PREDICT-RD: ctDNA Surveillance in TNBC With Residual Disease
(PREDICT-RD)
What this study is about
This is a Phase II, interventional, forward-looking, single-treatment group$1, multi-center study that will enroll patients with stage II/III triple negative breast cancer (TNBC) who have residual cancer burden (RCB) II/III after conventional neoadjuvant chemo-immunotherapy followed by surgery.
View original scientific description
This is a Phase II, interventional, prospective, single-arm, multi-center study that will enroll patients with stage II/III triple negative breast cancer (TNBC) who have residual cancer burden (RCB) II/III after conventional neoadjuvant chemo-immunotherapy followed by surgery. Technological advances in ctDNA assays have improved both the sensitivity and reliability of molecular residual disease (MRD) detection to enable real-time measurement with clinical-grade assays. The primary objective of this study will be to evaluate ctDNA-based MRD status in high-risk, early-stage TNBC patients by defining the proportion of TNBC patients with MRD-only recurrence (ctDNA positive without radiographically measurable recurrence) during post-surgery surveillance. The secondary objectives will evaluate the safety, preliminary efficacy, and survival outcomes of using Dato-DXd in participants with MRD-only TNBC. Dato-DXd is an investigational antibody-drug conjugate (monoclonal antibody specific for TROP2 and a topoisomerase I (Topo-1) inhibitor) that has demonstrated promising efficacy in TNBC patients with a manageable safety profile.
Interventions
DRUG
Datopotamab deruxtecan
Dato-DXd is administered adjuvantly at 6 mg/kg IV for eight cycles.
DIAGNOSTIC_TEST
Circulating tumor DNA (ctDNA) testing
Circulating tumor DNA (ctDNA) testing is a type of biopsy that analyzes fragments of DNA shed by cancer cells into the bloodstream. These fragments, known as ctDNA, can provide valuable information about the genetic makeup of a tumor without needing a traditional tissue biopsy.
Primary outcome measures
The proportion of triple negative breast cancer (TNBC) with molecular residual disease (MRD)
Time frame: Up to 3 years after registration
The number of participants with triple negative breast cancer (TNBC) with molecular residual disease (MRD) only recurrence, which is defined as ctDNA positivity without radiographically measurable recurrence, during post-surgery surveillance.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
