Senthil Damodaran, MD, PhD, on Locally Advanced or Metastatic Breast Cancer: Phase II Results on Futibatinib
2023 SABCS
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).

Reshma Jagsi, MD, DPhil, of Emory University Winship Cancer Institute, discusses the IDEA trial of endocrine therapy without radiotherapy after breast-conserving surgery for postmenopausal patients between the ages of 50 and 69 with stage I breast cancer. The regimen demonstrated a low risk of relapse in this population, with a genomic assay used in combination with classic clinical and biological features for treatment selection (Abstract GS02-08).

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).

Hope S. Rugo, MD, of the University of California, San Francisco Helen Diller Family Comprehensive Cancer Center, discusses patient-reported outcomes from the phase III CAPItello-291 study; the trial centered on adding capivasertib to fulvestrant in patients with aromatase inhibitor–resistant, hormone receptor–positive, HER2-negative advanced breast cancer. Patients treated with capivasertib and fulvestrant reported maintained health-related quality of life longer than those treated with placebo and fulvestrant (Abstract PS02-02).

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).

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).
