- VOQUEZNA is contraindicated with rilpivirine-containing products [see Drug Interactions (7)].
- For information about contraindications of antibacterial agents (clarithromycin and amoxicillin) indicated in combination with VOQUEZNA, refer to the Contraindications section of the corresponding prescribing information.
-
5 WARNINGS AND PRECAUTIONS
5.1 Presence of Gastric Malignancy
In adults, symptomatic response to therapy with VOQUEZNA does not preclude the presence of gastric malignancy. Consider additional follow-up and diagnostic testing in patients who have a suboptimal response or an early symptomatic relapse after completing treatment with VOQUEZNA. In older patients, also consider endoscopy.
5.2 Acute Tubulointerstitial Nephritis
Acute tubulointerstitial nephritis (TIN) has been reported with VOQUEZNA [see Adverse Reactions (6.1)]. If suspected, discontinue VOQUEZNA and evaluate patients with suspected acute TIN.
5.3 Clostridioides difficile-Associated Diarrhea
Published observational studies suggest that proton pump inhibitors (PPIs) may be associated with an increased risk of Clostridioides difficile-associated diarrhea (CDAD), especially in hospitalized patients. VOQUEZNA, another drug that blocks the proton pump to inhibit gastric acid production, may also increase the risk of CDAD. Consider CDAD in patients with diarrhea that does not improve [see Adverse Reactions (6.2)]. Use the shortest duration of VOQUEZNA appropriate to the condition being treated.
CDAD has been reported with use of nearly all antibacterial agents. For more information specific to antibacterial agents (clarithromycin and amoxicillin) indicated for use in combination with VOQUEZNA, refer to Warnings and Precautions section of the corresponding prescribing information.
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 therapy (a year or longer). Bone fracture, including osteoporosis-related fracture, has also been reported with vonoprazan. Use the shortest duration of VOQUEZNA appropriate to the condition being treated [see Dosage and Administration (2.1)]. Patients at risk for osteoporosis-related fractures should be managed according to the established treatment guidelines.
5.5 Severe Cutaneous Adverse Reactions
Severe cutaneous adverse reactions, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) have been reported with VOQUEZNA [see Adverse Reactions (6.2)].
Discontinue VOQUEZNA at the first signs or symptoms of severe cutaneous adverse reactions or other signs of hypersensitivity and consider further evaluation.
5.6 Vitamin B12 (Cobalamin) Deficiency
Long-term use of acid-suppressing drugs can lead to malabsorption of Vitamin B12 caused by hypo- or achlorhydria. Vitamin B12 deficiency has been reported postmarketing with vonoprazan [see Adverse Reactions (6.2)]. If clinical symptoms consistent with Vitamin B12 deficiency are observed in patients treated with VOQUEZNA consider further workup.
5.7 Hypomagnesemia and Mineral Metabolism
Hypomagnesemia has been reported postmarketing with vonoprazan [see Adverse Reactions (6.2)]. Hypomagnesemia may lead to hypocalcemia and/or hypokalemia and may exacerbate underlying hypocalcemia in at-risk patients.
Consider monitoring magnesium levels prior to initiation of VOQUEZNA and periodically in patients expected to be on prolonged treatment, in patients taking drugs that may have increased toxicity in the presence of hypomagnesemia (e.g., digoxin), or drugs that may cause hypomagnesemia (e.g., diuretics). Treatment of hypomagnesemia may require magnesium replacement and discontinuation of VOQUEZNA.
Consider monitoring magnesium and calcium levels prior to initiation of VOQUEZNA and periodically while on treatment in patients with a preexisting risk of hypocalcemia (e.g., hypoparathyroidism). Supplement with magnesium and/or calcium, as necessary. If hypocalcemia is refractory to treatment, consider discontinuing VOQUEZNA.
5.8 Interactions with Diagnostic 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. Temporarily discontinue VOQUEZNA 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 [see Drug Interactions (7) and Clinical Pharmacology (12.2)].
5.9 Fundic Gland Polyps
Use of VOQUEZNA is associated with a risk of fundic gland polyps that increases with long-term use, especially beyond one year. Fundic gland polyps have been reported with vonoprazan in clinical trials and postmarketing use with PPIs. Most patients who developed fundic gland polyps were asymptomatic and fundic gland polyps were identified incidentally on endoscopy. Use the shortest duration of VOQUEZNA appropriate to the condition being treated [see Dosage and Administration (2.1)].

6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Healing of Erosive Esophagitis and Maintenance of Healed Erosive Esophagitis
The safety of VOQUEZNA was evaluated in a randomized, active-controlled, double-blind two phase trial for the healing of erosive esophagitis (2 to 8 weeks) and maintenance of healed erosive esophagitis (through 24 weeks) conducted in the United States and Europe [see Clinical Studies (14.1), (14.2)].
