( 2.2 ) • For adverse reactions, consider dosing interruption or dose reduction. ( 2.5 ) HRR Gene-Mutated mCRPC • The recommended dosage of TALZENNA is 0.5 mg taken orally once daily in combination with enzalutamide until disease progression or unacceptable toxicity. ( 2.3 ) • Patients should also receive a gonadotropic-releasing hormone (GnRH) analog concurrently or should have had bilateral orchiectomy.

The following clinically significant adverse reactions are described elsewhere in the labeling: • Myelodysplastic Syndrome/Acute Myeloid Leukemia [see Warnings and Precautions (5.1) ] • Myelosuppression [see Warnings and Precautions (5.2) ] Most common adverse reactions (≥20%) as a single agent, including laboratory abnormalities, are: • Hemoglobin decreased, neutrophils decreased, lymphocytes decreased, platelets decreased, fatigue, glucose increased, aspartate aminotransferase increased, alkaline phosphatase increased, alanine aminotransferase increased, calcium decreased, nausea, headache, vomiting, alopecia, diarrhea, and decreased appetite. ( 6.1 ) Most common adverse reactions (≥10%) in combination with enzalutamide, including laboratory abnormalities, are: • Hemoglobin decreased, neutrophils decreased, lymphocytes decreased, fatigue, platelets decreased, calcium decreased, nausea, decreased appetite, sodium decreased, phosphate decreased, fractures, magnesium decreased, dizziness, bilirubin increased, potassium decreased, and dysgeusia.

P-gp Inhibitors : Reduce the dose when coadministered with certain P-gp inhibitors. Monitor for increased adverse reactions. ( 2.7 , 7.1 ) • BCRP Inhibitors : Monitor for potential increased adverse reactions. ( 7.1 ) 7.1 Effect of Other Drugs on TALZENNA Effect of P-gp Inhibitors Breast Cancer Avoid coadministration of TALZENNA with the following P-gp inhibitors: itraconazole, amiodarone, carvedilol, clarithromycin, itraconazole, and verapamil. If coadministration of TALZENNA with these P-gp inhibitors cannot be avoided, reduce the dose of TALZENNA [see Dosage and Administration (2.7) ] . When the P-gp inhibitor is discontinued, increase the dose of TALZENNA [see Dosage and Administration (2.7) ] . Coadministration of TALZENNA with these P-gp inhibitors increased talazoparib concentrations [see Clinical Pharmacology (12.3) ] , which may increase the risk of adverse reactions. Monitor for increased adverse reactions and modify the dosage as recommended for adverse reactions when TALZENNA is coadministered with other P-gp inhibitors [see Dosage and Administration (2.5) ] . HRR Gene-mutated mCRPC The effect of coadministration of P-gp inhibitors on talazoparib exposure when TALZENNA is taken in combination with enzalutamide has not been studied. Monitor patients for increased adverse reactions and modify the dosage as recommended for adverse reactions when TALZENNA is coadministered with a P-gp inhibitor [see Dosage and Administration (2.5) ] . Effect of BCRP Inhibitors Monitor patients for increased adverse reactions and modify the dosage as recommended for adverse reactions when TALZENNA is coadministered with a BCRP inhibitor [see Dosage and Administration (2.5) ] . Coadministration of TALZENNA with BCRP inhibitors may increase talazoparib exposure [see Clinical Pharmacology (12.3) ] , which may increase the risk of adverse reactions.
