BRAWO, a real‐world study, assessed the efficacy, quality of life (QoL) and safety of EVE + EXE in postmenopausal women with HR+/HER2– advanced breast cancer (ABC) in routine clinical practice. Postmenopausal women with HR+/HER2‐ABC with recurrence or progression after a NSAI were included. Primary Observation parameters included the evaluation of the effectiveness of EVE + EXE. A multivariate‐analysis using Cox proportional hazard model was built to identify predictors of progression. Overall, 2100 patients were enrolled (August 2012–December 2017); 2074 were evaluable for efficacy and safety analyses. Majority of patients (60.6%) received EVE + EXE as first (28.7%) or second‐line (31.9%) therapy. Visceral metastases were present in 54.1% patients. Median progression‐free survival (mPFS) reported as 6.6 months (95%CI: 6.3–7.0). Multivariate‐analysis in a subset of patients (n = 1837) found higher body mass index (BMI) and non‐visceral metastases to be independent predictors of favorable PFS. Patients with a BMI of 20 to <25 had a mPFS of 6.0 (95%CI: 5.4–6.4) and those with a BMI ≥30 had mPFS of 8.5 (95%CI: 6.9–9.9). 41.2% patients achieved stable disease and 7.3% partial response. No major changes were observed QoL; 86.4% patients received stomatitis prophylaxis and 41.4% experienced EVE related AEs of stomatitis, mainly low grade. AEs occurred in 91.2% of patients, of which stomatitis (42.6%) and fatigue (19.8%) were most frequent. The BRAWO study provides real‐world evidence of efficacy and safety of EVE + EXE in patients with HR+, HER2− ABC. A high BMI and the absence of visceral metastases were independent predictors of PFS in this cohort of patients. [ABSTRACT FROM AUTHOR]

Background: The "International Consensus Conference for Advanced Breast Cancer" was initiated more than 10 years ago. The rationale was to standardize treatment of advanced breast cancer (ABC) based on available evidence and to ensure that all ABC patients worldwide receive adequate treatment and access to new therapies. Topics of ABC7: The 7th International Consensus Conference for ABC (ABC7) took place from November 9 to 11, 2023 – as in previous years in Lisbon/Portugal. ABC7 focused not only on metastatic disease but also on locally advanced and inflammatory breast cancer. Special topics were the management of oligometastatic disease, leptomeningeal disease, brain metastases, and pregnant women with ABC. Due to the current situation worldwide, there was a special interest to patients living in conflict zones. As in previous years, patient advocates from around the world were integrated into the ABC conference and had a major input to the consensus. Rationale for the Manuscript: A German breast cancer expert panel comments on the voting results of the ABC7 panelists regarding their relevance for routine clinical practice in Germany. As with previous meetings, the ABC7 votes focused on modified or new statements. Regarding the statements not modified for the ABC7 consensus, they are discussed in the published manuscript from 2021 in which the German experts commented on the ABC6 consensus. The German comments are always based on the current recommendations of the "Breast Committee" of the Gynecological Oncology Working Group (Arbeitsgemeinschaft Gynäkologische Onkologie, AGO Mamma).

In MONALEESA-2, addition of ribociclib to letrozole resulted in significantly longer progression-free survival (PFS) in postmenopausal women with HR+HER2− advanced breast cancer (ABC). RIBociclib for the treatment of advanCed breast CAncer (RIBECCA) study investigated ribociclib plus letrozole in a patient population reflecting routine clinical practice. In this multicenter, open-label, single-arm, phase 3b study, patients with HR+HER2− ABC not amenable to curative therapy and ECOG performance status ≤ 2 received ribociclib plus letrozole (cohort A: postmenopausal women and men in first-line; cohort B: pre-/perimenopausal women in first-line [B1], patients pretreated for advanced disease [B2]). The primary endpoint was clinical benefit rate (CBR) by week 24; secondary endpoints included overall response rate (ORR), PFS, overall survival (OS), and safety. Association of patient and tumor characteristics with PFS was analyzed by multivariable Cox regression analysis. Overall, 487 patients were evaluable for efficacy, 502 for safety. By week 24, CBR was 60.8 % (95 % CI, 56.3–65.1), ORR was 19.3 % (95 % CI, 15.9–23.1). Median PFS was 21.8 months (95 % CI, 13.9–25.3) in first-line postmenopausal patients and 11.0 months (95 % CI, 8.2–16.4) in premenopausal and pretreated patients. Median OS was not reached. Higher baseline ECOG performance status, higher histological grade, and negative progesterone receptor status showed an unfavorable effect on PFS. Most common adverse events were neutropenia (50.0 %), nausea (42.0 %), and fatigue (39.2 %). In this broad population of patients with HR+HER2− ABC, efficacy and safety results of ribociclib plus letrozole were similar to those observed in pivotal trials. • RIBECCA confirmed the efficacy of ribociclib plus letrozole. • Patient characteristics as predictors for PFS under ribociclib are described. • PR, grading, ECOG, and previous therapy status were independent PFS predictors. • There were no new safety concerns in this study.

