e11568 Background: This prospective phase II study was to investigate the efficacy and toxicity of weekly albumin-bound paclitaxel (nab-paclitaxel) and cisplatin combination in patients with metastatic breast cancer. Methods: Females with unresectable, recurrent or metastatic breast cancer were eligible for participation. Nab-paclitaxel was administered weekly at a dose of 125 mg/m2 on d1, 8, 15, followed by cisplatin 75 mg/m2 on d1, repeated every 28 days with a maximum of 6 cycles. The primary objective was overall response rate (ORR) and the second objectives were progression free survival (PFS), safety, and overall survival (OS). Results: Seventy-three women were enrolled into this study. A total of 384 chemotherapy cycles were administered with a median of 6 cycles. A high overall response rate (67.1%) was achieved in the whole population. The highest response rate was observed in the first line patients (80.6%) and in patients who had not received taxane previously (80%). After a median follow-up of 12.8 months, the median PFS was 10.5 months. For the patients receiving first-, second- and third-line or more,median PFS was 12.3, 9.0 and 7.7 months, respectively (P=0.006). Subgroup analysis showed that the highest response rate was obtained in Her-2 positive patients, followed by patients with triple negative and luminal subtypes, yielding a response rate of 77.8%, 68.8% and 63.9%, respectively (P=0.584). The corresponding median PFS was 13.6, 12.7 and 10.0 months, respectively (P=0.83). While grade 4 neutropenia occurred in 46 patients (63.0%), febrile neutropenia occurred only in 9 patients (12.3%). Grade 3 peripheral neuropathy was an accumulated dose-limiting toxicity occurring in 19 patients (26.0%), 13 of whom had to stop chemotherapy due to no recovery to grade 2 or less within 2 weeks. Other common toxicities included alopecia, nausea, vomiting and rash. Conclusions: The results of this trial add to the clinical evidence that doublet of nab-paclitaxel and cisplatin has high efficacy and a good safety profile in treatment of patients with metastatic breast cancer. Further evaluation of this regimen in metastatic breast cancer, especially triple negative subtype, is justified.

10688 Background: To determine the overall objective response rate (ORR) of Lipo-Dox plus Gemcitabine in patients with metastatic breast cancer. Patients and Methods: We are conducting an open-label, non-comparative phase II clinical trial in Simon’s 2-stage optimal design to assess the efficacy and the safety of the treatment with Gemcitabine (Gems) plus Liposomal Doxorubicin (Lipo-Dox) in patients with metastatic breast cancer. All eligible subjects received Lipo-Dox 25 mg/m2 intravenous infusion over 1 hr and follow by gemcitabine 800 mg/m2 intravenously (iv) over 30 minutes on day 1, and receive gemcitabine 800 mg/m2 intravenously (iv) over 30 minutes only on day 8 in a 21-day cycle. Results: Between July 2004 and December 2005, a total of 21 patients were enrolled in the study and total of 136 cycles of chemotherapy were delivered with a median of six per patients (range 1–16). 17 patients (80.8%) who had at least one post-treatment evaluation and exposed to at least two cycles of treatment were included in this report. Characteristics of the 17 patients: All females; median age 52 years (range 36 - 68); 16 pts had a performance status (PS) of 0 or 1 and 1 had a PS of 2 (ECOG scale); Histology: All metastatic breast cancer. The response assessment of the 17 patients: Complete response was observed in 2, partial response in 5, stable disease in 8, and progressive disease in 2 patients. Overall response rate was 41.17%. Major grade 3/4 hematological toxicities were neutropenia in 9 pts, thrombocytopenia in 2 pt and leukopenia in 5 pts. Peripheral neuropathy was noted in 1 patient (grade 2). Other toxicities occurred during the treatment cycles were all manageable or tolerable. Patient recruitment, treatment and follow-up are still ongoing. Conclusion: Liposomal Doxorubicin used in the regimen reduces the incidence of alopecia (hair loss) to grade 1 compare to the conventional doxorubicin. This study, with an overall response rate of 41.1% (CR+PR) and a rate of stable disease of 47.05%, has shown a good activity with mild and acceptable toxicities of Gemcitabine (Gems) plus Liposomal Doxorubicin (Lipo-Dox) regimen in patients with metastatic breast cancer.

