Barbara Pistilli, MD, on HR+, HER2– Advanced Breast Cancer: Update on Capivasertib Plus a CDK4/6 Inhibitor and Fulvestrant
2023 SABCS
Barbara Pistilli, MD, of France’s Gustave Roussy, discusses a phase Ib analysis from the CAPItello-292 study, which showed capivasertib plus palbociclib plus fulvestrant was tolerable at all dose levels in heavily pretreated patients with hormone receptor–positive, HER2-negative advanced breast cancer. As data collection continues, evidence of clinical activity has been observed in patients treated with the recommended phase III dose (Abstract PS12-09).
Aditya Bardia, MD, MPH, of Massachusetts General Hospital Cancer Center, discusses updated phase III results from the TROPION-Breast01 study. The data showed an improvement in progression-free survival with datopotamab deruxtecan compared with investigator’s choice of chemotherapy across all subgroups of patients with inoperable or metastatic hormone receptor–positive, HER2-negative breast cancer who have received one to two prior lines of chemotherapy (Abstract GS02-01).

Sara A. Hurvitz, MD, of Fred Hutchinson Cancer Research Center, University of Washington, discusses phase III findings of the HER2CLIMB-02 study, which showed the combination of tucatinib and trastuzumab emtansine improved progression-free survival in patients with previously treated, HER2-positive, locally advanced or metastatic breast cancer (including those with brain metastases) (Abstract GS01-10).

Sherene Loi, MD, PhD, of Australia’s Peter McCallum Cancer Centre, discusses recent data showing that for patients with stage I/II triple-negative breast cancer, 12 weeks of a neoadjuvant nonanthracycline chemotherapy regimen with nivolumab may be efficacious with either concurrent or lead-in nivolumab. Those with immune-enriched tumors had high pathologic complete response rates, identifying a subpopulation for whom a 12-week anthracycline-free chemotherapy regimen with nivolumab may be appropriate (Abstract LBO1-03).

Daniel G. Stover, MD, of The Ohio State University Comprehensive Cancer Center, discusses a biomarker analysis from the PALLAS adjuvant trial, which compared 2 years of the CDK4/6 inhibitor palbociclib with endocrine therapy vs endocrine therapy alone, as adjuvant treatment for patients with stage II–III hormone receptor–positive, HER2-negative breast cancer. The genomic subtype PAM50 was defined in the protocol of the PALLAS trial as the primary biomarker for analysis of prediction and prognosis (Abstract GS03-07).

Aditya Bardia, MD, MPH, of Massachusetts General Hospital Cancer Center, discusses phase III findings from the KEYNOTE-756 study, which showed that adding pembrolizumab to chemotherapy increases the pathologic complete response rate and lowers the residual cancer burden in patients with early-stage, high-risk ER-positive or HER2-negative breast cancer (Abstract GS01-02).
