| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial  | 
| To assess the safety and effectiveness of treatment with QD oral administration of dexlansoprazole delayed release capsules (15,30, and 60 mg) in pediatric subjects aged 2 to 11 years with symptomatic nonerosive GERD | 
 
 
 | 
| E.2.2 | Secondary objectives of the trial  | 
 | 
| E.2.3 | Trial contains a sub-study  |  No  | 
| E.3 | Principal inclusion criteria  | 
1. Medical history of GERD symptoms for at least 3 months prior to Screening and history of at least 1 failed attempted withdrawal of prior proton pump inhibitor (PPI)/acid suppressive therapy with return of symptoms upon withdrawal. 2. Reported symptoms of hurting or burning in the stomach, chest, or throat on at least 3 out of any 7 consecutive days as recorded in the eDiary during screening. 3. No evidence of erosive esophagitis according to the LA Classification of Esophagitis and, in the investigator’s clinical judgment, the symptoms are suggestive of acid-related disease. A 24-hour pH-metry (with or without impedance) may be performed during Screening or within 6 months prior to Screening for similar symptoms as those identified during Screening if, in the investigator’s judgment, this procedure would aid in the determination of whether the subject’s symptoms are acid-related. | 
 
 
 | 
| E.4 | Principal exclusion criteria | 
1. Erosive esophagitis. 2. History of hypersensitivity or allergies to dexlansoprazole or any component of dexlansoprazole or antacid or any PPI (including lansoprazole, omeprazole, rabeprazole, pantoprazole, or esomeprazole). 3. Evidence of cardiovascular, pulmonary, central nervous system, hepatic, hematopoietic, renal, or metabolic disorder, severe allergy, asthma, or allergic skin rash that suggests any uncontrolled, clinically significant underlying disease or condition (other than the disease being studied), which may impact the ability of the subject to participate or potentially confound the study results. 4. Any findings in medical history, physical examination, or safety clinical laboratory tests giving reasonable suspicion of underlying disease that might interfere with the conduct of the trial. 5. Known history of Barrett’s esophagus with dysplastic changes in the esophagus. 6. History of the following: eosinophilic esophagitis (EoE) or histologic findings suggestive of EoE (>15 eosinophils per high-powered field [HPF]); a history of celiac disease or tests positive for tissue transglutaminase (tTG) antibody or confirmed disease by histology; inflammatory bowel disease; or irritable bowel syndrome. 7. Active gastric or duodenal ulcers within 4 weeks prior to Day -1. 8. Subjects who are required to take prescription or nonprescription medications as listed in Excluded Medications and Treatment Section of the protocol (Section 7.3). |
