Glycerol Tributyrate for MELAS Syndrome and Optic Neuropathy
Washington, District of Columbia
This is a parallel arm non-randomized dose-escalation, open-label basket exploratory phase 1 clinical trial where Mitochondrial encephalopathy, lactic acidosis, stroke-like episodes (MELAS) and Leber's hereditary optic neuropathy-Plus (LHON-Plus) participants will undergo simultaneous enrollment in two disease-based arms and receive daily oral doses of glycerol tributyrate to assess its safety and potential for efficacy using clinical, biochemical, and molecular evidence.
This study will utilize a two-month baseline lead-in phase to establish and document the clinical baseline for each participant in both arms in order to compare the molecular and clinical parameters. This is clinically relevant in light of the high clinical heterogeneity among subjects affected by the same mitochondrial disease (MELAS or LHON-Plus). For ethical concerns prompted by the lack of treatment for these two intractable and progressive mitochondrial diseases, there will not be a placebo control group. Thus, each participant will act as their own control and receive oral doses of glycerol tributyrate, eliminating the need for a placebo. Considering the high clinical heterogeneity among participants affected by MELAS or LHON-Plus and some clinical divergence between MELAS and LHON-Plus, this strategy is beneficial to every enrolled participants, as each will receive the investigational drug, glycerol tributyrate. In addition, this approach will determine the subject-specific maximal optimized dose in a personalized medicine-based approach.
After approval of the IRB protocol from the Institutional Review Board Data and signed consent form from all participants, this investigational basket clinical trial has three phases spanning over 20 months:
* A baseline lead-in phase (2 months) to collect participant-specific baseline for clinical, biochemical, molecular and metabolic biomarkers that will be monitored throughout the subsequent dose-escalation and clinical phases.
* A dose-escalation phase (6 months) to determine the participant-specific maximum tolerated dose (MTD) during which participant-specific clinical and biochemical biomarkers are collected every month.
* A clinical phase at a fixed subject-specific MTD dose (12 months) to collect participant-specific clinical, biochemical, molecular and metabolic biomarkers and to perform three scheduled skin biopsies: at the outset, mid-point, and the end of this clinucal phase. We have planned for a 12-month-long clinical phase at a fixed participant-specific MTD considering the absence of reliable predictors that makes idiosyncratic disease-specific symptoms for MELAS and LHON-Plus impossible to forecast among participant for assessing the potential efficacy of glycerol tributyrate by monitoring clinical symptoms specific for each disease. During the 12-month-long time-frame, disease-specific clinical symptoms will be collected as preliminary evidence of efficacy of glycerol tributyrate using disease-specific biomarkers.
Finally, discharge procedure during which the clinical investigator will record non-serious adverse events or serious adverse events for 7 or 30 days, respectively, after the last day of study participation.

Fosaprepitant vs Metoclopramide for Nausea and Vomiting
Bronx, New York
The study team proposes a double-blind, comparative effectiveness, randomized controlled trial (RCT) to address the following goal: to determine the relative efficacy and adverse event profile of fosaprepitant compared to the standard of care antiemetic metoclopramide. Fosaprepitant and its active metabolite aprepitant are a relatively new class of antiemetic that exclusively acts in the central nervous system by blocking neurokinin (NK-1) which is a key signaling molecule in the centrally mediated aspects of the vomiting reflex. Currently, fosaprepitant and aprepitant both have only two United Stated Food and Drug Administration (USFDA) approved indications for nausea and vomiting: chemotherapy-induced and postoperative. Neurokinin inhibitors are highly effective and generally well-tolerated. Therefore, this class of medication may be a more appropriate medication for the millions of patients with nausea and vomiting that seek care in emergency departments (EDs). Intravenous fosaprepitant is converted to the active metabolite aprepitant on the order of minutes and is significantly cheaper to procure at this time.

Oral Glutamine for Gulf War Syndrome
Memphis, Tennessee
Many veterans with Gulf War Illness developed chronic gastrointestinal symptoms during their deployment to the Persian Gulf. The pathophysiologic mechanisms of these chronic gastrointestinal symptoms are not well understood but cause significant morbidity in veterans. Our proposed studies will provide an innovative and novel treatment trial for chronic gastrointestinal symptoms in veterans with Gulf War Illness that were deployed into war zones. Given that there are currently no specific treatments for these disorders, and that current symptomatic approaches are far from ideal, proof of principle of our trial would be an extremely important advance as it would not only have a beneficial impact on the health of many thousands of our veterans, but also it would substantially reduce the many negative economic effects of this ailment on the VA Health Care System.

