Food immunotherapy has been the focus of several allergy research initiatives over the last decade. Although many questions remain unanswered, the evidence suggests that this treatment might be available in the near future outside clinical trials. Additionally, pharmaceutical companies, in light of promising early-stage results, have shown interest in developing commercially available products, thus increasing the likelihood that new immunotherapy treatments will be introduced, especially for peanut allergy. Given this optimistic scenario and given the prospect of rigorously developed products for peanut allergy treatment, each allergist will need to understand the specificities of these treatments and their expected efficacy and adverse event profiles. Thus it is imperative that allergists understand the differences in efficacy between the different management options, as well as how the end points are measured in the relevant literature. However, given the significant heterogeneity detected among food immunotherapy trials, this task might not be as straightforward as desired. This article aims to dissect how primary efficacy end points are defined and assessed to facilitate understanding of the design of these trials and the potential effect that this variation might have on the reported outcomes.
