The data in the WARNINGS AND PRECAUTIONS section reflect exposure to TAGRISSO in 1813 patients with EGFR mutation-positive NSCLC who received TAGRISSO monotherapy at the recommended dose of 80 mg orally once daily until disease progression or unacceptable toxicity in four randomized, controlled trials [ADAURA (n=337), FLAURA (n=338), FLAURA2 (monotherapy arm; n=275), and AURA3 (n=279)] [see Clinical Studies (14) ] , two single arm trials [AURA Extension (n=201) {NCT01802632} and AURA2 (n=210)]{NCT02094261}, and one dose-finding study, AURA1 (n=173). Among 1813 patients who received TAGRISSO monotherapy, 82% were exposed for 6 months or longer and 67% were exposed for greater than one year. In this pooled safety population, the most common adverse reactions in ≥20% of 1813 patients who received TAGRISSO monotherapy were diarrhea (47%), rash (46%), musculoskeletal pain (38%), nail toxicity (34%), dry skin (32%), stomatitis (24%), and fatigue (21%). The most common laboratory abnormalities in ≥20% of 1813 patients who received TAGRISSO monotherapy were leukopenia (65%), lymphopenia (64%), thrombocytopenia (53%), anemia (52%), and neutropenia (36%). In addition to the 1813 patients, certain subsections in the WARNINGS AND PRECAUTIONS describe adverse reactions observed with exposure to TAGRISSO monotherapy (80 mg orally once daily until disease progression or unacceptable toxicity) following definitive platinum-based chemoradiation therapy (n=143) in the LAURA study. The data described below reflect exposure to TAGRISSO (80 mg daily) in 337 patients with EGFR mutation-positive resectable NSCLC, 143 patients with EGFR mutation-positive locally advanced, unresectable (stage III) NSCLC, and 833 patients with EGFR mutation-positive locally advanced or metastatic NSCLC in five randomized, controlled trials [ADAURA (n=337), LAURA (n=143), FLAURA (n=279), FLAURA2 (monotherapy arm; n=275), and AURA3 (n=279)]. The data also reflect exposure to TAGRISSO at the recommended dose of 80 mg daily given in combination with pemetrexed and platinum-based chemotherapy in 276 patients with EGFR mutation-positive locally advanced or metastatic NSCLC in one randomized controlled trial [FLAURA2 (n=276)]. Patients with a history of interstitial lung disease, drug induced interstitial disease or radiation pneumonitis that required steroid treatment, serious arrhythmia or baseline QTc interval greater than 470 msec on electrocardiogram were excluded from enrollment in these studies. Adjuvant Treatment of EGFR Mutation-Positive NSCLC - Monotherapy The safety of TAGRISSO was evaluated in ADAURA, a randomized, double-blind, placebo-controlled trial for the adjuvant treatment of patients with EGFR exon 19 deletions or exon 21 L858R mutation-positive NSCLC who had complete tumor resection, with or without prior adjuvant chemotherapy. At time of DFS analysis, the median duration of exposure to TAGRISSO was 22.5 months. Serious adverse reactions were reported in 16% of patients treated with TAGRISSO. The most common serious adverse reaction (≥1%) was pneumonia (1.5%). Adverse reactions leading to dose reductions occurred in 9% of patients treated with TAGRISSO. The most frequent adverse reactions leading to dose reductions or interruptions were diarrhea (4.5%), stomatitis (3.9%), nail toxicity (1.8%) and rash (1.8%). Adverse reactions leading to permanent discontinuation occurred in 11% of patients treated with TAGRISSO. The most frequent adverse reactions leading to discontinuation of TAGRISSO were interstitial lung disease (2.7%), and rash (1.2%).

