Erika Hamilton, MD, on ER-Positive HER2-Negative Advanced Breast Cancer: Vepdegestrant vs Fulvestrant
2025 ASCO Annual Meeting
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).

Gerhardt Attard, MD, PhD, of the Cancer Institute, University College London, presents findings from the phase III AMPLITUDE trial, which looked at the combination of niraparib and abiraterone acetate plus prednisone for patients with metastatic castration-sensitive prostate cancer with alterations in homologous recombination repair (HRR) genes (Abstract LBA5006).

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.

Elena Elez, MD, PhD, of Vall d’Hebron Institute of Oncology, presents updated overall survival data as well as progression-free survival data from the BREAKWATER trial of the first-line use of encorafenib, cetuximab, and mFOLFOX6 in BRAF V600E–mutant metastatic colorectal cancer (LBA3500).

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).

Nicholas C. Turner, MD, PhD, of the Royal Marsden Hospital, presents findings from the phase III, double-blind ctDNA-guided SERENA-6 trial, which evaluated the combination of camizestrant plus a CDK4/6 inhibitor to treat emergent ESR1 mutations during first-line endocrine therapy for patients with HR-positive, HER2-negative advanced breast cancer (LBA4).
