Purpose The mammalian target of rapamycin inhibitor everolimus targets aberrant signaling through the PI3K/AKT/mammalian target of rapamycin pathway, a mechanism of resistance to anti-estrogen therapy in estrogen receptor (ER)–positive breast cancer. We hypothesized that everolimus plus the selective ER downregulator fulvestrant would be more efficacious than fulvestrant alone in ER-positive metastatic breast cancer resistant to aromatase inhibitor (AI) therapy. Patients and Methods This randomized, double-blind, placebo-controlled, phase II study included 131 postmenopausal women with ER-positive, human epidermal growth factor receptor 2–negative, AI-resistant metastatic breast cancer randomly assigned to fulvestrant (500 mg days 1 and 15 of cycle 1, then day 1 of cycles 2 and beyond) plus everolimus or placebo. The study was designed to have 90% power to detect a 70% improvement in median progression-free survival from 5.4 months to 9.2 months. Secondary end points included objective response and clinical benefit rate (response or stable disease for at least 24 weeks). Prophylactic corticosteroid mouth rinses were not used. Results The addition of everolimus to fulvestrant improved the median progression-free survival from 5.1 to 10.3 months (hazard ratio, 0.61 [95% CI, 0.40 to 0.92]; stratified log-rank P = .02), indicating that the primary trial end point was met. Objective response rates were similar (18.2% v 12.3%; P = .47), but the clinical benefit rate was significantly higher in the everolimus arm (63.6% v 41.5%; P = .01). Adverse events of all grades occurred more often in the everolimus arm, including oral mucositis (53% v 12%), fatigue (42% v 22%), rash (38% v 5%), anemia (31% v. 6%), diarrhea (23% v 8%), hyperglycemia (19% v 5%), hypertriglyceridemia (17% v 3%), and pneumonitis (17% v 0%), although grade 3 to 4 events were uncommon. Conclusion Everolimus enhances the efficacy of fulvestrant in AI-resistant, ER-positive metastatic breast cancer.

Abstract Background Trastuzumab and fulvestrant combination therapy is one of the treatment options for patients with hormone receptor- and human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer; however, there are limited studies evaluating the efficacy of this combination therapy. Methods We retrospectively reviewed the data of women with hormone receptor- and HER2-positive metastatic breast cancer who received trastuzumab and fulvestrant combination therapy between August 1997 and August 2020 at the Cancer Institute Hospital. The primary endpoint of this study was progression-free survival, and the secondary endpoints were response rate, overall survival and safety. Results We reviewed the data of 1612 patients with recurrent or metastatic breast cancer, of which 118 patients were diagnosed with hormone receptor- and HER2-positive breast cancer. Of these, 28 patients who received trastuzumab and fulvestrant combination therapy were eligible for this study. The median treatment line for advanced breast cancer was 6 (range, 1–14), the median progression-free survival was 6.4 months (95% confidence interval [CI], 3.46–8.17), and the median overall survival was 35.3 months (95% CI, 20.0–46.7). Of the 28 patients, partial response was observed in 1 (4%), stable disease in 17 (61%), and progressive disease in 10 (36%) patients. The disease control rate was 64%. Adverse events of grade ≥ 3 were not observed. Conclusions Trastuzumab and fulvestrant combination therapy showed moderate clinical efficacy and no severe toxicity after standard anti-HER2 treatment, which is a reasonable treatment option for patients with hormone receptor- and HER2-positive metastatic breast cancer. These data contribute to understanding the efficacy of trastuzumab and fulvestrant combination therapy as control data for further development of anti-HER2 agents plus hormone therapy.

Aim: To examine the effectiveness of eribulin mesylate for metastatic breast cancer post cyclin-dependent kinase inhibitor (CDKi) 4/6 therapy. Materials & methods: US community oncologists reviewed charts of patients who had received eriublin from 3 February 2015 to 31 December 2017 after prior CDKi 4/6 therapy and detailed their clinical/treatment history, clinical outcomes (lesion measurements, progression, death) and toxicity. Results: Four patient cohorts were created according to eribulin line of therapy: second line, third line, per US label and fourth line with objective response rates/clinical benefit rates of 42.2%/58.7%, 26.1%/42.3%, 26.7%/54.1% and 17.9%/46.4%, respectively. Median progression-free survival/6-month progression-free survival (79.5% of all patients censored) by cohort was: 9.7 months/77.3%, 10.3 months/71.3%, not reached/70.4% and 4.0 months/0.0%, respectively. Overall occurrence of neutropenia = 23.5%, febrile neutropenia = 1.3%, peripheral neuropathy = 10.1% and diarrhea = 11.1%. Conclusion: Clinical outcome and adverse event rates were similar to those in clinical trials and other observational studies. Longer follow-up is required to confirm these findings.

Overexpression of the human epidermal growth factor receptor (HER2) oncoprotein in breast cancer patients, is one of the biological characteristics of the disease that determines the choice of appropriate systemic treatment. We report the case of a 41-year-old woman, with relapsing HER2-positive breast cancer in cerebral and pulmonary cells. The patient underwent multimodal first Iine treatment including pertuzumab, trastuzumab and docetaxel and panencephalic radiotherapy with good response and progression-free survival for approximately 16 months. Subsequently, further to a encephalic progression of the disease, the patient was treated in second line with the combination lapatinib + capecitabine which induced further encephalic response and disease control for additional 20 months (Oncology).

