PHARMACOKINETICS SECTION.

12.3 Pharmacokinetics. After oral administration of mg TALZENNA once daily in patients, the recommended dose, the geometric mean [% coefficient of variation (CV%)] of AUC and maximum observed plasma concentration (Cmax) of talazoparib at steady-state was 208 (37%) ng.hr/mL and 16.4 (32%) ng/mL, respectively. The pharmacokinetics (PK) of talazoparib is linear from 0.025 mg to mg (2 times the recommended dose). The median accumulation ratio of talazoparib following repeated oral administration of mg once daily was in the range of 2.3 to 5.2. Talazoparib plasma concentrations reached steady-state within to weeks.. AbsorptionFollowing oral administration of talazoparib, the median time to Cmax (Tmax) was generally between to hours after dosing.. Food Effect Following single oral dose of 0.5 mg TALZENNA with high-fat, high-calorie food (approximately 800 to 1000 calories with 150, 250, and 500 to 600 calories from protein, carbohydrate, and fat, respectively), the mean Cmax of talazoparib was decreased by 46%, the median Tmax was delayed from to hours, and AUCinf was not affected.. DistributionThe mean apparent volume of distribution of talazoparib is 420 L. In vitro, protein binding of talazoparib is 74% and is independent of talazoparib concentration.. EliminationThe mean terminal plasma half-life (+-standard deviation) of talazoparib is 90 (+-58) hours, and the mean apparent oral clearance (inter-subject variability) is 6.45 L/h (31.1%) in cancer patients.. MetabolismTalazoparib undergoes minimal hepatic metabolism. The identified metabolic pathways of talazoparib in humans include mono-oxidation, dehydrogenation, cysteine conjugation of mono-desfluoro-talazoparib, and glucuronide conjugation.. ExcretionExcretion of talazoparib in urine was the major route of elimination. Approximately 68.7% (54.6% unchanged) of the total administered radioactive dose [14C]talazoparib was recovered in urine, and 19.7% (13.6% unchanged) was recovered in feces.. Specific PopulationsAge (18 to 88 years), sex, race (361 White, 41 Asian, 16 Black, Others, and 63 Not Reported), body weight (36 to 162 kg), and mild to severe hepatic impairment based on NCI criteria had no clinically relevant effect on the PK of talazoparib.. Pediatric PatientsThe PK of talazoparib have not been evaluated in patients <18 years of age.. Patients with Renal Impairment Talazoparib steady-state total exposure (AUC0-24) increased by 12%, 43%, and 163% in patients with mild (eGFR 60 89 mL/min/1.73 m2), moderate (eGFR 30 59 mL/min/1.73 m2), and severe (eGFR 15 29 mL/min/1.73 m2) renal impairment, respectively, relative to patients with normal renal function (eGFR >= 90 mL/min/1.73 m2). Talazoparib steady-state peak concentration (Cmax) increased by 11%, 32%, and 89% in patients with mild, moderate, and severe renal impairment, respectively, relative to patients with normal renal function. The PK of talazoparib has not been studied in patients requiring hemodialysis. There was no evidence of relationship between the protein binding of talazoparib and renal function.. Drug Interaction Studies Effect of Other Drugs on TalazoparibEffect of P-gp inhibitors: In patients with advanced solid tumors, coadministration of P-gp inhibitor (multiple 100 mg twice-daily doses of itraconazole) with single 0.5 mg talazoparib dose increased talazoparib AUCinf and Cmax by approximately 56% and 40%, respectively. Population PK analysis showed that coadministration with P-gp inhibitors including amiodarone, carvedilol, clarithromycin, itraconazole, and verapamil in clinical studies increased talazoparib exposure by 45% [see Dosage and Administration (2.5), Drug Interactions (7.1)]. Coadministration with P-gp inhibitors including azithromycin, atorvastatin, diltiazem, felodipine, fluvoxamine, and quercetin in clinical studies increased talazoparib exposure by 