Adverse reactions reported in at least 2% of patients in the VOQUEZNA arm in the healing phase are presented in Table 5.

All of the patients were screened and found to be positive for H. pylori infection.
The safety of VOQUEZNA, amoxicillin and clarithromycin (triple therapy) and VOQUEZNA and amoxicillin (dual therapy) was evaluated in a randomized, controlled, double-blind (triple therapy)/open-label (dual therapy) study conducted in the United States and Europe in treatment-naïve H. pylori-positive adult patients [see Clinical Studies (14.3)].
Adverse Reactions Leading to Discontinuation
Treatment discontinuation due to an adverse reaction occurred in 2.3% (8/346) of the patients treated with VOQUEZNA, amoxicillin and clarithromycin, 0.9% (3/348) of the patients treated with VOQUEZNA and amoxicillin, and 1.2% (4/345) of the patients treated with lansoprazole, amoxicillin and clarithromycin. The most common adverse reactions leading to discontinuation of VOQUEZNA, amoxicillin and clarithromycin were diarrhea (0.6%) and hypertension (0.6%) and the most common adverse reaction leading to discontinuation of VOQUEZNA and amoxicillin was rash (0.6%).

7 DRUG INTERACTIONS
Table 8 and Table 9 include drugs with clinically important drug interactions and interaction with diagnostics when administered concomitantly with VOQUEZNA and instructions for preventing or managing them.
These recommendations are based on either drug interaction trials or predicted interactions due to the expected magnitude of interaction and potential for serious adverse reactions or loss of efficacy [see Clinical Pharmacology (12.3)].
Consult the labeling of concomitantly used drugs to obtain further information about interactions with vonoprazan.
Table 8: Drug Interactions Affecting Drugs Co-Administered with VOQUEZNA and Interactions with Diagnostics Drugs Dependent on Gastric pH for Absorption Antiretrovirals Clinical Effect
Vonoprazan reduces intragastric acidity [see Clinical Pharmacology (12.2)] which may alter the absorption of antiretroviral drugs leading to changes in the safety and/or effectiveness. Prevention or Management Rilpivirine-containing products Concomitant use with VOQUEZNA is contraindicated. Atazanavir Avoid concomitant use with VOQUEZNA. Nelfinavir Other antiretrovirals See the prescribing information of other antiretroviral drugs dependent on gastric pH for absorption prior to concomitant use with VOQUEZNA. Other Drugs (e.g., iron salts, erlotinib, dasatinib, nilotinib, mycophenolate mofetil, ketoconazole/itraconazole) Clinical Effect Vonoprazan reduces intragastric acidity [see Clinical Pharmacology (12.2)], which may decrease the absorption of drugs reducing their effectiveness. Prevention or Management See the prescribing information for other drugs dependent on gastric pH for absorption. Combination Therapy with Clarithromycin and/or Amoxicillin Clinical Effect Concomitant administration of clarithromycin with other drugs can lead to serious adverse reactions, including potentially fatal arrhythmias, and are contraindicated. Amoxicillin also has drug interactions. Prevention or Management See Contraindications and Warnings and Precautions in the prescribing information for clarithromycin.
See Drug Interactions in the prescribing information for amoxicillin.Certain CYP3A Substrates where minimal concentration changes may lead to serious toxicities Clinical Effect Vonoprazan is a weak CYP3A inhibitor [see Clinical Pharmacology (12.3)].
Vonoprazan may increase exposure of CYP3A4 substrates, which may increase the risk of adverse reactions related to these substrates.Prevention or Management Frequent monitoring for concentrations and/or adverse reactions related to the substrate drugs when used with VOQUEZNA. Dosage reduction of substrate drugs may be needed.
