A research study to evaluate the efficacy and safety of vonoprazan 10 mg, 20 mg, and 40 mg compared to placebo for relief of episodic heartburn in subjects with symptomatic non-erosive gastroesophageal reflux disease


NERD is a disease that causes occasional heartburn (called “episodic heartburn”), a burning sensation in your chest and throat without erosions or wearing away of the inner lining of the esophagus. The standard treatment for NERD is currently the use of a class of medication called proton pump inhibitors (PPI). The purpose of this study, which involves research, is to determine whether the investigational drug, vonoprazan, is safe and effective in the potential treatment of this disease compared to a placebo. The placebo looks like the investigational drug, vonoprazan, but does not contain any active substance.
Study Duration: The total duration of the study is up to 33 weeks. The Screening Period is up to 5 weeks, Placebo-controlled Treatment Period is 4 weeks, Extension Period is 20 weeks, and safety follow-up is 4 weeks after last study drug administration
Study Procedures: Include physical exams with the study doctors, laboratory assessments/blood draws, EGD, pregnancy tests, ECGs, and symptom tracking with an electronic diary.
