DS-8201a in Human Epidermal Growth Factor Receptor 2 (HER2)-Positive Breast Cancer

Official Title

A Phase 2, Multicentre, Open-Label Study of DS-8201a, an Anti-HER2-Antibody Drug Conjugate (ADC) for HER2-Positive, Unresectable and/or Metastatic Breast Cancer Subjects Previously Treated With T-DM1

Summary:

Some HER-2 breast cancer patients do not respond or build resistance to current treatment. DS-8201a is a new experimental product that is a combination of an antibody and a drug. It has not yet been approved for use. DS-8201a may slow down tumour growth. This might improve outcomes for these patients.
