Shifting from Passive to Proactive: Final PFS2 Data from the SERENA-6 Study Released; Camizestrant Switch Therapy Significantly Extends Survival Benefits for ESR1-Mutant Patients
At a recent international oncology symposium, Professor François-Clément Bidard from Institut Curie shared the updated results from the third data cut-off (DCO3) of the Phase III SERENA-6 study. The study focuses on patients with HR+/HER2- advanced breast cancer (ABC). During first-line treatment with an aromatase inhibitor (AI) combined with a CDK4/6 inhibitor (CDK4/6i), once a new-onset ESR1 mutation is detected via circulating tumor DNA (ctDNA) monitoring, the AI is immediately switched to Camizestrant, a novel oral selective estrogen receptor degrader (SERD), to assess clinical benefit. This report highlights key secondary endpoints—the final progression-free survival 2 (PFS2) and core data such as ctDNA kinetics analysis.
