4 CONTRAINDICATIONS

5 WARNINGS AND PRECAUTIONS

5.1 Presence of Gastric Malignancy

In adults, symptomatic response to therapy with Dexilant does not preclude the presence of gastric malignancy. Consider additional follow-up and diagnostic testing in adult patients who have a suboptimal response or an early symptomatic relapse after completing treatment with a PPI. In older patients, also consider an endoscopy.

5.2 Acute Interstitial Nephritis

Acute interstitial nephritis has been observed in patients taking PPIs including lansoprazole. Acute interstitial nephritis may occur at any point during PPI therapy and is generally attributed to an idiopathic hypersensitivity reaction. Discontinue Dexilant if acute interstitial nephritis develops .

5.3 Clostridium difficile-Associated Diarrhea

Published observational studies suggest that PPI therapy like Dexilant may be associated with an increased risk of Clostridium difficile-associated diarrhea, especially in hospitalized patients. This diagnosis should be considered for diarrhea that does not improve .

Patients should use the lowest dose and shortest duration of PPI therapy appropriate to the condition being treated.

5.4 Bone Fracture

Several published observational studies suggest that PPI therapy may be associated with an increased risk for osteoporosis-related fractures of the hip, wrist or spine. The risk of fracture was increased in patients who received high-dose, defined as multiple daily doses, and long-term PPI therapy. Patients should use the lowest dose and shortest duration of PPI therapy appropriate to the conditions being treated. Patients at risk for osteoporosis-related fractures should be managed according to established treatment guidelines .

5.5 Cutaneous and Systemic Lupus Erythematosus

Cutaneous lupus erythematosus (CLE) and systemic lupus erythematosus (SLE) have been reported in patients taking PPIs. These events have occurred as both new onset and an exacerbation of existing autoimmune disease. The majority of PPI-induced lupus erythematosus cases were CLE.

The most common form of CLE reported in patients treated with PPIs was subacute CLE (SCLE) and occurred within weeks to years after continuous drug therapy in patients ranging from infants to the elderly. Generally, histological findings were observed without organ involvement.

Systemic lupus erythematosus (SLE) is less commonly reported than CLE in patients receiving PPIs. PPI-associated SLE is usually milder than non-drug induced SLE. Onset of SLE typically occurred within days to years after initiating treatment primarily in patients ranging from young adults to the elderly. The majority of patients presented with rash; however, arthralgia and cytopenia were also reported.

Avoid administration of PPIs for longer than medically indicated. If signs or symptoms consistent with CLE or SLE are noted in patients receiving Dexilant, discontinue the drug and refer the patient to the appropriate specialist for evaluation. Most patients improve with discontinuation of the PPI alone in four to 12 weeks. Serological testing (e.g., ANA) may be positive and elevated serological test results may take longer to resolve than clinical manifestations.

5.6 Cyanocobalamin Deficiency

Daily treatment with any acid-suppressing medications over a long period of time (e.g., longer than three years) may lead to malabsorption of cyanocobalamin (Vitamin B12) caused by hypo- or achlorhydria. Rare reports of cyanocobalamin deficiency occurring with acid-suppressing therapy have been reported in the literature. This diagnosis should be considered if clinical symptoms consistent with cyanocobalamin deficiency are observed in patients treated with Dexilant.

5.7 Hypomagnesemia

Hypomagnesemia, symptomatic and asymptomatic, has been reported rarely in patients treated with PPIs for at least three months, in most cases after a year of therapy. Serious adverse events include tetany, arrhythmias, and seizures. In most patients, treatment of hypomagnesemia required magnesium replacement and discontinuation of the PPI.

For patients expected to be on prolonged treatment or who take PPIs with medications such as digoxin or drugs that may cause hypomagnesemia, healthcare professionals may consider monitoring magnesium levels prior to initiation of PPI treatment and periodically .

5.8 Interactions with Investigations for Neuroendocrine Tumors

Serum chromogranin A (CgA) levels increase secondary to drug-induced decreases in gastric acidity. The increased CgA level may cause false positive results in diagnostic investigations for neuroendocrine tumors. Healthcare providers should temporarily stop Dexilant 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 .