See prescribing information for the relevant substrate drugs.CYP2C19 Substrates (e.g., clopidogrel, citalopram, cilostazol) Clinical Effect Vonoprazan is a CYP2C19 inhibitor [see Clinical Pharmacology (12.3)]. Vonoprazan may reduce plasma concentrations of the active metabolite of clopidogrel and may cause reduction in platelet inhibition. Vonoprazan may increase exposure of CYP2C19 substrate drugs (e.g., citalopram, cilostazol). Prevention or Management Clopidogrel Carefully monitor the efficacy of clopidogrel and consider alternative anti-platelet therapy. Citalopram and Cilostazol Carefully monitor patients for adverse reactions associated with citalopram and cilostazol. See the prescribing information for dosage adjustments. Chromogranin (CgA) Test for Neuroendocrine Tumors Clinical Effect Vonoprazan reduces intragastric acidity [see Clinical Pharmacology (12.2)], which increases CgA levels and may cause false positive results in diagnostic investigations for neuroendocrine tumors. Prevention or Management Assess CgA levels at least 14 days after stopping VOQUEZNA treatment and repeat the test if initial CgA levels are high. If serial tests are performed (e.g., for monitoring), use the same commercial laboratory for testing, as reference ranges between tests may vary. Interaction with Secretin Stimulation Test Clinical Effect Hyper-response in gastrin secretion in response to secretin stimulation test, falsely suggesting gastrinoma. Prevention or Management Temporarily stop VOQUEZNA at least 14 days before assessing to allow gastrin levels to return to baseline [see Clinical Pharmacology (12.2)]. Table 9: Drug Interactions Affecting VOQUEZNA When Co-Administered with Other Drugs Strong or Moderate CYP3A4 Inducers Clinical Effect Vonoprazan is a CYP3A substrate. Strong or moderate CYP3A inducers decrease vonoprazan exposure [see Clinical Pharmacology (12.3)], which may reduce the effectiveness of VOQUEZNA. Prevention or Management Avoid concomitant use with VOQUEZNA. -
8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Risk Summary
There are no adequate and well-controlled studies of vonoprazan in pregnant women. Available data from pharmacovigilance reports with vonoprazan-containing products use in pregnant women are not sufficient to evaluate for a drug-associated risk for major birth defects, miscarriage, or other adverse maternal or fetal outcomes.
In pregnant rats, no adverse effects were noted after oral administration of vonoprazan during organogenesis at approximately 27-times the maximum recommended human dose (MRHD) based on AUC exposure comparisons.
In a pre- and postnatal development (PPND) study, pups from dams orally administered vonoprazan during organogenesis and through lactation, exhibited liver discoloration, which in follow-up mechanistic animal studies was associated with necrosis, fibrosis, and hemorrhage at a dose approximately 22-times the MRHD based on AUC comparisons which were likely attributable to exposure during lactation [see Use in Specific Populations (8.2)]. These effects were not observed at the next lower dose in this study, which was approximately equal to the MRHD based on AUC comparison, however they were seen at clinically relevant exposures in dose range finding studies in rats (see Data).
The estimated background risks of major birth defects and miscarriage for the indicated population are unknown. All pregnancies have a background risk of birth defects, loss, or other adverse outcomes. In the United States 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.
Report pregnancies to the Phathom Pharmaceuticals, Inc. Adverse Event reporting line at 1-888-775-7428.
Data
Animal Data
Pregnant rats were orally administered vonoprazan at doses of 30, 100, or 300 mg/kg/day (7-, 27-, 130-times the MRHD based on AUC comparison at the same doses from unmated female rats from separate studies) during the period of organogenesis from gestation day (GD) 6 to 17. During maternal dosing, one high-dose female died and decreased body weight and food consumption occurred at the middle and highest doses. No embryo-fetal lethality was observed but decreased fetal body weight was observed in the highest dose group. Fetal abnormalities were limited to the 300 mg/kg/day and included ventricular septal defect and mal-positioned subclavian artery in fetuses in a majority (15/19) of litters, as well as tail abnormalities and small anal opening. No adverse embryo-fetal effects were observed at the 100 mg/kg/day.
Pregnant rabbits were orally administered vonoprazan at doses of 3, 10, or 30 mg/kg/day (0.04-, 1.5-, 10-times the MRHD based on AUC comparison) during the period of organogenesis from GD 6 to 18. Two animals aborted at the highest dose and decreased body weight and food consumption occurred at the mid and high doses. No embryo-fetal mortality or toxicity occurred. There were no external, visceral or skeletal abnormalities.
In a PPND study, pregnant female rats were orally administered vonoprazan at doses of 1, 3, 10, or 100 mg/kg/day (0.01-, 0.18-, 1.1-, 22-times the MRHD based on AUC comparison) from GD 6 to lactation day (LD) 21. Decreased body weight gain and food consumption were present in dams at the highest dose during lactation. Decreased body weight gain compared to controls was observed in the offspring from dams in the high dose group. Liver discoloration occurred in offspring from the high dose group at LD 4 but was not present in animals examined after weaning. Similarly, in dose range finding studies in rats and follow-up mechanistic animal studies, the liver discoloration was observed and characterized as necrosis, fibrosis, and hemorrhage at equal to or greater than clinically relevant exposures based on AUC comparisons. The mechanistic studies further demonstrated the effect was likely attributable to vonoprazan exposure during lactation [see Use in Specific Populations (8.2)]. The clinical relevance of the liver findings is uncertain.
