EoE RCT Fluticasone and Omeprazole vs Fluticasone Alone

Study Purpose

The purpose of this study is to evaluate the efficacy of combination therapy with omeprazole and swallowed fluticasone vs.#46;fluticasone therapy and placebo in the treatment of Eosinophilic Esophagitis (EoE) in children and adults. This study will be a double-blinded, randomized controlled trial. The primary outcome measured will be histologic assessment of esophageal tissue biopsies measuring number of eosinophils per high power field (eos/hpf). Secondary outcomes will be endoscopic findings and symptomatic changes following therapy using validated endoscopic scoring measures and participant surveys, respectively.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT03781596
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Eosinophilic Esophagitis
Additional Details

Subjects that meet study inclusion criteria will be recruited from the Adult and Pediatric Gastroenterology clinics at Walter Reed National Military Medical Center through routine clinic visits, will meet with an investigator, and complete informed consent/assent. The participants will then complete a validated clinical symptom reporting tool

  • - the Eosinophilic Esophagitis symptom activity index (EEsAI) for age 18 and above, or the Pediatric Quality of Life Inventory (PedsQL) for age 6-17yrs - and have their initial Esophagogastroduodenoscopy (EGD) images evaluated via a validated Endoscopic Reference Score (EREFS).
Esophageal biopsies taken at the patient's initial EGD will be assessed by 2 designated blinded pathologists to record the number of eosinophils per high power field (HPF), as well as perform tissue immunohistochemical staining for eotaxin-3. Participants will be block randomized to treatment or control groups and complete 8 weeks of therapy, with a phone follow up at 4 weeks for medication compliance. At the completion of 8 weeks of therapy, the participants will have repeat EGD to assess for mucosal healing, which is the standard of care in the treatment of EoE. At this EGD, the images will be assigned an EREFS and the biopsies will be evaluated for eosinophils per high powered field and eotaxin-3 staining. The patient will also complete an EEsAI or PedsQL. This procedure will end the 8 week study period.

Arms & Interventions

Arms

Experimental: Fluticasone and omeprazole

These patients will be prescribed swallowed fluticasone and omeprazole to be taken together for the 8 week period. Dosing will be based on weight and age. Primary outcome measure will be the change in esophageal biopsy histology, or number of eosinophils per high powered field, from week 0 to week 8. Secondary outcomes will include changes in the following variables between week 0 and 8: eotaxin staining of the esophageal biopsy tissue, endoscopic scoring from photos of the esophagus obtained during endoscopy, and symptom scoring based on surveys.

Placebo Comparator: Fluticasone and placebo

These patients will be prescribed swallowed fluticasone and a placebo medication that appears identical to omeprazole to be taken together for an 8 week period. Dosing will be based on weight and age. Primary outcome measure will be the change in esophageal biopsy histology, or number of eosinophils per high powered field, from week 0 to week 8. Secondary outcomes will include changes in the following variables between week 0 and 8: eotaxin staining of the esophageal biopsy tissue, endoscopic scoring from photos of the esophagus obtained during endoscopy, and symptom scoring based on surveys.

Interventions

Diagnostic Test: - Retrospective evaluation of endoscopy prior to study drug

Once enrolled, the patient's original endoscopy will be evaluated including the images from the EGD and the biopsies for eotaxin 3 staining and eosinophilic burden.

Other: - Symptom Survey

Patient will complete symptom survey prior to starting the study drugs.

Other: - Medication Compliance Phone Call

The patient will receive a phone call at 4 weeks to evaluate medication compliance including the number on the inhaler and the number of pills remaining in the container.

Diagnostic Test: - Endoscopy while on study drug

Endoscopy will be performed after 8 weeks of therapy. Endoscopic scoring will be assigned and the histology will be evaluated, including eotaxin 3 staining. The change in eosinophil count and eotaxin staining will be measured.

Other: - Symptom Survey

The patient will complete a symptom survey after 8 weeks on the study drugs, and the change in survey score will be measured.

Drug: - Fluticasone

Participants in the experimental and placebo arms will be given swallowed fluticasone for an 8 week course. Doses determined by age and weight.

Drug: - Omeprazole

The participants in the experimental arm will be given oral omprazole capsules for an 8 week period (along with the swallowed fluticasone). Doses determined by age and weight.

Drug: - Placebo oral capsule

The participants in the placebo arm will be given placebo capsules for an 8 week period (along with the swallowed fluticasone). Number of pills determined by age and weight (to match omeprazole dosing).
