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).

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).
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).

Amy Tiersten, MD, of the Icahn School of Medicine at Mount Sinai and Tisch Cancer Institute, discusses findings from the ASPIRE trial, which showed the combination of anastrozole, palbociclib, trastuzumab, and pertuzumab in the front-line setting was well tolerated and effective, with a clinical benefit rate of 97% in patients with previously untreated hormone receptor–positive, HER2-positive metastatic breast cancer (Abstract RF02-01).

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).

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).
