No adjustment for KAPIDEX is necessary for patients with mild hepatic impairment (Child-Pugh Class A). Consider a maximum daily dose of 30 mg for patients with moderate hepatic impairment (Child-Pugh Class B). No studies have been conducted in patients with severe hepatic impairment (Child-Pugh Class C) [see Use in Specific Populations (8.7) and Clinical Pharmacology (12.5)].

No dosage adjustment is necessary for elderly patients or for patients with renal impairment [see Clinical Pharmacology (12.5)].

3 DOSAGE FORMS AND STRENGTHS

• 30 mg capsules are opaque, blue and gray with TAP and "30" imprinted on the capsule.
• 60 mg capsules are opaque, blue with TAP and "60" imprinted on the capsule.

4 CONTRAINDICATIONS

KAPIDEX is contraindicated in patients with known hypersensitivity to any component of the formulation [see Description (11)]. Hypersensitivity and anaphylaxis have been reported with KAPIDEX use [see Adverse Reactions (6.1)].

5 WARNINGS AND PRECAUTIONS

Symptomatic response with KAPIDEX does not preclude the presence of gastric malignancy.

6 ADVERSE REACTIONS

The safety of KAPIDEX was evaluated in 4548 patients in controlled and uncontrolled clinical studies, including 863 patients treated for at least 6 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 KAPIDEX 30 mg, 2218 patients on KAPIDEX 60 mg, and 1363 patients on lansoprazole 30 mg once daily.

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

Other adverse reactions not observed with KAPIDEX, but occurring with the racemate lansoprazole can be found in the lansoprazole package insert, ADVERSE REACTIONS section.

7 DRUG INTERACTIONS

KAPIDEX causes inhibition of gastric acid secretion. KAPIDEX is likely to substantially decrease the systemic concentrations of the HIV protease inhibitor atazanavir, which is dependent upon the presence of gastric acid for absorption, and may result in a loss of therapeutic effect of atazanavir and the development of HIV resistance. Therefore, KAPIDEX should not be co-administered with atazanavir.

It is theoretically possible that KAPIDEX may interfere with the absorption of other drugs where gastric pH is an important determinant of oral bioavailability (e.g., ampicillin esters, digoxin, iron salts, ketoconazole).

Co-administration of KAPIDEX 90 mg and warfarin 25 mg did not affect the pharmacokinetics of warfarin or INR [see Clinical Pharmacology (12.6)]. However, there have been reports of 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. Patients treated with KAPIDEX and warfarin concomitantly may need to be monitored for increases in INR and prothrombin time.

8 USE IN SPECIFIC POPULATIONS

Teratogenic Effects

Pregnancy Category B. There are no adequate and well-controlled studies with dexlansoprazole in pregnant women. There were no adverse fetal effects in animal reproduction studies of dexlansoprazole in rabbits. Because animal reproduction studies are not always predictive of human response, KAPIDEX should be used during pregnancy only if clearly needed.

A reproduction study conducted in rabbits at oral dexlansoprazole doses up to 30 mg per kg per day (approximately 9-fold the maximum recommended human dexlansoprazole dose [60 mg] based on body surface area [BSA]) revealed no evidence of harm to the fetus due to dexlansoprazole. In addition, reproduction studies performed in pregnant rats with oral lansoprazole at doses up to 150 mg per kg per day (40 times the recommended human dose based on BSA) and in pregnant rabbits at oral lansoprazole doses up to 30 mg per kg per day (16 times the recommended human dose based on BSA) revealed no evidence of impaired fertility or harm to the fetus due to lansoprazole.

It is not known whether dexlansoprazole is excreted in human milk. However, lansoprazole and its metabolites are present in rat milk following the administration of lansoprazole. As many drugs are excreted in human milk, and because of the potential for tumorigenicity shown for lansoprazole in rat carcinogenicity studies [see Carcinogenesis, Mutagenesis, Impairment of Fertility (13.1)], a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Safety and effectiveness of KAPIDEX in pediatric patients (less than 18 years of age) have not been established.

