- Male patients whose sexual partner(s) are WOCBP who are not willing to use adequate contraception, during the study and for 8 weeks after the end of treatment
I. Determine excellent clinical response rates (pathologic complete response [pCR]/residual cancer burden [RCB]-0 or minimal residual disease [RCB-I]) in patients with anthracycline-based chemotherapy insensitive, localized triple-negative breast cancer (TNBC) who receive 4 cycles of pegylated liposomal doxorubicin hydrochloride, bevacizumab, and everolimus (DAE) following anthracycline-based chemotherapy in the neoadjuvant setting.
I. Determine response rate after 4 cycles of DAE using radiographic imaging.
II. Correlate pathologic response with vimentin expression as measured by immunohistochemistry (IHC).
III. Determine toxicity associated 4 cycles of DAE in the neoadjuvant setting.
IV. Compare pathologic response rates to 4 cycles of DAE in mesenchymal tumors versus (vs.) non-mesenchymal tumors.
V. Compare pathologic response rates in mesenchymal tumors to 4 cycles of DAE vs. 12 weeks of weekly paclitaxel.
VI. Determine pathologic response rates for all patients who discontinue study drug due to toxicity.
I. Determine the correlation between vimentin expression by IHC and the presence of mesenchymal gene signatures at the time of initial tumor biopsy prior to neoadjuvant chemotherapy (NACT).
II. Determine rates of pCR in patients with mesenchymal tumors identified by gene signatures and compare to pCR rates in non-mesenchymal tumors.
Patients receive pegylated liposomal doxorubicin hydrochloride intravenously (IV) over about 3 hours on day 1, bevacizumab IV over 90 minutes on day 1, and everolimus orally (PO) daily. Treatment repeats every 21 days for up to 4 courses in the absence of disease progression or unacceptable toxicity. Patients will not receive bevacizumab during course 4 of therapy. Patients then undergo surgery.
After completion of study treatment, patients are followed up at 2-3 weeks.