Exposure margins from vonoprazan between the animal and clinical studies for vonoprazan, amoxicillin and clarithromycin used in combination may be lower due to increased vonoprazan exposure from concomitant use with clarithromycin in patients [see Clinical Pharmacology (12.3)].
8.2 Lactation
Risk Summary
There are no data regarding the presence of vonoprazan in human milk, the effects on the breastfed infant, or the effects on milk production. Vonoprazan and its metabolites are present in rat milk. Liver injury occurred in offspring from pregnant and lactating rats administered oral vonoprazan at AUC exposures approximately equal to and greater than the MRHD (see Data). When a drug is present in animal milk, it is likely that the drug will be present in human milk. Because of the potential risk of adverse liver effects shown in animal studies with vonoprazan, advise patients not to breastfeed during treatment with VOQUEZNA.
Data
Animal Data
In a PPND study in rats, in which the dams were administered oral vonoprazan during gestation and through lactation at up to 22-times the MRHD (based on AUC comparison), liver discoloration occurred in offspring from the high dose group [see Use in Specific Populations (8.1)].
Liver discoloration associated with necrosis, fibrosis, and hemorrhage in the offspring of dosed rats was also seen in dose-range finding studies and follow-up, mechanistic studies, including offspring in lactation only studies. These effects were reported in pups on LD 4 at doses from 3 to 100 mg/kg/day (approximately 0.2- to 22-fold the MRHD based on AUC values extrapolated from the PPND study) and on LD 14 at doses from 10 to 100 mg/kg/day dose groups (approximately 1- to 22-fold the MRHD based on an extrapolated AUC comparisons). In mechanistic studies, liver effects were observed in offspring treated only during lactation but not in offspring from animals only treated during gestation. In some of these studies, this finding was associated with increased offspring stomach weights that was reversed along with liver discoloration by concomitant treatment with a gastrointestinal prokinetic agent.
8.4 Pediatric Use
The safety and effectiveness of VOQUEZNA have not been established in pediatric patients.
8.5 Geriatric Use
There were 200 patients aged 65 years and older in the clinical trial for erosive esophagitis and relief of heartburn [see Clinical Studies (14.1)]. Of the total number of vonoprazan-treated patients there were 93 (18%) patients aged 65 years of age and older and 10 (2%) patients aged 75 years of age and older.
There were 218 patients aged 65 years and older in the clinical trial for the treatment of H. pylori infection [see Clinical Studies (14.3)]. Of the total number of vonoprazan-treated patients, there were 153 (22%) patients aged 65 years of age and older and 18 (3%) patients aged 75 years of age and older.
No overall differences in safety or effectiveness were observed between these patients and younger adult patients, and other reported clinical experience has not identified differences in responses between the geriatric and younger adult patients, but greater sensitivity of some older individuals cannot be ruled out.
No clinically meaningful differences in the pharmacokinetics of vonoprazan are predicted in patients 65 years of age and older compared to younger adult patients [see Clinical Pharmacology (12.3)].
8.6 Renal Impairment
Healing of Erosive Esophagitis
No dosage adjustment of VOQUEZNA for the healing of erosive esophagitis is recommended in patients with mild to moderate renal impairment (eGFR 30 to 89 mL/min). Dosage reduction is recommended in patients with severe renal impairment (eGFR < 30 mL/min) [see Dosage and Administration (2.2) and Clinical Pharmacology (12.3)].
Maintenance of Healed Erosive Esophagitis
No dosage adjustment of VOQUEZNA for the maintenance of healed erosive esophagitis is recommended in patients with any degree of renal impairment.
Treatment of H. pylori Infection
Use of VOQUEZNA is not recommended for the treatment of H. pylori infection in patients with severe renal impairment (eGFR < 30 mL/min) [see Dosage and Administration (2.2) and Clinical Pharmacology (12.3)].
8.7 Hepatic Impairment
Healing of Erosive Esophagitis
No dosage adjustment of VOQUEZNA for the healing of erosive esophagitis is recommended in patients with mild hepatic impairment (Child-Pugh A). Dosage reduction is recommended in patients with moderate to severe hepatic impairment (Child-Pugh Class B and C) [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3)].
Maintenance of Healed Erosive Esophagitis
No dosage adjustment of VOQUEZNA for the maintenance of healed erosive esophagitis is recommended in patients with any degree of hepatic impairment.
Treatment of H. pylori Infection
Use of VOQUEZNA is not recommended for the treatment of H. pylori infection in patients with moderate to severe hepatic impairment (Child-Pugh Class B and C) [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3)].

