Fecal microbiota transplant trial for peanut allergies

Overview

Researchers from Boston Children’s Hospital and Harvard Medical School conducted a Phase I clinical trial testing oral encapsulated fecal microbiota transplantation (FMT) to treat severe peanut allergies. The study, published in Science Translational Medicine, involved 15 adults who ingested 36 capsules containing frozen microbes from healthy donors.

The trial was divided into two phases. In the first phase, 10 participants received a single dose; four months later, three participants demonstrated an increased threshold for peanut reactivity. In the second phase, five participants received antibiotic pretreatment before the FMT to facilitate bacterial colonization. Of these five, three individuals were able to ingest more than four peanuts before experiencing symptoms.

Results indicated that the treatment was well-tolerated. Biological analysis suggests the mechanism involves an increase in regulatory T cells, changes in gut bacteria, and higher bile-acid levels, which may help regulate the immune system to promote food tolerance.

Building on these findings, recent medical research is exploring the use of advanced biomarkers to move toward a model of personalized precision medicine. A review in Clinical Reviews in Allergy & Immunology highlights the potential of using basophil activation tests and microbiota analysis to help clinicians predict the severity and reaction thresholds of plant-based food allergies. While these developments in microbiome manipulation and biomarker identification show promise, researchers emphasize that larger clinical trials and validations are still required to confirm long-term efficacy and safety.
