Breakthrough in Bladder Cancer Treatment! Lin Tianxin and Chen Xu’s Team at Sun Yat-sen University First to Demonstrate Safety and Preliminary Efficacy of Intravesical Disitamab Vedotin in HER2-Positive High-Risk Non-Muscle-Invasive Bladder Cancer
A research team led by Professor Lin Tianxin and Professor Chen Xu from the Sun Yat-sen Memorial Hospital of Sun Yat-sen University has published clinical trial results in the prestigious journal MedComm, titled “Intravesical Disitamab Vedotin (RC48) for HER2-Expressing High-Risk Non-Muscle-Invasive Bladder Cancer: A Single-Arm, Dose–Escalation Phase I Trial Study.” This marks the world’s first clinical study to evaluate the intravesical administration of the HER2-targeted antibody–drug conjugate (ADC) disitamab vedotin (RC48) in patients with HER2-positive high-risk non-muscle-invasive bladder cancer (HR-NMIBC). The study offers a novel bladder-sparing strategy for patients who are unresponsive or intolerant to Bacillus Calmette-Guérin (BCG) therapy.
