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

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Patient is a male or non-pregnant, non-breastfeeding female, and is age 18 years or older at the time of the Screening Visit.
  • Patient has a confirmed diagnosis of type 1 or type 2 diabetes mellitus.
  • Patient has a diagnosis of DGP with no history or evidence of mechanical obstruction, symptoms for at least 3 consecutive months preceding the Screening Visit, and delayed gastric emptying of solids documented within 2 years of the Screening Visit.
  • Patient has a normal EGD either during the Screening Period or within 2 years of the Screening Visit, with no evidence of structural or organic disease that may explain the patient's gastroduodenal symptoms.
  • Patient is compliant with eDiary completion.
  • Patient agrees to refrain from making any new, major lifestyle changes.
  • Patient is fluent and literate in English.

Exclusion Criteria:

  • Patient has a history or current symptoms of any organic or structural disease that, in the opinion of the investigator, can cause abdominal pain or discomfort and may confound the assessment of DGP symptoms.
  • Patients with rumination syndrome, cyclic vomiting syndrome, anorexia nervosa, or bulimia.
  • Patient is currently using a gastric electric stimulator or has had endoscopic pyloric injections of botulinum toxin within the 6 months prior to the Screening Visit.
  • Patient has been hospitalized within the 2 months prior to the Screening Visit for uncontrolled diabetes mellitus, DGP, or associated malnutrition.
  • Patient reports significant diarrhea during the four weeks prior to the Screening Visit, or more than 2 days during either week of the Pretreatment Period.
  • Patient has had surgery of the GI tract any time before the Screening Visit, an appendectomy or cholecystectomy during the 3 months before the Screening Visit, non-GI surgery of the abdomen, pelvis, or retroperitoneal structures during the 6 months, or other major non-GI surgery during the 30 days before the Screening Visit.
  • Patient has a history of cancer (resected basal cell or squamous cell carcinoma of the skin is acceptable).

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
Time Frame
Exploratory Endpoint - Daily Severity of Patient-reported Diabetic Gastroparesis Symptoms
Time Frame: Change from baseline: Treatment Period (weeks 1-4) compared with 2-week (baseline) Pretreatment Period
Change from baseline: Treatment Period (weeks 1-4) compared with 2-week (baseline) Pretreatment Period

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
