IMPACT study for peanut allergy completes enrollment

The Immune Tolerance Network (ITN) completed enrollment this week for the IMPACT Study in peanut allergy. There are 144 participants enrolled in the IMPACT Study (Oral Immunotherapy for Induction of Tolerance and Desensitization in Peanut-Allergic Children), which tests whether giving increasing doses of peanut protein (oral immunotherapy) over a two-year period can induce desensitization to peanut.  The trial will also address whether extended oral immunotherapy can create long-lasting tolerance to peanut.

American Academy of Pediatrics Endorses Early Peanut Introduction Based on ITN’s LEAP Study

On August, 31, 2015, interim guidance on the early introduction of peanut for the prevention of peanut allergy based on ITN’s “Learning Early About Peanut Allergy” LEAP Study was published in The Journal of Allergy and Clinical Immunology.

Request for Proposals: Clinical Trials of Immune Tolerance for Protein/Gene-replacement Therapy

The ITN is currently inviting proposals for novel clinical trials with the aim of inducing tolerance in patients who receive gene/protein-replacement (e.g. hemophilia, Gaucher’s disease) or other exogenous protein therapy, in which the patients are at risk for developing an immune response to the biologic agent. The ideal proposal would have a testable mechanism of tolerance induction and a strategy for assays investigating this mechanism.Full details are included in the RFP.

Early Consumption of Peanuts Prevents Peanut Allergy in High-Risk Infants

The results of the Immune Tolerance Network’s (ITN) “Learning Early About Peanut” (LEAP) study published today in the New England Journal of Medicine demonstrate that consumption of a peanut-containing snack by infants who are at high-risk for developing peanut allergy prevents the subsequent development of allergy.

ITN Opens Pilot Study to Compare Allergen Challenge Methods (CAT EEC Study)

On Monday the ITN opened a new pilot study to compare two different methods for assessing allergic responses: environmental exposure chambers and nasal allergen challenges. The CAT EEC study, “Cat Pilot Study – Environmental Exposure Chamber (EEC) vs. Nasal Allergen Challenge (NAC),” is being conducted at Inflamax Research, Inc. in Ontario, Canada and led by Drs.

Request for Proposals: ITN Seeks Antigen-Specific T Cell Tolerance Assays for Myelin-Associated Antigens in Multiple Sclerosis

The ITN has an interest in antigen-specific T cell tolerance in multiple sclerosis, an autoimmune disease in which autoreactive T cells specific for myelin-associated antigens are thought to play a role in pathogenesis. Assessment of antigen-specific tolerance in multiple sclerosis will require reliable assays to detect and phenotype T cell responses to myelin-associated antigens in a clinical trial setting.
