Adults The safety of dexlansoprazole delayed-release capsules was evaluated in 4548 adult patients in controlled and single-arm clinical trials, including 863 patients treated for at least six months and 203 patients treated for one year. Patients ranged in age from 18 to 90 years (median age 48 years), with 54% female, 85% Caucasian, 8% Black, 4% Asian, and 3% Other races. Six randomized controlled clinical trials were conducted for the treatment of EE, maintenance of healed EE, and symptomatic GERD, which included 896 patients on placebo, 455 patients on dexlansoprazole delayed-release capsules 30 mg, 2218 patients on dexlansoprazole delayed-release capsules 60 mg, and 1363 patients on lansoprazole 30 mg once daily. Common Adverse Reactions The most common adverse reactions (≥2%) that occurred at a higher incidence for dexlansoprazole delayed-release capsules than placebo in the controlled studies are presented in Table 2 .

11 DESCRIPTION The active ingredient in dexlansoprazole delayed-release capsules, a proton pump inhibitor, is (+)-2-[( R )-{[3-methyl-4-(2,2,2-trifluoroethoxy)pyridin-2-yl] methyl} sulfinyl]- 1H -benzimidazole, a compound that inhibits gastric acid secretion. Dexlansoprazole is the R -enantiomer of lansoprazole (a racemic mixture of the R - and S -enantiomers). Its empirical formula is: C 16 H 14 F 3 N 3 O 2 S, with a molecular weight of 369.36. Dexlansoprazole has the following chemical structure: Dexlansoprazole is a white to nearly white crystalline powder which melts with decomposition at 140°C. Dexlansoprazole is freely soluble in dimethylformamide, methanol, dichloromethane, ethanol, and ethyl acetate; and soluble in acetonitrile; slightly soluble in ether; and very slightly soluble in water; and practically insoluble in hexane. Dexlansoprazole is stable when exposed to light. Dexlansoprazole is more stable in neutral and alkaline conditions than acidic conditions. Dexlansoprazole is supplied for oral administration as a dual delayed-release formulation in capsules. The capsules contain dexlansoprazole in a mixture of two types of enteric-coated granules with different pH-dependent dissolution profiles [see Clinical Pharmacology (12.3) ] . Dexlansoprazole delayed-release capsules are available in two dosage strengths: 30 and 60 mg, per capsule. Each capsule contains enteric-coated granules consisting of dexlansoprazole (active ingredient) and the following inactive ingredients: sugar spheres, magnesium carbonate, sucrose, low-substituted hydroxypropyl cellulose, titanium dioxide, hydroxypropyl cellulose, hypromellose 2910, talc, methacrylic acid copolymers, polyethylene glycol 8000, triethyl citrate, polysorbate 80, and colloidal silicon dioxide. The components of the capsule shell include the following inactive ingredients: hypromellose, carrageenan and potassium chloride. Based on the capsule shell color, blue contains FD&C Blue No. 2 (or FD&C Blue No. 2 aluminum lake); gray contains black ferric oxide; and both contain titanium dioxide. Chemical Structure

Nonserious adverse reactions observed with twice daily doses of dexlansoprazole delayed-release capsules 60 mg include hot flashes, contusion, oropharyngeal pain, and weight loss. Dexlansoprazole is not expected to be removed from the circulation by hemodialysis. In the event of over-exposure, treatment should be symptomatic and supportive. If over-exposure occurs, call your poison control center at 1-800-222-1222 for current information on the management of poisoning or over-exposure.

7 DRUG INTERACTIONS Tables 3 and 4 include drugs with clinically important drug interactions and interaction with diagnostics when administered concomitantly with dexlansoprazole delayed-release capsules and instructions for preventing or managing them. Consult the labeling of concomitantly used drugs to obtain further information about interactions with PPIs. Table 3. Clinically Relevant Interactions Affecting Drugs Co-Administered with Dexlansoprazole Delayed-Release Capsules and Interactions with Diagnostics Antiretrovirals Clinical Impact: The effect of PPIs on antiretroviral drugs is variable. The clinical importance and the mechanisms behind these interactions are not always known. Decreased exposure of some antiretroviral drugs (e.g., rilpivirine, atazanavir, and nelfinavir) when used concomitantly with dexlansoprazole may reduce antiviral effect and promote the development of drug resistance . Increased exposure of other antiretroviral drugs (e.g., saquinavir) when used concomitantly with dexlansoprazole may increase toxicity of the antiretroviral drugs. There are other antiretroviral drugs which do not result in clinically relevant interactions with dexlansoprazole. Intervention: Rilpivirine-containing products : Concomitant use with dexlansoprazole delayed-release capsules is contraindicated [see Contraindications (4) ] . See prescribing information. Atazanavir : See prescribing information for atazanavir for dosing information. Nelfinavir : Avoid concomitant use with dexlansoprazole delayed-release capsules. See prescribing information for nelfinavir. Saquinavir : See the prescribing information for saquinavir and monitor for potential saquinavir toxicities. Other antiretrovirals : See prescribing information. Warfarin Clinical Impact: Increased INR and prothrombin time in patients receiving PPIs and warfarin concomitantly. Increases in INR and prothrombin time may lead to abnormal bleeding and even death. Intervention: Monitor INR and prothrombin time. Dose adjustment of warfarin may be needed to maintain target INR range. See prescribing information for warfarin. Methotrexate Clinical Impact: Concomitant use of PPIs with methotrexate (primarily at high dose) may elevate and prolong serum concentrations of methotrexate and/or its metabolite hydroxymethotrexate, possibly leading to methotrexate toxicities. No formal drug interaction studies of high-dose methotrexate with PPIs have been conducted [see Warnings and Precautions (5.10) ] . Intervention: A temporary withdrawal of dexlansoprazole delayed-release capsules may be considered in some patients receiving high-dose methotrexate. Digoxin Clinical Impact: Potential for increased exposure of digoxin. Intervention: Monitor digoxin concentrations. Dose adjustment of digoxin may be needed to maintain therapeutic drug concentrations. See prescribing information for digoxin. Drugs Dependent on Gastric pH for Absorption (e.g., iron salts, erlotinib, dasatinib, nilotinib, mycophenolate mofetil, ketoconazole/itraconazole) Clinical Impact: Dexlansoprazole can reduce the absorption of other drugs due to its effect on reducing intragastric acidity. Intervention: Mycophenolate mofetil (MMF): Coadministration of PPIs in healthy subjects and in transplant patients receiving MMF has been reported to reduce the exposure to the active metabolite, mycophenolic acid (MPA), possibly due to a decrease in MMF solubility at an increased gastric pH. The clinical relevance of reduced MPA exposure on organ rejection has not been established in transplant patients receiving dexlansoprazole delayed-release capsules and MMF. Use dexlansoprazole delayed-release capsules with caution in transplant patients receiving MMF. See the prescribing information for other drugs dependent on gastric pH for absorption. Tacrolimus Clinical Impact: Potentially increased exposure of tacrolimus, especially in transplant patients who are intermediate or poor metabolizers of CYP2C19 . Intervention: Monitor tacrolimus whole blood trough concentrations. Dose adjustment of tacrolimus may be needed to maintain therapeutic drug concentrations. See prescribing information for tacrolimus. Interactions with Investigations of Neuroendocrine Tumors Clinical Impact: CgA levels increase secondary to PPI-induced decreases in gastric acidity. The increased CgA level may cause false positive results in diagnostic investigations for neuroendocrine tumors [see Warnings and Precautions (5.9) , Clinical Pharmacology (12.2) ] . Intervention: Temporarily stop dexlansoprazole delayed-release capsules treatment at least 14 days before assessing CgA levels and consider repeating the test if initial CgA levels are high. If serial tests are performed (e.g., for monitoring), the same commercial laboratory should be used for testing, as reference ranges between tests may vary. Interaction with Secretin Stimulation Test Clinical Impact: Hyper-response in gastrin secretion in response to secretin stimulation test, falsely suggesting gastrinoma. Intervention: Temporarily stop dexlansoprazole delayed-release capsules treatment at least 30 days before assessing to allow gastrin levels to return to baseline [see Clinical Pharmacology (12.2) ] . False Positive Urine Tests for THC Clinical Impact: There have been reports of false positive urine screening tests for tetrahydrocannabinol (THC) in patients receiving PPIs. Intervention: An alternative confirmatory method should be considered to verify positive results. Table 4. Clinically Relevant Interactions Affecting Dexlansoprazole Delayed-Release Capsules When Co-Administered with Other Drugs and Substances CYP2C19 or CYP3A4 Inducers Clinical Impact: Decreased exposure of dexlansoprazole when used concomitantly with strong inducers [see Clinical Pharmacology (12.3) ] . Intervention: St. John's Wort, rifampin : Avoid concomitant use with dexlansoprazole delayed-release capsules. Ritonavir-containing products : See prescribing information. CYP2C19 or CYP3A4 Inhibitors Clinical Impact: Increased exposure of dexlansoprazole is expected when used concomitantly with strong inhibitors [see Clinical Pharmacology (12.3) ] . Intervention: Voriconazole : See prescribing information. See full prescribing information for a list of clinically important drug interactions. ( 7 )

