Clinical Trials for Breast Cancer

A Phase II Non-comparative Trial of Datopotamab Deruxtecan (Dato-DXd) or Trastuzumab Deruxtecan (T-DXd) in Patients With Metastatic HER2-negative (HER2-low or HER2-0) Breast Cancer After Progression on Prior Antibody Drug Conjugate Therapy

Investigational drug late phase

The trial is testing an investigational drug and is at least phase 2, suggesting that the drug has shown promise in phase 1 studies and might have a high chance of working well compared to other investigational drugs.

Active drug

Investigational drug(s) in this trial have shown anticancer activity in clinical trials

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

HealthScout AI summary: This trial enrolls adults with unresectable or metastatic HER2-negative (HER2-low or HER2-0) breast cancer who have progressed on prior ADC therapy, including those with stable or treated CNS metastases. Patients are randomized to receive either trastuzumab deruxtecan (an anti-HER2 ADC) or datopotamab deruxtecan (an investigational anti-TROP2 ADC), with crossover permitted at progression.
