Skin Patch for Peanut Allergy Shows Promise
After one year, an ongoing clinical trial suggests that a skin patch for treating peanut allergies is safe and somewhat effective—especially for younger children. Peanut allergies are a rising health concern—prevalence has increased significantly over the past decade. Just a trace amount of peanut protein can cause a serious, possibly life-threatening, reaction in some people with peanut allergies.
The clinical trial, which is sponsored by the National Institute of Allergy and Infectious Diseases of the NIH, involves 74 participants between the ages of four and 25. For the study, each participant applies a patch containing a high dose of peanut protein, a low dose of peanut protein, or a placebo, every day.
According to researchers, 48 percent of participants who received high-dose treatment, 46 percent of those who received a low dose, and 12 percent who received a placebo were able to tolerate 10 times more peanut protein than at the start of the study. Children between the ages of four and 11 experienced the best results. Testing of the patch, which is not approved by the FDA, will continue.