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Dexlansoprazole belongs to a class of antisecretory compounds, the substituted benzimidazoles, that suppress gastric acid secretion by specific inhibition of the (H + , K + )-ATPase at the secretory surface of the gastric parietal cell. Because this enzyme is regarded as the acid (proton) pump within the parietal cell, dexlansoprazole has been characterized as a gastric proton-pump inhibitor, in that it blocks the final step of acid production. 12.2 Pharmacodynamics Antisecretory Activity The effects of dexlansoprazole delayed-release capsules 60 mg (n=20) or lansoprazole 30 mg (n=23) once daily for five days on 24 hour intragastric pH were assessed in healthy subjects in a multiple-dose crossover study. The results are summarized in Table 5 . Table 5. Effect on 24 Hour Intragastric pH on Day 5 After Administration of Dexlansoprazole Delayed-Release Capsules or Lansoprazole Dexlansoprazole Delayed-Release Capsules 60 mg Lansoprazole 30 mg Mean Intragastric pH 4.55 4.13 % Time Intragastric pH >4 (hours) 71 (17 hours) 60 (14 hours) Serum Gastrin Effects The effect of dexlansoprazole on serum gastrin concentrations was evaluated in approximately 3460 patients in clinical trials up to eight weeks and in 1023 patients for up to six to 12 months. The mean fasting gastrin concentrations increased from baseline during treatment with 30 and 60 mg dexlansoprazole delayed-release capsules. In patients treated for more than six months, mean serum gastrin levels increased during approximately the first three months of treatment and were stable for the remainder of treatment. Mean serum gastrin levels returned to pretreatment levels within one month of discontinuation of treatment. Increased gastrin causes enterochromaffin-like cell hyperplasia and increased serum CgA levels. The increased CgA levels may cause false positive results in diagnostic investigations for neuroendocrine tumors [see Warnings and Precautions (5.9) ] . Enterochromaffin-Like Cell (ECL) Effects There were no reports of ECL cell hyperplasia in gastric biopsy specimens obtained from 653 patients treated with dexlansoprazole delayed-release capsules 30, 60, or 90 mg for up to 12 months. During lifetime exposure of rats dosed daily with up to 150 mg/kg/day of lansoprazole, marked hypergastrinemia was observed followed by ECL cell proliferation and formation of carcinoid tumors, especially in female rats [see Nonclinical Toxicology (13.1) ] . Cardiac Electrophysiology At a dose five times the maximum recommended dose, dexlansoprazole does not prolong the QT interval to any clinically relevant extent. 12.3 Pharmacokinetics The dual delayed-release formulation of dexlansoprazole capsules results in a dexlansoprazole plasma concentration-time profile with two distinct peaks; the first peak occurs one to two hours after administration, followed by a second peak within four to five hours (see Figure 1 ) . Dexlansoprazole is eliminated with a half-life of approximately one to two hours in healthy subjects and in patients with symptomatic GERD. No accumulation of dexlansoprazole occurs after multiple, once daily doses of dexlansoprazole delayed-release capsules 30 or 60 mg although mean AUC t and C max values of dexlansoprazole were slightly higher (less than 10%) on Day 5 than on Day 1. Figure 1: Mean Plasma Dexlansoprazole Concentration – Time Profile Following Oral Administration of 30 or 60 mg Dexlansoprazole Delayed-Release Capsules Once Daily for 5 Days in Healthy Adult Subjects The pharmacokinetics of dexlansoprazole are highly variable, with percent coefficient of variation (%CV) values for C max , AUC, and CL/F of greater than 30% (see Table 6 ) . Table 6. Mean (%CV) Pharmacokinetic Parameters for Adult Subjects on Day 5 After Administration of Dexlansoprazole Delayed-Release Capsules Dose (mg) C max (ng/mL) AUC 24 (ng∙h/mL) CL/F (L/h) 30 658 (40%) (N=44) 3275 (47%) (N=43) 11.4 (48%) (N=43) 60 1397 (51%) (N=79) 6529 (60%) (N=73) 11.6 (46%) (N=41) Absorption After oral administration of dexlansoprazole delayed-release capsules 30 or 60 mg to healthy subjects and symptomatic GERD patients, mean C max and AUC values of dexlansoprazole increased approximately dose proportionally (see Figure 1 ) . When granules of dexlansoprazole delayed-release capsules 60 mg are mixed with water and dosed via NG tube or orally via syringe, the bioavailability (C max and AUC) of dexlansoprazole was similar to that when dexlansoprazole delayed-release capsules 60 mg was administered as an intact capsule [see Dosage and Administration (2.3) ] . Effect on Food In food-effect studies in healthy subjects receiving dexlansoprazole delayed-release capsules under various fed conditions compared to fasting, increases in C max ranged from 12 to 55%, increases in AUC ranged from 9 to 37%, and T max varied (ranging from a decrease of 0.7 hours to an increase of three hours) [see Dosage and Administration (2.3) ] . Distribution Plasma protein binding of dexlansoprazole ranged from 96 to 99% in healthy subjects and was independent of concentration from 0.01 to 20 mcg/mL. The apparent volume of distribution (V z /F) after multiple doses in symptomatic GERD patients was 40 L. Elimination Metabolism Dexlansoprazole is extensively metabolized in the liver by oxidation, reduction, and subsequent formation of sulfate, glucuronide and glutathione conjugates to inactive metabolites. Oxidative metabolites are formed by the cytochrome P450 (CYP) enzyme system including hydroxylation mainly by CYP2C19, and oxidation to the sulfone by CYP3A4. CYP2C19 is a polymorphic liver enzyme which exhibits three phenotypes in the metabolism of CYP2C19 substrates: extensive metabolizers (*1/*1), intermediate metabolizers (*1/mutant) and poor metabolizers (mutant/mutant). Dexlansoprazole is the major circulating component in plasma regardless of CYP2C19 metabolizer status. In CYP2C19 intermediate and extensive metabolizers, the major plasma metabolites are 5-hydroxy dexlansoprazole and its glucuronide conjugate, while in CYP2C19 poor metabolizers dexlansoprazole sulfone is the major plasma metabolite. Excretion Following the administration of dexlansoprazole delayed-release