Breaking New Ground | ORR of 68% and mPFS of 11.2 Months! Sacituzumab Tirumotecan Plus Immunotherapy Explores a New First-Line Treatment Strategy for la/mUC
In recent years, the combination of antibody-drug conjugates (ADCs) and immunotherapy has transformed the treatment landscape for locally advanced or metastatic urothelial carcinoma (la/mUC). However, for patients who are ineligible for cisplatin, improving tumor response rates, prolonging disease control, and maintaining treatment tolerability and quality of life remain important clinical challenges. At the 2026 European Society for Medical Oncology (ESMO) Congress, a study of first-line treatment with a regimen combining China's homegrown TROP2 ADC sacituzumab tirumotecan and immunotherapy in la/mUC was presented in a Rapid Oral session [1]. Updated data showed a confirmed objective response rate (ORR) of 68%, a median duration of response (mDOR) of 19.4 months, and a median progression-free survival (mPFS) of 11.2 months. Effective and durable tumor responses were observed regardless of TROP2 or PD-L1 expression levels, providing important evidence to inform clinical treatment decisions. Oncology Frontier – UroStream invited Professor Dingwei Ye and Professor Xiaojie Bian of Fudan University Shanghai Cancer Center to discuss the study design, efficacy and safety findings, and the development of Chinese-originated ADCs in genitourinary oncology, with the aim of providing insights for clinical practice.
