7 DRUG INTERACTIONS
7.1 Effect of Other Drugs on Osimertinib
StrongCYP3AInducersCo-administeringTAGRISSOwithastrongCYP3A4inducerdecreasedtheexposure of osimertinib compared to administering TAGRISSO alone [see Clinical Pharmacology (12.3)].Decreasedosimertinibexposuremayleadtoreducedefficacy.Avoid co-administering TAGRISSO with strong CYP3A inducers. Increase theTAGRISSOdosagewhenco-administeringwithastrongCYP3A4inducerifconcurrentuseisunavoidable[see Dosage and Administration (2.4)].NodoseadjustmentsarerequiredwhenTAGRISSOisusedwithmoderateand/orweakCYP3Ainducers.7.2 Effect of Osimertinib on Other DrugsCo-administering TAGRISSO with a breast cancer resistant protein (BCRP) orP-glycoprotein(P-gp)substrateincreasedtheexposureofthesubstratecomparedtoadministeringitalone[see Clinical Pharmacology (12.3)].IncreasedBCRPorP-gpsubstrateexposuremayincreasetheriskofexposure-relatedtoxicity.Monitor for adverse reactions of the BCRP or P-gp substrate, unless otherwiseinstructedinitsapprovedlabeling,whenco-administeredwithTAGRISSO.
7.3 Drugs That Prolong the QTc IntervalTheeffectofco-administeringmedicinalproductsknowntoprolongtheQTcintervalwith TAGRISSO is unknown. When feasible, avoid concomitant administration ofdrugsknowntoprolongtheQTcintervalwithknownriskofTorsadesdepointes.Ifnotfeasibletoavoidconcomitantadministrationofsuchdrugs,conductperiodicECGmonitoring [see Warnings and Precautions (5.2) and Clinical Pharmacology (12.3)].
8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Risk SummaryBased on data from animal studies and its mechanism of action [see Clinical Pharmacology (12.1)], TAGRISSO can cause fetal harm when administered to apregnantwoman.TherearenoavailabledataonTAGRISSOuseinpregnantwomen.Administrationofosimertinibtopregnantratswasassociatedwithembryolethalityand reduced fetal growth at plasma exposures 1.5 times the exposure at therecommendedclinicaldose(see Data).Advisepregnantwomenofthepotentialriskto a fetus.IntheU.S.generalpopulation,theestimatedbackgroundriskofmajorbirthdefectsandmiscarriageinclinically-recognizedpregnanciesis2%to4%and15%to20%,respectively.
Data
AnimalDataWhenadministeredtopregnantratspriortoembryonicimplantationthroughtheendoforganogenesis(gestationdays2-20)atadoseof20mg/kg/day,whichproducedplasma exposures of approximately 1.5 times the clinical exposure, osimertinibcaused post-implantation loss and early embryonic death. When administered topregnant rats from implantation through theclosureof thehardpalate (gestationdays6to16)atdosesof1mg/kg/dayandabove(0.1timestheAUCobservedattherecommendedclinicaldoseof80mgoncedaily),anequivocal increaseintherate of fetal malformations and variations was observed in treated litters relativetothoseofconcurrentcontrols.Whenadministeredtopregnantdamsatdosesof30 mg/kg/day during organogenesis through lactation Day 6, osimertinib causedan increase in total litter loss and postnatal death. At a dose of 20 mg/kg/day,osimertinibadministrationduring thesameperiod resulted in increasedpostnataldeath aswell as a slight reduction inmeanpupweight at birth that increased inmagnitudebetweenlactationdays4and6.

12 CLINICAL PHARMACOLOGY
12.1 Mechanism of ActionOsimertinib is a kinase inhibitor of the epidermal growth factor receptor (EGFR),which binds irreversibly to certain mutant forms of EGFR (T790M, L858R, andexon 19 deletion) at approximately 9-fold lower concentrations than wild-type.Two pharmacologically-active metabolites (AZ7550 and AZ5104 circulating atapproximately10%oftheparent)withsimilarinhibitoryprofilestoosimertinibhavebeenidentifiedintheplasmaafteroraladministrationofosimertinib.AZ7550showedasimilarpotencytoosimertinib,whileAZ5104showedgreaterpotencyagainstexon19deletionandT790Mmutants(approximately8-fold)andwild-type(approximately15-fold)EGFR.In vitro,osimertinibalsoinhibitedtheactivityofHER2,HER3,HER4,ACK1,andBLKatclinicallyrelevantconcentrations.In cultured cells and animal tumor implantation models, osimertinib exhibited anti-tumoractivityagainstNSCLClinesharboringEGFR-mutations(T790M/L858R,L858R, T790M/exon 19 deletion, and exon 19 deletion) and, to a lesser extent, wild-typeEGFRamplifications.Osimertinibdistributedtothebraininmultipleanimalspecies(monkey,rat,andmouse)withbraintoplasmaAUCratiosofapproximately2 following oral dosing. These data are consistent with observations of tumorregressionandincreasedsurvivalinosimertinib-versuscontrol-treatedanimalsinapre-clinicalmutant-EGFRintracranialmousemetastasisxenograftmodel(PC9;exon19deletion).