5.9 Interaction with Methotrexate

Literature suggests that concomitant use of PPIs with methotrexate (primarily at high dose) may elevate and prolong serum levels of methotrexate and/or its metabolite, possibly leading to methotrexate toxicities. In high-dose methotrexate administration, a temporary withdrawal of the PPI may be considered in some patients .

7 DRUG INTERACTIONS

Tables 3 and 4 include drugs with clinically important drug interactions and interaction with diagnostics when administered concomitantly with Dexilant and instructions for preventing or managing them.

Consult the labeling of concomitantly used drugs to obtain further information about interactions with PPIs.

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 Dexilant may reduce antiviral effect and promote the development of drug resistance.
  • Increased exposure of other antiretroviral drugs (e.g., saquinavir) when used concomitantly with Dexilant may increase toxicity of the antiretroviral drugs.
  • There are other antiretroviral drugs which do not result in clinically relevant interactions with Dexilant.
Intervention: Rilpivirine-containing products: Concomitant use with Dexilant is contraindicated . See prescribing information.

Atazanavir: See prescribing information for atazanavir for dosing information.

Nelfinavir: Avoid concomitant use with Dexilant. 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 .
Intervention: A temporary withdrawal of Dexilant 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: Dexilant can reduce the absorption of other drugs due to its effect on reducing intragastric acidity.
Intervention: Mycophenolate mofetil (MMF): Co-administration 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 Dexilant and MMF. Use Dexilant 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.
Intervention: Temporarily stop Dexilant 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 Dexilant treatment at least 30 days before assessing to allow gastrin levels to return to baseline .
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.
CYP2C19 or CYP3A4 Inducers
Clinical Impact: Decreased exposure of Dexilant when used concomitantly with strong inducers .
Intervention: St. John's Wort, rifampin: Avoid concomitant use with Dexilant.

Ritonavir-containing products: See prescribing information.

CYP2C19 or CYP3A4 Inhibitors
Clinical Impact: Increased exposure of Dexilant is expected when used concomitantly with strong inhibitors .
Intervention: Voriconazole: See prescribing information.

See full prescribing information for a list of clinically important drug interactions. (7)

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Risk Summary

There are no studies with Dexilant use in pregnant women to inform a drug-associated risk. In animal reproduction studies, no effects on embryo-fetal development were observed with the administration of oral Dexilant to rabbits during organogenesis at doses up to nine times the maximum recommended human dose (based on body surface area) or with administration of oral lansoprazole to rats and rabbits during organogenesis at doses up to 40 and 16 times the MRHD (based on body surface area), respectively .

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. 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

An embryo-fetal development study conducted in rabbits at oral Dexilant doses up to 30 mg/kg/day (approximately nine times the maximum recommended human Dexilant dose [60 mg/day] based on body surface area) during organogenesis showed no effects on fetuses due to Dexilant. 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.

8.2 Lactation

Risk Summary

There is no information regarding the presence of Dexilant 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 Dexilant and any potential adverse effects on the breastfed child from Dexilant or from the underlying maternal condition.

Data

When [14C] lansoprazole was administered orally at 2 mg/kg to lactating rats 14 days after parturition, milk collected at 0.5, 2 and 6 hours after the lansoprazole dose contained 2 to 6 fold higher concentrations of radioactivity than plasma. Almost all of the radioactivity was determined to be from lansoprazole metabolites.

8.4 Pediatric Use

The safety and effectiveness of Dexilant capsules have been established in pediatric patients 12 to 17 years of age for the healing of all grades of EE. The safety and effectiveness of Dexilant capsules have been established in pediatric patients 12 to 17 years of age for the maintenance of healed EE and relief of heartburn, and treatment of heartburn associated with symptomatic non-erosive GERD.

Use of Dexilant in this age group is supported by evidence from adequate and well-controlled studies of Dexilant 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.

The safety and effectiveness of Dexilant have not been established in pediatric patients less than 12 years of age.

The use of Dexilant is not recommended for symptomatic non-erosive GERD in pediatric patients less than one year of age because studies in this class of drugs have not demonstrated efficacy.

