Background: Owing to the need for effective and tolerable new regimens for the treatment of patients with metastatic breast cancer (MBC) previously treated with anthracyclines and/or taxanes, we aimed to assess the activity and safety of the gemcitabine plus capecitabine combination chemotherapy. Methods: Sixty-four patients were enrolled. Treatment consisted of gemcitabine 1,000 mg/m2 intravenously on days 1 and 8, plus oral capecitabine at 1,250 mg/m2 twice daily on days 1-14. The primary end point was the overall response rate (ORR). Secondary objectives included the disease control rate (DCR), overall survival (OS), progression-free survival (PFS), toxicity, and predictive factors. Results: In the 64 patients, the ORR and DCR was 28.1 and 67.2%. Median OS and PFS were 23.6 and 13.4 months, respectively. Toxicities were mild and curable. Conclusion: The combination of gemcitabine and capecitabine is an effective and tolerable treatment for MBC previously treated with anthracyclines and/or taxanes.

Abstract Background Treatment options for metastatic breast cancer (MBC) refractory to anthracyclines and taxanes are limited. In a phase III trial, eribulin demonstrated a significant improvement in overall survival compared to treatment of physician’s choice, but had limited tolerability because of neutropenia and peripheral neuropathy. Based on prior studies of alternative treatment schedules with other therapies, we hypothesized that a low-dose metronomic schedule of eribulin would permit patients to remain on treatment more consistently without treatment delays, resulting in longer time to progression, and improved toxicity profile. Methods We conducted a multi-site single arm, phase II trial patients with MBC. All patients were treated with metronomic eribulin (0.9 mg/m2 administered intravenously on days 1, 8, and 15 of a 28-day cycle.) Treatment was continued until the patient developed disease progression, unacceptable toxicity, or chose to stop the study. Patients must have had prior taxane exposure. The primary endpoint was progression-free survival. Secondary end points were overall survival, response rate, and clinical benefit rate. Exploratory biomarkers were performed to analyze change in levels of circulating endothelial cells (CECs), circulating endothelial precursors, and carbonic anhydrase IX (CAIX) with response to therapy. Findings We consented 86 patients and 59 were evaluable for final analysis. Median age was 59 years; 78% had HER2 negative tumors. The median progression-free survival (PFS) was 3.5 months with overall survival (OS) of 14.3 months. Objective response rate was 15% with clinical benefit rate of 48%. Reported grade 3 neutropenia and peripheral neuropathy were 18% and 5%, respectively. Treatment discontinuation due to toxicity was seen in 3% of patients. Interpretation Metronomic weekly low-dose eribulin is an active and tolerable regimen with significantly less myelosuppression, alopecia, and peripheral neuropathy than is seen with the approved dose and schedule, allowing longer duration of use and disease control, with similar outcomes compared to the standard dose regimen.

Purpose To determine whether the addition of intravenous (IV) vinorelbine to epirubicin increased the progression-free survival in first-line treatment of metastatic breast cancer. Patients and Methods A total of 387 patients were randomly assigned to receive IV epirubicin 90 mg/m2 on day 1 and vinorelbine 25 mg/m2 on days 1 and 8, or epirubicin 90 mg/m2 IV on day 1. Both regimens were given every 3 weeks for a maximum of 1 year but discontinued prematurely in the event of progressive disease or severe toxicity. In addition, epirubicin was discontinued at a cumulative dose of 1,000 mg/m2 (950 mg/m2 from June 1999). Prior anthracycline-based adjuvant chemotherapy and prior chemotherapy for metastatic breast cancer was not allowed. Reported results were all based on intent-to-treat analyses. Results Overall response rates to vinorelbine and epirubicin, and epirubicin alone, were 50% and 42%, respectively (P = .15). The complete response rate was significantly superior in the combination arm (17% v 10%; P = .048) as was median duration of progression-free survival (10.1 months v 8.2 months; P = .019). Median survival was similar in the two arms (19.1 months v 18.0 months; P = .50). Leukopenia related complications, stomatitis, and peripheral neuropathy were more common in the combination arm. The incidences of cardiotoxicity and constipation were similar in both arms. Conclusion Addition of vinorelbine to epirubicin conferred a significant advantage in terms of complete response rate and progression-free survival, but not in terms of survival.

1087 Background: Paclitaxel/carboplatin combinations are highly active in metastatic breast cancer (MBC). We conducted a randomized, phase III, non-inferiority trial comparing paclitaxel/carboplatin (TP) with paclitaxel/epirubicin (TE) as first-line therapy for MBC. Progression-free survival (PFS) was the primary efficacy endpoint. Secondary endpoints included response rate, overall survival, tolerability, and quality of life (QoL). Methods: From June 2009 to January 2015, 231 patients were randomly assigned, 115 of whom were randomized to TP and 116 to TE. Baseline characteristics were relatively well-balanced in the two treatments. Results: After a median follow-up of 29 months, no significant difference was observed between the two treatments in objective response rate (ORR) (38.3% vs. 39.7%, respectively). Both the progression-free survival (p=0.158) and overall survival (p=0.369) were very similar between the two treatments. Both regimens were well tolerated. The main toxicities were myelosuppression, gastrointestinal reactions, and alopecia. TP showed higher grades 3–4 alopecia and higher nausea (p<0.05). TE showed higher incidence of myelosuppression than TP (p<0.05) (Table). Those patients whose epirubicin cumulative dose was more than 1000 mg/m2 did not suffer worse cardiotoxicity. Conclusions: Our study suggests that TP arm is an effective therapeutic alternative for patients with MBC, especially in those previously exposed to epirubicin in the adjuvant setting. TP has some advantages, such as less cost and less side effects (myelosuppression and fatigue). Clinical trial information: NCT02207361. [Table: see text]