11 DESCRIPTION
Vonoprazan (as the fumarate), is a potassium-competitive acid blocker. Chemically, it is 1H-pyrrole-3-methanamine, 5-(2-fluorophenyl)-N-methyl-1-(3-pyridinylsulfonyl)-, (2E)-2-butenedioate (1:1). Its empirical formula is C17H16FN3O2S•C4H4O4 with a molecular weight of 461.5. Vonoprazan fumarate has the following structure:
Vonoprazan fumarate is white to nearly white crystals or crystalline powder which melts at 194.8°C. Vonoprazan fumarate is soluble in dimethyl sulfoxide; sparingly soluble in N,N–dimethylacetamide, slightly soluble in N,N-dimethylformamide, methanol and water; very slightly soluble in ethanol (99.5%); and practically insoluble in 2-propanol, acetone, 1-octanol, and acetonitrile.
VOQUEZNA (vonoprazan) tablets are available in two dosage strengths for oral administration: 10 mg of vonoprazan (equivalent to 13.36 mg of vonoprazan fumarate) and 20 mg of vonoprazan (equivalent to 26.72 mg of vonoprazan fumarate). Each film-coated tablet contains the following inactive ingredients: ascorbic acid, croscarmellose sodium, ferric oxide red (only in 20 mg tablets), ferric oxide yellow (only in 10 mg tablets), fumaric acid, hydroxypropyl cellulose, hypromellose, magnesium stearate, mannitol, microcrystalline cellulose, polyethylene glycol 8000, and titanium dioxide.

12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Vonoprazan suppresses basal and stimulated gastric acid secretion at the secretory surface of the gastric parietal cell through inhibition of the H+, K+-ATPase enzyme system in a potassium competitive manner. Because this enzyme is regarded as the acid (proton) pump within the parietal cell, vonoprazan has been characterized as a type of gastric proton-pump inhibitor, in that it blocks the final step of acid production. Vonoprazan does not require activation by acid. Vonoprazan may selectively concentrate in the parietal cells in both the resting and stimulated states. Vonoprazan binds to the active pumps in a noncovalent and reversible manner.
12.2 Pharmacodynamics
Antisecretory Activity
Following a single 10 mg or 20 mg dose of vonoprazan, the onset of the antisecretory effect as measured by intragastric pH occurs within 2 to 3 hours. The elevated intragastric pH levels compared to placebo increase with dose and are maintained for over 24 hours after dosing. The inhibitory effect of vonoprazan on acid secretion increases with repeated daily dosing and steady state is achieved by Day 4. The antisecretory effect of vonoprazan decreases following drug discontinuation although intragastric pH remained elevated compared to placebo for 24 to 48 hours following the dose on Day 7.
The effects of vonoprazan 10 mg or 20 mg once daily for 7 days on 24-hour intragastric pH in healthy subjects are shown in Table 10.

(14 h)Cardiac Electrophysiology
At a single dose of 120 mg (6-times the maximum recommended dose), vonoprazan does not prolong the QT interval to any clinically relevant extent.
Serum Gastrin Effects
The effect of vonoprazan on serum gastrin concentrations was evaluated in 514 patients for up to 8 weeks (healing phase) and in 592 patients for up to 6 months (maintenance phase). During the healing phase, the mean fasting gastrin levels at Week 2 increased from baseline after treatment with VOQUEZNA 20 mg and levels were similar at Week 2 and Week 8. In the 6-month maintenance phase, the mean gastrin levels remained elevated with VOQUEZNA 10 mg and 20 mg and the mean serum gastrin levels returned to normal within 4 weeks 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 (5.8) and Drug Interactions (7)].
Enterochromaffin-Like Cell (ECL) Effects
Human gastric biopsy specimens were obtained from 135 patients treated with vonoprazan 10 mg or 20 mg once daily for up to 260 weeks. An increase in the incidence of hyperplasia of the parietal cells and G-cells was observed, which is consistent with the pharmacological action of a potassium-competitive acid blocker. No neoplastic changes were observed [see Nonclinical Toxicology (13.1), (13.2)].
12.3 Pharmacokinetics
Steady state pharmacokinetic (PK) parameters for vonoprazan 10 mg or 20 mg following once daily administration and vonoprazan 20 mg following twice daily administration from data collected across multiple studies are summarized in Table 11.

Vonoprazan exhibits time independent pharmacokinetics and steady state concentrations are achieved by Day 3 to 4. After multiple doses of vonoprazan ranging from 10 to 40 mg (twice the maximum recommended dose) once daily for 7 days in healthy subjects, Cmax and area under the plasma concentration time curve (AUC) values for vonoprazan increased in an approximately dose-proportional manner.
There is little accumulation in plasma after once daily multiple doses, with an accumulation index ratio of less than 1.2 based on AUC for doses ranging from 10 to 40 mg (twice the maximum recommended dose).
