Percent of Participants Who Were Histologic RespondersPrimary· Week 16
Histologic response was defined as a peak eosinophil count \</= 6/high power field (light microscopy) (HPF) across all esophageal levels at the final treatment evaluation (Week 16). An independent, central pathologist determined the peak eosinophil count from the proximal, mid-, and distal levels and selected the maximum peak value. Histopathology data were collected in a blinded fashion.
Change From Baseline in The Dysphagia Symptom Questionnaire (DSQ) Score at The Final Treatment Period EvaluationPrimary· Baseline, Week 16
Participants' dysphagia symptoms were evaluated using the 4-item DSQ. The questionnaire was developed by the Sponsor, as an ePRO measure, according to the principles of the Final Guidance for Industry for Patient Reported Outcome Measures (PRO Guidance December 2009). All participants used a diary, and responded to Questions 1 (did you eat solid food) and 2 (did food pass slowly or get stuck). If the participant's answer to Question 2 was 'No', the diary ended for that day. If a participant answered 'Yes', he/she advanced to Questions 3 (did you have to do anything to make the food go down or
Change From Baseline in The DSQ Score Over TimeSecondary· Baseline, Weeks 8 and 12
Participants' dysphagia symptoms were evaluated using the 4-item DSQ.

Change From Baseline in The DSQ Score For The 50th Percentile of Participants at The Final Treatment Period EvaluationSecondary· Baseline, Week 16
A cumulative distribution function curve was constructed to illustrate the cumulative proportion of participants (x-axis) vs. the change in the DSQ score from baseline to the final treatment evaluation (y-axis). The 50th percentile is participants with a DSQ score that is in the middle of the distribution of all scores. A negative change from baseline indicates that symptoms decreased.
Percent of Participants With a Peak Eosinophil Count </= 15/High Power Field (Light Microscopy) (HPF) And </= 1/HPF at The Final Treatment Period EvaluationSecondary· Week 16
An independent, central pathologist determined the peak eosinophil count from the proximal, mid-, and distal levels and selected the maximum peak value across all available esophagus levels. Histopathology data were collected in a blinded fashion. The values reported are for participants with histologic response.
Percent of Participants With a >/= 30% And >/= 50% Reduction In The DSQ Score From Baseline to The Final Treatment Period EvaluationSecondary· Baseline, Week 16
Participants' dysphagia symptoms were evaluated using the 4-item DSQ. The questionnaire was developed by the Sponsor, as an ePRO measure, according to the principles of the Final Guidance for Industry for Patient Reported Outcome Measures (PRO Guidance December 2009).

Percent of Participants Who Were Overall Responders at The Final Treatment Period EvaluationSecondary· Week 16
Overall response was defined as a reduction in the 2-week DSQ score of \>/= 30% and \>/= 50% from baseline to the final treatment period evaluation and a peak eosinophil count of \</= 6/high power field (light microscopy) (HPF) across all available esophageal levels at the final treatment period evaluation. An independent, central pathologist determined the peak eosinophil count from the proximal, mid-, and distal levels and selected the maximum peak value. Histopathology data were collected in a blinded fashion.
Change From Baseline in The Histopathologic Epithelial Features Combined Total Score at The Final Treatment Period EvaluationSecondary· Baseline, Week 16
Each esophageal biopsy specimen was evaluated microscopically by an independent, central pathologist for signs of epithelial inflammation and lamina propria fibrosis. Histopathologic epithelial features of each available esophageal level biopsy consisting of basal layer hyperplasia, eosinophil peak, dilated intercellular spaces, eosinophil microabcesses, surface layering, surface alteration, and apoptotic epithelial cells were scored and summed. Histopathology data were collected in a blinded fashion. Histopathology epithelial features were scored for both grade and stage. Each feature had a p
Change From Baseline in The Total Endoscopy Score at The Final Treatment Period EvaluationSecondary· Baseline, Week 16
The gross endoscopic appearance of the esophageal surface was evaluated by a blinded study center physician. Endoscopic findings with separate evaluations of the proximal and distal esophagus were recorded with respect to 5 major categories, including exudates or plaques, fixed esophageal rings, edema, furrows, and strictures. The endoscopy score was the sum of the scores for the 5 major categories - grade 0-1 for strictures; grade 0-2 for exudates or plaques, edema, and furrows; and grade 0-3 for fixed esophageal rings for the proximal and distal locations. The maximum endoscopy score was 10
Change From Baseline in The Peak Eosinophil Count at Each Available Esophageal Level at The Final Treatment Period EvaluationSecondary· Baseline, Week 16
An independent, central pathologist determined the peak eosinophil count from the proximal, mid-, and distal levels and selected the maximum peak value across all available esophagus levels. Histopathology data were collected in a blinded fashion. Baseline was defined as the score at screening. A negative change from baseline indicates that eosinophil count decreased.
Change From Baseline in The Physician's Global Assessment (PGA) of Disease Activity at The Final Treatment Period EvaluationSecondary· Baseline, Week 16
The physician Investigator (or qualified physician's assistant or nurse practitioner) completed the PGA to provide the global assessment of eosinophilic esophagitis (EoE) disease activity using a 0 to 100 mm visual analog scale (VAS) scale. The VAS is a 100 mm horizontal line on which the right extreme (100) is labeled "worst possible disease activity" and the left extreme (0) is labeled "no disease activity". The PGA raters were instructed to consider the line for the VAS a continuum with their own medical opinion or judgment of extremes on either end and to draw a vertical line at a point th
Distribution of Responses For The Patient Global Impression of Change (PGIC) Survey at The Final Treatment EvaluationSecondary· Week 16
Participants evaluated the change in their dysphasia (food passing slowly/difficulty swallowing) since the start of the study (screening) by choosing 1 of 7 responses on the PGIC survey: much worse (-3), worse (-2), a little worse (-1), no change (0), a little better (1), better (2), or much better (3). The values reported are the percent of participants who chose that response.
