XTANDI can slow advanced prostate cancer progression while you focus more on what you love

XTANDI has been studied in men with advanced prostate cancer. Men in each study either had surgery to lower testosterone or were taking hormone therapy. In our studies, progression was defined as the cancer getting worse, as measured by scans, or if the patient died for any reason.


XTANDI is FDA approved to treat 3 forms of advanced prostate cancer.


Non-metastatic castration-resistant prostate cancer (nmCRPC)

In a study where the cancer had not spread to other parts of the body and no longer responded to treatment to lower testosterone, XTANDI lowered the chance of progression by 71%.

NEW

Metastatic castration-sensitive prostate cancer (mCSPC)

In a study where the cancer had spread to other parts of the body and still responded to treatment to lower testosterone, XTANDI lowered the chance of progression by 61%.

Metastatic castration-resistant prostate cancer (mCRPC)

In a study where the cancer had spread to other parts of the body and no longer responded to treatment to lower testosterone, XTANDI lowered the chance of progression by 83%.