capsules, no unchanged dexlansoprazole is excreted in urine. Following the administration of [ 14 C] dexlansoprazole to six healthy male subjects, approximately 50.7% (standard deviation (SD): 9.0%) of the administered radioactivity was excreted in urine and 47.6% (SD: 7.3%) in the feces. Apparent clearance (CL/F) in healthy subjects was 11.4 to 11.6 L/hour, respectively, after five days of 30 or 60 mg once daily administration. Specific Populations Age: Pediatric Population The pharmacokinetics of dexlansoprazole in patients under the age of 12 years have not been studied. Patients 12 to 17 Years of Age The pharmacokinetics of dexlansoprazole were studied in 36 patients 12 to 17 years of age with symptomatic GERD in a multicenter trial. Patients were randomized to receive dexlansoprazole delayed-release capsules 30 or 60 mg once daily for seven days. The dexlansoprazole mean C max and AUC in patients 12 to 17 years of age were 105 and 88%, respectively, compared to those observed in adults at the 30 mg dose, and were 81 and 78%, respectively, at the 60 mg dose (see Tables 6 and 7 ) . Table 7. Mean (%CV) Pharmacokinetic Parameters in Patients 12 to 17 Years of Age with Symptomatic GERD on Day 7 After Administration of Dexlansoprazole Delayed-Release Capsules Once Daily for 7 Days Dose C max (ng/mL) AUC tau (ng∙h/mL) CL/F (L/h) 30 mg (N=17) 691 (53) 2886 (47) 12.8 (48) 60 mg (N=18) 1136 (51) 5120 (58) 15.3 (49) Age: Geriatric Population The terminal elimination half-life of dexlansoprazole is significantly increased in geriatric subjects compared to younger subjects (2.2 and 1.5 hours, respectively). Dexlansoprazole exhibited higher systemic exposure (AUC) in geriatric subjects (34% higher) than younger subjects [see Use in Specific Populations (8.5) ] . Sex In a study of 12 male and 12 female healthy subjects who received a single dose of dexlansoprazole delayed-release capsules 60 mg, females had higher systemic exposure (AUC) (43% higher) than males. This difference in exposure between males and females does not represent a significant safety concern. Renal Impairment Dexlansoprazole is extensively metabolized in the liver to inactive metabolites, and no parent drug is recovered in the urine following an oral dose of dexlansoprazole. Therefore, the pharmacokinetics of dexlansoprazole are not expected to be altered in patients with renal impairment, and no studies were conducted in patients with renal impairment. In addition, the pharmacokinetics of lansoprazole were not clinically different in patients with mild, moderate or severe renal impairment compared to healthy subjects with normal renal function. Hepatic Impairment In a study of 12 patients with moderate hepatic impairment (Child-Pugh Class B) who received a single dose of 60 mg dexlansoprazole delayed-release capsules, the systemic exposure (AUC) of bound and unbound dexlansoprazole was approximately two times greater compared to subjects with normal hepatic function. This difference in exposure was not due to a difference in protein binding. No studies have been conducted in patients with severe hepatic impairment (Child-Pugh Class C) [see Dosage and Administration (2.2) , Use in Specific Populations (8.6) ] . Drug-Drug Interactions Effect of Dexlansoprazole on Other Drugs Cytochrome P 450 Interactions Dexlansoprazole is metabolized, in part, by CYP2C19 and CYP3A4 [see Clinical Pharmacology (12.3) ] . In vitro studies have shown that dexlansoprazole is not likely to inhibit CYP isoforms 1A1, 1A2, 2A6, 2B6, 2C8, 2C9, 2D6, 2E1 or 3A4. As such, no clinically relevant interactions with drugs metabolized by these CYP enzymes would be expected. Furthermore, in vivo studies showed that dexlansoprazole delayed-release capsules did not have an impact on the pharmacokinetics of co-administered phenytoin (CYP2C9 substrate) or theophylline (CYP1A2 substrate). The subjects' CYP1A2 genotypes in the drug-drug interaction study with theophylline were not determined. Although in vitro studies indicated that dexlansoprazole delayed-release capsules has the potential to inhibit CYP2C19 in vivo , an in vivo drug- drug interaction study in mainly CYP2C19 extensive and intermediate metabolizers has shown that dexlansoprazole delayed-release capsules does not affect the pharmacokinetics of diazepam (CYP2C19 substrate). Clopidogrel Clopidogrel is metabolized to its active metabolite in part by CYP2C19. A study of healthy subjects who were CYP2C19 extensive metabolizers, receiving once daily administration of clopidogrel 75 mg alone or concomitantly with dexlansoprazole delayed-release capsules 60 mg (n=40), for nine days was conducted. The mean AUC of the active metabolite of clopidogrel was reduced by approximately 9% (mean AUC ratio was 91%, with 90% CI of 86 to 97%) when dexlansoprazole delayed-release capsules were co-administered compared to administration of clopidogrel alone. Pharmacodynamic parameters were also measured and demonstrated that the change in inhibition of platelet aggregation (induced by 5 mcM ADP) was related to the change in the exposure to clopidogrel active metabolite. The effect on exposure to the active metabolite of clopidogrel and on clopidogrel-induced platelet inhibition is not considered clinically important. Effect of Other Drugs on Dexlansoprazole Because dexlansoprazole is metabolized by CYP2C19 and CYP3A4, inducers and inhibitors of these enzymes may potentially alter exposure of dexlansoprazole. Figure 1 12.5 Pharmacogenomics Effect of CYP2C19 Polymorphism on Systemic Exposure of Dexlansoprazole Systemic exposure of dexlansoprazole is generally higher in intermediate and poor metabolizers. In male Japanese subjects who received a single dose of dexlansoprazole delayed-release capsules 30 or 60 mg (N=2 to 6 subjects/group), mean dexlansoprazole C max and AUC values were up to two times higher in intermediate compared to extensive metabolizers; in poor metabolizers, mean C max was up to four times higher and mean AUC was up to 12 times higher compared to extensive metabolizers. Though such study was not conducted in Caucasians and African Americans, it is expected dexlansoprazole exposure in these races will be affected by CYP2C19 phenotypes as well.