Warnings & Cautions for Tagrisso

  • Interstitial Lung Disease (ILD)/Pneumonitis : Monitor for new or worsening pulmonary symptoms indicative of ILD/pneumonitis. For patients receiving TAGRISSO who have not received recent definite platinum-based chemoradiation therapy, permanently discontinue TAGRISSO in patients diagnosed with ILD/Pneumonitis. For patients who received recent definitive platinum-based chemoradiation therapy with Grade 1 ILD/pneumonitis continue TAGRISSO or interrupt and restart, as appropriate. Permanently discontinue TAGRISSO in patients diagnosed with Grade ≥2 ILD/pneumonitis. ( 2.5 , 5.1 )
  • QTc Interval Prolongation : Monitor electrocardiograms and electrolytes in patients who have a history or predisposition for QTc prolongation, or those who are taking medications that are known to prolong the QTc interval. Withhold, then restart at a reduced dose or permanently discontinue TAGRISSO based on severity. ( 2.5 , 5.2 )
  • Cardiomyopathy : Occurred in 3.8% of patients. Conduct cardiac monitoring, including left ventricular ejection fraction (LVEF) assessment in patients with cardiac risk factors. ( 2.5 , 5.3 )
  • Keratitis : Promptly refer patients with signs and symptoms of keratitis to an ophthalmologist for evaluation. ( 5.4 )
  • Erythema Multiforme Major, Stevens-Johnson Syndrome, and Toxic Epidermal Necrolysis : Withhold TAGRISSO if erythema multiforme major (EMM), Stevens-Johnson syndrome (SJS), or toxic epidermal necrolysis (TEN) is suspected and permanently discontinue if confirmed. ( 2.5 , 5.5 )
  • Cutaneous Vasculitis : Withhold TAGRISSO if cutaneous vasculitis is suspected, evaluate for systemic involvement, and consider dermatology consultation. If no other etiology can be identified, consider permanent discontinuation based on severity. ( 5.6 )
  • Aplastic Anemia : Withhold TAGRISSO if aplastic anemia is suspected and permanently discontinue TAGRISSO if confirmed. ( 2.5 , 5.7 )
  • Embryo-Fetal Toxicity : TAGRISSO can cause fetal harm. Advise females of potential risk to the fetus and to use effective contraception during treatment with TAGRISSO and for 6 weeks after last dose. Advise males to use effective contraception for 4 months after the last dose of TAGRISSO. ( 5.8 , 8.1 , 8.3 ) 5.1 Interstitial Lung Disease/Pneumonitis TAGRISSO can cause severe and fatal ILD/pneumonitis. Across clinical trials, interstitial lung disease (ILD)/pneumonitis occurred in 4% of the 1813 patients treated with TAGRISSO monotherapy who had not received recent definitive chemoradiation therapy; 0.4% of cases were fatal. ILD/Pneumonitis with TAGRISSO in Combination with Pemetrexed and Platinum-based Chemotherapy In the FLAURA2 study, ILD/pneumonitis occurred in 3.3% of the 276 patients who received TAGRISSO in combination with pemetrexed and platinum-based chemotherapy; 0.4% of cases were fatal. ILD/Pneumonitis Following Definitive Platinum-based Chemoradiation Therapy In the LAURA study, following definitive platinum-based chemoradiation therapy, ILD/pneumonitis, including radiation pneumonitis, occurred in 80 of the 143 patients (56%) who received TAGRISSO monotherapy and 28 of the 73 patients (38%) who received placebo. There was one fatal case (0.7%), 3.5% Grade 3, 34% Grade 2, and 18% Grade 1 adverse reactions of ILD/pneumonitis in TAGRISSO-treated patients. For TAGRISSO-treated patients, ILD/pneumonitis led to permanent discontinuation of TAGRISSO in 7% of patients and dosage interruptions of TAGRISSO in 35% of patients. Among the 46 patients who were rechallenged with TAGRISSO, 11% had recurrence of ILD/pneumonitis. In the 80 TAGRISSO-treated patients, ILD/pneumonitis resolved in 40%, resolved with sequelae in 1.3%, were resolving in 16%, did not resolve in 41%, and resulted in death in 1.3%. For patients receiving TAGRISSO who have not received recent definitive platinum-based chemoradiation therapy, withhold TAGRISSO and promptly investigate for ILD in patients who present with worsening or respiratory symptoms which may be indicative of ILD (e.g., dyspnea, cough, and fever). Permanently discontinue TAGRISSO if ILD/pneumonitis is confirmed [see Dosage and Administration (2.5) and Adverse Reactions (6.1) ]. For patients who have received recent definitive platinum-based chemoradiation therapy with Grade 1 ILD/pneumonitis continue TAGRISSO or interrupt and restart, as appropriate. Permanently discontinue TAGRISSO in patients diagnosed with Grade ≥2 ILD/pneumonitis [see Dosage and Administration (2.5) and Adverse Reactions (6.1) ]. 5.2 QTc Interval Prolongation TAGRISSO can cause heart rate-corrected QT (QTc) interval prolongation. Of the 1813 patients treated with TAGRISSO monotherapy in clinical trials, 1.1% were found to have a QTc >500 msec, and 4.3% of patients had an increase from baseline QTc >60 msec [see Clinical Pharmacology (12.2) ]. Of the 276 patients treated with TAGRISSO in combination with pemetrexed and platinum-based chemotherapy in the FLAURA2 study, 1.8% were found to have a QTc >500 msec, and 10.5% of patients had an increase from baseline QTc >60 msec. No QTc-related arrhythmias were reported. Clinical trials of TAGRISSO did not enroll patients with baseline QTc of >470 msec. Conduct periodic monitoring with ECGs and electrolytes in patients with congenital long QTc syndrome, congestive heart failure, electrolyte abnormalities, or those who are taking medications known to prolong the QTc interval. Permanently discontinue TAGRISSO in patients who develop QTc interval prolongation with signs/symptoms of life-threatening arrhythmia [see Dosage and Administration (2.5) ]. 