In clinical studies of KAPIDEX, 11% of patients were aged 65 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 (12.5)].

No dosage adjustment of KAPIDEX is necessary in patients with renal impairment. The pharmacokinetics of dexlansoprazole in patients with renal impairment are not expected to be altered since 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 [see Clinical Pharmacology (12.5)].

No dosage adjustment for KAPIDEX is necessary for patients with mild hepatic impairment (Child-Pugh Class A). KAPIDEX 30 mg should be considered for patients with moderate hepatic impairment (Child-Pugh Class B). No studies have been conducted in patients with severe hepatic impairment (Child-Pugh Class C) [see Clinical Pharmacology (12.5)].

10 OVERDOSAGE

There have been no reports of significant overdose of KAPIDEX. Multiple doses of KAPIDEX 120 mg and a single dose of KAPIDEX 300 mg did not result in death or other severe adverse events. Dexlansoprazole is not expected to be removed from the circulation by hemodialysis. If an overdose occurs, treatment should be symptomatic and supportive.

11 DESCRIPTION

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.

KAPIDEX is supplied as a dual delayed release formulation in capsules for oral administration. 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)].

KAPIDEX is available in two dosage strengths: 30 mg 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 copolymer, 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 and aluminum lake; gray contains ferric oxide and aluminum lake; and both contain titanium dioxide.

12 CLINICAL PHARMACOLOGY

During lifetime exposure of rats dosed daily with up to 150 mg per kg per 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)].

The dual delayed release formulation of KAPIDEX results in a dexlansoprazole plasma concentration-time profile with two distinct peaks; the first peak occurs 1 to 2 hours after administration, followed by a second peak within 4 to 5 hours (see Figure 1). Dexlansoprazole is eliminated with a half-life of approximately 1 to 2 hours in healthy subjects and in patients with symptomatic GERD. No accumulation of dexlansoprazole occurs after multiple, once daily doses of KAPIDEX 30 mg 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 KAPIDEX
Once Daily for 5 Days in Healthy 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 4).

Absorption

After oral administration of KAPIDEX 30 mg 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).

Distribution

Plasma protein binding of dexlansoprazole ranged from 96.1% to 98.8% in healthy subjects and was independent of concentration from 0.01 to 20 mcg per mL. The apparent volume of distribution (V_z/F) after multiple doses in symptomatic GERD patients was 40.3 L.

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.

Elimination

Following the administration of KAPIDEX, no unchanged dexlansoprazole is excreted in urine. Following the administration of [¹⁴C]dexlansoprazole to 6 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/h, respectively, after 5-days of 30 or 60 mg once daily administration.

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 KAPIDEX 30 mg or 60 mg (N=2 to 6 subjects/group), mean dexlansoprazole C_max and AUC values were up to 2 times higher in intermediate compared to extensive metabolizers; in poor metabolizers, mean C_max was up to 4 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.

In food-effect studies in healthy subjects receiving KAPIDEX 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 3 hours). No significant differences in mean intragastric pH were observed between fasted and various fed conditions. However, the percentage of time intragastric pH exceeded 4 over the 24-hour dosing interval decreased slightly when KAPIDEX was administered after a meal (57%) relative to fasting (64%), primarily due to a decreased response in intragastric pH during the first 4 hours after dosing. Because of this, while KAPIDEX can be taken without regard to food, some patients may benefit from administering the dose prior to a meal if post-meal symptoms do not resolve under post-fed conditions.

Pediatric Use

The pharmacokinetics of dexlansoprazole in patients under the age of 18 years have not been studied.

Geriatric Use

The terminal elimination half-life of dexlansoprazole is significantly increased in geriatric subjects compared to younger subjects (2.23 and 1.5 hours, respectively); this difference is not clinically relevant. Dexlansoprazole exhibited higher systemic exposure (AUC) in geriatric subjects (34.5% higher) than younger subjects. No dosage adjustment is needed in geriatric patients [see Use in Specific Populations (8.5)].

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 subjects with renal impairment [see Use in Specific Populations (8.6)]. In addition, the pharmacokinetics of lansoprazole were studied in patients with mild, moderate or severe renal impairment; results demonstrated no need for a dose adjustment for this patient population.

