简要总结
The purpose of this trial is to study the safety of rescue peanut oral immunotherapy followed by the introduction of dietary peanut for patients with peanut allergy who have lost desensitization during a peanut immunotherapy trial.
详细描述
Salvage Peanut Oral Immunotherapy Study is a single-arm, open label trial of peanut flour oral immunotherapy (OIT) administered for 6 months followed by introduction of dietary peanut for an additional 6 months.
The peanut OIT phase will involve approximately 3 months of dose escalation up to a maintenance dose of 300 mg peanut protein. This is followed by 3 months of daily maintenance dosing with 300 mg of peanut protein. Patients are then transitioned to the dietary peanut phase ingesting common foods containing approximately 300 mg of peanut protein daily.
Safety will be assessed during both peanut OIT and dietary peanut phases with adverse events recorded including gastrointestinal side effects. They will also be monitored for any anaphylaxis or injectable epinephrine administration. Data regarding compliance with peanut OIT will be collected as well.

入选标准
- •Subjects who have completed an immunotherapy trial for peanut allergy within the last 6 months and are unable to tolerate ≥ 300mg of peanut.
- •Age 1-65 years of either sex, any race, any ethnicity. Written informed consent from patient or parent/guardian (if < 18 years) with participant's assent.
排除标准
- •Current participation in an interventional study for peanut allergy
- •History of a severe anaphylactic reaction to peanut, defined as hypoxia, hypotension, or neurologic compromise (cyanosis or SpO2 ≤ 92% at any stage, hypotension, confusion, collapse, loss of consciousness, or incontinence)
- •Eosinophilic or other inflammatory (e.g. celiac) gastrointestinal disease
- •Severe asthma (2007 NHLBI Criteria Steps 5 or 6 , Appendix 2)
- •Use of B blockers (oral), angiotensin-converting enzyme (ACE) inhibitors, angiotensin-receptor blockers (ARB) or calcium channel blockers
- •Significant medical condition (e.g., liver, kidney, gastrointestinal, cardiovascular, hematologic, or pulmonary disease) which would put the subject at risk for induction of severe food reactions.
- •Pregnancy or lactation.
