|
E.4 | Principal exclusion criteria |
• History of cardiovascular disease • History of frequent or repeated, severe or life-threatening episodes of anaphylaxis or anaphylactic shock • History of other chronic disease (other than asthma, atopic dermatitis, or rhinitis) requiring therapy (e.g., heart disease, diabetes) • History of eosinophilic gastrointestinal disease • Current participation in any other interventional study • Subject is on ‘build-up phase” of immunotherapy to another allergen (i.e., has not reached maintenance dosing) • Severe asthma (2007 NHLBI Criteria Steps 5 or 6, see Appendix 2) • Mild or moderate (2007 NHLBI Criteria Steps 1-4) asthma, if uncontrolled as defined by any of the following: Forced expiratory volume in 1 second (FEV1) < 80% of predicted, or FEV1/FVC < 75%, with or without controller medications (only for age 6 or greater and able to do spirometry) or - Inhaled corticosteroid (ICS) dosing of > 500 mcg daily fluticasone (or equivalent ICSs based on National Heart, Lung, and Blood Institute [NHLBI] dosing chart) or - 1 hospitalization in the past year for asthma or - Emergency Room (ER) visit within 6 months • History of steroid medication use (via intravenous [IV], intramuscular [IM] or oral administration) in any of the following manners: daily oral steroid dosing for >1 month during the past year or burst or steroid course in the past 3 months or >2 burst oral steroid courses in the past year ≥1 week in duration • Inability to discontinue antihistamines 5 half-lives before the initial day of escalation, skin testing or DBPCFC • Lack of an available palatable vehicle food to which the subject is not allergic • Use of omalizumab within the past 6 months, or current use of other investigational forms of allergen immunotherapy (eg, oral or sublingual) or immunomodulator therapy (not including corticosteroids) • Use of beta-blockers (oral), angiotensin-converting enzyme (ACE) inhibitors, angiotensin-receptor blockers (ARB) or calcium channel blockers • Pregnancy or lactation • Having the same place of residence as another subject in the study • Participation in another clinical trial within 30 days prior to randomization |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary clinical efficacy endpoint is the proportion of subjects who tolerate at least 300 mg (443 mg cumulative) of peanut protein with no more than mild symptoms at the exit DBPCFC |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
After approximately 9 months of treatment |
|
E.5.2 | Secondary end point(s) |
• Change from baseline in tolerated dose of peanut protein at DBPCFC • Maximum dose achieved with no or mild symptoms at exit DBPCFC • Physician global assessment: Disease activity as measured on a 100 mm visual analogue scale (VAS) • Changes in peanut-specific IgE and IgG4, changes in skin prick test (SPT) mean wheal diameters • The safety of peanut OIT based on dosing symptoms and reported adverse events (AEs) including serious adverse events (SAEs) |
