Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
||A Phase 2 Multicenter, 36-Week Study to Assess the Safety and Effectiveness of Daily Oral Administration of Dexlansoprazole Delayed-Release Capsules for Healing of Erosive Esophagitis and Maintenance of Healed Erosive Esophagitis and Relief of Heartburn, in Adolescent Subjects Aged 12 to 17 Years
Primary Outcome Measures:
- Percent of Participants who Experience Each Treatment Emergent Adverse Event experienced by ≥5% of participants during the 8-week Healing Treatment Period [ Time Frame: 8 weeks ] [ Designated as safety issue: Yes ]
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.
- Percent of Participants who Experience Each Treatment Emergent Adverse Event experienced by ≥5% of participants during the 16-week maintenance Treatment Period [ Time Frame: From Week 8 to Week 24 ] [ Designated as safety issue: Yes ]
A TEAE is defined as an AE that starts or worsens on or after Study Day 1, and no more than 30 days after the last dose.
Secondary Outcome Measures:
- The percentage of participants with healing of EE by Week 8 [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
Healing of EE will be assessed by endoscopy.
- The percentage of participants who maintain healing of EE from Week 8 to Week 24 [ Time Frame: From Week 8 to Week 24 ] [ Designated as safety issue: No ]
The percentage of participants who maintain healing of EE from Week 8 to Week 24 among the patients who were healed at Week 8 as assessed by endoscopy.
- The percentage of days with neither daytime nor nighttime heartburn over the first 8 weeks of treatment [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
The percentage of days with neither daytime nor nighttime heartburn over the first 8 weeks of treatment as assessed by electronic daily diary.
- The percentage of days with neither daytime nor nighttime heartburn over Weeks 8 to 24 [ Time Frame: Weeks 8 to 24 ] [ Designated as safety issue: No ]
The percentage of days with neither daytime nor nighttime heartburn over Weeks 8 to 24 as assessed by electronic daily diary among the participants who were healed at Week 8.

|Ages Eligible for Study:
||12 Years to 17 Years
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
- In the opinion of the investigator, the participant and parent(s) or legal guardian are capable of understanding and complying with protocol requirements.

- The participant has a medical history of symptoms of GERD for at least 3 months prior to Screening (signed informed consent form and assent, if applicable) as assessed by the investigator.
- The participant has met the electronic diary qualification criteria as assessed by the electronic daily diary defined as follows: heartburn (burning or hurting in your throat, chest, or stomach) on at least 3 of 7 days.(Note: if an endoscopy done within 1 week of signing informed consent and assent is used to confirm diagnosis of EE, the subject does not need to meet this criterion).
- The participant has endoscopic evidence of EE (LA Grade A-D) based on the screening endoscopy.
- The participant is male or female and aged 12 to 17 years, inclusive.
