Fig 1 Study timeline with key features highlighted. Subjects were randomized at T2 to either SLIT (goal dose, 7 mg), OITB (goal dose, 1000 mg), or OITA (goal dose, 2000 mg). CM-specific IgE, CM-specific IgG4, and CM-titrated skin prick test (SPT) results were obtained in all subjects at T1, T3 to T5, and T7. Basophil studies were done at T1, T2 to T5, and T7.

Fig 2 Food challenge outcome. The CM protein threshold is shown for baseline (T1), after 12 weeks of maintenance (T4), after 60 weeks of maintenance (T5), and 1 week (T6) and 6 weeks (T7) off therapy. A, SLIT/SLIT group. B, SLIT/OITB group. C, SLIT/OITC groups. Bars represent medians. ∗P < .05 and ∗∗P < .01 compared with T1.

Fig 3 Mechanistic changes. Individual line plots showing changes with treatment for the 3 randomization groups (A, SLIT/SLIT group; B, SLIT/OITB group; and C, SLIT/OITA group) in CM-specific IgE level (1), CM-specific IgG4 levels (2), and end point titration skin prick test responses. Shown is the average wheal size over 5 CM dilution. Bars represent medians. The shaded blue area represents the period of withdrawal of therapy. ∗P < .05 and ∗∗P < .01 compared with T1.

Fig 4 Basophil activity. A, HR in media alone (SHR) or after stimulation with CM extract, goat anti-human IgE antibody (IgE), peanut extract (PN), or N-formylmethionine (f-met) at T1 to T5 and T7. B, Constitutive surface expression of CD63 and CD203c and intracellular Syk by basophils at T1 to T5 and T7. A box-and-whisker plot is shown; outliers are not shown. ∗P < .05 and ∗∗P < .01 compared with T1.

Fig E1 Predictors of development of tolerance among subjects undergoing OIT. CM-specific IgE levels, CM-specific IgG4 levels, CM end point titration skin prick test responses, spontaneous basophil CD63 and CD203c expression, SHR, and HR to CM, T1 to T7 in subjects receiving SLIT/OIT who passed the final food challenge (Tolerant) and those who failed or did not qualify for the food challenge (Non-Tolerant) are shown. At T1, CM-specific IgE levels were lower in the tolerant group (P = .03). Both constitutive CD63 and C203c expression increased at T2 in only those who did not have tolerance (P < .001 and P = .001, respectively, for the difference in the change from T1 between groups). There were no other statistically significant differences at baseline, over time, or at T5 between the groups.
