Inclusion criteria

  • Signed ,
  • Male or female patients, 18 to 75 years of age,
  • Confirmed clinico-pathological diagnosis of eosinophilic esophagitis (EoE) according to established diagnostic criteria
  • Active symptomatic and histological EoE
  • Negative pregnancy test in females of at baseline visit.

Exclusion criteria

Exclusion Criteria:

  • Clinical and endoscopic signs of gastroesophageal reflux disease (GERD),
  • Achalasia, scleroderma esophagus, or systemic sclerosis,
  • Other clinically evident causes than EoE for esophageal eosinophilia,
  • Any concomitant esophageal disease and relevant gastro-intestinal disease (celiac disease, inflammatory bowel disease, oropharyngeal or esophageal bacterial, viral, or fungal infection [candida esophagitis]),
  • Any relevant systemic disease (e.g., AIDS, active tuberculosis, or C),
  • If careful medical monitoring is not ensured: cardiovascular disease, diabetes mellitus, osteoporosis, active peptic ulcer disease, glaucoma, cataract, or infection,
  • Liver cirrhosis or portal hypertension,
  • History of cancer in the last five years,
  • History of esophageal surgery at any time or of esophageal dilation procedures within the last 4 weeks prior to screening visit, or need for an immediate endoscopic intervention due to a stricture
  • Upper gastrointestinal bleeding within 8 weeks prior to baseline visit,
  • Existing or intended pregnancy or breast-feeding.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