12.2 PharmacodynamicsBasedonananalysisofdose-exposureresponserelationshipsoverthedoserangeof 20 mg (0.25 times the recommended dose) to 240 mg (3 times the recommended dose),noapparentrelationshipbetweenosimertinibexposureandoverallresponserate, duration of response and progression-free survival was identified; however,there were limited data available at the 20 mg dose. Over the same dose range,increased exposure led to increased probability of adverse reactions, specificallyrash,diarrheaandILD.
CardiacElectrophysiologyTheQTcintervalprolongationpotentialofosimertinibwasassessedin210patientswho received TAGRISSO 80 mg daily in AURA2. A central tendency analysis oftheQTcFdataatsteady-statedemonstratedthatthemaximummeanchangefrombaselinewas16.2msec (upperboundof two-sided90%confidence interval (CI)17.6 msec). A pharmacokinetic/pharmacodynamic analysis in AURA2 suggested aconcentration-dependentQTc intervalprolongationof14msec (upperboundoftwo-sided90%CI:16msec)atadoseofTAGRISSO80mg.
12.3 PharmacokineticsThe area under the plasma concentration-time curve (AUC) and maximal plasmaconcentration(Cmax)ofosimertinibincreaseddoseproportionallyover20to240mgdoserange(i.e.,0.25to3timestherecommendeddosage)afteroraladministrationandexhibitedlinearpharmacokinetics(PK).AdministrationofTAGRISSOorallyoncedaily resulted in approximately 3-fold accumulation with steady-state exposuresachieved after 15 days of dosing. At steady state, the Cmax to Cmin (minimalconcentration)ratiowas1.6-fold.
AbsorptionThemediantimetoCmaxofosimertinibwas6hours(range3-24hours).Followingadministrationofa20mgTAGRISSOtabletwithahigh-fat,high-caloriemeal (containingapproximately58gramsof fat and1000calories), theCmax and AUCofosimertinibwerecomparabletothatunderfastingconditions.
DistributionThemeanvolumeofdistributionatsteady-state (Vss/F)ofosimertinibwas918L.Plasmaproteinbindingofosimertinibwas95%.
EliminationOsimertinibplasmaconcentrationsdecreasedwithtimeandapopulationestimatedmeanhalf-lifeofosimertinibwas48hours,andoralclearance(CL/F)was14.3(L/h).
MetabolismThemainmetabolicpathwaysofosimertinibwereoxidation(predominantlyCYP3A)and dealkylation in vitro. Two pharmacologically active metabolites (AZ7550 andAZ5104) have been identified in the plasma after TAGRISSO oral administration.Thegeometricmeanexposure(AUC)ofeachmetabolite(AZ5104andAZ7550)wasapproximately10%oftheexposureofosimertinibatsteady-state.
ExcretionOsimertinib is primarily eliminated in the feces (68%) and to a lesser extent inthe urine (14%). Unchanged osimertinib accounted for approximately 2% of theelimination.
SpecificPopulationsNo clinically significant differences in the pharmacokinetics of osimertinib wereobservedbasedonage,sex,ethnicity,bodyweight,baselinealbumin,lineoftherapy,smokingstatus,renalfunction(creatinineclearance(CLcr)≥15mL/minbyCockcroft-Gault), or hepatic impairment (Child-Pugh A and B, or total bilirubin ≤ ULN and AST > ULN or total bilirubin between 1 to 3 times ULN and any AST). Thepharmacokinetics of osimertinib in patients with end-stage renal disease (CLcr<15mL/min)orseverehepaticimpairment(totalbilirubin3to10timesULNandanyAST)areunknown[see Use in Specific Populations (8.6) and (8.7)].
