Pembrolizumab plus Chemotherapy Prolongs Survival in Patients with Triple-Negative Breast Cancer and PD-L1 Combined Positive Score ≥10
Final results from the pivotal phase 3 KEYNOTE-355 trial showed that the addition of pembrolizumab (Keytruda) to chemotherapy resulted in a statistically significant and clinically meaningful improvement in overall survival (OS) compared with chemotherapy alone in patients with metastatic triple-negative breast cancer (TNBC) whose tumors expressed PD-L1 with a combined positive score (CPS) ≥10.
Trastuzumab Deruxtecan Beats Trastuzumab Emtansine as Second-Line Therapy for HER2-Positive Metastatic Breast Cancer
Second-line therapy with trastuzumab deruxtecan (Enhertu; T-DXd) extended progression-free survival (PFS) and improved objective response rate (ORR) versus trastuzumab emtansine (Kadcyla; T-DM1) in women with HER2-positive metastatic breast cancer, including those with stable brain metastasis at baseline, according to a subgroup analysis of a phase 3 clinical trial.
Dr Matthew Goetz believes that, as more mature data come into existence, the demonstration of a survival advantage will guide more patients with metastatic breast cancer to try CDK4/6 inhibitors plus aromatase inhibitors instead of chemotherapy.
CDK6 Could Be a Key Factor for Efficacy of CDK4/6 Inhibitors and the Hormone Sensitivity Following Acquired Resistance
An underlying mechanism of combined endocrine therapy and CDK4/6 inhibitor resistance in hormone receptor–positive breast cancer is senescent escape, and 2 novel therapeutic strategies have been identified for this disease, including MDM2 inhibition and CDK2 activation.
Loss of Mismatch Repair Predicts Resistance to Endocrine Therapy and Sensitivity to CDK4/6 Inhibitors in ER-Positive Breast Cancer
Although there are currently no biomarkers to guide the use of CDK4/6 inhibitors for estrogen receptor (ER)-positive breast cancer, markers of mismatch repair dysregulation could identify patients in whom CDK4/6 inhibition may prevent disease recurrence most effectively.
The phase 1b trial of the insulin-like growth factor ligand-neutralizing antibody xentuzumab and the CDK4/6 inhibitor abemaciclib, plus endocrine therapy, is designed to evaluate safety, tolerability, and preliminary efficacy in patients with locally advanced or metastatic hormone receptor (HR)-positive/HER2-negative breast cancer.
