2 DOSAGE AND ADMINISTRATION

2.1 Selection of Patients with Metastatic NSCLC

Select patients for the treatment of metastatic NSCLC with Tarceva based on the presence of EGFR exon 19 deletions or exon 21 (L858R) substitution mutations in tumor or plasma specimens . If these mutations are not detected in a plasma specimen, test tumor tissue if available. Information on FDA-approved tests for the detection of EGFR mutations in NSCLC is available at: http://www.fda.gov/CompanionDiagnostics.

2.2 Recommended Dose – NSCLC

The recommended daily dose of Tarceva for NSCLC is 150 mg taken on an empty stomach, i.e., at least one hour before or two hours after the ingestion of food. Treatment should continue until disease progression or unacceptable toxicity occurs.

2.3 Recommended Dose – Pancreatic Cancer

The recommended daily dose of Tarceva for pancreatic cancer is 100 mg taken once daily in combination with gemcitabine. Take Tarceva on an empty stomach, i.e., at least one hour before or two hours after the ingestion of food. Treatment should continue until disease progression or unacceptable toxicity occurs .

5 WARNINGS AND PRECAUTIONS

5.1 Interstitial Lung Disease (ILD)

Cases of serious ILD, including fatal cases, can occur with Tarceva treatment. The overall incidence of ILD in approximately 32,000 TARCEVA-treated patients in uncontrolled studies and studies with concurrent chemotherapy was approximately 1.1%. In patients with ILD, the onset of symptoms was between 5 days to more than 9 months (median 39 days) after initiating Tarceva therapy.

Withhold Tarceva for acute onset of new or progressive unexplained pulmonary symptoms such as dyspnea, cough, and fever pending diagnostic evaluation. If ILD is confirmed, permanently discontinue Tarceva .

5.2 Renal Failure

Hepatorenal syndrome, severe acute renal failure including fatal cases, and renal insufficiency can occur with Tarceva treatment. Renal failure may arise from exacerbation of underlying baseline hepatic impairment or severe dehydration. The pooled incidence of severe renal impairment in the 3 monotherapy lung cancer studies was 0.5% in the Tarceva arms and 0.8% in the control arms. The incidence of renal impairment in the pancreatic cancer study was 1.4% in the Tarceva plus gemcitabine arm and 0.4% in the control arm. Withhold Tarceva in patients developing severe renal impairment until renal toxicity is resolved. Perform periodic monitoring of renal function and serum electrolytes during Tarceva treatment .

5.3 Hepatotoxicity with or without Hepatic Impairment

Hepatic failure and hepatorenal syndrome, including fatal cases, can occur with Tarceva treatment in patients with normal hepatic function; the risk of hepatic toxicity is increased in patients with baseline hepatic impairment. In clinical studies where patients with moderate to severe hepatic impairment were excluded, the pooled incidence of hepatic failure in the 3 monotherapy lung cancer studies was 0.4% in the Tarceva arms and 0% in the control arms. The incidence of hepatic failure in the pancreatic cancer study was 0.4% in the Tarceva plus gemcitabine arm and 0.4% in the control arm. In a pharmacokinetic study in 15 patients with moderate hepatic impairment (Child-Pugh B) associated with significant liver tumor burden, 10 of these 15 patients died within 30 days of the last Tarceva dose. One patient died from hepatorenal syndrome, 1 patient died from rapidly progressing liver failure and the remaining 8 patients died from progressive disease. Six out of the 10 patients who died had baseline total bilirubin > 3 x ULN.

Perform periodic liver testing (transaminases, bilirubin, and alkaline phosphatase) during treatment with Tarceva. Increased frequency of monitoring of liver function is required for patients with pre-existing hepatic impairment or biliary obstruction. Withhold Tarceva in patients without pre-existing hepatic impairment for total bilirubin levels greater than 3 times the upper limit of normal or transaminases greater than 5 times the upper limit of normal. Withhold Tarceva in patients with pre-existing hepatic impairment or biliary obstruction for doubling of bilirubin or tripling of transaminases values over baseline. Discontinue Tarceva in patients whose abnormal liver tests meeting the above criteria do not improve significantly or resolve within three weeks .

