survival rate at 35 months

    35-month PFSR defined as the number of patients, who at 35 months after randomization, have not had second or first disease progression nor died (due to any cause), over the total number of evaluable patients.

    Measured: 35 months after date of randomization

Secondary outcomes (13)
  1. overall survival rate at 35 months

    35-month OSR defined as the number of patients who at 35 months after randomization have not died over the total number of evaluable patients.

    Measured: 35 months after date of randomization

  2. overall survival

    OS defined as the time from randomization to the date of death (due to any cause), with patients alive or lost to follow-up at the analysis data cut-off date censored at their last contact date.

    Measured: Baseline through the end of the study (up 72 months)

  3. progression-free from randomization to second progression or death

    Total PFS defined as the time from randomization to second disease progression (i.e. progression during the second-line treatment) or death (due to any cause).

    Measured: Baseline through the end of the study (up 72 months)

  4. progression-free survival in first-line treatment and in second-line treatment

    PFS in first-line treatment defined as the time from randomization to disease progression or death (due to any cause) during first-line treatment. PFS in second-line treatment defined as the time from the date of second-line treatment initiation to disease progression or death (due to any cause) during secondline treatment.

    Measured: Baseline through the end of the study (up 72 months)

  5. time to first-line treatment failure and to second-line treatment failure

    Time to first-line treatment failure defined as the time form randomization to disease progression, death (due to any cause) or discontinuation due to toxicity during first-line treatment. Time to second-line treatment failure defined as the time from the date of second-line treatment initiation to disease progression, death (due to any cause) or discontinuation due to toxicity during second-line treatment.

    Measured: 72 months

  6. objective response rate

    Proportion of patients with an objective response (complete or partial response) per Response Evaluation Criteria in Solid Tumours (RECIST) 1.1 criteria in first-line treatment and in second-line treatment.

    Measured: Baseline through the end of the study (up 72 months)

  7. proportion of patients with Early Tumour Shrinkage

    Proportion of patients with ETS in first-line treatment and in second-line treatment. ETS will be defined as a reduction in tumour size ≥30% (RECIST 1.1 criteria) at the first evaluation (i.e. week 12)

    Measured: Baseline through the end of the study (up 72 months)

  8. Depth of Response

    DpR measured as the maximum decrease in target measurement (RECIST 1.1 criteria) during the complete course of evaluation in first-line treatment and in second-line treatment.

    Measured: Baseline through the end of the study (up 72 months)

  9. disease control rate

    Proportion of patients with disease control (complete, partial response or stable disease) in first-line treatment and in second-line treatment.

    Measured: Baseline through the end of the study (up 72 months)

  10. duration of disease control

    Duration of disease control defined as time from first confirmed disease control to disease progression per RECIST 1.1 criteria or death (due to any cause) in first-line treatment and in second-line treatment. For patients with disease control who have not progressed or died at last observation, duration of disease control will be censored at their last evaluable disease assessment date.

    Measured: Baseline through the end of the study (up 72 months)

  11. duration of response

    Duration of response defined as time from first confirmed objective response to disease progression per RECIST 1.1 criteria or death (due to any cause) in first-line treatment and in second-line treatment. For patients with response who have not progressed or died at last observation, duration of response will be censored at their last evaluable disease assessment date.

    Measured: Baseline through the end of the study (up 72 months)

  12. time to response

    Time to response in first-line treatment defined as the time from randomization to the date of first confirmed objective response per RECIST 1.1 criteria during first-line treatment.

    Time to response in second-line treatment defined as the time from the date of second-line treatment initiation to the date of first confirmed objective response per RECIST 1.1 criteria during second-line treatment.

    Measured: Baseline through the end of the study (up 72 months)

  13. Incidence and severity of AEs CTCAE v4.03 criteria

    Safety assessment will consist of monitoring adverse events (AEs), including AEs of special interest, serious AEs (SAEs) and laboratory safety parameters. AEs will be graded according to National Cancer Institute - Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 4.03.

    Measured: Baseline through the end of the study (up 72 months)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing FOLFOX regimen, Panitumumab and Bevacizumab in people with Colorectal Cancer, run by Spanish Cooperative Group for the Treatment of Digestive Tumours (TTD) at 1 site in Spain.

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 11 inclusion and 28 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: status not confirmed, as of the sponsor's last update on 21 Oct 2024. 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 Spain. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

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 rate at 35 months (time frame: 35 months after date of randomization). 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 21 Oct 2024.