PURPOSE Pyrotinib, an irreversible pan-ErbB inhibitor, showed promising antitumor activity and acceptable tolerability in a phase I trial. We assessed the efficacy and tolerability of pyrotinib versus lapatinib, both in combination with capecitabine, in women with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer in an open-label, multicenter, randomized phase II study. PATIENTS AND METHODS Chinese patients with HER2-positive relapsed or metastatic breast cancer previously treated with taxanes, anthracyclines, and/or trastuzumab were assigned (1:1) to receive 400 mg pyrotinib or lapatinib 1,250 mg orally once per day for 21-day cycles in combination with capecitabine (1,000 mg/m2 orally twice per day on days 1 to 14). The primary end point was investigator-assessed overall response rate per Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1. RESULTS Between May 29, 2015, and March 15, 2016, 128 eligible patients were randomly assigned to the pyrotinib (n = 65) or lapatinib (n = 63) treatment groups. The overall response rate was 78.5% (95% CI, 68.5% to 88.5%) with pyrotinib and 57.1% (95% CI, 44.9% to 69.4%) with lapatinib (treatment difference, 21.3%; 95% CI, 4.0% to 38.7%; P = .01). The median progression-free survival was 18.1 months (95% CI, 13.9 months to not reached) with pyrotinib and 7.0 months (95% CI, 5.6 to 9.8 months) with lapatinib (adjusted hazard ratio, 0.36; 95% CI, 0.23 to 0.58; P < .001). The most frequent grade 3 to 4 adverse events were hand-foot syndrome in 16 of 65 patients (24.6%) in the pyrotinib group versus 13 of 63 (20.6%) in the lapatinib group; diarrhea in 10 patients (15.4%) versus three patients (4.8%), respectively; and decreased neutrophil count in six patients (9.2%) versus two patients (3.2%), respectively. CONCLUSION In women with HER2-positive metastatic breast cancer previously treated with taxanes, anthracyclines, and/or trastuzumab, pyrotinib plus capecitabine yielded statistically significant better overall response rate and progression-free survival than lapatinib plus capecitabine in this randomized phase II trial.

Abstract Purpose: S-1 and cyclophosphamide (CPA) can be given orally, and their combination may have great potential for treating metastatic breast cancer (MBC). A phase I study of sequential S-1 and CPA therapy was conducted in patients with MBC; the recommended doses that were determined for this regimen were 80 mg/m 2 /day for S-1 and 100 mg/m 2 /day for CPA. We then conducted a phase II study of this oral S-1 and CPA regimen. Patients and Methods: This was a single-arm, open-label, single-center prospective phase II study to evaluate the efficacy of a sequential S-1 and CPA regimen for MBC. S-1 was administered orally 2´/day for 14 consecutive days, and then CPA was administered orally 1´/day for 14 consecutive days in a repeating 4-week cycle (S-1 for 2 weeks, CPA for 2 weeks). The primary endpoint was the overall response rate (ORR). Secondary endpoints included the overall survival (OS), progression-free survival (PFS), clinical benefit rate (CBR) and safety. Results: Thirty-six patients were enrolled in this study. The overall response was complete response in 0 (0%), partial response in 12 (33.3%), stable disease in 12 (33.3%), and progressive disease in 11 (30.1%) patients. The ORR was 33.3% (12/36). The CBR was 66.7% (24/36). The mean PFS was 9.5 months (95%CI: 7.1–11.9 months). The OS was 20.2 months (95%CI: 15.0–25.6 months) Grade 3/4 adverse events included neutropenia in seven patients (19.4%). Dose reductions because of adverse events occurred in 12 patients (33.3%). There was no treatment-related mortality. Conclusion: The combination of sequential therapy with S-1 and CPA was tolerable and had efficacy with good disease control. Sequential therapy with S-1 and CPA is a feasible new treatment option for patients with MBC.

PURPOSE The National Cancer Institute of Canada-Clinical Trials Group (NCIC-CTG) conducted a phase II study to assess the efficacy and toxicity of docetaxel as first-line chemotherapy in metastatic breast cancer (MBC). PATIENTS AND METHODS Fifty-one patients with measurable MBC were studied. Three patients were ineligible and were excluded from analysis. The planned dose of docetaxel was 100 mg/m2 intravenously (i.v.) every 3 weeks. Prior adjuvant chemotherapy was allowed if at least 12 months had elapsed from completion of treatment to recurrence. RESULTS The most severe toxicity was granulocytopenia. Ten patients (20.8%) were hospitalized for febrile neutropenia. The protocol was amended to a starting dose of 75 mg/m2 for the last 16 patients. Sixty percent of patients experienced hypersensitivity reactions (HSRs). After two protocol amendments, the use of a premedication regimen of oral dexamethasone and i.v. H1 and H2 blockers prevented significant HSRs. Edema developed in 62% of patients and was cumulative, was present in 50% who received greater than 400 mg/m2, and was not improved by premedication regimens. Following an independent radiology review, 22 partial remissions and four complete responses in 47 assessable patients were confirmed (response rate, 55%; 95% confidence interval [CI], 40% to 69%). The response rate for 15 assessable patients registered at 75 mg/m2 was 40% (95% CI, 16% to 67%); for 32 assessable patients registered at 100 mg/m2, the response rate was 63%, (95% CI, 43% to 78%). CONCLUSION Docetaxel is an active agent in MBC. Its activity as a single agent is comparable to many combination chemotherapy regimens and is not affected by prior adjuvant chemotherapy. Studies are ongoing to improve its therapeutic index and to incorporate docetaxel in combination chemotherapy regimens.

