Cynthia X. Ma, MD, PhD, on Metastatic Breast Cancer: Early Results on Copanlisib, Fulvestrant, and Abemaciclib
2023 SABCS
Cynthia X. Ma, MD, PhD, of Washington University School of Medicine in St. Louis, discusses phase I findings showing the safety and tolerability of copanlisib and fulvestrant in combination with continuous or intermittent abemaciclib in patients with estrogen receptor–positive, HER2-negative metastatic breast cancer. Preliminary antitumor activity, which was observed, will be further examined in the phase II trial (ClinicalTrials.gov identifier NCT03939897) (Abstract PS17-06).

Sherene Loi, MD, PhD, of Australia’s Peter McCallum Cancer Centre, discusses an exploratory analysis of CheckMate 7FL which showed that patients with PD-L1–positive, high-risk, estrogen receptor–positive, HER2-negative primary breast cancer may achieve substantial pathologic complete response rates with the addition of nivolumab to neoadjuvant chemotherapy (Abstract GS01-01).

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).

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).

Senthil Damodaran, MD, PhD, of The University of Texas MD Anderson Cancer Center, discusses final results from the FOENIX-MBC2 study of the efficacy and safety of futibatinib in patients with locally advanced or metastatic hormone receptor–positive, HER2-negative breast cancer harboring high-level FGFR1 gene amplification. Futibatinib plus fulvestrant showed antitumor activity in those whose disease had progressed on prior CDK4/6 inhibitors (Abstract RF01-04).
