More about this trial

Abemaciclib is a treatment for certain types of breast cancer that has spread. You have abemaciclib in combination with fulvestrant or an aromatase inhibitor Open a glossary item.

Before they become available as a treatment all drugs go through a clinical trial Open a glossary item. As part of the clinical trial researchers also look at how the drug might affect people’s quality of life. Open a glossary item  

But in a clinical trial there are several conditions on who can or cannot take part. And so this does not give a true picture of how treatment might affect the quality of life for people in the real world. 

In this study researchers ask women who are taking abemaciclib to fill in some questionnaires. The questions asked are about:

  • your general quality of life
  • symptoms and side effects
  • how you are managing your day to day roles and responsibilities

They also want to interview some women to find out more about this.

The aims of the study are to find out:

  • what is the experience of women taking abemaciclib outside of a clinical trial
  • how abemaciclib affects quality of life
  • how abemaciclib affects the roles and responsibilities of women taking it
