Evaluating the Safety and Efficacy of Fecal Microbiota Transplant in Peanut Allergic Patients

Study Purpose

This is a Phase I trial to evaluate the safety and efficacy of fecal microbiota transplantation (FMT) in the treatment of peanut allergy. In this research the investigators would like to learn more about ways to treat peanut allergies. There is currently no known cure for peanut allergy. The primary aim is to assess safety and tolerability of oral FMT in patients with peanut allergy aged 18-40 years.

Recruitment Criteria

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Accepts Healthy Volunteers

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Trial Details

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

Trial ID:

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Peanut Allergy
Additional Details

This is a study of fecal microbiota transplantation (FMT) in the treatment of peanut allergy. The primary aim is to assess safety and tolerability of oral FMT in patients with peanut allergy aged 18-40 years. A total of 10 patients with peanut allergy will be enrolled after they fail a screening food challenge to peanut. Participating will be given oral encapsulated frozen FMT over 2 days. Patients will undergo a second and third food challenge after receiving FMT. The expected duration of the study for each subject will be one year. Stool collection, skin testing and blood samples will be done serially.