Hepatic Impairment

In a study of 12 patients with moderately impaired hepatic function who received a single oral dose of KAPIDEX 60 mg, plasma exposure (AUC) of bound and unbound dexlansoprazole in the hepatic impairment group was approximately 2 times greater compared to subjects with normal hepatic function. This difference in exposure was not due to a difference in protein binding between the two liver function groups. No adjustment for KAPIDEX is necessary for patients with mild hepatic impairment (Child-Pugh Class A). KAPIDEX 30 mg should be considered for patients with moderate hepatic impairment (Child-Pugh Class B). No studies have been conducted in patients with severe hepatic impairment (Child-Pugh Class C) [see Use in Specific Populations (8.7)].

Gender

In a study of 12 male and 12 female healthy subjects who received a single oral dose of KAPIDEX 60 mg, females had higher systemic exposure (AUC) (42.8% higher) than males. No dosage adjustment is necessary in patients based on gender.

Warfarin

In a study of 20 healthy subjects, co-administration of KAPIDEX 90 mg once daily for 11 days with a single 25 mg oral dose of warfarin on day 6 did not result in any significant differences in the pharmacokinetics of warfarin or INR compared to administration of warfarin with placebo. However, there have been reports of increased INR and prothrombin time in patients receiving PPIs and warfarin concomitantly [see Drug Interactions (7.2)].

Cytochrome P 450 Interactions

Dexlansoprazole is metabolized, in part, by CYP2C19 and CYP3A4 [see Clinical Pharmacology (12.3)].

In vitro studies have shown that KAPIDEX is not likely to inhibit CYP isoforms 1A1, 1A2, 2A6, 2B6, 2C8, 2C9, 2C19, 2D6, 2E1 or 3A4. As such, no clinically relevant interactions with drugs metabolized by these CYP enzymes would be expected. Furthermore, clinical drug-drug interaction studies in mainly CYP2C19 extensive and intermediate metabolizers have shown that KAPIDEX does not affect the pharmacokinetics of diazepam, phenytoin, or theophylline. The subjects' CYP1A2 genotypes in the drug-drug interaction study with theophylline were not determined.

13 NONCLINICAL TOXICOLOGY

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 per kg per day, about 1 to 40 times the exposure on a body surface (mg/m²) basis of a 50 kg person of average height (1.46 m² BSA) given the recommended human dose of lansoprazole (30 mg per 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 per kg per day (4 to 40 times the recommended lansoprazole human dose based on BSA) exceeded the low background incidence (range = 1.4 to 10%) for this strain of rat. Testicular interstitial cell adenoma also occurred in 1 of 30 rats treated with 50 mg lansoprazole per kg per day (13 times the recommended lansoprazole human dose based on BSA) in a 1-year toxicity study.

In a 24-month carcinogenicity study, CD-1 mice were treated orally with lansoprazole doses of 15 mg to 600 mg per kg per day, 2 to 80 times the recommended human 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 mg and 600 mg lansoprazole per kg per day (40 to 80 times the recommended lansoprazole human dose based on BSA) and female mice treated with 150 mg to 600 mg lansoprazole per kg per day (20 to 80 times the recommended human 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 per kg per day (10 to 80 times the recommended lansoprazole human dose based on BSA).

A 26-week p53 (+/-) transgenic mouse carcinogenicity study of lansoprazole was not positive.

Lansoprazole was negative in the Ames test, the ex vivo rat hepatocyte unscheduled DNA synthesis (UDS) test, the in vivo mouse micronucleus test and the rat bone marrow cell chromosomal aberration test. Lansoprazole was positive in in vitro human lymphocyte chromosomal aberration tests.

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 per kg per day (40 times the recommended lansoprazole human dose based on BSA) was found to have no effect on fertility and reproductive performance of male and female rats.

14 CLINICAL STUDIES

Two multi-center, double-blind, active-controlled, randomized, 8-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: KAPIDEX 60 mg daily, KAPIDEX 90 mg 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 5.

