About this study

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 outcomes

The proportion of triple negative breast cancer (TNBC) with molecular residual disease (MRD) (Up to 3 years after registration)