12.1 Mechanism of Action Dexlansoprazole belongs to a class of antisecretory compounds, the substituted benzimidazoles, that suppress gastric acid secretion by specific inhibition of the (H + , K + )-ATPase at the secretory surface of the gastric parietal cell. Because this enzyme is regarded as the acid (proton) pump within the parietal cell, dexlansoprazole has been characterized as a gastric proton-pump inhibitor, in that it blocks the final step of acid production.

12.2 Pharmacodynamics Antisecretory Activity The effects of dexlansoprazole delayed-release capsules 60 mg (n=20) or lansoprazole 30 mg (n=23) once daily for five days on 24 hour intragastric pH were assessed in healthy subjects in a multiple-dose crossover study. The results are summarized in Table 5 . Table 5. Effect on 24 Hour Intragastric pH on Day 5 After Administration of Dexlansoprazole Delayed-Release Capsules or Lansoprazole Dexlansoprazole Delayed-Release Capsules 60 mg Lansoprazole 30 mg Mean Intragastric pH 4.55 4.13 % Time Intragastric pH >4 (hours) 71 (17 hours) 60 (14 hours) Serum Gastrin Effects The effect of dexlansoprazole on serum gastrin concentrations was evaluated in approximately 3460 patients in clinical trials up to eight weeks and in 1023 patients for up to six to 12 months. The mean fasting gastrin concentrations increased from baseline during treatment with 30 and 60 mg dexlansoprazole delayed-release capsules. In patients treated for more than six months, mean serum gastrin levels increased during approximately the first three months of treatment and were stable for the remainder of treatment. Mean serum gastrin levels returned to pretreatment levels within one month of discontinuation of treatment. Increased gastrin causes enterochromaffin-like cell hyperplasia and increased serum CgA levels. The increased CgA levels may cause false positive results in diagnostic investigations for neuroendocrine tumors [see Warnings and Precautions (5.9) ] . Enterochromaffin-Like Cell (ECL) Effects There were no reports of ECL cell hyperplasia in gastric biopsy specimens obtained from 653 patients treated with dexlansoprazole delayed-release capsules 30, 60, or 90 mg for up to 12 months. During lifetime exposure of rats dosed daily with up to 150 mg/kg/day of lansoprazole, marked hypergastrinemia was observed followed by ECL cell proliferation and formation of carcinoid tumors, especially in female rats [see Nonclinical Toxicology (13.1) ] . Cardiac Electrophysiology At a dose five times the maximum recommended dose, dexlansoprazole does not prolong the QT interval to any clinically relevant extent.

