5. Female participants willing to minimize the risk of inducing pregnancy for the duration of the clinical study and follow-up period
A female participant is eligible to participate if she is not pregnant (has a negative urine pregnancy result prior to randomization), not breastfeeding, and at least one of the following conditions applies:
a. Not a woman of childbearing potential (WOCBP)
OR
b. A WOCBP who agrees to follow the contraceptive guidance during the treatment period and for at least 7 days after the last dose of study treatment
6. Documentation of absence of an obstructing lesion on upper GI series with contrast or upper endoscopy, performed at some time before the Run-in period (Visit2), but after the appearance of symptoms that led to the diagnosis of DG
7. At least 2 vomiting episodes during the 2 weeks prior to screening (Visit 1), as ascertained by participant history
8. Delayed GE confirmed by abnormal GEBT, defined as GE half-time (t½) ≥ 79 minutes at the start of the placebo-controlled Run-in Period (Visit 2). In countries where the GEBT is not available, delayed GE may be confirmed by abnormal scintigraphy result (> 60% retention at 2 hours or > 10% at 4 hours). Refer to the Study Reference Manual
9. The BMI criterion has been removed.
10. Able to provide written informed consent (IC) prior to any study procedures and willing and able to comply with study procedures

E.4 | Principal exclusion criteria |
1. Symptomatic Irritable Bowel Syndrome at Screening (Visit 1)
2. Small intestinal bacterial overgrowth (SIBO) at Screening (Visit 1)
3. Participants who are actively experiencing anorexia nervosa, binge-eating, bulimia, or other eating disorder at the time of screening (Visit 1) are excluded regardless of when diagnosis was established.
4. History of intestinal malabsorption (including celiac disease even if well-controlled on a gluten-free diet) or pancreatic exocrine insufficiency; also, history of non-celiac gluten sensitivity
5. History of belching disorders, other nausea and vomiting disorders (eg, chronic nausea and vomiting syndrome, cyclic vomiting syndrome, cannabinoid hyperemesis syndrome), or rumination syndrome
6. History of chronic obstructive pulmonary disease or other causes of pulmonary
dysfunction that have resulted in CO2 retention
7. Gastric or duodenal ulcer within 3 months of Screening (Visit 1)
8. Evidence of hepatic disease defined as alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≥ 3 x ULN, and/or direct bilirubin ≥ 2 x ULN
9. History of malignancy in the 3 years prior to Visit 1, except for adequately treated basal cell or squamous cell skin cancer, or in situ cervical cancer
10. Currently receiving parenteral feeding or presence of a nasogastric or other enteral tube for feeding or decompression
11. Use of metoclopramide, domperidone, prucalopride, macrolide antibiotics (eg, erythromycin, clarithromycin, azithromycin), 5HT4 agonists (cisapride, tegaserod, and prucalopride) or other drugs considered to be GI promotility agents for at least 10 days prior to the start of the Run-in Period (Visit 2)
12. Positive results on the urine drug screen at Screening (Visit 1). The sponsor may permit a participant with a positive urine drug screen (UDS) by immunoassay at Screening to continue in screening while confirmatory testing by a more specific method is carried out on an aliquot of the original urine sample. If the confirmatory test is negative,
the initial positive UDS will be considered to have been a false-positive urine drug screen and the participant can continue in screening. Confirmatory testing will be done at the discretion of the sponsor and must be approved by the sponsor prior to analysis. The significance of a positive urine drug screen result for drugs prescribed for the participant (e.g., barbiturates, benzodiazepines, amphetamines, but not cannabinoids) should be assessed by the Investigator as to whether their stable-dose usage is clinically appropriate, and, if so, should not be exclusionary; use of these drugs on an as-needed basis is not allowed.
13. Currently taking opioids, or expecting to use opioids during the course of the clinical study.
14. Treatment with glucagon-like peptide-1(GLP-1) agonist for at least 6 weeks prior to the start of the Run-in Period (Visit 2)
15. History of pyloric injection of botulinum toxin within 6 months of screening
16. History of gastric surgery such as fundoplication, gastrectomy, gastric pacemaker placement, vagotomy, or bariatric procedure (a history of diagnostic endoscopy is not exclusionary)
17. Randomization in any previous study in which relamorelin was a treatment
18. Estimated glomerular filtration rate (eGFR) of < 30 mL/min
19. Current enrollment in an investigational drug or device study or participation in such a study within 30 days of entry into this study
20. Allergic to, or intolerant of egg, wheat, milk, or algae, as these are components of the GEBT study meal
21. Females who are pregnant, nursing, or planning a pregnancy during the study. For females who are of childbearing potential, see Appendix 5
22. The participant has a condition or is in a situation which, in the investigator’s opinion, may put the participant at significant risk, may confound the study results, or may interfere significantly with the participant’s participation in the study

Participant is directly or indirectly involved in the conduct and administration of this study as an investigator, subinvestigator, study coordinator, other study staff member, or employee of Allergan, Inc.; or the participant is a first-degree family member, significant other, or relative residing with one of the above persons involved directly or indirectly in the study; or the participant is enrolled in this study at another clinical study site
24. Functional dyspepsia diagnosed before the diagnosis of diabetes mellitus
25. Hypersensitivity to the study treatments and their excipients (ie, mannitol or phenol)
