A Phase 2 interventional study of DPD activity assessment and Capecitabine in Breast Neoplasm Malignant Female, sponsored by Centre Antoine Lacassagne. Active, not recruiting at 5 sites in 2 countries. Open to female participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-06-02.

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.
14,825 studies on the registry are indexed under Breast Neoplasms; 3,319 are open to participants now.
This study's planned enrollment of 155 is above the median of 72 across 10,896 interventional studies indexed under Breast Neoplasms.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
HER2 is a protein, made from the ERBB2 gene, that drives the growth of some cancers. A study may look for a level of the protein, extra copies of the gene, or a particular change in it.
In breast cancer, protein tests are read as HER2-positive, HER2-low or HER2-negative; other cancers use their own rules. Check which test result the study requires.
The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.
“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Cancer that has spread to the leptomeninges, the thin layers covering the brain and spinal cord, and the fluid between them. It is not the same as brain metastases.
Criteria often treat it separately, and many studies leave it out even where treated brain metastases are allowed.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

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).

Started Jul 2020 (actual). Primary completion is estimated for Sep 2026, 74 months after the start.
Of 1,070 non-industry phase 2 interventional studies under Breast Neoplasms, half reached primary completion within 56 months of starting (the median), counting those still running; a quarter within 34 and three quarters within 87. This study's planned 74 months is above that.
Counting every sponsor, half of 1,302 studies reached it within 51 months; a quarter within 30 and three quarters within 82.
