About this study
Official title: Randomized Control Study of Capecitabine vs. S-1 in Unresectable or Recurrent Breast Cancer Patients
To investigate and compare the efficacy and safety of S-1 vs. Capecitabine as primary chemotherapy in patients with inoperable or recurrent breast cancer.
Read the detailed description
The incidence of breast cancer is increasing in Japan: 33,676 women were diagnosed with breast cancer in 2001, making it the leading cause of cancer among women since 1995. Statistical database in Exel format/outline of health welfare statistics from the Ministry of Labor, Health, and Welfare show that the number of deaths from breast cancer was 9,806 in 2003. Because the ten-year survival rate is about ninety percent in Stages 0 and I breast cancer patients, detection and treatment at an earlier stage can lead to higher survival rates. However, the recurrence rate increases as the disease progresses. In addition, about thirty percent of all breast cancer patients are believed to have recurrent disease. Thus, developing treatments against recurrence may be an important task.
The Guideline for Breast Cancer Treatment, 2004 version, recommends chemotherapy, including anthracyclines or taxanes as a first-line chemotherapy for metastatic or recurrent (grade B recommendation) breast cancer. In a second-line therapy recommended for metastatic or recurrent diseases, the Guideline reports that a combination of capecitabine, a 5Fu derivative (an oral chemotherapy of pyrimidine fluorides approved in 2003) with docetaxel is superior to docetaxel alone for improving survival. This regimen is recommended for patients with cardiac malfunction who cannot be treated with anthracyclines (grade B recommendation). However, data are lacking to support capecitabine as a standard regimen as a second-line therapy; its efficacy needs verification and further study. Accordingly, this study is designed to investigate the efficacy and safety of S-1 alone, an oral pyrimidine fluoride, to which an indication of "inoperable or recurrent breast cancer" was added, as a first-line therapy in patients with inoperable or recurrent breast cancer by comparing it with Capecitabine alone, which is already approved of the same indication.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Capecitabine and S-1 in people with Breast Neoplasms, run by Japan Breast Cancer Research Network at 8 sites in Japan.
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 15 inclusion and 14 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 29 May 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 8 sites in Japan. 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?
Yes. Results are posted in the registry (first posted 29 May 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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: The follow up period will be two years after the last dose has been administered.). 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 29 May 2015; AzTrials last refreshed its copy on 7 Nov 2026.
