“I was keen to go on a clinical trial. I wanted to try new cancer treatments and hopefully help future generations.”
A study looking at olaparib, AZD6738 and AZD1775 for triple negative breast cancer (VIOLETTE)
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This study is comparing olaparib on its own and in combination with AZD6738 for triple negative breast cancer that has spread.
To take part in the study, the team want to know if your cancer has changes (
This study was also looking at AZD1775 in combination with olaparib. But this combination is no longer been used.
