TNBC patients who did not achieve pathological complete remission or positive lymph node after neoadjuvant chemotherapy received adjuvant treatment with study drug.

Solution: UTD1 30mg / m², once a day on days 1-5; capecitabine: 1000mg / m², days 1-14, oral, twice / day; 21 days a treatment cycle of 6-8 cycles.
