General information about the trial
|
|||
Main objective of the trial |
The primary objective of this study was to assess the difference between esomeprazole and placebo in the treatment of signs and symptoms of GERD as observed by 8-hour video and cardiorespiratory monitoring in neonatal patients.
|
||
Protection of trial subjects |
There was no data monitoring board; however a Data and Safety Monitoring Plan was available for this study. The Clinical Study Physician monitored the SAEs on a continuous basis. A Drug Safety Physician reviewed all serious unexpected reports that were assessed by the investigator to be causally related to study drug within 15 days from AstraZeneca notification of the event. In addition, a safety subteam, consisting of the AstraZeneca Drug Safety Physician(s), Drug Safety Scientist, Clinical Study Physician, Study Delivery, and other Clinical Study Team members met on a regular basis to review blinded study data regarding SAEs, non-serious AEs, discontinuation criteria, clinically significant laboratory data, and vital signs. The safety subteam could request additional evaluations at their discretion from the study center.

Notes [1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same. Justification: 61 patients were screened, 52 randomized (=>6 were incorrect enrolled, 2 voluntary discontinuation by parent/guardian, 1 other reason). The baseline numbers reflect the randomized patients. |
