Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Thyroid eye disease (TED) is a disease in which the soft tissues surrounding the eye can become inflamed, scarred, and at times permanently damaged in an autoimmune reaction highly associated with abnormal thyroid hormone levels. Some patients have much more severe TED than others, but overall, most patients reach a point with relatively stable TED after 1 to 2 years. A recent European study showed that oral selenium, a trace mineral involved in anti-oxidation and immune regulation, could actually alter the course of mild TED, lessening its signs and symptoms and even improving the quality of life of those who took it. The investigators would like to perform a sister study throughout North America. In this randomized, double-blinded, multi-center trial, some subjects with mild TED would be given 100 micrograms of sodium selenite twice a day; others would receive a placebo. Signs, symptoms, and quality of life would be measured at regular intervals throughout the 6 month period of drug administration, and for 6 months thereafter.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
