Information on all tumor lesions was obtained at baseline by radiologic techniques, or if appropriate by physical examination (e.g. subcutaneous nodules). Measurable tumors were evaluated using Response Evaluation Criteria In Solid Tumors (RECIST) criteria, wherein complete response (CR) = disappearance of all target lesions; partial response (PR) = ≥30% decrease in the sum of the longest diameter of target lesions; progressive disease (PD)= ≥20% increase in the sum of the longest diameter of target lesions, and stable disease (SD) = small changes that do not meet above criteria.

Defined as the interval measured from the time that the measurement criteria are first met for CR or PR, whichever occurs first, until the date of documented progressive disease or death. CR= disappearance of all target lesions; PR= ≥30% decrease in the sum of the longest diameter of target lesions.

Duration of response was defined as the interval measured from the time that the measurement criteria are first met for CR or PR, whichever occurs first, until the date of documented progressive disease or death; PR= ≥30% decrease in the sum of the longest diameter of target lesions.

Participants received 35 mg/m^2 Ixabepilone as a 3-hour IV infusion following a 3- to 5-minute IV infusion of 75 mg/m^2 epirubicin every 21 days.

Total of all reporting groups

Participants received 30 mg/m^2 Ixabepilone as a 3-hour IV infusion following a 3- to 5-minute IV infusion of 75 mg/m^2 epirubicin every 21 days.

Participants received 35 mg/m^2 Ixabepilone as a 3-hour IV infusion following a 3- to 5-minute IV infusion of 75 mg/m^2 epirubicin every 21 days.

The MTD was the highest dose in which 0/6 or 1/6 participants experienced DLT with at least 2 out of no more than 6 participants experiencing DLT at the next higher dose level. The RP2D was based on the MTD and the assessment of any relevant chronic toxicity. To obtain further confidence in the RP2D, a total maximum of 30 evaluable participants were enrolled at the MTD.

The evaluable participant population consisted of participants who met the minimum safety evaluation requirements of the study: participant received ≥1 dose of ixabepilone and epirubicin in Cycle 1, completed adequate safety evaluations, and were observed for ≥21 days following the first dose or the participant experienced DLT.

AEs and SAEs considered possibly, probably, or certainly related to study treatment, graded according to Common Terminology Criteria for Adverse Events (CTCAE) Version 3.0 (Grade 1=Mild, Grade 2=Moderate, Grade 3=Severe, Grade 4=Life-threatening or disabling, Grade 5=Death).SAE= any untoward medical occurrence that at any dose results in death, is life-threatening, requires inpatient hospitalization/prolongation of existing hospitalization, results in persistent/significant disability/incapacity, is a congenital anomaly/birth defect, or is an important medical event

All participants who received at least 1 cycle of therapy were evaluable for safety; adverse events and other symptoms were graded according to CTCAE Version 3.0.
