Brief summary
In this trial we will evaluate ABI-007 with gemcitabine and epirubicin, utilizing the biweekly pegfilgrastim support, in order to further improve upon the effectiveness and favorable toxicity of this triplet.
Detailed description
Upon determination of eligibility, patients will be receive both induction neo-adjuvant regimen and a postoperative adjuvant regimen: Induction Neo-adjuvant: Epirubicin + Gemcitabine + ABI-007 + Pegfilgrastim Postoperative Adjuvant: Gemcitabine + ABI-007 + Pegfilgrastim Upon completion of chemotherapy, all ER and/or PR+ patients will receive Tamoxifen or an aromatase inhibitor at physician discretion.
Interventions
Gemcitabine 2000 mg/m2 IV D1 q 14 days x 6 cycles
Epirubicin 50 mg/m2 D1 q 14 days x 6 cycles
ABI-007 175 mg/m2 D1 q 14 days x 6 cycles

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pathologic Complete Response | 18 months | For the purpose of this study, a pathologic complete response (pCR) was defined as no evidence of residual invasive tumor in the breast (pT0) and axillary lymph nodes (pN0), gross or microscopic, in the sample removed at the time of surgical resection. Residual ductal or lobular carcinoma in situ was not considered in pCR assessments. Percentage of participants who experienced pCR is reported. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Clinical Response Rates | 18 months | Clinical response rate is defined as percentage of patients whose disease decreased (Partial response - PR) and/or disappeared (Complete response - CR) after treatment). Clinical tumor response was defined as complete if there was no clinical evidence of palpable tumor in either the breast or axilla at the time of surgery. Reduction of total tumor size \>50 % at the time surgery was considered a clinical partial response. Evaluations are based on Response Evaluation Criteria in Solid Tumors (RECIST) |
| Rates of Breast Preservation | 18 months | Number of patients who underwent breast conservation after neo adjuvant chemotherapy |
| Time to Disease Progression | 36 months | Time to progression is the length of time from the start of treatment until the disease progressed. Progressive disease is defined as an increase of \>25% in the total calculated product of the tumor's measurements or development of a new lesion. Evaluations are based on Response Evaluation Criteria in Solid Tumors (RECIST) |

Outcome results
Pathologic Complete Response
For the purpose of this study, a pathologic complete response (pCR) was defined as no evidence of residual invasive tumor in the breast (pT0) and axillary lymph nodes (pN0), gross or microscopic, in the sample removed at the time of surgical resection. Residual ductal or lobular carcinoma in situ was not considered in pCR assessments. Percentage of participants who experienced pCR is reported.
Time frame: 18 months
Population: 7 patients did not complete the study. Only the patients who had surgical procedures following neoadjuvant chemotherapy were included in the analysis as pathologic complete response is assessing the gross or microscopic response in the tissue sample resected at the time of surgery.
