- Ages 18 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult
Study population: This study will enroll patients with gastroparesis and delayed gastric emptying. These patients can have either diabetic, idiopathic, or post-Nissen fundoplication gastroparesis. In addition, patients with symptoms similar to gastroparesis, but with normal gastric emptying will be enrolled as a reference group.
Who may be able to join
- Symptoms of gastroparesis of at least 12 weeks duration (do not have to be contiguous) with varying degrees of nausea, vomiting, early satiety, post-prandial fullness, and/or abdominal pain
- An etiology of either diabetic, idiopathic, or post-Nissen fundoplication gastroparesis
- Gastric emptying scintigraphy of solids and liquids test using 4 hours Egg Beaters® protocol 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 low fat Egg Beaters® gastric emptying study performed at a GpCRC clinical center.
- Patients with a normal gastric emptying rate but with symptoms of gastroparesis may be enrolled and classified as possible gastroparesis or gastroparesis-like with normal gastric emptying
- Age at least 18 years at initial screening visit
- Upper endoscopy results within last 2 years
Who cannot join
- Inability to comply with or complete the gastric emptying scintigraphy test (including allergy to eggs)
- Presence of other conditions that could explain the patient's symptoms:
- Pyloric or intestinal obstruction as determined by endoscopy, upper GI series or abdominal CT scan
- Active inflammatory bowel disease
- Known eosinophilic gastroenteritis
- Primary neurological conditions that could cause nausea and/or vomiting such as increased intracranial pressure, space occupying or inflammatory/infectious lesions

- Acute liver failure
- Advanced liver disease (Child's B or C; a Child-Pugh-Turcotte (CPT) score of ≥7 )
- Acute renal failure
- Chronic renal failure (serum creatinine >3 mg/dL) and/or on hemodialysis or peritoneal dialysis
- Total or subtotal (near complete) gastric resection, esophagogastrostomy, gastrojejunostomy, or gastric bypass. Note: patients with prior fundoplication will be eligible for enrollment.
- Any other plausible structural or metabolic cause
- Any other condition, which in the opinion of the investigator would interfere with study requirements

About this study
Official title: GpR 2: Continuation of the NIDDK Gastroparesis Registry for the Characterization and Clinical Course of Gastroparesis Patients
To expand a registry of patients for the study of the epidemiology, etiology, and degree of morbidity associated with gastroparesis.
Read the detailed description
The Gastroparesis Registry 2 (GpR 2) will enroll new patients and patients from the initial NIDDK Gastroparesis Clinical Research Consortium Gastroparesis Registry (GpR) of gastroparesis patients which was initiated in February 2007 and completed in March 2011.
To continue to follow and expand the data collections of a well-characterized cohort to further define the natural history and clinical course of gastroparesis.
To provide a reliable source for recruitment of well-characterized patients with gastroparesis for 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.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01696747, which also lists 14 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Feb 2022; AzTrials last refreshed its copy on 29 Oct 2026.
