Phase 3
Waitlist Available
Research Sponsored by Glaukos Corporation
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial Must have
Zero to three preoperative ocular hypotensive medications
Diagnosed with open-angle glaucoma or ocular hypertension.

Awards & highlights
No Placebo-Only Group
Pivotal Trial
Summary
This trial is testing small devices placed inside the eye that slowly release a medication called travoprost. It aims to help people with open-angle glaucoma or ocular hypertension by lowering their eye pressure. The study compares these implants to another treatment to see which works better and is safer.
Who is the study for?
This trial is for people with open-angle glaucoma or ocular hypertension. Participants can have a cup-to-disc ratio of up to 0.8 and may be using up to three medications to lower eye pressure. Those with active corneal inflammation, edema, or retinal disorders unrelated to glaucoma cannot join.
What is being tested?
The study is testing two versions of a travoprost-releasing intraocular implant against Timolol Maleate Ophthalmic Solution (a standard treatment) in reducing high eye pressure caused by glaucoma or hypertension. It's a Phase III trial where one group gets the implants and another uses timolol drops.
What are the potential side effects?
Possible side effects include discomfort from the sham surgery or implant procedure, potential irritation from the eye drops, and any typical risks associated with intraocular devices such as infection or changes in vision.

Side Effect Profile
Prior Approvals
Other Research
Common treatments for Ocular Hypertension include prostaglandin analogs like Travoprost, which increase the outflow of aqueous humor, thereby reducing intraocular pressure (IOP). This is particularly important as elevated IOP is a major risk factor for glaucoma.
Other treatments include beta-blockers, which decrease aqueous humor production, and alpha agonists, which both decrease production and increase outflow. Carbonic anhydrase inhibitors also reduce aqueous humor production.
Understanding these mechanisms helps in choosing the most effective treatment with minimal side effects, tailored to the patient's specific needs.
