Metastatic Breast Cancer
Conditions
Brief summary
Primary objective is to determine the effectiveness of the combination of bortezomib and doxorubicin in patients with metastatic breast cancer. The trial format is a single arm Phase II design wherein patients are treated with bortezomib IV on days 1, 4, 8, and 11 and with doxorubicin IV on days 1 and 8 of a 21-day cycle.
Interventions
DRUGPS-341, doxorubicin
bortezomib:1.3 mg/m2 IVP over 3-5 sec. days 1, 4, 8, 11 of 21 day cycle doxorubicin: 20 mg/m2 IV over 3-5 min. days 1,8 (one hour after bortezomib) of 21 day cycle

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Overall Response Rate | Every two cycles/42 days, up to 7 months | Determine the clinical efficacy of bortezomib and doxorubicin in patients with metastatic breast cancer. Overall response rate is defined as both complete and partial response per RECIST, where complete response is the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10mm. Partial response is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Progressive disease is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5mm. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time to Progression | Up to one year | Number of days to progression, where progression is defined as the number of days from the day of first study drug administration to the day the patient experiences an event of disease progression, or the appearance of one or more new lesions and/or unequivocal progression of existing non-target lesions. If a patient has not experienced an event of disease progression, then the patient's data will be censored at the date of the last available evaluation. Progression-free survival will be summarized by medium time to progression. |

Recruitment details
This study enrolled subjects with metastatic breast cancer from the Wisconsin Oncology Network (WON), which is driven by investigators at the University of Wisconsin Carbone Cancer Center, from August of 2006 through February of 2008.
