Buspirone for Early Satiety and Symptoms of Gastroparesis (BESST)

June 14, 2023 updated by: Johns Hopkins Bloomberg School of Public Health

Buspirone for Early Satiety and Symptoms of Gastroparesis: A Multicenter, Randomized, Placebo-Controlled, Double-Masked Trial (BESST)

This study evaluates whether the study medication, buspirone, an antianxiety drug, improves the symptoms of gastroparesis in patients with gastroparesis symptoms and at least moderately severe symptoms of fullness and/or inability to eat a full meal. Half the patients will receive buspirone and half the patients will receive a placebo.

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 is a multi-center, randomized, double-masked, placebo-controlled, parallel treatment groups phase 2 trial to determine the effect of buspirone, a 5-hydroxytryptamine (5-HT) 1a receptor agonist, on early satiety and postprandial fullness in participants with symptoms of gastroparesis and with at least moderately severe symptoms of early satiety and/or postprandial fullness. After enrollment, participants aged 18-75 years will be treated with buspirone (10 mg three times per day) or a matching placebo for 4 weeks, followed by a 2-week post-treatment washout period. The primary outcome for the study is 4-week change (week 4 minus baseline) in the 4-item postprandial fullness/early satiety subscore (higher scores indicate worse symptoms) from the Patient Assessment of Gastrointestinal Disorders Symptom Severity Index (PAGI-SYM) Gastroparesis Cardinal Symptom Index (GCSI). We hypothesize that buspirone treatment will improve symptoms of postprandial fullness/early satiety compared to treatment with placebo, as indicated by a lower (smaller, more negative) 4-week change in the postprandial fullness/early satiety subscore in the buspirone arm compared to the placebo arm; change for a participant will be calculated as subscore at 4-weeks minus subscore at baseline.

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.

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
4-Week Change in the Postprandial Fullness and Early Satiety Symptoms Severity
Time Frame: baseline and 4-weeks
The outcome is assessed using the self-reported early satiety/postprandial fullness subscore (ES/PPF), which is computed as the average of 4 scores for 4-items on the Gastroparesis Cardinal Symptom Index (GCSI) survey: stomach fullness, inability to finish a normal-sized meal, feeling excessively full after meals, and loss of appetite. Each item is scored from 0 (no) to 5 (very severe) symptoms in the past 2-weeks; the subscore ranges from 0 to 5. The change is computed as the subscore at 4-weeks minus the baseline subscore.

Change From Baseline at 4-weeks in the Water Load Satiety Test (WLST)
Time Frame: baseline and 4-weeks
The Water Load Satiety Test (WLST) is the amount of water a patient can consume until full in 5 minutes. The volume of water is recorded.

Plan for Individual participant data (IPD)

Plan to Share Individual Participant Data (IPD)?

YES

IPD Plan Description

The study will comply with the NIH Data Sharing Policy. The data will be first de-identified so that no individual participant identifiers will be included in the dataset (no names, addresses, dates, comments, etc). If a characteristic is an extreme value for this population, then those values will be categorized into one frequency group. If a CSR has multiple versions, then all data will be recoded into the format of the most current form version. A random unique identification number will be substituted for the unique BESST identification number. If a clinical item was obtained from surveys with restrictions due to licensing, then that data will be excluded. The data will be shared in 2 stages: the first will be the analytic datasets to produce the primary outcome paper. For this dataset, the documentation will include analytic code. The full dataset by CSR will be provided in the second stage.

IPD Sharing Time Frame

The analytic datasets to produce the primary result manuscript will be submitted within one year of publication of the primary result manuscript. The full clinical dataset for all Clinical Study Reports (CSRs) without proprietary restrictions will be submitted within 2 years of the primary result manuscript publication.
