Suneel Kamath, MD, of Cleveland Clinic, discusses a study that found tissue tumor mutation burden (TMB) was a stronger predictor of immunotherapy outcomes than blood-based circulating tumor DNA testing, with high tissue TMB associated with a longer time to treatment failure (Abstract 2580).
Elena Elimova, MD, Princess Margaret Cancer Centre, discusses the efficacy in PD-L1 subgroups of zanidatamab plus chemotherapy with or without tislelizumab as a first-line regimen for HER2-positive locally advanced or metastatic gastroesophageal adenocarcinoma (Abstract 4010).
Julie R. Gralow, MD, FACP, FASCO, Chief Medical Officer and Executive Vice President of ASCO, provides an overview of the highlights of this year’s meeting, including practice-changing data included in the Plenary Session.
Antonio Llombart-Cussac, MD, PhD, of Medica Scientia Innovation Research (MEDSIR), discusses the ongoing ADELA study, a double-blind, placebo-controlled, randomized phase III trial of elacestrant plus everolimus vs elacestrant plus placebo in patients with estrogen receptor (ER)-positive HER2-negative advanced breast cancer with ESR1-mutated tumors who experienced disease progression on endocrine therapy plus CDK4/6 inhibition (Abstract TPS1154).
ClinicalTrials.gov identifier: NCT06382948
Robert C. Stein, PhD, MBBChir, FRCP, of the National Institute for Health Research University College London Hospitals Biomedical Research Centre, discusses the first results from the phase III randomized OPTIMA trial, which is comparing chemotherapy decisions made with the Prosigna (PAM50) gene expression test with standard treatment with estrogen receptor (ER)-positive, HER2-negative early breast cancer (Abstract 500).
Jame Abraham, MD, FACP, of Cleveland Clinic, provides an update on the DESTINY-Breast05 trial, which is an ongoing phase III trial investigating postneoadjuvant trastuzumab deruxtecan (T-DXd) as compared with trastuzumab emtansine (T-DM1) in patients with HER2-positive breast cancer with residual invasive disease and node-positive disease at surgery or inoperable disease at diagnosis. Dr. Abraham makes special note of rates of interstitial lung disease seen in the trial and methods of management.
