A Phase 2, Double-Blind, 12-Week, Multicenter Study to Assess the Safety and Effectiveness of Daily Oral Administration of Dexlansoprazole Delayed-Release Capsules in Pediatric Subjects Aged 2 to 11 Years With Symptomatic Nonerosive Gastroesophageal Reflux Disease
Gastroesophageal reflux disease (GERD) is caused by food or acid coming up from the stomach into the esophagus, repeatedly. The esophagus is the tube that carries food and liquids from the mouth to the stomach. The body uses stomach acid to break down food, but when acid rises up into the esophagus it can hurt or damage it. People with GERD often feel food coming back up into the throat and mouth and have a burning feeling in their stomach, chest, or throat, called heartburn. Other symptoms of GERD include pain in the stomach or throat, difficulty eating, and throwing up. Symptomatic nonerosive GERD is a condition where people have the symptoms of GERD but the esophagus has not been damaged. People of all ages can have GERD. The causes of GERD in children are similar to those in adults and teenagers. Dexlansoprazole is a medicine that has been shown to help relieve the symptoms of GERD in adults and teenagers. This study aims to find out if dexlansoprazole doses given to children with symptomatic nonerosive GERD, based on their body weight, helps them feel better.
• In the opinion of the investigator, the participant (as age appropriate) and/or parent(s)/legal guardian is capable of understanding and complying with protocol requirements.
• Prior to any study-specific procedures being performed, the appropriate informed consent and the assent form(s) (as applicable) must be signed and dated by parent(s) or legal guardian and by the participant respectively, if appropriate.
• Has a medical history of symptoms of GERD for at least 3 months prior to Screening.
• Has met the eDiary qualification criteria as assessed by the PGSDD, defined as hurting or burning in the stomach, chest, or throat on at least 3 of any 7 consecutive days during the Screening Period.
• Has no evidence of erosive esophagitis (EE) according to the Los Angeles (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 participant's symptoms are acid-related. An endoscopy performed within 1 week prior to signing screening informed consent and assent form (as applicable) is an acceptable replacement for the screening endoscopy if nonerosive GERD is confirmed, protocol-required biopsies were collected, and endoscopic pictures were obtained.
• Is male or female and age 2 to 11 years, inclusive, at the time of screening informed consent.
