Trial summary

This study evaluates the Impact of DihydroPyrimidine Dehydrogenase (DPD) activity on the efficacy of Capecitabine in patients with metastatic breast cancer. The DPD phenotype before the initiation of treatment will be assess and then the patient will be follow up during the treatment with Capecitabine up to 24 month. Read more about this study

What is being measured

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

  1. 6 months objective response rate

    The primary endpoint will be the 6-month objective response to treatment measured using the RECIST 1.1 scale, or PERCIST 1.0. The objective response is defined as the aggregation of the complete + partial response against stabilization + progression.

    The distribution of the objective response rate with respect to the value of individual lymphocyte DPD activity before treatment will be examined. This analysis will consist in comparing the objective response rate between patients with a proficient DPD phenotype, measured by lymphocyte DPD activity (> at the 3rd quartile, ie 25% of the initial population) and non-deficient patients with DPD (including phenotype). between the 13th and 75th percentiles of the initial population).

    Measured: 6 months

Secondary outcomes (4)
  1. 6 months objective response in proficient DPD phenotype

    RECIST 1.1 or PERCIST 1.0 criteria

    Measured: 6 months

  2. Correlation between the level of lymphocyte DPD activity and uracil dosage

    Measured: 1 month

  3. Progression-free survival

    Measured: 24 months

  4. Capecitabine Toxicity using CTCAE v 5.0

    Measured: 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing DPD activity assessment and Capecitabine in people with Breast Neoplasm Malignant Female, run by Centre Antoine Lacassagne at 5 sites in 2 countries.

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 7 inclusion and 5 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: under way, not looking for participants, as of the sponsor's last update on 2 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in France, Monaco. 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?

This study is still under way. Results are not available in the source record yet.

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?

6 months objective response rate (time frame: 6 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 2 Jun 2026.
