Standalone iStent Infinite and iDose TR for Management of Moderate to Severe Open Angle Glaucoma (POAG)

November 13, 2025 updated by: Jonathon Myers

iStent Infinite and iDose TR for Management of Moderate to Severe Primary Open Angle Glaucoma Are a Safe and Effective Alternative to Filtering Surgery for IOP Reduction in Patients With Medically Uncontrolled Glaucoma. (POAG)

The Investigators will investigate the efficacy of combining the standalone iStent infinite and iDose that are minimally invasive surgical and drug depot options are a safe and effective alternative to filtering surgery for intraocuar pressure reduction in patients with medically uncontrolled open angle glaucoma.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

The Investigators will assess the mean intraocular pressure change from baseline, the change in the number of medications from baseline, the proportion of patients needing additional incisional surgery, and the incidence of adverse events. The Investigators hypothesize that patients receiving the combined standalone iStent infinite and iDose will experience a safe and significant reduction in mean intraocular pressure and number of medications during the study time period.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

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
IOP reduction from baseline
Time Frame: Diurnal IOP reduction from baseline at 12 months
a logistic regression model will be used for the imputation of missing values, using the 12-month performance outcome as dependent variable, and sex, race, age, baseline IOP, number of IOP-lowering medications used at baseline, last IOP and number of medications at the 6-month visit or later as explanatory variables.
