Trial Outcomes & Findings for Impact of KUVAN® on Gastric Relaxation in Women With Diabetic Gastroparesis. (NCT NCT01135186)

9 women with moderate to severe gastroparesis were enrolled at medical clinic.

Impact of KUVAN® on Gastric Relaxation in Women With Diabetic Gastroparesis.

Gastric Accommodation refers to the reflexive relaxation of the upper stomach after swallowing as measured by the Satiety Test at baseline, 4 weeks, and 8 weeks. Increased gastric accommodation is considered a positive outcome.

Change in symptom severity over the past 2 weeks as measured by the patient reported Gastroparesis Cardinal Symptom Index (GCSI) The GCSI is composed of 9 questions. Each question asks about symptom severity on a scale of 1-5 listed below. 0=None 1= Very mild 2= Mild 3=Moderate 4=Severe 5= Very severe The 9 scores are summed together for cumulative GCSI score. The minimum cumulative score is '"0" and the maximum cumulative score is "45." Once we calculated the cumulative score for each participant, we took the average of all participants cumulative scores giving us the sample mean. This was done at baseline, week 4, and week 8. Higher total scores indicate higher symptom severity. Lower total scores indicate lower symptom severity.

Quality of life as impacted by patients with upper gastrointestinal disorders (PAGI-QOL) The PAGI-QOl is composed of 30 questions. Each question asks about the degree to which a patient's quality of life is impacted by upper gastrointestinal disorders. Questions measure quality of life impact on a scale of 1-5 listed below. 0=none of the time, 1=a little of the time, 2=some of the time, 3=a good bit of the time, 4= most of the time, 5= all of time The 30 items are summed together for a cumulative PAGI-QOL score. The minimum cumulative score is "0" and the maximum score is "150." Once we calculated the cumulative score for each participant, we took the average of all participants cumulative scores giving us the sample mean. This was done at baseline, week 4, and week 8. Lower scores indicate an improved overall quality of life. Higher scores indicate a diminished overall quality of life.

Symptom severity as measured by the Patient Assessment of Upper Gastrointestinal Disorder- Symptom Severity Index. (PAGI-SYM) The PAGI-SYM is compose of 20 questions. Each question can be answered on a scale of 1-5 (below) 0 = none, 1=very mild, 2=mild, 3=moderate, 4=severe, 5=very severe Cumulative scores were calculated by summing all 20 questions. The minimum cumulative scores would be "0" while the maximum cumulative score would be "100" Once we calculated the cumulative score for each participant, we took the average of all the cumulative scores giving us the sample mean. This was done at baseline, week 4, and week 8. Lower score indicates decreased symptom severity. Higher score indicates increased symptom severity.
