Change in the Cumulative Tolerated Dose (CTD) of Milk Protein During DBPCFC From Baseline to Week 18 Across Cohorts as Pairwise Comparisons of All Treatment Groups Secondary · Baseline and week 18

Baseline values reflect the log10 of cumulative tolerated dose (CTD) of milk protein. The change metric reflects the order of magnitude of paired differences in CTD between baseline and week 18.

Sponsor's own description

This is a phase 2, multicenter, randomized, double-blind, parallel group, 2 arm study in approximately 40 subjects aged 4 to 50 years, inclusive, who are allergic to cow's milk. The primary objective is to assess whether dupilumab as an adjunct to milk oral immunotherapy (OIT) compared to placebo improves the safety of milk OIT and rates of desensitization, defined as an increase in the proportion of subjects who pass a double-blind placebo-controlled food challenge (DBPCFC) to at least 2040 mg cumulative milk protein at week 18.
