Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Histologically- or cytologically-proven diagnosis of breast adenocarcinoma that is not amenable to surgery, radiation, or combined modality therapy with curative intent
  • Measurable disease as per RECIST. Measurable lesions that have been previously irradiated will not be considered target lesions unless increase in size has been observed following completion of radiation therapy.
  • Prior treatment with an anthracycline and a taxane in the neoadjuvant, adjuvant or metastatic disease settings.

Exclusion criteria

  • Histology of inflammatory carcinoma with no other measurable disease. Patients with histology of inflammatory carcinoma are allowed on study if they have measurable disease.
  • Brain metastases, spinal cord compression, or carcinomatous meningitis, or leptomeningeal disease.
  • Prior treatment with 5-fluorouracil (5-FU) and 5-FU derivatives such as Furtulon (5'-DFUR), Futraful/ Sunfural (tegafur), UFT/UFT-E (tegafur/uracil), TS-1 (tegafur/gimeracil/oteracil) or Mifurol (carmofur) in metastatic disease setting

Primary outcomes

  1. Number of Participants With Objective Response Based on Data Review Committee's Assessment

    Time frame: Day 1 of Cycle 2, every 6 weeks after Cycle 2, and at the end of Cycle 8.

    Number of participants with objective response based on assessment of confirmed complete response (CR) or confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors version 1.0 (RECIST). CR is defined as disappearance of all target and non-target lesions. PR is defined as ≥30% decrease in sum of the longest dimensions (LDs) of the target lesions taking as reference the baseline sum LD according to RECIST. Confirmed responses are those that persist on repeat evaluation ≥4 weeks after initial documentation of response.

Secondary outcomes

    Time frame: Day 1 of Cycle 2, every 6 weeks after Cycle 2, and at the end of study.

PR is defined as ≥30% decrease in sum of the LDs of the target lesions taking as reference the baseline sum LD according to RECIST. Confirmed responses are those that persist on repeat evaluation ≥4 weeks after initial documentation of response.

  2. Number of Participants With Clinical Benefit Response (CBR) Based on Data Review Committee's Assessment

    Number of participants with confirmed CR, PR or stable disease (SD) for at least 24 weeks on study according to RECIST. CR is defined as disappearance of all target and non-target lesions. PR is defined as ≥30% decrease in sum of the LDs of the target lesions taking as a reference the baseline sum LD according to RECIST. SD is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease taking as reference smallest sum of LDs since treatment started.

  3. Number of Subjects With CBR Based on Investigator's Assessment

    Time frame: Day 1 of Cycle 2, every 6 weeks after Cycle 2, and at the end of study.

    Number of participants with confirmed CR, PR or SD for at least 24 weeks on study according to RECIST. CR is defined as disappearance of all target and non-target lesions.

    Time frame: Day 1 of Cycle 2, every 6 weeks after Cycle 2, and at the end of Cycle 8. Up to 28 days after the last administration of the study drug.

    Based on Data Review Committee's Assessment. DR is defined as the time from the first documentation of objective tumor response (confirmed CR or PR) to the first documentation of disease progression or to death due to cancer, whichever occurred first. CR is defined as disappearance of all target and non-target lesions. PR is defined as ≥30% decrease in sum of the LDs of the target lesions taking as reference the baseline sum LD according to RECIST. Confirmed responses are those that persist on repeat evaluation ≥4 weeks after initial documentation of response.

  7. Time to Objective Tumor Response (TTR)

    Time frame: Day 1 of Cycle 2, every 6 weeks after Cycle 2, and at the end of Cycle 8. Up to 28 days after the last administration of the study drug.
