Recruitment

|||||||||||||||||||||||||
Recruitment details |
Participants took part in the study at 18 investigative sites in Mexico, Poland, Portugal and the United States from 22 June 2012 (first participant to sign the informed consent) to 10 November 2014. | ||||||||||||||||||||||||
Pre-assignment
|
|||||||||||||||||||||||||
Screening details |
63 adolescents with a diagnosis of erosive esophagitis (EE) were enrolled in the dexlansoprazole delayed release 60 mg capsules open label phase. One participant did not take study drug. Participants with healed EE were randomized into one of 2 treatment groups: dexlansoprazole delayed release 30 mg capsules or placebo in the maintenance phase | ||||||||||||||||||||||||

Notes [1] - The number of subjects reported to have started the pre-assignment period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same. Justification: 1 participant did not receive study medication and therefore was not accounted for in the worldwide number enrolled. |

Notes [2] - The number of subjects starting the period is not consistent with the number completing the preceding period.

End point description |
An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (eg, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A Treatment Emergent Adverse Event (TEAE) is defined as an Adverse Event (AE) that starts or worsens on or after Study Day 1, and no more than 30 days after the last dose.

1. In order to decrease the number of required biopsies and to allow flexibility for standard of care, the duodenal biopsies were removed and a serologic test was specified for use to screen for celiac disease.
2. To ensure compliance with local ethical and regulatory requirements, P450 CYP2C19 genotype testing was not required when local regulations prohibited it. Storage and use of samples were also clarified.
|
||
25 Apr 2013 |
1. In order to allow for a pre-screening endoscopy to be used for eligibility if all other protocol requirements were met, an allowance was made for the screening endoscopy to have been performed within 1 week prior to signing the informed consent/assent form.
2. In order to add flexibility for the time allowed for screening, a window of 5 days was added to the Screening Period.
3. The number of biopsies required at Screening was reduced in order to increase flexibility and to be aligned with standard of care for biopsy collection.
4. H. pylori test procedures were clarified, particularly for instances in which pre-screening endoscopy results were used to determine eligibility.
5. Exclusion criterion was updated regarding HIV status.
6. Exclusion criterion regarding alcohol use was updated to account for regional differences.
7. Inclusion and exclusion criterion were updated to account for allowance of endoscopies done prior to Screening and other H. pylori test methods.
8. Alternate dosing options were added to accommodate children who could not swallow the capsule. |
