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.

Giuseppe Curigliano, MD, PhD, of Istituto Europeo di Oncologia, IRCCS, University of Milano, discusses patient-reported outcomes from the phase III EMBER-3 trial, which investigated treatment with imlunestrant, investigator’s choice of standard endocrine therapy, or imlunestrant plus abemaciclib in patients with ER-positive, HER2-negative advanced breast cancer (Abstract 1001).

Sameek Roychowdhury, MD, PhD, of the Arthur G. James Cancer Hospital and Richard J. Solove Research Institute at The Ohio State University Wexner Medical Center, discusses a recently opened telemedicine clinical trial of pemigatinib in patients with advanced or metastatic FGFR-mutated pancreatic cancer, and the germination of a new initiative, TNT Cancer, which focuses on leveraging telemedicine to bring trials nationwide.

Frank A. Sinicrope, MD, of Mayo Clinic Rochester, reviews findings from the randomized Alliance A021502/ATOMIC trial, which studied standard chemotherapy alone or combined with atezolizumab as adjuvant therapy for patients with stage III DNA mismatch repair–deficient (dMMR) colon cancer (LBA1).

Yelena Y. Janjigian, MD, of Memorial Sloan Kettering Cancer Center, presents event-free survival data from the phase III MATTERHORN trial of the PD-L1 inhibitor durvalumab plus FLOT (fluorouracil, leucovorin, oxaliplatin and docetaxel chemotherapy) in patients with resectable gastric or gastroesophageal junction (GEJ) cancer (LBA5).

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).
