Chicago, IL—The addition of the CDK4/6 inhibitor ribociclib (Kisqali) to endocrine therapy significantly improved invasive disease-free survival in patients with hormone receptor (HR)-positive, HER2-negative, early breast cancer, according to interim results from the phase 3 NATALEE trial, which were presented at the 2023 American Society of Clinical Oncology Annual Meeting.

Young women with early-stage, hormone receptor–positive breast cancer attempting to become pregnant can safely pause endocrine therapy and resume it later, according to initial results from the international POSITIVE trial. Read More ›

Patients with hormone receptor (HR)-positive, HER2-negative advanced breast cancer, including those with visceral crises, treated with the CDK4/6 inhibitor ribociclib (Kisqali) plus endocrine therapy had a significantly longer progression-free survival (PFS) and fewer adverse events (AEs) compared with those treated with combination chemotherapy, according to results from the phase 2 RIGHT Choice trial.

Using circulating tumor cell (CTC) count to guide the choice of first-line treatment—chemotherapy or endocrine therapy—improved overall survival (OS) compared with investigator’s choice of treatment for patients with metastatic, estrogen receptor (ER)-positive, HER2-negative breast cancer, according to results from the STIC CTC trial, which were discussed at the 2022 San Antonio Breast Cancer Symposium (SABCS) by François-Clément Bidard, MD, PhD, Co-Coordinator, Breast Cancer Research, Institut Curie, Paris, France, and Professor, Medicine, Department of Medical Oncology, Institut Curie and Université de Versailles Saint-Quentin-en-Yvelines, France.

In patients with hormone receptor (HR)-positive, HER2-low or -negative, locally advanced or metastatic breast cancer resistant to aromatase inhibitors, the addition of the investigational first-in-class AKT inhibitor capivasertib (AZD5363) to fulvestrant (Faslodex) led to a statistically significant and clinically meaningful improvement in progression-free survival (PFS) compared with placebo plus fulvestrant. The PFS benefit observed with capivasertib was even greater in a subset of patients with an AKT pathway alteration. Read More ›

Endocrine therapy after breast-conserving surgery may be the only treatment needed in patients aged ≥55 years with low-grade luminal type A breast cancer, sparing them radiation therapy, including its side effects, financial burden, and inconvenience, according to findings from the single-arm LUMINA clinical trial reported at the 2022 American Society of Clinical Oncology Annual Meeting.

Several baseline factors were associated with an increased risk for early treatment discontinuation in the phase 3 monarchE clinical trial, which assessed adjuvant abemaciclib (Verzenio) in patients with hormone receptor–positive, HER2-negative early breast cancer, according to findings from a multivariate analysis presented during the 2022 American Society of Clinical Oncology Annual Meeting.

Targeting HER2 with the antibody–drug conjugate fam-trastuzumab deruxtecan-nxki (Enhertu; T-DXd) provided clinically meaningful benefits for patients with HER2-low metastatic breast cancer, according to findings presented at the 2022 American Society of Clinical Oncology Annual Meeting.

The investigational oral selective estrogen receptor degrader (SERD) elacestrant (RAD1901) significantly reduced the risk for death or disease progression and improved progression-free survival (PFS) compared with standard-of-care (SOC) endocrine therapy in patients with estrogen receptor (ER)-positive, HER2-negative metastatic breast cancer who had progressed on prior endocrine and targeted therapies, according to results of the phase 3 EMERALD clinical trial.

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.