5.3 Cardiomyopathy TAGRISSO can cause cardiomyopathy, including cardiac failure, chronic cardiac failure, congestive heart failure, pulmonary edema or decreased ejection fraction. Across clinical trials, cardiomyopathy occurred in 3.8% of the 1813 TAGRISSO-treated patients; 0.1% of cardiomyopathy cases were fatal. In the FLAURA2 study, cardiomyopathy occurred in 9% of the 276 patients who received TAGRISSO in combination with pemetrexed and platinum-based chemotherapy; 1.1% of cardiomyopathy cases were fatal. A decline in left ventricular ejection fraction (LVEF) ≥10 percentage points from baseline and to less than 50% LVEF occurred in 4.2% of 1557 patients who had baseline and at least one follow-up LVEF assessment. In the ADAURA study, 1.5% (5/325) of patients treated with TAGRISSO experienced LVEF decreases greater than or equal to 10 percentage points and a drop to less than 50%. In the LAURA study, following platinum-based chemoradiation therapy, 3% (4/135) of patients treated with TAGRISSO and no patients treated with placebo experienced LVEF decreases greater than or equal to 10 percentage points and a drop to less than 50%. In the FLAURA2 study, 8% (21/262) of patients treated with TAGRISSO in combination with pemetrexed and platinum-based chemotherapy, who had baseline and at least one follow-up LVEF assessment, experienced LVEF decreases greater than or equal to 10 percentage points and a drop to less than 50%. For patients who will be receiving TAGRISSO monotherapy, conduct cardiac monitoring, including assessment of LVEF at baseline and during treatment, in patients with cardiac risk factors. For patients who will be receiving TAGRISSO in combination with pemetrexed and platinum-based chemotherapy, conduct cardiac monitoring, including assessment of LVEF at baseline and during treatment, in all patients. Assess LVEF in patients who develop relevant cardiac signs or symptoms during treatment. For symptomatic congestive heart failure, permanently discontinue TAGRISSO [see Dosage and Administration (2.5) ]. 5.4 Keratitis Keratitis was reported in 0.6% of 1813 patients treated with TAGRISSO monotherapy in clinical trials. Promptly refer patients with signs and symptoms suggestive of keratitis (such as eye inflammation, lacrimation, light sensitivity, blurred vision, eye pain and/or red eye) to an ophthalmologist. 5.5 Erythema Multiforme Major, Stevens-Johnson Syndrome, and Toxic Epidermal Necrolysis Postmarketing cases consistent with erythema multiforme major (EMM), Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) have been reported in patients receiving TAGRISSO [see Postmarketing (6.2) ] . Withhold TAGRISSO if EMM, SJS, or TEN is suspected and permanently discontinue if confirmed. 5.6 Cutaneous Vasculitis Postmarketing cases of cutaneous vasculitis including leukocytoclastic vasculitis, urticarial vasculitis, and IgA vasculitis have been reported in patients receiving TAGRISSO [see Postmarketing (6.2) ] . Withhold TAGRISSO if cutaneous vasculitis is suspected, evaluate for systemic involvement, and consider dermatology consultation. If no other etiology can be identified, consider permanent discontinuation of TAGRISSO based on severity. 5.7 Aplastic Anemia Aplastic anemia has been reported in patients treated with TAGRISSO in clinical trials (0.06% of 1813) and postmarketing [see Postmarketing (6.2) ] . Some cases had a fatal outcome. Inform patients of the signs and symptoms of aplastic anemia including but not limited to, new or persistent fevers, bruising, bleeding, and pallor. If aplastic anemia is suspected, withhold TAGRISSO and obtain a hematology consultation. If aplastic anemia is confirmed, permanently discontinue TAGRISSO [see Dosage and Administration (2.5) ] . Perform complete blood count with differential before starting TAGRISSO, periodically throughout treatment, and more frequently if indicated. 5.8 Embryo-Fetal Toxicity Based on data from animal studies and its mechanism of action, TAGRISSO can cause fetal harm when administered to a pregnant woman. In animal reproduction studies, osimertinib caused post-implantation fetal loss when administered during early development at a dose exposure 1.5 times the exposure at the recommended clinical dose. When males were treated prior to mating with untreated females, there was an increase in preimplantation embryonic loss at plasma exposures of approximately 0.5 times those observed at the recommended dose of 80 mg once daily. Verify pregnancy status of females of reproductive potential prior to initiating TAGRISSO. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with TAGRISSO and for 6 weeks after the last dose. Advise males with female partners of reproductive potential to use effective contraception for 4 months after the last dose [see Use in Specific Populations (8.1 and 8.3) ].

