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 20 mg once daily arm in the healing phase are presented in Table 5 . Table 5: Adverse Reactions Reported in at least 2% of patients in the VOQUEZNA arm. in a Clinical Trial of Adult Patients with All Grades of Erosive Esophagitis The trial was not designed to support comparative claims for VOQUEZNA for the adverse reactions reported in this table.

Other Clinical Trials of Erosive Esophagitis Adverse reactions reported in the United States trial were similar to those reported in 4 additional randomized, active-controlled, double-blind studies of vonoprazan compared to lansoprazole conducted outside of the United States (two 8-week trials of healing of erosive esophagitis and two 24-week maintenance of healed erosive esophagitis trials). Relief of Heartburn Associated with Non-Erosive Gastroesophageal Reflux Disease The safety of VOQUEZNA 10 mg once daily for the relief of heartburn associated with non-erosive gastroesophageal reflux disease was evaluated in a randomized, placebo-controlled, double-blind, four-week trial with a 20-week extension phase conducted in the United States [see Clinical Studies (14.3) ] . Patients initially randomized to placebo in the 4-week placebo-controlled phase were re-randomized to VOQUEZNA 10 mg once daily or a higher dosage of VOQUEZNA for 20 weeks in the extension phase. Adverse reactions reported in at least 2% of patients in the VOQUEZNA 10 mg once daily arm in the 4-week placebo-controlled phase are presented in Table 7 .

COVID-19 COVID-19 was reported in the 4-week placebo-controlled phase in 3 (1%) patients who received VOQUEZNA 10 mg once daily and 3 (1%) patients who received placebo, and in 24 (7%) patients who received VOQUEZNA 10 mg once daily in the 20-week extension phase. Less Common Adverse Reactions Adverse reactions reported in 1% or less of VOQUEZNA-treated patients for the healing or maintenance of healed erosive esophagitis or for the relief of heartburn associated with non-erosive gastroesophageal reflux disease in the United States trials are: Blood and lymphatic system disorders: anemia, lymphocytosis Cardiac disorders: tachycardia Ear and labyrinth disorders: vertigo Gastrointestinal disorders: duodenal polyp, dry mouth, dysphagia, eructation, flatulence, gastric polyps, vomiting General disorders and administrative site conditions: asthenia, peripheral edema Investigations: increased liver enzymes Metabolism and nutritional disorders: diabetes mellitus Musculoskeletal system: bone fracture Nervous system disorders: dizziness, headache, syncope Psychiatric disorders: depression, insomnia Renal and urinary disorders: tubulointerstitial nephritis Skin and subcutaneous tissue disorders: eczema, rash, urticaria Treatment of H. pylori Infection The safety of VOQUEZNA, amoxicillin and clarithromycin was evaluated in 675 adult patients (aged 20 to 82 years) in clinical trials in the United States, Europe, and Japan, and VOQUEZNA and amoxicillin was evaluated in 348 adult patients (aged 20 to 80 years) in a clinical trial in the United States and Europe. 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 (14.4) ] . 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%).
