About this trial

This study is a multi-center observational real-world study, with a total of 500 patients planned to be enrolled. This study is divided into two cohorts: the triple-negative breast cancer (TNBC) cohort and the hormone receptor-positive/human epidermal growth factor receptor 2-negative breast cancer (HR+/ HER2-BC) cohort. The aim of this study is to assess the efficacy and safety of Sacituzumab Tirumotecan (SKB264) monotherapy or combination therapy in patients with unresectable locally advanced, recurrent or metastatic HER2-negative breast cancer in the real-world setting.

Time from initiation of SKB264 monotherapy or combination therapy to start of next treatment, assessed up to 24 weeks.

Secondary outcomes

1

Real world progression free survival (rwPFS) of SKB264 monotherapy or combination therapy

Time frame
Time from initiation of SKB264 monotherapy or combination therapy to the first documented evidence of progression or death, whichever came first, assessed up to 24 weeks.
2

Duration of treatment (DOT) of SKB264 monotherapy or combination therapy

Time frame
Time from initiation of SKB264 monotherapy or combination therapy to its discontinuation, assessed up to 24 weeks.
3

Real world objective response rate (rwORR) of SKB264 monotherapy or combination therapy

Time frame
The proportion of patients who had a complete or partial response documented by imaging reports or by assessment of treating physician during the study treatment, which is approximately up to 24 weeks from the initiation of the study treatment.
4
