Is Trodelvy (sacituzumab govitecan-hziy) a chemotherapy?

Trodelvy is an immune targeted therapy medicine which consists of a monoclonal antibody (sacituzumab) that can help the immune system recognize and fight the cancer. Trodelvy is a so-called antibody-drug conjugate (ADC): a linking compound attaches (conjugates) sacituzumab to the SN-38 chemotherapy.^1,4

What is Sacituzumab Govitecan HZIY?

Sacituzumab Govitecan is a Trop-2-directed antibody-drug conjugate (ADC). Sacituzumab Govitecan is made up of 3 parts:⁴

• Sacituzumab, a Trop-2-recognizing antibody, which is a type of protein designed to recognise and attach to the Trop2 antigen present on cancer cells.
• SN-38, a topoisomerase I inhibitor (chemotherapy), which damages the tumor cell’s DNA and inhibits further DNA replication.
• A compound that conjugates (links) these two parts together.

How does Trodelvy (sacituzumab govitecan-hziy) work?

When sacituzumab binds to Trop-2 on the cancer cell, the drug is taken up by the cell and the linker is broken. This causes the release of SN-38, which will then destroy the Trop-2-positive cancer cells.^1,4

Who makes Trodelvy sacituzumab govitecan-hziy)?

Trodelvy is made by Immunomedics. Immunomedics is specialised in next-generation antibody-drug conjugate (ADC) technology, and they aim to help patients with hard-to-treat cancers. Trodelvy is the company's lead ADC.
