Who this trial is looking for
This trial is looking for women diagnosed with early triple-negative breast cancer who have residual disease after chemotherapy. Participants will receive capecitabine and have their blood monitored for changes in tumor DNA to see if the treatment is working.
Are You a Good Fit for This Trial?

I have resolved side effects from previous treatments, except hair loss
I do not have metastatic disease
I am able to give signed informed consent
I am planning to take capecitabine for 6 months or 8 cycles
I have a negative pregnancy test if I can become pregnant
You may not be able to join if

The purpose of the study is to evaluate the use of a circulating tumor DNA (ctDNA) assay, ie, a "liquid biopsy," as a tool to identify triple-negative breast cancer (TNBC) patients who will or will not experience benefit from treatment with capecitabine. Participants will be monitored for changes in ctDNA in the blood over time received during capecitabine treatment. Results of ctDNA analysis will…
The purpose of the study is to evaluate the use of a circulating tumor DNA (ctDNA) assay, ie, a "liquid biopsy," as a tool to identify triple-negative breast cancer (TNBC) patients who will or will not experience benefit from treatment with capecitabine. Participants will be monitored for changes in ctDNA in the blood over time received during capecitabine treatment. Results of ctDNA analysis will be correlated to genetic characteristics of individual tumors. This may inform future clinical trials in which patients could receive a different treatment than capecitabine to reduce their risk of breast cancer relapse.
