July 21, 2025 updated by: Matthew Allemang

Impact of Endoscopic Per-Oral Pyloromyotomy (POP) on Glycemic Control in Gastroparesis Patients With Poorly Controlled Diabetes Mellitus

This study will assess changes in glycemic control in 40 patients with diabetes who undergo per-oral pyloromyotomy (POP) for medically refractory gastroparesis.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This will be a prospective study using HbA1c values and continuous glucose monitoring (CGM) to assess changes in glycemic control in patients with diabetes who undergo per-oral pyloromyotomy (POP) for medically refractory gastroparesis. The study cohort will consist of 40 patients with poor glycemic control who undergo POP. The investigators propose a prospective cohort study using CGM to compare glycemic profiles before and after POP in patients with diabetic gastroparesis. The investigators hypothesize that patients will have improvement in glycemic control and reduced variation in blood glucose levels (% time in hypo/hyperglycemia) after undergoing POP. These results will aid in clinical decision making, and may indicate an earlier need for endoscopic intervention in patients with uncontrolled diabetes and gastroparesis.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Patients 18 years of age and older
  2. Patients with gastroparesis with an average HbA1c> 7.5% over the past 3 months
  3. Patient that have a diagnosis of gastroparesis established by documented delayed gastric emptying by either a wireless motility capsule study or a nuclear gastric emptying study, with no evidence of gastric obstruction.
  4. Patients are able to complete all study requirements

Exclusion Criteria:

  1. Patients <18 years of age
  2. Patients with gastroparesis with an average HbA1c< 7.5% over the past 3 months
  3. Patients unable or refuse to complete the study requirements
  4. Patients who are unable or refuse to wear a CGM sensor
  5. Patients with insulin pumps
  6. Patients who already use a CGM

Arms and Interventions

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Endoscopic Per-Oral Pyloromyotomy (POP)
The study cohort will include 40 patients with a HbA1c >7.5% with medically refractory gastroparesis who are scheduled to undergo POP. Each patient will undergo two 10-day periods of CGM at an interval of approximately seven months, one month prior to the procedure and six months after. Symptoms and diabetes management improvement will be measured by the Gastroparesis Cardinal Symptom Index (GCSI) scores and the Diabetes Self-Management Questionnaire (DSMQ).
Procedure: Pyloromyotomy

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from Baseline in Hemoglobin A1C levels
Time Frame: Baseline and 6 Month
Glycemic control will be evaluated by measuring change in Hemoglobin A1C (HbA1c) levels. Poor glycemic control defined as an average HbA1c > 7.5%. Change = (Six Month Score - Baseline Score)
Baseline and 6 Month
Change from Baseline in Glucose Levels measured by Continuous Glucose Monitor
Time Frame: Baseline and 6 Month
Glycemic control will be evaluated by measuring average glucose levels using Continuous Glucose Monitors (CGM). Normal glucose levels 74-99 mg/dL. Change = (Six Month Score - Baseline Score)
Baseline and 6 Month

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change from Baseline on Diabetes Self-Management Questionnaire
Time Frame: Baseline and 6 Month
The Diabetes Self-Management Questionnaire (DSMQ) is a self reported instrument assessing diabetes self-care activities. Possible scores range from 0 (Does not apply) to 3 (Applies to me very much). Change = (Six Month Score - Baseline Score)
Baseline and 6 Month
Change from Baseline on Gastroparesis Cardinal Symptom Index
Time Frame: Baseline and 6 Month
The Gastroparesis Cardinal Symptom Index (GCSI) is a validated patient-administered questionnaire that is used to assess gastroparesis symptom severity. Possible scores range from 0 (None) to 5 (Very Severe). Change = (Six Month Score - Baseline Score)
Baseline and 6 Month