Drug Interactions with Tagrisso

Effect of Other Drugs on Osimertinib Strong

CYP3A Inducers Co-administering TAGRISSO with a strong CYP3A4 inducer decreased the exposure of osimertinib compared to administering TAGRISSO alone . Decreased osimertinib exposure may lead to reduced efficacy. Avoid co-administering TAGRISSO with strong CYP3A inducers. Increase the TAGRISSO dosage when co-administering with a strong CYP3A4 inducer if concurrent use is unavoidable . No dose adjustments are required when TAGRISSO is used with moderate and/or weak CYP3A inducers.

Effect of Osimertinib on Other Drugs Co-administering

TAGRISSO with a breast cancer resistant protein (BCRP) or P-glycoprotein (P-gp) substrate increased the exposure of the substrate compared to administering it alone . Increased BCRP or P-gp substrate exposure may increase the risk of exposure-related toxicity. Monitor for adverse reactions of the BCRP or P-gp substrate, unless otherwise instructed in its approved labeling, when co-administered with TAGRISSO.

Drugs That Prolong the QTc Interval

The effect of co-administering medicinal products known to prolong the QTc interval with TAGRISSO is unknown. When feasible, avoid concomitant administration of drugs known to prolong the QTc interval with known risk of Torsades de pointes. If not feasible to avoid concomitant administration of such drugs, conduct periodic ECG monitoring.

