CtDNA Based MRD Testing for NAC Monitoring in TNBC

Sponsored by Personalis Inc.

About this study

A prospective, multicenter, observational study to evaluate the correlation of Molecular Residual Disease (MRD) detection using circulating tumor DNA guided test to pathological complete response (pCR) after neoadjuvant chemotherapy (NAC) in stage I-III triple negative breast cancer (TNBC). Results from this study aim to improve MRD detection and disease outcomes for future patients.

NeXT Personal CTA (Clinical Trial Assay) is a patient-specific, tumor-informed device which allows for detection of MRD from cfDNA. By using next generation sequencing technology, whole genome sequencing (WGS) is conducted from DNA derived from patient tumor and normal samples. A tumor informed personalized panel is then constructed that uses only a selection of DNA targets from the WGS by applying bioinformatic filters. The targeted personalized panel is then sequenced using NGS and DNA derived from cfDNA from plasma samples. The data from the cfDNA NGS are then further analyzed using bioinformatics filters to report the MRD status.

Only the research team can confirm whether you qualify. The intake questionnaire is the best way to find out.

Completing a questionnaire on Clinably does not enroll you in a clinical trial or confirm your eligibility. Only the research team can determine whether you qualify to participate. These results are based on the information you provide and are intended to help you start a conversation with the research team.