5.4 Gastrointestinal Perforation

Gastrointestinal perforation, including fatal cases, can occur with Tarceva treatment. Patients receiving concomitant anti-angiogenic agents, corticosteroids, NSAIDs, or taxane-based chemotherapy, or who have prior history of peptic ulceration or diverticular disease may be at increased risk of perforation . The pooled incidence of gastrointestinal perforation in the 3 monotherapy lung cancer studies was 0.2% in the Tarceva arms and 0.1% in the control arms. The incidence of gastrointestinal perforation in the pancreatic cancer study was 0.4% in the Tarceva plus gemcitabine arm and 0% in the control arm. Permanently discontinue Tarceva in patients who develop gastrointestinal perforation .

5.5 Bullous and Exfoliative Skin Disorders

Bullous, blistering and exfoliative skin conditions, including cases suggestive of Stevens-Johnson syndrome/toxic epidermal necrolysis, which in some cases were fatal, can occur with Tarceva treatment . The pooled incidence of bullous and exfoliative skin disorders in the 3 monotherapy lung cancer studies was 1.2% in the Tarceva arms and 0% in the control arms. The incidence of bullous and exfoliative skin disorders in the pancreatic cancer study was 0.4% in the Tarceva plus gemcitabine arm and 0% in the control arm. Discontinue Tarceva treatment if the patient develops severe bullous, blistering or exfoliating conditions .

5.6 Cerebrovascular Accident

In the pancreatic carcinoma trial, seven patients in the TARCEVA/gemcitabine group developed cerebrovascular accidents. One of these was hemorrhagic and was the only fatal event. In comparison, in the placebo/gemcitabine group there were no cerebrovascular accidents. The pooled incidence of cerebrovascular accident in the 3 monotherapy lung cancer studies was 0.6% in the Tarceva arms and not higher than that observed in the control arms.

5.7 Microangiopathic Hemolytic Anemia with Thrombocytopenia

The pooled incidence of microangiopathic hemolytic anemia with thrombocytopenia in the 3 monotherapy lung cancer studies was 0% in the Tarceva arms and 0.1% in the control arms. The incidence of microangiopathic hemolytic anemia with thrombocytopenia in the pancreatic cancer study was 1.4% in the Tarceva plus gemcitabine arm and 0% in the control arm.

5.8 Ocular Disorders

Decreased tear production, abnormal eyelash growth, keratoconjunctivitis sicca or keratitis can occur with Tarceva treatment and can lead to corneal perforation or ulceration . The pooled incidence of ocular disorders in the 3 monotherapy lung cancer studies was 17.8% in the Tarceva arms and 4% in the control arms. The incidence of ocular disorders in the pancreatic cancer study was 12.8% in the Tarceva plus gemcitabine arm and 11.4% in the control arm. Interrupt or discontinue Tarceva therapy if patients present with acute or worsening ocular disorders such as eye pain .

5.9 Hemorrhage in Patients Taking Warfarin

Severe and fatal hemorrhage associated with International Normalized Ratio (INR) elevations can occur when Tarceva and warfarin are administered concurrently. Regularly monitor prothrombin time and INR during Tarceva treatment in patients taking warfarin or other coumarin-derivative anticoagulants .

5.10 Embryo-fetal Toxicity

Based on animal data and its mechanism of action, Tarceva can cause fetal harm when administered to a pregnant woman. When given during organogenesis, Tarceva administration resulted in embryo-fetal lethality and abortion in rabbits at exposures approximately 3 times the exposure at the recommended human daily dose of 150 mg. Advise pregnant women of the potential risk to a fetus.