8% [see Dosage and Administration (2.5), Drug Interactions (7)].Effect of P-gp inducers: In patients with advanced solid tumors, coadministration of P-gp inducer (multiple 600 mg once-daily doses of rifampin) with single mg talazoparib dose increased talazoparib Cmax by 37% with no effect on talazoparib exposure.Effect of BCRP inhibitors: The effect of BCRP inhibitors on PK of talazoparib has not been studied. Coadministration with BCRP inhibitors may increase talazoparib exposure [see Drug Interactions (7)].Effect of acid-reducing agents on talazoparib: Coadministration of acid-reducing agents including proton pump inhibitors (PPI), histamine receptor antagonists (H2RA), or other acid reducing agents has no effect on the absorption of talazoparib.. In Vitro StudiesTalazoparib is substrate of P-gp and BCRP transporters. Talazoparib is not substrate of organic anion transporting polypeptide [OATP]1B1, OATP1B3, organic cationic transporter [OCT]1, OCT2, organic anion transporter [OAT]1, OAT3, bile salt export pump [BSEP], multidrug and toxin extrusion [MATE]1, and MATE2-K.Talazoparib is not an inhibitor of cytochrome (CYP)1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, or CYP3A4/5, or inducer of CYP1A2, CYP2B6, or CYP3A4.Talazoparib is not an inhibitor of transporters including P-gp, BCRP, OATP1B1, OATP1B3, OCT1, OCT2, OAT1, OAT3, BSEP, MATE1, and MATE2-K.Talazoparib is not an inhibitor of uridine-diphosphate glucuronosyltransferase (UGT) isoforms (1A1, 1A4, 1A6, 1A9, 2B7, and 2B15).

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY. 12.1Mechanism of Action. Talazoparib is an inhibitor of poly (ADP-ribose) polymerase (PARP) enzymes, including PARP1 and PARP2, which play role in DNA repair. In vitro studies with cancer cell lines that harbored defects in DNA repair genes, including BRCA and BRCA 2, have shown that talazoparib-induced cytotoxicity may involve inhibition of PARP enzymatic activity and increased formation of PARP-DNA complexes resulting in DNA damage, decreased cell proliferation, and apoptosis. Talazoparib anti-tumor activity was observed in human patient-derived xenograft breast cancer tumor models bearing mutated BRCA or mutated BRCA or wild-type BRCA and BRCA 2.. 12.2 Pharmacodynamics. Cardiac ElectrophysiologyThe effect of talazoparib on cardiac repolarization was evaluated in 37 patients with advanced solid tumors. Talazoparib had no large QTc prolongation (i.e., >20 ms) at the recommended dose.. 12.3 Pharmacokinetics. After oral administration of mg TALZENNA once daily in patients, the recommended dose, the geometric mean [% coefficient of variation (CV%)] of AUC and maximum observed plasma concentration (Cmax) of talazoparib at steady-state was 208 (37%) ng.hr/mL and 16.4 (32%) ng/mL, respectively. The pharmacokinetics (PK) of talazoparib is linear from 0.025 mg to mg (2 times the recommended dose). The median accumulation ratio of talazoparib following repeated oral administration of mg once daily was in the range of 2.3 to 5.2. Talazoparib plasma concentrations reached steady-state within to weeks.. AbsorptionFollowing oral administration of talazoparib, the median time to Cmax (Tmax) was generally between to hours after dosing.. Food Effect Following single oral dose of 0.5 mg TALZENNA with high-fat, high-calorie food (approximately 800 to 1000 calories with 150, 250, and 500 to 600 calories from protein, carbohydrate, and fat, respectively), the mean Cmax of talazoparib was decreased by 46%, the median Tmax was delayed from to hours, and AUCinf was not affected.. DistributionThe mean apparent volume of distribution of talazoparib is 420 L. In vitro, protein binding of talazoparib is 74% and is independent of talazoparib concentration.. EliminationThe mean terminal plasma half-life (+-standard deviation) of talazoparib is 90 (+-58) hours, and the mean apparent oral clearance (inter-subject variability) is 6.45 L/h (31.1%) in cancer patients.. MetabolismTalazoparib undergoes minimal hepatic metabolism. The identified metabolic pathways of talazoparib in humans include mono-oxidation, dehydrogenation, cysteine conjugation of mono-desfluoro-talazoparib, and glucuronide conjugation.. ExcretionExcretion of talazoparib in urine was the major route of elimination. Approximately 68.7% (54.6% unchanged) of the total administered radioactive dose [14C]talazoparib was recovered in urine, and 19.7% (13.6% unchanged) was recovered in feces.. Specific PopulationsAge (18 to 88 years), sex, race (361 White, 41 Asian, 16 Black, Others, and 63 Not Reported), body weight (36 to 162 kg), and mild to severe hepatic impairment based on NCI criteria had no clinically relevant effect on the PK of talazoparib.. Pediatric PatientsThe PK of talazoparib have not been evaluated in patients <18 years of age.. Patients with Renal Impairment Talazoparib steady-state total exposure (AUC0-24) increased by 12%, 43%, and 163% in patients with mild (eGFR 60 89 mL/min/1.73 m2), moderate (eGFR 30 59 mL/min/1.73 m2), and severe (eGFR 15 29 mL/min/1.73 m2) renal impairment, respectively, relative to patients with normal renal function (eGFR >= 90 mL/min/1.73 m2). Talazoparib steady-state peak concentration (Cmax) increased by 11%, 32%, and 89% in patients with mild, moderate, and severe renal impairment, respectively, relative to patients with normal renal function. The PK of talazoparib has not been studied in patients requiring hemodialysis. There was no evidence of relationship between the protein binding of talazoparib and renal function.. Drug Interaction Studies Effect of Other Drugs on TalazoparibEffect of P-gp inhibitors: In patients with advanced solid tumors, coadministration of P-gp inhibitor (multiple 100 mg twice-daily doses of itraconazole) with single 0.5 mg talazoparib dose increased talazoparib AUCinf and Cmax by approximately 56% and 40%, respectively. Population PK analysis showed that coadministration with P-gp inhibitors including amiodarone, carvedilol, clarithromycin, itraconazole, and verapamil in clinical studies increased talazoparib exposure by 45% [see Dosage and Administration (2.5), Drug Interactions (7.1)]. Coadministration with P-gp inhibitors including azithromycin, atorvastatin, diltiazem, felodipine, fluvoxamine, and quercetin in clinical studies increased talazoparib exposure by 8% [see Dosage and Administration (2.5), Drug Interactions (7)].Effect of P-gp inducers: In patients with advanced solid tumors, coadministration of P-gp inducer (multiple 600 mg once-daily doses of rifampin) with single mg talazoparib dose increased talazoparib Cmax by 37% with no effect on talazoparib exposure.Effect of BCRP inhibitors: The effect of BCRP inhibitors on PK of talazoparib has not been studied. Coadministration with BCRP inhibitors may increase talazoparib exposure [see Drug Interactions (7)].Effect of acid-reducing agents on talazoparib: Coadministration of acid-reducing agents including proton pump inhibitors (PPI), histamine receptor antagonists (H2RA), or other acid reducing agents has no effect on the absorption of talazoparib..

Talazoparib is not substrate of organic anion transporting polypeptide [OATP]1B1, OATP1B3, organic cationic transporter [OCT]1, OCT2, organic anion transporter [OAT]1, OAT3, bile salt export pump [BSEP], multidrug and toxin extrusion [MATE]1, and MATE2-K.Talazoparib is not an inhibitor of cytochrome (CYP)1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, or CYP3A4/5, or inducer of CYP1A2, CYP2B6, or CYP3A4.Talazoparib is not an inhibitor of transporters including P-gp, BCRP, OATP1B1, OATP1B3, OCT1, OCT2, OAT1, OAT3, BSEP, MATE1, and MATE2-K.Talazoparib is not an inhibitor of uridine-diphosphate glucuronosyltransferase (UGT) isoforms (1A1, 1A4, 1A6, 1A9, 2B7, and 2B15).

