Study Type: Interventional
Official Title: Protocol PT 11-29: Randomized, Open-label, Cross-over Pilot Study to Evaluate and Compare Two Omeprazole Containing Products for Relief of Frequent Heartburn

Detailed Summary:
Sponsor: Bayer
Current Primary Outcome: Time-to-onset of Heartburn Relief [ Time Frame: Start of treatment until onset of heartburn relief, up to 24 hours ]
Time-to-onset of heartburn relief was defined as earliest time following start of treatment that participant experienced a reduction of at least one grade from baseline in the severity of heartburn. Severity of heartburn was evaluated by the participant using the 4-point Likert Scale, which rated heartburn severity as follows:
Absent (0): Heartburn is not present.
Mild (1): Heartburn did not last long or was easily tolerated.
Moderate (2): Heartburn caused discomfort and interrupted usual activities.
Severe (3): Heartburn caused great interference with usual activities and may have been incapacitating.
Original Primary Outcome: Time-to-onset of Heartburn Relief [ Time Frame: Up to 24 hours following the first dose of study drug ]
Current Secondary Outcome:
- Percentage of Participants Experiencing Onset and Demonstrating Duration of Heartburn Relief Over Time [ Time Frame: Start of treatment until onset of heartburn relief, up to 72 hours ]
Onset of heartburn relief was defined as a reduction of at least one grade from baseline in the severity of heartburn following start of treatment. Severity of heartburn was evaluated by the participant using the 4-point Likert Scale, which rated heartburn severity as follows:
Absent (0): Heartburn is not present.
Mild (1): Heartburn did not last long or was easily tolerated.
Moderate (2): Heartburn caused discomfort and interrupted usual activities.
Severe (3): Heartburn caused great interference with usual activities and may have been incapacitating.
- Number of Participants Preferring Each Treatment for Heartburn Control: Final Subjective Questionnaire [ Time Frame: At end of study (approx. Study Day 40) ]Participants completed a Final Subjective Questionnaire for Treatment Preference. Question 1 asked participants to compare the 2 treatments for Heartburn Control.
- Number of Participants Preferring Each Treatment for Heartburn Relief: Final Subjective Questionnaire [ Time Frame: At end of study (approx. Study Day 40) ]Participants completed a Final Subjective Questionnaire for Treatment Preference. Question 2 asked participants to compare the 2 treatments for Heartburn Relief.
- Number of Participants Preferring Each Treatment Overall: Final Subjective Questionnaire [ Time Frame: At end of study (approx. Study Day 40) ]Participants completed a Final Subjective Questionnaire for Treatment Preference. Question 3 asked participants to compare the 2 treatments for their overall preference.
- Percentage of Participants Affected By Heartburn Symptoms: End of Treatment Quality of Life Questionnaire [ Time Frame: End of treatment period 1 and end of treatment period 2 ]End of Treatment Quality of Life was based on a questionnaire regarding quality-of-life issues associated with heartburn, completed by participants at the end of treatment period 1 and the end of treatment period 2.
Original Secondary Outcome:
- Duration of Heartburn Relief [ Time Frame: Up to 4 days of study drug use ]
- Subjective Study Drug Preference [ Time Frame: End of Study, up to 114 days ]Subjective study drug preference will be assessed by using data from the questionnaires administered during the study. Participants will answer a series of questions about their heartburn relief and treatment preference.