Pregnancy Safety for Tagrisso

Pregnancy Risk Summary Based on data from animal studies and its mechanism of action , TAGRISSO can cause fetal harm when administered to a pregnant woman. There are no available data on TAGRISSO use in pregnant women. Administration of osimertinib to pregnant rats was associated with embryolethality and reduced fetal growth at plasma exposures 1.5 times the exposure at the recommended clinical dose (see Data ). Advise pregnant women of the potential risk to a fetus.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data When administered to pregnant rats prior to embryonic implantation through the end of organogenesis (gestation days 2-20) at a dose of 20 mg/kg/day, which produced plasma exposures of approximately 1.5 times the clinical exposure, osimertinib caused post-implantation loss and early embryonic death. When administered to pregnant rats from implantation through the closure of the hard palate (gestation days 6 to 16) at doses of 1 mg/kg/day and above (0.1 times the AUC observed at the recommended clinical dose of 80 mg once daily), an equivocal increase in the rate of fetal malformations and variations was observed in treated litters relative to those of concurrent controls.

When administered to pregnant dams at doses of 30 mg/kg/day during organogenesis through lactation Day 6, osimertinib caused an increase in total litter loss and postnatal death. At a dose of 20 mg/kg/day, osimertinib administration during the same period resulted in increased postnatal death as well as a slight reduction in mean pup weight at birth that increased in magnitude between lactation days 4 and 6.

Pediatric Use of Tagrisso

Pediatric Use The safety and effectiveness of TAGRISSO in pediatric patients have not been established.

Clinical Studies of Tagrisso

  • 14.1 Adjuvant Treatment of Early-Stage EGFR Mutation-Positive Non-Small Cell Lung Cancer (NSCLC) The efficacy of TAGRISSO was demonstrated in a randomized, double-blind, placebo-controlled trial (ADAURA [NCT02511106]) for the adjuvant treatment of patients with EGFR exon 19 deletions or exon 21 L858R mutation-positive NSCLC who had complete tumor resection, with or without prior adjuvant chemotherapy. Eligible patients with resectable tumors (stage IB – IIIA according to American Joint Commission on Cancer [AJCC] 7 th edition) were required to have predominantly non-squamous histology and EGFR exon 19 deletions or exon 21 L858R mutations identified prospectively from tumor tissue in a central laboratory by the cobas ® EGFR Mutation Test. Patients with clinically significant uncontrolled cardiac disease, prior history of ILD/pneumonitis, or who received treatment with any EGFR kinase inhibitor were not eligible for the study. Patients were randomized (1:1) to receive TAGRISSO 80 mg orally once daily or placebo following recovery from surgery and standard adjuvant chemotherapy if given. Patients who did not receive adjuvant chemotherapy were randomized within 10 weeks and patients who received adjuvant chemotherapy were randomized within 26 weeks following surgery. Randomization was stratified by mutation type (exon 19 deletions or exon 21 L858R mutations), race (Asian or other races) and pTNM staging (IB or II or IIIA) according to AJCC 7 th edition. Treatment was given for 3 years or until disease recurrence, or unacceptable toxicity. The major efficacy outcome measure was disease-free survival (DFS, defined as reduction in the risk of disease recurrence or death) in patients with stage II – IIIA NSCLC determined by investigator assessment. Additional efficacy outcome measures included DFS in the overall population (patients with stage IB – IIIA NSCLC), and overall survival (OS) in patients with stage II – IIIA NSCLC and in the overall population. A total of 682 patients were randomized to TAGRISSO (n=339) or placebo (n=343). The median age was 63 years (range 30-86 years); 70% were female; 64% were Asian and 72% were never smokers. Baseline World Health Organization (WHO) performance status was 0 (64%) or 1 (36%); 31% had stage IB, 35% II, and 34% IIIA. With regard to EGFR mutation status, 55% were exon 19 deletions and 45% were exon 21 L858R mutations. The majority (60%) of patients received adjuvant chemotherapy prior to randomization (27% IB; 70% II, 79% IIIA). ADAURA demonstrated a statistically significant difference in DFS for patients treated with TAGRISSO compared to patients treated with placebo. The final analysis of OS demonstrated a statistically significant improvement in OS for patients treated with TAGRISSO compared to patients treated with placebo. Median OS was not reached in either arm. In the overall population (IB-IIIA), the median follow-up time was 61.5 months in both treatment arms. Efficacy results from ADAURA are summarized in Table 14 and Figures 1 and 2, respectively. Table 14.

