Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

The purpose of this study is to test the safety and effectiveness of the sequence of two investigational drugs (trastuzumab deruxtecan followed by datopotamab deruxtecan, or datopotamab deruxtecan followed by trastuzumab deruxtecan) to learn whether the treatment works in treating HER2-negative (HER2-low or HER2-0) metastatic breast cancer. The names of the study drugs involved in this study are: * Datopotamab deruxtecan (a type of antibody drug conjugate) * Trastuzumab deruxtecan (a type of antibody drug conjugate)

Official Title

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