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES. EMBRACA Study (NCT01945775). Deleterious or Suspected Deleterious Germline BRCA-mutated (gBRCAm) HER2-negative Locally Advanced or Metastatic Breast CancerEMBRACA (NCT01945775) was an open-label study in which patients (N=431) with gBRCAm HER2-negative locally advanced or metastatic breast cancer were randomized 2:1 to receive TALZENNA mg or healthcare providers choice of chemotherapy (capecitabine, eribulin, gemcitabine, or vinorelbine) until disease progression or unacceptable toxicity. Randomization was stratified by prior lines of chemotherapy for metastatic disease (0 versus 1, 2, or 3), by triple-negative disease status (triple-negative breast cancer [TNBC] versus non-TNBC), and history of central nervous system (CNS) metastasis (yes versus no).Patients received no more than prior cytotoxic chemotherapy regimens for their metastatic or locally advanced disease. Patients were required to have received treatment with an anthracycline and/or taxane (unless contraindicated) in the neoadjuvant, adjuvant, and/or metastatic treatment setting. First-line treatment for advanced or metastatic disease with no prior adjuvant chemotherapy was allowed if the investigator determined that of the chemotherapy choices in the control arm would be an appropriate treatment option for the patient. Patients with prior platinum therapy for advanced disease were required to have no evidence of disease progression during platinum therapy. No prior treatment with PARP inhibitor was permitted. Of the 431 patients randomized in the EMBRACA study, 408 (95%) were centrally confirmed to have deleterious or suspected deleterious gBRCAm using clinical trial assay; out of which 354 (82%) were confirmed using the BRACAnalysis CDx(R). BRCA mutation status (breast cancer susceptibility gene [BRCA1] positive or breast cancer susceptibility gene [BRCA2] positive) was similar across both treatment arms.The median age of patients treated with TALZENNA was 46 years (range 28 to 84) and 51 years (range 24 to 89) among patients treated with chemotherapy. Among all randomized patients, 1% versus 2% were males, 67% versus 75% were White; 11% versus 11% were Asian, and 4% versus 1% were Black or African American in the TALZENNA and chemotherapy arms, respectively. Almost all patients (98%) in both arms had an Eastern Cooperative Oncology Group (ECOG) performance status of or 1. Approximately 56% of patients had estrogen receptor-positive and/or progesterone receptor-positive disease; 44% of patients had triple-negative disease, and the proportions were balanced across both treatment arms. Fifteen percent (15%) of patients in the TALZENNA arm and 14% of patients in the chemotherapy arm had history of CNS metastases. Ninety-one percent (91%) of patients in the TALZENNA arm had received prior taxane therapy, and 85% had received prior anthracycline therapy in any setting. Sixteen percent (16%) of patients in the TALZENNA arm and 21% of patients in the chemotherapy arm had received prior platinum treatment in any setting. The median number of prior cytotoxic regimens for patients with advanced breast cancer was one; 38% received no prior cytotoxic regimens for advanced or metastatic disease, 37% received one, 20% received two, and 5% received three or more prior cytotoxic regimens.The major efficacy outcome measure was progression-free survival (PFS) evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, as assessed by blinded independent central review (BICR). statistically significant improvement in PFS was demonstrated for TALZENNA compared with chemotherapy. sensitivity analysis of investigator-assessed PFS was consistent with the BICR-assessed PFS results. Consistent PFS results were observed across patient subgroups defined by study stratification factors (prior lines of chemotherapy, TNBC status, and history of CNS metastases).

If coadministration of TALZENNA with these P-gp inhibitors cannot be avoided, reduce the TALZENNA dose [see Dosage and Administration (2.5)]. When the P-gp inhibitor is discontinued, increase the TALZENNA dose (after 3-5 half-lives of the inhibitor) to the dose used prior to the initiation of the P-gp inhibitor [see Dosage and Administration (2.5), Clinical Pharmacology (12.3)].When coadministering TALZENNA with P-gp inhibitors not listed above, monitor patients for potential increased adverse reactions [see Dosage and Administration (2.5), Clinical Pharmacology (12.3)].. Effect of BCRP inhibitorsCoadministration with BCRP inhibitors may increase talazoparib exposure. If coadministration cannot be avoided, monitor patients for potential increased adverse reactions when coadministering [see Clinical Pharmacology (12.3)].

USE IN SPECIFIC POPULATIONS SECTION.

