The addition of CDK4 and 6 inhibitors (abemaciclib, palbociclib or ribociclib) to endocrine therapy, as first-line treatment or following progression after initial endocrine therapy, significantly increased progression-free survival, objective response rates and in some trials overall survival, compared with endocrine therapy alone in HR+ and HER2- breast metastatic breast cancer. These CDK4 and 6 inhibitors are now approved in this context and have become a new standard of care. A hypothesis-generating exploratory analysis suggested that the addition of abemaciclib to endocrine therapy showed the largest effects in subgroups of women with indicators of poor prognosis, although these data require confirmation. This review provides updated clinical trial data for all three drugs in metastatic breast cancer, focusing on abemaciclib, the most recently approved agent.

Purpose To compare the effectiveness and tolerability of epirubicin and paclitaxel (EP) with epirubicin and cyclophosphamide (EC) as first-line chemotherapy for metastatic breast cancer (MBC). Patients and Methods Patients previously untreated with chemotherapy (except for adjuvant therapy) were randomly assigned to receive either EP (epirubicin 75 mg/m2 and paclitaxel 200 mg/m2) or EC (epirubicin 75 mg/m2 and cyclophosphamide 600 mg/m2) administered intravenously every 3 weeks for a maximum of six cycles. The primary outcome was progression-free survival; secondary outcome measures were overall survival, response rates, and toxicity. Results Between 1996 and 1999, 705 patients (353 EP patients and 352 EC patients) underwent random assignment. Patient characteristics were well matched between the two groups, and 71% of patients received six cycles of treatment. Objective response rates were 65% for the EP group and 55% for the EC group (P = .015). At the time of analysis, 641 patients (91%) had died. Median progression-free survival time was 7.0 months for the EP group and 7.1 months for the EC group (hazard ratio = 1.07; 95% CI, 0.92 to 1.24; P = .41), and median overall survival time was 13 months for the EP group and 14 months for the EC group (hazard ratio = 1.02; 95% CI, 0.87 to 1.19; P = .8). EP patients, compared with EC patients, had more grade 3 and 4 mucositis (6% v 2%, respectively; P = .0006) and grade 3 and 4 neurotoxicity (5% v 1%, respectively; P < .0001). Conclusion In terms of progression-free survival and overall survival, there was no evidence of a difference between EP and EC. The data demonstrate no additional advantage to using EP instead of EC as first-line chemotherapy for MBC in taxane-naïve patients.

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]

Aims and background Anthracyclines such as doxorubicin play a central role in the management of advanced breast cancer. Unfortunately, the clinical benefits of anthracyclines are limited by cardiotoxicity that can lead to the development of potentially fatal congestive heart failure. In order to limit anthracycline-related cardiotoxicity, liposomal formulations of doxorubicin have been developed. This retrospective analysis evaluated the experience obtained with non-pegylated liposomal doxorubicin as first-line therapy in 34 patients with metastatic breast cancer. Methods Patients received non-pegylated liposomal doxorubicin in combination with either cyclophosphamide (n = 14) or docetaxel (n = 20) for up to eight cycles, and efficacy and safety were assessed according to standard criteria. Results The overall response rate was 71%. The median progression-free survival was 8 months in patients receiving non-pegylated liposomal doxorubicin plus cyclophosphamide and 13.8 months in those receiving non-pegylated liposomal doxorubicin plus docetaxel (P = 0.2). The most commonly observed toxicities were grade 1–2 leucopenia, alopecia, nausea and vomiting; no grade 3–4 toxicities were observed. Overall, three patients (9%) experienced grade 1 cardiac toxicity. Conclusions Our results support the use of non-pegylated liposomal doxorubicin as an alternative to conventional doxorubicin formulations in combination regimens for the first-line therapy of metastatic breast cancer.