e11529 Background: Triple negative breast cancer cells are unable to repair double stranded DNA breaks and hence have sensitivity to platinum agents. Rapamycin acts synergistically with platinum agents to induce apoptosis and inhibit proliferation in breast cancer cell lines. Combination of RAD001 (oral mTOR inhibitor) and Carboplatin may have activity in triple-negative breast cancer. Methods: The primary objective of the study was to estimate the clinical benefit (complete remission (CR) + partial remission (PR) + stable disease (SD) >6 months) and the toxicity of this combination in women with triple negative metastatic breast cancer who have had 0-3 prior chemotherapy regimens for metastatic disease. 25 subjects were to be entered into a single stage open label Phase II study. Prior Carboplatin is allowed. Treated brain metastasis are eligible. The null hypothesis that the clinical benefit rate is ≤10% could be rejected if number of CR/PR/SD >6 months was ≥6. Originally, intravenous Carboplatin AUC 6 was to be administered every 3 weeks along with daily 5mg of RAD001 with a 3 patient run-in and then 10 mg daily. Due to a surprising amount of thrombocytopenia with this combination, the dose of Carboplatin was first amended to AUC 5 and most recently to AUC 4 with 5 mg of RAD001. Results: 18 patients have been recruited thus far. Median age is 59. There have been 1 CR, 4 PR’s and 2 SD's lasting > 6 months. One SD was achieved in a patient progressing on single agent Carboplatin at study entry. Median duration of CR+ SD +PR thus far is 13 weeks (range: 6-60 weeks). 5 patients had grade 3/4 thrombocytopenia and 4 patients had grade 3 neutropenia (no febrile neutropenia). However, since amendment of Carboplatin dose to AUC 4 the regimen has been well tolerated. 1 patient suffered from grade 3 dehydration. The estimated clinical benefit rate is 50% (95% C.I.: 24%, 76%). Median time to progression or death is 87.5 days from start of treatment; there is only 1 death to date on this study. Conclusions: The study has achieved it’s primary objective of demonstrating clinical benefit of RAD 001-Carboplatin combination in triple negative metastatic breast cancer. Dose limiting thrombocytopenia was an unexpected side effect requiring protocol amendment.

1045 Background: Triple-negative breast cancer cells are unable to repair double stranded DNA breaks and hence have sensitivity to platinum agents. The combination of carboplatin and paclitaxel administered weekly is active and well tolerated. Bevacizumab when added to paclitaxel prolonged progression-free survival in metastatic breast cancer (MBC). We investigated the activity and toxicity of paclitaxel plus carboplatin and bevacizumab in triple-negative MBC. Methods: The study’s primary objective was to estimate the objective response rate [complete (CR) + partial remission (PR)] and toxicity of the combination in women with triple negative MBC who had no prior chemotherapy for metastatic disease. The study followed the Simon's two-stage optimal design with 16 patients initially evaluated for response and toxicity and then expanding to a total of 46 patients. The null hypothesis that the objective response rate is ≤40% could be rejected if the number of CR/PR was ≥23. Paclitaxel 90mg/m2and Carboplatin AUC 2 were administered on days 1, 8, and 15 every 4 weeks, preceded by bevacizumab 10 mg/kg on days 1 and 15. Results: 45 women with triple negative MBC have been recruited thus far. Of them, 12 were premenopausal and 27 had prior (neo-)adjuvant chemotherapy. The median cycles administered were 5 (range 1-8). Of 38 evaluable patients we observed 7 CR, 22 PR’s for an objective response rate 76%. Seven patients achieved stable disease, while two had disease progression. Median duration of response was 8.1 months with median time to progression 9.2 months. Neutropenia grade 3 and 4 was experienced by 13 and 6 patients, respectively, with one toxic death due to febrile neutropenia. Other grade 3 toxicities included anemia/neurotoxicity (n=2), thrombocytopenia/diarrhea (n=1). Conclusions: Although still ongoingthe study has achieved the primary objective of demonstrating clinical activity for weekly carboplatin and paclitaxel in combination with bevacizumab in triple negative MBC. We believe that this triplet combination merits further evaluation in this patient population for whom there is no standard treatment. Clinical trial information: NCT00691379.