12.3 Pharmacokinetics The dual delayed-release formulation of dexlansoprazole capsules results in a dexlansoprazole plasma concentration-time profile with two distinct peaks; the first peak occurs one to two hours after administration, followed by a second peak within four to five hours (see Figure 1 ) . Dexlansoprazole is eliminated with a half-life of approximately one to two hours in healthy subjects and in patients with symptomatic GERD. No accumulation of dexlansoprazole occurs after multiple, once daily doses of dexlansoprazole delayed-release capsules 30 or 60 mg although mean AUC t and C max values of dexlansoprazole were slightly higher (less than 10%) on Day 5 than on Day 1. Figure 1: Mean Plasma Dexlansoprazole Concentration – Time Profile Following Oral Administration of 30 or 60 mg Dexlansoprazole Delayed-Release Capsules Once Daily for 5 Days in Healthy Adult Subjects The pharmacokinetics of dexlansoprazole are highly variable, with percent coefficient of variation (%CV) values for C max , AUC, and CL/F of greater than 30% (see Table 6 ) . Table 6. Mean (%CV) Pharmacokinetic Parameters for Adult Subjects on Day 5 After Administration of Dexlansoprazole Delayed-Release Capsules Dose (mg) C max (ng/mL) AUC 24 (ng∙h/mL) CL/F (L/h) 30 658 (40%) (N=44) 3275 (47%) (N=43) 11.4 (48%) (N=43) 60 1397 (51%) (N=79) 6529 (60%) (N=73) 11.6 (46%) (N=41) Absorption After oral administration of dexlansoprazole delayed-release capsules 30 or 60 mg to healthy subjects and symptomatic GERD patients, mean C max and AUC values of dexlansoprazole increased approximately dose proportionally (see Figure 1 ) . When granules of dexlansoprazole delayed-release capsules 60 mg are mixed with water and dosed via NG tube or orally via syringe, the bioavailability (C max and AUC) of dexlansoprazole was similar to that when dexlansoprazole delayed-release capsules 60 mg was administered as an intact capsule [see Dosage and Administration (2.3) ] . Effect on Food In food-effect studies in healthy subjects receiving dexlansoprazole delayed-release capsules under various fed conditions compared to fasting, increases in C max ranged from 12 to 55%, increases in AUC ranged from 9 to 37%, and T max varied (ranging from a decrease of 0.7 hours to an increase of three hours) [see Dosage and Administration (2.3) ] . Distribution Plasma protein binding of dexlansoprazole ranged from 96 to 99% in healthy subjects and was independent of concentration from 0.01 to 20 mcg/mL. The apparent volume of distribution (V z /F) after multiple doses in symptomatic GERD patients was 40 L. Elimination Metabolism Dexlansoprazole is extensively metabolized in the liver by oxidation, reduction, and subsequent formation of sulfate, glucuronide and glutathione conjugates to inactive metabolites. Oxidative metabolites are formed by the cytochrome P450 (CYP) enzyme system including hydroxylation mainly by CYP2C19, and oxidation to the sulfone by CYP3A4. CYP2C19 is a polymorphic liver enzyme which exhibits three phenotypes in the metabolism of CYP2C19 substrates: extensive metabolizers (*1/*1), intermediate metabolizers (*1/mutant) and poor metabolizers (mutant/mutant). Dexlansoprazole is the major circulating component in plasma regardless of CYP2C19 metabolizer status. In CYP2C19 intermediate and extensive metabolizers, the major plasma metabolites are 5-hydroxy dexlansoprazole and its glucuronide conjugate, while in CYP2C19 poor metabolizers dexlansoprazole sulfone is the major plasma metabolite. Excretion Following the administration of dexlansoprazole delayed-release capsules, no unchanged dexlansoprazole is excreted in urine. Following the administration of [ 14 C] dexlansoprazole to six healthy male subjects, approximately 50.7% (standard deviation (SD): 9.0%) of the administered radioactivity was excreted in urine and 47.6% (SD: 7.3%) in the feces. Apparent clearance (CL/F) in healthy subjects was 11.4 to 11.6 L/hour, respectively, after five days of 30 or 60 mg once daily administration. Specific Populations Age: Pediatric Population The pharmacokinetics of dexlansoprazole in patients under the age of 12 years have not been studied. Patients 12 to 17 Years of Age The pharmacokinetics of dexlansoprazole were studied in 36 patients 12 to 17 years of age with symptomatic GERD in a multicenter trial. Patients were randomized to receive dexlansoprazole delayed-release capsules 30 or 60 mg once daily for seven days. The dexlansoprazole mean C max and AUC in patients 12 to 17 years of age were 105 and 88%, respectively, compared to those observed in adults at the 30 mg dose, and were 81 and 78%, respectively, at the 60 mg dose (see Tables 6 and 7 ) . Table 7. Mean (%CV) Pharmacokinetic Parameters in Patients 12 to 17 Years of Age with Symptomatic GERD on Day 7 After Administration of Dexlansoprazole Delayed-Release Capsules Once Daily for 7 Days Dose C max (ng/mL) AUC tau (ng∙h/mL) CL/F (L/h) 30 mg (N=17) 691 (53) 2886 (47) 12.8 (48) 60 mg (N=18) 1136 (51) 5120 (58) 15.3 (49) Age: Geriatric Population The terminal elimination half-life of dexlansoprazole is significantly increased in geriatric subjects compared to younger subjects (2.2 and 1.5 hours, respectively). Dexlansoprazole exhibited higher systemic exposure (AUC) in geriatric subjects (34% higher) than younger subjects [see Use in Specific Populations (8.5) ] . Sex In a study of 12 male and 12 female healthy subjects who received a single dose of dexlansoprazole delayed-release capsules 60 mg, females had higher systemic exposure (AUC) (43% higher) than males. This difference in exposure between males and females does not represent a significant safety concern. Renal Impairment Dexlansoprazole is extensively metabolized in the liver to inactive metabolites, and no parent drug is recovered in the urine following an oral dose of dexlansoprazole. Therefore, the pharmacokinetics of dexlansoprazole are not expected to be altered in patients with renal impairment, and no studies were conducted in patients with renal impairment. In addition, the pharmacokinetics of lansoprazole were not clinically different in patients with mild, moderate or severe renal impairment compared to healthy subjects with normal renal function. Hepatic Impairment In a study of 12 patients with moderate hepatic impairment (Child-Pugh Class B) who received a single dose of 60 mg dexlansoprazole delayed-release capsules, the systemic exposure (AUC) of bound and unbound dexlansoprazole was approximately two times greater compared to subjects with normal hepatic function. This difference in exposure was not due to a difference in protein binding. No studies have been conducted in patients with severe hepatic impairment (Child-Pugh Class C) [see Dosage and Administration (2.2) , Use in Specific Populations (8.6) ] . Drug-Drug Interactions Effect of Dexlansoprazole on Other Drugs Cytochrome P 450 Interactions Dexlansoprazole is metabolized, in part, by CYP2C19 and CYP3A4 [see Clinical Pharmacology (12.3) ] . In vitro studies have shown that dexlansoprazole is not likely to inhibit CYP isoforms 1A1, 1A2, 2A6, 2B6, 2C8, 2C9, 2D6, 2E1 or 3A4. As such, no clinically relevant interactions with drugs metabolized by these CYP enzymes would be expected. Furthermore, in vivo studies showed that dexlansoprazole delayed-release capsules did not have an impact on the pharmacokinetics of co-administered phenytoin (CYP2C9 substrate) or theophylline (CYP1A2 substrate). The subjects' CYP1A2 genotypes in the drug-drug interaction study with theophylline were not determined. Although in vitro studies indicated that dexlansoprazole delayed-release capsules has the potential to inhibit CYP2C19 in vivo , an in vivo drug- drug interaction study in mainly CYP2C19 extensive and intermediate metabolizers has shown that dexlansoprazole delayed-release capsules does not affect the pharmacokinetics of diazepam (CYP2C19 substrate). Clopidogrel Clopidogrel is metabolized to its active metabolite in part by CYP2C19. A study of healthy subjects who were CYP2C19 extensive metabolizers, receiving once daily administration of clopidogrel 75 mg alone or concomitantly with dexlansoprazole delayed-release capsules 60 mg (n=40), for nine days was conducted. The mean AUC of the active metabolite of clopidogrel was reduced by approximately 9% (mean AUC ratio was 91%, with 90% CI of 86 to 97%) when dexlansoprazole delayed-release capsules were co-administered compared to administration of clopidogrel alone. Pharmacodynamic parameters were also measured and demonstrated that the change in inhibition of platelet aggregation (induced by 5 mcM ADP) was related to the change in the exposure to clopidogrel active metabolite. The effect on exposure to the active metabolite of clopidogrel and on clopidogrel-induced platelet inhibition is not considered clinically important. Effect of Other Drugs on Dexlansoprazole Because dexlansoprazole is metabolized by CYP2C19 and CYP3A4, inducers and inhibitors of these enzymes may potentially alter exposure of dexlansoprazole.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility The carcinogenic potential of dexlansoprazole was assessed using lansoprazole studies. In two, 24 month carcinogenicity studies, Sprague-Dawley rats were treated orally with lansoprazole at doses of 5 to 150 mg/kg/day, about one to 40 times the exposure on a body surface (mg/m 2 ) basis of a 50 kg person of average height [1.46 m 2 body surface area (BSA)] given the recommended human dose of lansoprazole 30 mg/day. Lansoprazole produced dose-related gastric ECL cell hyperplasia and ECL cell carcinoids in both male and female rats [see Clinical Pharmacology (12.2) ] . In rats, lansoprazole also increased the incidence of intestinal metaplasia of the gastric epithelium in both sexes. In male rats, lansoprazole produced a dose-related increase of testicular interstitial cell adenomas. The incidence of these adenomas in rats receiving doses of 15 to 150 mg/kg/day (four to 40 times the recommended human lansoprazole dose based on BSA) exceeded the low background incidence (range = 1.4 to 10%) for this strain of rat. In a 24 month carcinogenicity study, CD-1 mice were treated orally with lansoprazole doses of 15 to 600 mg/kg/day, two to 80 times the recommended human lansoprazole dose based on BSA. Lansoprazole produced a dose-related increased incidence of gastric ECL cell hyperplasia. It also produced an increased incidence of liver tumors (hepatocellular adenoma plus carcinoma). The tumor incidences in male mice treated with 300 and 600 mg lansoprazole/kg/day (40 to 80 times the recommended human lansoprazole dose based on BSA) and female mice treated with 150 to 600 mg lansoprazole/kg/day (20 to 80 times the recommended human lansoprazole dose based on BSA) exceeded the ranges of background incidences in historical controls for this strain of mice. Lansoprazole treatment produced adenoma of rete testis in male mice receiving 75 to 600 mg/kg/day (10 to 80 times the recommended human lansoprazole dose based on BSA). A 26 week p53 (+/-) transgenic mouse carcinogenicity study of lansoprazole was not positive. Lansoprazole was positive in the Ames test and the in vitro human lymphocyte chromosomal aberration assay. Lansoprazole was not genotoxic in the ex vivo rat hepatocyte unscheduled DNA synthesis (UDS) test, the in vivo mouse micronucleus test or the rat bone marrow cell chromosomal aberration test. Dexlansoprazole was positive in the Ames test and in the in vitro chromosome aberration test using Chinese hamster lung cells. Dexlansoprazole was negative in the in vivo mouse micronucleus test. The potential effects of dexlansoprazole on fertility and reproductive performance were assessed using lansoprazole studies. Lansoprazole at oral doses up to 150 mg/kg/day (40 times the recommended human lansoprazole dose based on BSA) was found to have no effect on fertility and reproductive performance of male and female rats.

13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility The carcinogenic potential of dexlansoprazole was assessed using lansoprazole studies.

