The frontline combination of ribociclib and letrozole significantly prolonged overall survival over letrozole alone in a subset of patients with hormone receptor–positive, HER2-negative advanced breast cancer who had de novo metastatic disease or late recurrence from neoadjuvant therapy, according to data from an exploratory analysis of the phase 3 MONALEESA-2 trial.
Fam-trastuzumab deruxtecan-nxki was associated with better efficacy outcomes compared with treatment of physician’s choice in patients with HER2-low, estrogen receptor-low metastatic breast cancer, according to findings from a subgroup analysis of the phase 3 DESTINY-Breast04 study.
Preoperative treatment with atezolizumab, epirubicin, trastuzumab, and pertuzumab led to improved rates of pathologic complete response and decreased residual cancer burden compared with trastuzumab, pertuzumab, and chemotherapy alone in patients with early-stage HER2-positive breast cancer, according to findings from the randomized phase 2 ATHENE trial.
The addition of atezolizumab to neoadjuvant chemotherapy generated numerical improvements in event-free survival, disease-free survival, and overall survival compared with chemotherapy plus placebo in patients with early-stage triple-negative breast cancer.
Sacituzumab govitecan-hziy produced comparable efficacy outcomes for patients with metastatic triple-negative breast cancer who had a higher incidence of grade 2 or 3 diarrhea and neutropenia vs patients in the overall population, according to a post hoc analysis of the phase 3 ASCENT trial presented at the 2023 ESMO Breast Cancer Annual Congress.