Introduction The INGE-B trial (NCT02894398) aimed to confirm the efficacy and safety data from the PALOMA trials for patients treated first line (1L) with palbociclib (PAL) and letrozole or 1L and later line with PAL and fulvestrant. In addition, efficacy and safety on the combination of PAL with anastrozole, exemestane (1L), or letrozole (later line) was investigated. Methods The prospective, multicenter, multi-cohort phase 2 trial INGE-B enrolled adult patients with locally advanced, inoperable, or metastatic HR+/HER2- breast cancer in Germany. The primary endpoint was the clinical benefit rate (CBR) in patients with measurable disease according to RECIST v1.1. Secondary endpoints were overall response rate (ORR), progression free survival (PFS), overall survival (OS), safety and quality of life. Data were analyzed with descriptive statistics. Results Between 2016 and 2018, 388 patients were enrolled at 64 German sites. Among patients with measurable disease treated with PAL in 1L (n=157), the CBR was 63.7% (100/157). Among all patients treated with PAL 1L (n=219), PFS was 20.1 months (95% CI 14.6 - 24.0) and OS was 40.9 months (95% CI 35.1-49.2). The most common grade 3/4 adverse event was neutropenia (33.4% n=77). There were no treatment-related deaths. Conclusion The INGE-B trial demonstrated good efficacy and tolerability of PAL with letrozole (1L) or fulvestrant (first and later line) in accordance with the PALOMA-trials. In addition, the so far lacking proof of efficacy and safety of PAL in combination with anastrozole or exemestane in 1L and with letrozole in later line was provided by INGE-B., (The Author(s).

Introduction: Prognosis of patients diagnosed with HER2+ early breast cancer (eBC) has substantially improved, but distant recurrences impacting quality of life and survival still occur. One treatment option for extended adjuvant treatment of patients with HER2+/HR+ eBC is neratinib, available in Europe for patients who completed adjuvant trastuzumab-based therapy within 1 year. The ELEANOR study is investigating the real-world use of neratinib in Germany, Austria, and Switzerland. Results from an interim analysis of the first 200 patients observed for ≥3 months are reported., Methods: The primary objective of this prospective, multicenter, observational study is to assess patient adherence to neratinib (defined as the percentage of patients taking neratinib on ≥75% prescribed days). Secondary objectives are patient characteristics and treatment outcomes., Results: At cut-off (May 2, 2022), a total of 202 patients had been observed for ≥3 months, with neratinib treatment documented for 187 patients (median age: 53.0 years; 67.9% at increased risk of disease recurrence). In total, 151 (80.7%) patients had received prior neoadjuvant treatment; of these, 82 (54.3%) patients achieved a pathologically complete response. Neratinib was initiated at a median 3.6 months after trastuzumab-based treatment, with 36.4% starting at a dose <240 mg/day. Treatment is ongoing for 46.0% of patients, with median treatment duration of 11.2 (interquartile range 0.9-12.0) months. Diarrhea was the most common adverse event (78.6% any grade, 20.3% grade ≥3); pharmacologic prophylaxis was used in 85.6% of patients., Conclusions: The pattern of anti-HER2 pretreatment observed reflected the current treatment for HER2+/HR+ eBC in Germany, Austria, and Switzerland. These interim results suggest that neratinib as an extended adjuvant is a feasible option after various anti-HER2 pretreatments and that its tolerability can be managed and improved with proactive diarrhea management., Competing Interests: Nadia Harbeck has received honoraria for lectures and/or consulting from Amgen, AstraZeneca, Daiichi Sankyo, Gilead, Lilly, MSD, Novartis, Pierre Fabre, Pfizer, Roche, Sandoz, and Seagen.