8 USE IN SPECIFIC POPULATIONS. Lactation: Advise women not to breastfeed. (8.2)Severe Renal Impairment: Reduce TALZENNA dose and monitor for potential increased adverse reactions as appropriate. (8.6, 12.3). Lactation: Advise women not to breastfeed. (8.2). Severe Renal Impairment: Reduce TALZENNA dose and monitor for potential increased adverse reactions as appropriate. (8.6, 12.3). 8.1 Pregnancy. Risk SummaryBased on findings from animal studies and its mechanism of action [see Clinical Pharmacology (12.1)], TALZENNA can cause embryo-fetal harm when administered to pregnant woman. There are no available data on TALZENNA use in pregnant women to inform drug-associated risk. In an animal reproduction study, the administration of talazoparib to pregnant rats during the period of organogenesis caused fetal malformations and structural skeletal variations and embryo-fetal death at maternal exposures that were 0.24 times the AUC in patients receiving the recommended dose of mg daily (see Data). Apprise pregnant women and females of reproductive potential of the potential risk to fetus.The background risk of major birth defects and miscarriage for the indicated population is unknown. In the general U.S. population, the estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies are 2% to 4% and 15% to 20%, respectively.. Data. Animal DataIn an embryo-fetal development toxicity study, pregnant rats received oral doses of 0.015, 0.05, and 0.15 mg/kg/day talazoparib during the period of organogenesis. Talazoparib caused embryo-fetal death at doses >=0.015 mg/kg/day (approximately 0.24 times the AUC in patients at the recommended dose). dose of 0.015 mg/kg/day caused decreased fetal body weights and an increased incidence of fetal malformations (depressed eye bulge, small eye, split sternebra, and fused cervical vertebral arch) and structural variations including misshapen or incomplete ossification of the sternebra, skull, rib, and vertebra.. 8.2 Lactation. Risk SummaryThere are no data on the presence of talazoparib in human milk, the effects of the drug on milk production, or the effects of the drug on the breastfed child. Because of the potential for serious adverse reactions in breastfed child from talazoparib, advise lactating women not to breastfeed during treatment with TALZENNA and for at least month after the final dose.. 8.3 Females and Males of Reproductive Potential. Pregnancy TestingA pregnancy test is recommended for females of reproductive potential prior to initiating TALZENNA treatment.. Contraception. FemalesTALZENNA can cause fetal harm when administered to pregnant women [see Use in Specific Populations (8.1)]. Advise females of reproductive potential to use effective contraception during treatment and for at least months following the last dose of TALZENNA.. MalesBased on genotoxicity and animal reproduction studies, advise male patients with female partners of reproductive potential and pregnant partners to use effective contraception during treatment with TALZENNA and for at least months following the last dose [see Use in Specific Populations (8.1), Nonclinical Toxicology (13.1)].. Infertility. MalesBased on animal studies, TALZENNA may impair fertility in males of reproductive potential [see Nonclinical Toxicology (13.1)]. 8.4 Pediatric Use. The safety and effectiveness of TALZENNA have not been established in pediatric patients.. 8.5 Geriatric Use. In clinical trials of TALZENNA enrolling 494 patients with advanced solid tumors who received TALZENNA mg daily as monotherapy, 85 (17%) patients were >=65 years of age, and this included 19 (4%) patients who were >=75 years old. There were patients >=85 years old. No overall differences in safety or effectiveness of TALZENNA were observed between these patients and younger patients, but greater sensitivity of some older individuals cannot be ruled out.. 8.6Renal Impairment. Patients with moderate or severe renal impairment have higher exposure to TALZENNA than patients with normal renal function. Reduce the recommended dose of TALZENNA in patients with moderate (CLcr 30 59 mL/min) and severe (CLcr 15 29 mL/min) renal impairment. Monitor patients with severe renal impairment for potential increased adverse reactions and adjust dosing accordingly [see Dosage and Administration (2.4), Clinical Pharmacology (12.3)]. No dose adjustment is required for patients with mild renal impairment (CLcr 60 89 mL/min). TALZENNA has not been studied in patients requiring hemodialysis [see Clinical Pharmacology (12.3)].. 8.7Hepatic Impairment. No dose modification is recommended for patients with mild, moderate, or severe hepatic impairment (based on NCI criteria) [see Clinical Pharmacology (12.3)].

