Research summary
Breast cancer remains the most common cancer and the second leading cause of cancer mortality in women globally. In 2015, there were 2.4 million new cancer cases leading to 523,000 deaths worldwide. Approximately 20% of breast cancer cases test positive for a protein called human epidermal growth factor receptor 2 (HER2), which promotes the growth of cancer cells. HER2-positive breast cancers tend to be more aggressive and have worse outcomes than other types of breast cancer. This study involves research of a potential new drug, DS-8201a, that is being developed for cancer treatment. It will compare the activity of DS-8201a in participants with HER2-positive, versus 2 investigator’s choice options that are currently part of guideline recommendations for this line of therapy.
The following drugs have been selected as the comparator treatments in this study:
• Trastuzumab/capecitabine or
• Lapatinib/capecitabine
The comparator drugs are approved in the United Kingdom for HER2 positive breast cancer.
Depending on which treatment group participants are in, they will take DS-8201a or the other treatment (trastuzumab/capecitabine or lapatinib/capecitabine).
The study comprises of a screening part (up to 28 days), a Treatment period and a Follow-up period.
It is expected that about 600 patients will participate in approximately 160 sites around the world. In the UK it is expected that the study will take place in 11 sites.REC name
