The investigational oral selective estrogen receptor degrader elacestrant significantly decreased the risk of death or disease progression and increased progression-free survival compared with standard-of-care endocrine therapy for postmenopausal patients with estrogen receptor (ER)-positive/HER2-negative metastatic breast cancers that progressed on prior endocrine and targeted therapies, according to results from the phase III EMERALD trial.
The phase III persevERA Breast Cancer study, evaluating investigational giredestrant in combination with palbociclib for people with oestrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative, locally advanced or metastatic breast cancer, did not meet its primary objective of a statistically significant improvement in progression-free survival in the intent-to-treat population versus letrozole plus palbociclib, but a numerical improvement was observed.