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.

The current therapeutic landscape of luminal human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer (mBC) is fundamentally evolving, particularly in the advent of molecularly targeted therapies, such as inhibitors of mammalian target of rapamycin and cyclin-dependent kinase 4/6 (CDK4/6). In the context of CDK4/6 inhibitors, landmark clinical trials for palbociclib (PALOMA-1, PALOMA-2, PALOMA-3), ribociclib (MONALEESA-2, MONALEESA-3, MONALEESA-7) and abemaciclib (MONARCH-1, MONARCH-2, MONARCH-3) have provided solid data regarding progression-free survival and overall response rate, justifying the introduction of this class of drugs into our therapeutic armoury. However, several clinical questions remain open. One of the most relevant issues faced in practice is that of the optimum sequencing of CDK4/6 inhibitors, particularly given the wide range of therapeutic options open to clinicians treating luminal mBC. In this brief commentary, we would like to focus on the best sequence for CDK4/6 inhibitors and their place in this growing, complex scenario.

Purpose This phase III study compared the efficacy and safety of bevacizumab (BV) when combined with several standard chemotherapy regimens versus those regimens alone for first-line treatment of patients with human epidermal growth factor receptor 2–negative metastatic breast cancer. Patients and Methods Patients were randomly assigned in 2:1 ratio to chemotherapy plus BV or chemotherapy plus placebo. Before random assignment, investigators chose capecitabine (Cape; 2,000 mg/m2 for 14 days), taxane (Tax) -based (nab-paclitaxel 260 mg/m2, docetaxel 75 or 100 mg/m2), or anthracycline (Anthra) -based (doxorubicin or epirubicin combinations [doxorubicin/cyclophosphamide, epirubicin/cyclophosphamide, fluorouracil/epirubicin/cyclophosphamide, or fluorouracil/doxorubicin/cyclophosphamide]) chemotherapy administered every 3 weeks. BV or placebo was administered at 15 mg/kg every 3 weeks. The primary end point was progression-free survival (PFS). Secondary end points included overall survival (OS), 1-year survival rate, objective response rate, duration of objective response, and safety. Two independently powered cohorts defined by the choice of chemotherapy (Cape patients or pooled Tax/Anthra patients) were analyzed in parallel. Results RIBBON-1 (Regimens in Bevacizumab for Breast Oncology) enrolled 1,237 patients (Cape cohort, n = 615; Tax/Anthra cohort, n = 622). Median PFS was longer for each BV combination (Cape cohort: increased from 5.7 months to 8.6 months; hazard ratio [HR], 0.69; 95% CI, 0.56 to 0.84; log-rank P < .001; and Tax/Anthra cohort: increased from 8.0 months to 9.2 months; HR, 0.64; 95% CI, 0.52 to 0.80; log-rank P < .001). No statistically significant differences in OS between the placebo- and BV-containing arms were observed. Safety was consistent with results of prior BV trials. Conclusion The combination of BV with Cape, Tax, or Anthra improves clinical benefit in terms of increased PFS in first-line treatment of metastatic breast cancer, with a safety profile comparable to prior phase III studies.

Purpose This phase III study compared the efficacy and safety of bevacizumab combined with standard chemotherapy regimens versus chemotherapy alone as second-line treatment of patients with human epidermal growth factor receptor 2 (HER2) –negative metastatic breast cancer. Patients and Methods Patients were randomly assigned 2:1 to chemotherapy + bevacizumab or to chemotherapy + placebo. Before random assignment, investigators chose capecitabine, a taxane (paclitaxel, nab-paclitaxel, or docetaxel), gemcitabine, or vinorelbine. Dosing for bevacizumab or placebo was 15 mg/kg every 3 weeks or 10 mg/kg every 2 weeks, depending on chemotherapy regimen. The primary end point was progression-free survival (PFS). Secondary end points included overall survival, PFS by chemotherapy cohort, objective response rate (ORR), duration of objective response, 1-year survival rate, and safety. Results RIBBON-2 enrolled 684 patients (225, chemotherapy + placebo; 459, chemotherapy + bevacizumab). The combination of bevacizumab with chemotherapy demonstrated a statistically significant benefit. Median PFS increased from 5.1 to 7.2 months (stratified hazard ratio for PFS, 0.78; 95% CI, 0.64 to 0.93; P = .0072). The 10% improvement in ORR between the placebo- and bevacizumab-containing arms (39.5% v 29.6%; P = .0193), although not statistically significant, was consistent with previous trials. There was no statistically significant difference in overall survival. The most common grade ≥ 3 adverse events (AEs) related to bevacizumab treatment were hypertension (9.0%) and proteinuria (3.1%). There was an increased number of AEs leading to study discontinuation in the chemotherapy + bevacizumab arm compared with the chemotherapy + placebo arm (13.3% v 7.2%). Conclusion The combination of bevacizumab with commonly used chemotherapies improved PFS in the second-line treatment of patients with HER2-negative metastatic breast cancer, with a safety profile comparable with that in prior phase III studies.
