ESMO Investigator Insights | Professor Qingyuan Zhang: Robust Clinical Evidence Demonstrates the Strength of Iza-bren, Ushering in a New Era of Breast Cancer Treatment
The European Society for Medical Oncology (ESMO) Congress is one of the most influential academic events in global oncology, where the presentation of each major study has the potential to reshape the clinical treatment landscape. Iza-bren (伦康依隆妥单抗), a globally pioneering, first-in-class bispecific antibody–drug conjugate (ADC) and the first of its kind to receive regulatory approval worldwide, has demonstrated significant clinical impact. At this year's congress, the interim analysis results of its pivotal Phase III PANKU-Breast01 study were presented as a late-breaking abstract (LBA). The study evaluated patients with unresectable locally advanced or metastatic HR-positive/HER2-negative breast cancer who had received prior endocrine therapy and one to two lines of chemotherapy. The results were also published simultaneously in The Lancet (impact factor: 109), making iza-bren the first innovative Chinese drug in the field of breast cancer to be published in the journal's main edition in its 200-year history.