Steady state plasma exposure of vonoprazan following 20 mg twice daily dosing (AUC0-12h = 273 hr*ng/mL, N=10) was approximately 1.8-fold higher compared to the mean estimate from the same subjects on Day 1 (AUC0-12h = 155 hr*ng/mL, N=10).
Effect of Food
In a food effect study in healthy subjects (N=24) who received vonoprazan 20 mg, a high-fat meal resulted in a 5% increase in Cmax, a 15% increase in AUC, and a delay in median Tmax of 2 hours. These changes are not considered to be clinically significant [see Dosage and Administration (2.4)].
Distribution
Plasma protein binding of vonoprazan ranged from 85 to 88% in healthy subjects and was independent of concentration from 0.1 to 10 mcg/mL.
Elimination
Metabolism
Vonoprazan is metabolized to inactive metabolites via multiple pathways by a combination of cytochrome P450 (CYP) isoforms (CYP3A4/5, CYP2B6, CYP2C19, CYP2C9 and CYP2D6) along with sulfo- and glucuronosyl-transferases. CYP2C19 polymorphisms have been evaluated in clinical studies and there were no considerable differences in the pharmacokinetics of vonoprazan based on CYP2C19 metabolizer status.
Specific Populations
Geriatric Patients
No clinically meaningful differences in the pharmacokinetics of vonoprazan are predicted in patients 65 years of age and older compared to younger adult patients.
Sex, Race or Ethnicity
There were no clinically significant differences in the pharmacokinetics of vonoprazan based on sex or race/ethnicity.
Patients with Renal impairment
The pharmacokinetics of vonoprazan administered as a single 20 mg dose in patients with mild [eGFR 60 to <90 mL/min/1.73m2 (N=8)], moderate [eGFR 30 to <60 mL/min/1.73m2 (N=8)], or severe [eGFR 15 to <30 mL/min/1.73m2 (N=8)] renal impairment were compared to those with normal renal function [eGFR ≥90 mL/min/1.73m2 (N=13)]. Compared to subjects with normal renal function, systemic exposure (AUC0-inf) was 1.7-, 1.3-, and 2.4-times greater in patients with mild, moderate, and severe renal impairment, respectively. In subjects requiring dialysis (N=8), AUC0-inf estimates were 1.3-fold greater compared to estimates from subjects with normal renal function [see Dosage and Administration (2.2)]. Protein binding of vonoprazan is not affected by impaired renal function. In patients requiring dialysis, vonoprazan was present in the dialysate and represented 0.94% of the dose administered.
Patients with Hepatic Impairment
The pharmacokinetics of vonoprazan administered as a single 20 mg dose in patients with mild [Child-Pugh Class A (N=8)], moderate [Child-Pugh Class B (N=8)], or severe [Child-Pugh Class C (N=6)] hepatic impairment were compared to those with normal hepatic function (N=12). Compared to subjects with normal hepatic function, systemic exposure (AUC0-inf) of vonoprazan was 1.2-, 2.4-, and 2.6-times greater in patients with mild, moderate, and severe hepatic impairment, respectively [see Dosage and Administration (2.3)]. Protein binding of vonoprazan is not affected by impaired hepatic function.
Drug Interaction Studies
Clinical Studies
Combination Therapy with Vonoprazan, Amoxicillin, and Clarithromycin
When vonoprazan 20 mg, amoxicillin 750 mg and clarithromycin 400 mg were co-administered twice daily for 7 days (N=11), there was no effect on pharmacokinetics of amoxicillin compared to amoxicillin alone. However, vonoprazan Cmax and AUC0-12h increased by 87% and 85%, respectively, and clarithromycin Cmax and AUC0-12h increased by 64% and 45% respectively, compared to administration of each component alone.
Effect of Vonoprazan on CYP3A4 Substrates
When a single oral dose of midazolam 2 mg was administered following vonoprazan 20 mg twice daily for 7 days (N=20), midazolam AUC0-inf increased 93% compared to administration of midazolam alone.
Effect of CYP3A Inhibitors on Vonoprazan
When a single dose of 40 mg vonoprazan (twice the maximum recommended dose) was administered with clarithromycin 500 mg twice daily for 7 days (N=16), vonoprazan AUC0-inf increased 58% compared to administration of vonoprazan alone.
Coadministration of Vonoprazan with NSAIDs or Low Dose Aspirin
When a single dose of 40 mg vonoprazan (twice the maximum recommended dose) was co-administered with diclofenac 25 mg, meloxicam 10 mg, or aspirin 100 mg, there were no clinically meaningful changes in exposure of vonoprazan, diclofenac, meloxicam, or aspirin compared to administration of each drug alone.
