  3. Must have an average composite ANMS GCSI-DD symptom score 2 during the 7 days before randomization. The predominant symptom experienced by participants must not be abdominal pain.
  4. Must experience nausea: nausea subscale (of ANMS GCSI-DD) symptom score 2 at least 4 of 7 days or an average nausea subscale symptom score 2 during the 7 days before randomization.

  5. History of intra-pyloric botulinum toxin injection within 3 months of Screening or currently has functioning implantable electric stimulator.
  6. Nasogastric, percutaneous endoscopic gastrostomy, or percutaneous endoscopic jejunostomy feeding tube or inpatient hospitalization for gastroparesis within 2 weeks before the Screening Visit.
  7. Required parenteral nutrition for treatment of gastroparesis within 2 months before the Screening Visit.
  8. Previous diagnosis of gastric bezoar (the presence of retained liquid, bile, or small amounts of poorly organized food residue is permitted).
  9. Poor control of diabetes within 30 days prior to randomization, including diabetic ketoacidosis, hypoglycemia requiring medical intervention, admission for control of diabetes or diabetic complications
  10. Elevated serum prolactin (>upper limit of normal [ULN]) at Screening Visit 2.
