Overview

• A phase two study published in Allergy demonstrated that 67% of adult participants could consume the equivalent of five peanuts without severe reactions after oral immunotherapy.
• The treatment involves gradually increasing exposure to small amounts of peanut protein to build tolerance under strict medical supervision.
• This research addresses a long-standing gap in allergy treatments for adults, as prior desensitisation studies focused primarily on children.
• Participants, including Richard Lassiter, described the therapy as life-changing, with Lassiter now consuming peanuts daily without fear of severe reactions.
• Researchers emphasize the need for larger-scale studies to confirm findings and caution against attempting the therapy outside clinical settings.