Background: This phase II study was conducted to evaluate the efficacy and safety of the chemotherapy combination of gemcitabine and vinorelbine in taxane-pretreated Japanese metastatic breast cancer patients. Methods: In this multicenter, phase II, single-arm study, patients with recurrent or metastatic HER2-negative breast cancer were administered gemcitabine (1,200 mg/m2) and vinorelbine (25 mg/m2) intravenously on days 1 and 8 every 3 weeks. The primary endpoint was the objective response rate, and other endpoints included progression-free survival, overall survival, and safety. Results: A total of 42 patients were enrolled in this study. The objective response rate and clinical benefit rate were 24 and 43%, respectively. The median progression-free survival was 4.0 months. The median overall survival was 11.1 months. Grade 3/4 neutropenia was the most common hematologic toxicity, occurring in 22 patients (54%). Nonhematologic toxicity was moderate and transient, with fatigue (48%) being the most common condition and no severe adverse event reported. Conclusion: The combination of gemcitabine and vinorelbine is an effective and tolerable regimen for HER2-negative, taxane-pretreated, metastatic breast cancer patients in Japan.

1046 Background:Differences in the efficacy of various chemotherapies in patients with estrogen receptor (ER) positive metastatic breast cancer are not well understood. In the present study, we assessed the efficacy of docetaxel in patients with metastatic breast cancer according to ER expression.Methods: The efficacy of docetaxel on response rates and progression-free survival were analyzed according to ER expression in four randomized trials that included a total of 1,631 patients. Odds-ratio for tumor response was estimated with logistic regression and hazard ratio for progression-free survival was estimated with Cox proportional hazards models. Results: ER expression was assessable in 1,037 patients included in these trials (64%). ER was expressed in 601 tumors (58%). Overall, docetaxel was associated with an increased response rate (odds ratio: 2.66, 95% CI: 1.83 to 3.87) and decreased hazard of disease progression (hazard ratio: 0.85, 95% CI: 0.73 to 0.97) compared to non-docetaxel containing therapy. Docetaxel was associated with similar improvement in response rate both in patients with ER-positive (odds ratio: 2.90, 95% CI: 1.72 to 4.87) and ER-negative disease (odds ratio: 2.55, 95% CI: 1.44 to 4.51). Among all ER-positive patients, tumor response rate was 31.1% among patients who did not receive docetaxel and 46.8% among patients who did receive docetaxel. Decreased hazard of disease progression due to docetaxel was also similar in ER-positive (HR: 0.82, 95% CI: 0.67–1.00) and ER-negative cancers (HR: 0.86, 95% CI: 0.70–1.07), but these results were heterogeneous among trials. The effect of docetaxel was not different in ER-positive and ER-negative disease, both in terms of response rates and progression-free survival (interaction test, p = 0.77 and p = 0.93). Conclusions: Docetaxel increases response rates and decreases the risk of disease-progression in a statistically similar extent both in patients with ER-positive and ER-negative 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.

Purpose This randomized study compared maintenance paclitaxel with control in metastatic breast cancer patients not experiencing progression after first-line anthracycline/paclitaxel combination chemotherapy. Methods Between April 1998 and October 2003, 459 metastatic breast cancer patients received first-line combination chemotherapy with epirubicin or doxorubicin plus paclitaxel. Of these, 255 who had a response or stable disease were then randomly assigned onto the Maintenance Paclitaxel 1 (MANTA1) study, comparing eight courses of maintenance paclitaxel versus control (ie, no additional chemotherapy administration). The primary end point was progression-free survival. Results The study was prematurely concluded after a futility analysis, which was performed on 215 of the 238 patients randomly assigned within December 2002. Of these, 109 patients were assigned to maintenance paclitaxel and 106 were assigned to stopping chemotherapy. No significant difference in median progression-free survival was observed (8.0 months for maintenance paclitaxel and 9.0 months for control). There was no significant difference in median survival time (28.0 v 29.0 months). When the Bayesian method for monitoring clinical trials was applied to these data, even under an enthusiastic prior distribution, in the posterior distribution there was only an 8.6% chance of observing a 3-month improvement in median progression-free survival in the group receiving maintenance paclitaxel. After these results study accrual was closed. Conclusion Compared with control, the administration of additional courses of paclitaxel in patients who achieve disease control after six to eight courses of first-line anthracycline plus paclitaxel combination chemotherapy does not improve progression-free survival.
