1. What is Xtandi and what is it used for

Xtandi contains the active substance enzalutamide. Xtandi is used for the treatment of adult men
with prostate cancer:

• Who no longer respond to hormone therapy or surgical treatment to reduce testosterone Or
• Who have spread to other parts of the body and respond to hormone therapy or surgical treatment to reduce testosterone. Or
• For those who have previously undergone prostate removal or radiotherapy and have a rapidly increasing PSA, but the cancer has not spread to other parts of the body and responds to hormone therapy to reduce testosterone.

How Xtandi works
Xtandi is a medicine that works by blocking the activity of hormones called androgens (such as
testosterone). By blocking androgens, enzalutamide stops the growth and division of prostate cancer cells.

2. What you need to know before taking Xtandi