8.5 Geriatric Use

Of the total number of patients (n=4548) in clinical studies of Dexilant, 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 .

8.6 Hepatic Impairment

No dosage adjustment for Dexilant 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 60 mg Dexilant capsule, there was a significant increase in systemic exposure of Dexilant compared to healthy subjects with normal hepatic function . Therefore, for patients with moderate hepatic impairment (Child-Pugh Class B), dosage reduction is recommended for the healing of EE .

No studies have been conducted in patients with severe hepatic impairment (Child-Pugh Class C); the use of Dexilant capsules is not recommended for these patients .

10 OVERDOSAGE

There have been no reports of significant overdose with Dexilant. Multiple doses of Dexilant 120 mg and a single dose of Dexilant 300 mg did not result in death or other severe adverse events. However, serious adverse events of hypertension have been reported in association with twice daily doses of Dexilant 60 mg. Non-serious adverse reactions observed with twice daily doses of Dexilant 60 mg include hot flashes, contusion, oropharyngeal pain, and weight loss. Dexilant 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.

11 DESCRIPTION

The active ingredient in Dexilant (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. Dexilant is the R-enantiomer of lansoprazole (a racemic mixture of the R- and S-enantiomers). Its empirical formula is: C16H14F3N3O2S, with a molecular weight of 369.36. Dexilant has the following chemical structure:

Dexilant is a white to nearly white crystalline powder which melts with decomposition at 140°C. Dexilant 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.

Dexilant is stable when exposed to light. Dexilant is more stable in neutral and alkaline conditions than acidic conditions.

Dexilant is supplied for oral administration as a dual delayed-release formulation in capsules. The capsules contain Dexilant in a mixture of two types of enteric-coated granules with different pH-dependent dissolution profiles .

Dexilant delayed-release capsules are available in two dosage strengths: 30 and 60 mg, per capsule. Each capsule contains enteric-coated granules consisting of Dexilant (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 aluminum lake; gray contains black ferric oxide; and both contain titanium dioxide.

Chemical Structure

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Dexilant belongs to a class of antisecretory compounds, the substituted benzimidazoles, that suppress gastric acid secretion by specific inhibition of the -ATPase at the secretory surface of the gastric parietal cell. Because this enzyme is regarded as the acid (proton) pump within the parietal cell, Dexilant 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 Dexilant 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.

Serum Gastrin Effects

The effect of Dexilant 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 Dexilant 30 and 60 mg 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 pre-treatment 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 .

Enterochromaffin-Like Cell (ECL) Effects

There were no reports of ECL cell hyperplasia in gastric biopsy specimens obtained from 653 patients treated with Dexilant 30, 60, or 90 mg capsules 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 .

Cardiac Electrophysiology

At a dose five times the maximum recommended dose, Dexilant does not prolong the QT interval to any clinically relevant extent.

12.3 Pharmacokinetics

The dual delayed-release formulation of Dexilant capsules results in a Dexilant 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. Dexilant is eliminated with a half-life of approximately one to two hours in healthy subjects and in patients with symptomatic GERD. No accumulation of Dexilant occurs after multiple, once daily doses of Dexilant 30 or 60 mg capsules although mean AUCt and Cmax values of Dexilant were slightly higher (less than 10%) on Day 5 than on Day 1.

Absorption

After oral administration of Dexilant 30 or 60 mg capsules to healthy subjects and symptomatic GERD patients, mean Cmax and AUC values of Dexilant increased approximately dose proportionally (see Figure 1 ).

When granules of Dexilant 60 mg capsules are mixed with water and dosed via NG tube or orally via syringe, the bioavailability (Cmax and AUC) of Dexilant was similar to that when Dexilant 60 mg was administered as an intact capsule .

Effect on Food

In food-effect studies in healthy subjects receiving Dexilant capsules under various fed conditions compared to fasting, increases in Cmax ranged from 12 to 55%, increases in AUC ranged from 9 to 37%, and Tmax varied (ranging from a decrease of 0.7 hours to an increase of three hours).

Distribution

Plasma protein binding of Dexilant 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 (Vz/F) after multiple doses in symptomatic GERD patients was 40 L.

