A Phase III Study of JSKN016 Versus Treatment of Physician's Choice in Patients With Triple-Negative Breast Cancer Who Have Failed Standard of Care

Recruiting now · Phase 3

Conditions studied: Triple Negative Breast Cancer

In brief

Primary Endpoint of this Study: To compare Progression-Free Survival (PFS) (as assessed by a Blinded Independent Review Committee \[BIRC\] based on Response Evaluation Criteria in Solid Tumors \[RECIST v1.1\]) between JSKN016 and Treatment of Physician's Choice (TPC) in participants with unresectable locally advanced, recurrent, or metastatic triple-negative breast cancer (TNBC). To compare Overall Survival (OS) between JSKN016 and TPC in the treatment of unresectable locally advanced, recurrent, or metastatic TNBC.