MEDICATION GUIDE Dexlansoprazole (DEX lan SOE pra zol) delayed-release capsules, for oral use This Medication Guide has been approved by the U.S. Food and Drug Administration. Revised: 5/2023 Read this Medication Guide before you start taking dexlansoprazole delayed-release capsules and each time you get a refill. There may be new information. This information does not take the place of talking to your doctor about your medical condition or your treatment. What is the most important information that I should know about dexlansoprazole delayed-release capsules? Dexlansoprazole delayed-release capsules may help your acid-related symptoms, but you could still have serious stomach problems. Talk with your doctor. Dexlansoprazole delayed-release capsules can cause serious side effects, including: A type of kidney problem (acute tubulointerstitial nephritis). Some people who take proton pump inhibitor (PPI) medicines, including dexlansoprazole delayed-release capsules, may develop a kidney problem called acute tubulointerstitial nephritis, that can happen at any time during treatment with PPI medicines. Call your doctor right away if you have a decrease in the amount that you urinate or if you have blood in your urine. Diarrhea. Dexlansoprazole delayed-release capsules may increase your risk of getting severe diarrhea. This diarrhea may be caused by an infection ( Clostridium difficile ) in your intestines. Call your doctor right away if you have watery stool, stomach pain, and fever that does not go away. Bone fractures. People who take multiple daily doses of PPI medicines for a long period of time (a year or longer) may have an increased risk of fractures of the hip, wrist or spine. You should take dexlansoprazole delayed-release capsules exactly as prescribed, at the lowest dose possible for your treatment and for the shortest time needed. Talk to your doctor about your risk of bone fracture if you take dexlansoprazole delayed-release capsules. Certain types of lupus erythematosus. Lupus erythematosus is an autoimmune disorder (the body's immune cells attack other cells or organs in the body). Some people who take PPI medicines may develop certain types of lupus erythematosus or have worsening of the lupus they already have. Call your doctor right away if you have new or worsening joint pain or a rash on your cheeks or arms that gets worse in the sun. Dexlansoprazole delayed-release capsules can have other serious side effects. See " What are the possible side effects of dexlansoprazole delayed-release capsules? ". What are dexlansoprazole delayed-release capsules? Dexlansoprazole delayed-release capsules are prescription medicine called a proton pump inhibitor (PPI). Dexlansoprazole delayed-release capsules reduce the amount of acid in your stomach. Dexlansoprazole delayed-release capsules are used in people 12 years of age and older: for up to 8 weeks to heal acid-related damage to the lining of the esophagus (called erosive esophagitis or EE) for up to 6 months in adults and up to 16 weeks in children 12 to 17 years of age to continue healing of erosive esophagitis and relief of heartburn for 4 weeks to treat heartburn related to gastroesophageal reflux disease (GERD) GERD happens when acid from your stomach enters the tube (esophagus) that connects your mouth to your stomach. This may cause a burning feeling in your chest or throat, sour taste or burping. It is not known if dexlansoprazole delayed-release capsules are safe and effective in children under 12 years of age. Dexlansoprazole delayed-release capsules are not recommended in children under 2 years of age and may harm them.

14 CLINICAL STUDIES 14.1 Healing of Erosive Esophagitis in Adults Two multicenter, double-blind, active-controlled, randomized, eight week studies were conducted in patients with endoscopically confirmed EE. Severity of the disease was classified based on the Los Angeles Classification Grading System (Grades A-D). Patients were randomized to one of the following three treatment groups: dexlansoprazole delayed-release capsules 60 mg once daily, dexlansoprazole delayed-release capsules 90 mg once daily or lansoprazole 30 mg once daily. Patients who were H. pylori positive or who had Barrett's Esophagus and/or definite dysplastic changes at baseline were excluded from these studies. A total of 4092 patients were enrolled and ranged in age from 18 to 90 years (median age 48 years) with 54% male. Race was distributed as follows: 87% Caucasian, 5% Black and 8% Other. Based on the Los Angeles Classification, 71% of patients had mild EE (Grades A and B) and 29% of patients had moderate to severe EE (Grades C and D) before treatment. The studies were designed to test noninferiority. If noninferiority was demonstrated then superiority would be tested. Although noninferiority was demonstrated in both studies, the finding of superiority in one study was not replicated in the other. The proportion of patients with healed EE at Week 4 or 8 is presented below in Table 8 . Table 8. EE Healing Rates Based on crude rate estimates, patients who did not have endoscopically documented healed EE and prematurely discontinued were considered not healed. in Adults: All Grades Study Number of Patients (N) Patients with at least one postbaseline endoscopy.

Maintenance of healing and symptom resolution over a six month period was evaluated with dexlansoprazole delayed-release capsules 30 or 60 mg once daily compared to placebo. A total of 445 patients were enrolled and ranged in age from 18 to 85 years (median age 49 years), with 52% female. Race was distributed as follows: 90% Caucasian, 5% Black and 5% Other. Sixty-six percent of patients treated with 30 mg of dexlansoprazole delayed-release capsules remained healed over the six month time period as confirmed by endoscopy (see Table 9 ) . Table 9. Maintenance Rates Based on crude rate estimates, patients who did not have endoscopically documented relapse and prematurely discontinued were considered to have relapsed. of Healed EE at Month 6 in Adults Number of Patients (N) Patients with at least one postbaseline endoscopy Treatment Group (daily) Maintenance Rate (%) 125 Dexlansoprazole Delayed-Release Capsules 30 mg 66.4 Statistically significant vs placebo 119 Placebo 14.3 Dexlansoprazole delayed-release capsules 60 mg once daily was studied and did not provide additional clinical benefit over dexlansoprazole delayed-release capsules 30 mg once daily. The effect of dexlansoprazole delayed-release capsules 30 mg on maintenance of relief of heartburn was also evaluated. Upon entry into the maintenance study, a majority of patients' baseline heartburn severity was rated as none. Dexlansoprazole delayed-release capsules 30 mg demonstrated a statistically significantly higher percent of 24 hour heartburn-free periods compared to placebo over the six month treatment period (see Table 10 ) . The majority of patients treated with placebo discontinued due to relapse of EE between Month 2 and Month 6. Table 10.

These patients who identified heartburn as their primary symptom, had a history of heartburn for six months or longer, had heartburn on at least four of seven days immediately prior to randomization and had no esophageal erosions as confirmed by endoscopy. However, patients with symptoms which were not acid-related may not have been excluded using these inclusion criteria. Patients were randomized to one of the following treatment groups: dexlansoprazole delayed-release capsules 30 mg daily, 60 mg daily, or placebo. A total of 947 patients were enrolled and ranged in age from 18 to 86 years (median age 48 years) with 71% female. Race was distributed as follows: 82% Caucasian, 14% Black and 4% Other. Dexlansoprazole delayed-release capsules 30 mg provided statistically significantly greater percent of days with heartburn-free 24 hour periods over placebo as assessed by daily diary over four weeks (see Table 11 ) . Dexlansoprazole delayed-release capsules 60 mg once daily was studied and provided no additional clinical benefit over dexlansoprazole delayed-release capsules 30 mg once daily. Table 11.

Healing of EE, Maintenance of Healed EE and Relief of Heartburn In a multicenter, 36 week trial, 62 patients 12 to 17 years of age with a documented history of GERD for at least three months and endoscopically-proven erosive esophagitis (EE) were enrolled to evaluate the healing of EE, maintenance of healed EE and relief of heartburn, followed by an additional 12 weeks without treatment. The median age was 15 years, with males accounting for 61% of the patients. Based on the Los Angeles Classification Grading Scale, 97% of patients had mild EE (Grades A and B), and 3% of patients had moderate to severe EE (Grades C and D) before treatment. In the first eight weeks, 62 patients were treated with dexlansoprazole delayed-release capsules 60 mg once daily to evaluate the healing of EE. Of the 62 patients, 58 patients completed the eight week trial, and 51 (88%) patients achieved healing of EE, as confirmed by endoscopy, over eight weeks of treatment (see Table 12 ) . Table 12. Healing of EE at Week 8 in Pediatric Patients 12 to 17 Years of Age Dexlansoprazole Delayed-Release Capsules 60 mg Proportion of randomized patients healed n (%) 51/62 (82%) 95% CI (70, 91) Reported are the exact confidence limits. Proportion of evaluable patients healed Includes only patients who underwent postbaseline endoscopy. n (%) 51/58 (88%) 95% CI (77, 95) After the initial eight weeks of treatment, all 51 patients with healed EE were randomized to receive treatment with dexlansoprazole delayed-release capsules 30 mg or placebo, once daily for an additional 16 weeks to evaluate maintenance of healing and symptom resolution. Maintenance of healing was assessed by endoscopy at Week 24. Of the 51 patients randomized, 13 patients discontinued early. Of these, five patients did not undergo postbaseline endoscopy. Eighteen of 22 (82%) evaluable patients treated with dexlansoprazole delayed-release capsules 30 mg remained healed over the 16 week treatment period as confirmed by endoscopy, compared with 14 of 24 (58%) in placebo (see Table 13 ) . Table 13. Maintenance of Healed EE at Week 24 Following eight weeks of initial therapy and 16 weeks of maintenance therapy. in Pediatric Patients 12 to 17 Years of Age Dexlansoprazole Delayed-Release Capsules 30 mg Placebo Proportion of randomized patients who maintained healing of EE 18/25 (72%) 14/26 (54%) n (%) 95% Cl (51, 88) Reported are the exact confidence limits.