Figure_1 Figure_2 14.2 Locally Advanced, Unresectable (Stage III) EGFR Mutation Positive NSCLC The efficacy of TAGRISSO was evaluated in the LAURA trial [NCT03521154], a double blind, randomized, placebo-controlled study in adult patients with locally advanced, unresectable stage III NSCLC with EGFR exon 19 deletions or exon 21 L858R mutations whose disease had not progressed during or following definitive platinum-based chemoradiation therapy. Eligible patients were randomized within 42 days prior to study randomization and had a WHO performance status of 0 or 1. Prior to study enrollment, patients received concurrent chemoradiation therapy (cCRT) or sequential chemoradiation therapy (sCRT) regimens, where at least 2 cycles every 3 weeks or 5 doses of weekly platinum-based chemotherapy and definitive radiation were to be completed ≤6 weeks prior to randomization. The study excluded patients who had progressive disease during or following definitive chemoradiation therapy and patients with Grade ≥2 pneumonitis after chemoradiation therapy or any ILD prior to chemoradiation therapy. Patient tumor tissue samples were required to have an EGFR exon 19 deletion or exon 21 L858R mutation, as identified by the cobas® EGFR Mutation Test v2 in a central laboratory or by an FDA-approved test at a CLIA certified or accredited laboratory. Patients were randomized (2:1) to receive either TAGRISSO 80 mg orally once daily or placebo until disease progression or unacceptable toxicity. Randomization was stratified by prior chemoradiation strategy (cCRT vs sCRT), tumor staging prior to chemoradiation (IIIA vs IIIB/IIIC), and by region (China versus rest of the world). Post progression, all patients were offered open label TAGRISSO if, in the opinion of the treating healthcare provider, there was an expected clinical benefit. Tumor assessments were performed every 8 weeks until week 48, and then every 12 weeks. The major efficacy outcome measure was progression free survival (PFS) as assessed by blinded independent central review (BICR). Additional efficacy outcome measures included OS and CNS PFS. A total of 216 patients were randomized (2:1) to TAGRISSO (n=143) or placebo (n=73). The study population characteristics were: median age 63 years (range 36-84 years); 13% ≥75 years old; 61% female; 82% Asian, 14% White, 1.4% American Indian or Alaska Native and 2.3% had reported race as other; 6% were Hispanic or Latino; and 70% were never smokers. Baseline WHO performance status was 0 (51%) or 1 (49%); 35% of patients had stage IIIA, 49% of patients had stage IIIB and 16% of patients had stage IIIC NSCLC; 4% had squamous and 96% had non-squamous histology; 54% had exon 19 deletions and 45% had exon 21 L858R mutations. Prior to randomization, 89% of patients received cCRT and 11% of patients received sCRT. All patients received platinum-based chemotherapy (55% carboplatin-based chemotherapy and 44% cisplatin-based chemotherapy). The median total dose of radiation was 60 Gy for patients in both arms. LAURA demonstrated a statistically significant improvement in PFS for patients randomized to TAGRISSO as compared to placebo. Efficacy results from LAURA are summarized in Table 15, and the Kaplan-Meier curve for PFS is shown in Figure 3. While OS results were immature at the current analysis, with 36% of pre-specified deaths for the final analysis reported, no trend towards a detriment was observed. Table 15.

