Abstract Background Health‐related quality of life (HRQoL) is significantly and substantially reduced in individuals with peanut allergy due to many factors associated with unanticipated or potentially fatal reactions. Further insight on the impact of peanut oral immunotherapy in managing peanut allergy on HRQoL is needed. The aim of this analysis was to assess effects of peanut (Arachis hypogaea) allergen powder‐dnfp (PTAH), a biologic drug for peanut oral immunotherapy, on HRQoL from three phase 3 and two follow‐on trials of PTAH. Methods HRQoL assessments from participants aged 4–17 in the PALISADE (ARC003), ARC004 (PALISADE follow‐on), ARTEMIS (ARC010), RAMSES (ARC007), and ARC011 (RAMSES follow‐on) trials were included in this analysis. Responses on the Food Allergy Quality of Life Questionnaire (FAQLQ) and Food Allergy Independent Measure (FAIM) were evaluated by age group and respondent (self or caregiver proxy). Data were analyzed with descriptive statistics and Student t tests. Results Baseline FAQLQ and FAIM total scores appeared comparable between PTAH‐ and placebo‐treated participants. Self and caregiver proxy‐reported total scores on the FAQLQ for PTAH‐treated participants generally improved at trial exit versus baseline; FAIM total scores improved throughout all trials. The tendency for improvement in FAQLQ total scores from baseline for PTAH appeared larger in self versus caregiver proxy‐reports. Between treatment groups, PTAH was generally favored in the PALISADE and ARTEMIS trials; differences varied in the RAMSES trial based on age and respondent types. Conclusions PTAH for the management of peanut allergy in children appeared to have a beneficial effect on HRQoL in trials. Improvements were seen despite rigors of trial participation.

RationaleFood allergy is documented to result in considerable morbidity, negative impact on quality of life, and substantial medical care costs. Although anecdotal data suggest widely varying practices in the diagnosis and management of food allergies, the diversity and relative frequency of these practices have not been documented.MethodsA questionnaire was developed evaluating allergists' management approaches of individuals with peanut allergy (PA) in Germany (DE), France (FR), and the United Kingdom (UK).ResultsHere, we report the survey results from a total of 109 allergists from DE, FR and the UK. They reported to confirm PA at initial diagnosis using skin prick test (≥60%), while allergists from DE and FR reported using allergen-specific IgE testing more (>86%) compared to the UK (75%). Half of the responders reported assessing the patient's quality of life. 63% allergists reported retesting for PA resolution at a later date, with 45% allergists indicated to recommend ingestion of a normal serving of peanut regularly upon resolution. Lack of effective PA treatment was reported to be a 'very significant' barrier for optimal PA treatment, with allergists being less than 'moderately familiar' with data from clinical trials testing new treatments options for PA. Lastly, allergists stated that the severity of patient's PA ranked as the most important factor in their decision to recommend oral immunotherapy for PA treatment.ConclusionsThis survey provides essential insights into the practice of allergists and highlights some areas that would inform strategies for education and improving PA healthcare.