Advise females of reproductive potential to use effective contraception during therapy and for one month after the last dose of Tarceva [see Use in Specific Populations (8.1) and ( 8.3 ), Clinical Pharmacology (12.1)].

6.1 Clinical Trial Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Safety evaluation of Tarceva is based on more than 1200 cancer patients who received Tarceva as monotherapy, more than 300 patients who received Tarceva 100 or 150 mg plus gemcitabine, and 1228 patients who received Tarceva concurrently with other chemotherapies. The most common adverse reactions with Tarceva are rash and diarrhea usually with onset during the first month of treatment. The incidences of rash and diarrhea from clinical studies of Tarceva for the treatment of NSCLC and pancreatic cancer were 70% for rash and 42% for diarrhea.

Non-Small Cell Lung Cancer

First-Line Treatment of Patients with EGFR Mutations

The most frequent (≥ 30%) adverse reactions in TARCEVA-treated patients were diarrhea, asthenia, rash, cough, dyspnea, and decreased appetite. In TARCEVA-treated patients the median time to onset of rash was 15 days and the median time to onset of diarrhea was 32 days.

The most frequent Grade 3-4 adverse reactions in TARCEVA-treated patients were rash and diarrhea.

Dose interruptions or reductions due to adverse reactions occurred in 37% of TARCEVA-treated patients, and 14.3% of TARCEVA-treated patients discontinued therapy due to adverse reactions. In TARCEVA-treated patients, the most frequently reported adverse reactions leading to dose modification were rash (13%), diarrhea (10%), and asthenia (3.6%).

Common adverse reactions in Study 1, occurring in at least 10% of patients who received Tarceva or chemotherapy and an increase in ≥ 5% in the TARCEVA-treated group, are graded by National Cancer Institute Common Toxicity Criteria for Adverse Events version 3.0 (NCI-CTCAE v3.0) Grade in Table 1. The median duration of Tarceva treatment was 9.6 months in Study 1.

Liver function test abnormalities [including elevated alanine aminotransferase (ALT), aspartate aminotransferase (AST) and bilirubin] were observed in patients receiving single-agent Tarceva 150 mg. These elevations were mainly transient or associated with liver metastases. Grade 2 [> 2.5 – 5.0 x upper limit of normal (ULN)] ALT elevations occurred in 4% and < 1% of Tarceva and placebo treated patients, respectively. Grade 3 (> 5.0 – 20.0 x ULN) elevations were not observed in TARCEVA-treated patients. Tarceva dosing should be interrupted or discontinued if changes in liver function are severe .

Pancreatic Cancer - Tarceva Administered Concurrently with Gemcitabine

This was a randomized, double-blind, placebo-controlled study of Tarceva (150 mg or 100 mg daily) or placebo plus gemcitabine (1000 mg/m2 by intravenous infusion) in patients with locally advanced, unresectable or metastatic pancreatic cancer (Study 5). The safety population comprised 282 patients in the Tarceva group (259 in the 100 mg cohort and 23 in the 150 mg cohort) and 280 patients in the placebo group (256 in the 100 mg cohort and 24 in the 150 mg cohort).

Adverse reactions that occurred in at least 10% of patients treated with Tarceva 100 mg plus gemcitabine in the randomized trial of patients with pancreatic cancer (Study 5) were graded according to NCI-CTC v2.0 in Table 4.

The most common adverse reactions in pancreatic cancer patients receiving Tarceva 100 mg plus gemcitabine were fatigue, rash, nausea, anorexia and diarrhea. In the Tarceva plus gemcitabine arm, Grade 3-4 rash and diarrhea were each reported in 5% of patients. The median time to onset of rash and diarrhea was 10 days and 15 days, respectively. Rash and diarrhea each resulted in dose reductions in 2% of patients, and resulted in study discontinuation in up to 1% of patients receiving Tarceva plus gemcitabine. Severe adverse reactions (≥ Grade 3 NCI-CTC) in the Tarceva plus gemcitabine group with incidences < 5% included syncope, arrhythmias, ileus, pancreatitis, hemolytic anemia including microangiopathic hemolytic anemia with thrombocytopenia, myocardial infarction/ischemia, cerebrovascular accidents including cerebral hemorrhage, and renal insufficiency .