In an exploratory analysis of site(s) of relapse, the proportion of patients with new CNS lesions at the time of disease progression was 17/143 patients (12%) on the TAGRISSO arm and 26/73 patients (36%) on the placebo arm. Figure_3.jpg 14.3 Previously Untreated EGFR Mutation-Positive Metastatic NSCLC FLAURA – TAGRISSO Monotherapy The efficacy of TAGRISSO was demonstrated in a randomized, multicenter, double-blind, active-controlled trial (FLAURA [NCT02296125]) in patients with EGFR exon 19 deletions or exon 21 L858R mutation-positive, metastatic NSCLC, who had not received previous systemic treatment for metastatic disease. Patients were required to have measurable disease per RECIST v1.1, a WHO performance status of 0-1, and EGFR exon 19 deletions or exon 21 L858R mutation in tumor prospectively identified by the cobas ® EGFR Mutation Test in a central laboratory or by an investigational assay at a CLIA-certified or accredited laboratory. Patients with CNS metastases not requiring steroids and with stable neurologic status for at least two weeks after completion of definitive surgery or radiotherapy were eligible. Patients were assessed at the investigator’s discretion for CNS metastases if they had a history of, or suspected, CNS metastases at study entry. Patients were randomized (1:1) to receive TAGRISSO 80 mg orally once daily or to receive gefitinib 250 mg orally once daily or erlotinib 150 mg orally once daily until disease progression or unacceptable toxicity. Randomization was stratified by EGFR mutation type (exon 19 deletions or exon 21 L858R mutation) and ethnicity (Asian or non-Asian). Patients randomized to the control arm were offered TAGRISSO at the time of disease progression if tumor samples tested positive for the EGFR T790M mutation. The major efficacy outcome measure was progression-free survival (PFS), as assessed by investigator. Additional efficacy outcome measures included OS and overall response rate (ORR). A total of 556 patients were randomized to TAGRISSO (n=279) or to control (gefitinib n=183; erlotinib n=94). The median age was 64 years (range 26-93 years); 54% were <65 years of age; 63% were female; 62% were Asian and 64% were never smokers. Baseline WHO performance status was 0 (41%) or 1 (59%); 5% had Stage IIIb and 95% had Stage IV; and 7% received prior systemic cytotoxic chemotherapy as neoadjuvant or adjuvant therapy. With regard to EGFR tumor testing, 63% were exon 19 deletions and 37% were exon 21 L858R; 5 patients (<1%) also had a concomitant de novo T790M mutation. EGFR mutation status was confirmed centrally using the cobas ® EGFR Mutation Test in 90% of patients. At the time of the final data cut-off, of those randomized to TAGRISSO and to investigator’s choice erlotinib or gefitinib arm, 133 (48%) and 180 (65%) patients had received at least one subsequent treatment, respectively. Out of the 180 patients randomized to erlotinib or gefitinib who received subsequent treatment, 85 (47%) patients received TAGRISSO as first subsequent therapy. FLAURA demonstrated a statistically significant improvement in PFS for patients randomized to TAGRISSO as compared to erlotinib or gefitinib (see Table 16 and Figure 4). The final analysis of overall survival demonstrated a statistically significant improvement in overall survival in patients randomized to TAGRISSO compared to erlotinib or gefitinib (see Table 17 and Figure 5).

Kaplan-Meier Curves of PFS by Investigator Assessment in FLAURA In a supportive analysis of PFS according to blinded independent central review (BICR), median PFS was 17.7 months in the TAGRISSO arm compared to 9.7 months in the EGFR TKI comparator arm (HR=0.45; 95% CI: 0.36, 0.57). Figure 5. Kaplan-Meier Curves of Overall Survival in FLAURA Of 556 patients, 200 patients (36%) had baseline brain scans reviewed by BICR; this included 106 patients in the TAGRISSO arm and 94 patients in the investigator choice of EGFR TKI arm. Of these 200 patients, 41 had measurable CNS lesions per RECIST v1.1. Results of pre-specified exploratory analyses of CNS ORR and duration of response (DoR) by BICR in the subset of patients with measurable CNS lesions at baseline are summarized in Table 17. Table 17.

