Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from baseline in daily average nausea severity scores from the Gastroparesis Core Symptom Daily Diary (GCS-DD)	A daily symptom diary asking patients to rate their nausea on a Likert scale from 0-5 (0=none, 5= very severe).	12 weeks
Secondary	Change from baseline in other average core gastroparesis symptoms from the Gastroparesis Core Symptom Daily Diary	A patient reported daily symptom diary asking patients to rate their nausea on a Likert scale from 0-5 (0=none, 5= very severe). Other symptoms include vomiting, postprandial fullness, early satiety, and abdominal pain	12 weeks
Secondary	Change from baseline in Patient Assessment of Gastrointestinal Disorders - Symptoms Severity Index (PAGI-SYM)	PAGI-SYM is a patient reported outcome that measures specific symptoms of patients with upper gastrointestinal disorders such as gastroparesis, GERD, and dyspepsia on a 0-5 Likert Scale (0=none, 5=very severe).	12 weeks
Secondary	Change from baseline in Patient Global Impression - Change (PGI-C)	A patient reported outcome measuring a patient's rating of overall improvement after treatment on a 7 point scale that includes items "1=very much worse" and "7=very much improved"	12 weeks
Secondary	Clinician Global Impression - Severity (CGI-S)	A clinician reported outcome that measures the clinician's view of the patient's global functioning prior to and after initiating treatment. Symptom severity is measured on a 7 point scale including "1=normal, not at all ill" and "7=among the most extremely ill patients."	12 weeks
Secondary	Safety and tolerability as measured by spontaneous reporting of adverse events (AEs)	Safety will be monitored using clinical measures, vital signs, blood chemistry, hematology, urology, ECGs, and patient reported questionnaires.	12 weeks