Probiotics for Autism
Montréal, Quebec
Children with autism spectrum disorder (ASD) present with stereotyped behaviors and often with comorbidities including gastrointestinal symptoms and sleep disturbances. These affect the quality of life of both children and parents. As of now, interventions available to manage ASD-related behaviors rely heavily on the services of professionals who are often difficult to access. What is even more striking is that there are currently no approved medications to treat the core symptoms of ASD. There is an important need for additional strategies to manage severity of ASD and to develop new treatments.
Targeting the bacteria living in the intestine, named 'gut microbiota', by using probiotics is an avenue that has been proposed by other groups to improve behaviors associated with ASD and gastrointestinal symptoms. However, these studies have important limitations, pressing the need for robustly designed interventions.
Previously, the PROBI-O-TISM pilot study was conducted at CHU Sainte-Justine. The investigators confirmed that the Bio-K+ probiotic beverage is acceptable and safe for autistic children and that the proposed study protocol is feasible. The study also led to promising preliminary results suggesting a beneficial effect of the probiotics on behaviors, gastrointestinal symptoms and sleep.
The proposed study will answer the question: ''Does supplementing with Bio-K+ probiotics reduce the severity of autistic behaviors and comorbidities in children with a diagnosis of ASD? '' The investigators will use a solid study design, a double-blinded randomized controlled-trial with placebo, to test the efficacy of a 14-week treatment with daily Bio-K+ probiotic supplement in children aged 4 to 11 years old. The investigators will also study the impact of the supplementation on other parameters such as quality of life, gut microbiota and brain signaling.
This is a unique opportunity to test a simple approach to improve behaviors and comorbidities in autistic children.

Enteral Nutrition Formula for ALS
Fort Lauderdale, Florida
The main objective of the proposed study is to evaluate if oral intake of EN formula preceding Gtube placement will impact tolerance upon placement and feeding via Gtube in pALS. This single arm intervention study all participants will receive the intervention and researchers will utilize validated indicators combined with clinical expertise to assess gastrointestinal symptoms of feeding intolerance before and after the intervention.
The main questions this study aims to answer are:
1. Wil participants meeting a greater percentage of their estimated nutritional needs at baseline present a slower disease progression rate and a lower incidence of GI symptoms of feeding intolerance when feeding via Gtube?
2. Will there be significant change in feeding intolerance when oral intake of enteral nutrition formula precedes feeding via Gtube?
This proposed study consists of three stages, as follows:
1. Pre-Intervention: The lead in period of one-week preceding intervention phase I will be timed to initiate 3 weeks before the scheduled Gtube placement procedure. Patients will be advised to maintain their usual food and beverage intake. Dietary intake and GI symptoms data will be collected by research personnel.
2. Phase I: Dietary intake data collected from the pre-intervention stage will be averaged and used to determine the number of cartons of enteral nutrition formula needed to meet the participants estimated nutritional needs. For two weeks +- 2 days participants will be directed to drink the number of cartons of a pre-selected enteral nutrition formula to meet their estimated nutritional needs when combined to their current oral dietary intake. A plant based EN formula (Kate Farms 1.4 Standard) commonly prescribed for pALS was selected to be provided to all patients in the study to keep this variable constant. Weekly data collection of dietary intake and GI symptoms will be ongoing.
3. Phase II: At the end of phase I, patients will undergo a Gtube placement at their selected medical facility. For the following two weeks +- 2 days participants will be directed to feed via Gtube the same number of cartons of the enteral nutrition formula used orally on phase I and make no changes to their current oral intake.

Guided Imagery Therapy for Abdominal Pain
Houston, Texas
Chronic abdominal pain is common among children, and the majority of cases are attributed to functional abdominal pain disorders. One approach to treating these disorders is by using psychological therapies. This clinical trial aims to see how well pre-recorded guided imagery therapy sessions help children's abdominal pain when delivered via a mobile application (app) on a smartphone or tablet.
Participants will complete a baseline abdominal pain and stooling diary to determine eligibility and other surveys. Participants who qualify will be placed in one of two groups by chance:
* Immediate Treatment Group
* Delayed Treatment Group
After randomization, the Immediate Treatment Group will get immediate access to the guided imagery therapy (GIT) mobile app intervention. This intervention asks participants to listen to a 10- to 15-minute GIT session 5 out 7 days weekly for 8 weeks in addition to their usual care for their abdominal pain. Then, participants will complete another abdominal pain and stooling diary and other psychometric surveys at the end of this intervention period.
After randomization, the Delayed Treatment group will be observed as they wait 8 weeks without app access. During this phase, these participants will continue to treat their abdominal pain in their usual fashion. After the end of this waiting period, participants will complete another abdominal pain and stooling diary and psychometric surveys again before gaining access to the GIT mobile app intervention. As noted previously, the mobile app intervention will ask participants to listen to a 10- to 15-minute GIT session 5 out of 7 days weekly for 8 weeks in addition to their usual care for their abdominal pain. Another abdominal pain and stooling diary and other psychometric surveys will be collected at the end of this app intervention.

Frequently Asked Questions
How much do Gastrointestinal Symptoms clinical trials pay?
Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.
How do Gastrointestinal Symptoms clinical trials work?
After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Gastrointestinal Symptoms trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Gastrointestinal Symptoms is 12 months.
How do I participate in a study as a "healthy volunteer"?
Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.
What does the "phase" of a clinical trial mean?
The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.
Do I need to be insured to participate in a Gastrointestinal Symptoms medical study?
Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.
What are the newest Gastrointestinal Symptoms clinical trials?
Most recently, we added Glycerol Tributyrate for MELAS Syndrome and Optic Neuropathy, Probiotics for Autism and Humiome® Post LB for Gastrointestinal Symptoms to the Power online platform.
