VE416 and Low-dose Peanut Oral Immunotherapy for Treatment of Persistent Peanut Allergy
Massachusetts General Hospital
Summary
This is a single-center, randomized, double-blind trial with four arms evaluating VE416 as pretreatment or concurrent treatment in comparison to low-dose peanut oral immunotherapy (PNOIT) alone.
Description
In this research study the investigators want to learn more about an investigational medicine called VE416 in combination with vancomycin (an antibiotic) while undergoing peanut oral immunotherapy. VE416 is a combination of dormant (inactive) bacteria given in a capsule. The bacteria are reactivated once they reach participants intestines and in combination with peanut flour may help to prevent participants from getting sick (upset stomach, breathing problems, and skin problems) when participants come into contact with peanuts. The investigators are doing this research study to find out if VE…
