Abstract
Purpose Metronomic chemotherapy (MCT) is an increasingly used treatment option in hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) advanced/metastatic breast cancer (MBC) after failure of endocrine-based therapies. Methods VinoMetro was a multicentre, open-label, single-arm, phase II study of metronomic oral vinorelbine (VRL;30 mg/day) as a first-line chemotherapy (CT) in patients with HR+/HER2- MBC after endocrine failure. The primary endpoint was the clinical benefit rate (CBR) at 24 weeks. Results Between January 2017 and April 2019, nine patients were enrolled. The CBR was 22.2% (90% confidence interval [CI] 4.1-55.0), p = 0.211. The median progression-free survival (PFS) was 12.0 weeks (95% CI 11.3-12.7). Grade 3-4 adverse events (AEs) occurred in 22.2% of patients. One patient died of febrile neutropenia. Conclusion VinoMetro (AGO-B-046) was closed early after nine patients and occurrence of one grade 5 toxicity in agreement with the lead institutional review board (IRB). Metronomic dosing of oral VRL in HR+/HER2- MBC as first-line CT after failure of endocrine therapies showed only limited benefit in this population.