Elimination

Metabolism

Dexilant 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). Dexilant 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 Dexilant and its glucuronide conjugate, while in CYP2C19 poor metabolizers Dexilant sulfone is the major plasma metabolite.

Excretion

Following the administration of Dexilant capsules, no unchanged Dexilant is excreted in urine. Following the administration of [14C] Dexilant 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 Dexilant in patients under the age of 12 years have not been studied.

Patients 12 to 17 Years of Age

The pharmacokinetics of Dexilant were studied in 36 patients 12 to 17 years of age with symptomatic GERD in a multi-center trial. Patients were randomized to receive Dexilant 30 or 60 mg capsules once daily for seven days. The Dexilant mean Cmax 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 .

Age: Geriatric Population

The terminal elimination half-life of Dexilant is significantly increased in geriatric subjects compared to younger subjects (2.2 and 1.5 hours, respectively). Dexilant exhibited higher systemic exposure (AUC) in geriatric subjects (34% higher) than younger subjects .

Sex

In a study of 12 male and 12 female healthy subjects who received a single oral dose of Dexilant 60 mg capsules, females had higher systemic exposure (AUC) (43% higher) than males. This difference in exposure between males and female does not represent a significant safety concern.

Renal Impairment

Dexilant is extensively metabolized in the liver to inactive metabolites, and no parent drug is recovered in the urine following an oral dose of Dexilant. Therefore, the pharmacokinetics of Dexilant 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 oral dose of 60 mg Dexilant capsules, the systemic exposure (AUC) of bound and unbound Dexilant 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) .

Drug-Drug Interactions

Effect of Dexilant on Other Drugs

Cytochrome P 450 Interactions

Dexilant is metabolized, in part, by CYP2C19 and CYP3A4 .

In vitro studies have shown that Dexilant 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 Dexilant 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 Dexilant 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 Dexilant 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 Dexilant 60 mg capsules (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 Dexilant was 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 Dexilant

Because Dexilant is metabolized by CYP2C19 and CYP3A4, inducers and inhibitors of these enzymes may potentially alter exposure of Dexilant.

Figure 1

12.5 Pharmacogenomics

Effect of CYP2C19 Polymorphism on Systemic Exposure of Dexilant

Systemic exposure of Dexilant is generally higher in intermediate and poor metabolizers. In male Japanese subjects who received a single dose of Dexilant 30 or 60 mg capsules (N=2 to 6 subjects/group), mean Dexilant Cmax and AUC values were up to two times higher in intermediate compared to extensive metabolizers; in poor metabolizers, mean Cmax 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 Dexilant exposure in these races will be affected by CYP2C19 phenotypes as well.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

The carcinogenic potential of Dexilant 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/m2) basis of a 50 kg person of average height [1.46 m2 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 .

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.

Dexilant was positive in the Ames test and in the in vitro chromosome aberration test using Chinese hamster lung cells. Dexilant was negative in the in vivo mouse micronucleus test.

The potential effects of Dexilant 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.

14 CLINICAL STUDIES

14.1 Healing of Erosive Esophagitis in Adults

Two multi-center, 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. Patients were randomized to one of the following three treatment groups: Dexilant 60 mg capsules daily, Dexilant 90 mg capsules daily or lansoprazole 30 mg 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 non-inferiority. If non-inferiority was demonstrated then superiority would be tested. Although non-inferiority 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.

14.2 Maintenance of Healed Erosive Esophagitis and Relief of Heartburn in Adults

A multi-center, double-blind, placebo-controlled, randomized study was conducted in patients who successfully completed an EE study and showed endoscopically confirmed healed EE. Maintenance of healing and symptom resolution over a six month period were evaluated with Dexilant 30 or 60 mg capsules 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 Dexilant capsules remained healed over the six month time period as confirmed by endoscopy .

14.3 Treatment of Symptomatic Non-Erosive GERD in Adults

A multi-center, double-blind, placebo-controlled, randomized, four week study was conducted in patients with a diagnosis of symptomatic non-erosive GERD made primarily by presentation of symptoms. 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: Dexilant 30 mg daily, 60 mg daily, or placebo. A total of 947 patients were enrolled and ranged in age from 18 to 86 years with 71% female. Race was distributed as follows: 82% Caucasian, 14% Black and 4% other.

