Official title
Down Regulation of Oxidant Induced Airway Inflammation Through Modulation of NRF2
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Purpose: To determine if modulation of NRF2 with a Sulforaphane enriched supplement modifies responses to O3. Participants: Recruitment of up to 70 healthy volunteers, ages 18-50, for completion of 36 volunteers. Procedures: This is a randomized, placebo controlled 2x2 crossover study of treatment with an NRF2 modifier versus placebo in healthy volunteers which will examine airway inflammation before and 4 hours after a 2 hour 0.4 ppm O3 exposure. Participants will be randomized to received either the NRF2 modifier, SFN oral supplement (i.e. broccoli sprout shake), or placebo (alfalfa shake) for 3 days followed by a 0.4 ppm O3 exposure for 2 hours. At least 2 weeks later subjects will return for a 2nd supplementation treatment (using the alternative supplement to that provided initially) followed by an ozone exposure identical to the initial one.
