Real-World Study Supports Everolimus + Exemestane as HR+/HER2− BC Treatment

Key clinical point: Everolimus + exemestane demonstrated good efficacy and had a manageable safety profile in postmenopausal women with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2−) breast cancer (BC).

Major finding: Everolimus + exemestane led to a median progression-free survival (PFS) of 6.6 months (95% CI 6.3-7.0 months). PFS was more favorable among patients with a greater vs lower body mass index (≥25 vs 20 to <25 kg/m²; P < .0001); however, the survival outcomes were worse among patients with vs without visceral metastases (hazard ratio 1.417; P < .0001). Stomatitis (42.6%) and fatigue (19.8%) were the most frequent adverse events.

Study details: Findings are from a prospective, non-interventional study including 2074 postmenopausal women with HR+/HER2− advanced BC who received everolimus + exemestane.

Disclosures: This study was funded by Novartis Deutschland GmbH, Germany. Two authors declared being employees of or holding stocks in Novartis. Some authors declared receiving honoraria or personal fees or having other ties with Novartis and various other sources. Eight authors declared no conflicts of interest.
