A Phase II Trial to Evaluate the Safety and Efficacy of Oral Encapsulated Microbiota Transplantation Therapy in Peanut Allergic Patients
Rima Rachid
Summary
This is a phase II trial that aims at evaluating the safety and tolerability of oral encapsulated fecal microbial transplantation therapy (MTT) in peanut allergic patients. In this research the investigators would like to learn more about ways to treat peanut allergies. The primary objective for Part A is to evaluate whether MTT with antibiotic pretreatment can increase the threshold of peanut reactivity during a double-blind placebo-controlled food challenge from \<=100 mg peanut protein to 300 mg after 28 days of MTT /placebo therapy and 4 months post therapy initiation. The primary objective for Part B is to evaluate whether MTT with antibiotic pretreatment can lead to sustained unresponsiveness (SU) defined as tolerating the same dose of peanut protein administered during a food challenge at baseline and 12 weeks after OIT cessation.
Description
Part A is a This is a phase II randomized double-blind placebo-controlled arm trial that aims at evaluating the efficacy and safety and tolerability of microbial transplantation therapy (MTT) in peanut allergic patients. After reacting to \<=100 mg peanut protein during initial DBPCFC, patients will be randomized to receive either oral Vancomycin and Neomycin or placebo/placebo for 7 days. Patients will then come to the Experimental and Therapeutic Unit (ETU) to receive orally 5 capsules of MTT or placebo under medical supervision. Patients will then take 5 capsules of MTT or placebo the next…