KAPIDEX 90 mg was studied and did not provide additional clinical benefit over KAPIDEX 60 mg.

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 KAPIDEX 30 mg 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 KAPIDEX remained healed over the six-month time period as confirmed by endoscopy (see Table 6).

†‡

KAPIDEX 60 mg was studied and did not provide additional clinical benefit over KAPIDEX 30 mg.

KAPIDEX 30 mg demonstrated a higher median percent of 24-hour heartburn-free days compared to placebo over the 6-month treatment period.

A multi-center, double-blind, placebo-controlled, randomized, 4-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 6 months or longer, had heartburn on at least 4 of 7 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: KAPIDEX 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.

KAPIDEX 30 mg provided statistically significantly greater percent of days with heartburn-free 24-hour periods over placebo as assessed by daily diary over 4 weeks (see Table 7). KAPIDEX 60 mg was studied and provided no additional clinical benefit over KAPIDEX 30 mg.

Table 7: Median Percentages of 24-Hour Heartburn-Free Periods During the 4 Week Treatment Period of the Symptomatic Non-Erosive GERD Study

N	Treatment Group (daily)	Heartburn-Free 24-hour Periods (%)
312	KAPIDEX 30 mg	54.9*
310	Placebo	18.5

A higher percentage of patients on KAPIDEX 30 mg had heartburn-free 24-hour periods compared to placebo as early as the first three days of treatment and this was sustained throughout the treatment period (percentage of patients on Day 3: KAPIDEX 38% versus placebo 15%; on Day 28: KAPIDEX 63% versus placebo 40%).

Please read this information carefully before you start taking KAPIDEX. Also, read this information each time you refill your prescription, in case anything has changed. Remember, this information does not take the place of talking with your doctor.

What is KAPIDEX?

KAPIDEX is a medicine called a proton pump inhibitor (PPI). Take it for as long as your doctor tells you. KAPIDEX reduces the amount of acid in your stomach.

KAPIDEX is used in adults:

• To treat heartburn related to gastroesophageal reflux disease (GERD).
• To heal acid-related damage to the lining of the esophagus (called erosive esophagitis or EE).
• To stop erosive esophagitis from coming back.

What is GERD and EE?

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.

In some cases, acid can damage the lining of your esophagus. This damage is called erosive esophagitis or EE.

Who Should Not Take KAPIDEX?

The active ingredient in KAPIDEX is dexlansoprazole. You should not take KAPIDEX if you are allergic to KAPIDEX or any of its ingredients [see What is in KAPIDEX?].

What Should I Tell My Doctor Before and While I Take KAPIDEX?

Tell your doctor about all your medical conditions. Be sure to tell your doctor if you:

• Are pregnant or could be pregnant
• Are breastfeeding
• Have liver problems

Tell your doctor about all your medicines, including any prescription and any non-prescription medicines, herbal remedies, and vitamins.

KAPIDEX and certain other medicines can affect each other. Before taking KAPIDEX, tell your doctor if you are taking:

• ampicillin
• atazanavir
• digoxin
• iron
• ketoconazole
• warfarin
• tacrolimus

How Should I Take KAPIDEX?

Take this medicine exactly as it was prescribed and for the full length of time.

You can take KAPIDEX with or without food.

KAPIDEX should be swallowed whole.

KAPIDEX capsules can also be opened and the contents sprinkled on a tablespoon of applesauce. Swallow immediately.

If you miss a dose of KAPIDEX, take your KAPIDEX as soon as you remember. If you think you took too much medicine, call your doctor.

What Are the Possible Side Effects of KAPIDEX?

The most common side effects of KAPIDEX were diarrhea, stomach pain, nausea, common cold, vomiting and gas. There are other less common side effects. If you have any symptoms, be sure to tell your doctor about them.

Call your doctor right away if you have any of the above side effects or any other side effects that worry you while using KAPIDEX. Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.

What Else Should I Know When Taking KAPIDEX?

KAPIDEX may stop your pain and other acid related symptoms, but you could still have serious stomach problems.
