The triplet combination of zotatifin, abemaciclib, and fulvestrant demonstrated a confirmed overall response rate of 21% in heavily pretreated patients with estrogen receptor–positive metastatic breast cancer.

Findings from a subgroup analysis of the phase 3 EMERALD trial presented during the 2023 ASCO Annual Meeting demonstrated elacestrant elicited prolonged progression-free survival compared with standard-of-care therapy for patients with estrogen receptor-positive, HER2-negative non-detected ESR1 mutated breast cancer who experienced disease progression within 6 months of CDK4/6 inhibitor treatment plus endocrine therapy.

A clinically meaningful absolute risk reduction in invasive disease-free survival and distant relapse-free survival with abemaciclib plus endocrine therapy was maintained in patients with hormone receptor–positive, HER2-negative, high-risk early breast cancer regardless of age.

Colin E. Champ, MD, discusses the importance of considering the use of radiation therapy for patients with breast cancer and details ongoing research into this arena.

Treatment with ribociclib plus endocrine therapy led to a statistically and clinically meaningful improvement in invasive disease-free survival among patients with hormone receptor–positive/HER2-negative early breast cancer compared with endocrine therapy alone, meeting the primary end point of the phase 3 NATALEE trial.

Yuan Yuan, MD, PhD, discusses the importance of clinical trial participation and enrollment in patients with breast cancer.

Higher baseline HER3-positive circulating tumor cell count at baseline and reduction following treatment initiation was associated with a higher likelihood of deriving an early response with patritumab deruxtecan in patients with hormone receptor–positive or HER2-low advanced breast cancer.
