Exclusion criteria

Exclusion Criteria:

  3. Eosinophilic infiltration isolated to the esophagus.
  4. Pregnancy
  5. Immunodeficiency states

Past or current medical problems or findings from physical examination or laboratory testing that are not listed above, which, in the opinion of the investigator, may pose additional risks from participation in the study, may interfere with the participant's ability to comply with study requirements or that may impact the quality or interpretation of the data obtained from the study.
Terms in these criteria, in plain language(7)

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.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

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.

Reproductive potential

Able to have children. For women this usually means from the first period until menopause, unless permanently unable to through surgery; for men, unless permanently sterile. Read who the line is about — participants, women, men, or their partners.

Criteria about it usually ask for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

What researchers measure

Primary outcomes

  1. Percent of Participants in Complete Histologic Remission

    Percent of patients who have achieved complete histologic remission. Complete histologic remission is defined as normalization of gastric mucosal eosinophilia (histology with less than the diagnostic threshold levels of mucosal eosinophilia (\<30 eosinophils per high power field (HPF))

    Time frame: 6 weeks after treatment

Secondary outcomes

  1. Percent of Participants in Partial Histologic Remission

    Percent of participants in partial histologic remission. Partial remission is defined as 50% or more reduction in the maximum of gastric and duodenal peak eosinophil count.

    Time frame: 6 weeks after treatment

  2. Mean Change From Baseline in Maximum Eosinophil Count

    The maximum between gastric and duodenal eosinophil counts per high power field were obtained at baseline and 6 weeks. Mean change in count is defined as maximum eosinophil count per high power field (hpf) at 6 weeks minus maximum eosinophil count per hpf at baseline. A reduction (negative change from baseline) in eosinophil count per hpf indicates improvement. Eosinophil counts per hpf from gastric and duodenal biopsies were assessed by research pathologists at 400X magnification.

    Time frame: Baseline, 6 weeks after treatment

  3. Change From Baseline in Total Gastric Endoscopic Reference Score

    The gastric endoscopic reference score utilizes standardized criteria for the presence and degree of major endoscopic features. Overall scores range from 0 - 10. Endoscopic features were assessed at baseline and 6 weeks. Change in overall endoscopic reference score is defined as overall score at 6 weeks minus overall score at baseline. A reduction (negative change) in score indicates improvement.

    Time frame: Baseline, 6 weeks after treatment

  4. Change From Baseline in Symptoms of Dyspepsia (SODA)

    The SODA questionnaire captures symptoms associated with gastric dyspepsia including symptoms associated with "pain" and "non-pain" as well as general satisfaction with present symptoms. The scores range from 0 to 47 for pain; 0 to 35 for non-pain, and 0 to 23 for satisfaction. Higher scores indicate more frequent and/or severe symptoms for pain and non-pain. Higher scores indicate greater satisfaction. Scores were obtained at baseline and 6 weeks. Change in score is defined as total score at 6 weeks minus total score at baseline. A reduction (negative change) indicates improvement in pain and non-pain. An increase (positive change) indicates improvement in satisfaction.

    Time frame: Baseline, 6 weeks after treatment

  5. Change From Baseline in Promis Anxiety

    The Promis 29 questionnaire was used to assess anxiety. The range of scores for the anxiety sub-domain is 4 - 20 (raw score) with T-scores ranging from 40 to 82. A higher T-score indicates greater anxiety. Scores were obtained at baseline and 6 weeks. Change in score is defined as total score at 6 weeks minus total score at baseline.

    Time frame: Baseline, 6 weeks after treatment

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 27, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