The 150 mg cohort was associated with a higher rate of certain class-specific adverse reactions including rash and required more frequent dose reduction or interruption.

Indications: Selected Low Frequency Adverse Reactions

Gastrointestinal Disorders

Cases of gastrointestinal bleeding (including fatalities) have been reported, some associated with concomitant warfarin or NSAID administration . These adverse reactions were reported as peptic ulcer bleeding (gastritis, gastroduodenal ulcers), hematemesis, hematochezia, melena and hemorrhage from possible colitis.

6.2 Post-Marketing Experience

The following adverse reactions have been identified during post approval use of Tarceva. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Musculoskeletal and Connective Tissue Disorders: myopathy, including rhabdomyolysis, in combination with statin therapy

Eye Disorders: ocular inflammation including uveitis

7 DRUG INTERACTIONS

CYP3A4 Inhibitors

Co-administration of Tarceva with a strong CYP3A4 inhibitor or a combined CYP3A4 and CYP1A2 inhibitor increased Tarceva exposure. Tarceva is metabolized primarily by CYP3A4 and to a lesser extent by CYP1A2. Increased Tarceva exposure may increase the risk of exposure-related toxicity .

Avoid co-administering Tarceva with strong CYP3A4 inhibitors (e.g., boceprevir, clarithromycin, conivaptan, indinavir, itraconazole, ketoconazole, lopinavir/ritonavir, nefazodone, nelfinavir, posaconazole, ritonavir, saquinavir, telithromycin, voriconazole, grapefruit or grapefruit juice) or a combined CYP3A4 and CYP1A2 inhibitor (e.g., ciprofloxacin). Reduce the Tarceva dosage when co-administering with a strong CYP3A4 inhibitor or a combined CYP3A4 and CYP1A2 inhibitor if co-administration is unavoidable .

CYP3A4 Inducers

Pre-treatment with a CYP3A4 inducer prior to Tarceva decreased Tarceva exposure . Increase the Tarceva dosage if co-administration with CYP3A4 inducers (e.g., carbamazepine, phenytoin, rifampin, rifabutin, rifapentine, phenobarbital and St. John's wort) is unavoidable .

CYP1A2 Inducers and Cigarette Smoking

Cigarette smoking decreased Tarceva exposure. Avoid smoking tobacco (CYP1A2 inducer) and avoid concomitant use of Tarceva with moderate CYP1A2 inducers (e.g., teriflunomide, rifampin, or phenytoin). Increase the Tarceva dosage in patients that smoke tobacco or when co-administration with moderate CYP1A2 inducers is unavoidable .

Drugs the Increase Gastric pH

Co-administration of Tarceva with proton pump inhibitors (e.g., omeprazole) and H-2 receptor antagonists (e.g., ranitidine) decreased Tarceva exposure . For proton pump inhibitors, avoid concomitant use if possible. For H-2 receptor antagonists and antacids, modify the dosing schedule . Increasing the dose of Tarceva when co-administered with gastric PH elevating agents is not likely to compensate for the loss of exposure.

Anticoagulants

Interaction with coumarin-derived anticoagulants, including warfarin, leading to increased International Normalized Ratio (INR) and bleeding adverse reactions, which in some cases were fatal, have been reported in patients receiving Tarceva. Regularly monitor prothrombin time or INR in patients taking coumarin-derived anticoagulants. Dose modifications of Tarceva are not recommended .

