Purpose To evaluate the combination of docetaxel, vinorelbine, and trastuzumab as neoadjuvant therapy for human epidermal growth factor receptor 2 (HER2) –overexpressing breast cancer. Patients and Methods Patients with stage IIB or III breast cancer, including inflammatory disease, and HER2 overexpression (determined by fluorescent in situ hybridization) were treated with six cycles of docetaxel 60 mg/m2 and vinorelbine 45 mg/m2 administered every 14 days with granulocyte colony-stimulating factor and quinolone prophylaxis. Trastuzumab was administered as a 4 mg/kg loading dose followed by 2 mg/kg weekly for 12 weeks. The primary efficacy end point was pathologic complete response (pCR) in the breast. Results Of 31 enrolled patients, 68% had T3 or T4 tumors and 90% were clinically node positive. Twelve patients (39%; 95% CI, 21.6% to 55.9%) achieved pCR in the breast and lymph nodes and 14 patients (45%; 95% CI, 27.6% to 62.7%) achieved pCR in the breast alone, and 19 patients (61%; 95% CI, 44.1% to 78.4%) were node negative after neoadjuvant therapy. Clinical response was documented in 29 patients (94%; 95% CI, 78.6% to 99.2%) with 26 complete responses (84%; 95% CI, 70.9% to 96.8%). The most commonly reported grade 3/4 toxicities were neutropenia (97%), febrile neutropenia (22%), anemia (6%), mucositis/stomatitis (6%), constipation (6%), and skin rash (6%). Conclusion With clinical response and pCR rates of 94% and 39%, respectively, docetaxel, vinorelbine, and trastuzumab is a highly active neoadjuvant therapy for HER2-overexpressing locally advanced breast cancer. Although well tolerated overall, significant febrile neutropenia was observed despite prophylactic measures; therefore, evaluating a similar regimen using lower docetaxel and/or vinorelbine doses is warranted.

Purpose To evaluate the efficacy and safety of docetaxel, cisplatin, and trastuzumab as primary systemic therapy for human epidermal growth factor receptor 2 (HER2) –positive, locally advanced breast cancer (LABC). Patients and Methods Forty-eight patients with immunohistochemistry-confirmed HER2-positive LABC or inflammatory breast cancer received 12 weeks of docetaxel, cisplatin, and trastuzumab with filgrastim, followed by surgery, adjuvant doxorubicin and cyclophosphamide, and locoregional radiotherapy with or without tamoxifen. The primary end point was pathologic complete response (pCR) in breast. Results Baseline mean tumor size was 9.2 cm (range, 4 to 32 cm). pCR occurred in breast in 11 patients (23%; 95% CI, 12% to 37%) and breast and axilla in eight patients (17%; 95% CI, 8% to 30%). pCR rates in breast (HER2 positive, seven of 30 patients, 23% v HER2 negative, four of 18 patients, 22%; P > .05) and breast and axilla (four of 30 patients, 13% v four of 18 patients, 22%, respectively; P > .05) were similar regardless of HER2 status by fluorescence in situ hybridization (FISH). At a median follow-up time of 43 months, 4-year progression-free survival (PFS) rate was 81% (95% CI, 64% to 90%); overall survival (OS) rate was 86% (95% CI, 71% to 94%). In patients with pCR in breast and axilla, PFS and OS rates were 100% (95% CI, inestimable). In patients without pCR, PFS rate was 76% (95% CI, 57% to 88%; P = .15, log-rank test), and OS rate was 83% (95% CI, 66% to 92%; P = .21). Survival rates were similar regardless of FISH status. There were only two grade 4 adverse events. Conclusion Twelve weeks of docetaxel, cisplatin, and trastuzumab is clinically active and leads to excellent survival in patients with large, HER2-positive tumors.

Purpose MONARCH 2 ( ClinicalTrials.gov identifier: NCT02107703) compared the efficacy and safety of abemaciclib, a selective cyclin-dependent kinase 4 and 6 inhibitor, plus fulvestrant with fulvestrant alone in patients with advanced breast cancer (ABC). Patients and Methods MONARCH 2 was a global, double-blind, phase III study of women with hormone receptor-positive and human epidermal growth factor receptor 2-negative ABC who had progressed while receiving neoadjuvant or adjuvant endocrine therapy (ET), ≤ 12 months from the end of adjuvant ET, or while receiving first-line ET for metastatic disease. Patients were randomly assigned 2:1 to receive abemaciclib or placebo (150 mg twice daily) on a continuous schedule and fulvestrant (500 mg, per label). The primary end point was investigator-assessed progression-free survival (PFS), and key secondary end points included overall survival, objective response rate (ORR), duration of response, clinical benefit rate, quality of life, and safety. Results Between August 2014 and December 2015, 669 patients were randomly assigned to receive abemaciclib plus fulvestrant (n = 446) or placebo plus fulvestrant (n = 223). Abemaciclib plus fulvestrant significantly extended PFS versus fulvestrant alone (median, 16.4 v 9.3 months; hazard ratio, 0.553; 95% CI, 0.449 to 0.681; P < .001). In patients with measurable disease, abemaciclib plus fulvestrant achieved an ORR of 48.1% (95% CI, 42.6% to 53.6%) compared with 21.3% (95% CI, 15.1% to 27.6%) in the control arm. The most common adverse events in the abemaciclib versus placebo arms were diarrhea (86.4% v 24.7%), neutropenia (46.0% v 4.0%), nausea (45.1% v 22.9%), and fatigue (39.9% v 26.9%). Conclusions Abemaciclib at 150 mg twice daily plus fulvestrant was effective, significantly improving PFS and ORR and demonstrating a tolerable safety profile in women with hormone receptor-positive and human epidermal growth factor receptor 2-negative ABC who progressed while receiving ET.