Dexilant 30 mg capsules provided statistically significantly greater percent of days with heartburn-free 24 hour periods over placebo as assessed by daily diary over four weeks . Dexilant 60 mg capsules was studied and provided no additional clinical benefit over Dexilant 30 mg capsules.

14.4 Pediatric GERD

Use of Dexilant in patients 12 to 17 years of age is supported by evidence from adequate and well-controlled studies of Dexilant capsules in adults, with additional safety, efficacy, and pharmacokinetic data from studies performed in pediatric patients.

Healing of EE, Maintenance of Healed EE and Relief of Heartburn

In a multi-center, 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 Dexilant 60 mg capsules 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 .

After the initial eight weeks of treatment, all 51 patients with healed EE were randomized to receive treatment with Dexilant 30 mg capsules 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 post-baseline endoscopy. Eighteen of 22 (82%) evaluable patients treated with Dexilant 30 mg capsules remained healed over the 16 week treatment period as confirmed by endoscopy, compared with 14 of 24 (58%) in placebo .

Relief of heartburn was assessed in randomized patients during the 16 week maintenance period. The median percentage of 24 hour heartburn-free periods was 87% for those receiving Dexilant 30 mg capsules 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 Dexilant 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, multi-center trial, 104 pediatric patients 12 to 17 years of age with symptomatic non-erosive GERD were treated with Dexilant 30 mg capsules 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%.

MEDICATION GUIDE

Dexilant (decks-i-launt)

(dexlansoprazole)

delayed-release capsules

Read this Medication Guide before you start taking Dexilant 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 Dexilant?

Dexilant may help your acid-related symptoms, but you could still have serious stomach problems. Talk with your doctor.

Dexilant can cause serious side effects, including:

  • A type of kidney problem (acute interstitial nephritis). Some people who take proton pump inhibitor (PPI) medicines, including Dexilant, may develop a kidney problem called acute interstitial 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. Dexilant 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 Dexilant 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 Dexilant.
  • 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.

Dexilant can have other serious side effects. See "What are the possible side effects of Dexilant?"

What is Dexilant?

Dexilant is a prescription medicine called a proton pump inhibitor (PPI). Dexilant reduces the amount of acid in your stomach.

Dexilant 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 Dexilant is safe and effective in children under 12 years of age.

Dexilant is not effective for symptoms of GERD in children under 1 year of age.

Who should not take Dexilant?

Do not take Dexilant if you:

  • are allergic to Dexilant or any of the other ingredients in Dexilant. See the end of this Medication Guide for a complete list of ingredients in Dexilant.
  • are taking a medicine that contains rilpivirine (EDURANT, COMPLERA) used to treat HIV-1 (Human Immunodeficiency Virus)
What should I tell my doctor before taking Dexilant?

Before you take Dexilant, tell your doctor if you:

  • have been told that you have low magnesium levels in your blood
  • have liver problems
  • have any other medical conditions
  • are pregnant or plan to become pregnant. It is not known if Dexilant will harm your unborn baby.
  • are breastfeeding or plan to breastfeed. It is not known if Dexilant passes into your breast milk or if it will affect your baby or your breast milk. Talk to your doctor about the best way to feed your baby if you take Dexilant.

Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Dexilant may affect how other medicines work, and other medicines may affect how Dexilant works. Especially tell your doctor if you take methotrexate (Otrexup, Rasuvo, Trexall).

Know the medicines that you take. Keep a list of them to show your doctor and pharmacist when you get a new medicine.

How should I take Dexilant?
  • Take Dexilant exactly as prescribed by your doctor.
  • Do not change your dose or stop taking Dexilant without talking to your doctor first.