12.4 Microbiology
Antimicrobial Activity
Culture and sensitivity testing of bacteria are not routinely performed to establish the diagnosis of H. pylori infection [see Clinical Studies (14.3)]. The following in vitro data are available, but their clinical significance is unknown. Clarithromycin and amoxicillin are active in vitro against most isolates of H. pylori.

13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Carcinogenicity
In a 24-month carcinogenicity study in mice, vonoprazan at daily oral doses of 6, 20, 60, and 200 mg/kg/day (approximately 0.4-, 4-, 19-, and 93-times the MRHD based on AUC) produced hyperplasia of neuroendocrine cells, gastropathy and benign and/or malignant neuroendocrine cell tumors (carcinoids) in the stomach at all doses in males and at 60 mg/kg/day and greater in females. In liver, increased incidences of hepatocellular adenoma and carcinomas were observed at doses of 20 mg/kg/day and greater in males and 60 mg/kg/day and greater in females.
In a 24-month carcinogenicity study in Sprague-Dawley rats, vonoprazan at daily oral doses of 5, 15, 50, and 150 mg/kg/day (approximately 0.6-, 4-, 19-, and 65-times the MRHD based on AUC) produced benign and/or malignant neuroendocrine cell tumors in the stomach in both male and female rats at doses of 5 mg/kg/day or more. Increased incidence of hepatocellular adenoma and carcinomas and hepatocholangiocellular adenomas and carcinomas were observed at doses of 50 and 150 mg/kg/day.
In both mice and rats, neuroendocrine tumors in the stomach occurred in association with neuroendocrine hyperplasia and gastropathy in the stomach and increased plasma gastrin concentrations that are consistent with inhibition of gastric acid secretion. Carcinoid tumors have also been observed in rats subjected to fundectomy or long-term treatment with proton pump inhibitors or high doses of H2-receptor antagonists.
Mutagenesis
Vonoprazan was negative for mutagenicity in the in vitro Ames test, in an in vitro clastogenecity assay in Chinese Hamster cells and in vivo in a rat bone marrow micronucleus study.
Impairment of Fertility
Vonoprazan at oral doses up to 300 mg/kg/day in rats (approximately 133-times the MRHD based on AUC from a separate study in nonpregnant animals administered the same dose) was found to have no effect on fertility and reproductive performance. Elongation of the estrous cycle was observed in rats at doses equivalent to 133-times the MRHD based on AUC.
13.2 Animal Toxicology and/or Pharmacology
During lifetime exposure of mice and rats dosed daily with up to 200 mg/kg/day and 150 mg/kg/day of vonoprazan respectively, increases in gastrin levels and marked neuroendocrine hyperplasia and gastropathy were observed followed by formation of carcinoid tumors [see Nonclinical Toxicology (13.1)]. This finding is considered to be a rodent-specific phenomenon.

14 CLINICAL STUDIES
14.1 Healing of Erosive Esophagitis and Relief of Heartburn
The effectiveness and safety of VOQUEZNA was evaluated in a randomized, active-controlled, double-blind, eight-week study conducted in the United States and Europe in 1024 adult patients with endoscopically confirmed erosive esophagitis (NCT04124926). Severity of the disease was classified based on the Los Angeles (LA) Classification Grading System (Grades A through D). Patients were randomized to one of the following treatment groups: VOQUEZNA 20 mg once daily or lansoprazole 30 mg once daily for 2 to 8 weeks. Patients who were positive for H. pylori infection or who had Barrett's esophagus and/or definite dysplastic changes in the esophagus at baseline were excluded from the study. Based on the LA Classification, 66% of patients had mild erosive esophagitis (Grades A or B) and 34% of patients had moderate to severe erosive esophagitis (Grades C or D) prior to randomization. Patients in the trial had a mean age of 51 years (range 18 to 84 years); 53% were female; 12% identified as Hispanic or Latino; 91% identified as White, 6% as Black or African American, and 3% identified as another racial group.
Healing of erosive esophagitis was assessed at Week 2 and Week 8 and resolution of heartburn symptoms was evaluated daily over the 8-week period. If endoscopic healing of erosive esophagitis was confirmed at Week 2, the patient entered the maintenance phase of the study. If endoscopic healing was not confirmed at Week 2, the patient continued to receive randomized treatment until Week 8. Only patients with confirmed endoscopic healing entered the maintenance phase. All endoscopies were centrally read and adjudicated.
Healing of All Grades of Erosive Esophagitis
The primary endpoint, was endoscopically confirmed complete healing of all grades of erosive esophagitis at Week 2 or Week 8, as shown in Table 12.

