MONARCH plus: abemaciclib plus endocrine therapy in women with HR+/HER2- advanced breast cancer: the multinational randomized phase III study.

Aim: To compare the efficacy, safety, and tolerability of abemaciclib plus endocrine therapy (ET) ET alone in postmenopausal women with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer (ABC) from China, Brazil, India, and South Africa.

Methods: This randomized, double-blind, phase III study was conducted between 9 December 2016 and 29 March 2019. Postmenopausal women with HR-positive, HER2-negative ABC with no prior systemic therapy in an advanced setting (cohort A) or progression on prior ET (cohort B) received abemaciclib (150 mg twice daily) or placebo plus: anastrozole (1 mg/day) or letrozole (2.

Consistent efficacy and safety of gemcitabine-paclitaxel in patients with metastatic breast cancer: a retrospective comparison of East Asian and global studies.

Aims: The incidence of breast cancer in China is increasing at a rate greater than the global average. For treatment of metastatic breast cancer, a phase 3 trial of 529 patients (study JHQG) found that the combination of gemcitabine, a cytotoxic nucleoside analog, and paclitaxel, a taxane, significantly improved both overall and progression-free survival compared with paclitaxel monotherapy. As ethnic differences in the safety and efficacy of some anticancer therapies have been reported, this review provides oncologists treating East Asian patients with an evidence base to extrapolate results of the predominately Caucasian phase 3 JHQG study to their patients.

Lapatinib plus capecitabine in treating HER2-positive advanced breast cancer: efficacy, safety, and biomarker results from Chinese patients.

Overexpression of human epidermal growth factor receptor-2 (HER2) in metastatic breast cancer (MBC) is associated with poor prognosis. This single-arm open-label trial (EGF109491; NCT00508274) was designed to confirm the efficacy and safety of lapatinib in combination with capecitabine in 52 heavily pretreated Chinese patients with HER2-positive MBC. The primary endpoint was clinical benefit rate (CBR).