    Dexilant capsules:

    • Take Dexilant capsules with or without food.
    • Swallow Dexilant capsules whole. Do not chew Dexilant capsules or the granules that are in the capsules.
    • If you have trouble swallowing a whole capsule, you can open the capsule and take the contents in applesauce. See the "Instructions for Use" at the end of this Medication Guide for instructions on how to take Dexilant capsules with applesauce.
    • See the "Instructions for Use" at the end of this Medication Guide for instructions on how to mix and give Dexilant capsules with water using an oral syringe or through a nasogastric tube.
  • If you miss a dose of Dexilant, take it as soon as you remember. If it is almost time for your next dose, do not take the missed dose. Take your next dose at your regular time. Do not take 2 doses at the same time to make up for the missed dose.
  • If you take too much Dexilant, call your doctor or your poison control center at 1-800-222-1222 right away or go to the nearest hospital emergency room.
What are the possible side effects of Dexilant?

Dexilant may cause serious side effects, including:

  • See "What is the most important information I should know about Dexilant?"
  • Vitamin B12 deficiency. Dexilant reduces the amount of acid in your stomach. Stomach acid is needed to absorb Vitamin B12 properly. Talk with your doctor about the possibility of Vitamin B12 deficiency if you have been on Dexilant for a long time (more than 3 years).
  • Low magnesium levels in your body. This problem can be serious. Low magnesium can happen in some people who take a PPI medicine for at least 3 months. If low magnesium levels happen, it is usually after a year of treatment. You may or may not have symptoms of low magnesium.

    Tell your doctor right away if you develop any of these symptoms:

    • seizures
    • dizziness
    • abnormal or fast heartbeat
    • jitteriness
    • jerking movements or shaking (tremors)
    • muscle weakness
    • spasms of the hands and feet
    • cramps or muscle aches
    • spasm of the voice box

    Your doctor may check the level of magnesium in your body before you start taking Dexilant, or during treatment, if you will be taking Dexilant for a long period of time.


The most common side effects of Dexilant in adults include:

  • diarrhea
  • stomach pain
  • nausea
  • common cold
  • vomiting
  • gas

The most common side effects of Dexilant in children 12 to 17 years of age include:

Dexilant pharmaceutical active ingredients containing related brand and generic drugs:

Active ingredient is the part of the drug or medicine which is biologically active. This portion of the drug is responsible for the main action of the drug which is intended to cure or reduce the symptom or disease. The other portions of the drug which are inactive are called excipients; there role is to act as vehicle or binder. In contrast to active ingredient, the inactive ingredient's role is not significant in the cure or treatment of the disease. There can be one or more active ingredients in a drug.


Dexilant available forms, composition, doses:

Form of the medicine is the form in which the medicine is marketed in the market, for example, a medicine X can be in the form of capsule or the form of chewable tablet or the form of tablet. Sometimes same medicine can be available as injection form. Each medicine cannot be in all forms but can be marketed in 1, 2, or 3 forms which the pharmaceutical company decided based on various background research results.
Composition is the list of ingredients which combinedly form a medicine. Both active ingredients and inactive ingredients form the composition. The active ingredient gives the desired therapeutic effect whereas the inactive ingredient helps in making the medicine stable.
Doses are various strengths of the medicine like 10mg, 20mg, 30mg and so on. Each medicine comes in various doses which is decided by the manufacturer, that is, pharmaceutical company. The dose is decided on the severity of the symptom or disease.


Dexilant destination | category:

Destination is defined as the organism to which the drug or medicine is targeted. For most of the drugs what we discuss, human is the drug destination.
Drug category can be defined as major classification of the drug. For example, an antihistaminic or an antipyretic or anti anginal or pain killer, anti-inflammatory or so.


Dexilant Anatomical Therapeutic Chemical codes:

A medicine is classified depending on the organ or system it acts [Anatomical], based on what result it gives on what disease, symptom [Therapeutical], based on chemical composition [Chemical]. It is called as ATC code. The code is based on Active ingredients of the medicine. A medicine can have different codes as sometimes it acts on different organs for different indications. Same way, different brands with same active ingredients and same indications can have same ATC code.


Dexilant pharmaceutical companies:

Pharmaceutical companies are drug manufacturing companies that help in complete development of the drug from the background research to formation, clinical trials, release of the drug into the market and marketing of the drug.
Researchers are the persons who are responsible for the scientific research and is responsible for all the background clinical trials that resulted in the development of the drug.
