The Secondary Beneficial Effects of Prostaglandin Analog Treatment in Thyroid Eye Disease Patients.

May 14, 2018 updated by: Andrea L Kossler, Stanford University
The purpose of this study is to evaluate the potential secondary beneficial effect of prostaglandin analogues (PA) treatment in thyroid eye disease (TED) patients. This study aims to determine if PA would change the course of the orbitopathy in TED patients by altering the progression of the common features of TED, including fatty hypertrophy, proptosis, eyelid retraction and optic nerve compression. The eyes with thyroid eye disease and elevated intraocular pressure will be randomised to the PA treatment and the other eye will serve as a control eye and will be treated with Timolol.

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.

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.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Prostaglandin Analog vs Timolol
In this group, with thyroid eye disease and increased intraocular pressure in both eyes, prostaglandin analog eyedrop (bimatoprost 0.01%, travoprost z 0.004%, tafluprost 0.0015% or latanoprost 0.005%) will be administered once a day, topically, into one - randomised eye. Timolol 0.5% eye drop will be administered topically in second, control eye, two times a day.
Drug: Prostaglandin Analog
The first choice drug from group of Prostaglandin Analogues will be bimatoprost, if patient will suffer from any side effect of this drug another drug from this group will be administer. If patient turned out to cannot tolerate the prostaglandin analog therapy then the exclusion criteria will be met.
Other Names:
  • Latanoprost
  • Bimatoprost
  • Travoprost Z
  • Tafluprost
Drug: Timolol
Timolol topical eye drop will be administered in Prostaglandin Analog vs Timolol arm only, in patients with elevated intraocular pressure in both eyes.
Other Names:
  • Timolol maleate 0.5%
Experimental: Prostaglandin Analog
In this group, with thyroid eye disease and increased intraocular pressure in only one eye Prostaglandin Analog eyedrop (bimatoprost 0.01%, travoprost z 0.004%, tafluprost 0.0015% or latanoprost 0.005%) will be administered once a day, topically, into one, affected eye.
Drug: Prostaglandin Analog
The first choice drug from group of Prostaglandin Analogues will be bimatoprost, if patient will suffer from any side effect of this drug another drug from this group will be administer.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
