【Ingredients】
Active ingredient: Gosartuzumab
Active ingredient source: Gosartuzumab is an antibody-drug conjugate (ADC) consisting of an antibody targeting trophoblast cell surface antigen-2 (Trop-2) and a topoisomerase inhibitor, including the following three components:
Humanized monoclonal antibody hRS7 IgG1κ (also known as sacituzumab), which can bind to the trophoblast cell surface antigen (Trop-2); Drug SN-38, a topoisomerase inhibitor; A hydrolyzable linker (called CL2A) that connects the humanized monoclonal antibody and SN-38.
The recombinant monoclonal antibody is produced by mammalian cells, while the small molecule components SN-38 and CL2A are produced by chemical synthesis. The average drug/antibody ratio of gosartuzumab is 7-8.

[Properties]
Gosartuzumab for injection is a preservative-free, off-white to pale yellow, sterile lyophilized powder for intravenous infusion.
[Indications]
This product is used for adult patients with unresectable locally advanced or metastatic triple-negative breast cancer who have received at least 2 systemic therapies (at least 1 of which was for metastatic disease).