The median percentage of 24 hour heartburn-free periods was 87% for those receiving dexlansoprazole delayed-release capsules 30 mg compared to 68% for those receiving placebo. Out of the 32 patients who maintained healing of EE at the end of the 16 week maintenance period, 27 patients (16 treated with dexlansoprazole delayed-release capsules and 11 treated with placebo during the double-blind phase) were followed for an additional 12 weeks without therapy. Twenty-four of the 27 patients completed the 12 week follow-up period. One patient required treatment with acid suppression therapy. Treatment of Symptomatic Non-Erosive GERD In a single-arm, open-label, multicenter trial, 104 pediatric patients 12 to 17 years of age with symptomatic non-erosive GERD were treated with dexlansoprazole delayed-release capsules 30 mg once daily, for four weeks to evaluate safety and effectiveness. Patients had a documented history of GERD symptoms for at least three months prior to screening, reported heartburn on at least three out of seven days during screening, and had no esophageal erosions as confirmed by endoscopy. The median age was 15 years, with females accounting for 70% of the patients. During the four week treatment period, the median percentage of 24 hour heartburn free periods was 47%.

8.5 Geriatric Use Of the total number of patients (n=4548) in clinical studies of dexlansoprazole delayed-release capsules, 11% of patients were aged 65 years and over, while 2% were 75 years and over. No overall differences in safety or effectiveness were observed between these patients and younger patients and other reported clinical experience has not identified significant differences in responses between geriatric and younger patients, but greater sensitivity of some older individuals cannot be ruled out [see Clinical Pharmacology (12.3) ] .

8.4 Pediatric Use The safety and effectiveness of dexlansoprazole delayed-release capsules have been established in pediatric patients 12 years to 17 years of age for the healing of all grades of EE, the maintenance of healed EE and relief of heartburn, and treatment of heartburn associated with symptomatic non-erosive GERD. Use of dexlansoprazole delayed-release capsules in this age group is supported by evidence from adequate and well-controlled studies of dexlansoprazole delayed-release capsules in adults with additional safety, efficacy and pharmacokinetic data in pediatric patients 12 to 17 years of age. The adverse reaction profile in patients 12 to 17 years of age was similar to adults [see Dosage and Administration (2.1) , Adverse Reactions (6.1) , Clinical Pharmacology (12.3) , Clinical Studies (14) ] . The safety and effectiveness of dexlansoprazole delayed-release capsules has not been established in pediatric patients less than 12 years of age. Dexlansoprazole delayed-release capsules are not recommended in pediatric patients less than two years of age [see Warnings and Precautions (5.12) ] . Nonclinical studies in juvenile rats treated with lansoprazole (the racemic mixture) have demonstrated adverse effects of heart valve thickening and bone changes at dexlansoprazole exposures which are expected to be similar to or higher than the dexlansoprazole exposure in pediatric patients one year to two years of age, as described below in Juvenile Animal Toxicity Data . The use of dexlansoprazole delayed-release capsules is not recommended for the treatment of symptomatic GERD in pediatric patients one month to less than one year of age because lansoprazole was not shown to be effective in a multicenter, double-blind controlled trial. Juvenile Animal Toxicity Data Heart Valve Thickening In two oral toxicity studies, thickening of the mitral heart valve occurred in juvenile rats treated with lansoprazole. Heart valve thickening was observed primarily with oral dosing initiated on postnatal Day 7 (age equivalent to neonatal humans) and postnatal Day 14 (human age equivalent of approximately one year) at doses of 250 mg/kg/day and higher (at postnatal Day 7 and postnatal Day 14 respectively, 2.5 and 1.8 times the expected dexlansoprazole exposure based on AUC in pediatric patients one year to two years of age). The treatment durations associated with heart valve thickening ranged from 5 days to 8 weeks. The findings reversed or trended towards reversibility after a 4-week drug-free recovery period. The incidence of heart valve thickening after initiation of dosing on postnatal Day 21 (human age equivalent of approximately two years) was limited to a single rat (1/24) in groups given 500 mg/kg/day for 4 or 8 weeks (2.1 times the expected dexlansoprazole exposure based on AUC in pediatric patients one year to two years of age). Based on the low incidence of heart valve thickening in 21-day old rats and the equivalent human age, the risk of heart valve injury does not appear to be relevant to patients two years of age and older. Bone Changes In an eight-week oral toxicity study of lansoprazole in juvenile rats with dosing initiated on postnatal Day 7, doses equal to or greater than 100 mg/kg/day (dexlansoprazole exposure based on AUC approximately equal to that in pediatric patients one year to two years of age) produced delayed growth, with impairment of weight gain observed as early as postnatal Day 10 (age equivalent to neonatal humans). At the end of treatment, the signs of impaired growth at 100 mg/kg/day and higher included reductions in body weight (14 to 44% compared to controls), absolute weight of multiple organs, femur weight, femur length and crown-rump length. Femoral growth plate thickness was reduced only in males and only at the 500 mg/kg/day dose. The effects related to delayed growth persisted through the end of the four-week recovery period. Longer term data were not collected.

