Inclusion criteria
Inclusion criteria: 1. Male and female participants aged 18 years or older at screening (Visit 1) 2. T1DM or T2DM of at least 5 years’ duration, with controlled and stable blood glucose levels (ie, no episodes of diabetic ketoacidosis, Hyperosmolar Hyperglycemic Nonketotic Diabetic Syndrome, or severe hypoglycemia within the 6 months preceding screening [Visit 1]) 3. HbA1c =11.0% at screening (Visit 1) in participants being treated with oral and/or parenteral medications for T1DM or T2DM with the goal of achieving controlled and stable glucose levels 4. DG defined as at least a 3-month history prior to screening (Visit 1) of symptoms on an ongoing basis that are suggestive of GP (eg, nausea, abdominal pain, post-prandial fullness, bloating, vomiting, and early satiety) 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 endoscopy or other equivalent diagnostic test, performed at some time before screening (Visit 1) 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) 9. BMI > 18.5 kg/m2 10. Able to provide written informed consent (IC) prior to any study procedures and willing and able to comply with study procedures Additional inclusion criteria for randomization after the 2-week, placebo Run-in Period: 11. Compliance with the entry of data into the hand-held electronic device on at least 10 of 14 days during the placebo Run-in Period 12. Compliance with administration of SC twice daily injections, as evidenced by entries made by the participant using the electronic, hand-held device on at least 10 of 14 days during the placebo Run-in Period 13. At least one vomiting episode at any time during the placebo Run-in Period, as recorded in the DGSSD, using the electronic hand-held device 14. The average of the daily DGSSS from the 2-week, placebo Run-in Period must be = 16 Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 1500 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 500
Exclusion criteria
Exclusion criteria: 1. Symptomatic Irritable Bowel Syndrome at Screening (Visit 1) 2. Small intestinal bacterial overgrowth (SIBO) at Screening (Visit 1) 3. History of anorexia nervosa, binge-eating, bulimia, or other eating disorder within 5 years of screening (Visit 1) 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), or other drugs considered to be GI pro-motility 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 significance of a positive 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, therefore, 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 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 23. 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
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: - To compare the efficacy of relamorelin with placebo in participants with DG with respect to a composite of the following core signs and symptoms of DG: Nausea, Abdominal pain, Postprandial fullness, Bloating - To compare the efficacy of relamorelin with placebo in participants with DG with respect to vomiting frequency ;Secondary Objective: - To compare the efficacy of relamorelin with placebo in participants with DG with respect to the following individual symptoms of the DGSSS: Nausea, Abdominal Pain, Postprandial fullness, Bloating - To compare the safety of relamorelin with placebo in participants with DG ;Primary end point(s): - The Diabetic Gastroparesis Symptom Severity Score (DGSSS) Responder, defined as a participant who has a = 10-point improvement in the DGSSS compared to baseline in each of the last 6 weeks of the 12-week Treatment Period - Vomiting Responder, defined as a participant who reports no vomiting episodes during each of the last 6 weeks of the 12-week Treatment Period ;Timepoint(s) of evaluation of this end point: each of the last 6 weeks of the 12-week Treatment Period | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Individual Symptom (ie, nausea, abdominal pain, postprandial fullness, and bloating) Responder, defined as a participant with at least a 2-point decrease in the change from baseline on the weekly average of the symptom severity (at its worst) during each of the last 6 weeks of the 12-week Treatment Period - AEs, clinical laboratory values, vital signs, ECGs, HbA1c, and anti-relamorelin antibodies ;Timepoint(s) of evaluation of this end point: each of the last 6 weeks of the 12-week Treatment Period | — |
