ASCO China Voice丨Professor Nanlin Li: Efficacy and Safety Data of RC48 for Neoadjuvant Therapy in HER2-Positive Breast Cancer
The 2024 American Society of Clinical Oncology (ASCO) Annual Meeting will take place in Chicago from May 31 to June 4. Led by Professor Nanlin Li from Xijing Hospital of the Air Force Medical University, a single-center, single-arm phase II clinical study focused on the efficacy and safety of the HER2-targeting antibody-drug conjugate (ADC) RC48 in the neoadjuvant treatment of HER2-positive breast cancer has disclosed its data. The study shows that although RC48 achieved lower pathological complete response rates (pCR) compared to traditional chemotherapy combined with targeted therapy, it effectively reduced tumor size rapidly, achieved moderate to significant remission, and had high safety with minimal toxicity. These findings provide a new option for neoadjuvant treatment of HER2-positive breast cancer and may expand the indications for domestically developed ADC drugs. This article reports the relevant data.
