About Triple-Negative Breast Cancer (TNBC)

TNBC is an aggressive disease with an annual incidence estimated to be about 40,000 people, approximately 15% of all breast cancer types, in the United States alone. The incidence rate is higher among younger women and highest among non-Hispanic black and Hispanic women. TNBC tumors do not have sufficient estrogen, progesterone or HER2 receptor expression to indicate the use of hormonal or HER2-directed therapy. There is currently no standard-of-care chemotherapy for people with relapsed/refractory mTNBC. An overall response rate of about 10% and median progression-free survival of 2-3 months have recently been reported in late-stage mTNBC using single-agent chemotherapy.1,2

About Sacituzumab Govitecan

Sacituzumab govitecan, Immunomedics’ most advanced product candidate, is a novel, first-in-class ADC delivering SN-38, a potent topoisomerase I inhibitor, directly to tumor cells by targeting the Trop-2 antigen expressed by many solid cancers. It is currently under review by the U.S. Food and Drug Administration for accelerated approval as a treatment of patients with mTNBC who have received at least two prior therapies for metastatic disease. If approved, sacituzumab govitecan would be the first and only ADC approved for the treatment of mTNBC.
