INDICATIONS

XTANDI is indicated for the treatment of patients with metastatic castration-resistant prostate cancer (CRPC).

DOSAGE AND ADMINISTRATION

Dosing Information

The recommended dose of XTANDI is 160 mg (four 40 mg capsules) administered orally once daily. XTANDI can be taken with or without food [see CLINICAL PHARMACOLOGY]. Swallow capsules whole. Do not chew, dissolve, or open the capsules.

Dose Modifications

If a patient experiences a ≥ Grade 3 toxicity or an intolerable side effect, withhold dosing for one week or until symptoms improve to ≤ Grade 2, then resume at the same or a reduced dose (120 mg or 80 mg), if warranted.

Concomitant Strong CYP2C8 Inhibitors

The concomitant use of strong CYP2C8 inhibitors should be avoided if possible. If patients must be coadministered a strong CYP2C8 inhibitor, reduce the XTANDI dose to 80 mg once daily. If coadministration of the strong inhibitor is discontinued, the XTANDI dose should be returned to the dose used prior to initiation of the strong CYP2C8 inhibitor [see DRUG INTERACTIONS and CLINICAL PHARMACOLOGY].
