metastatic castration-resistant prostate cancer (CRPC). (1)
metastatic high-risk castration-sensitive prostate cancer (CSPC). (1)
DOSAGE AND ADMINISTRATION
Metastatic castration-resistant prostate cancer:
ZYTIGA 1,000 mg orally once daily with prednisone 5 mg orally twice daily. (2.1)
Metastatic castration-sensitive prostate cancer:
ZYTIGA 1,000 mg orally once daily with prednisone 5 mg orally once daily. (2.2)
Patients receiving ZYTIGA should also receive a gonadotropin-releasing hormone (GnRH) analog concurrently or should have had bilateral orchiectomy. ZYTIGA must be taken on an empty stomach with water at least 1 hour before or 2 hours after a meal. Do not crush or chew tablets. (2.3)
Dose Modification:
For patients with baseline moderate hepatic impairment (Child-Pugh Class B), reduce the ZYTIGA starting dose to 250 mg once daily. (2.4)
For patients who develop hepatotoxicity during treatment, hold ZYTIGA until recovery. Retreatment may be initiated at a reduced dose. ZYTIGA should be discontinued if patients develop severe hepatotoxicity. (2.4)

WARNINGS AND PRECAUTIONS
Mineralocorticoid excess: Closely monitor patients with cardiovascular disease. Control hypertension and correct hypokalemia before treatment. Monitor blood pressure, serum potassium and symptoms of fluid retention at least monthly. (5.1)
Adrenocortical insufficiency: Monitor for symptoms and signs of adrenocortical insufficiency. Increased dosage of corticosteroids may be indicated before, during and after stressful situations. (5.2)
Hepatotoxicity: Can be severe and fatal. Monitor liver function and modify, interrupt, or discontinue ZYTIGA dosing as recommended. (5.3)
Increased fractures and mortality in combination with radium Ra 223 dichloride: Use of ZYTIGA plus prednisone/prednisolone in combination with radium Ra 223 dichloride is not recommended. (5.4)
Embryo-Fetal Toxicity: ZYTIGA can cause fetal harm. Advise males with female partners of reproductive potential to use effective contraception. (5.5, 8.1, 8.3)
ADVERSE REACTIONS

To report SUSPECTED ADVERSE REACTIONS, contact Janssen Biotech, Inc. at 1-800-526-7736 (1-800-JANSSEN) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
DRUG INTERACTIONS
CYP3A4 Inducers: Avoid concomitant strong CYP3A4 inducers during ZYTIGA treatment. If a strong CYP3A4 inducer must be co-administered, increase the ZYTIGA dosing frequency. (2.5, 7.1)
CYP2D6 Substrates: Avoid co-administration of ZYTIGA with CYP2D6 substrates that have a narrow therapeutic index. If an alternative treatment cannot be used, exercise caution and consider a dose reduction of the concomitant CYP2D6 substrate. (7.2)
USE IN SPECIFIC POPULATIONS
Do not use ZYTIGA in patients with baseline severe hepatic impairment (Child-Pugh Class C). (8.6)
