Phase I Combination w/ Epirubicin

DLT: any of the following considered related to ixabepilone, epirubicin or combination occurring in Cycle 1: Absolute neutrophil count <500 cells/mm^3 for ≥7 consecutive days or febrile neutropenia of any duration;Grade(Gr)4 thrombocytopenia <25,000 cells/mm^3 or Gr3 w/bleeding requiring platelet transfusion;Any other drug-related Gr3/4 non-hematologic toxicity except Gr3 injection site reaction, fatigue, transient arthralgia/myalgia;Delayed recovery to Gr≤1 or baseline (except for alopecia) from toxicity related to treatment w/ ixabepilone + epirubicin delaying initiation of next cycle ≥3 wks

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.

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

Pharmacokinetics (PK) is a branch of pharmacology concerned with the rate at which drugs are absorbed, distributed, metabolized, and eliminated by the body. Cmax=maximum observed plasma concentration of single-dose ixabepilone administered with IV dose of epirubicin 75 mg/m^2, derived from plasma concentration versus time data.

PK is a branch of pharmacology concerned with the rate at which drugs are absorbed, distributed, metabolized, and eliminated by the body. AUC(INF)=area under the plasma concentration-time curve from time zero extrapolated to infinite time of single-dose ixabepilone administered with IV dose of epirubicin 75 mg/m^2.

PK is a branch of pharmacology concerned with the rate at which drugs are absorbed, distributed, metabolized, and eliminated by the body. T-Half=terminal-phase elimination half-life in plasma of single-dose ixabepilone administered with IV dose of epirubicin 75 mg/m^2, derived from plasma concentration versus time data.

PK is a branch of pharmacology concerned with the rate at which drugs are absorbed, distributed, metabolized, and eliminated by the body.

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.
