Oral Cromolyn Sodium for the Treatment of Eosinophilic Esophagitis

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02371941

Brief Summary:
This is a randomized, double-blind, placebo-controlled study of oral cromolyn sodium when made into a viscous preparation for the treatment of eosinophilic esophagitis.

Condition or disease Intervention/treatment Phase
Eosinophilic Esophagitis Drug: oral cromolyn sodium Drug: Placebo Phase 4

Detailed Description:

Eosinophilic esophagitis is an antigen-mediated allergic disease of the esophagus characterized by symptoms of gastrointestinal complaints and eosinophilic inflammation limited to the esophagus. Currently, first line therapeutic recommendations include swallowed, topical steroids or dietary therapy. While both work for the majority of patients, they both have limitations.

The investigators are examining the use of oral cromolyn sodium as a treatment for this condition. This medication is a non-steroid that is already approved for other conditions. When taken orally, it is essentially not absorbed systemically, so side effects are minimal. There is only 1 brief, retrospective report of its use in this condition suggesting it does not work. However, from studying swallowed, topical steroids, it may require formulating the medication into a viscous preparation for it to work.

Actual Study Completion Date : December 2017

Arm Intervention/treatment
Experimental: Oral cromolyn

Subjects randomized to the experimental arm will receive oral cromolyn sodium. The dose will be per current package insert for oral cromolyn:

Subjects 2-12 years of age - 100 mg (1 ampule) 4 times daily Subjects 13-18 years of age - 200 mg (2 ampules) 4 times daily

Drug: oral cromolyn sodium
Oral cromolyn sodium
Other Name: Gastrocrom

Placebo Comparator: Placebo
Subjects randomized to placebo will receive normal saline ampules Subjects 2-12 years of age - 1 ampule 4 times daily Subjects 13-18 years of age - 2 ampules 4 times daily
Drug: Placebo

Primary Outcome Measures :
  1. Peak esophageal eosinophil count [ Time Frame: 2 months ]
    Measure of the peak esophageal eosinophil count on esophageal biopsy specimens after 2 months of therapy

Secondary Outcome Measures :
  1. Symptoms as measured by Pediatric Eosinophilic Esophagitis Symptom Score [ Time Frame: 1 month and 2 month ]
    Symptom scores will be measures at baseline, 1 month, and 2 months using a symptom scoring assessment tool known as the Pediatric Eosinophilic Esophagitis Symptom Score.