8.1 Pregnancy Risk Summary There are no studies with dexlansoprazole use in pregnant women to inform a drug-associated risk. Dexlansoprazole is the R-enantiomer of lansoprazole, and published observational studies of lansoprazole use during pregnancy did not demonstrate an association of adverse pregnancy-related outcomes with lansoprazole (see Data ) . In animal reproduction studies, oral administration of lansoprazole to rats during organogenesis through lactation at 1.8 times the maximum recommended human dexlansoprazole dose produced reductions in the offspring in femur weight, femur length, crown-rump length and growth plate thickness (males only) on postnatal Day 21 (see Data ) . These effects were associated with reduction in body weight gain. Advise pregnant women of the potential risk to the fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the US 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 Human Data Dexlansoprazole is the R-enantiomer of lansoprazole. Available data from published observational studies failed to demonstrate an association of adverse pregnancy-related outcomes and lansoprazole use. Methodological limitations of these observational studies cannot definitely establish or exclude any drug- associated risk during pregnancy. In a prospective study by the European Network of Teratology Information Services, outcomes from a group of 62 pregnant women administered median daily doses of 30 mg of lansoprazole were compared to a control group of 868 pregnant women who did not take any PPIs. There was no difference in the rate of major malformations between women exposed to PPIs and the control group, corresponding to a Relative Risk (RR)=1.04, [95% Confidence Interval (CI) 0.25-4.21]. In a population-based retrospective cohort study covering all live births in Denmark from 1996 to 2008, there was no significant increase in major birth defects during analysis of first trimester exposure to lansoprazole in 794 live births. A meta-analysis that compared 1,530 pregnant women exposed to PPIs in at least the first trimester with 133,410 unexposed pregnant women showed no significant increases in risk for congenital malformations or spontaneous abortion with exposure to PPIs (for major malformations Odds Ratio (OR)=1.12, [95% CI 0.86- 1.45] and for spontaneous abortions OR=1.29, [95% CI 0.84-1.97]). Animal Data An embryo-fetal development study conducted in rabbits at oral dexlansoprazole doses up to 30 mg/kg/day (approximately nine times the maximum recommended human dexlansoprazole dose [60 mg/day] based on body surface area) during organogenesis showed no effects on fetuses due to dexlansoprazole. In addition, embryo-fetal development studies performed in rats with oral lansoprazole at doses up to 150 mg/kg/day (40 times the recommended human lansoprazole dose based on body surface area) during organogenesis and in rabbits with oral lansoprazole at doses up to 30 mg/kg/day (16 times the recommended human lansoprazole dose based on body surface area) during organogenesis revealed no effects on fetuses due to lansoprazole. A pre- and postnatal developmental toxicity study in rats with additional endpoints to evaluate bone development was performed with lansoprazole at oral doses of 10 to 100 mg/kg/day (0.2 to 1.8 times the maximum recommended human dexlansoprazole dose of 60 mg based on dexlansoprazole AUC [area under the plasma concentration-time curve]) administered during organogenesis through lactation. Maternal effects observed at 100 mg/kg/day (1.8 times the maximum recommended human dexlansoprazole dose of 60 mg based on dexlansoprazole AUC) included increased gestation period, decreased body weight gain during gestation, and decreased food consumption. The number of stillbirths was increased at this dose, which may have been secondary to maternal toxicity. Body weight of pups was reduced at 100 mg/kg/day starting on postnatal Day 11. Femur weight, femur length, and crown-rump length were reduced at 100 mg/kg/day on postnatal Day 21. Femur weight was still decreased in the 100 mg/kg/day group at age 17 to 18 weeks. Growth plate thickness was decreased in the 100 mg/kg/day males on postnatal Day 21, and was increased in the 30 and 100 mg/kg/day males at age 17 to 18 weeks. The effects on bone parameters were associated with reduction in body weight gain.

8 USE IN SPECIFIC POPULATIONS Pregnancy : Based on animal data, may cause adverse effects on fetal bone growth and development. ( 8.1 ) Pediatrics : Based on data with lansoprazole, dexlansoprazole delayed-release capsules are not effective in patients with symptomatic GERD 1 month to less than 1 year of age and nonclinical studies have demonstrated adverse effects in juvenile rats.

The effects on bone parameters were associated with reduction in body weight gain. 8.2 Lactation Risk Summary There is no information regarding the presence of dexlansoprazole in human milk, the effects on the breastfed infant, or the effects on milk production. However, lansoprazole and its metabolites are present in rat milk . The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for dexlansoprazole delayed-release capsules and any potential adverse effects on the breastfed child from dexlansoprazole delayed-release capsules or from the underlying maternal condition. 8.4 Pediatric Use The safety and effectiveness of dexlansoprazole delayed-release capsules have been established in pediatric patients 12 years to 17 years of age for the healing of all grades of EE, the maintenance of healed EE and relief of heartburn, and treatment of heartburn associated with symptomatic non-erosive GERD. Use of dexlansoprazole delayed-release capsules in this age group is supported by evidence from adequate and well-controlled studies of dexlansoprazole delayed-release capsules in adults with additional safety, efficacy and pharmacokinetic data in pediatric patients 12 to 17 years of age. The adverse reaction profile in patients 12 to 17 years of age was similar to adults [see Dosage and Administration (2.1) , Adverse Reactions (6.1) , Clinical Pharmacology (12.3) , Clinical Studies (14) ] . The safety and effectiveness of dexlansoprazole delayed-release capsules has not been established in pediatric patients less than 12 years of age. Dexlansoprazole delayed-release capsules are not recommended in pediatric patients less than two years of age [see Warnings and Precautions (5.12) ] . Nonclinical studies in juvenile rats treated with lansoprazole (the racemic mixture) have demonstrated adverse effects of heart valve thickening and bone changes at dexlansoprazole exposures which are expected to be similar to or higher than the dexlansoprazole exposure in pediatric patients one year to two years of age, as described below in Juvenile Animal Toxicity Data . The use of dexlansoprazole delayed-release capsules is not recommended for the treatment of symptomatic GERD in pediatric patients one month to less than one year of age because lansoprazole was not shown to be effective in a multicenter, double-blind controlled trial. Juvenile Animal Toxicity Data Heart Valve Thickening In two oral toxicity studies, thickening of the mitral heart valve occurred in juvenile rats treated with lansoprazole. Heart valve thickening was observed primarily with oral dosing initiated on postnatal Day 7 (age equivalent to neonatal humans) and postnatal Day 14 (human age equivalent of approximately one year) at doses of 250 mg/kg/day and higher (at postnatal Day 7 and postnatal Day 14 respectively, 2.5 and 1.8 times the expected dexlansoprazole exposure based on AUC in pediatric patients one year to two years of age). The treatment durations associated with heart valve thickening ranged from 5 days to 8 weeks. The findings reversed or trended towards reversibility after a 4-week drug-free recovery period. The incidence of heart valve thickening after initiation of dosing on postnatal Day 21 (human age equivalent of approximately two years) was limited to a single rat (1/24) in groups given 500 mg/kg/day for 4 or 8 weeks (2.1 times the expected dexlansoprazole exposure based on AUC in pediatric patients one year to two years of age). Based on the low incidence of heart valve thickening in 21-day old rats and the equivalent human age, the risk of heart valve injury does not appear to be relevant to patients two years of age and older. Bone Changes In an eight-week oral toxicity study of lansoprazole in juvenile rats with dosing initiated on postnatal Day 7, doses equal to or greater than 100 mg/kg/day (dexlansoprazole exposure based on AUC approximately equal to that in pediatric patients one year to two years of age) produced delayed growth, with impairment of weight gain observed as early as postnatal Day 10 (age equivalent to neonatal humans). At the end of treatment, the signs of impaired growth at 100 mg/kg/day and higher included reductions in body weight (14 to 44% compared to controls), absolute weight of multiple organs, femur weight, femur length and crown-rump length. Femoral growth plate thickness was reduced only in males and only at the 500 mg/kg/day dose. The effects related to delayed growth persisted through the end of the four-week recovery period. Longer term data were not collected. 8.5 Geriatric Use Of the total number of patients (n=4548) in clinical studies of dexlansoprazole delayed-release capsules, 11% of patients were aged 65 years and over, while 2% were 75 years and over. No overall differences in safety or effectiveness were observed between these patients and younger patients and other reported clinical experience has not identified significant differences in responses between geriatric and younger patients, but greater sensitivity of some older individuals cannot be ruled out [see Clinical Pharmacology (12.3) ] . 8.6 Hepatic Impairment No dosage adjustment for dexlansoprazole delayed-release capsules is necessary for patients with mild hepatic impairment (Child-Pugh Class A). In a study of adult patients with moderate hepatic impairment (Child-Pugh Class B) who received a single dose of 60 mg dexlansoprazole delayed-release capsules, there was a significant increase in systemic exposure of dexlansoprazole compared to healthy subjects with normal hepatic function [see Clinical Pharmacology (12.3) ] . Therefore, for patients with moderate hepatic impairment (Child-Pugh Class B), dosage reduction is recommended for the healing of EE [see Dosage and Administration (2.2) ]. No studies have been conducted in patients with severe hepatic impairment (Child-Pugh Class C); the use of dexlansoprazole delayed-release capsules is not recommended for these patients [see Dosage and Administration (2.2) ] .
