The NIDDK Gastroparesis Registry 3: Characterization and Clinical Course of Symptoms and Gastric Emptying in Patients With Symptoms of Gastroparesis

The purpose of this study is to create a new registry of patients with gastroparesis in order
to better understand the characteristics of patients with gastroparesis and follow how their
condition changes over time. The data collected may improve the understanding of the
condition to enable better diagnosis and treatment.

GpR 3 is an observational study of patients with symptoms of gastroparesis with either
delayed or normal gastric emptying. Epidemiological, clinical, physiological, and patient
outcome data will be collected to characterize the patients and their clinical course to
better understand this disorder. The long-term goal is to help phenotype patients into
pathophysiologically defined subsets. This classification will provide a foundation for
translational research, facilitating the search for etiopathogenesis and enhance the ability
to define and conduct large clinical trials, ultimately leading to the development of more
rational and effective therapeutic approaches for gastroparesis.

The primary objectives of the Gastroparesis Registry 3 (GpR 3) are:

- To create a new registry of patients with symptoms of gastroparesis, both patients with
delayed gastric emptying and patients with similar symptoms but normal gastric emptying,
for the enhanced study of symptoms, gastric motility abnormalities, patient
characteristics, and degree of morbidity.

- To follow a well-characterized cohort to further define the natural history and clinical
course of patients with symptoms of gastroparesis - both symptoms and gastric emptying
over time. Treatments given for their clinical care and clinical responses to treatments
will be recorded.

- To provide a reliable source for recruitment of well-characterized patients with
gastroparesis for other studies including therapeutic clinical trials,
pathophysiological, molecular, histopathologic, or other ancillary studies. These
subsequent clinical trials or ancillary studies will be conducted under separate study
protocols with separate consent processes.

Specific secondary objectives of GpR3 have been developed to allow the patients entered in
GpR3 to help advance our understanding of gastroparesis:

- Assess several areas of gastric motility in patients with symptoms of gastroparesis
(fundic accommodation, antral contractility, global gastric emptying).

- Determine the change in gastric motility over time, in patients with gastroparesis and
in patients with symptoms of gastroparesis but normal gastric emptying.

- Evaluate the clinical symptomatic course (outcome) of patients followed in the registry.

- Use the registry to better capture clinical treatment responses to specific treatments
while patients are in the registry.

- Characterize abdominal pain in patients with gastroparesis and gastroparesis-like
syndrome by:

- Describing the abdominal pain seen in patients with gastroparesis

- Determining if the pain has neuropathic or nociceptive qualities

- Determining attributes of patients with abdominal pain

- Assessing patients in the presence of sensory gastric dysfunction

- Objective mapping of the abdominal pain and determining central and/or peripheral
attributes of the abdominal pain

- Compare the Rome IV categories of gastric disorders (functional dyspepsia (FD),
epigastric pain syndrome (EPS), postprandial distress syndrome (PDS), chronic idiopathic
nausea and vomiting (CINV), rumination syndrome, cyclic vomiting syndrome, central
abdominal pain syndrome) to our present classification of gastroparesis and
gastroparesis-like disorder.

- Determine the prevalence of hypermobility spectrum disorders (HSD) in patients with
gastroparesis.

- Compare the water load satiety test (WLST) to intragastric meal distribution (IMD)
during scintigraphy and to symptoms of early satiety, postprandial fullness in patients
with symptoms of gastroparesis.

- Collect serum, plasma, and peripheral blood mononuclear cells (PBMC) that can be used
for subsequent analysis to address specific research questions.

Inclusion Criteria:

- Symptoms of gastroparesis of at least 12 weeks' duration with varying degrees of
nausea, vomiting, early satiety, postprandial fullness

- An etiology of either diabetic, idiopathic, or post-fundoplication (Nissen, Dor, or
Toupet) gastroparesis or gastroparesis-like disorder (symptoms of gastroparesis but
normal gastric emptying)

- Gastric emptying scintigraphy of solids using the 4-hour Egg Beaters® protocol (or
equivalent generic liquid egg white meal) within the last 6 months with either:

- Abnormal gastric emptying rate defined as an abnormal 2 hour (>60% retention) and/or 4
hour (>10% retention) result based on a 4 hour scintigraphic gastric emptying study.
(This group will comprise ~75% of patients in the registry.)

- Patients with a normal gastric emptying rate, but who have symptoms of gastroparesis.
(This group will comprise ~25% of patients in the registry.)

- Negative upper endoscopy or upper radiographic GI series within 2 years of
registration

- Age at least 18 years at initial screening visit

Exclusion Criteria:

- Inability to comply with or complete the gastric emptying test by scintigraphy
(including allergy to eggs)

- Use of narcotic analgesics greater than three days per week

- Presence of other conditions that could explain the patient's symptoms:

- Pyloric or intestinal obstruction: by EGD, UGI, or Abdominal CT

- Active inflammatory bowel disease

- Known eosinophilic gastroenteritis or eosinophilic esophagitis

- Primary neurological conditions that can cause nausea and vomiting such as increased
intracranial pressure, space occupying or inflammatory/infectious lesions

- Acute renal failure

- Chronic renal failure (serum creatinine >3 mg/dL) and/or on hemodialysis or peritoneal
dialysis

- Acute liver failure

- Advanced liver disease (Child's B or C; a Child-Pugh-Turcotte (CPT) score of ≥7)

- Prior gastric surgery including total or subtotal (near complete) gastric resection,
esophagectomy, gastrojejunostomy, gastric bypass, gastric sleeve, pyloroplasty,
pyloromyotomy. Note: patients with prior Nissen, Dor, or Toupet fundoplication will be
eligible for enrollment.

- Any other condition, which in the opinion of the investigator, could explain the
symptoms or interfere with study requirements

- Inability to obtain informed consent
