Key clinical point: Pemetrexed + vinorelbine vs vinorelbine monotherapy led to a greater improvement in progression-free survival (PFS) outcomes and had a manageable safety profile in patients with metastatic breast cancer (BC) previously treated with anthracycline and taxane.
Major finding: The median PFS improved by 45% with pemetrexed + vinorelbine vs vinorelbine monotherapy (5.7 vs 1.6 months; hazard ratio 0.55; P = .001). Pemetrexed + vinorelbine also had a manageable safety profile in general.
Study details: Findings are from the phase 2 KCSG-BR15-17 trial including 125 patients with metastatic BC who had been treated with anthracycline and taxane previously and were randomly assigned to receive pemetrexed + vinorelbine or vinorelbine monotherapy.
Disclosures: This study was funded by a grant from the Ministry of Health and Welfare, Republic of Korea. Two authors declared receiving research funding or research drug supply from or serving in consulting or advisory roles for various sources. The other authors declared no conflicts of interest.
