The percentage of days with neither daytime nor nighttime heartburn was equal to (=) (the days that were heartburn-free during the treatment period) / (total number of days for which either a daytime or nighttime result was marked during treatment period)\*100 percent (%).

Well-controlled participants were defined to be participants who completed the study having at least 23 days of evaluable diary entries between Days 15 and 42, inclusive, and had ≤4 occurrences of heartburn during this period.

Percentage calculated by the number of heartburn-free nights out of the total number of nights during the treatment period with a diary entry indicating presence or absence of nighttime heartburn in subjects who had ≥1 diary entry indicating presence or absence of nighttime heartburn, as indicated by the subject's daily diary. Subjects indicate the presence (Yes/No) of nocturnal heartburn symptoms in a Daily Electronic Diary. Nights missing diary results were excluded from the numerator and denominator.

The percentage was calculated as the days that were heartburn-free out of the total number of days for which either a daytime or nighttime result was marked.

Crude rates analyzed maintenance of healed EE from baseline of this study and considered prematurely discontinued subjects as relapsed.

Percentage of subjects who maintained complete healing of erosive esophagitis as assessed by endoscopy. In the life table method, subjects without post-baseline endoscopy were included as censored; subjects who did not have a recurrence of EE and did not complete the study were also considered censored.

Hematocrit measurement percent is the absolute difference in Hematocrit values, and not percentage difference.

Normal=normal tissue; Unknown Baseline = Baseline biopsy not available; Abnormal diagnoses include: Reactive Gastropathy, Chronic Gastritis, Intestinal Metaplasia, Reflective Observation Mucosa-Associated Lymphoid Tissue Lymphoma, Other Abnormal.

Percentage of subjects with complete healing of EE as assessed by endoscopy was analyzed for change in LA Esophagitis Classification grades A, B, C, or D to healed. Healed is defined as anything that is less than the criterion for Grade A (greater than or equal to 1 mucosal break and less than 5 mm). If it doesn't meet the A criterion, it's counted as healed.

Daily electronic diaries (eDiaries) will be completed which contain Pediatric Gastroesophageal Reflux Disease Symptom Daily Diaries (PGSDD) questionnaires that document presence or absence of hurting or burning in the stomach, chest or throat vomiting, regurgitation and trouble eating. Parents or caregivers of participants aged 2 to 8 years will complete the PGSDD (parent) in the eDiary for their child and participants aged 9 to 11 years will complete PGSDD (child) in the eDiary themselves. The eDiaries will be completed on a daily basis reflecting a continuous 24-hour period.

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.

A Treatment Emergent Adverse Event (TEAE) is defined as an Adverse Event (AE) that started or worsened on or after Study Day 1 (defined as first dose day), and no more than 30 days after the last dose of study drug.

The disintegration time is the total time from when the participant places the tablet on their tongue until the time at which the participant would normally swallow the remaining materials from the disintegrated tablet. The average disintegration time will be calculated for each participant based on 3 separate tests.

Maximum observed plasma concentration (Cmax) is the peak plasma concentration of a drug after administration, obtained directly from the plasma concentration-time curve.

Maximum observed plasma concentration (Cmax) is the peak plasma concentration of a drug after administration, obtained directly from the plasma concentration-time curve.

AUC(0-tlqc) is a measure of total plasma exposure to a drug from time 0 to time of the last quantifiable concentration.

AUC(0-tlqc) is a measure of total plasma exposure to a drug from time 0 to time of the last quantifiable concentration.

AUC(0-inf) is a measure of the area under the plasma concentration-time curve from time 0 extrapolated to infinity.

AUC(0-tau) is a measure of the area under the plasma concentration-time curve from time 0 to time tau over a dosing interval, where tau is the length of the dosing interval (24 hours).

The percent change in bone formation marker P1NP measured at week 26 from P1NP measured at baseline. Serum samples for P1NP were analyzed at a central laboratory for bone biomarker P1NP using an electrochemiluminescence immunoassay measured in nanograms per milliliter (ng/mL).
