1 Peanut Sublingual Immunotherapy Induction of Clinical Tolerance of Newly Diagnosed Peanut Allergic 12 to 48 Month Old Children

Primary Objective: To determine if 36 months of peanut SLIT as an early intervention in subjects ages 1 to 4 years induces clinical desensitization. The primary outcome of this objective will be a statistically significant difference in challenge scores between the treatment group versus the placebo group during DBPCFC (Double blind placebo controlled food challenge) performed after 36 months of peanut SLIT (desensitization). Challenge scores are measured by the amount of peanut protein participants are able to ingest successfully without symptoms of an allergic reaction. [Time Frame: Baseline, 36 months] Secondary Objectives: A secondary outcome of this objective will be a statistically significant difference in the challenge score of the treatment group versus the placebo group during the DBPCFC performed 3 months after discontinuing therapy (tolerance). To examine the change in immune parameters associated with peanut SLIT and the development of clinical tolerance. Through this objective, the investigators will seek to understand the molecular processes by which SLIT affects the immune system through evaluation of immune mechanisms in relationship to clinical findings of desensitization and tolerance. The investigators will delineate the impact of peanut SLIT on the subsequent cellular and humoral responses to peanut protein: 1) peanut specific IgE, IgG, and IgG4 response, 2) peanut specific basophil activation, 3) mast cell responses through skin prick testing, and 4) specific T-cell cytokine responses and T regulatory cell (TReg) activation. The investigators anticipate that the effect of peanut SLIT will occur by induction of TRegs, conversion of T cells from an allergic (TH2) to a non-allergic (TH1) lymphocyte response (measured by cytokines, antibody levels, and skin prick test size), a change in peanut-specific basophil activation, or through a combination of the above.

Primary Outcomes

Description: The primary outcome is to detect a statistically significant difference in reaction thresholds to peanut between the treatment group versus the placebo group during DBPCFC (Double blind placebo controlled food challenge) performed after 36 months of peanut SLIT (desensitization). Challenge scores are measured by the amount of peanut protein participants are able to ingest successfully without symptoms of an allergic reaction. The difference is measured through utilization of an extreme value hazard function.

Measure: Percentage of participants desensitized to peanut using peanut SLIT as an early intervention in subjects ages 1 to 4 years

Time: From baseline to 36 months

Secondary Outcomes

Description: Detect a statistically significant difference between reaction thresholds to peanut of the treatment group versus the placebo group during the DBPCFC performed 3 months after discontinuing therapy (tolerance).

Measure: Statistically significant difference in the challenge scores of the treatment group versus the placebo group during the DBPCFC performed 3 months after discontinuing therapy (tolerance)

Time: From baseline to 39 months

Description: To examine the change in immune parameters associated with peanut SLIT and the development of clinical tolerance.
