About this study

The goal of this clinical trial is to compare soy isoflavones to placebo in children who at risk of asthma and have a genetic variation which results in them making more of a pro-inflammatory protein, plasminogen activator inhibitor-1. The main questions this trail seeks to answer is: will soy isoflavones decrease the proportion of infants with aT2 high endotype at the end of treatment, and secondarily decrease the number of wheezing episodes in these children when given in the first year of life. Participants will be asked to ingest soy isoflavone or placebo twice daily mixed into a liquid or puree vehicle for 7 months from randomization. There will be 3 mandatory in-person visits, and 6 virtual visits in the first year. There will also be 11 monthly questionnaires and 1 in person visit in the observation year. Participants will have 4 nasal swabs, 3 blood draws, and also provide 4 stool samples over the course of the study.