8 USE IN SPECIFIC POPULATIONS

Lactation: Do not breastfeed

8.1 Pregnancy

Risk Summary

Based on animal data and its mechanism of action, Tarceva can cause fetal harm when administered to a pregnant woman. Limited available data on use of Tarceva in pregnant women are not sufficient to inform a risk of major birth defects or miscarriage. When given during organogenesis, Tarceva administration resulted in embryo-fetal lethality and abortion in rabbits at exposures approximately 3 times the exposure at the recommended human daily dose of 150 mg. 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 2-4% and 15-20%, respectively.

Data

Animal Data

Tarceva has been shown to cause maternal toxicity resulting in embryo-fetal lethality and abortion in rabbits when given during the period of organogenesis at doses that result in plasma drug concentrations approximately 3 times those achieved at the recommended dose in humans (AUCs at 150 mg daily dose). During the same period, there was no increase in the incidence of embryo-fetal lethality or abortion in rabbits or rats at doses resulting in exposures approximately equal to those in humans at the recommended daily dose. In an independent fertility study female rats treated with 30 mg/m2/day or 60 mg/m2/day (0.3 or 0.7 times the recommended daily dose, on a mg/m2 basis) of Tarceva had an increase in early resorptions that resulted in a decrease in the number of live fetuses.

No teratogenic effects were observed in rabbits or rats dosed with Tarceva during organogenesis at doses up to 600 mg/m2/day in the rabbit (3 times the plasma drug concentration seen in humans at 150 mg/day) and up to 60 mg/m2/day in the rat (0.7 times the recommended dose of 150 mg/day on a mg/m2 basis).

8.2 Lactation

Risk Summary

There are no data on the presence of Tarceva in human milk, or the effects of Tarceva on the breastfed infant or on milk production. Because of the potential for serious adverse reactions in breastfed infants from Tarceva, including interstitial lung disease, hepatotoxicity, bullous and exfoliative skin disorders, microangiopathic hemolytic anemia with thrombocytopenia, ocular disorders, and diarrhea. Advise a lactating woman not to breastfeed during treatment with Tarceva and for 2 weeks after the final dose.

8.3 Females and Males of Reproductive Potential

Contraception

Females

Tarceva can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations ]. Advise females of reproductive potential to use effective contraception during treatment with Tarceva and for one month after the last dose of Tarceva.

8.4 Pediatric Use

The safety and effectiveness of Tarceva in pediatric patients have not been established.

In an open-label, multicenter trial, 25 pediatric patients (median age 14 years, range 3-20 years) with recurrent or refractory ependymoma were randomized (1:1) to Tarceva or etoposide. Thirteen patients received Tarceva at a dose of 85 mg/m2/day orally until disease progression, death, patient request, investigator decision to discontinue study drug, or intolerable toxicity. Four patients randomized to etoposide also received Tarceva following disease progression. The trial was terminated prematurely for lack of efficacy; there were no objective responses observed in these 17 TARCEVA-treated patients.

No new adverse events were identified in the pediatric population.

Based on the population pharmacokinetics analysis conducted in 105 pediatric patients (2 to 21 years old) with cancer, the geometric mean estimates of CL/F/BSA (apparent clearance normalized to body surface area) were comparable across the three age groups: 2-6 years (n = 29), 7-16 years (n = 59), and 17-21 years (n = 17).

8.5 Geriatric Use

Of the 1297 subjects in clinical studies of Tarceva for the treatment of NSCLC and pancreatic cancer 40% were 65 and older while 10% were 75 and older. No overall differences in safety or efficacy were observed between subjects 65 years and older and those younger than 65.

8.6 Hepatic Impairment

Hepatic failure and hepatorenal syndrome, including fatal cases, can occur with Tarceva treatment in patients with normal hepatic function; the risk of hepatic toxicity is increased in patients with baseline hepatic impairment . Monitor patients with hepatic impairment (total bilirubin greater than upper limit of normal (ULN) or Child-Pugh A, B and C) during therapy with Tarceva. Treatment with Tarceva should be used with increased monitoring in patients with total bilirubin greater than 3 x ULN .

