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
