What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this research is to gather information on the safety and efficacy of using a prebiotic as an adjunctive therapy to peanut oral immunotherapy. The prebiotic is not an FDA approved drug or medication rather a fiber found at local grocery stores.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are currently using oral steroids, any type of immunotherapy, or certain other medications. It's best to discuss your specific medications with the trial team.

Is prebiotic supplementation safe for humans?

Prebiotics, like fructo-oligosaccharides and inulin, are generally considered safe and can positively affect gut bacteria, which may help with allergies. Studies in infants and animal models suggest they can improve gut health and immune tolerance without significant safety concerns.12345

How does the prebiotic treatment for peanut allergy differ from other treatments?

This prebiotic treatment for peanut allergy is unique because it focuses on altering the gut microbiota to promote immune tolerance, unlike traditional treatments that often involve avoiding peanuts or using medications to manage symptoms. Prebiotics like galacto-oligosaccharides and inulin help reinforce the gut barrier and modulate the immune system, potentially preventing allergies from developing.14567

What data supports the effectiveness of the treatment Prebiotics for Peanut Allergy?

Research suggests that prebiotics like inulin can help create a more tolerant immune environment and improve gut health, which may reduce food allergy symptoms. Studies in mice have shown that prebiotics can promote beneficial gut bacteria and reduce allergy symptoms, indicating potential benefits for peanut allergies.12458

Are You a Good Fit for This Trial?

This trial is for children aged 4 to 17 with a confirmed peanut allergy, as shown by specific immune markers and reactions in tests. They must have had symptoms at low doses of peanut protein or meet other criteria indicating sensitivity to peanuts. Participants cannot have certain chronic diseases, be on immunomodulatory medications, or be involved in another interventional study.

What Are the Treatments Tested in This Trial?

Interventions

  • Placebo
  • Prebiotic
Trial Overview The Pinpoint Trial is testing the safety and effectiveness of adding a prebiotic fiber (found in grocery stores) to peanut oral immunotherapy for treating peanut allergies. The study will compare the results of this combination therapy against a placebo alongside standard treatment.

Published Research Related to This Trial

Infants consuming formula with prebiotics (galacto-oligosaccharides and fructo-oligosaccharides) showed a significantly higher abundance and proportion of beneficial bifidobacteria compared to those without prebiotics, indicating a positive effect on gut microbiota composition.
The prebiotic-containing formula was well tolerated and resulted in lower fecal pH, but did not affect stool patterns, tolerance, or growth compared to the control group, suggesting it is a safe option for infant nutrition.