Patients were required to have measurable disease per RECIST v1.1, a WHO performance status of 0-1, and EGFR exon 19 deletions or exon 21 L858R mutations as identified by the cobas ® EGFR Mutation Test v2 performed prospectively in tissue samples in a central laboratory or by a local test performed in a CLIA-certified or accredited laboratory. Patients were randomized (1:1) to one of the following treatment arms:
  • TAGRISSO (80 mg) orally once daily with pemetrexed (500 mg/m 2 ) and investigator’s choice of cisplatin (75 mg/m2) or carboplatin (AUC5) administered intravenously on Day 1 of 21-day cycles for 4 cycles, followed by TAGRISSO (80 mg) orally once daily and pemetrexed (500 mg/m 2 ) administered intravenously every 3 weeks
  • TAGRISSO (80 mg) orally once daily Randomization was stratified by race (Chinese/Asian, Other races except-Chinese/Asian or other races), WHO performance status (0 or 1), and method for tissue testing (central or local). Patients received study therapy until intolerance to therapy, or the investigator determined that the patient was no longer experiencing clinical benefit. Progression-free survival, as assessed by investigator per RECIST 1.1 was the primary efficacy outcome measure. Overall survival was a key secondary outcome measure. Additional efficacy outcome measures included ORR and DoR. A total of 557 patients were randomized to either TAGRISSO in combination with pemetrexed and platinum-based chemotherapy (n=279) or TAGRISSO monotherapy (n=278). The median age was 61 years (range 26-85 years); 39% were ≥65 years and 8% were ≥75 years of age; 61% were female; 64% were Asian and 66% were never smokers. Baseline WHO PS was 0 (37%) or 1 (63%); 4% had locally advanced and 96% had metastatic NSCLC; and 1.8% received prior systemic cytotoxic chemotherapy as neoadjuvant or adjuvant therapy. With regard to EGFR tumor testing, 61% of tumors had exon 19 deletions and 38% had exon 21 L858R mutations; 0.7% of patients had tumors with both exon 19 deletions and exon 21 L858R. EGFR mutation status was centrally confirmed using the cobas ® EGFR Mutation Test v2 in 96% of patients. FLAURA2 demonstrated a statistically significant improvement in PFS for patients randomized to TAGRISSO in combination with pemetrexed and platinum-based chemotherapy as compared to TAGRISSO monotherapy (see Table 18 and Figure 6). While OS results were immature at the current analysis, with 45% of pre-specified deaths for the final analysis reported, no trend towards a detriment was observed. Table 18.

All patients were required to have EGFR T790M mutation-positive NSCLC identified by the cobas ® EGFR Mutation Test performed in a central laboratory prior to randomization. A total of 419 patients were randomized 2:1 to receive TAGRISSO (n=279) or platinum-based doublet chemotherapy (n=140). Randomization was stratified by ethnicity (Asian vs other races). Patients in the TAGRISSO arm received TAGRISSO 80 mg orally once daily until intolerance to therapy, disease progression, or investigator determination that the patient was no longer benefiting from treatment. Patients in the chemotherapy arm received pemetrexed 500 mg/m 2 with carboplatin AUC5 or pemetrexed 500 mg/m 2 with cisplatin 75 mg/m 2 on Day 1 of every 21-day cycle for up to 6 cycles. Patients whose disease had not progressed after four cycles of platinum-based chemotherapy could have received pemetrexed maintenance therapy (pemetrexed 500 mg/m 2 on Day 1 of every 21-day cycle). The major efficacy outcome measure was PFS according to Response Evaluation Criteria in Solid Tumors (RECIST v1.1) by investigator assessment. Additional efficacy outcome measures included ORR, DoR, and OS. Patients randomized to the chemotherapy arm who had radiological progression according to both investigator and BICR were permitted to cross over to receive treatment with TAGRISSO. The baseline demographic and disease characteristics of the overall trial population were: median age 62 years (range: 20-90 years), ≥75 years old (15%), female (64%), White (32%), Asian (65%), never smoker (68%), WHO performance status 0 or 1 (100%). Fifty-four percent (54%) of patients had extra-thoracic visceral metastases, including 34% with central nervous system (CNS) metastases (including 11% with measurable CNS metastases) and 23% with liver metastases. Forty-two percent (42%) of patients had metastatic bone disease. In AURA3, there was a statistically significant improvement in PFS in the patients randomized to TAGRISSO compared to chemotherapy (see Table 20 and Figure 7). No statistically significant difference was observed between the treatment arms at final OS analysis. At the time of the final OS analysis, 99 patients (71%) randomized to chemotherapy had crossed over to TAGRISSO treatment. Table 20.
