|
Secondary Endpoint (Open-label, 12 Months on Stimulation): GERD-HRQL Score (Off-PPI/H2 Blocker)
Tidsramme: 12 months on stimulation
|
The secondary efficacy endpoint was the number of subjects achieving GERD symptom success defined as an improvement in the composite GERD Health-related Quality of Life (GERD-HRQL) patient reported outcome questionnaire score of 50% or more after 12 months on stimulation compared to the baseline off-PPI or H2 blocker composite GERD-HRQL score.
Questions regarding heartburn severity and difficulty swallowing are asked on scale of 0 to 5: 0 = No symptoms; 1 = Symptoms noticeable but not bothersome; 2 = Symptoms noticeable and bothersome but not every day; 3 = Symptoms bothersome every day; 4 = Symptoms affect daily activities; and 5 = Symptoms are incapacitating - unable to do activities.
The composite score is calculated by adding the responses to the individual questions.
The minimum score possible is 0 and the maximum score is 45.

Secondary Endpoint (Open-label, 12 Months on Stimulation): GERD-HRQL On-PPI
Tidsramme: 12 months on stimulation

Composite GERD Health-related Quality of Life (GERD-HRQL) patient reported outcome questionnaire scores.
Questions regarding are asked on scale of 0 to 5: 0 = No symptoms; 1 = Symptoms noticeable but not bothersome; 2 = Symptoms noticeable and bothersome but not every day; 3 = Symptoms bothersome every day; 4 = Symptoms affect daily activities; and 5 = Symptoms are incapacitating - unable to do activities.
The composite score is calculated by adding the responses to the individual questions.
The minimum score possible is 0 and the maximum score is 45.
Previous versions of the protocol and case report forms did not include the question about bloating; thus, this question was not included in the calculation of the composite score.
The lower scores are associated with less impactful symptoms.
