Change From Baseline to Week 12 in the Biweekly Average of Daily Nausea Severity Score Using MMRM Model ITT Population
大体时间:12 weeks
|
The Gastroparesis Core Symptom Daily Diary (GCSDD) is a patient reported diary that asks patients to rate the worst occurrence of each cardinal symptom of gastroparesis (nausea severity, early satiety, postprandial fullness, bloating, and abdominal pain) in the past 24 hours on a Likert scale from 0 (no symptoms) to 5 (very severe). Change from baseline in average nausea severity score is calculated as the biweekly average post value minus baseline value of the daily nausea severity score from the GCSDD. A negative change indicates improvement. |

Change From Baseline in Gastroparesis Cardinal Symptom Index (GCSI) Total Score Using MMRM Model ITT Population
大体时间:12 Weeks
|
The GCSI is a subject reported outcome administered in-clinic with a 2-week recall period to measure the severity of symptoms in gastroparesis. The GCSI is composed of 9 items based on three subscales: post-prandial fullness/early satiety (4 items); nausea/vomiting (3 items), and bloating (2 items). The severity of each symptom is rated on a six-point Likert response scale. The minimal scale value = 0 (none) and the maximum scale value = 5 (very severe). GCSI Total score is constructed as the average of the three symptom sub-scales. Higher score is indicative of greater symptom severity. |

Change From Baseline to Week 12 in the Biweekly Percentage of Nausea Free Days Using MMRM Model ITT Population
大体时间:12 Weeks
|
The Gastroparesis Core Symptom Daily Diary (GCSDD) is a patient reported diary that asks patients if they have had any nausea over the past 24 hours and if yes, to rate the worst occurrence in the past 24 hours on a Likert scale from 1 (very mild) to 5 (very severe). Change in weekly percentage of nausea-free days from baseline is calculated as biweekly average post value minus baseline value. |
12 Weeks
|
|
Change From Baseline in Overall Patient Benefit Scale (OPBS) ITT Population
大体时间:12 Weeks
|
The Overall Patient Benefit Scale (OPBS) is a weighted average of the recoded symptom improvement score of the five PRCGS items. The PRCGS data are recoded as follows: 3 - very much improved, 2 - much improved, 1 - minimally improved, 0 - no change or worse. The OPBS ranges from 0 to 3, with higher values indicating a better outcome. |
