入选标准

  • - Patients 12 to 65 years of age, inclusive, at the time of signing the informed consent or assent (if applicable) form.
  • -Documented previous diagnosis of EoE by endoscopy (documented diagnosis defined as an esophageal count of =15 eos/hpf on at least 1
  • esophageal level) and confirmed diagnosis by a centrally-read esophageal biopsy for the purposes of this study (confirmed diagnosis defined as an esophageal count of =15 eos/hpf at 2 or more esophageal levels).
  • Two to 4 biopsies should be obtained from both the proximal and distal esophagus.
  • Biopsies can be taken from the mid-esophagus for additional evaluation.
  • -Must be symptomatic at Visit 1 (screening) and Visit 2 (randomization):
  • (a) A patient reported average of at least 2 days per week with an episode of dysphagia over the 4 weeks prior to Visit 1 AND
  • (b) An average of at least 2 days per week with an episode of dysphagia (Daily DSQ =2) between Visit 1 and Visit 2, and at least 2 days per week
  • with an episode of dysphagia (Daily DSQ =2) in each of the 2 weeks immediately prior to randomization
  • -Must be adherent to daily diary assessments:
  • (a) Must complete 70% of daily diaries between Visit 1 and Visit 2; AND
  • (b) Must have completed at least 8 of 14 daily diaries in the 14 days prior to randomization.
  • -May be on background medications for EoE and related treatments during the study as long as the background medications have been stable for at least 4 weeks (8 weeks for PPI) prior to screening.
  • -Body weight of at least 35 kg.
  • -Negative serum pregnancy test for female patients of childbearing potential at Visit1.
  • -Women of childbearing potential must agree to use a highly effective form of birth control (confirmed by the Investigator) from randomization throughout the study duration and within 16 weeks after last dose if IP.
  • Are the trial subjects under 18? yes
  • Number of subjects for this age range: 40
  • F.1.2 Adults (18-64 years) yes
  • F.1.2.1 Number of subjects for this age range 130
  • F.1.3 Elderly (>=65 years) no
  • F.1.3.1 Number of subjects for this age range

排除标准

  • -Other GI disorders such as active Helicobacter pylori infection, history of achalasia, esophageal varices, Crohn's disease, ulcerative colitis, inflammatory bowel disease, or celiac disease.
  • -Esophageal stricture that prevents the easy passage of a standard endoscope or any critical esophageal stricture that requires dilation during the run-in period.
  • -Esophageal dilation performed within 8 weeks prior to screening and prior esophageal surgery would impact the assessments for EoE.
  • -Use of a feeding tube, or having a pattern of not eating solid food daily during the run-in period.
  • -Hypereosinophilic syndrome, defined by multiple organ involvement and persistent blood eosinophil count >1500 eos/µL.
  • -EGPA vasculitis.
  • -Eosinophilic gastritis, gastroenteritis, enteritis, or colitis documented by biopsy.
  • -Current malignancy, or history of malignancy with some specific exceptions.
  • -History of anaphylaxis to any biologic therapy or vaccine.
  • -Current active liver disease:
  • a) Chronic stable hepatitis B and C (including positive testing for hepatitis B surface antigen [HBsAg] or hepatitis C antibody), or other stable chronic liver disease are acceptable if the patient otherwise meets eligibility criteria.
  • b) Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) level=3 times the upper limit of normal (ULN), confirmed by repeated testing during the run-in period.
  • -Helminth parasitic infection diagnosed within 24 weeks prior to screening that has not been treated with or has failed to respond to standard of care therapy.
  • -History of known immunodeficiency disorder including a positive human immunodeficiency virus (HIV) test.
  • -Concomitant use of immunosuppressive medication.