WARNINGS AND PRECAUTIONS SECTION.

5 WARNINGS AND PRECAUTIONS. Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML): MDS/AML has been reported in <1% (3 out of 787, 0.4%) of solid tumor patients treated with TALZENNA in clinical studies. Monitor patients for hematological toxicity at baseline and monthly thereafter. Discontinue if MDS/AML is confirmed. (5.1)Myelosuppression: TALZENNA may affect hematopoiesis and can cause anemia, neutropenia, and/or thrombocytopenia. (5.2)Embryo-Fetal Toxicity: TALZENNA can cause fetal harm. Advise of the potential risk to the fetus and to use effective contraception. (5.3, 8.1, 8.3). Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML): MDS/AML has been reported in <1% (3 out of 787, 0.4%) of solid tumor patients treated with TALZENNA in clinical studies. Monitor patients for hematological toxicity at baseline and monthly thereafter. Discontinue if MDS/AML is confirmed. (5.1). Myelosuppression: TALZENNA may affect hematopoiesis and can cause anemia, neutropenia, and/or thrombocytopenia. (5.2). Embryo-Fetal Toxicity: TALZENNA can cause fetal harm. Advise of the potential risk to the fetus and to use effective contraception. (5.3, 8.1, 8.3). 5.1Myelodysplastic Syndrome/Acute Myeloid Leukemia. Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML) have been reported in patients who received TALZENNA. Overall, MDS/AML has been reported in <1% (3 out of 787, 0.4%) of solid tumor patients treated with TALZENNA in clinical studies. The duration of TALZENNA treatment in these three patients prior to developing MDS/AML was months, 24 months, and 60 months respectively. These patients had received previous chemotherapy with platinum agents and/or other DNA damaging agents including radiotherapy.Do not start TALZENNA until patients have adequately recovered from hematological toxicity caused by previous chemotherapy. Monitor complete blood counts for cytopenia at baseline and monthly thereafter. For prolonged hematological toxicities, interrupt TALZENNA and monitor blood counts weekly until recovery. If the levels have not recovered after weeks, refer the patient to hematologist for further investigations, including bone marrow analysis and blood sample for cytogenetics. If MDS/AML is confirmed, discontinue TALZENNA.. 5.2Myelosuppression Myelosuppression consisting of anemia, leukopenia/neutropenia, and/or thrombocytopenia, have been reported in patients treated with TALZENNA [see Adverse Reactions (6)]. Grade >=3 anemia, neutropenia, and thrombocytopenia were reported, respectively, in 39%, 21%, and 15% of patients receiving TALZENNA. Discontinuation due to anemia, neutropenia, and thrombocytopenia occurred, respectively, in 0.7%, 0.3%, and 0.3% of patients.Monitor complete blood count for cytopenia at baseline and monthly thereafter. Do not start TALZENNA until patients have adequately recovered from hematological toxicity caused by previous therapy. If this occurs, dose modifications (dosing interruption with or without dose reduction) are recommended [see Dosing Modifications (2.3)].. 5.3Embryo-Fetal Toxicity Based on its mechanism of action and findings from animal data, TALZENNA can cause fetal harm when administered to pregnant woman. In an animal reproduction study, administration of talazoparib to pregnant rats during the period of organogenesis caused fetal malformations and structural skeletal variations, and embryo-fetal death at exposures that were 0.24 times the area under the concentration-time curve (AUC) in patients receiving the recommended human dose of mg daily. Apprise pregnant women and females of reproductive potential of the potential risk to fetus. Advise females of reproductive potential to use effective contraception during treatment and for at least months following the last dose of TALZENNA [see Use in Specific Populations (8.1, 8.3), Clinical Pharmacology (12.1)].Based on findings from genetic toxicity and animal reproduction studies, advise male patients with female partners of reproductive potential or who are pregnant to use effective contraception during treatment and for at least months following the last dose of TALZENNA [see Use in Specific Populations (8.1, 8.3), Nonclinical Toxicology (13.1)].
