Metastatic Breast Cancer, Amrubicin
Brief summary
Doxorubicin has been an integral part of the treatment of women with breast cancer for many years. Since amrubicin may have more activity than doxorubicin, as well as less cardiotoxicity, evaluation of amrubicin in the treatment of advanced breast cancer should be a priority. In this Phase II study, the investigators propose an evaluation of single-agent amrubicin as second- or third-line treatment for women with metastatic breast cancer.
Detailed description
This will be a phase I/II study where phase I will evaluate the maximum tolerated dose of amrubicin, and phase II will assess the progression free survival of patients with HER2-negative metastatic breast cancer using the dose established in the phase I portion.
Interventions
Phase I: dose-escalating portion with the starting dose of amrubicin at 90mg/m\^2 IV q21 days. Dose escalations are as follows: DL2 - 100mg/m\^2; DL3 - 110mg/m\^2; and DL4 - 120mg/m\^2. All cycles are q21 days Phase II: Amrubicin will be administered at the maximum tolerated dose established in Phase I by IV every 21 days

Recruitment details
Patients were recruited at multiple dose levels into the Dose Escalation (Phase I) portion of this study to determine the safest dose of this regime (MTD - Maximum Tolerated Dose). Upon determination of this dose, patients being treated at the MTD proceeded to the Dose Expansion (Phase II) portion of the study and additional patients were recruited

Outcome results
Progression-Free Survival (PFS) of MTD/Phase II Patients
Progression-free survival is measured from Day 1 of study drug administration to disease progression as defined by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, or death on the study. Progression is defined in RECIST v1.1 as a 20% increase in the sum of the longest diameter of target lesions, a measurable increase in a non-target lesion, or the appearance of new lesions. This outcome measure is reported for all patients treated at the same dose level and is not separated into Phase I and Phase II. The phase I and phase II results are not separated as the timing of enrollment (early in phase 1 or later phase II) is not relevant to the outcome measure.
Time frame: every 6 weeks until progressive disease
Population: Patients who received the dose level 3 MTD dose/Phase II dose (Amrubicin -110 mg/m\^2) are included in the analysis. The 3, dose level 3 phase I pts and 63 phase II pts treated at this dose level are all combined to evaluate the efficacy of the MTD/phase II dose. The phase I and phase II results are not separated out as the timing of their enrollment (early in phase 1 or later phase II) is not relevant to the outcome measure. The other 12 phase I pts who were not treated at the MTD are excluded.
| Arm | Measure | Value (MEDIAN) |

| Amrubicin | Progression-Free Survival (PFS) of MTD/Phase II Patients | 4.0 months |
Number of Patients With Adverse Events as a Measure of Safety and Tolerability
Assessments will be made through analysis of the reported incidence of treatment-emergent Serious Adverse Events (SAEs) and non-serious adverse events (AEs).
