Hope S. Rugo, MD, FASCO, and Rebecca Alexandra Dent, MD, FASCO, on Breast Cancer Data Highlights: Sequencing of Endocrine Therapy
2025 ASCO Annual Meeting
Hope S. Rugo, MD, FASCO, of City of Hope, and Rebecca Alexandra Dent, MD, FASCO, of National Cancer Centre Singapore, review the results of a biomarker analysis of the DESTINY-Breast06 trial, which evaluated trastuzumab deruxtecan after endocrine therapy in patients with metastatic breast cancer (Abstract 1013). They also discuss findings from the SERENA-6 and EMBER-3 trials, also presented at ASCO 2025, and what all this new data means for the sequencing of endocrine therapy in patients with breast cancer.

Angela R. Bradbury, MD, of the University of Pennsylvania, presents findings from the eREACH trial—a randomized study of an eHEALTH delivery alternative for cancer genetic testing for hereditary predisposition in patients with metastatic cancers (Abstract 10502).

Karen Eubanks Jackson, Founder and Chief Executive Officer of Sisters Network Inc. and recipient of the 2025 ASCO Patient Advocate Award, discusses her 30-year-long effort to support patients with breast cancer in the Black community. Sisters Network is focused on raising awareness of early screening for breast cancer, providing financial assistance, and addressing the disparities Black women face in breast cancer care and outcomes.

Erika Hamilton, MD, Director, Breast Cancer Research at Sarah Cannon Research Institute, reviews data from the global, randomized, phase III VERITAC-2 study, which compared vepdegestrant, an oral PROTAC (PROteolysis TArgeting Chimera) estrogen receptor degrader, to fulvestrant among patients with ER-positive HER2-negative advanced breast cancer. Vepdegestrant is the first PROTAC to be evaluated in a phase III trial (Abstract LBA1000).

Martin Reck, MD, PhD, of LungenClinic Grosshansdorf, Germany, discusses data from the phase III AEGEAN trial that studied perioperative durvalumab and neoadjuvant chemotherapy. Patients who were MRD-positive after surgery had significantly worse disease-free survival compared to MRD-negative patients. In addition, mutations in KEAP1 and KMT2C were associated with MRD positivity and reduced benefit from the regimen, identifying a small high-risk subgroup with poor prognosis (Abstract 8009).

Mafalda Oliveira, MD, PhD, of Vall d’Hebron University Hospital and Vall d’Hebron Institute of Oncology, discusses findings on the incidence and management of hyperglycemia in a subset of patients with prediabetes and/or obesity included in the phase I trial of inavolisib alone and in combination with endocrine therapy with or without palbociclib for PIK3CA-mutated, hormone receptor–positive, HER2-negative locally advanced/metastatic breast cancer (Abstract 1004).
