Primary Outcome Measures:
  • Number of Participants With Best Tumor Response as Assessed With Response Evaluation Criteria in Solid Tumors (RECIST) [ Time Frame: Baseline to 6 weeks (end of Cycle 2) ] [ Designated as safety issue: No ]
    RECIST definitions: Complete reponse (CR)=disappearance of all nontarget lesions; partial response (PR)=at least 30% reduction in the sum of the longest diameter (LD) of all target lesions in reference to the baseline sum LD; stable disease (SD)=neither PR nor progressive disease (PD) criteria were met; PD=at least 20% increase in the sum of the LD of all target lesions, taking as reference the smallest sum LD recorded at or following baseline. Tumor status assessed by investigator.

  • Percentage of Participants With Best Response to Treatment of Complete or Partial [ Time Frame: Baseline to 6 weeks (end of Cycle 2) ] [ Designated as safety issue: No ]
    The tumor response rate is defined as the number of participants with a best tumor response of CR or PR (as assessed by the investigator according to RECIST criteria), divided by the number of participants randomized in that arm.


Secondary Outcome Measures:
  • Percentage of Triple-negative (TN) Participants With Best Response to Treatment of Complete or Partial [ Time Frame: Baseline to 6 weeks (end of Cycle 2) ] [ Designated as safety issue: No ]
    The tumor response rate is defined as the total number of participants whose best response is CR or PR, divided by the number of randomized participants. Participants not evaluable for response are considered to be nonresponders. TN participants are those with tumors that do not express estrogen or progesterone receptors and that do not over express human epidermal growth factor receptor 2 (HER2).

  • Percentage of Nontriple-negative (NTN) Participants With Best Response to Treatment of Complete or Partial Per Cohort [ Time Frame: Baseline to 6 weeks (end of Cycle 2) ] [ Designated as safety issue: No ]
    The tumor response rate is defined as the total number of participants whose best response is CR or PR, divided by the number of randomized participants. Participants not evaluable for response are considered to be nonresponders. NTN participants are who are not TN participants (TN participants are those with tumors that do not express estrogen or progesterone receptors and that do not overexpress HER2) and who received ixabepilone plus capecitabine or docetaxel plus capecitabine.

  • Number of Participants With Death, Adverse Events (AEs), Drug-related AEs, Serious AEs (SAEs), Drug-related SAEs, AEs Leading to Discontinuation (AEDs), Drug-related AEDs, and Drug-related Peripheral Neuropathy [ Time Frame: Baseline to end of Cycle 1 (21 days), continuously ] [ Designated as safety issue: Yes ]
    An AE is any new untoward medical occurrence or worsening of a preexisting medical condition that does not necessarily have a causal relationship with this treatment. An SAE is any untoward medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency or abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization. Drug-related=possibly, probably, or certainly related or of unknown relationship to study treatment. Grade 3=Severe, Grade 4=Life-threatening.

  • Number of Participants With Abnormalities in Hematology Laboratory Results by Worst Common Terminology Criteria (CTC) Grade [ Time Frame: Baseline in Cycle 1 (21 days) and then prior to start of each 21-day cycle ] [ Designated as safety issue: Yes ]
    CTC Grade 1=Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2=Moderate; minimal, local or noninvasive intervention indicated. Grade 3=Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling. Grade 4=Life-threatening consequences; urgent intervention indicated.

  • Number of Participants With Abnormalities in Serum Chemistry Laboratory Results [ Time Frame: Baseline in Cycle 1 (21 days) and then prior to start of each 21-day cycle ] [ Designated as safety issue: Yes ]
    ULN=Upper limit of normal among all laboratory ranges. Alanine aminotransferase (ALT) Grade 1:>ULN to 2.5*ULN; Grade 2: >2.5 to 5.0*ULN; Grade 3: >5.0 to 20.0*ULN; Grade 4: >20.0*ULN. Aspartate aminotransferase (AST) Grade 1: >ULN to 2.5*ULN; Grade 2: >2.5 to 5.0*ULN; Grade 3: >5.0 to 20.0*ULN; Grade 4: >20.0*ULN. Total bilirubin Grade 1: >ULN to 1.5*ULN; Grade 2: >1.5 to 3.0*ULN; Grade 3: >3.0 to 10.0*ULN; Grade 4: >10.0*ULN. Creatine Grade 1: >ULN to 1.5*ULN; Grade 2: 1.5 to 3.0*ULN; Grade 3: >3.0 to 6.0*ULN; Grade 4: >6.0*ULN.

  • Time to Progression [ Time Frame: Baseline to date progressive disease reported ] [ Designated as safety issue: No ]
    Time to progression is defined as the time from date of randomization until the date that PD is first reported. Participants who die without a reported prior progression are considered to have progressed on the day of their death. Those who did not progress or die are censored at the day of their last tumor assessment.

  • Duration of Response [ Time Frame: Baseline (date of randomization) to date CR or PR criteria first met ] [ Designated as safety issue: Yes ]
    Duration of overall response is computed for participants whose best response is either PR or CR and is measured from the time measurement criteria are first met for CR or PR (whichever status is recorded first) until the first date of documented PD or death. Participants who did not relapse or die are censored on the date of their last tumor assessment.

  • Median Number of Treatment Cycles [ Time Frame: Day 1 to end of Cycle 18, maximum (54 weeks) ] [ Designated as safety issue: No ]
    The first dosing date is defined as the date of the first dose of chemotherapy or capecitabine, whichever was administered first. Cycles are defined as the time from Day 1 of the cycle until the day before the next cycle. The last cycle per participant is the 21-day period following Day 1 of that cycle.
