Primary Outcome Measures:
  • Pharmacodynamic (PD) effects of RM-131 on gastric emptying [ Time Frame: Day 1 at baseline vs Day 1 at 6 hours after dosing in Period 1 and Day 1 at baseline vs Day 1 at 6 hours after dosing in Period 2 ] [ Designated as safety issue: No ]
    Change from baseline in gastric half-emptying time by scintigraphy (solids and liquids)

Secondary Outcome Measures:
  • Safety and tolerability of RM-131 [ Time Frame: Day 1 and 2 after dosing in Period 1 and Day 1 and 2 after dosing in Period 2 ] [ Designated as safety issue: Yes ]
    Number of participants with adverse events

  • Pharmacokinetics (PK) of RM-131 [ Time Frame: Day 1 at baseline vs Day 1 at 6 hours after dosing in Period 1 and Day 1 at baseline vs Day 1 at 6 hours after dosing in Period 2 ] [ Designated as safety issue: No ]
    Median T-max of RM-131 levels in patients with type 2 diabetes mellitus

Ages Eligible for Study:   18 Years to 60 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Key Inclusion Criteria:

  • Able to provide written informed consent prior to any study procedures.
  • Diagnosis of Type 1 or 2 diabetic gastroparesis.
  • Controlled Type 1 or 2 diabetes mellitus (HbA1c <10.1%).
  • Stable concomitant medications defined as no changes in regimen for at least 2 weeks prior to Period 1 (daily adjustments of insulin doses are permitted).
  • Body mass index of 18-40 kg/m².

Key Exclusion Criteria:

  • Unable or unwilling to provide informed consent or to comply with study procedures.
  • History of gastric surgery such as fundoplication, gastrectomy, gastric pacemaker placement, vagotomy, bariatric procedure. (Note: history of diagnostic endoscopy is not exclusionary).
  • Acute or chronic illness or history of illness, which in the opinion of the Investigator, could pose a threat or harm to the patient or obscure interpretation of laboratory test results or interpretation of study data such as frequent angina, Class III or IV congestive heart failure, poor renal or hepatic function, etc.
  • Any clinically significant abnormalities on screening laboratories as determined by the Investigator.
  • Abnormal 12-lead electrocardiogram (ECG), including evidence of acute myocardial or subendocardial ischemia and clinically significant arrhythmias or conduction abnormalities or blood pressure at screening except minor deviations deemed to be of no clinical significance by the Investigator.
  • Poor venous access or inability to tolerate venipuncture.
  • Acute GI illness within 48 hours of Period 1.
  • Positive pregnancy test.
  • Participation in a clinical study within the 30 days prior to dosing in the present study.
  • Any other reason, which in the opinion of the Investigator, would confound proper interpretation of the study.
