Plant Exosomes +/- Curcumin to Abrogate Symptoms of Inflammatory Bowel Disease

November 2, 2022 updated by: Susan Galandiuk, University of Louisville

Pilot Clinical Trial Investigating the Ability of Plant Exosomes +/- Curcumin to Abrogate Symptoms of Inflammatory Bowel Disease (IBD)

The trial will test the hypothesis that edible structures within plant cells (ginger) will have clinically important anti-inflammatory effects on the gut lining of patients with inflammable bowel disease.

To evaluate the safety and tolerability of exosomes with and without curcumin in patients with Inflammatory Bowel Disease (IBD); To estimate the effect of ginger exosomes or curcumin alone or combined with curcumin on the symptoms and disease score in patients with refractory IBD describe toxicities associated with ginger exosomes; to evaluate the effect of ginger exosomes on biomarkers of inflammation.

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

Up to 90 patients with Chronic IBD will be enrolled, with the goal of having three arms of 30 subjects in each group who are eligible for evaluation.

This exploratory trial is designed to estimate the effect of ginger exosomes or curcumin on IBD symptoms compared to ginger exosomes plus curcumin. In this prospective and randomized study the main focus is to compare exosomes alone, curcumin, and exosomes plus curcumin. Three primary stratification factors race (white and black), gender and type of IBD (CD and UC) will be used. plan Zelen's (1974) method will be used to avoid imbalance allocation within each stratum. A block size of 4 will be used. We plan to enroll all eligible patients visiting the clinic, as well as eligible patients referred from other gastroenterologists. All eligible visiting our clinic will be enrolled. By enrolling consecutive patients, we reduce selection bias. A patient will be enrolled only once.

The most important aim of this study is to compare the IBD symptoms in exosomes alone and exosomes plus curcumin groups of patients. The symptomatology will be measured in each group and compared to the self-reported score. We will use the incidence rate of bloody stool to justify the sample size. With the combination treatment (ginger exosomes plus curcumin as compared to curcumin alone) we hope to reduce symptoms by at least 30%. Using a two sample one-sided t test for comparing mean differences in Inflammatory Bowel Disease Questionnaire, with 30 subjects in each group and using alpha=5%, we will have 80% power to detect effect size of 0.65 Standard Deviation, which is a large effect size (Cohen, 1988).. When the reduction in sample size due to missing data or other reasons, we will have reduced power to detect the difference in two groups.

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.

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 in inflammation on Colonoscopy
Time Frame: 30 days
Decrease in inflammatory cells in the biopsy after treatment versus before treatment.
30 days

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.
