Oral Etoposide Combined With Anlotinib in Advanced Triple Negative Breast Cancer

Oral Etoposide Combined With Anlotinib in Advanced Triple Negative Breast Cancer

The hypothesis of this study is to discover if the oral Etoposide plus Anlotinib can shrink or slow the growth of pretreated advanced TNBC.

It is a single-arm, multicenter phase II clinical study of oral etoposide combined with antinib in the treatment of recurrent or metastatic triple-negative breast cancer

It is a single-arm, multicenter phase II clinical study of oral etoposide combined with antinib in the treatment of recurrent or metastatic triple-negative breast cancer.

The hypothesis of this study is to discover if the oral Etoposide plus Anlotinib can shrink or slow the growth of pretreated advanced TNBC.