10 OVERDOSAGE

Withhold Tarceva in patients with an overdose or suspected overdose and institute symptomatic treatment.

11 DESCRIPTION

Tarceva, a kinase inhibitor, is a quinazolinamine with the chemical name N-(3-ethynylphenyl)-6,7-bis(2-methoxyethoxy)-4-quinazolinamine. Tarceva contains Tarceva as the hydrochloride salt that has the following structural formula:

In exploratory subgroup analyses based on EGFR mutation subtype, the hazard ratio (HR) for PFS was 0.27 (95% CI 0.17 to 0.43) in patients with exon 19 deletions and 0.52 (95% CI 0.29 to 0.95) in patients with exon 21 (L858R) substitution. The HR for OS was 0.94 (95% CI 0.57 to 1.54) in the exon 19 deletion subgroup and 0.99 (95% CI 0.56 to 1.76) in the exon 21 (L858R) substitution subgroup.

14.2 NSCLC – Lack of Efficacy of Tarceva in Maintenance Treatment of Patients without EGFR Mutations

Lack of efficacy of Tarceva for the maintenance treatment of patients with NSCLC without EGFR activating mutations was demonstrated in Study 2. Study 2 was a multicenter, placebo-controlled, randomized trial of 643 patients with advanced NSCLC without an EGFR exon 19 deletion or exon 21 L858R mutation who had not experienced disease progression after four cycles of platinum-based chemotherapy. Patients were randomized 1:1 to receive Tarceva 150 mg or placebo orally once daily (322 Tarceva, 321 placebo) until disease progression or unacceptable toxicity. Following progression on initial therapy, patients were eligible to enter an open-label phase. Baseline characteristics were as follows: median age 61 years (35% age ≥ 65 years), 75% male, 77% White, 21% Asian, 28% ECOG PS 0, 72% ECOG PS 1, 16% never smokers, 58% current smokers, 57% adenocarcinoma, 35% squamous cell carcinoma, 22% stage IIIB disease not amenable to combined modality treatment, and 78% stage IV disease. Fifty percent of patients randomized to Tarceva entered the open-label phase and received chemotherapy, while 77% of patients randomized to placebo entered the open-label phase and received Tarceva.

The main efficacy outcome was overall survival (OS). Median OS was 9.7 months in the Tarceva arm and 9.5 months in the placebo arm; the hazard ratio for OS was 1.02 (95% CI 0.85, 1.22). Median PFS was 3.0 months in the Tarceva arm and 2.8 months in the placebo arm; the hazard ratio for PFS was 0.94 (95% CI 0.80, 1.11).

14.3 NSCLC – Maintenance Treatment or Second/Third Line Treatment

Two randomized, double-blind, placebo-controlled trials, Studies 3 and 4, examined the efficacy and safety of Tarceva administered to patients with metastatic NSCLC as maintenance therapy after initial treatment with chemotherapy or with disease progression following initial treatment with chemotherapy (Study 4). Determination of EGFR mutation status was not required for enrollment.

Study 3

The efficacy and safety of Tarceva as maintenance treatment of NSCLC were demonstrated in Study 3, a randomized, double-blind, placebo-controlled trial conducted in 26 countries, in 889 patients with metastatic NSCLC whose disease did not progress during first-line platinum-based chemotherapy. Patients were randomized 1:1 to receive Tarceva 150 mg or placebo orally once daily (438 Tarceva, 451 placebo) until disease progression or unacceptable toxicity. The primary objective of the study was to determine if the administration of Tarceva after standard platinum-based chemotherapy in the treatment of NSCLC resulted in improved progression-free survival (PFS) when compared with placebo, in all patients or in patients with EGFR immunohistochemistry (IHC) positive tumors.

