APPROVAL AT A GLANCE
This report is about:
Approval of the drug Trodelvy (sacituzumab govitecan-hizy) for treating triple-negative breast cancer ().
Why is this approval important?
triple-negative breast cancer is an aggressive type of cancer with few options for treatment beyond chemotherapy. On April 22, 2020 the U.S. Food and Drug Administration () granted accelerated approval of the drug Trodelvy for the treatment of advanced, . Trodelvy approval provides a new treatment option for metastatic breast cancer patients whose cancer has not responded or progressed after two previous lines of treatment.
Research findings:
approval of Trodelvy was based on previous research, which we reported in this XRAY review. In this clinical trial of 108 patients with triple-negative breast cancer:
- 1/3 of patients who took Trodelvy (33 percent) had their cancer shrink. Of these patients:
- More than half (55 percent) had no cancer growth for six months.
- 17 percent had no cancer growth for a year or longer.
As with most cancer medicines, Trodelvy may cause side effects. The most common side effects include:
- Nausea
- Neutropenia (abnormally low levels of white blood cells)
- Diarrhea
- Fatigue
- Anemia
- Vomiting
- Hair loss
- Constipation
- Decreased appetite
- Rash
- Abdominal pain
The label warns about the possibility of severe neutropenia or diarrhea.
What does this mean for me?
If you have been diagnosed with locally advanced or , you may want to talk to your doctor about Trodelvy.

Expert Guidelines
National Comprehensive Cancer Network (NCCN) guidelines for treatment of advanced or TNBC includes the following:
- Genetic testing:
- All people diagnosed with at any age meet guidelines for genetic counseling and testing.
The NCCN lists the following as preferred treatments for TNBC:
- therapy:
- For people with an inherited or mutation: (Lynparza) or ().
- For people without an inherited or mutation: chemotherapy.
- Second-line therapy:
- For people with but who test HER2-low: fam-trastuzumab deruxtecan-nxki (Enhertu).
- For people with who are not HER2-low: sacituzumab govitecan (Trodelvy) or chemotherapy.
- Third -ine or higher therapy:
- The NCCN recommends based on testing.
