How XTANDI is thought to work

XTANDI is an androgen receptor inhibitor. Androgens are a group of hormones that includes testosterone. Androgen receptor inhibitors interfere with the connection between androgens and androgen receptors. This can help slow cancer cell growth.

When androgen connects with an androgen receptor, it may cause tumor cells to grow.

How XTANDI works

XTANDI helps to decrease how often androgen can connect with an androgen receptor. This can keep tumors from growing.

This is how XTANDI was shown to work in laboratory studies. Clinical significance is unknown.

As a result, the prostate tumor may stop growing and the cancer cells may die.