For the secondary endpoint of complete healing of erosive esophagitis at Week 2, superiority was demonstrated in the subgroup of patients with LA Grade C or D disease, 70% of 177 VOQUEZNA treated patients and 53% of 174 lansoprazole treated patients achieved healing (18% treatment difference; 95% CI 7.4, 27.4).
Complete healing of erosive esophagitis at either Week 2 or Week 8 in the subgroup of patients with LA Grade C or D disease was 92% in patients treated with VOQUEZNA and 72% in patients treated with lansoprazole. This endpoint was not statistically significant under the prespecified multiple testing procedure.

Two additional randomized, active-controlled, double-blind studies conducted outside of the United States, of similar design to the United States trial, also demonstrated non-inferiority of vonoprazan 20 mg once daily compared to lansoprazole 30 mg once daily for the primary endpoint of healing of all grades of erosive esophagitis by Week 8.
14.2 Maintenance of Healed Erosive Esophagitis and Relief of Heartburn
Patients who completed the healing phase of the erosive esophagitis study (NCT04124926) and showed endoscopically confirmed healed erosive esophagitis at Week 2 or Week 8 were re-randomized in the maintenance phase 1:1:1 to either VOQUEZNA 10 mg once daily, a higher dosage of VOQUEZNA, or lansoprazole 15 mg once daily. Maintenance of healing and resolution of heartburn symptoms were evaluated over 24 weeks. The higher VOQUEZNA dose group did not demonstrate additional treatment benefit compared to VOQUEZNA 10 mg once daily.
Maintenance of Healed Erosive Esophagitis
The primary endpoint was maintenance of healed erosive esophagitis (all grades) through Week 24. A secondary endpoint was maintenance of healed erosive esophagitis in the subgroup of patients with LA Grade C or D disease prior to randomization in the healing phase of the study.
The maintenance rates of healed erosive esophagitis are shown in Table 14.

Two additional randomized, active-controlled, double-blind studies conducted outside of the United States, of similar design to the United States trial, also demonstrated non-inferiority of vonoprazan 10 mg once daily compared to lansoprazole 15 mg once daily for the primary endpoint of maintenance of healed erosive esophagitis (all grades) through Week 24.
14.3 Treatment of Helicobacter pylori Infection
The effectiveness and safety of VOQUEZNA, amoxicillin and clarithromycin (triple therapy) and VOQUEZNA and amoxicillin (dual therapy) were evaluated in a randomized, controlled, double-blind (triple therapy)/open-label (dual therapy) study conducted in the United States and Europe in treatment-naïve H. pylori-positive adult patients with at least one clinical condition: dyspepsia lasting at least 2 weeks, functional dyspepsia, recent/new diagnosis of peptic ulcer, peptic ulcer not treated for H. pylori infection, or a stable dose of long-term NSAID treatment (NCT04167670). Patients were randomized 1:1:1 to one of the following regimens administered for 14 consecutive days:
- VOQUEZNA 20 mg twice daily plus, amoxicillin 1,000 mg twice daily, and clarithromycin 500 mg twice daily
- VOQUEZNA 20 mg twice daily and amoxicillin 1,000 mg three times daily
- lansoprazole 30 mg twice daily, amoxicillin 1,000 mg twice daily, and clarithromycin 500 mg twice daily
H. pylori infection at baseline was defined as positive by 13C urea breath test (UBT) and follow-up upper endoscopy (culture or histology). H. pylori eradication was confirmed with a negative 13C UBT test-of-cure at least 27 days post-therapy. Patients with negative test results were considered treatment successes. Patients who tested positive for H. pylori infection and patients with missing results from the test-of-cure visit were considered treatment failures.
A total of 346 patients received VOQUEZNA, amoxicillin, and clarithromycin, 348 patients received VOQUEZNA and amoxicillin, and 345 patients received lansoprazole, amoxicillin, and clarithromycin. These patients had a mean age of 51 years (range 20 to 87 years); 62% were female; 27% identified as Hispanic or Latino; 89% identified as White, 7% as Black or African American, 2% as Asian, and 2% identified as another racial group.
VOQUEZNA, amoxicillin, and clarithromycin and VOQUEZNA and amoxicillin were shown to be noninferior to lansoprazole, amoxicillin, and clarithromycin in patients who did not have a clarithromycin or amoxicillin resistant strain of H. pylori at baseline. VOQUEZNA, amoxicillin, and clarithromycin and VOQUEZNA and amoxicillin were shown to be superior to lansoprazole, amoxicillin, and clarithromycin in patients who had a clarithromycin resistant strain of H. pylori at baseline and in the overall population.
H. pylori eradication rates at least 27 days post-therapy are shown in Table 16.
