Nov. 16, 2023 – A brand new toothpaste is exhibiting promise as a remedy to assist adults who’re allergic to peanuts tolerate growing quantities of peanut protein.

The investigational toothpaste is labeled INT301 and it met its security objectives in an early randomized, placebo-controlled trial.

Thirty-two adults, ages 18-55, who have been allergic to peanuts, have been enrolled within the 4-month trial. The members have been randomly positioned into teams that acquired both growing quantities of the peanut protein within the toothpaste to check how a lot they might tolerate safely or a placebo toothpaste that had no peanut proteins. The toothpaste was squeezed from a metered dispenser to regulate the quantity. 

Neither the individual giving the members the toothpaste, nor the affected person knew which sort of toothpaste they obtained, to assist get rid of potential bias. 

“INT301 demonstrated security throughout all remedy teams,” mentioned the examine’s lead writer, William Berger, MD, an allergist and advisor for Intrommune, a biotechnology firm based mostly in New York Metropolis, which developed the toothpaste.

The toothpaste is a type of oral immunotherapy and it exposes the physique to an allergen in tiny however growing quantities over time to construct tolerance in case an individual is by accident uncovered to peanuts. In contrast to another oral immunotherapies, this one targets cells not slightly below the tongue, however in lots of elements of the mouth with the best potential for allergy desensitization, Berger mentioned.

Berger offered the findings of the OMEGA (Oral Mucosal Escalation Objective Evaluation) trial Nov. 11 on the American School of Allergy, Bronchial asthma and Immunology Annual Assembly in Anaheim, CA.

All Tolerated the Highest Dose

All members within the remedy arm constantly tolerated the best dose. As well as, there have been no average or extreme negative effects, Berger mentioned.

The principle response for many who obtained the remedy toothpaste was gentle itching contained in the mouth that could possibly be eradicated with antihistamines.

Trial regulators had requested the investigators to look at for any dental negative effects and Berger mentioned the toothpaste didn’t trigger well being within the enamel or mouth.

Early Indicators it’s Efficient

This early examine was primarily a security trial, however the investigators additionally discovered indicators with blood exams that the toothpaste works to assist desensitize adults to peanut protein. Effectiveness will probably be explored additional in a future trial.

Kristin Sokol, MD, MPH, an allergist/immunologist with Schreiber Allergy in Rockville, MD, mentioned, “As of now, the one choices we’ve for meals allergy remedy and administration are to inform our sufferers to fully keep away from a meals and carry epinephrine for his or her complete lives,” one other oral immunotherapy. 

Oral immunotherapy is time consuming, and there are substantial logistic issues. This toothpaste affords a better possibility that households can match into their day by day schedules, she mentioned.

“I am at all times on the lookout for choices like that,” Sokol mentioned. “Clearly there are extra research that should be carried out. I actually like the security knowledge on this. The zero incidence of anaphylaxis is actually necessary.”
