An Open-Label Trial of Losartan Potassium in Participants With Eosinophilic Esophagitis (EoE)

Study Purpose

The purpose of this study is to test the safety and effectiveness of Losartan potassium in subjects with Eosinophilic Esophagitis (EoE), both those with a connective tissue disorder (CTD) and those without a CTD.

Recruitment Criteria

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

Accepts Healthy Volunteers
No

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.

More Inclusion & Exclusion Criteria

Inclusion Criteria:

  • - Taking or planning to take hydrochlorothiazide, digoxin, warfarin, cimetidine, phenobarbital, rifampin, or fluconazole.
  • - taking or planning to take potassium supplements or salt substitutes containing potassium.
  • - A female participant who is pregnant or nursing or, if of childbearing potential, is not using a medically accepted, effective method of birth control (e.g., condom, oral/injectable/subcutaneous contraceptive, intrauterine device, or sexual abstinence).
  • - Participated/participating in any investigative drug or device study within 30 days prior to study entry.
  • - Participated/participating in any investigative biologics study within 3 months prior to study entry.

Trial Details

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.

Trial ID:
NCT03029091

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.

Additional Details

The purpose of this research study is to test the safety of Losartan potassium to see what effects (good and bad) it has on participants and their Eosinophilic Esophagitis (EoE). If a subject has Connective Tissue Disease (CTD) the researchers want to see what effects (good or bad) Losartan has on EoE. EoE is an inflammatory disease in the esophagus (the tube leading from the mouth to the stomach) that is typically triggered by exposure to certain things in food. Connective Tissue Disorders (CTDs) are disorders that affect the connective tissues in the body, such as fat, bone, and cartilage. Eosinophils release a protein called TGF-beta. Losartan may decrease the amount of the protein and therefore help EoE and CTD. Losartan is a drug that is approved by the United States Food and Drug Administration (FDA) for use in adults and children over 6 years of age who have high blood pressure. This medication has not been studied in people with EoE.