Baseline demographics of the overall study population were as follows: male (74%), age < 65 years (66%), ECOG PS 1 (69%), ECOG PS 0 (31%), white (84%), Asian (15%), current smoker (55%), past-smoker (27%), and never smoker (17%). Disease characteristics were as follows: Stage IV (75%), Stage IIIb with effusion (25%) as classified by AJCC (6th edition) with histologic subtypes of adenocarcinoma including bronchioalveolar (45%), squamous (40%) and large cell (5%); and EGFR IHC positive (70%), negative (14%), indeterminate (4%), and missing (12%).

Study 4

The efficacy and safety of single-agent Tarceva was assessed in Study 4, a randomized, double blind, placebo-controlled trial in 731 patients with locally advanced or metastatic NSCLC after failure of at least one chemotherapy regimen. Patients were randomized 2:1 to receive Tarceva 150 mg or placebo (488 Tarceva, 243 placebo) orally once daily until disease progression or unacceptable toxicity. Efficacy outcome measures included overall survival, response rate, and progression-free survival (PFS). Duration of response was also examined. The primary endpoint was survival. The study was conducted in 17 countries.

Baseline demographics of the overall study population were as follows: male (65%), White (78%), Asian (12%), Black (4%), age < 65 years (62%), ECOG PS 1 (53%), ECOG PS 0 (13%), ECOG PS 2 (25%), ECOG PS 3 (9%), current or ex-smoker (75%), never smoker (20%), and exposure to prior platinum therapy (93%). Tumor characteristics were as follows: adenocarcinoma (50%), squamous (30%), undifferentiated large cell (9%), and mixed non-small cell (2%).

14.4 NSCLC – Lack of Efficacy of Tarceva Administered Concurrently with Chemotherapy

Results from two, multicenter, placebo-controlled, randomized, trials in over 1000 patients conducted in first-line patients with locally advanced or metastatic NSCLC showed no clinical benefit with the concurrent administration of Tarceva with platinum-based chemotherapy [carboplatin and paclitaxel (TARCEVA, N = 526) or gemcitabine and cisplatin (TARCEVA, N = 580)].

14.5 Pancreatic Cancer - Tarceva Administered Concurrently with Gemcitabine

The efficacy and safety of Tarceva in combination with gemcitabine as a first-line treatment was assessed in Study 5, a randomized, double-blind, placebo-controlled trial in 569 patients with locally advanced, unresectable or metastatic pancreatic cancer. Patients were randomized 1:1 to receive Tarceva (100 mg or 150 mg) or placebo once daily on a continuous schedule plus gemcitabine by intravenous infusion (1000 mg/m2, Cycle 1 - Days 1, 8, 15, 22, 29, 36 and 43 of an 8-week cycle; Cycle 2 and subsequent cycles - Days 1, 8 and 15 of a 4-week cycle [the approved dose and schedule for pancreatic cancer, see the gemcitabine package insert]). Tarceva or placebo was taken orally once daily until disease progression or unacceptable toxicity. The primary endpoint was survival. Secondary endpoints included response rate, and progression-free survival (PFS). Duration of response was also examined. The study was conducted in 18 countries. A total of 285 patients were randomized to receive gemcitabine plus Tarceva (261 patients in the 100 mg cohort and 24 patients in the 150 mg cohort) and 284 patients were randomized to receive gemcitabine plus placebo (260 patients in the 100 mg cohort and 24 patients in the 150 mg cohort). Too few patients were treated in the 150 mg cohort to draw conclusions.

In the 100 mg cohort, baseline demographics of the overall study population were as follows: male (52%), white (88%), Asian (7%), black (2%), age < 65 years (53%), ECOG PS 1 (51%), ECOG PS 0 (32%), and ECOG PS 2 (17%). There was a slightly larger proportion of females in the Tarceva arm (51%) compared with the placebo arm (44%). The median time from initial diagnosis to randomization was approximately 1.0 month. The majority of the patients (76%) had distant metastases at baseline and 24% had locally advanced disease.

The results of the study are shown in Table 9.
