|
|

The secondary objectives of this study were:
· to assess the difference between esomeprazole and placebo in the treatment of symptomatic reflux episodes of GERD
· to assess the difference between esomeprazole and placebo in the treatment of other GERD-related signs and symptoms via video, pH/impedance, and cardiorespiratory monitoring
· to assess the efficacy of esomeprazole, compared to placebo, in reducing the number of (a) all types of reflux episodes (acid or non-acid) and (b) acidic reflux episodes, defined as pH <4, via pH/impedance monitoring
· to assess the safety and tolerability of esomeprazole compared to placebo.

E.3 | Principal inclusion criteria |
1. Patients’ parent/guardian must provide written informed consent prior to the execution of any study-related procedures (according to local regulations).
2. Patients must be either a term or post-term infant beyond the neonatal period but less than 12 months of age, or else be a preterm infant with a corrected gestational age of at least 44 weeks but less than 12 months and weigh between 3 kg and 12 kg, inclusive.
3. Patients must be symptomatic at study entry and have a clinical diagnosis of suspected GERD, symptomatic GERD, or endoscopically proven GERD, made by the investigator and based on the following factors: history, physical examination, symptoms identified during review of systems, laboratory test results, or information from diagnostic testing. Notes in patients’ medical records, along with other source documentation, will be used to support the diagnosis. Patients with erosive esophagitis should be evaluated on a case by case basis to determine eligibility for the treatment withdrawal phase of the study.
4. At least one of the symptoms of GERD must be present for at least twice a week for a 4-week duration in all patients eligible for the study.In addition, these patients, in the opinion of the investigator, have failed a trial of standard anti-reflux measures (thickened feeds, elimination diet, positioning, etc.).
5. Patients with supraesophageal manifestations of GERD, including wheezing, should present with a clinical picture consistent with GERD.
6. Infants with GERD clinical symptoms and suspected food allergy, who in the opinion of the investigator, have not responded to standard medical interventions (e.g. elimination diet) after a reasonable amount of time (e.g. 1-2 weeks).
7. Patients who, in the judgment of the investigator, would be considered for treatment with an acid suppression agent based on symptoms of pathological GER.
8. Patients and parents/guardians must be able to comply with all study procedures.
|
|
E.4 | Principal exclusion criteria |
1. Patients who have used a PPI within 7 days prior to enrollment in the open label treatment phase (Day 0).
2. Patients who have used any prescription or over-the-counter treatment for symptoms of GERD, such as H2RAs or prokinetics, within 24 hours prior to enrollment in the open-label treatment phase (Day 0). Antacids may be used, except for those containing bismuth (e.g., Pepto Bismol® and Kaopectate®).
3. Patients with a history or a current need for resection or reconstructive surgery of the esophagus, stomach, duodenum, or jejunum.
4. Patients with a history of acute life-threatening events (ALTEs), e.g. apnea, near SIDS.
6. Patients with the following active diseases/conditions: gastrointestinal bleed, allergic gastroenteropathies, eosinophilic gastroenteritis bleeding disorders (or a history of these disorders), pyloric stenosis, active seizure disorder, acute pancreatitis, or meningitis.
7. Patients with any acute or chronic illness that, in the opinion of the investigator, would place the patient at risk because of their participation in the study or potentially confound the study data by including the patient.
8. Patients with acute respiratory distress within 72 hours prior to enrollment in the open label treatment phase (Day 0). These patients will be eligible to be re evaluated for inclusion once the acute symptoms have subsided. Patients with a recent RSV infection will be excluded unless they have a documented negative RSV test.
9. Patients with abnormal screening laboratory values, when available, will be
excluded only if the investigator and/or sponsor determine that the abnormalities are
unexplainable or are clinically important and would indicate that the patient would
be at risk from study participation. However, Visit 2 procedures do not have to wait
for Visit 1 laboratory results.
10. Patients with any condition that may require surgery during the course of the study.
11. Patients with a known hypersensitivity, allergy, or intolerance to any component of esomeprazole, omeprazole, or MAALOX or an equivalent age-appropriate non-Bismuth containing liquid antacid.
12. Patients who have used any other investigational compound within 28 days prior to the screening visit.
14. Patients whose parent or guardian refuses to sign the informed consent form or is unable to provide fully informed written consent.
15. Previous enrollment or randomization of treatment in the present study.
