A Study to Assess the Effectiveness of Trastuzumab Deruxtecan in Chinese Breast Cancer Patients (REFRESH)

This multi-center observational prospective study will collect real-world clinical and patient-reported outcome data from eligible patients with unresectable or metastatic HER2+ breast cancer who have received one or more prior anti-HER2-based regimens or patients with unresectable or metastatic HER2-low (IHC 1+ or IHC 2+, ISH-) breast cancer who have received at least a prior systemic therapy in the metastatic setting, or developed disease recurrence during or within 6 months of completing adjuvant chemotherapy.

Trial Summary

The primary objective of the study is to evaluate real-world time to next treatment or date of death from index date (T-DXd treatment initiation date)(rwTTNT) in each cohort. The secondary objectives of this study are to describe treatment patterns in eligible patients with HER2+ or HER2-low unresectable or mBC who are newly initiating T-DXd in a real-world setting, to describe demographic and clinical characteristics, to assess the safety and tolerability through the collection of physician-reported SEIs, to characterize the management of SEIs, to evaluate real-world time to treatment discontinuation (rwTTD) of T-DXd, and to evaluate patient-reported tolerability. This decision to treat the patient with T-DXd will be made prior to, and independent of, their participation in this study. Eligible patients willing to participate will be enrolled consecutively in the study and followed up from index date (T-DXd treatment initiation date) until end of study, death, or withdrawal of consent, or loss to follow-up (LTFU), or study closure, whichever occurs first.
