About this trial

The EXActDNA-003 study will prospectively enroll participants who are planning to undergo chemotherapy for high-risk, early breast cancer, who are willing to provide tissue and blood specimens for circulating tumor DNA (ctDNA) analysis.

Participants will be followed for up to 5.5 years.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

The participant or a legally authorized representative must provide study-specific informed consent prior to study entry.

The participant must be ≥ 18 years of age.

ECOG performance status 0 or 1.

Histologically confirmed invasive carcinoma of the breast.

Disqualifiers

Definitive clinical or radiologic evidence of metastatic disease.

Initiated neoadjuvant therapy for current breast cancer diagnosis.

Synchronous diagnosis of another invasive cancer, other than this breast cancer, except for non-melanoma skin cancers.

Completed all therapy (including endocrine therapy) <5 years ago for any previous invasive solid organ malignancy (with exception of non-melanoma skin cancers) including prior breast cancer. Individuals with a prior history of noninvasive (in situ) carcinomas may participate if they have received definitive treatment.
