Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To evaluate the efficacy and safety of Disitamab vedotin (RC48-ADC) as salvage treatment in patients with HER2-low advanced breast cancer who have received up to one previous chemotherapy for recurrent or metastatic disease without previous use of antibody-drug conjugate.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Subjects with HER2-low advanced breast cancer were treated with Disitamab vedotin as salvage treatment. ORR, PFS, OS and AE were assessed during the trial. HER2-low status is defined as IHC1+ or IHC2+ with negative FISH test.
