An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (e.g., a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A treatment-emergent adverse event (TEAE) is defined as an adverse event with an onset that occurs after receiving study drug. A SAE is an AE resulting in any of the following outcomes or deemed significant for any following reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; or congenital anomaly; or a medically important event.

Clinical Laboratory parameters included tests for chemistry, hematology and urinalysis. Markedly abnormal values during treatment period were categorized as:alanine aminotransferase (ALT)\>3.0 U/L\*upper limit of normal(ULN),albumin\<25 g/L\*lower limit of normal(LLN),alkaline phosphatase \>3.0 U/L\*ULN,aspartate aminotransferase \>3.0 U/L\*ULN,bilirubin \>2 umol/L\*ULN,blood urea nitrogen(BUN) \>10.7 mmol/L,calcium \<1.75 mmol/L, \>2.88 mmol/L,chloride \<75 mmol/L, \>126 mmol/L,creatinine \>177umol/L,gamma glutamyl transferase (GGT) \>3 U/L\*ULN,glucose \<2.8 mmol/L, \>19.4 mmol/L,phosphate \<0.52 mmol/L, \>2.10 mmol/L,potassium\<3 mmol/L, \>6 mmol/L,sodium \<130 mmol/L, \>150 mmol/L,hematocrit (%) \<0.8\*LLN, \>1.2\*ULN,hemoglobin \<0.8 g/L\*LLN, \>1.2 g/L\*ULN,leukocytes \<0.5 (10\^9/L)\*LLN, \>1.5 (10\^9/L)\*ULN,erythrocytes\<0.8 (10\^12/L)\*LLN, \>1.2(10\^12/L)\*ULN,platelets \<75(10\^9/L), \>600(10\^9/L). Participants with at least 1 markedly abnormal laboratory parameter value is reported.

Vital signs included body temperature, diastolic and systolic blood pressure (mmHg), and heart rate (beats per minute \[bpm\]). Heart rate\<50 bpm and systolic blood pressure \<85 mmHg were considered markedly abnormal.

The 12-lead electrocardiogram (ECG) values outside the range Heart Rate \<50 (beats/min), PR Interval ≤120 (msec), PR Interval ≥200 (msec), QRS Duration ≥120 (msec), QT Interval ≥460 (msec) were considered markedly abnormal.

ANMS GCSI-DD is a patient-reported outcome instrument for a symptom-based clinical trial endpoint in gastroparesis. The ANMS GCSI-DD composite score included score of nausea, early satiety, upper abdominal pain, and postprandial fullness. The severity scores of these symptoms range from 0 (none) to 4 (very severe). The daily composite score was calculated by summing the scores on the 4 symptom items (nausea, early satiety, postprandial fullness, and upper abdominal pain) and then dividing by 4, that is the number of items within the composite score. Thus, the maximum daily composite score was (4 symptoms × maximum score 4 divided by 4) = 16/4 = 4. The ANMS GCSI-DD daily composite score ranged from 0 to 4 with higher scores reflecting greater symptom severity. The negative change from baseline indicates improvement. Mixed-effects Model for Repeated Measures (MMRM) was used for the analysis.
