Necessary efficacy measurements had been the proportion of sufferers who achieved a obvious stage of reduced eosinophils in the esophagus at week 24 and the alternate in Dysphagia Symptom Questionnaire (DSQ) ranking from baseline to week 24. The DSQ measures misfortune swallowing connected to eosinophilic esophagitis; whole rankings vary from 0 to 84, with larger rankings indicating worse signs.

In Section A, 60% of sufferers who acquired dupilumab achieved the pre-obvious stage of reduced eosinophils, when put next with 5% in the placebo group. Dupilumab-handled sufferers reported a median improvement of 22 aspects on the DSQ, when put next with a 10-level improvement in the placebo group.

In Section B, 59% of sufferers who acquired dupilumab reached the pre-obvious stage of reduced eosinophils when put next with 6% of the placebo group. Sufferers who acquired dupilumab reported a median improvement of 24 aspects in DSQ rankings versus 14 aspects for placebo. Patient views supported that DSQ rankings with dupilumab represented clinically meaningful improvement in dysphagia.
