Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Develop dose limiting symptoms to peanut during a DPBCFC conducted in accordance with PRACTALL (Practical Issues in Allergology, Joint United States/European Union Initiative) guidelines at 1 mg, 3 mg, 10 mg, 30 mg, or 100 mg peanut protein.
- Has a positive SPT to peanut (≥3mm) and/or a positive peanut-specific IgE >0.35kU/L.
- For asthmatic patients, has a Spirometry or Peak Flow with Measurement of FEV1>=80% of predicted
- Has a negative urine hCG test if a female participant.
- Agrees to use an acceptable single-barrier form of birth control from enrollment through the exit DBPCFC study visit if female of childbearing potential and sexually active. An example of a single-barrier method of contraception includes condoms or oral contraceptives. Acceptable methods of birth control include implants, injectables, combined oral contraceptives, some intrauterine contraceptive devises (IUDs), sexual abstinence, a vasectomized partner, the contraceptive patch, the contraceptive ring, and condoms.
- Able to swallow 2 empty capsules size 00.
- Able to give informed assent and guardian willing to give informed consent.
- Willing and able to participate in the study requirements, including study visits, DBPCFCs, serial stool collection
- Willing to undergo telephone or email follow-up to assess for safety and adverse events.
Exclusion Criteria:
- Patients with a history of severe anaphylaxis to any food (hypotension requiring vasopressor support, hypoxia requiring mechanical ventilation, or neurological compromise)
- Patients with a history of IgE mediated reactions to food (excluding allergic reactions to peanut, tree nuts, egg and milk, provided that MTT does not contain traces of these l food estimated to be above the LOAEL in 5 capsules combined, and excluding oral allergy syndrome).
- Patients with chronic illness other than controlled asthma that is mild intermittent, mild- persistent or moderate persistent, mild eczema and allergic rhinitis. Exceptions can be made per PI discretion if illness is not expected to affect allergies or treatment.
- Recurrent or chronic infections necessitating frequent systemic (including oral) antibiotic administration.
- Patients on chronic systemic immunosuppressive therapies.
- Patients who are diagnosed with active, chronic urticaria.
- Patients who have received peanut oral immunotherapy within the past 6 months.
- Patients who are on the up-dosing phase of aeroallergen immunotherapy or patients who have received Omalizumab or dupilumab therapy within the past 6 months.
- Women who are pregnant or breast feeding or planning to get pregnant during the time of the study.
- Sexually active female patients who refuse to use contraception from enrollment through the third DBPCFC study visit
- Patient with GI conditions including inflammatory bowel disease, eosinophilic esophagitis, food protein induced enterocolitis, uncontrolled reflux despite medication, uncontrolled chronic constipation despite medication, esophageal dysmotility, swallowing dysfunction, delayed gastric emptying syndromes, pill esophagitis or history of aspiration pneumonia within 3 months prior to screening.
- Patient with current rheumatologic conditions. Exceptions can be made per PI discretion if illness is not expected to affect allergies or treatment.
- Patients with neutropenia <1000 unit of measure?
- Patients participating or planning to participate in the next 6 months in interventional research trials. Exceptions can be made per PI discretion.
- Patients who have received systemic corticosteroids therapy for 1 week or more over the past 2 months.
- Patient with an allergy to Vancomycin or Neomycin

- Masking: Quadruple
Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: antibiotic / MTT
Study subjects randomized to the experimental arm will receive oral antibiotics for 7 days as a way to modulate the composition of the gastrointestinal microbiota. Upon completion of oral antibiotics, subjects randomized to the experimental arm will be administeredf MTT under medical supervision. Subjects will be monitored and then discharged. Subjects will be instructed to take MTT capsules daily for 27 days. |
Subjects randomized to the MTT/antibiotic arm will be administered oral MTT capsules over the course of 28 days.
Subjects randomized to the MTT/antibiotic arm will receive oral antibiotics for 7 days prior to the MTT administration visit.
|
Active Comparator: placebo / placebo
Study subjects randomized to the placebo arm will receive oral placebo capsules instead of oral antibiotics, for 7 days, at the same frequency and capsule amount per dose. Upon completion of 7 days of placebo (matching the antibiotics given in the experimental arm), subjects randomized to the placebo arm will be administered capsules of placebo (matching the MTT capsules given in the experimental arm) under medical supervision. Subjects will be monitored and then discharged. Subjects will be instructed to take placebo capsules daily for 27 days. |
Subjects randomized to the placebo arm will be administered oral placebo capsules in place of MTT over the course of 28 days.
Subjects randomized to the placebo arm will receive oral placebo in place of antibiotics for 7 days prior to the MTT administration visit.
