An Observational Study of Patients With Primary Open Angle Glaucoma (POAG) or Ocular Hypertension (OHT) Who Switched IOP-lowering Treatments

April 9, 2019 updated by: Allergan
This study is a prospective, observational study of changing from any IOP-lowering treatment to a prostaglandin analogue-containing IOP-lowering medication for patients with Primary Open Angle Glaucoma (POAG) or Ocular Hypertension (OHT). The decision to change medications lies with the physician according to their standard practice.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

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

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Patients with POAG or OHT
Patients with POAG or OHT on current IOP-lowering therapy who are prescribed a prostaglandin analogue -containing IOP-lowering therapy by the physician. The decision to prescribe a change in IOP-lowering therapy lies with the physician according to their standard practice.
Drug: Prostaglandin Analogue -Containing IOP-Lowering Therapy
Patients with POAG or OHT on current IOP-lowering therapy who are prescribed a prostaglandin analogue -containing IOP-lowering therapy by the physician. The decision to prescribe a change in IOP-lowering therapy lies with the physician according to their standard practice.

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
Measure Description
Time Frame
Change From Baseline in Intraocular Pressure (IOP) in the Right Eye
Time Frame: Baseline, Week 12
IOP is a measurement of the fluid pressure inside the eye. A negative change from Baseline indicates an improvement.
Baseline, Week 12
Change From Baseline in Intraocular Pressure (IOP) in the Left Eye
Time Frame: Baseline, Week 12
IOP is a measurement of the fluid pressure inside the eye. A negative change from Baseline indicates an improvement.
Baseline, Week 12

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.
Outcome Measure
Measure Description
Time Frame
Patient Assessment of Overall Tolerability With New Treatment Using a 4-Point Scale
Time Frame: 12 Weeks
The patient evaluated the tolerability of IOP-lowering medication therapy using a 4-Point Scale: Very good, Good, Moderate or Poor. Percentage of participants in each category is reported.
12 Weeks
Physician Assessment of Tolerability With New Treatment Using a 4-Point Scale
Time Frame: 12 Weeks
The physician evaluated the patient's tolerability of IOP-lowering medication therapy using a 4-Point Scale: Very good, Good, Moderate or Poor. Percentage of participants in each category is reported.
12 Weeks
Percentage of Participants Who Discontinue the Use of New Treatment Prior to 12 Weeks
Time Frame: 12 Weeks
12 Weeks
Percentage of Participants Who Continue the New Treatment After 12 Weeks
Time Frame: 12 Weeks
12 Weeks
Physician Assessment of Adherence to New Treatment Using a 4-Point Scale
Time Frame: 12 Weeks
The physician assessed the participant's adherence to new treatment using the following scale: Not Applicable, Worse, Equal or Better. The percentage of participants in each category is reported.
12 Weeks
Physician Assessment of Efficacy Using a 5-Point Scale
Time Frame: 12 Weeks
The physician evaluated efficacy (IOP lowering) using a 5-Point Scale: IOP lower than target, Reached Target IOP, IOP decreased but target not reached, No change or IOP increased. The percentage of participants in each category is reported.
12 Weeks
Percentage of Participants Reaching Individual IOP Target After 12 Weeks
Time Frame: 12 Weeks
12 Weeks

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
